What is Caprese?

Caprese is a combination of fresh mozzarella, tomatoes, and basil.

For this caprese-inspired stuffed mushroom, we use these classic flavors and pack them into a large portobello mushroom cap that has been grilled.

It still has the fresh flavors of caprese and the earthy goodness of the mushroom. To add a little zing, balsamic dressing is a tasty addition.

Recipe Tips

Make this recipe anytime of the week or for special occasions and follow a few of these tips for tasty results.

  • Use Large Mushrooms – Portobello mushroom caps come in a variety of sizes. For this recipe, look for large mushroom caps that are not broken around the edge as they will be easier to stuff.
  • Hot, Melty Cheese – For melty cheese, once the mushroom is flipped with the cap side down, fill the mushroom with a few pieces of mozzarella. Allow to heat until the cheese begins to melt. Remove from the grill and add the remaining salad ingredients.
  • Bake Instead of Grill – If you want to skip grilling portobello mushrooms, you can bake them instead. Lightly coat the mushroom caps in oil and place on a baking sheet with plenty of room around each mushroom. Bake for 25 minutes in a 425 degree oven. Remove from the baking sheet and stuff them with caprese salad.


Caprese flavors stuffed inside a meaty mushroom cap have a beautiful flavor profile. Use this as a way to build more stuffed mushroom recipes either cooked on the grill or baked in the oven. 

  • Chicken Alfredo Stuffed Portobello Mushrooms – Grill mushrooms and then fill with chicken, spinach, penne pasta, and smother in garlic cream sauce.
  • Bacon Cheese Burger Stuffed Portobello Mushrooms – Fill the mushroom caps with burger meat and grill until cooked through. Top with slices of bacon and cheddar cheese. Serve as is or on a bun. 
  • Spinach and Feta Stuffed Portobello Mushrooms – Grill mushrooms and stuff with fresh spinach, crumbled feta, crispy bacon, and diced tomatoes. Serve with a bright and zesty dressing
