First, I gently wash the mushrooms under cold water and dry them really well—no one wants soggy mushrooms. Then I halve or quarter them, depending on size. Keeping them similarly sized helps them all cook evenly and develop those nice crispy edges.
Once they’re dry, I toss them in a large bowl with olive oil, garlic and onion powder, Worcestershire sauce, and salt. The Worcestershire sauce is my secret weapon—it brings a rich, savory depth that pairs beautifully with mushrooms.
I preheat the air fryer to 400°F (around 200°C). While it heats, I arrange the mushrooms in a single layer in the basket—no overcrowding. If they’re on top of each other, they steam instead of crisp. For smaller air fryers, I work in batches.
I cook them at 400°F for 10 minutes, then give the basket a good shake to rotate the mushrooms. Another 5 minutes or so gets them nice, browned, and juicy. I always keep an eye on them near the end so they don’t burn.
These mushrooms are best enjoyed right out of the air fryer, while the edges are crispy and the insides still tender. I love tossing in a handful of chopped parsley for brightness, or serving alongside grilled meat, tossed in salads, or even on toast.
