Ingredients

• 4 pieces Portabella mushroom caps
• 3 tablespoons Olive oil
• 2 tablespoons Balsamic vinegar
• 1 tablespoon Soy sauce
• 2 cloves Garlic
• 1 cup Mayonnaise
• 1 tablespoon Lemon juice
• 0.5 teaspoon Salt
• 0.25 teaspoon Black pepper
• 4 pieces Hamburger buns
• 4 leaves Lettuce
• 1 large Tomato
• 0.5 medium Red onion

Directions

Step 1

Clean the portabella mushroom caps, removing the stems and gently scraping out the gills with a spoon if desired.

Step 2

In a small bowl, whisk together 3 tablespoons of olive oil, 2 tablespoons of balsamic vinegar, 1 tablespoon of soy sauce, and 1 minced garlic clove. Season with a pinch of salt and black pepper.

Step 3

Place the mushroom caps in a shallow dish and pour the marinade over them, ensuring they are evenly coated. Allow them to marinate for 15–20 minutes.

Step 4

While the mushrooms are marinating, prepare the aioli. In another bowl, combine 1 cup of mayonnaise, 1 minced garlic clove, 1 tablespoon of lemon juice, 0.5 teaspoons of salt, and 0.25 teaspoons of black pepper. Mix well and set aside.

Step 5

Preheat a grill or grill pan over medium heat. Lightly oil the surface to prevent sticking.

Step 6

Grill the marinated mushroom caps for 5–7 minutes per side, or until tender and slightly charred.

Step 7

Slice the tomato and red onion into thin rounds.

Step 8

Toast the hamburger buns lightly on the grill or in a toaster if desired.

Step 9

Assemble the burgers by spreading a generous amount of aioli on the bottom half of each bun. Layer with a grilled mushroom cap, a leaf of lettuce, a slice of tomato, and a few rings of red onion. Top with the other half of the bun.

Step 10

Serve immediately and enjoy your delicious Portabella Burger with Aioli.
