📝 Instructions

11 steps

1. Clean the portobello mushroom caps by gently wiping them with a damp paper towel. Remove the stems if present.

2. In a small bowl, whisk together olive oil, balsamic vinegar, minced garlic, salt, and black pepper.

3. Brush both sides of each mushroom cap with the olive oil mixture, ensuring they are well coated. Set them aside to marinate for 10 minutes.

4. While the mushrooms are marinating, prepare the avocado mayonnaise. Scoop the flesh of the avocado into a small mixing bowl and mash it until smooth.

5. Add the mayonnaise and lime juice to the mashed avocado. Stir until well combined. Season with a pinch of salt to taste.

6. Heat a grill or grill pan over medium heat. Place the marinated mushroom caps on the grill, gill side down. Cook for 5-6 minutes per side, or until tender and slightly charred.

7. Lightly toast the hamburger buns on the grill during the last 2 minutes of cooking the mushrooms.

8. Assemble the burgers by spreading a generous layer of avocado mayonnaise on the bottom halves of the toasted buns.

9. Place a grilled portobello mushroom cap on top of the avocado mayonnaise, followed by a lettuce leaf, a tomato slice, and a red onion slice.

10. Top with the other half of the bun. Repeat for the remaining burgers.

11. Serve immediately and enjoy your delicious Portobello Burgers with Avocado Mayonnaise!
