Ingredients

• 4 large caps Portobello mushrooms
• 4 tablespoons Olive oil
• 2 tablespoons Balsamic vinegar
• 2 cloves, minced Garlic
• 2 tablespoons Soy sauce
• 1.5 tablespoons Dijon mustard
• 0.25 cup Mayonnaise
• 1 teaspoon Lemon juice
• 4 Hamburger buns
• 4 Lettuce leaves
• 4 Tomato slices
• 4 Red onion slices
• 0.5 teaspoon Salt
• 0.25 teaspoon Black pepper

Directions

Step 1

Clean the portobello mushroom caps by gently removing the stems and wiping the caps with a damp paper towel to remove any dirt. Set aside.

Step 2

In a small bowl, whisk together 3 tablespoons olive oil, balsamic vinegar, minced garlic, soy sauce, salt, and black pepper to create the marinade.

Step 3

Place the portobello mushroom caps in a shallow dish or zip-top bag. Pour the marinade over the mushrooms, ensuring each cap is evenly coated. Let them marinate at room temperature for about 15 minutes, turning occasionally.

Step 4

While the mushrooms are marinating, prepare the creamy Dijon sauce. In a small bowl, whisk together mayonnaise, Dijon mustard, 1 tablespoon olive oil, and lemon juice until smooth. Set aside.

Step 5

Preheat your grill or grill pan over medium-high heat. Lightly oil the grates to prevent sticking.

Step 6

Remove the mushrooms from the marinade and place them on the preheated grill. Cook for 4-5 minutes on each side, or until tender and slightly charred. Reserve any leftover marinade and brush it over the mushrooms during grilling for extra flavor.

Step 7

While the mushrooms are grilling, lightly toast the hamburger buns on the grill for about 1-2 minutes, or until golden brown.

Step 8

Assemble the burgers by spreading a generous layer of creamy Dijon sauce on the bottom half of each toasted bun. Place a grilled portobello mushroom cap on top, followed by a lettuce leaf, a slice of tomato, and a slice of red onion. Add the top bun to complete the burger.

Step 9

Serve immediately and enjoy your flavorful Grilled Portobello Burgers with Creamy Dijon Sauce!
