Layers of tender spaghetti, rich ground beef marinara, creamy cottage cheese, and plenty of melted mozzarella make this baked spaghetti recipe a satisfying alternative to a standard bowl of pasta. The casserole is assembled in layers, so every serving gets a combination of savory meat sauce, creamy cheese, and spaghetti held together just enough to slice and serve.
It is particularly useful when you need an easy family dinner recipe that can feed a group without requiring much attention once it goes into the oven. Baking it covered first keeps the pasta moist, while the final uncovered bake gives the mozzarella those appetizing golden spots. Serve it with a crisp salad, roasted vegetables, or garlic bread for a complete dinner.
Why This Baked Spaghetti Works
A good baked spaghetti casserole needs to stay saucy without turning loose or watery. This version handles that balance in several ways.
Cooking the spaghetti two minutes less than the package directions prevents it from becoming overly soft while it spends another 45 minutes in the oven. Eggs and melted butter coat the noodles, helping the finished casserole hold its shape. Cottage cheese adds moisture and creaminess between the pasta layers without requiring a complicated cheese filling.
Then there is the mozzarella. Using it both in the center and across the top produces stretchy cheese throughout the casserole and a bubbly, golden finish.
The result lands somewhere between classic spaghetti with meat sauce and a layered pasta bake, making it a practical choice when you want familiar flavors in a more substantial form.
If you prefer making the entire meal on the stovetop, this one-pot spaghetti recipe is another convenient approach.
Ingredients for Baked Spaghetti
You only need a short list of familiar ingredients for this cheesy baked spaghetti.
Spaghetti: One pound fills a standard 9×13-inch casserole dish. Cook it slightly under al dente because it will continue cooking in the oven.
Ground beef: A pound of ground beef gives the marinara a hearty, savory base. If your beef releases significant grease, drain the excess before adding the sauce.
Yellow onion: Chopped onion cooks alongside the ground beef, adding sweetness and savory depth.
Marinara sauce: Four cups provide enough sauce to keep the casserole moist. Use a marinara whose flavor you already enjoy because it is one of the dominant flavors in the dish.
Eggs: Two eggs bind the buttered spaghetti slightly so that the baked casserole is easier to portion.
Butter: Melted unsalted butter coats the pasta and adds richness.
Cottage cheese: The creamy cottage cheese creates soft, tangy layers between the pasta and meat sauce.
Mozzarella: Four cups may sound generous, but it is divided between two layers. It creates the signature cheesy center and golden top.
Kosher salt: A small amount seasons the noodle mixture. Remember that marinara and mozzarella also contribute salt.
How to Make Baked Spaghetti
1. Prepare the pasta
Preheat the oven to 350°F and lightly coat a 9×13-inch baking dish with vegetable oil spray.
Bring a large pot of water to a boil and cook the spaghetti for two minutes less than the package recommends. The noodles should remain slightly firm in the center. Drain them well.
Undercooking at this stage is important. Fully cooked spaghetti can become too soft after another 45 minutes in a hot, saucy casserole.
2. Make the ground beef marinara
While the pasta cooks, put the ground beef and chopped yellow onion in a large skillet over medium-high heat. Cook for about 5–6 minutes, breaking the beef into small crumbles, until the meat is thoroughly cooked and the onion has softened.
Drain excess fat if necessary, then stir in the marinara sauce until evenly combined.
For food safety, ground beef should reach an internal temperature of 160°F, as explained in the USDA guidance for safely preparing ground beef.
3. Coat the spaghetti
Combine the drained spaghetti with the kosher salt, beaten eggs, and melted butter. Toss thoroughly so the egg and butter are evenly distributed instead of concentrated in one area.
4. Layer the casserole
Spread half of the spaghetti across the bottom of the prepared baking dish. Add 1 cup of cottage cheese, followed by half of the meat sauce and 2 cups of shredded mozzarella.
Repeat the layers with the remaining spaghetti, cottage cheese, meat sauce, and mozzarella.
Spreading each ingredient close to the edges makes it easier to get all the components in every serving.
5. Bake until bubbly and golden
Cover the casserole with foil and bake at 350°F for 30 minutes.
Remove the foil and continue baking for approximately 15 minutes. The sauce should be hot and bubbling, while the mozzarella should be completely melted with golden spots across the surface.
Allowing the baked spaghetti to stand briefly before serving can make portions easier to cut and lift from the dish.
Tips for the Best Cheesy Baked Spaghetti
The biggest risk with a spaghetti casserole recipe is overcooked pasta. Do not skip the two-minute reduction in the initial pasta cooking time. The noodles absorb additional moisture from the marinara as they bake.
Drain watery or greasy liquid from the cooked beef before adding the marinara. Too much liquid can make the bottom of the casserole loose.
Shredding mozzarella from a block can give you especially smooth melting, although pre-shredded cheese is convenient and will work.
Make sure the foil covers the dish during the first 30 minutes. That traps moisture while the casserole heats through. Removing it for the last 15 minutes is what lets the mozzarella brown instead of simply steaming.
If the top has not developed as much color as you want after 15 minutes uncovered, give it another few minutes while watching closely.
Easy Baked Spaghetti Variations
Ricotta can replace the cottage cheese in equal amounts if you prefer a denser, smoother cheese layer. The texture and flavor will be somewhat richer.
For a different meat option, substitute ground turkey for the beef and cook it thoroughly before adding the sauce. You can also add sautéed mushrooms, bell peppers, or spinach, but cook vegetables with a high water content first so they do not release excess moisture into the casserole.
A small amount of grated Parmesan can be scattered over the mozzarella for a sharper, saltier finish.
For a more luxurious pasta dinner on another night, try this creamy lobster spaghetti Alfredo.
What to Serve with Baked Spaghetti
Because ground beef baked spaghetti is already substantial, simple side dishes work especially well. A green salad with a bright vinaigrette provides freshness against the rich cheese and meat sauce. Roasted broccoli, green beans, or zucchini also make good vegetable sides.
For a classic comfort-food meal, add warm garlic bread or crusty Italian bread for scooping up any marinara left on the plate.
Make-Ahead, Storage, and Reheating
To make the casserole ahead, assemble the layers in the baking dish, cover tightly, and refrigerate until you are ready to bake. Because a refrigerated casserole starts colder than one assembled with warm ingredients, it may require additional oven time. Make sure the center becomes thoroughly hot before serving.
Refrigerate cooked leftovers promptly in a covered container. The USDA’s leftovers and food-safety guidance recommends using most cooked leftovers within 3–4 days and reheating leftovers to 165°F.
Individual portions can be reheated in the microwave until hot throughout. For a larger amount, cover the casserole and reheat it in the oven so the spaghetti does not dry out. A spoonful of additional marinara can help restore moisture.
Baked spaghetti also freezes well. Divide completely cooled leftovers into meal-size portions and use freezer-safe airtight containers. Thaw overnight in the refrigerator before reheating for the most even results.
Frequently Asked Questions
Why do you put eggs in baked spaghetti?
The eggs lightly bind the cooked noodles. They help the casserole hold together when portions are cut without turning it into a firm egg-based dish. Mixing the eggs evenly through the spaghetti is important for a consistent texture.
Can I use ricotta instead of cottage cheese?
Yes. Replace the 2 cups of cottage cheese with 2 cups of ricotta. Cottage cheese produces a softer, slightly lighter layer, while ricotta creates a thicker and smoother cheese filling.
Should spaghetti be fully cooked before baking?
No. For this recipe, cook the spaghetti two minutes less than the package directions. Since it continues cooking in the oven with the sauce, slightly undercooked pasta is less likely to become mushy.
Why is my baked spaghetti watery?
Excess grease from ground beef, watery marinara, or vegetables added without cooking them first can introduce too much liquid. Drain excess fat from the meat and use a reasonably thick marinara. Also drain the cooked spaghetti thoroughly before assembling the casserole.
Can I make baked spaghetti without ground beef?
Yes. You can leave out the beef for a simpler cheese-and-marinara version or substitute an appropriate ground meat or plant-based alternative. Cook any substitute as needed before layering the casserole.
