Juicy Beef Burger with Caramelized Onions

1Heat a skillet over medium heat and add a drizzle of oil.

2Form the ground beef (1 lb) into 4 patties and season with salt and pepper.

3Cook the beef patties in the skillet for about 4-5 minutes per side, or until fully cooked through.

4In a separate skillet, caramelize the sliced onions over low heat until golden brown and sweet, about 10 minutes.

5When the patties are almost done, top each patty with a slice of cheese and cover the skillet to allow the cheese to melt.

6Toast the burger buns (4) in the skillet until lightly golden and warm.

7Assemble the burgers by placing lettuce leaves on the bottom bun, followed by a beef patty with melted cheese, caramelized onions, tomato slices, and the top bun.

8Serve hot and enjoy the delicious Juicy Beef Burger with Caramelized Onions!
