Quick Answer
The best air fryer for mushrooms is the Cuisinart TOA-70, whose flat rack gives a pound of sliced mushrooms enough single-layer room to crisp instead of steaming in their own released liquid. Mushrooms are about 92% water (USDA FoodData Central), so a basket that looks packed raw will shrink to roughly half that volume once cooked -- don't judge a batch by how full it looks going in. Cook at 375-400°F for 8-10 minutes, shaking halfway, and keep whole caps and sliced pieces in separate batches since they finish at different rates. Only UV-exposed mushrooms carry meaningful vitamin D; untreated button mushrooms have very little.
"Best air fryer for mushrooms" searches tend to land on reviews built around quart capacity and wattage -- specs that matter plenty for chicken wings or frozen fries, but mislead for mushrooms specifically. Mushrooms are mostly water, so the raw volume you load into a basket has almost nothing to do with the cooked volume you pull back out. A basket that looks completely full of sliced mushrooms before cooking can look barely half full once it's done -- the reverse of what most people expect, and the reverse of what a food like kale does in the same basket.
Quick Comparison: Best Air Fryers for Mushrooms

Top 4 Best Air Fryers for Mushrooms
1. Cuisinart TOA-70 Air Fryer Toaster Oven — Best Overall for Mushrooms
Mushrooms release a lot of liquid as they cook, and a deep mesh basket lets that liquid pool at the bottom where it mixes with oil and keeps the lowest layer steaming. The Cuisinart TOA-70's flat oven-style rack sidesteps that entirely -- no perforated floor for liquid to collect on, and enough width to spread a full pound in a true single layer so every piece browns instead of braising in its own runoff.
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: No mesh floor for liquid to pool on, most single-layer room of the four, doubles as a full oven
Cons: Big footprint, pricier than a basket model
Best For: A full pound of mushrooms browned in the fewest batches
2. Ninja Foodi DZ201 8-Quart Dual Zone — Best for Mixed Sizes
Whole button mushrooms and halved portobello caps don't cook at the same rate -- recipes commonly run whole caps around 10-12 minutes and sliced or smaller pieces closer to 5-7 minutes at a higher temperature. Forcing both into one basket means one or the other finishes wrong. The Ninja Foodi DZ201's two independent 4-quart zones let you run whole and sliced mushrooms side by side on their own settings at the same time, instead of babysitting one basket through two different timers.
Square baskets also beat a tapered round shape for spreading irregular pieces flat. The trade-offs are a larger footprint and a higher price than a single-basket model.
Pros: Two zones handle whole and sliced mushrooms on separate timers at once, square baskets lay pieces flatter than round ones
Cons: Large footprint, pricier than a single-basket unit
Best For: A mixed batch of whole caps and sliced pieces in one cooking cycle
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 sliced mushrooms than a similarly rated round basket, since a square shape doesn't waste space tapering inward at the bottom -- useful given how much that raw volume is about to shrink. It's a solid middle ground for a full pound 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 mushrooms.
Pros: Square basket beats a round one of the same rating, PFAS-free ceramic, dishwasher-safe, quiet
Cons: Still a single zone, so whole and sliced mushrooms still need separate batches
Best For: Most home cooks making a standard pound-sized batch
4. Instant Vortex Mini 2-Quart — Best for a Garnish-Size Portion Only
To be direct about the honest trade-off: the Instant Vortex Mini is the weakest match for mushrooms in this guide, even though it's a fine small air fryer generally. Its tiny round base looks full with a modest handful of sliced mushrooms raw -- but since mushrooms are roughly 92% water, that same batch collapses to barely enough for a single garnish portion once it's done, not the side dish it appeared to be going in.
It still works fine for a quick single-serving topping, and its small size and low price make it an easy second unit rather than a main pick for mushrooms specifically.
Pros: Fast to heat, affordable, small footprint
Cons: What looks like a full basket raw shrinks to a small fraction cooked, needs the most batches for a real portion
Best For: A quick garnish-size topping, not a full side dish
What Makes an Air Fryer Good for Mushrooms?
Why a Full Basket Isn't What It Looks Like
According to USDA FoodData Central, raw white mushrooms are about 91.8 grams water per 100 grams -- roughly 92% water by weight. Almost all of that releases as steam during cooking, which is why a basket packed edge-to-edge with raw mushrooms can shrink to about half that volume once they're done. That's the opposite problem from bulky, low-moisture foods like torn kale, which need more single-layer room than their weight suggests, not less. Loading a basket based on how full it looks raw, rather than how much cooked mushroom you actually want, is the most common reason people either under-fill a batch or crowd it without meaning to.
Whole vs. Sliced Cook at Different Rates
Mushroom size and shape drive cook time more than almost any other variable. Whole button or cremini caps commonly run about 10-12 minutes at 375°F, while sliced or halved pieces cook faster -- often done in 5-7 minutes at a higher 400°F, since more surface area is exposed to hot air at once. Mixing whole and sliced pieces in the same basket means one finishes before the other releases its water and browns, so keeping pieces a consistent size (or running whole and sliced as separate batches) matters more than chasing one universal timer.
Crowding Traps the Water Mushrooms Release
A crowded basket compounds the moisture problem: released liquid pools underneath overlapping pieces instead of evaporating, so the mushrooms on the bottom steam rather than crisp. A true single layer with visible gaps between pieces lets that steam escape upward instead of condensing back onto the food, which is the main reason "soggy air fryer mushrooms" is such a common complaint even though the method itself works well.
Vitamin D Is a Label Question, Not a Mushroom Guarantee
Mushrooms are often marketed as a vitamin D source, but that's only true of mushrooms deliberately exposed to UV light during growing. Figures compiled from USDA data by the Mushroom Council put a 90-gram serving of UV-exposed white mushrooms at about 23.6mcg of vitamin D (118% of the Daily Value) and an 80-gram serving of UV-exposed crimini at about 25.52mcg (128% DV). Untreated mushrooms of the same variety contain only a trace amount, so the vitamin D claim on a package is worth checking rather than assuming.
How to Air Fry Mushrooms
Wipe mushrooms clean with a damp cloth or paper towel rather than soaking them, since mushrooms absorb water like a sponge and extra moisture only adds to what they'll release on their own. Trim the stems, then either leave caps whole or slice them into even pieces -- just keep whole and sliced mushrooms in separate batches since they cook at different rates. Toss with a small amount of oil and seasoning.
Arrange in a true single layer with visible space between pieces, working in batches if the full amount doesn't fit without overlapping. Air fry whole caps at 375°F for 10-12 minutes, or sliced pieces at 400°F for 5-7 minutes, shaking or flipping halfway through. Mushrooms are done when they're golden brown and have released most of their visible liquid; they'll firm up slightly more as they cool for a minute before serving.
Frequently Asked Questions
What is the best air fryer for mushrooms?
The best air fryer for mushrooms is the Cuisinart TOA-70, since its flat oven-style rack gives a pound of sliced mushrooms enough single-layer room to crisp instead of steaming in their own released liquid. Cook at 375-400F for 8-10 minutes, shaking or flipping halfway, and keep whole caps separate from sliced pieces since they finish at different rates.
Why do my mushrooms steam instead of crisping in the air fryer?
Mushrooms are about 92% water according to USDA FoodData Central, so a crowded basket traps that released liquid at the bottom instead of letting it evaporate, and the mushrooms steam in it rather than browning. A true single layer with space between pieces lets the water vapor escape instead of pooling.
Why does a full basket of raw mushrooms look mostly empty after cooking?
Because mushrooms are roughly 92% water by weight (USDA FoodData Central), most of their raw volume cooks away as steam. A basket that looks packed before cooking can shrink to about half that volume once the water releases and the mushrooms collapse -- the opposite problem from bulky, low-moisture foods like torn kale, which need more single-layer room than their weight suggests, not less.
Do mushrooms have vitamin D?
Only mushrooms deliberately exposed to UV light carry meaningful vitamin D. Figures compiled from USDA data by the Mushroom Council put a 90-gram serving of UV-exposed white mushrooms at about 23.6mcg of vitamin D (118% of the Daily Value) and an 80-gram serving of UV-exposed crimini at about 25.52mcg (128% DV). Untreated mushrooms of the same variety contain only a trace amount, so check the label if vitamin D is the reason you're buying them.
Final Recommendation
For most people cooking mushrooms regularly, the Cuisinart TOA-70 is the best air fryer for the job -- its flat rack gives released liquid somewhere other than a mesh floor to pool, and its single-layer room doesn't punish you for how much a batch is about to shrink. If you regularly mix whole caps with sliced pieces, the Ninja Foodi DZ201's two independent zones solve that timing mismatch directly. Whichever model you use, the fix for soggy or unevenly cooked mushrooms is the same everywhere: keep pieces a consistent size, give them real single-layer space, and judge the batch by the cooked result, not by how full the basket looked going in.
