• home style Microwave Potato Chip — best for oil-free microwave chips and thin sliced snacks; pick this if you want to slice sweet potatoes yourself with the included handheld slicer and crisp them in the microwave instead of an air fryer.
• DASH Tasti-Crisp Express Air — best for everyday countertop air frying of sweet potato fries and frozen snacks; pick this if you want a compact 2.6-quart basket, a 400°F max temperature and auto shut-off in a small footprint.
• HuidTews Glass Airy Fryer — best for watching your sweet potato fries cook without opening the basket; pick this if a 360° viewable borosilicate glass bowl and 8 preset modes (including sweet potatoes) appeal to you.
• ForconMed Potato machine — best for spiral-cut sweet potato fries and tornado potatoes; pick this if you want a manual stainless steel slicer with a suction cup base that holds itself steady while you crank.
• siohdagu 3.81Qt — best for larger glass-bowl batches with dishwasher-safe cleanup; pick this if you want a 3.81-quart nonstick glass pot with 8 presets and a 31.5-inch cord for flexible counter placement.
This is not an air fryer at all, and I want to be upfront about that, because searching for "air fryer sweet potato fries" will absolutely surface products like this. The home style Microwave Potato Chip is a two-piece kit: a microwave chip rack and a handheld slicer. You slice sweet potatoes thin, blot them dry, stand the slices upright in the rack without overlapping, and microwave them following the included instructions. No oil goes on before microwaving — the sheet is explicit about that.
So why is it in a guide about sweet potato fries? Because the hardest part of sweet potato fries is the slicing. Sweet potatoes are dense and oddly shaped, and uneven slices are the number one reason you get burnt tips and raw centers. The handheld slicer in this kit solves that problem for a very small outlay of effort, and the rack is sized at roughly 8.75" x 8", which fits a standard microwave turntable without drama.
Who is it for? In my opinion, this is for the person in a small apartment, dorm or office kitchen who wants a crunchy sweet potato snack and either doesn't own an air fryer or doesn't want to run one for a single serving. It's also a genuinely good fit for anyone feeding kids an after-school snack, or prepping thin sweet potato slices to finish in an air fryer later.
Beyond sweet potatoes, the sheet lists potatoes, apples, bananas, zucchini and other firm fruits and vegetables. That flexibility matters more than it sounds — a banana chip and a zucchini chip have completely different moisture levels, so the "cooking times may vary by microwave, food type, and slice thickness" note isn't boilerplate, it's the actual reality of microwave chip making.
The trade-off is real: microwave chips are finicky. You're working in 30-second increments, and slices that touch each other steam instead of crisping. The rack is BPA-free plastic and measures 8 x 8 x 1.7 inches, weighing 6.4 ounces, so it's light and easy to store — but it's a single-purpose tool that rewards patience. If you want a set-it-and-forget-it fry, this isn't it.
DASH Tasti-Crisp Express Air
Here's my pick, and I'll explain the reasoning rather than just asserting it. The Tasti-Crisp Express Air is a 2.6-quart compact air fryer with a 1000-watt heating element, a 400°F max temperature setting, and AirCrisp hot-air circulation technology. It uses a mechanical knob and touch controls, has a cool-touch handle, and shuts off automatically.
The nonstick basket with a PTFE inner material and aluminum/polypropylene construction means fries release cleanly and cleanup is a rinse rather than a scrub. The auto shut-off and cool-touch handle are the kind of features you stop noticing until the day you're juggling a hot basket and a hungry kid — then they matter a lot.
Physically it's 10.7"D x 8.7"W x 11.3"H and 6.1 pounds, which is small enough to live on a countertop permanently or tuck into a cabinet in a small kitchen. It runs on 110 volts and draws 1000 watts. Recommended uses on the sheet are bake, dehydrate, reheat and roast, and it ships with an instruction manual and recipe guide.
The main trade-off: capacity and control granularity. You get a knob, not a digital display, so you're setting temperature and time by feel rather than to the degree. And 2.6 quarts is genuinely small. But for a single person or a couple making a side of sweet potato fries alongside dinner, the simplicity is the point — fewer settings means fewer ways to get it wrong.
The HuidTews Glass Airy Fryer is a 3.81-quart machine with a 1200-watt element and a borosilicate glass inner bowl, which gives it a genuinely different personality from a basket-style fryer. The 360° viewable design means you watch your sweet potato fries brown from any angle without pulling the basket out and dumping heat.
That visibility is more useful than it sounds for sweet potato fries, because they go from "not quite done" to "carbonized" faster than white potatoes. The sheet notes the obvious reason this matters: opening the appliance mid-cook causes heat loss, which leads to uneven cooking and longer times.
The control side is a touchscreen with digital display, adjustable from 176°F to 392°F and 1 to 60 minutes. There are 8 preset modes with default reference temperature and time, and sweet potatoes is one of them — along with french fries, grilled fish, grilled shrimp and steak. I'd treat the sweet potato preset as a starting point and adjust from there, since sweet potato fry thickness varies so much.
Capacity is 3.81 quarts, which the sheet positions as enough for a small family or a group of friends without multiple batches. The build mixes PP, borosilicate glass and stainless steel, and it includes a grill insert and an English manual. It's 9.84"D x 9.84"W x 12.6"H and weighs 8.4 pounds, running on 110 volts.
The trade-off: glass. It's heavier than a comparable nonstick basket, and while borosilicate is tough, it's still glass and deserves careful handling. The 392°F max is also just a hair under the 400°F that many sweet potato fry recipes assume. If you want maximum browning, that small gap is worth knowing about.
ForconMed Potato machine
For sweet potato fries, the appeal is the cut itself. Spiral-cut sweet potatoes give you long, curly fries with more surface area, which means more edges to crisp. The sheet lists potatoes, radishes, carrots, cucumbers, onions and sweet potatoes among the things it handles, and it comes with 50 bamboo BBQ skewers, which is exactly what you'd want for tornado potatoes on a skewer.
The suction cup base is the feature I'd highlight. Spiral slicers are famously annoying when they slide across the counter mid-crank, and the sheet makes a point of saying you don't need a second person to hold it down. It also ships with installation tools and replacement blades, so you're not stuck when the blade dulls.
It measures 12.6"L x 4.53"W x 5.32"H and weighs about 1.5 kg, so it's a drawer or cabinet item rather than a countertop resident. The sheet also carries a clear safety warning: keep your fingers off the blade during operation. Take that seriously — the 304 stainless blade is sharp by design.
The trade-off is obvious and worth stating plainly: this is a prep tool, not a cooking appliance. You still need an air fryer, oven or microwave to actually cook the sweet potato. It's also hand-cranked, so it's slower and more effortful than an electric slicer. If you want spiral fries without buying an electric spiralizer, this is a reasonable manual route.
The siohdagu 3.81Qt is the closest thing here to a direct sibling of the HuidTews unit, sharing the 3.81-quart borosilicate glass bowl, 1200 watts and touch controls — but the differences matter if you're choosing between them.
Start with the presets. This one lists 8 modes: french fries, roast, chicken wings, egg tarts, grilled fish, sweet potatoes, grilled shrimp and steak. That's a broader preset spread than the HuidTews list, and sweet potatoes is again included, which makes it a sensible starting point for fries.
Temperature and time range: 176°F to 392°F, and 1 to 60 minutes. Same ceiling as the HuidTews, so the same caveat applies — if your sweet potato fry method needs a full 400°F, neither glass unit goes quite that high. The 1200-watt rapid-heating design cuts preheating time, which is a real convenience when you're cooking a small side.
Where this one pulls ahead for me is cleanup and placement. The sheet specifies a nonstick coating and a dishwasher-safe pot, so food slides off and the bowl can go straight into the dishwasher. The 31.5-inch power cord is a genuinely thoughtful detail — it lets you position the unit on the counter without hunting for an outlet directly behind it, and it reduces cord clutter.
The stainless steel grill insert lets hot air circulate evenly around the food, which is the mechanical reason fries brown on all sides rather than just the top. It's 9.84"D x 12.6"W x 9.84"H and weighs around 8.4 pounds, running on 110 volts. Included components are the air fryer and the grill.
The trade-off: same as its glass cousin — 392°F max and a glass bowl that's heavier than a nonstick basket. And like most glass-bowl air fryers, you're trading some raw browning power for the ability to see exactly what's happening. In my opinion, that's a fair trade if you're the type who hates guessing.
How We Picked
how to air fryer sweet potato fries
Slice the sweet potatoes into even strips, pat them dry, and cook them in a single layer with space between pieces so hot air can circulate. The DASH Tasti-Crisp Express Air uses AirCrisp hot-air circulation with a 400°F max temperature, and the glass units from HuidTews and siohdagu offer preset sweet potato modes as a starting reference. Don't add oil before microwaving if you're using the home style microwave rack.

Even slices, dry surfaces, and no crowding are the three levers. The home style kit's handheld slicer helps with even thickness, and its instructions call for blotting slices dry and arranging them upright without overlapping. In an air fryer, the stainless steel grill insert on the siohdagu unit lets hot air circulate evenly around the food, which is what produces browning on all sides.
how long to air fryer sweet potato fries
Timing depends on slice thickness and your machine, which is why the home style kit notes that cooking times vary by microwave, food type and slice thickness. The glass air fryers here allow you to set 1 to 60 minutes, so you have room to work in short increments and check progress. Start shorter than you think and add time.
how to get air fryer sweet potato fries crispy
Use the highest temperature your unit allows — 400°F on the DASH, 392°F on the HuidTews and siohdagu — and resist the urge to open the appliance during cooking. The HuidTews sheet specifically warns that opening during cooking causes heat loss, which leads to uneven cooking and longer times. Its 360° viewable glass bowl lets you monitor progress without that heat loss.
