Ingredients

• 4 large portobello mushrooms
• 2 tablespoons olive oil (divided)
• ½ teaspoon salt (divided)
• ½ teaspoon black pepper (divided)
• 1 cup cherry or grape tomatoes, halved
• 1 cup fresh mozzarella balls (bocconcini) or diced mozzarella
• ¼ cup fresh basil leaves, chopped or torn
• 1 teaspoon Italian seasoning
• 2 tablespoons grated Parmesan cheese (optional)
• 2 tablespoons balsamic glaze (store-bought or homemade)

Optional garnishes: Additional fresh basil, red pepper flakes

Step-by-Step Instructions

1. Preheat the oven

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it with olive oil.

2. Prepare the mushrooms

Clean the portobello mushrooms by wiping them gently with a damp paper towel to remove any dirt. Remove the stems and use a spoon to scrape out the gills if desired (this step is optional but helps reduce moisture and create more space for the filling).

3. Season the mushrooms

Place the mushrooms on the prepared baking sheet, cap side down. Drizzle 1 tablespoon of olive oil over the mushrooms and season with ¼ teaspoon of salt and ¼ teaspoon of black pepper. Bake for 8-10 minutes to soften the mushrooms slightly and release excess moisture. Remove from the oven and pat the inside of each mushroom dry with a paper towel if needed.

4. Prepare the filling

In a medium mixing bowl, combine the halved cherry tomatoes, mozzarella balls, chopped basil, remaining 1 tablespoon of olive oil, Italian seasoning, and the remaining ¼ teaspoon of salt and black pepper. Toss gently to coat the ingredients evenly.

5. Stuff the mushrooms

Divide the tomato and mozzarella mixture evenly among the mushroom caps, filling each one generously. Sprinkle grated Parmesan cheese on top if desired for extra flavor and a slightly crispy topping.

6. Bake the mushrooms

Return the stuffed mushrooms to the oven and bake for an additional 10-12 minutes, or until the mozzarella is melted and bubbly.

7. Drizzle with balsamic glaze

Remove the mushrooms from the oven and drizzle with balsamic glaze. Garnish with additional fresh basil leaves and red pepper flakes if desired.

8. Serve immediately

Serve the Caprese stuffed portobello mushrooms hot as an appetizer, side dish, or light main course. Pair with a crisp salad, crusty bread, or a simple pasta dish for a complete meal.

Ingredient Background

• Portobello mushrooms: These large, meaty mushrooms are perfect for stuffing and serve as a hearty base for the dish. Their earthy flavor complements the fresh Caprese filling.
• Mozzarella: Fresh mozzarella adds creaminess and mild flavor. Bocconcini (small mozzarella balls) or diced mozzarella are ideal for even distribution.
• Tomatoes: Cherry or grape tomatoes are sweet and juicy, making them the perfect complement to the creamy mozzarella and earthy mushrooms.
• Basil: Fresh basil is essential for the classic Caprese flavor. Its aromatic and slightly peppery taste elevates the dish.
• Balsamic glaze: A drizzle of tangy, slightly sweet balsamic glaze ties the flavors together and adds a gourmet touch.

Technique Tips

• Avoid soggy mushrooms: Pre-bake the mushrooms to release excess moisture, and pat them dry before adding the filling.
• Use fresh ingredients: Fresh mozzarella, ripe tomatoes, and fragrant basil are key to achieving the best flavor.
• Don’t overbake: Keep an eye on the mushrooms during the second bake to ensure the cheese melts without overcooking the mushrooms.
• Optional gill removal: Removing the gills is optional, but it can help reduce moisture and make the mushrooms less earthy-tasting.

Alternative Presentation Ideas

• Individual servings: Serve one stuffed mushroom per person as a starter or light lunch, garnished with a sprig of basil.
• Party platter: Slice the stuffed mushrooms into quarters and serve as bite-sized appetizers on a platter.
• Over greens: Place the stuffed mushrooms on a bed of arugula or spinach for a fresh, colorful presentation.

Additional Tips for Success

• Room temperature cheese: Let the mozzarella come to room temperature before using to ensure even melting.
• Layer for extra flavor: Add a layer of pesto or a thin slice of prosciutto inside the mushroom before stuffing for a flavor boost.
• Customize the filling: Mix in diced sun-dried tomatoes, roasted red peppers, or olives for additional depth and variety.

Recipe Variations

• Spinach Caprese: Add sautéed spinach to the filling for an extra dose of greens.
• Caprese Chicken Mushrooms: Top the mushrooms with shredded rotisserie chicken before adding the filling for a protein-packed version.
• Vegan Caprese Mushrooms: Use vegan mozzarella and skip the Parmesan to create a dairy-free version.
• Spicy Caprese: Add a pinch of crushed red pepper flakes to the filling for a hint of heat.

Freezing and Storage

• Storing leftovers: Store any leftover stuffed mushrooms in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F for 8-10 minutes.
• Freezing: While the mushrooms can be frozen after baking, the texture of the tomatoes and cheese may change. To freeze, assemble the stuffed mushrooms but do not bake. Freeze them on a baking sheet until solid, then transfer to a freezer-safe container. Bake from frozen at 400°F, adding 5-7 minutes to the cooking time.

Healthier Twist Ideas

• Lower fat cheese: Use part-skim mozzarella to reduce the fat content without sacrificing flavor.
• Add more veggies: Incorporate diced zucchini, bell peppers, or spinach into the filling for extra nutrients.
• Whole30 or keto-friendly: Skip the balsamic glaze or use a sugar-free version to keep the dish compliant with these diets.

Serving Suggestions for Events

• Holiday gatherings: Serve the stuffed mushrooms as a festive appetizer alongside other small bites like bruschetta and stuffed peppers.
• Dinner parties: Pair with a crisp white wine, such as Sauvignon Blanc or Pinot Grigio, for an elegant main course.
• Casual lunches: Serve with a simple side salad or roasted vegetables for a light yet satisfying meal.

Special Equipment

• Baking sheet: A large, rimmed baking sheet ensures the mushrooms bake evenly without spilling the filling.
• Sharp knife: Essential for slicing tomatoes and chopping basil cleanly.
• Parchment paper: Makes cleanup easy and prevents the mushrooms from sticking to the baking sheet.

Frequently Asked Questions
