What’s in this Baked Spaghetti Recipe?

Cheesy and easy are two of my favorite words when it comes to food, and I love anything that I can make in a pinch for dinner during a chaotic week. This is exactly the recipe I need during this busy season of life!

Spaghetti: I like to use spaghetti for this casserole, but you can use any kind of pasta you love!
Ground Chuck: A bit fattier and tastier than ground beef.
Olive Oil + Butter: Add richness and help the beef cook without burning.
Onion + Garlic: Add an earthy and sweet flavor.
Marinara Sauce: Use your favorite brand or make your own!
Fresh Basil: Adds a pop of color and classic Italian flavor.
Cheese: Mozzarella and Parmesan are classic choices.
Salt + Pepper: Enhance the flavor of this dish.

Pro Tip: Cook the noodles to al dente for best results. If the noodles are super soft before baking, they’ll become pretty mushy and lack texture.

Variations on Spaghetti Casserole

You can swap out the ground chuck for regular ground beef, ground turkey, chicken, pork, or Italian sausage. Or make it vegetarian by skipping the meat altogether.

You can sneak some veggies into the sauce as well for extra nutrition– the kids won’t even notice!

This Baked Spaghetti Recipe is a lifesaver when it comes to quickly preparing a homemade dinner. Sure, it doesn’t get much simpler than classic spaghetti (always a delicious choice!), but add extra cheese and bake it until toasty perfection and you’ve got a weeknight dinner winner.

Becky’s tips

Spaghetti: Cook the noodles to al dente for best results. If the noodles are super soft before baking, they’ll become pretty mushy and lack texture.
Baking Pan: Use a 9×13 inch baking pan, or a similar equivalent (anything around 3 quarts is great).
Vegetarian: For a vegetarian baked spaghetti, simply omit the meat from the sauce.

Storage:Store baked spaghetti tightly covered with aluminum foil in the refrigerator for up to 4 days or in the freezer for up to 4 months.

What’s the point of baking spaghetti?

By baking this casserole, you get a crispy crust on top, adding a fun textural contrast!

Is baked spaghetti and lasagna the same?

Nope! Lasagna uses lasagna noodles and has a ricotta layer included.

Do you have to cook pasta before baking?

Yes. Cook the spaghetti to al dente, following the package instructions. Combine this cooked spaghetti with the sauce before baking.

Can I use a different kind of meat?

Definitely. Instead of ground beef, try ground chicken, turkey, or Italian sausage.

Do I cover baked spaghetti while it bakes?

I don’t recommend it – if covered while in the oven, the noodles will steam instead of truly bake, so you’ll end up with a pretty soggy baked spaghetti casserole.

How long is cooked spaghetti good for?

Cooked spaghetti will stay fresh for about 4 days when stored properly in the refrigerator.

What’s the best way to freeze baked spaghetti?

Prepare it ahead of time (through step #8), place it in a freezer-safe dish with a tight fitting lid, and freeze for 2-3 months. To bake, let it thaw in the refrigerator, then place it in the oven as instructed to fully bake through.
