Ingredients

Instructions

  1. Step 1: Mix 1 lb ground beef with 1/2 tsp salt and 1/4 tsp black pepper; form into 4 patties, 3/4 inch thick, pressing a slight indentation in the center.
  2. Step 2: Heat a skillet over medium-high, add patties, and cook for 3-4 minutes per side for medium doneness (internal temp 160°F), flipping once.
  3. Step 3: While burgers cook, melt 1 tbsp butter in a saucepan, add 1/4 cup finely chopped yellow onion, and cook for 8-10 minutes until golden, stirring occasionally.
  4. Step 4: Stir 2 tbsp all-purpose flour into onions, cook 1 minute, then whisk in 1/4 cup beef broth and 2 tbsp ketchup; simmer 2 minutes until sauce thickens and coats the back of a spoon.
  5. Step 5: Place each patty on a toasted bun, top with 1 slice cheddar (allowing it to melt on the hot patty), and spoon caramelized onion sauce over the cheese.
