Portobello Pizzas make a quick and easy appetizer and is definitely something different than the typical finger foods you’d find at an event. Even better, you can make those on a diet as there is no carb-laden pizza crust. Instead, the portobello serves as a base for all the delicious pizza ingredients. Add mozzarella cheese, tomato sauce, pepperoni, and herbs, and you have all the pizza flavor packed into a single bite. The mushrooms are juicy and tender, while the texture is chewy (thanks to the mozzarella cheese!). This serves as a basic recipe, but feel free to customize it as you want.

Portobello Pizza Ingredients

You only need a handful of ingredients to make these Portobello Mushrooms. Look for the largest portobello mushrooms you can find. At the same time, they shouldn’t be too flat, as they need to hold the ingredients. Look for large, deep mushrooms.

Mozzarella cheese will work best for this recipe, as it has enough stretch. If you don’t have mozzarella, you can also use Swiss cheese.

Pepperoni and tomato sauce is an absolute must for maximum pizza flavor. Finally, add some Italian herbs for delicious flavor.


How to make Portobello Pizza

The large portobello mushrooms are first seasoned with oil and then spices are added. The mozzarella cheese is added, together with pepperoni. They’re then baked in the oven until the mushrooms are cooked through, and the cheese has melted.

Tips for the Best Portobello Pizza

– These Portobello Pizzas are keto-friendly and suitable for those following a gluten-free diet (just make sure that your spice is also gluten-free!).

– For extra herby flavor, add a teaspoon of basil pesto to each mushroom cap before adding the cheese.

– To prevent the mushrooms from becoming soggy, you can place them on a grid on top of a baking tray. This will allow the excess moisture to drain off.

– The Portobello Pizzas can be cooked in the Airfryer. Simply place the stuffed mushrooms in the basket and cooked for 8 minutes at 370°F.
