How to Air Fry Mushrooms

Clean mushrooms with a damp paper towel rather than washing under water — mushrooms are spongy and absorb water which makes them steam instead of roast. Remove the stems if cooking whole mushrooms (the stems cook at a different rate). For sliced mushrooms, ¼–⅜ inch slices give a good balance of browning and texture. For whole button or cremini mushrooms, use similarly sized ones so they cook evenly — sort by size and separate very small ones from large ones if needed. Pat dry after cleaning.

Toss mushrooms in ½–1 tsp oil and season with salt and pepper. Preheat the air fryer to 400°F for 2 minutes. Spread in a single layer — this is especially important for mushrooms, which release more moisture than most vegetables. Cook for 4–5 minutes, then shake the basket. At this point, you will notice moisture has been released from the mushrooms. Continue cooking for another 4–6 minutes until the liquid has evaporated and the mushrooms are golden with slightly caramelized edges. The first 4–5 minutes are mostly steaming; the second half is browning.

Mushrooms absorb and amplify flavors very effectively. Before cooking: garlic powder, thyme, and rosemary (toss in); soy sauce (1 tsp per 2 cups — adds umami and helps browning); smoked paprika (add depth without adding moisture). After cooking: fresh minced garlic tossed in and returned to the air fryer for 2 minutes; balsamic vinegar (1 tsp after cooking gives a sweet-acidic finish); grated parmesan (added in the last 2 minutes for a savory crust); fresh herbs — parsley, thyme, chives. Garlic added at the start will burn before the mushrooms are done; always add fresh garlic at the end.

Portobello caps air fry well at 390°F for 10–12 minutes. Remove the gills with a spoon if you prefer (the gills are edible but can discolor sauces). Brush both sides lightly with oil. Cook gill-side up first for 5 minutes, then flip and cook for another 5–7 minutes. For stuffed mushrooms: remove the stem and gills, fill with a cheese and breadcrumb mixture, and air fry at 375°F for 8–10 minutes until the filling is golden and the cap is tender. Stuffed mushrooms are done when the filling is bubbly and the cap has softened significantly.

How long do you air fry mushrooms?

Sliced mushrooms: 8–10 minutes at 400°F (205°C), shaken once at 5 minutes. Whole button or cremini mushrooms: 10–14 minutes depending on size. Portobello caps (whole): 10–12 minutes at 390°F. Mushrooms release significant moisture — do not overcrowd or they will steam rather than roast. Toss in ½–1 tsp oil and season before cooking. The ideal result is golden-brown edges and a concentrated, savory flavor. Adding garlic and herbs in the last 2 minutes prevents burning.

Do mushrooms need oil in an air fryer?

A small amount of oil is strongly recommended for mushrooms. Mushrooms have very porous cell structures and absorb oil quickly — ½ teaspoon per cup of mushrooms is enough to coat them. Without oil, mushrooms air-fry to a dry, slightly chewy texture without browning. With a light coat of oil, they develop golden-brown caramelized edges and a deeper savory flavor. If avoiding oil, add a splash of soy sauce or balsamic vinegar instead — the sugars in these liquids promote browning and add flavor.
