Ingredients

  • Chopped cooked turkey
  • Packaged stuffing mix
  • Thawed frozen peas
  • Shredded cheddar cheese
  • Cream of mushroom soup
  • Packaged mashed potato mix
  • Packaged gravy mix

Recipe Steps

Preheat oven to 375°F and then spray a 13x9x2” baking dish with cooking spray.

Prepare the stuffing, mashed potatoes, and gravy following the instructions on the packages. Combine the prepared gravy and mushroom soup in a medium-sized mixing bowl.

Spread the stuffing in the bottom of the prepared baking dish. Layer the turkey on top, and then sprinkle the peas over the top of the stuffing.

Pour the gravy mixture over the top of the turkey and peas. Spread the potatoes on top, and then sprinkle the cheddar cheese over the casserole.

Cover the baking dish with foil and bake the turkey casserole for 20 to 30 minutes. Remove the foil and bake it for ten minutes or until the cheese is melted and the dish hot. Let it stand for five minutes at room temperature before serving.

Recipe Tips and Variations

You can make one big casserole or divide up the leftovers to make small Thanksgiving casserole dishes to enjoy in the days after the big holiday. They will keep well for a few days in the refrigerator.

I love that it’s easy to switch up the ingredients in this Thanksgiving leftover casserole. So, feel free to use what you have on hand to make it. Here are some ideas you might like to try:

  • Meat: You can use leftover whole roasted turkey, roast turkey breast, or roasted chicken. Or, pick up a rotisserie chicken at the store to use in this recipe. Sometimes we make it with cooked ground turkey during other times of the year. It works great, too.
  • Mashed Potatoes: Any kind of mashed potatoes will work, like homemade or prepared mashed potatoes that you can get at the store.
  • Gravy: We have a great homemade gravy recipe that we love to use in this dish.
  • Veggies: We love peas, but a lot of other vegetables will go well with this casserole. Roasted brussels sprouts, cooked green beans, corn… there are a lot of options.
  • Stuffing: We always make extra stuffing for holiday dinners, so we have leftovers for this Thanksgiving casserole.
  • Cheese: Any kind of cheddar cheese is great, or try Parmesan cheese, Gruyere, or Provolone.

If you’re planning your big dinner and looking for Thanksgiving casserole recipes to try, you should add this one to your list. It’s so easy to adjust based on what you’ll have leftover. I hope you give it a try this year – Enjoy!
