Mushrooms are my favorite side dish. They’re earthy, yummy, and perfect with just about anything.

What you’ll need

• Button mushrooms: These mushrooms are so easy to stuff and eat! Also known as white mushrooms, just remove the stems and stuff the caps.
• Mozzarella cheese: I use melty mozzarella for this meat-free stuffed mushroom recipe. It helps keep all the filling inside the caps!
• Bell peppers: I use red and yellow bell peppers for this recipe. If you can’t find red and yellow, orange or green would also work!
• Italian seasoning: Typically, this universal seasoning blend is a mix of oregano, basil, thyme, and rosemary. It’s great for meat, veggies, sauces, and pasta dishes too!
• Crushed red pepper: I love the subtle spice that crushed red pepper adds to this classic appetizer.
• Black pepper: The sharp taste of cracked black pepper is the perfect addition to most recipes.
• Salt: Like potatoes, mushrooms need salt to bring out their natural umami flavor.
• Oil: A little oil helps these mushrooms cook evenly without sticking to the air fryer basket. It also helps the seasonings stick to the mushroom and not the mixing bowl!

How to make these stuffed mushrooms

1. Gently wash and dry the mushrooms with a kitchen towel. Be sure to scrub off all the dirt by hand. Remove the stems and scoop out any extra in the middle with a small spoon.
2. Season the mushrooms with salt, pepper, and oil in a mixing bowl. Mix well to coat everything evenly inside and out.
3. To make the filling, mix the mozzarella cheese, yellow bell pepper, red bell pepper, crushed red pepper, Italian seasoning, salt, and pepper. Mix everything until well combined.
4. Stuff the mushroom caps with the filling. To get the mushrooms completely filled, use the back of a spoon to press it firmly inside.
5. Preheat the air fryer to 350 degrees F (or 180 degrees C).
6. Place the stuffed mushrooms in a single layer in the air fryer basket or on the air fryer tray. Air fry at 350 degrees F (180 degrees C) for 5 to 6 minutes.

Trouble with soggy mushrooms?

Since this filling is mostly dry with just peppers, mozzarella cheese, and a couple of seasonings, they shouldn’t end up too soggy — especially in the air fryer!

However, mushrooms can release some moisture when you cook them. So, be sure to dry the mushrooms inside and out before stuffing them to help them stay as dry as possible while their cooking.

Storing leftover

If you have leftovers, they’ll last up to 4 days in the fridge. be sure to put them in an airtight container!

Reheat instructions

You can easily reheat them! Pop them back in the air fryer at 350 degrees F (180 degrees C) for about 2 minutes.

You can also use a conventional oven or the microwave in a pinch. However, if you use the microwave, you may get a chewier final product.
