Ingredients and Quantities
For the Onions:
- 2 large onions, thinly sliced
- 2 tbsp unsalted butter
- 1 tbsp olive oil
- 1/4 tsp salt
- 1 tsp sugar (optional, to enhance caramelization)
- 1/4 cup beef broth
- 1/4 tsp thyme (optional)
For the Burgers:
- 1 lb (450 g) ground beef (80/20 mix preferred for juiciness)
- 1 tsp Worcestershire sauce
- 1/2 tsp garlic powder
- Salt and pepper, to taste
- 4 slices Gruyere or Swiss cheese
For Assembly:
- 4 brioche or hamburger buns, toasted
- 1/4 cup mayonnaise
- 1 tbsp Dijon mustard (optional)
- Fresh parsley for garnish (optional)
Tips for Success
- Caramelize with patience: Cook onions over low heat to achieve deep, sweet caramelization.
- Juicy patties: Avoid overmixing the ground beef to keep the burgers tender and juicy.
- Toasted buns: Lightly toasting the buns adds flavor and prevents sogginess.
How to Make and Instructions
Caramelized Onions:
- Heat butter and olive oil in a skillet over medium heat. Add sliced onions and sprinkle with salt and sugar (if using).
- Cook onions, stirring occasionally, for 20-30 minutes until deep golden brown. Add beef broth and thyme, stirring until the liquid is absorbed. Set aside.
Burgers:
- In a bowl, mix ground beef with Worcestershire sauce, garlic powder, salt, and pepper. Form into 4 patties.
- Heat a skillet or grill over medium-high heat. Cook patties for 3-4 minutes per side, topping each with Gruyere cheese during the last minute of cooking to melt.
Assemble the Burgers:
- Mix mayonnaise and Dijon mustard (if using) and spread on toasted buns.
- Place the beef patty on the bottom bun. Top with a generous scoop of caramelized onions.
- Add the top bun and garnish with fresh parsley if desired.
