Quick Answer
The best air fryer for kale chips is the Cuisinart TOA-70, because kale needs flat single-layer surface area far more than it needs basket volume -- a 3-to-4-ounce bag of torn leaves can fill a round basket before it ever fills that basket's rated quart capacity. Dry leaves thoroughly, massage with a light coat of oil, spread in a true single layer, and cook at 350-375°F for 4 to 5 minutes, checking every minute near the end since kale can go from crisp to burnt in under a minute. According to USDA FoodData Central, raw kale delivers about 93.4 mg of vitamin C and 390 mcg of vitamin K per 100 grams.
"Best air fryer for kale chips" searches usually land on reviews that compare quart capacity, wattage, and presets -- the same specs that matter for chicken wings or frozen fries. Kale chips break that comparison. A quart rating measures how much volume a basket holds, but torn kale leaves are bulky, irregular, and need to lie in a true single layer with no leaf resting on another -- which means the limiting factor is floor space, not volume. A compact basket that handles a pound of wings with room to spare can fill up completely with a single modest bag of kale.

Top 4 Best Air Fryers for Kale Chips
1. Cuisinart TOA-70 Air Fryer Toaster Oven — Best Overall for Kale
Kale's real constraint is single-layer floor space, and the Cuisinart TOA-70's flat oven-style rack has the most of it in this lineup -- with no perforated mesh basket floor curving up at the edges and no round shape wasting corner space. Running two racks (upper and lower, rotated partway through) lets a full bag of kale cook in two true single layers instead of three or four cramped basket batches.
It also functions as a full convection oven, toaster, and broiler, at the cost of a larger countertop footprint and a higher price than a basket-style unit.
Pros: Most true single-layer area of the four, no mesh floor to trap leaf stems, doubles as a full oven
Cons: Big footprint, pricier than a basket model
Best For: A full bag of kale cooked in the fewest batches
2. Ninja Foodi DZ201 8-Quart Dual Zone — Best for Doubling a Batch
Most dual-zone picks in this series earn their spot by running two different foods at once. For kale, the Ninja Foodi DZ201 earns it differently: both 4-quart square baskets can run the exact same single-layer batch of kale at the exact same setting, in parallel, which effectively doubles the single-layer footprint of a single basket unit without needing a second device.
Square baskets also beat a tapered round shape for laying torn, irregular leaves flat. The trade-offs are a larger footprint and a higher price than a single-basket model.
Pros: Two zones double single-layer capacity at once, square baskets lay leaves flatter than round ones
Cons: Large footprint, pricier than a single-basket unit
Best For: Getting a full bag of kale done in one cooking cycle instead of several
3. COSORI Pro LE 5.8-Quart — Best Single-Basket Option
Among single-basket units, the COSORI Pro LE's wide square basket floor holds a noticeably larger true single layer of torn kale than a similarly rated round basket would, since a square shape doesn't waste space tapering inward at the bottom. It's a solid middle ground for a lunch-size batch without the footprint of a dual-rack or dual-zone unit.
Nine one-touch presets, a PFAS-free ceramic basket, and quiet under-55-dB operation make it a strong everyday pick well beyond kale chips.
Pros: Square basket beats a round one of the same rating, PFAS-free ceramic, dishwasher-safe, quiet
Cons: Still a single zone, so a full bag still needs 2+ batches
Best For: Most home cooks making a single-serving-to-lunch-size batch
4. Instant Vortex Mini 2-Quart — Best for a Small Handful Only
To be direct about the honest trade-off: the Instant Vortex Mini is the weakest match for kale chips in this guide, even though it's a fine small air fryer generally. Its tiny round base holds only a handful of torn leaves in a true single layer, so a standard 3-to-4-ounce bag of kale needs three or four separate batches back to back -- a real time cost that larger units don't have.
It still works fine for a single small snack-size portion, and its small size and low price make it an easy second unit rather than a main pick for kale specifically.
Pros: Fast to heat, affordable, small footprint
Cons: Smallest single-layer footprint of the four, needs the most batches per bag
Best For: A single small snack portion, not a full bag at once
What Makes an Air Fryer Good for Kale Chips?
Volume Isn't the Spec That Matters
Quart capacity describes how much space is inside a basket, but kale chips are limited by a different measurement: how much flat, non-overlapping floor area a single layer of torn leaves needs. Kale leaves are light, bulky, and irregularly shaped compared to denser foods like wing pieces or sliced vegetables, so the same weight of kale takes up dramatically more single-layer footprint than almost anything else in this site's buying guides. A basket rated highly enough to handle a full pound of wings can still fill up completely with a modest 3-to-4-ounce bag of kale.
Why the Burnt-Versus-Chewy Window Is So Narrow
Kale's thin leaf structure and low moisture content mean there's very little buffer between undercooked and burnt -- multiple recipe developers independently describe a batch going from perfectly crisp to scorched within about a minute of inattention. That's a much narrower margin than thicker produce like broccoli or zucchini gets. Recipes online disagree sharply on temperature as a result, with recommendations ranging from a gentle 275°F up to 400°F; a middle-ground 350-375°F for 4-5 minutes, checked every minute near the end, is the safer approach for most machines.
Moisture and Crowding Cause the Same Failure
Leaves that aren't completely dry after washing trap residual water that steams instead of crisping -- and that trapped moisture also keeps oil and salt from sticking evenly. An overcrowded basket causes a related problem: overlapping leaves shield each other from hot air, so they stay chewy longer, then brown unevenly and scorch at the exposed edges once the batch finally catches up. Thorough drying and a genuine single layer solve both issues at once.
How to Air Fry Kale Chips
Wash kale thoroughly and pat it completely dry, or spin it dry in a salad spinner -- any leftover moisture prevents proper crisping. Remove the thick center stems and tear the leaves into 2-to-3-inch pieces. Drizzle with a small amount of oil and massage it into the leaves by hand for 1-2 minutes until every piece is lightly and evenly coated, then season.
Arrange the kale in the basket or on the rack in a single layer with no leaves touching or overlapping, working in batches if your unit's footprint doesn't fit the whole bag at once. Air fry at 350-375°F for 4 to 5 minutes, shaking the basket or checking the rack halfway through, then watching closely minute by minute near the end. Chips are done when they're crisp and slightly browned at the edges; they'll continue to firm up as they cool for a minute or two before serving.
Frequently Asked Questions
What is the best air fryer for kale chips?
The best air fryer for kale chips is the Cuisinart TOA-70, since its flat oven-style racks give torn kale leaves the widest true single-layer footprint of any model in this guide -- and kale needs that footprint far more than most foods, since a single 3-to-4-ounce bag of torn leaves can fill a round basket before it ever fills that basket's quart rating. A single layer at 350-375F for 4-5 minutes, shaking or checking every minute near the end, keeps leaves crisp instead of burnt.
Why do my kale chips burn in the air fryer?
Kale leaves are thin with very little moisture compared to most vegetables, so the window between undercooked-chewy and burnt is much narrower than it is for something like broccoli or zucchini -- several recipe developers independently describe kale going from crisp to burnt within about a minute of inattention. The two biggest causes are leaves that weren't dried thoroughly after washing (residual water steams instead of crisping, then overcooks trying to catch up) and an overcrowded basket, where overlapping leaves shield each other from hot air until a late, uneven burst of browning scorches the exposed edges.
What temperature should I air fry kale chips at?
Recipes online disagree more on this than almost any other air fryer food, ranging from a gentle 275F up to 400F. A middle-ground 350-375F for 4-5 minutes, checked every minute in the final stretch, works for most air fryers and matches what this site's own kale chips recipe uses. If your air fryer runs hot or your leaves are cut smaller, starting at the lower end of that range and adding time is safer than starting high and losing a batch to burning.
Why does my air fryer's quart capacity not match how much kale it actually holds?
A quart rating measures basket volume, but kale chips need surface area, not volume. Torn kale leaves are bulky and irregular, and a true single layer -- no leaf resting on top of another -- takes up far more floor space per ounce than small, flat, or dense foods like shrimp or sliced vegetables. A 5.8-quart round basket can fill up with a single 3-to-4-ounce bag of kale well before it reaches its rated capacity, which is why flat oven-style racks or multiple baskets handle kale better than their quart numbers alone would suggest.
Is kale healthier when air fried instead of deep fried?
Air frying uses a light coating of oil -- typically a drizzle massaged over the leaves -- instead of submerging them in an oil bath, so the finished chips carry far less added fat than a deep-fried version while still crisping up. According to USDA FoodData Central, raw kale itself is already a dense source of nutrients: about 93.4 mg of vitamin C and 390 mcg of vitamin K per 100 grams, roughly 104% and 325% of the respective daily values, which air frying's shorter, lower-oil cook preserves better than deep frying's longer oil-bath exposure.
Final Recommendation
For most people making kale chips regularly, the Cuisinart TOA-70 is the best air fryer for the job -- its flat racks hold the single-layer footprint kale actually needs, not just a high quart number. If you'd rather keep a basket-style unit, the Ninja Foodi DZ201's two zones let you run double the footprint in one cycle. Whichever model you use, the fix for burnt or soggy kale chips is the same everywhere: dry the leaves completely, coat them lightly and evenly, keep them in a genuine single layer, and watch the last minute closely.
