Directions

• Divide the ground beef into equal portions, about 4 ounces each. Shape each portion into a loosely packed ball.
• Heat a large skillet or griddle over high heat until it's smoking hot.
• Place a ball of beef on the skillet and use a metal spatula or burger press to smash it down until it's about 1/4-inch thick.
• Sprinkle 1 tablespoon of minced onion on top of each patty.
• Cook the patties for about 1-2 minutes, until a deep brown crust forms on the bottom.
• Scrape, then flip the patties over and immediately place a slice of cheese on top of each patty.
• Cook for an additional 1-2 minutes, until the cheese is melted and the burgers are cooked to your desired level of doneness.
• While the burgers are cooking, place the bacon in a separate skillet and cook until crispy. Remove the bacon and place it on a paper towel to drain, reserving the bacon fat in the skillet.
• Use the bacon fat to toast the hamburger buns until golden brown and crispy.
• To make the burger sauce, mix together the mayonnaise, ketchup, mustard, and Worcestershire sauce in a small bowl.
• Assemble the burgers by placing a patty on the bottom bun, adding a dollop of burger sauce, a few slices of crispy bacon, and any other desired toppings and condiments. Add the top bun.
