Topping Ideas

MUSHROOMS: Select portobellos that are whole and have intact gills underneath.

SAUCE: No time to make the sauce? Use a jar of pre-made pizza sauce or marinara! Even Alfredo or basil pesto will do!

MEAT: Italian sausage, crab, bay shrimp, ground beef, chorizo, ham, turkey, or chicken are all excellent choices. Or, go vegetarian and use black beans or small cubes of tofu!

CHEESE: Mozzarella is extra melty, but any cheese works. Pre-sliced cheese like Monterey Jack, Swiss, or cheddar fits perfectly over the top of the mushrooms and saves time from shredding by hand.

TOPPINGS: Anything that goes on a pizza can go on stuffed portobello mushroom pizzas! Pineapple, black olives, onions, green chiles, tomatoes, spinach, and even anchovies will work!

How to Make Stuffed Portobello Mushrooms

Portobello pizzas are super easy to prepare:

  1. Prepare mushrooms by removing the stems and gently scraping out the gills with a spoon. 
  2. Brush the tops with olive oil and bake for 10 minutes.
  3. Meanwhile cook sausage, add tomato sauce, paste, and oregano. Bing to a simmer.
  4. Flip portobellos over and fill with meat sauce, top with cheese and optional toppings.
  5. Return to the oven and bake (per the recipe below)

What To Serve With Portobello Mushrooms

A simple salad makes the best side for these mini pizzas. Try this sweet and tangy spinach and strawberry salad, or a zesty tomato salad recipe. Craving something with Mediterranean flavors? Then give this delicious Greek salad a try.

Quick Tips & Tricks

  • Clean mushrooms by brushing off any dirt or debris instead of rinsing. Mushrooms are spongy and will soak up water and take longer to bake, so brushing is preferred.
  • Freeze mushroom stems to use in future stir-fries, soups, or omelets!
  • Select portobellos that are similar in size so they cook at the same rate.
  • Mini pizzas need mini toppings so be sure meats and veggies are scaled down to easily fit onto each cap.
  • For extra bubbly cheese, place mushrooms under the broiler for 2 minutes after baking.
