Remember church potlucks or even funeral gatherings where casseroles abounded? There's a reason for that, of course. Casseroles are typically easy to make, travel well, and most can be frozen to save for later.

This chicken spaghetti casserole covers all of those characteristics: it's super easy to put together, you can freeze it unbaked, and it's not too saucy so it travels well.

How to Make Chicken Spaghetti Casserole

  • Place all ingredients except one cup of the grated cheese in a large mixing bowl and stir gently until well mixed. 
  • Spoon into a lightly greased 9x13 baking dish or 3 or 4 smaller dishes. Cover with foil.
  • NOTE: Make-ahead tip: Store in refrigerator for up to two days or freezer for up to three months.
  • If baking immediately, place covered casserole in preheated 350 oven and bake 30 minutes.
  • Remove foil and bake another 15 minutes or until cheese is fully melted and casserole is bubbly around the edges.

You can also make this a couple of days in advance if you're having a party and just stick it in the refrigerator until you're ready to bake. It's a versatile recipe to which you can add different vegetables if you like or keep it simple like I do.

And if you're cooking for two then just put the casserole in small baking dishes and make several meals out of it.
