Ingredients:
- 1 1/2 lbs ground beef
- 2 large onions, thinly sliced
- 2 tbsp butter
- 1 tbsp olive oil
- 1 tsp sugar
- 1 tsp balsamic vinegar
- 4 slices Gruyère or Swiss cheese
- 4 burger buns, toasted
- 1 tbsp Dijon mustard (optional)
- Salt and pepper to taste
- Fresh thyme for garnish (optional)
Instructions:
- Caramelize the onions: In a large skillet, heat butter and olive oil over medium heat. Add the sliced onions and cook for 10 minutes. Sprinkle with sugar and continue cooking, stirring occasionally, until the onions are golden brown and caramelized, about 20-25 minutes. Stir in balsamic vinegar, salt, and pepper. Set aside.
- Prepare the beef patties: Divide the ground beef into 8 equal portions. Flatten each portion into thin patties. On 4 of the patties, place a spoonful of caramelized onions and a slice of Gruyère cheese. Top with the remaining patties, pressing the edges together to seal.
- Cook the burgers: Heat a grill or skillet over medium-high heat. Season the burgers with salt and pepper. Cook the stuffed patties for 4-5 minutes per side, or until they are cooked to your desired doneness and the cheese is melted inside.
- Assemble the burgers: Spread Dijon mustard (if using) on the toasted buns. Place the stuffed burger on the bottom bun, top with additional caramelized onions, and garnish with fresh thyme if desired. Add the top bun and serve.
This Stuffed French Onion Soup Burger is a savory, indulgent meal that combines the best of both worlds—perfect for anyone who loves the deep flavors of French onion soup and a juicy burger!
