In a large skillet over medium heat brown the ground beef with onion and red pepper. Sprinkle salt and pepper over top. Drain any grease from the meat mixture. Add garlic the last minute of cooking.
Add in ketchup, brown sugar, mustard and Worcestershire sauce. Season with salt and black pepper to taste. Cover and simmer on low for 10-20 minutes, stirring occasionally. Add more ketchup or water if you need more liquid.
Serve warm on fresh hamburger buns.
Notes
Hamburger buns: We love to use brioche buns or make homemade hamburger buns.To toast your hamburger buns, heat 1-2 Tablespoons of butter on a griddle over medium heat. Then place the hamburger buns on and cook 1-3 minutes, or until the bottoms are lightly toasted. This will add great flavor and prevent the buns from getting soggy. Tomato sauce: If you prefer to use tomato sauce, you can swap it for the ketchup to make it less sweet. Add in extra seasonings to taste. Storage: Store leftovers in a covered airtight container for up to 3 days. Freeze in a zip top bag up to 3 months.
