To prepare a the labor day burger recipe, you'll need: 1 pound ground beef 2 tbsp ketchup 1 cup mayonnaise 2 tablespoons Worcestershire sauce 1 tablespoon paprika Instructions: Preheat the oven to 450 degrees F. Line 2 large rimmed baking sheets with foil. Heat the oil over medium-high heat until shimmering. Add the onion and cook until softened, about 5 minutes. Stir in the garlic and season with salt and pepper. Cook, stirring occasionally, until the onions are translucent, 2 to 3 minutes longer. Remove the foil and set aside. Cut the beef into 1/4-inch thick slices. Place the slices on the oiled foil-lined baking sheet. Bake, uncovered, for 12 to 15 minutes, or until browned and cooked through. Serve warm with your choice of toppings.
