Ingredients
Scale
For the Caramelized Onions:
- 2 large yellow onions, thinly sliced
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1/2 teaspoon sugar
- 1/4 teaspoon salt
- 1/4 cup beef broth
For the Burgers:
- 1 ½ lbs ground beef
- 1 teaspoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 4 slices Gruyère or Swiss cheese
For Assembling:
- 4 brioche or hamburger buns
- 2 tablespoons mayonnaise
- Optional toppings: Arugula, spinach, or lettuce
Instructions
Step 1: Caramelize the Onions
- Heat the butter and olive oil in a large skillet over medium heat.
- Add the sliced onions, sugar, and salt. Cook for 25-30 minutes, stirring occasionally, until the onions are deeply golden and caramelized.
- Deglaze the pan by adding the beef broth, scraping up any browned bits. Cook until the liquid is absorbed. Remove from heat and set aside.
Step 2: Make the Burger Patties
- In a mixing bowl, combine the ground beef, Worcestershire sauce, garlic powder, onion powder, salt, and black pepper. Mix gently until combined.
- Divide the mixture into four equal portions and shape into patties.
Step 3: Cook the Burgers
- Preheat a grill or stovetop pan over medium-high heat. Lightly oil the surface.
- Cook the patties for 4-5 minutes on each side, or until they reach your desired doneness.
- In the last minute of cooking, place a slice of cheese on each patty and cover with a lid to melt.
Step 4: Assemble the Burgers
- Toast the brioche buns lightly for extra flavor.
- Spread mayonnaise on the bottom bun, add the patty with melted cheese, and top with a generous heap of caramelized onions.
- Add optional toppings like arugula or spinach, then crown with the top bun.
Notes
- Choose the Right Beef: Use ground beef with 80/20 fat for juicy patties.
- Don’t Rush the Onions: Slow-cooking is key to achieving rich caramelization.
- Customize the Cheese: Gruyère is classic, but Swiss, provolone, or even mozzarella works well.
- Toast the Buns: It adds flavor and prevents them from getting soggy.
