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

Years ago, while looking for Turkey Leftover Recipes, I tried this Turkey Casserole on a whim. It was so well-loved by the family that it’s now a post-Thanksgiving tradition!

Why You Must Make

  • It’s a terrific way to use up the last of the Thanksgiving turkey.
  • Made with a creamy sauce, it’s delicious!
  • If my picky family approves, then yours will, too.

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. The recipe called for chicken (but I knew I could sub turkey), noodles, mushrooms, and cream, all of which I had on hand. I add peas for a pop of color and to incorporate a vegetable into the dish.

This homemade turkey casserole was meant to be. Making this casserole has become a once-a-year, post-Thanksgiving 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.

Ingredient Notes

  • Kitchen Staples – Butter, Salt, Freshly Ground Black Pepper
  • Turkey Meat (or Chicken) – 2-3 cups, cubed or shredded.
  • Small Pasta – 8 ounces. I like farfalle (bow ties) or orecchiette (small shells that resemble ears).
  • Mushrooms – I use button mushrooms, sliced in half. They will be sauteed in butter before adding to the pasta.
  • Peas – I use defrosted frozen peas.
  • White Wine – I keep cooking sherry or vermouth in my fridge to use in cooking. You can also use any white wine you happen to have open.
  • Flour – I prefer Wondra Flour which is a granular, quick-mixing flour that’s less likely to form lumps when making sauces and gravy. If you’re a gravy pro, all-purpose flour will also work well.
  • Chicken Broth – I use the Pacific brand. If you use another brand, you may need to reduce the added salt as some broths are very salty.
  • Whipping Cream – Heated. Warm gently in the microwave.
  • Grated Parmesan Cheese – Look for Parmesano Reggiano; never use the green can of cheese that’s on the store shelf. Sprinkle over the casserole before baking.

How to Make Turkey Tetrazzini

  1. Cut leftover turkey into bite-sized chunks or shred it into bite-sized pieces.
  2. Cook pasta in salted water, and drain.
  3. Saute mushrooms and taste for seasoning.
  4. Make the sauce with chicken broth.
  5. Add warm cream to the sauce.
  6. Toss the pasta, turkey, mushrooms, and peas with the cream sauce.
  7. 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 is a wonderful pantry alternative.

Transformed from Thanksgiving leftovers, I hope you’ll give this homemade turkey tetrazzini recipe a try. Don’t forget to try it with chicken for the rest of the year!

Recipe Tips

  • For those gravy impaired like me, Wondra“quick mixing” flour blends easily without forming lumps. (affiliate link)
  • If your family loves turkey tetrazzini, you can use chicken when you don’t have leftover turkey.
  • This recipe calls for warm whipping cream. I like to gently warm the cream in a 2 cup Pyrex liquid measuring cup, watching it carefully so it doesn’t boil over and make a mess.

What to Serve with Tetrazzini

Tetrazzini has protein, carbs, and a smattering of vegetables, but a couple of side dishes are a nice addition to the menu. Garlic Bread is wonderful, plus a tossed green salad. Roasted vegetables like Parmesan Green Beans or Balsamic Carrots are delicious additions, too.

Frequently Asked Questions

What is Tetrazzini?

The original dish is a rich entree made with spaghetti, strips of chicken, and a sauce of sherry, Parmesan, and cream. It is topped with bread crumbs or Parmesan and baked until hot and bubbly.
It was said to be named after Luisa Tetrazzini, an opera singer. It is not an Italian dish, but instead American. Turkey is often substituted for chicken.

What Is the Difference Between Tetrazzini and Alfredo?

Both tetrazzini and Alfredo have a sauce made with cream and Parmesan. Alfredo also has butter and is served tossed with wide, flat fettuccine pasta. Tetrazzini is traditionally made with spaghetti and is baked.

What Else Can Be Added to Tetrazzini?

Though chicken is most classic, and turkey is an obvious substitution, shrimp is also a tasty addition. Peas are not classic but a nice addition, or even the combination of frozen peas and carrots.
For an extra cheesy casserole, add some shredded mozzarella or white cheddar towards the end of the baking time. Or you can add it to the turkey mixture before placing it in the baking dish.

Can You Make Tetrazzini Ahead of Time?

Yes, it can be prepped the day before and placed in a casserole dish. Cover tightly and store overnight in the refrigerator. The baking time will need to be extended when cooking a cold casserole.

How to Store Leftover Tetrazzini?

Keep it covered tightly in the refrigerator for 3-4 days. Leftovers can be frozen for up to 3 months if stored airtight. Just defrost overnight in the refrigerator before reheating.
