Ingredients:
- 1 lb (450 g) ground chuck (80/20 blend)
- 1 teaspoon (5 g) salt
- 1/2 teaspoon (2 g) black pepper
- 1 tablespoon (15 ml) Worcestershire sauce
- 4 slices of cheddar cheese (optional)
- 2 large yellow onions, sliced (about 2 cups)
- 2 tablespoons (30 ml) olive oil
- 1 teaspoon (5 g) sugar
- Salt, to taste
- 4 burger buns
- Lettuce, tomato, pickles, and any preferred condiments
Instructions:
- Heat olive oil in a skillet over medium heat. Add sliced onions, sprinkle with sugar and salt, and stir. Cook for 25-30 minutes, stirring occasionally, until deep gold and caramelized.
- In a bowl, combine ground chuck, salt, pepper, and Worcestershire sauce. Gently mix until combined, then divide into 4 equal portions and form into patties.
- Preheat the grill or skillet to medium-high. Cook the patties for 4-5 minutes on one side, flip, and add cheese if using. Cook for another 3-5 minutes for medium doneness or until internal temperature reaches 160°F (71°C).
- Toast the burger buns if desired. Layer lettuce, the cooked patty, caramelized onions, and additional toppings before closing the bun.
- Enjoy the burgers immediately with your choice of sides!
