These stuffed mushrooms cooked in the air fryer work great as party nibbles or tasty treats. The crimini caps filled with cheese, vibrant peppers, and herbs turn beautifully golden and soft when air-fried.
Key Ingredients
- Crimini mushrooms: Try to find ones roughly 2 inches across
- Mozzarella and Parmesan: They bring creaminess and rich flavor
- Bell peppers and onions: Add texture and natural sweetness
- Leafy herbs: Try cilantro or parsley
- Basic spices: Just salt, pepper, and paprika
Cooking Method
- 1. Get Mushrooms Ready:
- Clean caps with cloth (skip washing). Gently twist stems off. Push sides to create more space inside. Mix with oil, balsamic, salt and pepper.
- 2. Prepare Stuffing:
- Chop veggies into tiny pieces. Blend with shredded cheeses. Sprinkle in herbs and spices. Sample and add more salt if needed.
- 3. Stuff Each Cap:
- Drop mixture into mushrooms. Press down firmly but don't overfill. Keep edges clear. Set them on plate as you finish each one.
- 4. Cook Time:
- Set air fryer to 320°F. Put mushrooms in basket. Leave room between them. Cook about 9-10 minutes till golden. Look at them halfway.

Frequently Asked Questions
- → Why isn’t rinsing mushrooms recommended?
- Mushrooms soak up water easily, which leaves them soggy. Use a damp cloth instead to clean them gently.
- → Can I prep these in advance?
- Yes! Clean and stuff the mushrooms up to a day ahead. Just keep them covered in the fridge until you’re ready to cook.
- → What cheese works best here?
- Mozzarella works great, but try cheddar, Monterey Jack, or a cheese mix for new flavors.
- → How will I know when they’re ready?
- The mushrooms should be soft and dark brown, with the cheese melted and starting to brown slightly.
- → Any tips for making them spicy?
- Absolutely! Add more jalapeños, use spicier chili powder, or mix in some red pepper flakes.
