Making Baked Spaghetti Ahead of Time

-Baked Spaghetti can be prepared and assembled up to two days before baking.

-It can also be assembled and frozen before it’s baked. Before serving, let it defrost in the refrigerator overnight, then proceed with baking per the recipe.

Storing Baked Spaghetti

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

Freezing Baked Spaghetti

Baked spaghetti makes a great freezer food 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.
