Step 1

Preheat your oven to 450 F and lightly coat a rimmed baking sheet with cooking spray.

Step 2

Clean the mushrooms by wiping them off with a damp paper towel, don't run them under water as they easily absorb liquid. Remove the stems.

Step 3

Place the mushrooms on a baking sheet, grill side up.

Step 4

In a small bowl, mix the olive oil, Italian seasoning, and minced garlic.

Step 5

Brush the olive oil mix on the inside of each portobello mushroom. Add the pizza sauce on the inside of each mushroom cap. Sprinkle on the mozzarella cheese, then top them with sliced cherry tomatoes, and sliced black olives.

Step 6

Bake the mushroom pizzas for 10-12+ minutes in the oven until the mushrooms soften and the cheese melts. Sprinkle with shredded fresh basil and red pepper flakes. Serve immediately and enjoy!
