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.
In a small bowl, whisk together olive oil, balsamic vinegar, garlic, soy sauce, rosemary, salt, and pepper to make the marinade.
Place the mushrooms in a shallow dish and pour the marinade over them. Let them marinate for at least 10 minutes, turning occasionally.
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.
Preheat your grill or grill pan to medium heat. Lightly oil the grates to prevent sticking.
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.
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.
Toast the brioche buns on the grill or in a toaster until lightly golden.
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.
Serve warm and enjoy your Grilled Portabella and Brie Burgers!
