Ingredients

What You’ll Need

Gather your ingredients and get ready to create something special. Each one brings a burst of flavor and texture that complements the others beautifully:

• 4 large portobello mushrooms, stems removed

• 2 tablespoons olive oil – for that golden roasted finish

• 3 tablespoons unsalted butter, melted – rich and silky

• 3 cloves garlic, minced – for deep, savory flavor

• Salt and freshly ground black pepper, to taste

• 8 oz fresh mozzarella, sliced – soft and melty

• 2 medium tomatoes, sliced – juicy and sweet

• 1/4 cup fresh basil leaves – bright and fragrant

• Balsamic glaze, for drizzling – sweet and tangy perfection

Pro Tip: Look for large, firm mushrooms with unbroken caps to create a perfect base for stuffing.

Substitutions and Additions

Want to personalize this dish or make it work with what’s in your fridge? Here are a few delicious and practical swaps:

• Cheese Alternatives: Swap mozzarella for tangy goat cheese or keep it dairy-free with a vegan mozzarella-style shreds—still creamy and satisfying.

• Tomato Varieties: Don’t have slicing tomatoes? Use cherry or grape tomatoes instead. They roast beautifully and add a touch of sweetness to each bite.

• Herb Enhancements: Add fresh oregano or a sprinkle of thyme for deeper herbal notes that play well with the garlic and cheese.

• Protein Boost: Turn this side into a full meal by adding cooked quinoa, white beans, or chickpeas under the cheese for extra substance and nutrition.

Step-by-Step Instructions

Preparation

Preheat your oven to 400°F (200°C) to create the perfect environment for roasting your portobello mushrooms. This temperature ensures they cook evenly, tenderizing them while enhancing their natural flavors.

Next, clean the mushrooms by gently wiping them with a damp paper towel. This simple step removes any dirt and leaves your mushrooms looking fresh and ready. If you like, remove the stems and scrape out the gills—this creates a perfect little “bowl” to hold all your delicious ingredients.

For easy cleanup and to prevent sticking, line a baking tray with parchment paper. The mushrooms will bake to a gorgeous golden brown without any fuss!

Mixing

In a small bowl, combine the melted butter, olive oil, and minced garlic. As the warm butter melts, it will infuse the garlic with a deep, savory aroma that’s sure to make your kitchen smell irresistible.

Now, grab a pastry brush and generously coat the mushrooms with the garlic butter mixture—both inside the caps and on the outer surface. The butter will create a glossy sheen, while the garlic will begin to perfume the mushrooms as they bake. Don’t forget to season with salt and freshly ground black pepper to enhance the mushrooms’ natural umami flavor.

Forming and Shaping

Carefully place the prepared mushrooms on the lined baking tray with the gill side facing up. This allows the mushrooms to hold all that creamy mozzarella and juicy tomato goodness in a perfect little pocket.

Start layering the mushrooms with slices of mozzarella and tomato. The mozzarella will melt beautifully and become bubbly and golden, while the tomatoes soften, releasing their natural sweetness. It’s a simple yet stunning combination that looks as good as it tastes.

Baking or Cooking

Place the tray in the oven and bake the mushrooms for about 10 minutes, or until they’re slightly tender. The mushrooms will begin to soften, and the aroma of roasted garlic will fill the air.

Once they’re slightly tender, return the mushrooms to the oven for an additional 10-12 minutes, or until the cheese is melted and bubbly, and the tomatoes have softened into a luscious, juicy layer. For that extra golden touch, switch your oven to broil for the last 2 minutes of baking. This will give the cheese a crisp, golden top, adding texture and a visual wow factor.

Pro Tip: Ensure your mushrooms are dry before brushing with the garlic butter. This prevents excess moisture from releasing while baking, keeping the mushrooms tender, not soggy.

Finishing Touches

Once you’ve pulled the mushrooms from the oven, they’ll be hot and bubbling with that cheesy goodness. Top each mushroom with a handful of fresh basil leaves, which will add a fragrant, herbaceous kick that balances the richness of the cheese. Then, drizzle with a touch of balsamic glaze for a sweet and tangy finish that ties all the flavors together beautifully.

These Caprese Stuffed Garlic Butter Portobellos are now ready to serve—perfect for impressing your guests or enjoying as a comforting, yet light, meal.
