These stuffed mushrooms made in the air fryer are a knockout party starter or tasty treat. Crimini mushrooms loaded with a flavorful blend of cheeses, bright peppers, and fresh herbs turn beautifully crisp and juicy when air fried.
Key Ingredients
- Crimini mushrooms: Go for ones roughly 2 inches across
- Mozzarella and Parmesan: Creates a rich, tangy blend
- Bell peppers and onions: Offer texture and natural sweetness
- Leafy herbs: Try cilantro or parsley
- Basic spices: Just salt, pepper, and paprika
Simple Cooking Guide
- 1. Getting Mushrooms Ready:
- Brush mushrooms clean (skipping water). Gently twist stems out. Push edges down to create more room. Mix with oil, balsamic, salt and pepper.
- 2. Whipping Up Filling:
- Chop veggies tiny. Combine with shredded cheeses. Toss in herbs and spices. Sample and add salt if needed.
- 3. Stuffing Process:
- Add filling to each mushroom cap. Press down firmly without overfilling. Keep edges clear. Set them aside as you work.
- 4. Cooking Time:
- Set air fryer to 320°F. Arrange mushrooms in basket. Give them breathing room. Cook for 9-10 minutes until crispy. Take a peek halfway.

Fixing Common Problems
- Mushrooms too wet? Pat them completely dry after cleaning
- Stuffing spilling out? Press it in more tightly
- Not getting golden? Cook a minute or two longer
- Too much liquid? Stay away from juicy veggies like tomatoes
Keeping and Warming
- Store in refrigerator up to 4 days
- Heat again in air fryer for 2-3 minutes
- A quick blast in microwave works too - around 45 seconds
- Skip freezing - they won't taste right after
Prep Beforehand
- Wash and get mushrooms ready early
- Mix filling a day before
- Fill mushrooms right before cooking
- Tastes best fresh from the air fryer
These mushrooms never last long at gatherings. I like cooking a large batch because they're gobbled up fast and everyone wants to know how I made them. They're simple enough for everyday snacks but fancy enough for guests.
Fun Twists to Experiment With
- Italian Twist: Use Italian herbs, swap in basil for cilantro, mix in sun-dried tomatoes, sprinkle extra Parmesan on top
- Mediterranean Style: Add crumbled feta, toss in chopped Kalamata olives, use oregano with dill, finish with fresh lemon
- Spicy Version: Mix in diced jalapeños, dust with red pepper flakes, add a touch of cayenne, use pepper jack cheese
- Upscale Option: Add crab meat, include diced shrimp, pick fresh herbs, finish with truffle oil

These tasty bites can work with so many flavors - after you try the basic version, you can play around with different cheeses and herbs. They're great for planning meals ahead since they warm up so well.
Frequently Asked Questions
- → Why avoid washing mushrooms in water?
- Mushrooms soak up water like sponges, which can make them squishy. Use a damp cloth to gently clean them instead.
- → How far ahead can I prep them?
- You can clean and fill the mushrooms a day before. Keep them in the fridge and cook them in the air fryer when you're ready to serve.
- → What's a good cheese option?
- Mozzarella's great, but you can also use cheddar, jack, or a meltable cheese mix for variety.
- → How do I know they're ready?
- They’re done when the mushrooms are soft and dark, and the cheese is gooey with a little golden crust.
- → How can I turn up the heat?
- Add extra jalapeños, spicier chili powder, or toss in some red pepper flakes to the mix.
