Instructions

Melt butter and olive oil in a large dutch oven over medium heat. Add sliced onions and cover, cooking for 10 minutes until they start to wilt. Remove lid, lower heat, add thyme, salt, and pepper. Continue cooking until deeply caramelized; stir in dijon mustard and balsamic vinegar, then set aside.
Finely chop half of the cooled caramelized onions and combine in a large bowl with ground beef, Worcestershire sauce, dijon mustard, dehydrated onion, garlic powder, salt, and pepper. Mix gently and form into 4 patties, each at least 1 inch thick with an indentation in the center.
Mix mayo, dijon, horseradish, and honey in a small bowl; season with salt and cracked black pepper.
Preheat your grill to 450°F. Clean and lightly oil the grates to prevent sticking.
Grill the burger patties over direct heat for 3-4 minutes on each side. Remove from grill and rest, topping with slices of brie while warm.
Spread burger sauce on toasted buns, add burger patties, top with remaining caramelized onions and arugula. Serve immediately.

Notes

Use a mandolin for even slicing of the onions for better caramelization.
You can substitute the brie cheese with another soft cheese if desired.
Grilling times may vary based on grill type, so check for desired doneness.
