Homemade Turkey Tetrazzini is the perfect recipe for Thanksgiving leftovers with chunks of turkey, peas, mushrooms, and a rich cream sauce. So easy and delicious that my family expects it every year after the holiday!!

Years ago, I tried this Turkey Leftover Recipe on a whim and it was so well-loved by the family that it’s now a post-Thanksgiving tradition!

I did not grow up eating tetrazzini, in fact, I don’t even think I knew what it was when I was leafing through my Joy of Cooking the day after Thanksgiving years ago. But the recipe called for chicken (but I knew I could sub turkey), noodles, mushrooms, and cream, all of which I had on hand.

This homemade turkey casserole was meant to be. Making this casserole has become a once a year event.

The next Thanksgiving, I was asked to make this turkey leftover recipe again. Apparently, the kiddos, who were not usually fans of casserole type dishes, approved. So our annual tradition is to eat days and days of leftover turkey, mashed potatoes, and stuffing. When there is only a bit of meat clinging to the bones, I cross my fingers and hope to pick off at least three cups from the carcass so I can whip up this tetrazzini recipe.

How to Make Turkey Tetrazzini

  • Cut leftover turkey into bite-sized chunks or shred into bite-sized pieces.
  • Cook pasta in salted water, drain.
  • Saute mushrooms and taste for seasoning.
  • Make the sauce with chicken broth.
  • Add warm cream to the sauce.
  • Toss the pasta, turkey, mushrooms, peas with the cream sauce.
  • Pour into a casserole dish, sprinkle with Parmesan, if desired, and bake until lightly browned and heated through.

Turkey Leftover Recipes

Today, I’m sharing one of our favorite recipes utilizing Thanksgiving leftovers, and much as I’d like to cook up something new and different, Turkey Tetrazzini is always on our menu the weekend after the holiday. And I don’t mind one bit.

There is always some cream in the refrigerator, leftover from whipping up a bowlful to dollop on our pumpkin pie. Grated Parmesan, frozen peas, chicken broth, and pasta are also staples. I just make sure to have fresh mushrooms on hand, though a jar or can of mushrooms would be a wonderful pantry alternative. Transformed from Thanksgiving leftovers, I hope you’ll give this homemade turkey casserole a try.  Don’t forget to try it with chicken for the rest of the year!

Tip of the Day: For those gravy impaired like me, Wondra“quick mixing” flour blends easily without forming lumps. (affiliate link)

A delicious pasta, turkey, mushroom and cream sauce casserole for your turkey leftovers.


  • 3 cups shredded or cubed cooked turkey meat
  • 1/2 pound pasta, I use orcchiette or farfalle, cooked in well-salted water and drained
  • 1/2 pound (or more!) mushrooms, trimmed and cut in half or sliced
  • 3 tablespoons sherry (or white wine)
  • 3 tablespoons butter
  • 3 tablespoons flour (Wondra preferred as it doesn't lump)
  • 2 cups of chicken broth
  • 1 cup heavy cream, warmed ( I heat in the microwave in a Pyrex measuring cup)
  • 1 cup frozen peas
  • Salt and pepper to taste
  • Grated Parmesan cheese


  1. Preheat oven to 375°.
  2. Sauté mushrooms in butter till lightly browned. Add salt and pepper to taste. Deglaze the pan by adding sherry and cooking until most evaporates. Remove mushrooms and add flour to the pan. Cook for just a minute, then add the chicken broth, whisking to avoid lumps. Cook till mixture thickens slightly. Add cream and stir to combine. Remove from heat. Add the turkey and peas, check for seasoning, and add more salt and pepper as needed.
  3. Place pasta into a 9 x 13-inch baking dish (I use a smaller dish for a deeper casserole). Push pasta to the sides of the dish to create a bowl in the middle of the dish. Scoop out chicken, mushrooms, and peas and arrange in the center of the dish. Pour sauce over top of the dish. Sprinkle with Parmesan. (Alternatively, toss the pasta with the sauce, chicken, mushrooms, and peas. Pour into the baking dish and sprinkle with Parmesan).
  4. Bake till lightly browned and heated through, about 15-20 minutes.
