Heat a large skillet on medium heat. Add ground beef and cook slowly. Break it into small pieces. Cook until browned fully. Drain extra fat to keep the dish light.

Add chopped onion and bell pepper to the beef. Stir well and cook for five minutes. The vegetables should become soft and release a nice aroma while cooking.

Add minced garlic and cook for one minute. Now add ketchup, tomato paste, and Worcestershire sauce. Stir everything well so the mixture becomes smooth and rich.

Add brown sugar, mustard, salt and black pepper. Mix again and let it simmer for five minutes. The sauce will thicken and coat the beef nicely.

Preheat oven to 180°C (350°F). Lightly grease a baking dish. Pour the beef mixture into it. Spread evenly so every bite has balanced flavor and texture.

Cut biscuit dough into small pieces. Place them evenly over the meat mixture. Leave small spaces between pieces so they cook evenly and become golden.

Sprinkle shredded cheddar cheese over the biscuit layer. Cover all areas evenly. This helps create a gooey, cheesy top that melts beautifully during baking.

Place the dish in the oven. Bake for 25 to 30 minutes. The biscuits should rise and turn golden brown. The cheese should melt and bubble nicely.

Remove from oven and let it rest for five minutes. This helps the casserole set properly. Serve warm and enjoy a comforting homemade sloppy joe bake.
