For sweet potato duty, my top pick is the Kalorik MAXX Complete Air — its 26-quart cavity, 500°F ceiling and 21 presets let you roast whole sweet potatoes in bulk and still crisp a tray of fries right after.
• Kalorik MAXX Complete Air — best for feeding a family from one appliance; pick this if you want a 26-quart oven that can hold a 14-pound turkey or a 12-inch pizza and still run a rotisserie.
• GXF Air Fryer Grill — best for upgrading a Ninja you already own; pick this if your basket measures about 8.2 inches and you want a non-stick, dishwasher-safe grill plate with a grab handle.
• Chefman 3.5 — best for small kitchens and single portions; pick this if you want a compact 3.5-quart flat basket, a 60-minute timer with auto shutoff, and dishwasher-safe parts.
• Kreiaoer Glass Air Fryer — best for watching your food cook; pick this if you like the idea of a 4.44-quart borosilicate glass pot you can see through, plus a dedicated sweet potato preset.
This is less an air fryer and more a countertop oven that happens to air fry extremely well. Kalorik rates it at 26 quarts with 1700 watts, and the brand's Turbo MAXX claims put french fries up to 22% faster than a conventional oven's timing, chicken up to 27% faster and steak up to 37% faster. For sweet potatoes that matters in a practical way: a big oven-style cavity means you can lay several whole potatoes on the air rack without stacking them, so the hot air actually reaches every surface instead of steaming the ones underneath.
The accessories list is the real story here. You get an air frying basket, air rack, baking tray, crumb tray, bacon tray, cookie sheet, two dehydrating racks, a 2-in-1 dehydrator and steak tray, a rotisserie spit with forks and handle, tongs, a silicone mat, two oven mitts and a hardcover cookbook with 60 recipes. In daily use, that means sweet potato wedges go in the basket, whole potatoes go on the rack over the crumb tray to catch drips, and leftover roasted cubes get reheated on the baking tray. The rotisserie setting spins meat on the included spit so it bastes in its own juices — handy if you want a chicken roasting while potatoes crisp underneath in the same session.
The 21 presets and digital LED controls take the guesswork out of timing, and the top temperature reaches 500°F, which is genuinely useful for getting caramelized edges on sweet potato rounds. Kalorik also states it uses 77% less energy than a traditional oven, which is the kind of claim that matters when you're running a long roast.
The trade-off is size and commitment. At about 21.3 pounds and roughly 12.4 by 15.55 by 13.54 inches with a French-door design, it wants real counter space and a nearby outlet — the cord is 34 inches. It's a stainless steel machine that rewards people who cook in volume. If you mostly make one sweet potato at a time, this is more oven than you need. It carries a one-year warranty in the U.S. and Canada.
Strictly speaking, this isn't an air fryer — it's a replacement grill plate built for Ninja units, and it's the pick for anyone who already owns one and finds the stock crisper plate annoying. GXF sizes it at 8.2 inches and lists compatibility with the Ninja AF100, AF101, AF150 and AF161 air fryers, plus Ninja Foodi pressure cookers and any other air fryer that takes an 8.20 by 8.20 inch crisper plate. Measure your basket's inner diameter before ordering; GXF says so twice in its own notes, and that's the single biggest reason these get returned.
What you're buying is a round, black, non-stick metal plate with a handle, and the handle is the point. Lifting a hot plate out of a deep basket with tongs is the worst part of air frying, and a built-in grip solves it. The coating is a double-layer enameled non-stick finish, and GXF describes it as dishwasher safe — though the brand also warns against abrasive pads and metal scouring balls, and against washing it while it's still too hot. Three rubber bumpers are included to keep the plate from rattling around, along with a cleaning cloth.
On the sweet potato front, GXF specifically mentions using the tray to bake sweet potatoes and other foods, and it also lists oven and pressure-cooker use, plus sauteing, grilling, frying and baking for pizza, fries, steak, chicken wings and vegetables. Realistically, this plate is best for sweet potato cubes and rounds — pieces small enough to sit flat and get air moving around them. A whole sweet potato on a flat plate won't crisp as evenly as it would on a rack, because the underside stays in contact with the surface.
The trade-off is that it's a part, not an appliance. It only makes sense if the dimensions match what you already own, and it's a single-item package: one grill plate, one cloth, three bumpers. Buy it to fix a specific annoyance, not to gain new cooking modes.
The Chefman is the sensible small-kitchen answer. It's a 3.5-quart digital air fryer with a flat basket design that Chefman says holds 40% more food than a traditional round basket without adding bulk. It measures 8.5 inches deep, 10 inches wide and 13.75 inches tall, weighs 7.9 pounds, and runs on 1200 watts at 120 volts. Temperature is adjustable from 175°F to 400°F, and there's a 60-minute integrated timer with automatic shutoff.
For sweet potatoes, the flat basket is the feature that earns its keep. A flat floor means cubed sweet potatoes spread out in a single layer instead of piling up in a narrow well, and a single layer is what gets you browning rather than steaming. The wide temperature band helps too: lower settings around 175°F to 200°F are gentle enough for reheating or finishing, while the top end near 400°F is what you want for sweet potato fries and wedges. The touch controls are digital, and Chefman notes it can bake, grill or roast, not just fry.
Cleanup is straightforward — the non-stick basket is dishwasher safe, and Chefman's own advice is to stick to soft sponges and cloths when hand washing. The unit is cETL approved and comes with a one-year assurance from Chefman.
The trade-off is capacity and footprint in the other direction. It's a compact single-basket machine, so it's built for one or two people, and a family-sized batch of sweet potato fries will need to go in two rounds. There's no rotisserie, no dehydrator and no second rack. If you want a small, tidy appliance that does sweet potato cubes and fries reliably and stows easily, that's a fair trade. If you're feeding four, it isn't.
The Kreiaoer is the one I'd point a curious first-timer toward, because the whole design is built around being able to see what's happening. The cooking pot is 4.2 liters, listed as 4.44 quarts, made of borosilicate glass, and it gives a full 360-degree view of the food as it cooks. That sounds like a gimmick until you've stood over an opaque basket opening the drawer every three minutes to check whether your sweet potato cubes are browning.
It runs on 1200 watts with rapid heating, offers a temperature range of 176°F to 392°F and up to 60 minutes of cooking time, and controls everything through a touchscreen. There are eight presets: French fries, roast, chicken wings, egg tarts, grilled fish, sweet potatoes, grilled shrimp and steak. A sweet potato preset is unusual at this price tier of design, and it's a genuinely convenient starting point for someone who doesn't yet know their own timing.
The stainless steel grill inside the pot supports hot-air circulation, and the removable glass pot is dishwasher safe. It weighs 7.1 pounds and measures about 9.84 by 9.84 by 12.6 inches, so it occupies roughly the same counter real estate as the Chefman.
The trade-off is that glass is glass. It's heavier than a coated metal basket, you'll want to be careful handling a hot pot, and the 4.44-quart capacity puts it in the small-to-medium range — fine for two or three portions of sweet potato wedges, tight for a crowd. It's also a single-grill setup, so there's no rack for stacking. What it does well is make the cooking process visible and simple, and for sweet potatoes specifically, that visibility is worth more than it sounds.
We compared the published specifications and feature sets of each product — capacity, wattage, temperature range, controls, accessories and materials — and weighed how those details play out for sweet potato cooking specifically: whole potatoes, cubes and fries. This ranking is our independent editorial opinion. No brand paid for placement, and no manufacturer saw this list before publication.
FAQ
how to air fryer sweet potatoes
Pick your cut based on the appliance. Whole sweet potatoes do best on a rack in a large oven-style unit like the Kalorik, where air reaches all sides. Cubes and fries want a flat single layer in a basket like the Chefman or on a plate like the GXF. Set your temperature, and use the preset if your unit has one.

how to air fryer sweet potato fries
Fries need space and heat. Use the top of your range — 400°F on the Chefman, 392°F on the Kreiaoer, up to 500°F on the Kalorik. Cook in batches rather than crowding, and use a basket or rack so hot air moves underneath. The Kalorik's air frying basket and the GXF plate both work well here.
how to air fryer sweet potato whole
Whole potatoes are the bulkiest job. The Kalorik's 26-quart cavity with an air rack is the easiest fit, and its 500°F ceiling helps with caramelization. If you're using a smaller unit, choose smaller potatoes and expect a longer cook. The GXF plate is better suited to cubes than whole potatoes, since a flat surface blocks airflow underneath.
