Mushrooms and Base
- 4 large portobello mushroom caps
- 2 tablespoons olive oil
Sauce and Seasoning
- 1/2 cup tomato sauce
- 1 teaspoon dried Italian herbs (oregano, basil, thyme)
- 1/2 teaspoon garlic powder or 1 clove fresh garlic, minced
- Salt and pepper, to taste
Toppings
- 1 cup shredded mozzarella cheese
- 12–16 pepperoni slices (optional; can be swapped for veggies or other proteins)
- Prepare the Mushrooms: Gently clean the portobello mushrooms with a damp cloth to remove dirt. Remove the stems carefully and use a spoon to scrape out the gills to create more space for toppings.
- Preheat and Brush: Preheat the oven to 375°F (190°C). Lightly brush both sides of each mushroom cap with olive oil to aid roasting and enhance flavor.
- Add the Sauce and Herbs: Spoon a generous layer of tomato sauce into each mushroom cap. Sprinkle dried Italian herbs and garlic powder over the sauce. Season with salt and pepper to taste.
- Top with Cheese and Pepperoni: Cover the sauced mushrooms with shredded mozzarella cheese, then arrange pepperoni slices or your chosen toppings evenly on top.
- Bake Until Bubbling and Golden: Place the stuffed mushrooms on a baking sheet and bake for 15-20 minutes, until the cheese is melted, bubbly, and golden brown, and the mushrooms are tender but firm.
Notes
- Choose firm, large portobello mushrooms without bruises for best texture and flavor.
- Removing the gills prevents sogginess and gives more space for toppings.
- Brush mushrooms generously with olive oil for even roasting and added richness.
- Preheat the oven properly to ensure perfect cheese bubbling and mushroom cooking.
- Customize cheese blend by mixing mozzarella with parmesan or other favorites for complex flavor.
