Sloppy Joe Casserole is a cozy twist on two American classics the hearty flavor of Sloppy Joes layered with a tender cornbread crust. It brings together beefy tomato richness and fluffy cornbread in every bite and is a lifesaver when you need comfort food on the table without fuss. This is one of those dishes my family devours with zero leftovers and it makes weeknight cooking feel easy but still special.
I first whipped this up on a cold weeknight when the fridge was almost bare except for a box of corn muffin mix and some ground beef. Now my kids ask for Sloppy Joe Casserole every time the weather turns chilly.

- Soften Vegetables:
- Add chopped onion and diced green bell pepper to the skillet with beef and cook for about five minutes until veggies are soft but not browned stir often to avoid burning
- Build the Sloppy Joe Sauce:
- Stir in Worcestershire sauce brown sugar mustard ketchup water salt and pepper mix well and let it all simmer gently for five minutes to let the flavors blend and the filling thicken taste and add more water if too thick
- Prepare Cornbread Topping:
- In a mixing bowl combine corn muffin mix milk vegetable oil and egg stir just until combined so the batter is lumpy overmixing will make the cornbread tough set aside
- Assemble in Baking Dish:
- Grease a nine inch square baking dish spread the hot sloppy joe mixture evenly on the bottom then pour the cornbread batter over the top use a spatula to smooth it over the beef but do not push it down into the filling
- Bake to Perfection:
- Bake in a preheated oven at three hundred fifty degrees Fahrenheit for twenty five to thirty five minutes until the top is golden and a toothpick inserted into the center comes out clean watch so it does not overbake
- Add Cheddar Finish:
- Right after the casserole comes out of the oven sprinkle shredded cheddar cheese over the top so it melts from the heat let it sit for a few minutes so the cheese finishes melting and the casserole firms up for easier serving

Storage Tips
Let the casserole cool to room temperature before covering tightly with foil or transferring to an airtight container in the fridge. It stays fresh up to three days and leftovers can be reheated in a low oven to keep the cornbread from drying out. For freezing wrap the entire baked casserole well and freeze up to two months. Thaw overnight in the fridge and reheat covered until hot.
Ingredient Substitutions
Ground turkey or chicken can stand in for beef if you want something lighter. Any color bell pepper works so use what you have. For the topping you can use homemade cornbread batter instead of mix and Monterey Jack or Colby cheese also taste great as a topping.
Serving Suggestions
Serve with a simple green salad or steamed vegetables to balance out the richness. For a weeknight twist try topping each serving with a dollop of sour cream or a dash of hot sauce. This casserole is also delicious with a crunchy pickle or coleslaw on the side for a sweet tangy contrast.
