Ingredients
Scale
For the Caramelized Onions:
- 2 large yellow onions, thinly sliced (about 500 g)
- 2 tablespoons (30 g) unsalted butter
- 1 tablespoon (15 ml) olive oil
- ½ teaspoon salt
- ½ teaspoon sugar (optional, to enhance caramelization)
For the Burgers:
- 1 ½ pounds (680 g) ground beef (preferably 80% lean)
- 1 teaspoon salt
- ½ teaspoon freshly ground black pepper
- ½ teaspoon garlic powder (optional)
Optional Toppings:
- Sliced cheese (cheddar, Swiss, or provolone)
- Lettuce, tomato, pickles, or other toppings of your choice
- Burger buns or lettuce wraps
Instructions
- Caramelize the onions: In a large skillet, melt butter and olive oil over medium heat. Add sliced onions and sprinkle with salt (and sugar if using). Cook, stirring occasionally, for 25–30 minutes, until soft, golden-brown, and sweet. Set aside.
- Prepare the patties: In a bowl, mix ground beef with salt, pepper, and garlic powder until just combined. Divide into 4 equal portions and shape into ¾-inch thick patties, pressing an indentation in the center of each.
- Cook the burgers: Heat a skillet over medium-high heat. Cook patties about 4–5 minutes per side, until desired doneness (160°F / 71°C for medium). Add cheese in the last minute if desired.
- Assemble & serve: Place patties on buns or lettuce wraps, top with caramelized onions and additional toppings, and serve immediately.
Notes
- For leaner burgers: Swap beef for ground turkey or chicken.
- Make-ahead: Caramelized onions can be made up to 5 days in advance and stored refrigerated.
- Gluten-free: Use gluten-free buns or serve wrapped in lettuce.
- Flavor boost: Add sautéed mushrooms or roasted peppers as toppings.
- Storage: Refrigerate cooked patties up to 3 days, or freeze up to 3 months.
