Ingredients You’ll Need

For this Caprese Stuffed Portobello Mushrooms Recipe, I like to focus on quality ingredients that really sing together—fresh tomatoes and basil are key, and I always pick lively, firm mushrooms to hold all that goodness.

• Olive oil: Choose good quality extra virgin for the best flavor and to sauté your tomatoes just right.
• Grape or cherry tomatoes: These little gems blister beautifully and offer a sweet-tart burst in every bite.
• Kosher salt: It seasons evenly without being too salty, perfect for balancing the tomato sweetness.
• Fresh ground pepper: Adds just the right amount of kick. Freshly cracked makes all the difference.
• Garlic cloves (minced): Brings aromatic warmth to the tomato mixture—don’t skip this!
• Fresh basil leaves: Sliced thinly so you get little herbaceous surprises throughout the dish.
• Portobello mushrooms: Their large caps are perfect for stuffing, and they have a meaty texture that holds up well when baked.
• Mini mozzarella balls (ciliegine): Soft and creamy, these little mozzarella gems melt beautifully over the mushrooms.
• Grated Parmesan cheese: Adds a nutty, salty finish to brighten the dish.
• Additional olive oil to drizzle: I use this to add a glossy finish and to keep everything juicy during baking.

Variations

I like to switch up this Caprese Stuffed Portobello Mushrooms Recipe depending on what I’m in the mood for or what’s in the fridge. It’s a flexible dish that invites creativity, so don’t be shy about making it your own!

• Adding balsamic glaze: I drizzle a touch of balsamic reduction over the finished mushrooms for a tangy-sweet contrast that my family absolutely loves.
• Using goat cheese instead of mozzarella: For a tangier, creamier filling, goat cheese upends the classic but is delicious in its own right.
• Spicy kick: Toss in a pinch of red pepper flakes when sautéing the tomatoes if you want to add a little heat.
• Herb swaps: Fresh oregano or thyme can be fantastic alternatives or additions to basil if you want to mix up the flavor profile.

How to Make Caprese Stuffed Portobello Mushrooms Recipe

Step 1: Sauté the Tomatoes Just Right

Start by heating 2 tablespoons of olive oil over medium-high heat in a sauté pan. One trick I learned after some splatter-filled mishaps is to make sure your tomatoes are dry—wet tomatoes mean oil splatters, and nobody wants that! Add your grape or cherry tomatoes, along with ½ teaspoon kosher salt and a generous pinch of freshly ground pepper. Let them cook, stirring occasionally, until they brown in spots and begin to blister—about 5 minutes. Pierce a few of the tomatoes to release their juice, then cover the pan and let them soften for another 10 minutes. This softening step really deepens their flavor and makes the mixture luscious.

Step 2: Flavor the Tomatoes with Garlic and Basil

Once the tomatoes start getting soft, stir in the minced garlic and half of your sliced basil. Lower the heat to low, cover the pan again, and cook for an additional 5 minutes until most tomatoes have burst open and the garlic aromas fill your kitchen. This slow simmering melds the flavors beautifully, creating the perfect base for your stuffed mushrooms.

Step 3: Prepare the Mushrooms and Assemble

While the tomatoes finish cooking, preheat your oven to 350°F (175°C). Spray a baking dish with oil so the mushrooms don’t stick, then place your cleaned Portobello mushroom caps with their gill side up. I always remove the stems because they can be a bit tough and don’t hold the filling well. Spoon the tomato mixture evenly into the mushroom cup cavities, and if there’s extra tomato goodness – I spread it around the mushrooms inside the pan to catch any drips during baking.

Step 4: Add the Cheese and Bake

Top each mushroom with 4 pieces of halved mini mozzarella balls (ciliegine), nestling them gently into the tomato mixture. Then sprinkle each cap with grated Parmesan cheese and drizzle a little more olive oil on top for beautiful gloss and flavor. Bake the mushrooms for about 20 minutes until softened and the cheese is melted and bubbling. If you want that little golden brown crust on the cheese, I pop them under the broiler for 30 seconds at the very end—just watch them closely so they don’t burn.

Step 5: Finish with Fresh Basil and Serve

Once out of the oven, sprinkle the mushrooms with the remaining fresh basil slices for a fresh pop of color and herbal brightness. Serve warm, and prepare for your friends or family to rave about this delicious, elegant dish!

How to Serve Caprese Stuffed Portobello Mushrooms Recipe

Garnishes

For garnish, I usually stick with extra fresh basil leaves for that aromatic lift, and sometimes a drizzle of balsamic glaze if I want a touch of sweetness and tang. A sprinkle of flaky sea salt right before serving also amps up the flavors beautifully.

Side Dishes

I love pairing these stuffed mushrooms with a light arugula salad tossed in lemon vinaigrette or a crisp, chilled cucumber salad to add refreshing crunch. Garlic bread or crusty baguette slices are perfect for soaking up any juices left on the plate.

Creative Ways to Present

For dinner parties, I like to serve these Caprese Stuffed Portobello Mushrooms Recipe on a large platter with basil sprigs and colorful heirloom cherry tomatoes scattered around—it looks stunning and gets you plenty of “oohs” and “aahs.” Another fun idea is to serve them individually on small plates drizzled with balsamic glaze and a sprinkle of chopped toasted pine nuts for crunch.

Make Ahead and Storage

Storing Leftovers

After cooking, I let the mushrooms cool completely, then store them in an airtight container in the fridge for up to 2 days. The flavors actually meld nicely, but the texture of the mushrooms is best enjoyed fresh.

Freezing

I’ve tried freezing these stuffed mushrooms, but the texture suffers a bit once thawed—especially the mozzarella can become watery. If you’re looking to prep ahead, I recommend assembling but not baking, then bake fresh when ready to serve.

Reheating

For reheating leftovers, I pop them in a 350°F oven for about 10 minutes until warmed through and the cheese is melty again. Avoid microwaving if possible to keep the mushrooms from getting soggy.
