Ingredients You’ll Need

The magic of this Grilled Portobello Mushrooms Caprese comes down to a handful of simple ingredients, each chosen to enhance the flavors and textures that make the dish shine. From the rich earthiness of portobellos to the creamy mozzarella and the sweet burst of tomatoes, every component plays an essential role.

• 4 large portobello mushrooms: Cleaned with stems and gills removed for a perfect grilling surface and tender bite.
• Balsamic glaze: Adds a sweet and tangy finishing touch that ties all the flavors together.
• 2 tablespoons extra virgin olive oil: Used in the marinade and for greasing the grill, this ensures juicy mushrooms and prevents sticking.
• 1 tablespoon balsamic vinegar: Provides a subtle acidity in the marinade and Caprese salad, balancing richness.
• 1 large garlic clove, grated: Infuses the mushrooms with aromatic depth and savory notes.
• 1 teaspoon fresh rosemary, finely chopped: Offers a woodsy, herbaceous quality that complements the mushrooms perfectly.
• Salt and ground black pepper: Essential seasonings to bring out the flavors.
• 1 cup fresh mozzarella cheese balls or pearls, drained: Creamy and mild, they melt beautifully atop the warm mushrooms.
• 1 cup cherry or grape tomatoes: Bursting with sweetness and acidity for a refreshing contrast.
• 2 tablespoons fresh basil, thinly sliced: Adds vibrant color and a fragrant herbal note; divided to garnish and mix in the salad.

How to Make Grilled Portobello Mushrooms Caprese

Step 1: Marinate the Mushrooms

Begin by whisking together the marinade ingredients: extra virgin olive oil, balsamic vinegar, grated garlic, freshly chopped rosemary, salt, and pepper. Place your cleaned portobello mushrooms into a resealable bag or shallow dish, then pour the marinade over them. Gently toss to coat the mushrooms evenly and let them sit for about 10 minutes, flipping once to make sure every side soaks up that delicious garlicky-herb mixture. This quick marinade infuses the mushrooms with layers of flavor while helping them stay juicy on the grill.

Step 2: Prepare the Grill and Cheese-Tomato Mixture

While the mushrooms are soaking in the marinade, heat your grill or grill pan over medium-high heat and clean the grates thoroughly to avoid sticking. Just before grilling, brush the grates lightly with olive oil. Meanwhile, combine the fresh mozzarella balls, sweet cherry tomatoes, one tablespoon of thinly sliced basil, balsamic vinegar, salt, and pepper in a medium bowl. This Caprese salad is fresh, vibrant, and ready to top your mushrooms.

Step 3: Grill the Portobello Mushrooms

Remove the mushrooms from the marinade, letting any excess drip off. Place them on the hot grill, starting with the stems side down, and cook for about 4 to 5 minutes. Then flip and cook the other side for 5 to 6 minutes until the mushrooms are tender and beautifully marked by the grill. The goal here is a charred exterior with a juicy interior—perfect for holding all the Caprese goodness.

Step 4: Assemble and Melt the Cheese

Once grilled, transfer the mushrooms to a plate or sheet pan for easier filling. Spoon the mozzarella and tomato mixture generously into each mushroom cap. Close the grill lid afterward to allow the residual heat to gently melt the cheese. If you’re using a grill pan indoors, cover it with a large lid or briefly place the pan under a preheated broiler until the cheese melts just perfectly. This step creates that luscious gooey texture everyone loves in a Caprese dish, but with a smoky twist.

Step 5: Finish and Serve

Finally, remove the mushrooms from the grill or broiler and drizzle each one with a glossy balsamic glaze. Sprinkle the remaining tablespoon of fresh basil over the top for a burst of color and herbal brightness. Serve these beauties immediately for the best balance of warm, melted mozzarella with the fresh, crisp Caprese salad flavors.

How to Serve Grilled Portobello Mushrooms Caprese

Garnishes

A sprinkle of flaky sea salt or a handful of microgreens can elevate your Grilled Portobello Mushrooms Caprese with extra texture and freshness. Don’t be shy with the basil garnish—it adds a pop of green and a fragrant note that really brings out the Italian vibe.

Side Dishes

This dish pairs beautifully with a crisp green salad dressed in lemon vinaigrette, crusty garlic bread, or even a light quinoa salad. The goal is to complement the rich mushrooms and bright Caprese flavors without overpowering them. A glass of chilled white wine or sparkling water with a slice of lemon can complete the meal perfectly.

Creative Ways to Present

Looking to impress at your next dinner party? Serve each grilled portobello topped with the Caprese salad on a wooden cutting board for rustic charm, or plate them on individual small dishes with a drizzle of balsamic glaze artistry around. You might even stack two smaller portobellos with layers of mozzarella and tomato for a playful take on a Caprese tower.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers—which might not happen because this dish is so good—store the grilled mushrooms and Caprese salad components separately in airtight containers. Keep them refrigerated and consume within 2 days for the best taste and texture.

Freezing

Freezing isn’t ideal for this dish because the fresh mozzarella and tomatoes lose their texture once thawed, and the mushrooms can become mushy. It’s best enjoyed fresh or within a couple of days stored in the fridge.

Reheating

To reheat your grilled portobello mushrooms with Caprese, gently warm the mushrooms alone in a skillet over medium heat or in a low oven. Add the Caprese salad and fresh basil only just before serving to preserve freshness and flavor. If you want the cheese melted again, pop it under a broiler for a minute or two—keep a close eye to avoid burning.

FAQs

Can I use other types of mushrooms for this recipe?

While portobello mushrooms are ideal due to their size and meaty texture, you can experiment with large cremini or shiitake mushrooms. Just keep in mind smaller mushrooms will need adjusting in grilling time and might not hold as much Caprese topping.

Is this recipe vegan-friendly?

The traditional Grilled Portobello Mushrooms Caprese includes fresh mozzarella, which is not vegan. However, you can easily swap it with plant-based mozzarella alternatives to keep the flavor profile while making it vegan-friendly.

Can I prepare this dish indoors without a grill?

Absolutely! Use a grill pan on the stovetop or broil the mushrooms in the oven. Just make sure to oil your pan well and watch closely to get that nice char and tender texture.

How long can I marinate the mushrooms for the best flavor?

Marinating for 10 minutes as suggested gives plenty of flavor without making the mushrooms soggy. If you want a stronger taste, you can marinate up to 30 minutes but avoid going much longer so the mushrooms keep their texture.

What can I drizzle instead of balsamic glaze?

If you don’t have balsamic glaze on hand, reduced balsamic vinegar works well. Simply simmer balsamic vinegar until it thickens to a syrupy consistency. Alternatively, aged balsamic vinegar adds a lovely depth without being overly sweet.
