I can’t get enough of casseroles these days. I love that you can make them ahead of time, they’re easy to freeze, and they usually involve cheese.

This baked spaghetti has the best meat sauce, and it comes together so quickly and easily. You can use tons of different kinds of pastas in here too. (Rotini would be great.)

It’s also a WIN because I always have all of the necessary ingredients in the house.

If you’ve never tried adding a dab of cream cheese to your marinara sauce, oh my gosh, it’s time to try it. I can pretty much guarantee that you’ll love it. Just a dab’ll do ya! (That’s what my art teacher use to say about glue.) Anyway…

Storing Baked Spaghetti

-Baked spaghetti should be refrigerated and is best if used within three days.

Freezing Baked Spaghetti

Baked spaghetti can be frozen after it’s been baked. It’s best to wrap portion sizes in foil and place them in a labeled freezer bag.

To reheat from a frozen state, leave it in the foil and bake at 350 degrees for 25 minutes or more, depending on the serving size.
