These Caprese Stuffed Portobello Mushrooms are my family’s favorite meatless dish. They’re hearty enough to satisfy our carnivorous appetites and packed with flavors we all love. Even better, they are super simple to make and are ready in a jiffy.

My oldest daughter was a vegetarian for 7 years. The rest of us didn’t give up meat during that time, but we would incorporate an occasional meatless meal so that she wasn’t always relegated to eating side dishes for dinner.

Oftentimes, we’d opt for pasta dishes but sometimes I’d get more creative and branch out. These Caprese Stuffed Portobello Mushrooms were one of my more successful experiments and continue to be one of my favorite lunch choices.

The best part? They are absolutely delicious and take less than 20 minutes to make!

How to Make Caprese Stuffed Portobello Mushrooms

Stuffed mushrooms are always a favorite at parties. The problem with most stuffed mushroom recipes though is that they have a lot of steps and involve a lot of dirty dishes.

I wanted a simplified recipe that would be just as tasty. What I came up with is this super easy recipe for Caprese Stuffed Portobello Mushrooms.

First, line a baking sheet with parchment paper to make clean-up a breeze. Then, brush all of the stem-free mushrooms with olive oil before placing them on the parchment paper.

Next, you’ll add the mozzarella cheese, followed by tomato slices.

Bake for 8-10 minutes to melt the cheese.

    Thank you so much for this recipe. My Father in Law used to make different stuffed portobellos all the time. When he passed away, his recipes went with him. I made this for my husband last night and he told me he Daddy made something similar.

    Since I don’t eat mushrooms (or tomatoes) I really had no way to gauge what was good or not. I have grown to trust your recipes and knew this would be perfect for my hubby!

    Thanks again for letting me touch my husband with this gesture!
