Ingredients needed

To make this freezer spaghetti squash meal, you’ll need:

• Spaghetti squash: The base of the casserole.
• Pasta sauce: You will need two jars of your favorite pasta sauce.
• Pesto: You’ll need one small jar of pesto sauce. About 6 ounces.
• Meatballs: I recommend using pre-cooked frozen meatballs for this recipe. About 12 ounces. You can also make your own.
• Parmesan cheese: To top the casserole with.

How to make this recipe

Begin by preheating your oven to 400 degrees and then line a baking sheet with aluminum foil or spray with non-stick spray. Wash your spaghetti squash and cut it in half going lengthwise.

Bake your squash for 45 minutes. Note that if you have a larger spaghetti squash you may need to cook it longer.

Let it cool and then scoop the seeds and stringy bits out. Use a fork to shred the spaghetti squash.

Combine the squash noodles and pesto together. Mix well and then add the pasta sauce in. Add the mixture to a well greased 9 x 13 inch casserole dish.

Garnish generously with shredded Parmesan cheese. You can add the meatballs on top to bake or bake them separately. Bake at 350 degrees for 30 minutes or until the cheese is melted. You can broil for 30 seconds to get the cheese extra melted.

To freeze, let it cool, put in a freezer safe plastic storage bag, remove any excess air, and then freeze for a later date.

Can you freeze spaghetti squash noodles?

If you’re wondering if you can freeze spaghetti squash noodles you absolutely can! This meal is one of the best freezer meals I have made and it freezes great. You can also freeze smaller portions for quick and easy lunches.

How to make this a freezer meal

To freeze, let it cool, put in a freezer safe plastic storage bag. Lay it flat, label, and freeze for a later date. It will be good in the freezer for up to three months.

How to reheat from froze

This baked spaghetti squash and meatballs recipe also defrosts really well. The spaghetti squash remains firm even when defrosted which is awesome. I love to make a big batch and then freeze half for later. I would recommend letting this recipe defrost a few hours (or overnight) before reheating it. You can easily reheat it in small portions at a time in your microwave or on your stove-top.

What do I do if my spaghetti squash is still firm after baking?

Some larger spaghetti squash or more firm squash may need a longer baking time. If your squash is still firm after 45 minutes, you can speed up the process by microwaving it for two to three minutes or you can bake it for an additional 15 minutes.

Shortcuts for this recipe

If you’re short on time, there are a few shortcuts for this recipe. As mentioned above, you can use store bought pre-cooked meatballs (about 15 ounces). Many grocery stores now carry prepped spaghetti squash cubes in a bag which will also reduce the prep work for this recipe.
