Ingredients

Here’s everything you need to make these flavorful Caprese Stuffed Portobello Mushrooms, along with why each ingredient matters and a few helpful tips.

Portobello mushrooms (4 large caps) – Choose large, firm mushrooms with intact caps; they roast beautifully and work like natural bowls for the filling.
Cherry tomatoes (1 cup, halved) – Fresh cherry tomatoes add natural sweetness and hold their shape better than larger tomatoes when baked.
Fresh mozzarella cheese (4 oz, diced or torn) – Fresh mozzarella melts softly and creates the classic creamy Caprese texture; avoid pre-shredded cheese for best results.
Fresh basil leaves (¼ cup, chopped) – Basil adds a bright, aromatic flavor that balances the richness of the cheese and mushrooms.
Garlic (1 clove, minced) – A small amount of fresh garlic enhances savory depth without overpowering the delicate Caprese flavors.
Extra-virgin olive oil (1½ tablespoons) – High-quality olive oil adds richness and helps the mushrooms roast evenly.
Balsamic glaze or reduction (1–2 tablespoons, optional) – Adds a sweet, tangy finish that pairs perfectly with tomatoes and mozzarella.
Salt (¼ teaspoon, or to taste) – Enhances natural flavors and helps draw moisture out of the mushrooms while baking.
Black pepper (¼ teaspoon, freshly ground) – Freshly ground pepper adds subtle warmth and balance to the dish.

How to Make Caprese Stuffed Portobello Mushrooms?

Preparing the Mushrooms

Start by preheating your oven to 400°F (200°C). I gently wipe the mushrooms with a damp paper towel instead of washing them to prevent sogginess. Then I remove the stems and scrape out the gills using a spoon to create space for the filling.

Seasoning and Pre-Baking

Place the mushroom caps gill-side up on a lined baking sheet. I brush them lightly with olive oil and sprinkle with salt and pepper. Baking them for about 5 minutes helps release excess moisture and keeps the final dish from becoming watery.

Making the Caprese Filling

While the mushrooms pre-bake, I mix the halved cherry tomatoes, minced garlic, and a drizzle of olive oil in a bowl. This simple mixture forms the fresh, juicy base of the stuffing and keeps the flavors light and vibrant.

Stuffing the Mushrooms

After removing the mushrooms from the oven, I spoon the tomato mixture evenly into each cap. Then I top them with pieces of fresh mozzarella, making sure each mushroom gets a good balance of tomato and cheese.

Baking Until Melty

The stuffed mushrooms go back into the oven for about 15 minutes. I watch for the cheese to soften and melt while the mushrooms become tender but still hold their shape.

Finishing Touches

Once out of the oven, I scatter chopped fresh basil over the mushrooms. If I’m feeling fancy, I drizzle a little balsamic glaze on top just before serving for extra flavor and shine.

Additional Tips for Making This Recipe Better

After making this recipe several times, I’ve picked up a few tricks that really elevate the results.

I always pre-bake the mushrooms briefly to avoid excess liquid pooling at the bottom.
Using room-temperature mozzarella helps it melt more evenly for me.
I’ve learned not to overstuff the mushrooms, which keeps them from collapsing.
Letting them rest for a couple of minutes after baking helps the flavors settle nicely.

How to Serve Caprese Stuffed Portobello Mushrooms?

I love serving these mushrooms straight from the oven while the cheese is still warm and stretchy. They look beautiful on a platter garnished with extra basil leaves and a drizzle of balsamic glaze. For a complete meal, I pair them with a simple green salad or a slice of crusty bread. They also work wonderfully as a side dish for grilled chicken or fish when I’m serving a mixed crowd.

Make Ahead and Storage

Make Ahead

You can prepare the mushroom caps and tomato filling up to one day in advance. I store them separately in airtight containers in the refrigerator and assemble just before baking.

Storage

Leftover stuffed mushrooms keep well in the fridge for up to 3 days. I place them in a sealed container to maintain freshness and prevent them from drying out.

Reheating

To reheat, I prefer using the oven at 350°F for about 8–10 minutes. This helps the mushrooms warm through without becoming rubbery, unlike the microwave.
