Prep
Wipe the caps clean with a damp cloth — never rinse under water as mushrooms absorb moisture. Remove the stem and use a spoon to scrape out the dark gills (optional but reduces bitterness and makes room for fillings). Brush both sides with olive oil and season with salt, pepper, and garlic.
Temperature and Time
Place caps gill-side up in the basket. The cap will soften and shrink, and the edges will caramelize. Use the whole portobello cap (4–5 inch, ≈100 g) preparation. Set the air fryer to 375°F (190°C); the starting range is 8–12 minutes. Turn or shake at about 5 minutes as appropriate for the food. Check at the lower end and continue as needed; thickness, load and the appliance affect the actual time.Follow the preparation and texture checks for this food.
Filling Ideas
Spinach and feta, Italian sausage and mozzarella, quinoa and sun-dried tomatoes, or a classic garlic-herb cream cheese all work well as fillings. Press fillings in firmly so they stay in place during cooking.
Serving
Serve as a vegetarian main course, use as a burger substitute in a bun, or slice and add to pasta, grain bowls, or salads. A drizzle of balsamic glaze just before serving adds a complementary sweet acidity.
