Ingredients

• 4 large portobello mushroom caps, stems removed and gills scraped
• 3 tbsp olive oil
• 2 tbsp balsamic vinegar
• 2 tsp soy sauce (or tamari for gluten-free)
• 2 cloves garlic, minced
• 1 tsp dried oregano
• ½ tsp smoked paprika
• Salt and black pepper, to taste
• 4 burger buns (use gluten-free if needed)
• 1 ripe avocado, sliced
• 4 slices tomato
• 4 leaves lettuce (romaine or iceberg)
• ½ red onion, thinly sliced
• 4 tbsp mayonnaise or vegan mayo
• 2 tsp Dijon mustard

Instructions

1. In a small bowl, whisk together olive oil, balsamic vinegar, soy sauce, minced garlic, oregano, smoked paprika, salt, and pepper.

2. Brush the marinade over both sides of the portobello caps. Let them marinate for 10-15 minutes while you prepare the toppings and preheat your grill (or grill pan) to medium-high heat.

3. Grill the mushrooms, cap side down first, for 4–5 minutes per side, until tender and slightly charred.

4. Toast burger buns lightly on the grill, if desired.

5. Spread mayonnaise and Dijon mustard on the bottom half of each bun. Layer with lettuce, grilled portobello, tomato slice, avocado slices, and red onion. Top with remaining bun half.

6. Serve immediately with your favorite side dishes.

Zusatztipps für die Zubereitung

Make sure to scrape out the gills of the portobello mushrooms to prevent bitterness. Allowing the mushrooms to marinate the full 15 minutes enhances their flavor. Grill them over medium-high heat for the perfect char without overcooking.

Varianten und Anpassungen

For a cheesier version, add a slice of your favorite cheese during the last minute of grilling. Swap mayonnaise for hummus to add a different creamy texture, or include pickled jalapeños for extra heat. Use gluten-free buns to accommodate dietary preferences.

Serviervorschläge

These burgers go great with sweet potato fries or a fresh green salad for a well-rounded meal. Serve immediately to enjoy the best texture and flavor of the grilled mushrooms and fresh toppings.
