Recipe Instructions
Step 1
Mix sirloin, Worcestershire sauce, garlic, salt, and pepper together by hand in a medium bowl. Form into 4 hamburger patties and wrap in plastic wrap. Place in the refrigerator until flavors have melded, 4 hours to overnight.
Step 2
Heat butter and olive oil in a large skillet over medium heat until melted. Add onions and saute until they begin to caramelize, about 15 minutes, reducing heat to medium-low if they seem to be sizzling too much.
Step 3
Spray a large skillet with cooking spray and heat over medium heat. Place hamburger patties in the skillet and cook for 3 minutes per side, topping each patty with a slice of Cheddar cheese after flipping.
Step 4
Place patties on toasted rye bread. Top with warm onions, Dijon mustard, and remaining bread.
