Ingredients
Scale1x2x3x
- 1 lb (450 g) ground beef, 80/20 blend
- 1 tsp kosher salt
- ½ tsp freshly ground black pepper
- 1 tsp garlic powder
- 1 tsp Worcestershire sauce
- 3 large yellow onions, thinly sliced
- 2 tbsp unsalted butter
- 1 tbsp olive oil
- 2 tbsp brown sugar
- 2 tbsp balsamic vinegar
- ½ tsp salt
- Freshly ground black pepper to taste
- 4 brioche burger buns
- 4 slices sharp cheddar cheese (optional)
- Fresh lettuce leaves
- Tomato slices
- Dill pickles
- Mayonnaise or your favorite burger sauce
Instructions
- Make the Caramelized Onion Jam: Heat butter and olive oil in a skillet over medium-low heat. Add sliced onions and stir to coat. Cook slowly, stirring occasionally, until onions soften and turn deep golden brown (about 25-30 minutes). Halfway through, sprinkle in brown sugar and salt. Once browned, stir in balsamic vinegar and cook for another 2-3 minutes until jammy. Remove from heat and set aside.
- Prepare the Burger Patties: In a mixing bowl, combine ground beef, salt, pepper, garlic powder, and Worcestershire sauce. Mix gently but thoroughly. Divide into 4 equal portions (about 4 oz each) and shape into patties slightly wider than buns. Make a small indentation in the center of each patty with your thumb.
- Cook the Burgers: Heat a grill pan or skillet over medium-high heat. Cook patties for 3-4 minutes per side for medium doneness. Add cheese slices in the last minute and cover loosely to melt. Use an instant-read thermometer to check for 160°F internal temperature.
- Toast the Buns: While burgers cook, lightly toast brioche buns on the grill or in a toaster oven until golden and slightly crisp.
- Assemble the Burgers: Spread mayonnaise or preferred sauce on bottom bun, add lettuce leaf, burger patty with melted cheese, a generous spoonful of caramelized onion jam, tomato slices, and pickles. Top with the bun.
- Serve Immediately: Enjoy hot with your favorite sides.
