Quick Facts
Yield: Serves 4
Prep Time: 15 minutes
Cook Time: 20 minutes
Total Time: 35 minutes
Ingredients
For the Main Dish:
4 large portobello mushroom caps, stems removed and gills scraped out
1 cup cherry tomatoes, halved
8 ounces fresh mozzarella, cut into small cubes or slices
1/4 cup fresh basil leaves, roughly chopped or torn
2 tablespoons extra virgin olive oil
1 tablespoon balsamic vinegar
2 cloves garlic, minced
Salt and freshly ground black pepper, to taste
Optional: pinch of red pepper flakes
For the Sauce / Garnish (if applicable):
Additional fresh basil leaves for garnish
Drizzle of balsamic glaze or balsamic reduction (optional but highly recommended)
How I Make It
Step 1:
Start by preheating your oven to 400°F. While it warms up, gently clean your portobello mushrooms with a damp paper towel—don’t rinse them under water or they’ll soak up moisture and become soggy. Carefully remove the stems and use a spoon to scrape out the gills; this will create that perfect little cavity for your stuffing.
Step 2:
In a small bowl, toss together the cherry tomatoes, minced garlic, olive oil, balsamic vinegar, salt, and pepper. If you like a bit of a kick, add a pinch of red pepper flakes here. This mixture will give your stuffing a bright, tangy punch and a lovely garlic aroma.
Step 3:
Place the mushrooms on a baking sheet lined with parchment paper or foil (for easier cleanup). Then, layer each mushroom with the tomato mixture, followed by generous pieces of fresh mozzarella. Don’t be shy—this is where the magic happens. The cheese should be visible and ready to melt over everything.
Step 4:
Pop the mushrooms in the oven and bake for about 15–20 minutes, or until the mushrooms are tender and the mozzarella is melted and bubbling with a slight golden touch.
Step 5:
Remove from the oven and immediately sprinkle with chopped fresh basil. If you have balsamic glaze on hand, a drizzle now will add that signature sweet tang and make these babies look like they belong in a fancy Italian trattoria.
Step 6:
Serve warm, savor the melty, juicy layers, and enjoy the satisfaction of creating something beautiful and delicious with minimal effort!
Variations & Tips
Swap cherry tomatoes for sun-dried tomatoes if you want a more concentrated flavor.
Try adding a sprinkle of pine nuts or walnuts for a nice crunch.
Substitute fresh mozzarella with burrata for an extra creamy surprise.
Add a sprinkle of Italian seasoning or dried oregano to the tomato mixture for an extra herbaceous note.
If you like more sauce, drizzle a little pesto over the mushrooms before baking.
For a vegan twist, use dairy-free mozzarella and add extra garlic and herbs.
How I Like to Serve It
This dish shines as a light vegetarian main course alongside a crisp green salad or crusty garlic bread. In warmer weather, it’s perfect for patio dinners with a chilled glass of rosé. Come colder months, pair it with a cozy bowl of minestrone and call it a comforting Italian feast!
Notes
Store leftovers in an airtight container in the fridge for up to 2 days; reheat gently in the oven to keep the mushrooms from getting soggy.
If you don’t have balsamic glaze, reduce balsamic vinegar slowly over low heat until syrupy for a homemade version.
Closing: With its fresh flavors and satisfying textures, this Caprese Stuffed Portobello Mushroom recipe always feels like a little celebration in every bite.
