Mediterranean-Inspired Stuffed Portobello Mushrooms

I’m a sucker for an amazing portobello mushroom. I’m also a sucker for most things Mediterranean. This recipe marries the two with beautiful and delicious harmony! This can be served as a starter, side, or even as the main course, depending on the size of caps you find.

It is a warm and satisfying twist on a classic Caprese salad. Fresh basil doesn’t hold up well to heat, so pesto sauce is used instead. You can used prepared pesto for this recipe, but for best results, try it with this Fresh Basil Pesto recipe.

You can use either fresh or dried mozzarella in this recipe. Fresh is really delicious and it melts beautifully, but it has a higher moisture content. As a result, there may be some excess moisture in the pan after baking. Portobello mushrooms tend to be absorbent, so I lean more toward the dryer cheese.

Preparation Tip: To prepare the portobello caps, gently remove stems by hand. Then, scoop out the gills with a spoon and discard. This will give you more room to add your toppings, plus it will remove any residual grit.
