# How To Cook:

01 - Heat olive oil and butter in a large skillet over medium heat. Add onions and a pinch of salt. Cook, stirring occasionally, until caramelized and golden brown, about 12–15 minutes.
02 - Add minced garlic and thyme; cook for 1 minute until fragrant.
03 - Push onions to the side of the pan. Add the ground beef to the skillet and break it up with a spatula. Cook until browned and cooked through, about 5–6 minutes. Drain excess fat if needed.
04 - Sprinkle flour over the beef and onions, stirring well to coat. Cook for 1 minute.
05 - Stir in beef broth and Worcestershire sauce. Simmer for 3–4 minutes, until the mixture thickens slightly. Season with salt and pepper to taste.
06 - Toast brioche buns under the broiler or in a skillet until golden.
07 - Spoon the beef and onion mixture onto the bottom half of each bun. Top with a slice of cheese. Place under the broiler for 1–2 minutes until the cheese is melted and bubbly.
08 - Add the top bun and serve hot.
