A flavorful and juicy vegan burger featuring grilled portobello mushrooms marinated in a smoky, tangy sauce and topped with a fresh avocado spread. Perfect for quick, easy, and satisfying cookouts.

Ingredients

Scale
  • 4 large portobello mushroom caps, cleaned and stems removed
  • 3 tablespoons extra virgin olive oil
  • 2 tablespoons soy sauce or tamari (tamari for gluten-free option)
  • 1 tablespoon balsamic vinegar
  • 2 cloves garlic, minced
  • 1 teaspoon smoked paprika
  • ½ teaspoon freshly cracked black pepper
  • ¼ teaspoon sea salt
  • 2 medium ripe avocados, peeled and pitted
  • 1 tablespoon freshly squeezed lime juice
  • 2 tablespoons fresh cilantro, chopped (optional)
  • ¼ cup thinly sliced red onion (for topping)
  • 4 whole grain or gluten-free burger buns, toasted
  • Optional toppings: lettuce leaves, tomato slices, pickles

Instructions

  1. Prepare the marinade by whisking together olive oil, soy sauce or tamari, balsamic vinegar, minced garlic, smoked paprika, black pepper, and sea salt in a medium bowl.
  2. Place the cleaned portobello caps in the bowl or a shallow dish and coat both sides generously with the marinade using a brush or spoon. Cover and let sit at room temperature for at least 20 minutes, flipping halfway through.
  3. While mushrooms marinate, make the avocado spread by mashing avocado flesh with lime juice, chopped cilantro, and a pinch of salt until creamy but slightly chunky. Adjust seasoning as needed.
  4. Preheat grill or grill pan to medium-high heat (about 400°F / 200°C).
  5. Grill the marinated portobello caps gill side down first for 5-7 minutes per side until tender with visible char marks, brushing with olive oil or leftover marinade if they start to dry out.
  6. Toast the burger buns lightly on the grill or in a toaster oven.
  7. Assemble the burgers by spreading avocado mixture on the bottom bun, adding the grilled portobello cap, then topping with red onion, lettuce, tomato, or other favorite toppings. Cap with the top bun and serve immediately.

Notes

Marinate mushrooms for at least 20 minutes or up to 2 hours for best flavor. Use ripe avocados for creamy spread and add lime juice to prevent browning. If no grill is available, use a grill pan or cast iron skillet over medium-high heat. Mushrooms shrink when cooked, so expect smaller size after grilling. Toast buns last to keep them warm and crisp.
