I really didn’t know what to make for Meatless Monday last week, but David spotted some beautiful portobello mushrooms at the grocery store and pointed them out to me. I had been wanting to make mushroom cap pizzas for a long time, so when I saw those beauties, I knew exactly what we were going to have: Portobello Mushroom Cap Pizzas.

How To Make Portobello Mushroom Cap Pizzas:

Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper or aluminum foil; set aside.

Make The Pizza Sauce:

In a small saucepan over low heat; mix together tomato sauce, oregano, basil. Heat until warmed through, then turn off the heat.

Prepare The Mushroom Caps:

Meanwhile, wipe down the mushroom caps with a damp paper towel to remove any dirt. 

Gently scrape off the gills inside the mushrooms caps with a spoon.

NOTE: Removing the gills is optional. You can leave them in, they are edible. However, you will see a dark liquid cook out which may spoil the appearance of the pizzas.

I was kind of on the fence as to whether to bake the caps before adding the cheese and toppings because during the cooking process some liquid cooks out of the mushrooms. I ended up skipping the pre-baking the mushroom caps go with a pizza topped Portobello from the start. 

How could the mushroom liquid be a bad thing?

Turns out it was a good thing. A very good thing indeed! David and I loved them mushroom juice and all.

I hope you enjoy these pizzas as much as we did. At 399 calories a serving, there will be no guilt whatsoever!
