How to Make a Thanksgiving Leftover Casserole

This layered Thanksgiving Leftover Casserole recipe takes about an hour to prep from start to finish. And the process to make it is almost too easy:

  • Spread your pre-made potatoes across a baking dish as a base.
  • Layer on your turkey, gravy, green beans, more turkey, and stuffing on top.
  • Finish by pouring some broth and gravy evenly over the entire dish, then bake it all for 35–40 minutes at 350°F.

You’ll want to remove the aluminum foil covering about halfway through baking so the top layer of stuffing gets all crispy, making every bite tender on the outside, chewy and delicious on the inside. And voilá! A hearty but healthy leftover turkey casserole blend of goodness to extend the holiday celebration.

The best part? You don’t have to worry that by extending your Thanksgiving feast, you’re also extending your waistline. One serving of this leftover turkey casserole only has 200 calories per serving and 7 grams of fat, and boasts 18 grams of protein.

We’re always thankful for a delicious meal we don’t have to compromise our diet goals for. And who knows? You might find you love this leftover turkey casserole so much, it becomes a mainstay for Thanksgivings to come. Happy feasting!
