Ingredients

• 1 lb Ground beef (80/20 blend)
• 1 tsp Salt
• 0.5 tsp Black pepper
• 1 tbsp Worcestershire sauce
• 2 large Yellow onion
• 2 tbsp Butter
• 1 tbsp Olive oil
• 1 tsp Granulated sugar
• 4 pieces Burger buns
• 4 pieces Cheese slices (optional, cheddar or American)
• 4 pieces Lettuce leaves
• 4 pieces Tomato slices
• 4 tbsp Mayonnaise

Directions

Step 1

Thinly slice the onions into even rounds.

Step 2

Heat a large skillet over medium heat and add the butter and olive oil.

Step 3

Once the butter is melted, add the sliced onions and stir to coat them in the fat.

Step 4

Sprinkle the onions with granulated sugar and a pinch of salt. This helps enhance their sweetness and aids in caramelization.

Step 5

Reduce the heat to low and cook the onions, stirring occasionally, for 25–30 minutes until they are deep golden brown and soft. Set aside.

Step 6

In a large mixing bowl, combine the ground beef, salt, black pepper, and Worcestershire sauce. Mix gently until just combined, being careful not to overwork the meat.

Step 7

Divide the beef mixture into 4 equal portions and shape each into a patty, about ¾-inch thick. Use your thumb to create a small indentation in the center of each patty to prevent them from puffing up during cooking.

Step 8

Heat a grill or skillet over medium-high heat. Cook the burger patties for about 3–4 minutes per side for medium doneness, or longer if desired. During the last minute of cooking, place a cheese slice on each patty (if using) to melt.

Step 9

Toast the burger buns lightly on the grill or in a toaster for added flavor and texture.

Step 10

Assemble the burgers by spreading 1 tablespoon of mayonnaise on the bottom half of each bun.

Step 11

Layer with a lettuce leaf, a cooked burger patty, caramelized onions, and a tomato slice. Top with the other half of the bun.

Step 12

Serve warm with your favorite sides, such as fries or a fresh salad.
