Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or a thin layer of oil.

Step 2: Cook the Ground Beef

In a large skillet over medium-high heat, add the olive oil (if needed) and ground beef. Cook for 5-7 minutes, breaking it apart with a spatula, until fully browned. Drain excess fat.

Step 3: Sauté Vegetables

Add the chopped onion and green bell pepper to the skillet with the ground beef. Sauté until soft—about 4-5 minutes.

Step 4: Mix Everything Together

In a large mixing bowl, combine the cooked beef mixture with baked beans, barbecue sauce, ketchup, mustard, brown sugar, Worcestershire sauce, and spices. Stir until everything is well mixed and evenly coated.

Step 5: Bake to Perfection

Pour the mixture into the prepared baking dish and spread evenly. If using cheese or bacon bits, sprinkle them on top. Bake uncovered for 30–35 minutes until bubbly and slightly caramelized on the top.
