Leftover turkey casserole is also great to place in the freezer to serve at a later date. It will extend your Thanksgiving holiday long into the winter and let you put those Thanksgiving turkey leftovers to good use, rather than forgetting they’re in the fridge and having to throw them away.

Ingredients

See recipe card below this post for ingredient quantities and full instructions.

  • Unsalted butter
  • Panko breadcrumbs – While regular breadcrumbs work too, panko gives the topping some extra crunch!
  • Parmesan
  • Dried oregano
  • Onion – Make sure to dice them nice and small.
  • Celery – Dice the celery the same size as the onions so they cook at the same time.
  • Garlic
  • Cream of chicken soup – Adds flavor and thickness to the creamy sauce.
  • Sour cream
  • Cheddar cheese
  • Leftover turkey – Shred or cube the turkey for the casserole.
  • Egg noodles – Cook the noodles according to the package instructions.
  • Frozen peas
  • Lemon zest – Adds a nice brightness to the casserole.
  • Parsley
  • Kosher salt & black pepper to taste

Variations

  • Not a fan of peas? Try frozen green beans instead.
  • Want to amp up the veggies even more? Sautéed mushrooms would be delicious too!
  • Have some crispy French fried onions leftover from your green bean casserole? You can use those for the topping instead of the panko mixture!
steps to make leftover turkey casserole

How To Make Leftover Turkey Casserole

  1. Prepare: Preheat the oven to 400ºF and lightly grease a 9×13 baking dish. Melt half of the butter in the microwave and set aside.
  2. Make The Topping: In a small bowl, combine the panko, half the parmesan, and melted butter. Mix everything together until the butter is fully combined and set to the side.
  3. Prepare The Casserole: In a Dutch oven, add the remaining butter, onion, and celery. Cook together over medium heat for about 4 minutes. Add in the garlic and continue to cook for about a minute. Add the soup and sour cream into the pot and continue to stir. Let the mixture come to a simmer. Add in the cheddar and parmesan cheese and stir to combine. Stir in the turkey, noodles, peas, lemon zest, and parsley. Season with salt and pepper as needed.
  4. Bake The Casserole: Pour the turkey mixture into the prepared baking dish and top with the buttered breadcrumbs. Bake until the crumbs on top of the casserole are golden brown, about 25 minutes. Let the casserole cool for about 10 minutes before serving.

Quick Tip

When cooking the noodles, you want them to be al dente, or a little less than fully cooked. Don’t worry, they’ll finish cooking in the casserole sauce while it bakes in the oven!
