Caprese Stuffed Portobello Mushrooms Recipe at The Little Shop of Olive Oils

If you're looking for an easy recipe that feels a little special without requiring a lot of effort, these Caprese Stuffed Portobello Mushrooms are one of my favorites. They're hearty enough to enjoy as a light meal, elegant enough for entertaining, and packed with fresh Mediterranean flavors.

Large Portobello mushrooms become the perfect edible bowl for juicy cherry tomatoes, creamy fresh mozzarella, fragrant basil, and a generous drizzle of our Oregano White Balsamic Vinegar. Paired with our Garlic Olive Oil, every bite is bright, savory, and wonderfully balanced.

As the mushrooms roast, they become tender and meaty while the tomatoes soften and the mozzarella melts into every nook and cranny. A final drizzle of Oregano White Balsamic after baking adds a fresh burst of herbaceous flavor that truly brings the whole dish together.

I love serving these alongside a crisp green salad or warm, crusty bread for an easy weeknight dinner, but they're equally delicious as an appetizer for family gatherings or summer entertaining.

Simple Ingredients, Incredible Flavor

The beauty of this recipe is that it relies on just a handful of fresh ingredients. High-quality olive oil, flavorful balsamic, ripe tomatoes, fresh basil, and creamy mozzarella do all the work, allowing each ingredient to shine.

Serve these mushrooms fresh from the oven while the cheese is perfectly melted, then finish with another drizzle of Oregano White Balsamic and a sprinkle of fresh basil. Every bite is warm, comforting, and bursting with fresh Mediterranean flavor.

Ingredients

4 large Portobello mushroom caps, stems removed
2 tablespoons Garlic Olive Oil
Salt and freshly cracked black pepper, to taste
1½ cups cherry tomatoes, halved
8 ounces fresh mozzarella pearls (or diced fresh mozzarella)
¼ cup freshly grated Parmesan cheese
¼ cup chopped fresh basil, plus extra for garnish
2 cloves garlic, minced
2 tablespoons Oregano White Balsamic Vinegar
1 tablespoon panko breadcrumbs (optional, for added texture)
1 tablespoon Oregano White Balsamic Vinegar
Fresh basil leaves
Freshly grated Parmesan
Fresh cracked black pepper

Directions

Preheat your oven to 400°F.
Gently wipe the Portobello mushrooms clean and remove the stems. If desired, scrape out the dark gills with a spoon for a cleaner presentation.
Brush both sides of each mushroom with Garlic Olive Oil and season lightly with salt and pepper.
Arrange the mushrooms, gill-side up, on a parchment-lined baking sheet.
In a medium bowl, combine the cherry tomatoes, mozzarella, Parmesan, basil, minced garlic, Oregano White Balsamic, and optional panko breadcrumbs.
Spoon the filling evenly into each mushroom cap.
Bake for 20–25 minutes, or until the mushrooms are tender and the cheese is melted and lightly golden.
Remove from the oven and let rest for 2–3 minutes.
Finish with an additional drizzle of Oregano White Balsamic, extra basil, Parmesan, and freshly cracked black pepper before serving.
