Grilled Portabella Mushroom Burgers – a La Dave

The sizzle of summer evenings always brings me back to family barbecues. My dad, a man of simple tastes but unwavering grilling dedication, would always champion the humble portabella mushroom. He’d treat it with the same reverence he gave his steaks, marinating them, grilling them just right, and serving them with a flourish. While the rest of us devoured traditional burgers, he savored his “steak of the earth,” a satisfying and flavorful vegetarian delight. This recipe, inspired by countless evenings spent around the grill with him, aims to recreate that simple joy.

Recipe Overview:

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

Ingredients:

• 4 large portabella mushrooms
• 1/4 teaspoon salt
• 1/4 teaspoon pepper
• 1/4 teaspoon garlic powder
• 2 tablespoons balsamic vinegar
• 4 tablespoons extra virgin olive oil, divided
• 4 hamburger buns

Equipment Needed:

• Medium-size skillet
• Small bowl
• Basting brush

Instructions:

1. Begin by preparing the portabella mushrooms. Gently clean them by rubbing lightly with a damp towel. If desired, carefully remove the stems.

2. In a small bowl, create the flavorful marinade. Combine the salt, pepper, garlic powder, balsamic vinegar, and 3 tablespoons of extra virgin olive oil. Whisk the ingredients briskly with a basting brush until well combined. This creates a light emulsion, ensuring the flavors meld beautifully.

3. Heat a medium-size skillet over medium heat. If desired, coat the skillet with the remaining tablespoon of extra virgin olive oil. This helps prevent sticking and adds a touch of richness to the mushrooms.

4. Brush both sides of each portabella mushroom generously with the oil/vinegar mixture. Ensure the mushrooms are thoroughly coated to maximize flavor absorption during grilling.

5. Place the portabella mushrooms, stem side down, in the heated skillet. Grill for 5 minutes. The direct contact with the hot skillet will create a beautiful sear and start the cooking process.

6. Brush the top side of the mushrooms with some more of the oil/vinegar mixture.

7. Carefully turn the mushrooms over and grill for another 5 minutes. Brush the stem side once with the remaining oil/vinegar mixture. During this second grilling phase, the mushrooms will become tender and develop a deep, savory flavor.

8. Remove the grilled portabella mushrooms from the skillet and place them on the hamburger buns.

9. Garnish with your favorite condiments, such as lettuce, tomato, onion, cheese, ketchup, mustard, or mayonnaise. Get creative and customize your burger to your liking.

Expert Tips & Tricks:

• Enhance the Marinade: For an even more complex flavor, try adding a teaspoon of Dijon mustard or a pinch of red pepper flakes to the marinade.
• Don’t Overcrowd the Pan: If your skillet isn’t large enough to accommodate all four mushrooms at once, cook them in batches to ensure even grilling.
• Press Gently: During grilling, you can gently press down on the mushrooms with a spatula to help release excess moisture and encourage browning.
• Grilled Buns: Lightly toast the hamburger buns on the grill for a few seconds per side to add a smoky flavor and prevent them from becoming soggy.
• Stem Savvy: Don’t discard the mushroom stems! They can be chopped and sautéed with onions and garlic for a delicious addition to pasta sauces, soups, or omelets.
• Cheese Please: If you’re not strictly vegetarian, consider melting a slice of provolone, Swiss, or mozzarella cheese over the mushrooms during the last minute of grilling.
• Veggie Variety: Add grilled onions, bell peppers, or zucchini to your portabella mushroom burger for extra flavor and texture.

Serving & Storage Suggestions:

Serve the grilled portabella mushroom burgers immediately while they are hot and juicy. They are best enjoyed fresh off the grill.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, wrap the burger in foil and warm it in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until heated through. You can also reheat them in a skillet over medium heat. Microwaving is not recommended, as it can make the mushrooms rubbery.

While not ideal, you can freeze cooked mushrooms. Allow them to cool completely, wrap them tightly in plastic wrap, and then place them in a freezer-safe bag. They can be stored in the freezer for up to 2 months. When ready to use, thaw them overnight in the refrigerator and reheat as described above. Be aware that the texture may be slightly altered after freezing.

FAQs (Frequently Asked Questions):

Q: Do I need to remove the gills from the portabella mushrooms?
A: Removing the gills is optional. Some people find they can make the mushrooms slightly bitter. If you prefer, you can gently scrape them out with a spoon.

Q: Can I grill these on an outdoor grill instead of a skillet?
A: Absolutely! Preheat your grill to medium heat and grill the mushrooms for about 5-7 minutes per side, or until tender. Watch carefully to prevent burning.

Q: How do I prevent the mushrooms from becoming soggy?
A: Avoid over-marinating the mushrooms, as this can cause them to absorb too much liquid. Also, make sure the skillet is hot enough before adding the mushrooms.

Q: Can I use other types of mushrooms for this recipe?
A: While portabella mushrooms are ideal due to their size and texture, you can experiment with other large mushrooms, such as king oyster mushrooms or large cremini mushrooms.

Q: What are some good side dishes to serve with these burgers?
A: These burgers pair well with classic barbecue sides such as coleslaw, potato salad, corn on the cob, or a simple green salad.
