These air fryer pizza stuffed portobello mushrooms are one of my favorite quick meals to make. They take just minutes to prep, and the air fryer does all the heavy lifting.
The idea is simple – take a portobello mushroom cap, fill it with pizza sauce, cheese, and pepperoni, then air fry it until everything is melted and bubbly.

It’s basically pizza without the dough. If you’re cutting back on carbs or just want something lighter, this is a really satisfying option that still hits that pizza craving.
Portobello mushrooms work perfectly for this because they’re big, sturdy, and have that nice cup shape that holds all the toppings in place.
The whole thing comes together in about 15 minutes from start to finish. Great for a quick lunch, a snack, or even a simple dinner on a busy night.

How to Make
Step 1

Step 2
Brush both sides of the mushroom caps with olive oil and place them gill-side up in the air fryer basket.
Step 3
Air fry at 375F for 5 minutes to slightly soften the mushrooms and release excess moisture.

Top with shredded mozzarella cheese, mini pepperoni, and a sprinkle of dried oregano.

Step 6
Return to the air fryer and cook for 4 to 5 more minutes until the cheese is melted and bubbling.

Tips
Clean the Mushrooms the Right Way
Don’t run your portobello caps under water or soak them. Mushrooms act like sponges and will absorb a ton of moisture, which means they’ll turn out soggy instead of holding their shape in the air fryer.
Just grab a damp paper towel or a clean kitchen towel and gently wipe the tops and undersides to get any dirt off. That’s all they need.
If there’s a lot of dark gills underneath and you want a cleaner look, you can use a spoon to gently scrape them out. This also creates a little more room for your toppings.
Pre-Cook the Mushrooms Before Adding Toppings
That first 5 minutes at 375F with nothing on the mushrooms is really important. Portobellos hold a lot of water inside, and if you skip this step and pile everything on from the start, the water will release while it cooks and make your pizza sauce runny and your cheese watery.

After that first cook, you might notice a little pool of liquid sitting inside the caps. Just tip the mushrooms over and let that drain out before you add the sauce. This one step makes a huge difference in how the final result turns out.
Don’t Overload the Sauce
A quarter cup of pizza sauce split between two mushroom caps doesn’t sound like a lot, but it’s the right amount. Portobello caps aren’t that deep, and if you go heavy on the sauce it will overflow and drip down into your air fryer basket.
Spread about 2 tablespoons into each cap, keeping it mostly in the center and leaving a little edge around the sides. Think of it like leaving a crust on a pizza – you want a small border so everything stays contained.

Frequently Asked Questions
Do I need to remove the gills from the portobello mushrooms?
You don’t have to, but it’s a good idea. The dark gills on the underside of portobello caps can hold a lot of moisture, which might make your stuffed mushrooms a bit watery. They can also give the filling a grayish color that doesn’t look as appetizing.
To remove them, just use a spoon and gently scrape them out. It only takes a few seconds per mushroom and gives you a nicer, cleaner cup to hold all that pizza goodness.
