Ingredients:
- 1 lb lean ground beef
- 1 medium yellow onion, finely diced
- 3 cloves garlic, minced
- 1 tbsp olive oil
- 3/4 cup ketchup
- 1/4 cup tomato sauce
- 1 tbsp brown sugar, packed
- 1 tbsp yellow mustard
- 1 tsp Worcestershire sauce
- 1/2 tsp salt
- 1/4 tsp black pepper
- 6 hamburger buns
- 2 tbsp unsalted butter, softened
Instructions:
- Heat olive oil in a 12 inch skillet over medium high heat. Add ground beef, breaking it into small crumbles, and cook until browned and liquid has evaporated. Note: Don't rush this; the browning is where the flavor lives.
- Add diced onions and garlic to the beef and sauté until onions are translucent and fragrant. Note: The beef fat will help the onions soften beautifully.
- Stir in ketchup, tomato sauce, brown sugar, mustard, and Worcestershire sauce. Lower heat to medium low.
- Simmer uncovered for 10-12 minutes until the sauce is thick and glossy. Note: Stir occasionally so the bottom doesn't scorch.
- Spread butter on the cut side of the hamburger buns.
- Toast buns in a separate pan or under a broiler for 60-90 seconds until golden brown.
- Spoon the beef mixture onto the toasted buns.
- Serve immediately while the buns are still warm and crisp.
