How to make portobello mushroom pizzas
I’m hooked on stuffed portobello mushroom recipes because you can turn your favorite comfort food into a guilt-free meal. I’ve previously made Enchilada Stuffed Portobellos and Lasagna Stuffed Portobellos, and so clearly it was time for portobello mushroom pizzas!
- Wash your mushrooms well.
- Pull out the stems and reserve. Scoop out the gills with a spoon and discard.
- Brush mushrooms with olive oil and salt & pepper.
- Fill with your favorite pizza toppings! I used chopped mushroom stems, tomatoes, Grimm’s Lean Pepperoni Sticks and onions.
- Cheese it up: I used shredded mozza and a generous sprinkling of parmesan.
- Sprinkle with dried basil.
- More pepperoni!
- Bake ’em.
Can these portobello mushroom pizzas be frozen? Yes! You need to bake them first, allow to cool, then wrap up in parchment or foil. Freeze for 1-2 months. You can either thaw completely or bake from frozen (see full directions in the Lasagna Portobello Mushroom recipe)
Do these portobello mushroom pizzas really last as a meal prep lunch? YES. I was dubious myself, but the mushrooms did not get soggy and were really delicious after heating through in the microwave. I recommend packing with a few extra pepperoni sticks and some fruit (see below).
Can I grill these portobello mushroom pizzas? I haven’t tested this, but I bet that would work great! Refer to the directions in my Enchilada Stuffed Grilled Portobellos.
What other toppings can I use for these portobello mushroom pizzas? You can go wild! I bet bell peppers, olives, pineapple and hot peppers would all be great. I bet using pesto or salsa in place of pizza sauce would be great, too!
What to serve with this pepperoni pizza baked portobello mushroom?
- a simple Kale Salad or a Slaw
