Follow these simple steps to create your Black Garlic & Brie-Stuffed Brioche Burger:

1. Prepare the Black Garlic Mixture: In a bowl, combine the ground beef with the mashed black garlic. Season with salt and pepper to taste. Mix gently until just combined to avoid overworking the meat.

2. Form the Patties: Divide the beef mixture into four equal portions. Flatten each portion into a patty, making a small indentation in the center to hold the Brie.

3. Add the Cheese: Place a slice of Brie in the center of each patty. Fold the edges of the meat over the cheese, sealing it inside. Shape the patty back into a round form, ensuring the Brie is completely enclosed.

4. Preheat the Grill or Pan: Heat a grill or a skillet over medium-high heat. Add olive oil to the skillet if using.

5. Cook the Patties: Once hot, add the patties to the grill or skillet. Cook for about 4-5 minutes on one side, then flip and cook for another 4-5 minutes, or until desired doneness is reached. The internal temperature should be 160°F for medium well.

6. Toast the Buns: In the last few minutes of cooking, place the brioche buns on the grill or in the skillet, cut side down, to toast until golden brown.

7. Assemble the Burgers: Once the patties are cooked, let them rest for a few minutes. Then, place each patty on the bottom half of a toasted brioche bun. Top with lettuce, tomato, and any additional toppings like caramelized onions.

8. Serve: Place the top half of the bun over the patty and serve immediately while the Brie is still melty and delicious.
