Hamburguesas con Cebolla Caramelizada

Ingredientes

• 1 pound ground beef
• 1 Tablespoon Worcestershire sauce
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 2 large white onions (thinly sliced)
• 2 Tablespoons olive oil
• 1/3 cup light brown sugar
• 1/2 cup beef broth
• 1 Tablespoon Worcestershire sauce
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 4 hamburger buns
• 4 slices cheese

Preparación

1. 1

   Heat a large skillet over medium heat. Add the olive oil, swirling to coat the pan. Add the onions and brown sugar. Stir to evenly coat the onions. Cook for about 45 minutes, stirring frequently, until the onions are cooked down, tender, and a deep golden brown color. You want them to be a deep brown color from the sugars, not from a high heat that sears the onions.

2. 2

   Once cooked down, stir in the beef broth and Worcestershire sauce, increase heat to medium high. Cook until the liquid is absorbed. Season with salt and pepper.

3. 3

   Meanwhile, in a large bowl combine all of the ingredients for the hamburgers. Mix well, and form into 4 equal size patties.

4. 4

   Preheat grill to medium high heat. Place patties on the grill, and cook for 5-6 minutes per side. Place slices of cheese on each burger during the last 2 minutes of cooking. If you would like the buns toasted, place them on the grill during the last 2 minutes of cooking as well.

5. 5

   To serve top, each bun with a cheeseburger patty, a slice of bacon, and about ¼ cup of the caramelized onion mixture.
