I grew up thinking casseroles were something only grandmas made for church potlucks. Then I had kids and realized why every parent needs a good casserole in their back pocket—it’s all mixed together in one dish, and somehow that makes it way more appealing to picky eaters.
This ground beef noodle casserole is the one I make when I need dinner on the table fast and don’t want to hear any complaints. It’s got everything kids actually want to eat: pasta, beef, cheese, and a little marinara to hold it all together. The best part? You can prep it ahead and just pop it in the oven when you’re ready. No fancy techniques required, just basic cooking that gets the job done.

Why You’ll Love This Ground Beef Noodle Casserole
- Budget-friendly dinner – Ground beef and pasta are affordable staples that come together to feed your whole family without breaking the bank.
- Quick and easy – This casserole is ready in under an hour, making it perfect for busy weeknights when you need dinner on the table fast.
- Simple ingredients – You probably already have most of these pantry staples at home, so no special shopping trip required.
- Kid-approved comfort food – The combination of cheesy pasta and seasoned ground beef is a classic that even the pickiest eaters will happily devour.
What Kind of Ground Beef Should I Use?
For this casserole, you’ll want to pick up ground beef with a fat content that balances flavor and texture. I typically go with 85/15 ground beef (that’s 85% lean, 15% fat) because it gives you enough fat for good flavor without leaving your casserole swimming in grease. If you prefer a leaner option, 90/10 works too, though you might want to add a touch more olive oil to keep things moist. Whatever you choose, make sure to drain off any excess fat after browning the meat – this keeps your casserole from getting too oily and helps the marinara sauce shine through.

Options for Substitutions
This casserole is pretty forgiving when it comes to swapping ingredients:
- Penne: Any short pasta shape works great here – try rigatoni, ziti, rotini, or even elbow macaroni. They all hold the sauce well and bake nicely.
- Ground beef: Ground turkey, chicken, or pork are all solid substitutes. You can also use Italian sausage (remove the casings first) for extra flavor, or go meatless with crumbled firm tofu or plant-based ground meat.
- Marinara: Any tomato-based pasta sauce works fine. You can use plain tomato sauce and add Italian seasoning, or even diced tomatoes if you don’t mind a chunkier texture.
- Cheddar: Mozzarella is a natural swap for a more traditional Italian taste. You can also try Monterey Jack, Colby, or a Mexican cheese blend. For best results, shred your own cheese rather than using pre-shredded.
- Onion and garlic: If you’re short on fresh, use 1 teaspoon onion powder and 1/2 teaspoon garlic powder instead. Add them when browning the meat.
Watch Out for These Mistakes While Cooking
The biggest mistake people make with this casserole is overcooking the pasta during the initial boil, which leads to mushy noodles after baking – aim for about 2 minutes less than the package directions since the pasta will continue cooking in the oven.
Don’t skip draining the excess fat from the ground beef after browning, as too much grease will make your casserole oily and prevent the sauce from coating the noodles properly.
Another common error is adding the garlic at the same time as the beef and onions, which can cause it to burn and taste bitter – wait until the meat is fully cooked, then add the garlic for just 30 seconds before mixing in the marinara.
When broiling at the end, keep a close eye on the cheese since it can go from golden to burnt in seconds, and if your broiler runs hot, consider moving the rack down one level to avoid a charred top.

What to Serve With Ground Beef Noodle Casserole?
This hearty casserole is pretty filling on its own, so I like to keep the sides simple and fresh. A crisp green salad with Italian dressing is my go-to since it cuts through the richness of the cheese and beef. Garlic bread or buttery breadsticks are always a hit for soaking up any extra sauce on your plate. If you want to add some veggies, roasted broccoli or green beans work really well alongside this dish, and they’re easy to throw in the oven while the casserole bakes.
Storage Instructions
Store: This casserole is a great make-ahead meal that keeps well in the fridge. Once it’s cooled down, cover it tightly with foil or transfer to an airtight container, and it’ll stay fresh for up to 4 days. It’s one of those dishes that actually tastes even better the next day after all the flavors have had time to meld together.
Freeze: You can absolutely freeze this casserole for busy weeknights. Let it cool completely, then wrap it tightly in plastic wrap followed by aluminum foil, or divide into individual portions in freezer-safe containers. It’ll keep for up to 3 months in the freezer.
Reheat: To warm it up, bake covered at 350°F for about 20-25 minutes if refrigerated, or 45-50 minutes if frozen. You can also microwave individual portions for 2-3 minutes, stirring halfway through. If the cheese needs a little refresh, pop it under the broiler for a minute or two to get it bubbly again.

- Carbohydrates: 300-320 g
Ingredients
For the pasta:
- 1 lb penne (I always use Barilla for the best al dente texture)
For the beef mixture:
- 1 tbsp olive oil
- 1 lb ground beef
- 1 onion (finely diced into 1/4-inch pieces)
- 2 garlic cloves
- 1.5 cups marinara (I prefer Rao’s Homemade for its rich flavor)
- 1/4 teaspoon red pepper flakes
- salt
- pepper
For the topping:
- 2 cups cheddar (sharp cheddar gives the best flavor and melt)
Step 1: Prepare the Oven and Mise en Place
- 1 onion, finely diced
- 2 garlic cloves, minced
Preheat your oven to 400°F and lightly grease a 9×13 inch baking dish with oil or cooking spray.
While the oven heats, finely dice the onion into 1/4-inch pieces and mince the garlic cloves.
This prep work ensures everything is ready when you need it, so the cooking process flows smoothly without interruption.
Step 2: Start the Pasta and Brown the Beef
- 1 lb penne
- 1 tbsp olive oil
- 1 lb ground beef
- 1 onion, finely diced from Step 1
Bring a large pot of salted water to a boil and add the penne, cooking for 9 minutes (we’ll finish cooking it in the oven, so keep it slightly under al dente).
While the pasta cooks, heat the olive oil in a large skillet over medium-high heat and add the ground beef and diced onion.
Cook for about 8-10 minutes, breaking the beef into small pieces as it browns, until the onion is soft and the meat has lost its pink color.
I like to use a meat thermometer to ensure even browning—the beef should reach about 160°F internally.
Step 3: Build the Meat Sauce Base
- 2 garlic cloves, minced from Step 1
- 1.5 cups marinara
- 1/4 teaspoon red pepper flakes
- salt
- pepper
Add the minced garlic to the skillet and cook for about 1 minute until fragrant.
Stir in the marinara sauce and red pepper flakes, then drain any excess fat from the pan if needed.
Let the sauce simmer gently for 2-3 minutes to meld the flavors, then season with salt and pepper to taste.
This short simmer helps the spices infuse into the sauce for better flavor throughout the casserole.
Step 4: Drain Pasta and Assemble the Casserole
- penne from Step 2
- meat sauce from Step 3
Drain the pasta in a colander (don’t rinse it—the starch helps the dish come together).
Pour the cooked penne into the greased baking dish, then add the meat sauce from Step 3 and stir gently to combine, ensuring the noodles are evenly coated.
The combination of slightly undercooked pasta and the gentle bake in the oven will bring everything to perfect texture.
Step 5: Top with Cheese and Bake
- 2 cups sharp cheddar cheese
Spread the sharp cheddar cheese evenly over the top of the casserole.
Place the dish in the preheated 400°F oven and bake for 10 minutes until the cheese is melted and bubbly.
I prefer sharp cheddar because it has deeper flavor and melts beautifully without becoming oily like milder cheeses can.
Step 6: Broil and Finish
Turn the oven to broil and place the casserole 6 inches from the heat for about 2 minutes, watching closely, until the cheese has a light golden-brown color on top.
Remove from the oven and let it rest for 2-3 minutes before serving—this allows the cheese to set slightly and makes plating easier.
