Step‑by‑Step Instructions for Easy Sloppy Joe Casserole
Step 1: Cook the Beef
In a large skillet, brown 1½ pounds of ground beef over medium heat for about 7–10 minutes until fully cooked, breaking it apart with a wooden spoon. Ensure it’s browned and crumbly, then drain any excess fat to keep your Sloppy Joe casserole tasting its best.
Step 2: Add Vegetables
Next, stir in 1 finely chopped onion and 1 diced green bell pepper to the skillet. Sauté for approximately 5 minutes until the vegetables soften and become translucent, creating a savory base that enhances the overall flavor of the casserole.
Step 3: Mix Sauce
Now, add Worcestershire sauce, brown sugar, yellow mustard, ketchup, water, salt, and pepper to the meat and vegetable mix. Stir well to combine, then let the mixture simmer over low heat for 5 minutes until it thickens slightly, allowing the flavors of your Sloppy Joe filling to meld beautifully.
Step 4: Prepare Cornbread Batter
While the beef mixture simmers, in a separate mixing bowl, combine 1 Jiffy corn muffin mix, ⅓ cup milk, 2 tablespoons of vegetable oil, and 1 egg. Mix until just combined; don’t overmix, as you want your cornbread topping to stay light and fluffy for the casserole.
Step 5: Assemble the Casserole
In a greased 9×9-inch baking dish, spread the savory beef mixture evenly across the bottom. Once the filling is laid out, pour the cornbread batter over the top, ensuring it covers the filling nicely to create a delicious topping for your Easy Sloppy Joe Casserole.
Step 6: Bake
Preheat your oven to 350°F and place the assembled casserole inside. Bake for 25 to 35 minutes, or until the cornbread topping is golden brown and a toothpick inserted in the center comes out clean, indicating a perfectly baked casserole.
Step 7: Cool and Serve
Allow the casserole to rest for about 5 minutes once it’s out of the oven. This resting time helps it set a bit, making it easier to cut into squares. Serve warm, and enjoy the delightful blend of flavors in every comforting bite of your Easy Sloppy Joe Casserole!

Expert Tips for Sloppy Joe Casserole

Well-Browned Beef: Make sure to brown the beef well to develop rich flavors. Don’t rush this step, as it enhances the overall taste of your Sloppy Joe casserole.
-
Taste Test Before Baking: Always adjust seasoning before baking; flavors meld as it cooks, so make sure it’s just right before it goes in the oven.
