Ingredients

• 4 pieces Portabella mushrooms (large)
• 4 tablespoons Olive oil
• 2 tablespoons Balsamic vinegar
• 2 cloves Garlic cloves, minced
• 2 teaspoons Soy sauce
• 1 teaspoon Fresh rosemary, chopped
• 0.5 teaspoon Salt
• 0.5 teaspoon Black pepper
• 4 pieces Wheels of brie cheese (about 1.5 oz. each)
• 4 pieces Brioche buns
• 2 tablespoons Butter
• 1 large Yellow onion, thinly sliced
• 1 teaspoon Brown sugar
• 2 cups Arugula
• 1 large Tomato, sliced

Directions

Step 1

Clean the portabella mushrooms by gently brushing off any dirt with a damp paper towel. Remove the stems and scrape out the gills using a spoon.

Step 2

In a small bowl, whisk together olive oil, balsamic vinegar, garlic, soy sauce, rosemary, salt, and pepper to make the marinade.

Step 3

Place the mushrooms in a shallow dish and pour the marinade over them. Let them marinate for at least 10 minutes, turning occasionally.

Step 4

While the mushrooms marinate, heat butter in a skillet over medium heat. Add the sliced onions and cook for 10-12 minutes, stirring occasionally, until caramelized. Add the brown sugar in the final few minutes of cooking and stir well. Set the onions aside.

Step 5

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

Step 6

Place the marinated mushrooms on the grill, gill side down, and cook for 5 minutes. Flip them and cook for an additional 4-5 minutes, or until they are tender and have nice grill marks.

Step 7

During the last minute of grilling the mushrooms, place a wheel of brie cheese on top of each mushroom cap to slightly soften and melt.

Step 8

Toast the brioche buns on the grill or in a toaster until lightly golden.

Step 9

Assemble the burgers by spreading a thin layer of butter or a preferred condiment on the bottom bun. Layer arugula, a grilled mushroom cap with melted brie, caramelized onions, a slice of tomato, and then the top bun.

Step 10

Serve warm and enjoy your Grilled Portabella and Brie Burgers!
