Pizza Mushrooms

Pizza Mushroom - Buttered Side Up

Not gonna lie: I love me a slice of Pizza Hut super supreme stuffed crust. What I DON’T love about it is the ingredients they use to make it. It contains soy, corn syrup, nitrites, preservatives, flavorings, and I’m sure MSG is hidden in there somewhere. YIKES!

What’s a healthy, pizza-loving girl to do?! Make your own pizza, of course!

Pizza Mushrooms to the Rescue!

Pizza Mushroom - Buttered Side Up
Lately, as I’ve mentioned before, I’ve been trying to cut back on grains in my diet. But I was having a major pizza craving. I’ve tried coconut flour crusts as a grain-free option, which are OKAY, but I wanted to simplify the process a bit.

Mushrooms are a great crust substitute since they are already a yummy pizza topping. Plus, they make these pizzas completely flour-free!

Pizza Mushroom - Buttered Side Up
You can make these pizza mushrooms how I have this recipe written (this is a very classic pizza flavor), or you can substitute with your favorite toppings.

BTW – I used Applegate pepperoni and cut out the cute little circles with scissors. You could also just chop up pepperoni with a knife.

Also, the filling tends to spill out of the mushrooms if the sides of the mushrooms are broken at all. They still taste fine, it’s just less pretty. Try to select mushrooms that have deep “cups” that are not broken.

  • 4 large Portobello mushrooms cleaned, stems removed, and gills scraped out,
  • 1 tablespoon extra virgin olive oil
  • 1 small clove garlic minced,
  • 1/3 cup pizza sauce
  • 1 1/2 cups shredded cheddar cheese
  • 1/4 cup chopped pepperoni more to taste
  • 1/4 cup sliced black olives
  • 2 tablespoons finely chopped red bell pepper
  • 3 tablespoons freshly shredded Parmesan cheese
  • fresh basil leaves as garnish, optional


  1. Preheat oven to 400 degrees F (205 C).
  2. Place the mushrooms, gill side up, on a rimmed baking sheet.  Mix together the olive oil and minced garlic. Spread the olive oil evenly in the "cup" of the mushrooms.
  3. Layer the rest of the ingredients evenly in the mushroom cups: pizza sauce, cheddar cheese, pepperoni, olives, bell pepper, Parmesan cheese, and basil leaves.
  4. Bake in preheated oven for 15-25 minutes, until cheese is nice and bubbly. Remove from oven, allow to cool a bit, and serve with a steak knife.

For me, it's not's so much the gluten, it's the empty calories in white flour. I think it's fine occasionally, but when I'm really trying to step up my nutrition game, I tend to reduce my consumption of it. :)
