These Portobello Mushroom Pizzas have everything you love about pizza-melty mozzarella, zesty sauce, and crispy-edged pepperoni-served in tender, meaty mushroom caps. They're an easy, satisfying way to enjoy pizza night without making dough.
The secret is roasting the mushrooms before adding the toppings. This simple step removes excess moisture, so every bite is cheesy and flavorful instead of watery.
My grandson loves helping us make these little pizzas! He starts by drawing and coloring a picture of exactly how he wants his pizza to look, then helps choose and prepare the toppings. He watches us assemble his creation and loves seeing the cheese melt in the oven. The adults handle the hot oven and pizzas, but he gets to enjoy seeing his masterpiece come to life!

How We Tested Portobello Mushroom Pizzas
- Mushroom Preparation: Removing the gills reduced moisture and bitterness. Roasting gill-side up made draining easier than roasting gill-side down.
- Roasting Time: We compared 8, 10, and 12 minutes. Ten minutes produced tender mushrooms that held their shape without drying around the edges.
- Moisture Control: Draining or blotting after pre-roasting made the biggest difference. Skipping this step resulted in watery pizzas.
- Oil and Seasoning: Two tablespoons of oil coated four caps better than one. We preferred ¼ teaspoon salt and 1 teaspoon Italian seasoning over larger amounts.
- Topping Ratios: Each mushroom worked best with 1 tablespoon plus 1 teaspoon sauce, ¼ cup mozzarella, and 8-12 mini pepperoni. Larger amounts made the pizzas heavier or wetter.
- Oven Temperature: Of 400°F, 425°F, and 450°F, we preferred 425°F. A 9-minute final bake melted the cheese without overly softening the mushrooms.
- Broiling: One minute under the broiler added appealing color; longer broiling risked toughening the edges.
- Leftovers: Air frying produced the best reheated texture, followed by the oven. Assembled pizzas became noticeably watery after freezing and thawing.
Ingredients
You only need a handful of everyday pizza ingredients and four large mushrooms to make this easy dinner.
- Portobello Mushrooms: Choose four firm, similarly sized caps, approximately 4-5 inches wide, to hold the toppings.
- Olive Oil, Salt, and Pepper: Lightly coat and season the mushrooms before roasting.
- Pizza Sauce: Thick sauce provides classic tomato flavor without adding excessive liquid.
- Mozzarella Cheese: Low-moisture shredded mozzarella melts smoothly and keeps the pizzas from becoming watery.
- Mini Pepperoni: Adds savory, slightly spicy pizza flavor in bite-sized pieces.
- Italian Seasoning: Brings together the familiar herbs found in traditional pizza.
- Optional Toppings: Red onion, sliced olives, and fresh basil add extra flavor and color.
The printable recipe card below includes the exact measurements and complete cooking instructions.
Variations
- Vegetarian Mushroom Pizzas: Omit the pepperoni and add finely diced bell peppers, onions, or olives. Use vegetarian cheese if needed.
- Supreme Pizza: Add small amounts of cooked sausage, diced peppers, and red onion alongside the pepperoni.
- Margherita-Style: Skip the pepperoni and finish the baked pizzas with fresh basil and a little grated Parmesan.
- Spicy Pepperoni: Add crushed red pepper flakes or a few sliced jalapeños for extra heat.
How To Make Portobello Mushroom Pizzas
These pizzas come together in four simple steps. Pre-roasting the mushroom caps before adding the toppings is the key to the best texture.
Step 1: Prepare the Mushrooms. Preheat the oven to 425°F. Line a rimmed baking sheet with parchment paper. Wipe the mushrooms clean with a damp paper towel, remove the stems, and gently scrape out the gills with a spoon.
Step 2: Season and Pre-Roast. Brush both sides of the mushrooms with olive oil and season with salt and pepper. Arrange gill-side up on the prepared baking sheet and roast for 10 minutes. Carefully pour off or blot away any liquid released by the mushrooms.
Step 3: Add the Pizza Toppings. Spread approximately 1 tablespoon plus 1 teaspoon pizza sauce inside each mushroom cap. Sprinkle with Italian seasoning, then top each with ¼ cup mozzarella, approximately 8-12 mini pepperoni, and any optional toppings.
Step 4: Bake and Serve. Return the pizzas to the oven and bake for approximately 9 minutes, until the mushrooms are tender and the cheese is melted and bubbly. If desired, broil for 1 minute for additional browning, watching closely. Garnish with fresh basil and serve warm.
Air Fryer Instructions
Preheat the air fryer to 375°F. Arrange the prepared mushroom caps gill-side up in the basket and cook for 6-8 minutes. Drain any released liquid, add the sauce, mozzarella, pepperoni, and seasonings, then air fry for another 5-7 minutes until the cheese melts. Cook in batches if necessary.
Expert Tips
- Choose Firm Mushrooms: Avoid caps that are slimy, bruised, or excessively soft.
- Use Thick Sauce: A concentrated pizza sauce works better than a thin pasta sauce.
- Keep Toppings Small: Finely dice vegetables so they cook quickly and fit comfortably inside the caps.
- Don't Overcrowd the Pan: Leave space around each mushroom for more even roasting.
- Serve Hot: The cheese and mushroom texture are best shortly after baking.

Storage Directions
Refrigerator: Store cooled leftovers in an airtight container for up to 3 days. They're best within the first 24 hours.
Freezer: Avoid freezing fully assembled pizzas because the mushrooms become watery after thawing.
Reheating: Warm in an air fryer or oven until heated through. Microwaving is quicker but produces a softer texture.
Make Ahead: Pre-roast, drain, and cool the caps, then refrigerate separately from the toppings for up to 24 hours. Assemble and finish baking when ready to serve.

What kind of cheese?

You really can use any kind! I usually use a mozzarella cheddar blend of just mozzarella. Whatever you have on hand or prefer will work! These are yummy! I hope you enjoy them! Take care and all the best. Karin
