Ingredients for Sloppy Joe Casserole
- 1 lb ground beef
- 1/2 cup chopped onion
- 1/2 cup chopped green bell pepper
- 2 cloves garlic, minced
- 1 cup ketchup
- 1 tbsp tomato paste
- 1 tbsp Worcestershire sauce
- 1 tsp yellow mustard
- 1 tsp brown sugar
- 1/2 tsp smoked paprika
- Salt and pepper to taste
- 2 cups elbow macaroni, cooked and drained
- 2 cups shredded mozzarella cheese
- 1/2 cup shredded cheddar cheese
- Fresh parsley for garnish (optional)

Step 1: Prepare the Beef Mixture
In a large skillet over medium heat, add the ground beef. Cook until it’s browned and no longer pink, breaking it apart with a spatula as it cooks. Drain any excess fat. Add the chopped onion, green bell pepper, and garlic to the skillet. Sauté everything together for about 3–4 minutes, or until the vegetables are soft and fragrant.
Step 2: Make the Sloppy Joe Sauce
Reduce the heat slightly, then stir in the ketchup, tomato paste, Worcestershire sauce, yellow mustard, brown sugar, smoked paprika, and a pinch of salt and pepper. Mix well until everything is combined and the sauce thickens slightly—let it simmer for about 5 minutes to allow the flavors to deepen.
Step 3: Combine with Pasta
While the beef mixture simmers, cook the elbow macaroni in salted boiling water until just al dente. Drain and set aside. Add the cooked pasta to the skillet with the Sloppy Joe mixture and stir to coat every noodle in the rich, savory sauce.
Step 4: Assemble the Casserole
Preheat your oven to 375°F (190°C). In a greased 9×13-inch baking dish, pour in the beef and pasta mixture, spreading it out evenly. Top with the shredded mozzarella and cheddar cheeses, making sure the entire surface is generously covered.
Step 5: Bake and Serve
Bake the casserole uncovered for 15–20 minutes, or until the cheese is melted and bubbly. If you’d like a golden-brown cheesy top, broil it for the last 2–3 minutes—just keep an eye on it. Once done, garnish with freshly chopped parsley and let it cool slightly before serving.
Storage Instructions
Sloppy Joe Casserole is a fantastic make-ahead or leftover-friendly dish. Once cooled, transfer any leftovers into an airtight container. You can refrigerate it for up to 4 days. For longer storage, portion the casserole into freezer-safe containers or wrap tightly with foil and freeze for up to 2 months. To reheat, warm individual servings in the microwave or reheat the whole casserole in the oven at 350°F (175°C) until heated through. If frozen, allow it to thaw in the fridge overnight before reheating.
