Preheat the Oven: Set your oven to 375°F (190°C) to ensure it’s ready for baking.
Prepare the Mushrooms: Clean the portobello mushrooms by wiping them gently with a damp cloth to remove any dirt. Carefully remove the stems and place the mushrooms on a baking sheet lined with parchment paper, ensuring the gill side is facing up.
Create the Caprese Filling: In a mixing bowl, add the halved cherry tomatoes, mozzarella balls, chopped basil leaves, balsamic vinegar, extra virgin olive oil, minced garlic, salt, and pepper. If you enjoy a bit of heat, add the red pepper flakes. Mix the ingredients gently until well combined, taking care not to break the mozzarella balls.
Stuff the Mushrooms: Use a spoon to generously fill each portobello mushroom cap with the Caprese mixture. Pack them slightly full to ensure they hold all the delicious filling.
Add Extra Flavor: Drizzle a bit of extra virgin olive oil over the stuffed mushrooms. This will enhance the flavors as they bake.
Bake: Place the baking sheet in the preheated oven and bake for about 20 minutes. The mushrooms should become tender, and the cheese will start to bubble and turn golden.
Cool and Serve: Once baked, remove the mushrooms from the oven and let them cool slightly before serving.
