Easy Baked Spaghetti Casserole
This baked spaghetti casserole recipe is one of our new family favorites. It’s a bit like lasagna but so much easier to make! And sometimes I think the leftovers are an even bigger hit, as everyone always wants them for lunch.
Baked spaghetti is made with the obvious elements – spaghetti noodles and pasta sauce – plus lots of cheese. Parmesan is mixed in with the noodles for added flavor, while mozzarella is sprinkled on top and baked until bubbling. No wonder the family loves it!

What You’ll Need
This spaghetti casserole uses spaghetti and a jar of pasta sauce, plus a few ingredients to add more flavor. (And cheese, of course.) See the recipe card below for measurements.
- Spaghetti – Cook to al dente according to the package instructions.
- Onion & garlic – These aromatics add flavor to the pasta sauce.
- Seasonings – The only spices needed for this baked pasta recipe are Italian seasoning, salt, and black pepper.
- Pasta sauce – Any jarred pasta sauce you prefer will work.
- Diced tomatoes – Enhances the tomato flavor in the pasta sauce.
- Cheese – Parmesan cheese is added to the pasta while mozzarella is sprinkled on top. Freshly shredded is always best.
- Parsley – For garnish.
Can I Use Homemade Spaghetti Sauce?
Yes, you can use your preferred homemade pasta sauce, like marinara sauce or spaghetti meat sauce. Use your judgment on whether you still need to add the aromatics and spices called for in this recipe, as your homemade sauce likely already has them.
How to Make Baked Spaghetti
This spaghetti casserole makes a quick and easy weeknight dinner that the entire family will love.
- Cook the beef. Brown the ground beef with the onion, garlic, and seasonings until no longer pink. Drain any excess grease.
- Simmer the sauce. Add the pasta sauce and diced tomatoes to the meat. Simmer for 10 minutes.
- Assemble the casserole. Add the pasta to a greased casserole dish then add the sauce, parmesan, and parsley. Mix until the spaghetti is fully coated.
- Bake. Sprinkle the spaghetti casserole with the mozzarella cheese. Bake for 15 to 20 minutes, until the cheese has melted.
- Enjoy. Cut into large squares and serve.
Recipe Tips & Variations
Here are a few tips for making this baked spaghetti for the first time, as well as a few variations.
- Don’t overcook the pasta. Cook the pasta just to al dente. It will continue to cook in the oven, so overcooking it can lead to a mushy casserole.
- Spice it up. Add ½ teaspoon of crushed red pepper to the sauce for a kick.
- Rest before slicing. Let the casserole sit for about 5 minutes after you remove it from the oven, so the cheese solidifies a bit and it’s easier to slice and serve.
- Make it vegetarian. For a vegetarian dish, just omit the ground beef from the sauce. Mushrooms would make a great replacement to saute with the garlic and onions.
- Do you cover baked spaghetti? No, you shouldn’t cover this dish when baking it. Covering it with foil will create steam which can make the spaghetti a bit soft. Plus, you really want that cheese to bubble and brown just a bit!
Can Baked Spaghetti Be Prepared In Advance?
Yup! One of the things I love most about this spaghetti bake is that it can be assembled in advance. Once everything is combined in the casserole dish, cover it with foil, and refrigerate for up to a day.
Note that you may have to add 5 to 10 minutes to the cooking time, since it will be cold when you put it in the oven.
What to Serve with Spaghetti Casserole
We like to serve this baked spaghetti recipe with the same things we’d serve regular spaghetti – some type of bread and an easy side salad.
We love using this garlic butter to turn any bread we have on hand into garlic bread and garlic knots are fun too. But you can never go wrong with Olive Garden breadsticks either! (And a slice of crusty French bread or any other bread always works in a pinch too.)
How to Store & Reheat Leftovers
- Fridge. Store leftover baked spaghetti in the refrigerator for up to 3 days in an airtight container.
- Reheat. You can heat the entire pan in the oven, covered in foil, or reheat individual portions in the microwave.
Can I Freeze Baked Spaghetti?
Yes! This dish freezes superbly. You can freeze it before or after baking. Just allow it to cool then cover tightly with foil and freeze for up to 3 months. Thaw overnight in the fridge then bake in the oven until heated through. (If it was already baked, cover it with foil if necessary to avoid burning the cheese.)
