Pesto Mozzarella Portobello Mushrooms

5 from 1 vote
These mushrooms are absolutely delicious... and so simple. All you do is load up the portobello mushrooms with any pesto, tomatoes, mozzarella, and some simple seasonings and bake them until they're soft and the cheese is all melty. It is so easy, and it's one of my favorite ways to prepare mushrooms.
The most important thing here are the ingredients: you want to get the best quality mushrooms. You're looking for mushrooms that aren't discolored or overly dirty.
As for the other ingredients, feel free to use whatever you have. Any tomatoes you have will work, as well as really any cheese. If you don't have shredded mozzarella, feel free to use gruyere or cheddar.
For the pesto, you can either use a store bought/homemade basil pesto, or you can try out my homemade spinach pesto, which is absolutely delicious. You could also try making it with kale, I've been told that's delicious as well.
