We make this flatbread pizza by topping it with red peppers, mushrooms, cheese and a white sauce. Remove the red peppers to make it a purely mushroom pizza.

Red Pepper and Maitake Mushroom Flatbread Pizza. Maitake what? It’s just a type of mushroom that is fantastic. Should you not be able to find maitakes, substitute a mushroom you can find at your grocery store, although, I highly recommend maitake mushrooms. They have got a ton of flavor and look like this:

And yes I realize that this is flatbread pizza is vegetarian and that most people come to this site for meat porn.

For those of you that love meat on your pizza, feel free to add some, but I will say that the maitake mushrooms are very meaty on their own and are an excellent substitute. It’s okay to go vegetarian every now and again

Red Pepper and Maitake Mushroom Flatbread Pizza Ingredients:

  • 1 red bell pepper, sliced into rings, seeds and white flesh removed
  • 1 pizza crust (I used a pre-made flat bread pizza crust)
  • 2 tbsp olive oil, divided
  • 2 tbsp alfredo sauce
  • 1/8 cup provel cheese
  • 1/8 cup mozzarella cheese
  • 3 oz maitake mushrooms
  • 1 tbsp grated pecorino romano
  • 1/2 tsp chives, chopped

Prepare the grill for high heat grilling. In this case, I set my gas grill to high and closed the lid.

Char the Peppers

Slice the red pepper into rings and remove the white flesh and place the rings on the hot gas grill, although a charcoal grill will work too:

The goal here is to get a little char on the red pepper and soften them up. After a few minutes and a little char, flip the rings:

Next brush one side of the flatbread pizza crust with oil:

Place the pizza crust oil side down on the grill:

Then brush the other side of the flatbread crust with the rest of the oil:

Once the pizza crust browns a little on the bottom, rotate to brown more of the bottom.

This process should take only a few minutes or the grill is not hot enough.

Remove the peppers when there is a little char on both sides and remove the flatbread pizza crust when it is brown and crispy on the bottom.

The crust should look like this:

Yes, I cross hatched my crust!

Spread the Alfredo sauce:

Time for the cheese. Some of you are wondering what Provel is. It’s sort of a St. Louis thing.

It’s a wonderful buttery white cheese often sold as roped Provel like this:

If you can’t find Provel, use whatever white cheese you prefer. Provel is a pretty oily cheese which is the reason for the buttery flavor so I cut it with some mozzarella to keep the pizza from getting soupy.

Apply the Toppings

Put down the Provel, mozzarella, roasted red peppers, maitake mushrooms and then sprinkle with the pecorino Romano and chopped chives:

Then place the mushroom pizza back on the grill and close the lid:

As the grilled pizza browns on the bottom, rotate to cross hatch the pizza crust and give more time to melt the cheese and warm up the toppings.

Once it is browned well on the bottom the edges of the crust will be browned, the cheese melted, the toppings hot.

At this point it’s ready to come off the grill:

Remove the mushroom pizza from the charcoal or gas grill and place on a cutting board:

Flatbread Pizza Summary:

The flatbread pizza crust was uber crunchy thanks to the double browning, the cheese super gooey, the peppers perfectly roasted, and the maitake mushrooms were hearty making for a wonderful substitute to meat on a pizza. If vegetarian isn’t plant based enough for your dietary needs, use a cheese substitute to make it vegan.

Scott Thomas, the Original Grillin’ Fool, was sent off to college with a suitcase and a grill where he overcooked, undercooked and burned every piece of meat he could find. After thousands of failures, and quite a few successes, nearly two decades later he started a website to show step by step, picture by picture, foolproof instructions on how to make great things out of doors so that others don’t have to repeat the mistakes he’s made on the grill.
