Ingredients You’ll Need

1 pound ground beef (or ground turkey for a leaner option)
1 small onion, diced (yellow or white works best)
1 green bell pepper, diced (adds a nice crunch and sweetness)
2 cloves garlic, minced (fresh is best, but jarred works too)
1 can (15 oz) tomato sauce
½ cup ketchup (classic adds tang, but feel free to use a low-sugar version)
2 tablespoons brown sugar (adds signature Sloppy Joe sweetness)
1 tablespoon Worcestershire sauce (for deep, savory flavor)
1 tablespoon yellow mustard (brings that zingy balance to the sweetness)
Salt and black pepper, to taste
3 cups cooked pasta (elbow macaroni or penne both work well; short pasta holds sauce best)
2 cups shredded cheddar cheese, divided (mild or sharp depending on preference)
1 cup crushed crackers or French fried onions (optional, for topping) (adds a delightful crunch and texture contrast)

Step-by-Step Instructions

Preheat the oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish and set aside.
Cook the meat and veggies:
- In a large skillet over medium heat, cook the ground beef until browned and no longer pink.
- Drain any excess fat to avoid a greasy casserole.
- Add the diced onion, green bell pepper, and minced garlic. Sauté until vegetables are soft and fragrant, about 5 minutes. The onions should be translucent.
Make the Sloppy Joe sauce:
- Stir in tomato sauce, ketchup, brown sugar, Worcestershire sauce, mustard, salt, and pepper.
- Bring the mixture to a simmer. Let it cook uncovered for about 5 minutes, stirring occasionally, until it thickens slightly and the flavors meld.
Combine with pasta:
- In a large mixing bowl, combine the cooked pasta with the meat sauce.
- Stir in 1 cup of shredded cheddar cheese so it gets melty and coats the pasta well.
- Mix thoroughly to ensure even distribution of sauce and cheese.
Assemble the casserole:
- Pour the pasta and meat mixture into the prepared baking dish.
- Spread it out evenly with a spatula.
- Sprinkle the remaining 1 cup of cheddar cheese over the top.
- If using, add a generous layer of crushed crackers or French fried onions for extra crunch.
Bake:
- Place the casserole in the preheated oven.
- Bake uncovered for 20–30 minutes, or until the cheese is melted, bubbly, and golden brown.
Cool slightly before serving:
- Remove the dish from the oven and let it rest for 5–10 minutes.
- This helps the casserole set and makes it easier to slice and serve.

Serving and Storage Tips

Serve Sloppy Joe Casserole warm, straight from the oven. It pairs beautifully with a crisp green salad, steamed green beans, or even some roasted veggies. You could also serve it with garlic bread or cornbread to soak up every last bit of sauce. For a party or potluck, keep it in a warming tray or covered dish and let guests help themselves.

Storage:

Refrigerator: Store leftovers in an airtight container in the fridge for up to 4 days. The flavors continue to develop and it reheats beautifully.
Freezer: Freeze the unbaked or fully baked casserole in a freezer-safe container for up to 3 months. Wrap tightly with plastic wrap and foil to prevent freezer burn.
Reheating: To reheat from the fridge, microwave individual portions or reheat the entire dish in a 350°F oven until warmed through. Add a fresh sprinkle of cheese on top before reheating for extra melty goodness.

Helpful Notes

Meat substitutions: Try ground chicken, pork, or plant-based meat crumbles for a different flavor.
Cheese options: Monterey Jack, mozzarella, or a spicy pepper jack make fun alternatives.
Add-ins: Toss in diced mushrooms, corn kernels, black beans, or even a handful of baby spinach to boost the nutrition.
Make it spicy: Add chopped jalapeños or red pepper flakes for heat.
Gluten-free: Use your favorite gluten-free pasta and double-check that your sauces and toppings are certified gluten-free.
Dairy-free: Use plant-based cheese and skip the crunchy topping if needed.
More topping ideas: Crushed tortilla chips, seasoned breadcrumbs, or even a few dollops of sour cream after baking.

Frequently Asked Questions

Can I freeze this casserole?
Yes! You can assemble the casserole and freeze it before baking. Just cover it tightly with foil. When ready to enjoy, thaw in the fridge overnight and bake as directed. You can also freeze leftover cooked portions in individual containers.
What if I don’t have Worcestershire sauce?
You can substitute with soy sauce or a combination of soy sauce and a splash of vinegar for similar depth and tang.
Can I make this ahead of time?
Absolutely. Prepare the entire casserole a day in advance, cover, and refrigerate. When you're ready, uncover and bake until heated through and bubbly.
Is it spicy?
Not at all. The flavor is sweet and tangy, but you can customize it by adding a dash of hot sauce or red pepper flakes to the sauce.
What kind of pasta works best?
Short pastas like elbow macaroni, penne, rotini, or shells are ideal. They hold onto the sauce and cheese better than long noodles.
