These portobello mushroom pizzas are packed full of flavor and are a great option if you are on a low carb diet. They are so simple to make and the kids and grown ups absolutely loved them! Perfect to serve as a side, or with a large salad for a delicious dinner.

Ingredients to make the recipe

  • Mushrooms: Use portobello mushroom caps for this recipe. Mushrooms are low in carbs and calories as well as being rich in fiber, proteins and antioxidants. Make sure to look for wide deep ones, and remove the stems.
  • Oil: I use olive oil, but canola or vegetable will both work well.
  • Italian seasoning: A mix of oregano, basil, thyme and rosemary.
  • Pizza sauce: You can make your own marinara sauce or use your favorite store bought jar.
  • Cheese: I use mozzarella which gets nice and stringy when it melts. You can use any type of cheese and it’s also great to garnish the mushroom cap pizzas with a little parmesan for an extra kick of flavor.
  • Toppings: I like to keep it simple since the mushrooms are small. I used sliced cherry tomatoes here, but you can use any fresh veggie toppings or meat toppings.

How to make portobello mushroom pizzas

  1. Place the portobello mushrooms on a baking sheet stem side up.
  2. Divide the ingredients between both portobello mushrooms in order or appearance, first starting with the olive oil, garlic and garlic seasoning mixture.
  3. Add the pizza sauce on top.
  4. Follow it by cheese and couple small, thinly sliced toppings of your choice.

  • Transfer the stuffed portobello mushroom pizzas to a rimmed baking sheet and bake until the cheese is melty, being careful not to over-bake so they don’t get soggy and release too much moisture.

Tips for making the pizzas

  1. Look for wide portobello mushrooms that have a crevice. Some might be really flat on the top, but ones with curves and crevice will hold the seasoning, sauce and cheese better.
  2. Heat the pan inside the oven while you warm it. This is why I sometimes build the mushroom pizzas on a plate first instead of directly on the baking dish. This helps to make sure the mushrooms don’t get soggy when you’re cooking them in the oven.
  3. Don’t let the pizza stuffed portobello sit out for too long before serving. You can prep them ahead of time though and keep them covered in the fridge until you are ready to cook them in the oven.
  4. Don’t clean the mushrooms under running water. Mushrooms are very absorbent, so it’s best to clean them with a damp cloth to remove any dirt. If they absorb a lot of water during cleaning, they can end up quite soggy once they are baked.

What toppings work best?

I stayed classic and vegetarian with the toppings for these; mozzarella, cherry tomatoes and pizza sauce, but you can customize these portobello pizzas however you’d like with whatever ingredients you have on hand. Add slices of turkey pepperoni, shredded chicken, peppers or any of your favorite toppings.

  1. Made this for lunch today and it was perfect and delicious! Followed the recipe exactly (even removed the gills) and it was super-easy. I made mine with tomato sauce, parmesan cheese, red peppers, black olives and cheddar cheese and broiled it for 30 seconds after baking for 10 minutes. Will definitely make again! Thank you 🙂

    1. Did you use wide portobello mushrooms that have a crevice? Some might be really flat on the top, but ones with curves and crevice will hold the seasoning, sauce and cheese better. I also advise not stuffing the mushrooms to the edge because that can naturally happen.

  2. These sound great!
    All your pictures show the mushrooms with the gills, but instructions say to remove them. What’s the issue with retaining the gills, or is that not advisable?

  3. I made jumbo portabello mushrooms. I made my own pizza sauce. There’s lots of recipes online for this. The toppings I used were marinated artichoke hearts and kalamata olives and I put pepperoni on my husband’s and veggies.
    I ran into a couple little problems. The stems were not enough to make a filling. I added some chopped yellow bell peppers and added panko bread filling. Then fried it up with Italian seasoning.

    Being the portabellos were so large, they did not cook enough in my oven. So after baking the mushrooms about 12 minutes on 350 degrees, I removed the mushrooms and fried them up in some olive oil seasoned with Italian seasoning, garlic and a little salt and pepper. They were delicious.

    1. Mmmmm… so good! The only change I made was to add a few more veggies! My husband and I make these for Pizza Friday’s! Thanks for this creative idea!

  4. Followed your instructions to put pan in oven while it’s preheating & then pull pan out, & add mushrooms. Brushed olive oil on mushrooms & seasoned with Italian seasoning and garlic powder. Used crushed tomatoes as the sauce, topped with leftover grilled vegetables & topped with Italian blend shredded cheese. Baked for 10 minutes. They were wonderful & will definitely be made again. Thank you for the simple recipe.
