Grilled Portabella Mushroom Burgers

There’s something so satisfying about biting into a juicy burger, especially on a warm summer evening. As a kid, my family’s backyard barbecues were legendary, but as I grew older, I craved something a bit lighter and more flavorful than the usual beef patties. That’s when I discovered the magic of portabella mushroom burgers. The earthy depth of the mushrooms, infused with a tangy marinade and topped with melty provolone, brought a whole new level of deliciousness to our grill. This recipe brings back those carefree summer nights with every bite.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 10-16 minutes
• Total Time: 25-31 minutes
• Servings: 4
• Dietary Type: Vegetarian

Ingredients

• 4 large portabella mushrooms
• 1/4 cup balsamic vinegar
• 2 tablespoons olive oil
• 1 teaspoon dried basil
• 1 teaspoon dried oregano
• 2-4 cloves garlic, finely minced
• Salt and pepper to taste
• 4 ounces sliced provolone cheese
• 4 whole wheat rolls
• Optional toppings: sliced tomatoes, romaine lettuce leaf, sliced grilled onion, Dijon mustard

Equipment Needed

• Shallow dish
• Whisk
• Grill

Instructions

1. Begin by prepping the mushrooms. Carefully cut off the stems of the portabella mushrooms. Place the mushroom caps, smooth side up, in a shallow dish.

2. Season the mushrooms. Lightly sprinkle the insides of the mushroom caps with salt and pepper.

3. Prepare the marinade. In a small bowl, whisk together the balsamic vinegar, olive oil, dried basil, dried oregano, and finely minced garlic. The aroma of the herbs and garlic mingling with the balsamic vinegar is a sign of the deliciousness to come.

4. Marinate the mushrooms. Pour the marinade evenly over the mushrooms in the dish, ensuring each cap is well coated. Allow the mushrooms to stand at room temperature for 10 to 15 minutes, turning them once or twice during that time to ensure even marination. This allows the mushrooms to absorb the flavors of the marinade, resulting in a more flavorful and tender burger.

5. Preheat the grill. Preheat your grill to medium-high heat. Ensure the grates are clean to prevent sticking.

6. Grill the mushrooms. Place the marinated mushrooms on the preheated grill, reserving the remaining marinade for basting.

7. Cook and baste the mushrooms. Grill the mushrooms for 5 to 8 minutes per side, basting frequently with the reserved marinade. The marinade will help to keep the mushrooms moist and add another layer of flavor as they cook. Watch carefully to prevent burning.

8. Add the cheese. During the last 2 minutes of grilling, top each mushroom cap with a slice of provolone cheese. Allow the cheese to melt and become gooey.

9. Assemble the burgers. Serve the grilled portabella mushroom burgers on the whole wheat rolls. Add your favorite toppings such as sliced tomatoes, romaine lettuce, sliced grilled onion, and a smear of Dijon mustard.

Expert Tips & Tricks

• Maximize flavor: For an even more intense flavor, marinate the mushrooms for a longer period of time, up to 2 hours, in the refrigerator.
• Prevent soggy burgers: Before grilling, gently pat the mushrooms dry with a paper towel to remove excess moisture. This will help them to brown better on the grill.
• Grilled onions made easy: Grill sliced onions alongside the mushrooms for a classic burger topping. Toss them with a little olive oil, salt, and pepper before grilling.
• Add some heat: For a spicier burger, add a pinch of red pepper flakes to the marinade or use pepper jack cheese instead of provolone.
• Versatile marinade: This marinade works well with other vegetables too! Try marinating zucchini, bell peppers, or eggplant and grilling them alongside the mushrooms for a veggie-packed burger.
• Even cooking: When grilling, place a heavy pot lid or grill press over the mushrooms. This helps them to cook more evenly and prevents them from curling up.

Serving & Storage Suggestions

Serve these delicious portabella mushroom burgers immediately after grilling for the best taste and texture. The warm, melted cheese and juicy mushroom are irresistible straight off the grill.

If you have any leftovers, store the grilled mushroom caps in an airtight container in the refrigerator for up to 3 days. Reheat them gently in a skillet or microwave before serving. The whole wheat rolls are best stored separately at room temperature.

These burgers are best eaten fresh, but the grilled mushroom caps can be stored for a day or two. Reheating them in a skillet with a touch of olive oil will help to restore some of their original texture. I don’t recommend freezing.
