Caprese Stuffed Portobello Mushrooms: A Summer Vegetarian Delight
Each bite combines garlic-balsamic, juicy tomato, creamy cheese, and crisp panko topping.
Stuffed portobello mushrooms marry the classic Caprese salad flavors—juicy cherry tomatoes, creamy mozzarella, fragrant basil, a tangy balsamic glaze, and a golden parmesan-panko crunch. With a rich, savory marinade and easy roasting steps, this versatile dish shines as both a hearty vegetarian main and an irresistible starter for gatherings.
Why Caprese Stuffed Portobellos?
If you crave fresh, vibrant flavors and crave-worthy texture, Caprese stuffed portobellos perfectly fit the bill. The recipe infuses every bite with summer’s signature combination: tomatoes at their peak, basil’s herbal pop, creamy cheese, and a drizzle of sweet, tangy balsamic glaze. Unlike many stuffed mushrooms that get soggy or heavy, portobellos—after a savory marinade—stay meaty and satisfying, while the broiled panko topping delivers essential crunch.
- Vegetarian main or appetizer: Substantial enough for lunches or dinners, yet stunning as a crowd-pleasing party dish.
- Quick and easy: Minimal prep, a short marinade, and fast oven roasting make these a weeknight winner.
- Customizable: Swap in different cheeses or herbs to match your taste or fridge contents.
Choosing and Preparing Portobello Mushrooms
How to Pick Portobello Mushrooms
- Choose caps that are firm, plump, and round—avoid wrinkles, soft spots, or cracks.
- Look for smooth, unbroken caps at least the size of your palm for best stuffing results.
- A rounder cap holds filling better, promotes even roasting, and presents beautifully at the table.
Cleaning and Prepping
- Remove the stems by gently twisting and pulling them from each cap.
- Wipe the caps gently with a damp paper towel to remove dirt—avoid soaking them, as mushrooms easily absorb moisture.
- Scrape out the dark gills on the underside with a spoon or small paring knife. This step eliminates muddy flavors and makes room for more delicious filling.
Tip: If prepping mushrooms in advance, store them cleaned and wrapped in paper towels in the fridge for up to 24 hours before marinating.
Ingredients
| Ingredient | Amount | Notes |
|---|---|---|
| Large portobello mushroom caps | 6 (about 1 1/4 lb) | Choose even-sized caps |
| Garlic cloves, finely chopped | 2 | For marinade |
| Balsamic glaze | 2 Tbsp (+ more for drizzling) | For marinade and finishing |
| Olive oil | 6 Tbsp | Divided for marinade, filling and topping |
| Kosher salt | 3/4 tsp | Divided |
| Black pepper | 3/4 tsp | Divided |
| Cherry tomatoes | 1 cup (about 6 oz), halved | Fresh, ripe |
| Fresh mozzarella, cubed | 4 oz (about 3/4 cup) | |
| Italian seasoning | 1/4 tsp | |
| Panko breadcrumbs | 1/4 cup | |
| Grated parmesan cheese | 1/4 cup (about 1 oz) | |
| Fresh basil leaves | To serve | For garnish |
Instructions: Step-by-Step
- Clean the mushrooms: Wipe the caps, remove the stems, and scrape off the gills from each portobello. Pat dry.
- Marinate: In a shallow dish, whisk garlic, balsamic glaze, 4 tablespoons olive oil, 1/2 teaspoon salt, and 1/2 teaspoon pepper. Add mushrooms, turning to coat. Marinate at least 15 minutes, or up to 1 hour, turning halfway.
- Preheat oven: Set oven to 425°F and line a baking sheet with parchment paper for easy cleanup.
- Roast mushrooms: Arrange mushrooms stem-side down on baking sheet. Roast 10 minutes. Flip and roast 5–10 minutes more until tender.
- Make filling: In a bowl, combine halved tomatoes, cubed mozzarella, Italian seasoning, 1 tablespoon olive oil, and remaining 1/4 teaspoon each salt and pepper.
- Prepare topping: In a small bowl, toss panko and parmesan with remaining 1 tablespoon olive oil.
- Stuff and top: Turn roasted mushrooms stem-side up. Spoon tomato-mozzarella mixture evenly among caps. Sprinkle with panko-parmesan topping.
- Bake again: Return mushrooms to oven 12–15 minutes, until cheese is melted and breadcrumb topping is crisp and golden.
- Finish and serve: Top with basil leaves and drizzle with balsamic glaze. Serve immediately.
Tips for Perfect Stuffed Portobellos
- Choose quality produce: Since the dish is simple, use the best tomatoes, mozzarella, and basil you can find.
- Don’t skip the marinade: The garlic-balsamic soak deeply flavors the mushrooms, rather than leaving them bland or watery.
- Scrape the gills: This prevents muddiness and sogginess.
- Roast before stuffing: Par-roasting mushrooms ensures they’re tender and removes excess moisture before adding the filling.
- Serve promptly: Stuffed mushrooms are best eaten fresh while warm, with the cheese melting and the panko topping crisp.
