Ingredients
Scale
For the Caramelized Onions:
- 3 large yellow or white onions, thinly sliced
- 2 tbsp butter
- 2 tbsp water (plus more as needed)
- 1 tbsp brandy or Sherry (optional)
For the Beef Patties:
- 1 ½ lbs ground beef (80/20 or 85/15)
- 2 tbsp French onion soup mix (store-bought or homemade)
For Assembly:
- 4 brioche buns, toasted
- 4 oz Gruyère cheese, sliced
- Optional toppings: Dijon mustard, fresh thyme
- Optional addition: 4 crispy croutons
Instructions
Prepare the Caramelized Onions:
- In a large skillet, melt butter and water over medium heat. Add sliced onions and cover. Cook for 15-20 minutes, stirring occasionally, until soft and lightly browned.
- Uncover and continue cooking, stirring frequently. Add water as needed to prevent burning. Cook until deep golden brown and caramelized (30-40 minutes).
- Add brandy or Sherry (optional) in the last few minutes for enhanced flavor. Set aside.
Make the Beef Patties:
- In a large bowl, mix ground beef with French onion soup mix. Form into 4 patties with a slight indentation in the center.
- Heat a grill or skillet over medium-high heat. Cook patties for about 3 minutes per side, or until desired doneness. During the last 1-2 minutes of cooking, add a slice of Gruyère cheese to each patty. Cover to melt.
Assemble the Burgers:
- Place the cheese-topped patties on the bottom half of each toasted brioche bun.
- Add a generous portion of caramelized onions on top of the cheese.
- (Optional) Add a crouton under each patty for extra texture.
- Spread Dijon mustard on the top bun or sprinkle with fresh thyme if desired. Top with the bun and serve immediately.
Notes
- Use high-quality ground beef for the juiciest patties.
- Homemade French onion soup mix offers better flavor control.
- Toasting the buns adds texture and prevents sogginess.
- Pair with crispy fries, a green salad, or roasted vegetables.
