Step 1: Cook the Ground Beef

Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a wooden spoon, until browned. Drain excess grease if needed to prevent the sauce from becoming too oily.

Step 2: Sauté the Vegetables

Add the chopped onion, green bell pepper, and garlic to the skillet. Cook for about 3-5 minutes until softened and fragrant. Stir occasionally to ensure even cooking and prevent burning.

Step 3: Add the Sauce Ingredients

Stir in the tomato sauce, ketchup, tomato paste, Worcestershire sauce, brown sugar, mustard, smoked paprika, chili powder, salt, black pepper, and red pepper flakes. Mix well until everything is evenly combined and the sauce starts to thicken.

Step 4: Simmer the Mixture

Pour in the water or beef broth and stir to combine. Lower the heat and let the mixture simmer for 10-15 minutes until the sauce thickens and coats the beef well. Stir occasionally to prevent sticking and ensure even cooking.

Step 5: Toast the Buns & Serve

If desired, spread butter on the inside of the buns and toast them on a skillet until golden. Spoon the Sloppy Joe mixture onto the buns and serve immediately. Garnish with pickles, cheese, or extra condiments if preferred.
