Portabella Burgers With Balsamic and Blue Cheese

I’ll never forget the first time I bit into a portabella burger. It was at a small bistro in the city, and I was initially skeptical. A mushroom burger? But the aroma of balsamic vinegar and the promise of creamy blue cheese piqued my curiosity. One bite, and I was converted. The earthy, meaty texture of the portabella, combined with the tangy balsamic and sharp blue cheese, was an explosion of flavor. It was an experience that proved even the simplest ingredients could come together to create something truly extraordinary, a lesson I’ve carried with me throughout my culinary journey.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 8-10 minutes
• Total Time: 25 minutes
• Servings: 2
• Dietary Type: Vegetarian

Ingredients

• 2 large portabella mushroom caps, stemmed
• 3 tablespoons balsamic vinegar
• 1 tablespoon olive oil
• 1 teaspoon minced fresh garlic
• ½ teaspoon pepper
• ¼ teaspoon salt
• ¼ cup crumbled blue cheese or ¼ cup gorgonzola
• 2 tablespoons light mayonnaise
• 1 teaspoon balsamic vinegar
• 2 whole wheat hamburger buns, split
• Romaine lettuce leaf
• 2 slices tomatoes

Equipment Needed

• Shallow dish or large zip-top plastic freezer bag
• Grill or grill pan

Instructions

1. Begin by preparing the portabella mushrooms. Gently scrape the gills from the inside of the mushroom caps. This helps prevent a muddy texture and concentrates the earthy flavor.

2. In a shallow dish or a large zip-top plastic freezer bag, combine 3 tablespoons of balsamic vinegar, 1 tablespoon of olive oil, 1 teaspoon of minced fresh garlic, ½ teaspoon of pepper, and ¼ teaspoon of salt. This mixture will be the flavorful marinade for the mushrooms.

3. Add the mushrooms to the marinade, ensuring they are well coated. Cover the dish or seal the bag, and chill in the refrigerator for 1 hour, turning the mushrooms occasionally to ensure even marination. This step is crucial for infusing the mushrooms with the balsamic flavor.

4. After marinating, remove the mushrooms from the marinade and discard the marinade. It has already imparted its flavor, and we don’t want excess liquid on the grill.

5. Preheat your grill to medium-high heat (350° to 400°F). If you don’t have a grill, a grill pan on the stovetop works just as well.

6. Grill the mushrooms, covered with the grill lid (if using an outdoor grill), for 3 to 4 minutes on each side, or until they are tender. The exact cooking time may vary depending on the size and thickness of the mushrooms. Look for them to soften and release their moisture.

7. Remove the mushrooms from the grill. Immediately sprinkle the undersides (the side that was facing up on the grill) evenly with ¼ cup of crumbled blue cheese or gorgonzola. The heat from the mushrooms will gently melt the cheese, creating a creamy and flavorful layer.

8. While the cheese is melting, prepare the bun spread. In a small bowl, stir together 2 tablespoons of light mayonnaise and 1 teaspoon of balsamic vinegar. This adds a touch of tanginess to complement the other flavors.

9. Spread the mayonnaise mixture evenly on the cut sides of the 2 whole wheat hamburger buns.

10. To assemble the burgers, place a romaine lettuce leaf on the bottom half of each bun. Top with the grilled mushrooms, cheese-side up. Add 2 slices of tomatoes to each burger.

11. Cover with the tops of the buns and serve immediately. Enjoy the delicious combination of flavors and textures!

Expert Tips & Tricks

• For a deeper, more intense flavor, consider using a high-quality aged balsamic vinegar.
• If you don’t have fresh garlic, a pinch of garlic powder can be used as a substitute, but fresh is always preferred.
• Don’t overcrowd the grill. Grill the mushrooms in batches if necessary to ensure even cooking.
• To prevent the buns from getting soggy, lightly toast them on the grill or in a toaster oven before adding the toppings.
• If you prefer a vegan version, use vegan mayonnaise and a plant-based blue cheese alternative.

Serving & Storage Suggestions

Serve these delicious portabella burgers immediately while the mushrooms are warm and the cheese is melted. They pair well with a side of roasted sweet potatoes, a fresh salad, or crispy fries.

If you have leftovers, store the components separately. Place the grilled mushrooms in an airtight container in the refrigerator for up to 2 days. Store the buns at room temperature. Reheat the mushrooms in a skillet or microwave before assembling the burgers. Reassembled burgers are best eaten fresh.
