Cheesy Beef & Tomato Casserole is the kind of comforting family dinner that combines simple ingredients with big, satisfying flavor. Savory ground beef is cooked with onions, garlic, tomatoes, and Italian-style seasonings, then layered with tender pasta and plenty of melted cheese for a bubbling, golden casserole that feels perfect for busy weeknights.
The rich tomato sauce keeps the casserole moist and flavorful, while the beef adds heartiness and the cheese brings everything together. Every serving has a delicious mix of meaty sauce, tender pasta, and gooey mozzarella with a lightly browned cheesy top.
This is also a practical make-ahead meal. You can assemble the casserole earlier in the day, refrigerate it, and bake it when dinner time arrives. Leftovers reheat beautifully, making it an excellent option for meal prep or feeding a hungry family.
Why You’ll Love This Cheesy Beef & Tomato Casserole
One of the best things about this recipe is how easy it is to customize. You can use whatever short pasta you have on hand, adjust the amount of cheese, add vegetables, or make the tomato sauce spicier depending on your family’s preferences.
The casserole also uses affordable everyday ingredients such as ground beef, canned tomatoes, pasta, and cheese. Despite its simplicity, it comes out of the oven looking and tasting like a hearty baked pasta dish you might order at a casual Italian restaurant.
It is filling enough to serve on its own, but adding garlic bread and a simple salad turns it into a complete dinner.

- 1 can (28 ounces) crushed tomatoes
- 1 can (14.5 ounces) diced tomatoes, drained
- 1 teaspoon Worcestershire sauce
- 1½ teaspoons Italian seasoning
- 1 teaspoon dried oregano
- ½ teaspoon smoked paprika
- ½ teaspoon onion powder
- ½ teaspoon salt
- ½ teaspoon black pepper
- ¼ teaspoon red pepper flakes, optional
- 1 teaspoon sugar, optional, if the tomatoes taste acidic
For the Casserole
- 12 ounces penne, rigatoni, rotini, or elbow pasta

How to Make Cheesy Beef & Tomato Casserole
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish with cooking spray or a thin layer of olive oil.
Set it aside while you prepare the filling.
2. Cook the Pasta
Bring a large pot of salted water to a boil.
Add the pasta and cook it approximately 2 minutes less than the package instructions recommend.
The pasta should be slightly firmer than al dente because it will continue cooking in the oven.
Drain thoroughly and set aside.
Avoid overcooking the pasta at this stage, or it may become too soft once the casserole is baked.
3. Brown the Ground Beef
Heat the olive oil in a large skillet over medium-high heat.
Add the ground beef and break it apart with a wooden spoon or spatula.
Cook for approximately 5–7 minutes, stirring occasionally, until the beef is browned and no pink remains.
If there is a large amount of excess grease in the skillet, carefully drain most of it while leaving a small amount behind for flavor.
4. Add the Onion and Garlic
Add the diced onion to the browned beef.
Cook for 3–4 minutes until softened.
Stir in the minced garlic and cook for approximately 30 seconds, just until fragrant.
Avoid cooking the garlic for too long because burnt garlic can make the sauce bitter.
5. Build the Tomato Sauce
Add the tomato paste and stir it into the beef mixture.
Cook for about 1 minute. Briefly cooking the tomato paste helps deepen its flavor.
Pour in the crushed tomatoes and diced tomatoes.
Add Worcestershire sauce, Italian seasoning, oregano, smoked paprika, onion powder, salt, black pepper, and red pepper flakes if using.
Stir everything together.
Bring the mixture to a gentle simmer.
6. Simmer the Beef Sauce
Reduce the heat to medium-low and simmer the sauce uncovered for approximately 10–15 minutes.
Stir occasionally.
The sauce should thicken slightly while still remaining loose enough to coat the pasta.
Taste the sauce before assembling the casserole. If the tomatoes are particularly acidic, stir in about 1 teaspoon sugar.
Adjust the salt and pepper as needed.
7. Combine the Pasta and Sauce
Add the cooked pasta directly to the skillet with the beef and tomato mixture.
Stir until every piece of pasta is evenly coated.
For an extra creamy casserole, stir in the sour cream or ricotta cheese.
Add approximately ½ cup mozzarella and ½ cup cheddar to the mixture and stir gently.
The cheese will begin melting into the warm sauce.
8. Assemble the Casserole
Transfer half of the beef and pasta mixture into the prepared baking dish.
Sprinkle with a small amount of mozzarella, cheddar, and Parmesan.
Add the remaining beef mixture.
Spread it evenly across the baking dish.
Top generously with the remaining mozzarella, cheddar, and Parmesan.
Make sure the cheese reaches close to the edges so every serving gets plenty of melted topping.
9. Bake Until Golden and Bubbling
Cover loosely with aluminum foil.
Bake at 375°F for 20 minutes.
Remove the foil and continue baking for another 10–15 minutes, or until the sauce is bubbling around the edges and the cheese is completely melted.
For a more deeply golden cheese topping, broil the casserole for approximately 1–2 minutes at the end.
Watch it carefully because cheese can brown very quickly under the broiler.
10. Rest Before Serving
Remove the casserole from the oven and allow it to rest for approximately 5–10 minutes.
This short resting period helps the sauce settle and makes the casserole easier to portion.
Finish with chopped parsley or fresh basil.
Serve while hot and cheesy.
What to Serve With Cheesy Beef & Tomato Casserole
Garlic bread is one of the best sides for this casserole. The crispy bread is perfect for soaking up any tomato sauce left on the plate.
A simple green salad also provides a fresh contrast to the rich beef and cheese.
Other delicious serving options include:
- Garlic knots
- Caesar salad
- Roasted broccoli
- Steamed green beans
- Roasted asparagus
- Sautéed zucchini
- Italian chopped salad
- Roasted Brussels sprouts
For a casual family dinner, serve generous portions of the casserole with garlic bread and a fresh salad.
Tips for the Best Cheesy Beef & Tomato Casserole
Undercook the pasta slightly. Pasta continues cooking in the oven, so boiling it until completely soft beforehand can produce a mushy casserole.
Brown the beef properly. Allow the beef to develop some caramelized edges instead of constantly stirring it.
Do not make the sauce too dry. The pasta absorbs additional moisture while baking.
Use freshly shredded cheese. Freshly grated mozzarella and cheddar generally melt more smoothly than bagged pre-shredded cheese.
Let the tomato paste cook. Cooking tomato paste for a minute before adding liquid gives the sauce a deeper flavor.
Rest before serving. Cutting into the casserole immediately can cause it to fall apart.
Easy Recipe Variations & Substitutions
Creamy Beef & Tomato Casserole
Add 4 ounces softened cream cheese or ½ cup heavy cream to the tomato sauce before combining it with the pasta.
This creates a richer, creamier filling.
Spicy Beef Casserole
Add ½ teaspoon crushed red pepper flakes or diced jalapeños.
You can also use pepper Jack cheese in place of some of the cheddar.
Beef and Mushroom Casserole
Cook 8 ounces sliced mushrooms with the onions before adding the garlic.
The mushrooms add extra savory flavor and make the casserole even heartier.
Beef and Spinach Casserole
Stir 2 cups fresh baby spinach into the hot tomato sauce.
Allow it to wilt before adding the pasta.
Vegetable Beef Casserole
Add diced bell peppers, zucchini, mushrooms, or spinach to increase the vegetable content.
Ground Turkey Version
Ground turkey can replace the beef.
Because turkey is leaner, adding an extra tablespoon of olive oil can help keep the filling moist.
Make-Ahead Instructions
This casserole is excellent for preparing ahead.
Complete the recipe through the assembly stage but do not bake it.
Cover the baking dish tightly with foil and refrigerate for up to 24 hours.
When ready to bake, remove it from the refrigerator while the oven preheats.
Bake covered for approximately 25–30 minutes, then uncover and continue baking until the cheese is golden and the casserole is hot throughout.
A refrigerated casserole may require an additional 5–10 minutes compared with one baked immediately.
Storage and Reheating
Allow leftover casserole to cool completely.
Transfer it to an airtight container or cover the baking dish tightly.
Refrigerate for up to 3–4 days.
For individual portions, microwave until hot.
For larger portions, cover the casserole with foil and reheat at 350°F for approximately 15–20 minutes.
Adding a tablespoon or two of tomato sauce before reheating can help prevent the pasta from drying out.
Can You Freeze Cheesy Beef & Tomato Casserole?
Yes.
Assemble the casserole in a freezer-safe dish and allow all ingredients to cool completely.
Wrap tightly with plastic wrap followed by aluminum foil.
Freeze for up to 2–3 months.
For best results, thaw overnight in the refrigerator before baking.
You can also freeze individual cooked portions for easy future lunches or dinners.
