Why This Recipe Works

A blend of cheddar and mozzarella gives you both sharp flavor and stretchy melt. For another cozy cheese-forward bake, try our crock pot mac and cheese.

How to Make Cheesy Beef Casserole
1. Preheat and prep the dish
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Brown the beef
Cook the ground beef in a large skillet over medium heat until browned. Drain excess fat, then add onion and garlic and cook until softened.
3. Simmer the sauce
Stir in the tomato sauce, diced tomatoes, Italian seasoning, salt, and pepper. Simmer for 10 minutes until the flavors come together.
4. Combine with pasta
Stir the cooked pasta into the beef mixture until evenly coated.
5. Assemble and bake
Transfer the mixture to the prepared baking dish. Top with cheddar and mozzarella, then bake for 20 minutes until bubbly and golden.
6. Rest and serve
Let the casserole rest for 5 minutes, then garnish with parsley if desired and serve.

Frequently Asked Questions
Can I make this casserole ahead of time?
Yes. Assemble the casserole, cover, and refrigerate for up to 24 hours before baking. Add a few extra minutes to the bake time.
Can I freeze cheesy beef casserole?
Yes. Bake, cool completely, then freeze in a sealed container for up to 2 months. Thaw overnight and reheat covered in the oven.
What pasta works best?
Penne, rotini, and rigatoni all work well because they hold the sauce in every bite.
Can I use lean ground beef?
Yes. Lean ground beef works fine, but drain any excess liquid after browning.
Why is my casserole dry?
The sauce may have reduced too much or the pasta absorbed too much liquid. Add a splash of broth before baking if needed.
Can I make it spicier?
Yes. Add red pepper flakes, hot sauce, or pepper jack cheese for heat.
Can I double the recipe?
Yes. Use a larger baking dish and increase the bake time by 5 to 10 minutes as needed.
