This easy baked spaghetti recipe combines spaghetti, a flavorful sauce with ground beef, Parmesan cheese, and is topped with melty mozzarella for the perfect comforting casserole. The spaghetti is held together with eggs and cheese, making it easy to slice and serve. It is an amazing family dinner that can be assembled ahead of time or frozen for later.
As a lover of cooking and food, I treasure having my kids in the kitchen with me. I love teaching them simple cooking skills that I know they will carry with them as they grow. And they learn how to feel confident in the kitchen as I pass down this tradition of sharing love through food.
My Baked Spaghetti recipe is a great recipe to make with kids. It has moving parts and timing, so it is perfect for teaching those skills, while being a relatively uncomplicated recipe.
We had friends over this weekend and I was looking for a simple meal to fix. This baked spaghetti was just the ticket. Simple to make and everyone loved it.
Key Ingredients for Baked Spaghetti
- Spaghetti: Follow the instructions for boiling on the box, but cook it for 2 minutes less than the box suggests as the spaghetti will continue cooking in the oven
- Ground beef: I use 80/20 ground beef because the fat in it is used to sauté the onion and garlic. Once it has browned, drain off any excess grease. This can be replaced with Italian ground pork or ground turkey. If you use ground turkey note that you will need to add olive oil.
- Marinara sauce: This is the key ingredient to keeping the casserole from drying out. Either pick a brand that you love, or make my homemade marinara recipe. Please note that you will need to increase the recipe as it makes 28 ounces as written.
- Eggs and Parmesan cheese: These two ingredients are tossed with the spaghetti and work together to hold the casserole together and make it sliceable.
- Mozzarella: As always, I recommend shredding your cheese from the block for the best melting.
How to Make Baked Spaghetti
- Cook the spaghetti and ground beef. Bring a pot of water to a boil and cook your spaghetti noodles. You can find all of my tips for cooking pasta here: How to Cook Pasta. While they are cooking, cook your ground beef with onion and garlic. Break it up as it cooks until you no longer see any pink.
- Make the sauce. Drain the grease from the ground beef and stir in the marinara sauce and seasonings and allow to simmer.
- Make the spaghetti filling. Drain and rinse the cooked noodles and stir in Parmesan cheese and eggs.
- Put it all together. Layer the ingredients by starting with a little meat sauce, then adding the spaghetti mixture. Add the rest of the sauce and then top with shredded mozzarella.
- Bake uncovered for 25 to 30 minutes or until the cheese is bubbly and beginning to brown.
Why Add Eggs to Baked Spaghetti?
- Eggs help bind the noodles and cheese together so the baked casserole holds its shape when served.
- The eggs are optional, but without them you will have more of a saucy spaghetti bake and less of a cut-and-slice casserole.
- Rinsing the spaghetti before combining it with the eggs cools it a little and keeps the eggs from cooking in the heat of the noodles before the casserole is put together.
Storing and Reheating Leftovers
Leftovers can be stored in an airtight container in the refrigerator for up to three to four days. To reheat, cover and microwave the portion you plan to eat at half power until warmed through. You can also cover and bake just the portion you want to eat. Bake at 350 degrees Fahrenheit for 30 minutes.
Making Easy Baked Spaghetti Ahead
This is a great recipe to make on a Sunday afternoon, and then wrap and put in the refrigerator until you get home from work Monday evening. Put the dish together as the recipe calls for up to the point of putting it in the oven. Cover tightly with aluminum foil and put in the refrigerator for up to 24 hours. When ready to bake, put it in the preheated oven (straight from the refrigerator) uncovered for 30 to 35 minutes or until the casserole reaches an internal temperature of 165 degrees Fahrenheit.
If you would like to make ahead and freeze, it can be stored, tightly wrapped for up to three months in your freezer. Thaw in the refrigerator for 24 to 48 hours before baking.
Pro Tip: Make a Double Batch!
Double all of the ingredients and make it in two casserole dishes. Make one to eat right away, and freeze the second dish. It’s double the dinners without double the work.
Tips and Tricks
- Grate your own cheese. The melty cheese is one of the highlights of this recipe. A block of cheese that you grate yourself will melt a lot better than pre-shredded cheese.
- Make it vegetarian. Swap the meat that you brown at the beginning for vegetables. Good options are carrots, celery, zucchini, and bell peppers. Sauté them in two tablespoons of olive oil before moving on to Step 4.
- Swap the ground beef for ground turkey. Brown the ground turkey in two tablespoons of olive oil.
- Make your own marinara sauce: I love to make my Easy Homemade Marinara Sauce for this recipe. It is also delicious with meatballs.
- Leave out the eggs: If you are cooking for someone who can’t have eggs, you can leave them out of this recipe.
What to Serve with Baked Spaghetti

Can I freeze this for later?
Yes! There is a note about this in the post: If you would like to make ahead and freeze, it can be stored, tightly wrapped for up to three months in your freezer. Thaw in the refrigerator the overnight before baking.
