15 Top Low Carb Keto Side Dishes

Sticking to a ketogenic diet often means focusing intently on the main course – the perfect steak, juicy chicken, or flaky fish. But what about the supporting cast? Side dishes can make or break a meal, and on keto, it's easy to fall into a rut of plain steamed broccoli or simple salads. Fear not! Elevating your keto meals is easier than you think.

The world of low-carb vegetables and healthy fats offers a surprisingly vast playground for creating delicious, satisfying, and visually appealing side dishes. Gone are the days of missing potatoes, pasta, or rice. With a little creativity and the right ingredients, you can whip up sides that are not only compliant with your keto goals but are so flavourful they might just steal the show.

This guide dives into 15 top-tier low carb keto side dishes designed to complement any main course. From creamy and comforting to bright and zesty, these recipes offer variety, taste, and crucial nutrients, all while keeping the carb count low. Get ready to transform your keto dinners from routine to remarkable.

1. Creamy Cauliflower Mash (The Keto Potato Swap)

Mashed potatoes are a classic comfort food, but their high carb count makes them a no-go on keto. Enter Creamy Cauliflower Mash – the undisputed champion of keto side dish swaps. When prepared correctly, it achieves a remarkably similar texture and serves as a perfect vehicle for butter, gravy, or herbs.

Why it's a Keto Staple:

Cauliflower is incredibly low in carbs and calories but rich in vitamins and fiber. It mimics the texture of potatoes surprisingly well when steamed and blended.

Key Ingredients:

• Fresh Cauliflower Florets

• Butter or Ghee

• Heavy Cream or Cream Cheese

• Salt and Pepper

• Optional: Garlic, Chives, Sour Cream, Parmesan Cheese

Simple Steps:

Steam or boil cauliflower florets until very tender. Drain thoroughly – excess water is the enemy of creamy mash! Blend the cauliflower with butter, cream (or cream cheese), salt, and pepper until smooth. A food processor or immersion blender works best for achieving a silky texture.

Tips for Perfection:

• Drain Well: Squeeze out excess moisture from the steamed cauliflower using a cheesecloth or clean kitchen towel for the best texture.

• Add Fat: Don't skimp on the butter, ghee, or cream cheese. Fat adds flavour and contributes to the creamy consistency.

• Season Boldly: Cauliflower has a mild flavour, so be generous with salt, pepper, and any additional seasonings like garlic powder or onion powder.

Variations:

• Cheesy Cauliflower Mash: Stir in shredded cheddar, Parmesan, or Gruyere cheese.

• Garlic Herb Mash: Add roasted garlic and fresh herbs like chives, parsley, or thyme.

• Loaded Mash: Top with crispy bacon bits, sour cream, and shredded cheese.

2. Roasted Brussels Sprouts with Bacon

Brussels sprouts have undergone a culinary renaissance, and roasting is arguably the best way to enjoy them. Roasting brings out their natural sweetness and creates delightful crispy edges. Adding bacon takes them to another level of savoury deliciousness.

Why it's Keto-Friendly:

Brussels sprouts are a cruciferous vegetable packed with nutrients and relatively low in net carbs. Bacon adds healthy fats and incredible flavour without significant carbs.

Key Ingredients:

• Fresh Brussels Sprouts

• Bacon (Sugar-free recommended)

• Olive Oil or Avocado Oil

• Salt and Pepper

• Optional: Balsamic Glaze (use sparingly or keto-friendly version), Garlic Powder, Red Pepper Flakes

Simple Steps:

Trim and halve the Brussels sprouts. Chop the bacon. Toss the sprouts with oil, salt, pepper, and any optional seasonings. Spread on a baking sheet, ideally with the bacon scattered amongst them (or cook bacon separately and crumble over later). Roast at a high temperature (around 400°F/200°C) until tender and caramelized, with crispy edges.

Why it Works:

The high heat transforms the sprouts from potentially bitter to nutty and slightly sweet. The bacon renders its fat, infusing the sprouts with flavour and contributing to the crispiness.

Cooking Tips:

• High Heat is Key: Ensures proper caramelization and prevents sogginess.

• Don't Overcrowd the Pan: Give the sprouts space for air to circulate, promoting crispiness. Use two pans if necessary.

• Cut Uniformly: Halve or quarter larger sprouts so they cook evenly.

3. Creamed Spinach with Parmesan

Creamed spinach is a steakhouse classic that translates beautifully to the keto diet. It's rich, decadent, and packed with nutrients from the spinach, balanced by creamy, cheesy goodness.

Why it's Great for Keto:

Spinach is extremely low in carbs and high in vitamins and minerals. Heavy cream, cream cheese, and Parmesan cheese provide healthy fats and minimal carbs, making this a satisfying and compliant side.

Key Ingredients:

• Fresh Spinach or Frozen Spinach (thawed and squeezed dry)

• Butter

• Garlic

• Heavy Cream

• Cream Cheese

• Grated Parmesan Cheese

• Salt, Pepper, Nutmeg (optional)

Simple Steps:

If using fresh spinach, wilt it in a pan (you might need to do this in batches). If using frozen, ensure it's thoroughly thawed and squeezed dry to remove excess water. In the same pan, melt butter and sauté minced garlic until fragrant. Stir in cream cheese until melted, then add heavy cream and Parmesan. Simmer gently until thickened. Stir in the spinach, season with salt, pepper, and a pinch of nutmeg (if desired).

Tips for Success:

• Dry Spinach is Crucial: Especially important with frozen spinach to avoid a watery result.

• Use Full-Fat Dairy: Heavy cream and full-fat cream cheese provide the best flavour and texture.

• Freshly Grated Parmesan: Melts better and has superior flavour compared to pre-grated varieties.

Variations:

• Add Artichoke Hearts: For a keto-friendly spinach and artichoke dip vibe, stir in chopped artichoke hearts.

• Spicy Kick: Add a pinch of red pepper flakes.

• Bacon Bits: Because bacon makes everything better.

4. Cheesy Baked Asparagus

Asparagus is an elegant and nutritious vegetable that becomes utterly irresistible when roasted with cheese. It’s quick to prepare and makes a fantastic side for almost any protein.

Why it Fits Keto:

Asparagus is low in carbs and a good source of fiber and vitamins. Cheese adds fat and flavour, enhancing satiety.

Key Ingredients:

• Fresh Asparagus Spears

• Olive Oil or Avocado Oil

• Garlic Powder

• Salt and Pepper

• Shredded Cheese (Mozzarella, Parmesan, or a blend)

• Optional: Lemon Zest, Red Pepper Flakes

Simple Steps:

Preheat your oven. Trim the tough woody ends off the asparagus spears. Toss the asparagus with oil, garlic powder, salt, and pepper. Arrange in a single layer on a baking sheet or in a baking dish. Roast for about 10-15 minutes, depending on thickness, until tender-crisp. Sprinkle generously with cheese and return to the oven for a few more minutes until the cheese is melted and bubbly, possibly finishing under the broiler for extra browning.

Serving Suggestions:

• A squeeze of fresh lemon juice after baking brightens the flavours.

• Perfect alongside grilled steak, salmon, or chicken.

Make it Crispier:

• Ensure asparagus is dry before tossing with oil.

• Roast at a reasonably high temperature (around 400°F/200°C).

• Don't overcrowd the pan.

5. Zucchini Noodles (Zoodles) with Pesto

Missing pasta? Zucchini noodles, or "zoodles," are a popular low-carb alternative. When tossed with a flavourful, high-fat pesto sauce, they create a light yet satisfying side dish.

Why it's Keto-Approved:

Zucchini is very low in carbohydrates and calories. Traditional pesto, made with basil, pine nuts (or walnuts/macadamia nuts for lower carbs), Parmesan, garlic, and olive oil, is naturally high in healthy fats and low in carbs.

Key Ingredients:

• Fresh Zucchini

• Keto-Friendly Pesto (store-bought or homemade)

• Olive Oil or Butter

• Salt and Pepper

• Optional: Cherry Tomatoes (use sparingly), Toasted Pine Nuts or Walnuts, Extra Parmesan

Simple Steps:

Use a spiralizer to create zucchini noodles. Alternatively, use a julienne peeler or mandoline. Gently sauté the zoodles in a pan with a little olive oil or butter for just a minute or two – you want them tender-crisp, not mushy. Overcooking releases too much water. Remove from heat, drain any excess liquid, and toss gently with pesto, salt, and pepper.

Avoiding Soggy Zoodles:

• Don't Overcook: Sauté very briefly (1-3 minutes max).

• Salt Strategically: Salting zucchini draws out water. Some prefer to salt the zoodles beforehand, let them sit in a colander for 20-30 minutes, then pat them dry before cooking. Others skip this and just drain well after the brief sauté.

• Thicker Sauce: Ensure your pesto isn't too thin.

Homemade Keto Pesto Tip:

Swap traditional pine nuts (moderate carbs) for lower-carb nuts like macadamia nuts or walnuts.

6. Keto Coleslaw

Traditional coleslaw is often loaded with sugar. This keto version delivers the same creamy, crunchy satisfaction without the carb overload, using a sugar-free dressing.

Why it's a Keto Winner:

Cabbage and carrots (in moderation) are relatively low-carb vegetables. The dressing uses mayonnaise (a great source of fat) and a keto-friendly sweetener instead of sugar.

Key Ingredients:

• Shredded Cabbage (green and/or red)

• Shredded Carrots (use sparingly for colour and flavour)

• Mayonnaise (check for sugar-free/avocado oil options)

• Apple Cider Vinegar or White Vinegar

• Keto-Friendly Sweetener (e.g., erythritol, stevia)

• Salt and Pepper

• Optional: Dijon Mustard, Celery Seeds, Chopped Onion or Scallions

Simple Steps:

In a large bowl, combine the shredded cabbage and carrots. In a smaller bowl, whisk together the mayonnaise, vinegar, sweetener, salt, pepper, and any optional ingredients like mustard or celery seeds. Pour the dressing over the cabbage mixture and toss well to coat evenly. For best results, chill for at least 30 minutes before serving to allow the flavours to meld.

Customization Ideas:

• Add Texture: Stir in some chopped celery, bell peppers (in moderation), or sunflower seeds.

• Spicy Slaw: Add a dash of hot sauce or some finely diced jalapeño.

• Broccoli Slaw: Use pre-shredded broccoli slaw mix instead of or in addition to cabbage.

7. Garlic Butter Mushrooms

Mushrooms sautéed in garlic butter are simple, quick, and incredibly flavourful. They pair beautifully with steaks, chicken, or pork chops.

Why They Work for Keto:

Mushrooms are low in carbs and calories but offer umami depth. Butter provides healthy fats, and garlic adds aromatic flavour.

Key Ingredients:

• Fresh Mushrooms (Cremini, Button, or Shiitake work well)

• Butter

• Garlic (minced)

• Salt and Pepper

• Fresh Parsley or Thyme (optional)

• Splash of Dry White Wine or Broth (optional)

Simple Steps:

Clean the mushrooms and slice or halve them depending on size. Melt butter in a skillet over medium heat. Add the mushrooms and cook, stirring occasionally, until they release their liquid and start to brown. Add minced garlic and cook for another minute until fragrant (don't let it burn). If using, deglaze the pan with a splash of wine or broth. Season with salt and pepper. Stir in fresh herbs just before serving.

Achieving Perfect Sautéed Mushrooms:

• Don't Crowd the Pan: Cook in batches if necessary to allow mushrooms to brown rather than steam.

• Medium-High Heat: Helps evaporate moisture and encourages browning.

• Patience: Let them cook undisturbed for periods to develop colour.

8. Cheesy Garlic Roasted Radishes

Missing roasted potatoes? Roasted radishes offer a surprisingly similar texture when cooked – tender on the inside and slightly crispy outside. Roasting mellows their peppery bite, and adding garlic and cheese makes them truly delicious.

Why They're a Clever Keto Swap:

Radishes are root vegetables, but unlike potatoes, they are very low in carbohydrates. Roasting transforms their texture and flavour profile significantly.

Key Ingredients:

• Fresh Radishes

• Olive Oil or Avocado Oil

• Minced Garlic or Garlic Powder

• Salt and Pepper

• Grated Parmesan Cheese

• Fresh Parsley (optional)

Simple Steps:

Preheat your oven to around 400°F (200°C). Trim and halve or quarter the radishes depending on their size. Toss them with oil, garlic, salt, and pepper. Spread in a single layer on a baking sheet. Roast for 20-30 minutes, or until tender when pierced with a fork and slightly browned. Sprinkle with Parmesan cheese during the last 5-10 minutes of roasting. Garnish with fresh parsley if desired.

Flavour Notes:

• Roasting significantly reduces the sharp, peppery flavour of raw radishes.

• They become soft and slightly starchy, reminiscent of potatoes.

9. Simple Lemon-Herb Green Beans

Sometimes, simplicity shines. Fresh green beans quickly blanched or sautéed and tossed with lemon and herbs make a vibrant, refreshing side dish that cuts through richer mains.

Why They're Ideal for Keto:

Green beans are low in net carbs and provide fiber and vitamins. Lemon juice and herbs add flavour without adding carbs, while a touch of butter or olive oil provides healthy fats.

Key Ingredients:

• Fresh Green Beans (trimmed)

• Butter or Olive Oil

• Lemon (juice and zest)

• Fresh Herbs (Parsley, Dill, Chives, or Thyme work well)

• Salt and Pepper

• Optional: Sliced Almonds (toasted), Garlic

Simple Steps:

You can either blanch the green beans (boil briefly, then plunge into ice water to stop cooking and retain bright colour) or sauté them in a skillet with butter or oil until tender-crisp. If sautéing, you can add minced garlic for extra flavour. Once cooked, toss the green beans with lemon juice, lemon zest, chopped fresh herbs, salt, and pepper. Add toasted sliced almonds for crunch if desired.

Cooking Methods Compared:

• Blanching: Yields bright green, crisp-tender beans. Best for retaining colour.

• Sautéing: Can add more flavour directly during cooking (e.g., garlic butter) and potentially some charring.

10. Keto Caprese Salad Skewers

A fun and easy take on the classic Caprese salad, skewers are perfect for appetizers or a light side dish. They require no cooking and showcase fresh, simple flavours.

Why They're Keto-Friendly:

Mozzarella cheese provides fat and protein, tomatoes (used in moderation) offer freshness and are relatively low-carb, and basil adds flavour. Olive oil drizzle boosts healthy fats.

Key Ingredients:

• Cherry Tomatoes

• Small Fresh Mozzarella Balls (Bocconcini)

• Fresh Basil Leaves

• Extra Virgin Olive Oil

• Balsamic Glaze (Keto-friendly or used very sparingly)

• Salt and Pepper

• Skewers

Simple Steps:

Thread a cherry tomato, a basil leaf (folded if large), and a mozzarella ball onto each skewer. Repeat if desired for longer skewers. Arrange the skewers on a platter. Drizzle generously with extra virgin olive oil. Add a very light drizzle of balsamic glaze (optional, watch carbs) or use a keto balsamic alternative. Season with salt and freshly ground black pepper just before serving.

Presentation Matters:

Arrange attractively on a platter for a visually appealing side or appetizer.

11. Broccoli and Cheese Casserole

A comforting classic made keto! This casserole combines tender broccoli florets with a rich, creamy cheese sauce, baked until bubbly and golden.

Why it's Keto Comfort Food:

Broccoli is a low-carb powerhouse vegetable. The sauce relies on cheese, cream cheese, and heavy cream – all high in fat and low in carbs – instead of traditional flour-based roux or high-carb fillers like breadcrumbs.

Key Ingredients:

• Broccoli Florets (fresh or frozen, steamed until tender-crisp)

• Butter

• Cream Cheese

• Heavy Cream

• Shredded Cheddar Cheese (or a blend)

• Garlic Powder, Onion Powder

• Salt and Pepper

• Optional: Cooked Bacon Crumbles, Pork Rind Crumbs for topping

Simple Steps:

Preheat oven. Steam broccoli until just tender; drain well. In a saucepan, melt butter over medium heat. Stir in cream cheese until smooth. Gradually whisk in heavy cream. Stir in most of the shredded cheese, garlic powder, onion powder, salt, and pepper. Cook until cheese is melted and sauce is smooth. Combine the cheese sauce with the steamed broccoli in a baking dish. Top with remaining shredded cheese and optional bacon or pork rind crumbs. Bake until bubbly and golden brown.

Tips for Creaminess:

• Ensure broccoli is well-drained.

• Use full-fat dairy products.

• Don't over-boil the cheese sauce once cheese is added.

12. Sautéed Kale with Garlic and Lemon

Kale is a nutrient-dense leafy green that becomes tender and flavourful when sautéed with garlic and finished with a squeeze of lemon.

Why it's a Healthy Keto Choice:

Kale is exceptionally low in carbs and packed with vitamins (K, A, C) and minerals. Olive oil adds healthy fats, while garlic and lemon provide flavour without carbs.

Key Ingredients:

• Fresh Kale (Lacinato/Dinosaur or Curly), tough stems removed, leaves chopped

• Olive Oil

• Garlic (thinly sliced or minced)

• Salt and Pepper

• Lemon Juice

• Red Pepper Flakes (optional)

Simple Steps:

Heat olive oil in a large skillet or pot over medium heat. Add garlic and red pepper flakes (if using) and cook for about 30 seconds until fragrant. Add the chopped kale (it might seem like a lot, but it will wilt down). You may need to add it in batches. Stir frequently, cooking until the kale is wilted and tender, about 5-10 minutes. Season with salt and pepper. Remove from heat and stir in a generous squeeze of fresh lemon juice.

Taming Kale's Bitterness:

• Removing the tough center rib helps.

• Sautéing mellows the flavour.

• Lemon juice brightens and balances the taste.

13. Avocado and Cucumber Salad

A supremely refreshing, no-cook side dish perfect for warm weather or alongside spicy mains. It’s creamy, crunchy, and packed with healthy fats.

Why it's Perfectly Keto:

Avocado is a keto superstar, loaded with healthy monounsaturated fats and low in net carbs. Cucumber is hydrating and very low-carb. The simple dressing adds more healthy fat and flavour.

Key Ingredients:

• Ripe Avocados (diced)

• Cucumber (peeled, seeded, and diced)

• Red Onion (thinly sliced or minced, use sparingly)

• Fresh Cilantro or Parsley (chopped)

• Lime Juice or Lemon Juice

• Olive Oil

• Salt and Pepper

Simple Steps:

Gently combine the diced avocado, cucumber, red onion, and fresh herbs in a bowl. In a small separate bowl, whisk together the lime/lemon juice, olive oil, salt, and pepper. Pour the dressing over the avocado mixture and toss gently to combine, being careful not to mash the avocado too much. Serve immediately for the best texture and colour.

Tips for Freshness:

• Add the avocado last and toss gently.

• The acid from the lime/lemon juice helps prevent the avocado from browning too quickly, but it's still best served fresh.

14. Keto "Faux-tato" Salad (Cauliflower)

Craving potato salad at your next BBQ? This keto version uses cooked cauliflower florets instead of potatoes, mimicking the texture surprisingly well in a creamy, tangy dressing.

Why it's a Smart Swap:

Cauliflower provides the necessary bulk and texture with far fewer carbs than potatoes. The dressing ingredients (mayonnaise, mustard, vinegar) are naturally low-carb.

Key Ingredients:

• Cauliflower Florets (steamed or roasted until tender, then chopped)

• Mayonnaise (sugar-free)

• Dijon Mustard

• Apple Cider Vinegar

• Celery (finely chopped)

• Red Onion or Scallions (finely chopped)

• Hard-Boiled Eggs (chopped)

• Dill Pickles (sugar-free, chopped, optional)

• Salt, Pepper, Paprika

Simple Steps:

Steam or roast cauliflower florets until tender but not mushy. Let cool completely, then chop into small, bite-sized pieces. In a large bowl, combine the cooled cauliflower, chopped celery, onion/scallions, hard-boiled eggs, and pickles (if using). In a separate bowl, whisk together the mayonnaise, mustard, vinegar, salt, and pepper. Pour the dressing over the cauliflower mixture and gently stir to combine. Chill for at least an hour before serving to allow flavours to meld. Garnish with paprika.

Texture Tip:

Roasting the cauliflower instead of steaming can add a nice flavour dimension and help prevent excess moisture. Ensure it cools completely before mixing.

15. Cheesy Baked Spaghetti Squash

Spaghetti squash naturally forms strands that resemble pasta when cooked. Baking it with cheese and seasonings creates a satisfying, low-carb alternative to pasta bakes.

Why it's Keto-Friendly:

Spaghetti squash is lower in carbs than traditional pasta or other winter squashes. Cheese and butter add flavour and necessary keto fats.

Key Ingredients:

• Spaghetti Squash

• Butter or Olive Oil

• Garlic Powder

• Salt and Pepper

• Shredded Cheese (Mozzarella, Parmesan, Cheddar blend)

• Fresh Parsley (optional)

Simple Steps:

Preheat oven. Carefully cut the spaghetti squash in half lengthwise and scoop out the seeds. Brush the cut surfaces with olive oil or melted butter, season with salt, pepper, and garlic powder. Place cut-side down on a baking sheet and roast until tender (easily pierced with a fork). Let it cool slightly, then use a fork to scrape out the strands. Transfer the strands to a baking dish. You can mix in some butter, herbs, and some of the cheese directly with the strands. Top generously with the remaining shredded cheese. Bake again (or broil) until the cheese is melted, bubbly, and golden brown. Garnish with parsley if desired.

Cooking Spaghetti Squash:

• Roasting is generally preferred for better flavour and less moisture compared to boiling or microwaving.

• Cook time varies greatly depending on the size of the squash.

Choosing the Right Keto Side Dish

With so many delicious options, how do you pick the perfect side? Consider these factors:

• Main Course: Pair creamy sides (like cauliflower mash or creamed spinach) with leaner proteins or steaks. Opt for brighter, acidic sides (like lemon-herb green beans or Caprese skewers) with richer or fattier mains. Roasted vegetables (Brussels sprouts, radishes) complement almost anything.

• Occasion: A simple sautéed kale might be perfect for a weeknight, while a broccoli and cheese casserole or cheesy baked asparagus feels more special occasion or holiday-worthy.

• Prep Time: Zoodles, Caprese skewers, and avocado salad come together quickly. Roasted vegetables and casseroles require more oven time.

• Flavour Profile: Balance your meal. If your main dish is heavily spiced, choose a milder side. If the main is simple, let the side dish shine with bold flavours.

• Texture: Aim for variety. If your main course is soft, add a crunchy side like roasted Brussels sprouts or keto coleslaw.

Tips for Keto Side Dish Success

• Embrace Healthy Fats: Use olive oil, avocado oil, butter, ghee, coconut oil, and full-fat dairy generously for flavour and satiety.

• Season Well: Salt, pepper, herbs, spices, and garlic are your friends. Low-carb doesn't mean low-flavour.

• Don't Fear Vegetables: Focus on non-starchy, above-ground vegetables like leafy greens, broccoli, cauliflower, zucchini, asparagus, Brussels sprouts, bell peppers (in moderation), and mushrooms.

• Watch Hidden Carbs: Be mindful of sauces, dressings, and trace carbs in processed ingredients (like some cheeses or bacon). Opt for sugar-free condiments.

• Control Portions: While low-carb, calories still matter. Be mindful of portion sizes, especially with richer, cheese-laden dishes.

• Meal Prep: Many components (like chopping vegetables, making dressings, or even pre-roasting some items) can be done ahead of time to simplify weeknight cooking.

Exploring low carb keto side dishes opens up a world of flavour and culinary creativity. Moving beyond basic steamed vegetables allows you to create well-rounded, satisfying, and nutritionally balanced meals that fully support your ketogenic lifestyle. From the comforting creaminess of cauliflower mash and creamed spinach to the vibrant crunch of roasted Brussels sprouts and keto coleslaw, there's a perfect keto side dish for every occasion and every main course.
