Baked Spaghetti is a great freezer meal. A veritable Italian casserole of coziness that you can enjoy now, then save the rest for later or share the goodness with friends and family.
When my son was little, spaghetti pie was his most requested meal. As he got older and his appetite grew, I adapted that recipe to make baked spaghetti. A baked spaghetti casserole is just what you need when you have a house full of hungry teenagers.
One of the things I love about bakes spaghetti is how well it freezes. Assemble this dish in square foil pans and freeze for a ready-made dinner on a busy weeknight. Oh, how I love a good freezer meal recipe like this.
I have to warn you that this recipe makes A LOT of pasta. If you have a large family or enjoy leftovers, I say go for it. Otherwise, freeze half for later use. I sometimes freeze all of it for later use.

What To Serve With Baked Spaghetti
The great thing about this dish is that it is quick and easy to re-heat. So you will want to find a side dish that is equally quick and easy (there’s no sense in whipping up the spaghetti in minutes, only to have to wait for the side dish!).
- Garlic Bread: It’s the classic side for a classic meal. Easy to make from scratch or bought refrigerated.
- Caesar Salad: Another go-to. These salads can be as simple or as complex as you want them to be. Plus, you can buy Caesar Salad kits at the store, so you never need to spend more than a couple of minutes putting one together.
- Roasted Vegetables: Broccoli, carrots, or zucchini can be easily prepared (just chop them up then put them in the oven with olive oil, salt, and pepper) and provide a nutritious side.

FAQs
The sour cream and egg mixture seeps down into the spaghetti while baking, and binds the noodles for a creamy and delicious casserole.
1/2 cup grated Parmesan cheese is the remaining cheese that you sprinkle on top.
While I haven’t baked it from completely frozen, I think it will be all right. You’ll need to adjust the cooking time and keep it in a little longer.
Since the aluminum containers are not very deep, I was only able to fit two layers of lasagna in the freezer containers. I typically do 3 layers in a 9×13 pan, so I was able to do an additional square container with the additional ingredients. Depending on how large you like your servings, you can expect to get 3-4 servings from each freezer meal. I hope that helps.
I never do since the noodles and sauce are already cooked. Just be sure that your pasta is cooked no more than al dente. With baked pastas I to to undercook the noodles a bit. I hope you enjoy!
It’s one 16 ounce box.
