1 . Stage

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.

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.

Place patties on toasted rye bread. Top with warm onions, Dijon mustard, and remaining bread.
