Turkey Tetrazzini

From homemade turkey soup to turkey salad, you can do a lot with leftover Thanksgiving turkey or roast turkey breast. But my favorite way to make leftovers really last is by making homemade turkey tetrazzini recipe.

Turkey tetrazzini has been a post-Thanksgiving dinner tradition in my family since before I was born. My dad learned how to make it from my grandmother, who made hers with canned cream of mushroom soup, chopped pimentos, and gobs of shredded cheddar cheese. 

While her version was good, I prefer this homemade version better. And If big forkfuls of sliced mushrooms aren’t your thing, dice them into tiny pieces. You’ll hardly notice they’re there at all.

How to Make Turkey Tetrazzini

1. Prep Ingredients: Preheat the oven to 350 degrees Fahrenheit and spray a large casserole dish with nonstick cooking spray. Shred the turkey and cheese (or cheeses!), and chop the veggies. At the same time, bring a large pot of salted water to a boil.

2. Soften the vegetables: Cook the onions, mushrooms, and garlic until softened in a large heavy-bottomed Dutch oven or skillet set over medium heat. Stir in the white wine and bring to a simmer. Reduce by half.

What Can I Substitute For White Wine?

This is one of the most frequently asked questions I get from readers. In the case of this turkey tetrazzini recipe, swap the dry white wine for water, turkey stock or broth, or homemade chicken stock or broth.

3. Prepare the roux: To simplify things, we’re leaving the onions and mushrooms in the pan – including them as part of the roux.

  • What is a Roux? Roux is flour and fat (butter, lard, vegetable oil) cooked together and used to thicken sauces, soups, and stews.

Melt the remaining butter with the onions and mushrooms, then sprinkle everything with flour. Mix it all together until combined (it will form a thick paste).

4. Make the sauce: Slowly whisk in the chicken broth, chicken stock, or turkey broth, followed by the heavy cream (or half-and-half) — season with salt, black pepper, and fresh thyme. Bring to a simmer before reducing the heat to low.

Tip: Add 4-8 ounces of softened spreadable cream cheese for a super creamy, luscious sauce.

5. Combine: Add the turkey, frozen peas, and half of the cheese to the sauce. Let things simmer and cook for a few minutes before seasoning with additional salt or pepper (and maybe some red pepper flakes) to taste.

6. Assemble: Mix the spaghetti noodles with the sauce before transferring everything to the prepared casserole dish. Top with the remaining shredded cheddar cheese.

7. Bake and serve: Transfer to the oven and tent with foil. Bake for 30 minutes covered, remove the foil, and continue to bake for 15 minutes. Remove from the oven and serve garnished with freshly cracked black pepper, if desired.

Recipe Tip

  • Sprinkle the top with buttery breadcrumbs, panko breadcrumbs, and cheese for a golden brown, crispy, crunchy top!
  • Swap the spaghetti noodles for any other pasta shape or noodle, like linguini or penne.
  • Reserve 1-2 cups of the boiling salted pasta water before draining your noodles. Use it to thin the sauce if it becomes too thick.

Storing and Freezing

  • Can Turkey Tetrazzini be made ahead? Yes, you can prepare it ahead and refrigerate it before baking. Just add a few minutes to the baking time if it’s going straight from the fridge to the oven.
  • How long does Turkey Tetrazzini last in the fridge? Allow leftovers to cool to room temperature before storing them in an airtight container in the refrigerator for up to 4 days.
  • Can you freeze Turkey Tetrazzini? Yes. Allow leftovers to cool to room temperature before transferring them to an airtight container or freezer bag. Freeze for up to 3 months.
  • How do you reheat Turkey Tetrazzini? Thaw frozen leftovers in the refrigerator overnight before reheating. To reheat in the oven, cover with foil and bake at a low temperature (around 350°F) until reheated. Microwaving is also an option, especially for single servings.

Ingredients 

  • 5 cups cooked turkey, shredded
  • 1 pound (16 ounces) dry spaghetti noodles
  • 1 tablespoon olive oil
  • 6 tablespoon butter, divided
  • 1 medium yellow onion, minced
  • 8 ounces crimini mushrooms, sliced
  • 5 cloves garlic, minced
  • ¾ cup dry white wine
  • 3 tablespoon all-purpose flour
  • cups low-sodium chicken stock, or homemade turkey stock
  • ½ cup heavy cream
  • 1 teaspoon salt, plus more to taste
  • 2 teaspoon fresh thyme, minced
  • ½ teaspoon freshly ground black pepper
  • 1 cup frozen peas
  • 2 cups white cheddar cheese, shredded
  • Fresh lemon juice, for serving

Instructions 

  • Preheat oven – Preheat oven to 350 degrees F. and spray a large casserole dish with nonstick cooking spray. Set aside.
  • Shred the turkey – gather approximately 5 cups of cooked turkey and shred into small, bite-sized pieces (see notes).
  • Boil the spaghetti – Bring a large pot of salted water to a boil over high heat. Add the noodles and cook until just under al dente. Drain, rinse, and set aside.
  • Sauté the vegetables – Heat the olive oil and one tablespoon of butter in a large, heavy-bottomed Dutch oven over medium-high heat. Add the onion and cook for 2-3 minutes or until starting to soften. Add the mushrooms and cook for 3-4 minutes or until tender. Stir in the minced garlic and cook for 1 minute. Add the white wine and bring to a simmer. Cook until the liquid is reduced by half.
  • Prepare the roux – Over medium heat, melt the remaining butter with the onions and mushrooms. Sprinkle with flour, whisking continuously to combine the flour with the melted butter, forming a thick paste covering the onions and mushrooms (this is your roux).
  • Make the sauce – Whisking continuously to prevent clumping, slowly add the chicken broth. Once the chicken or turkey stock has been incorporated, add in the heavy cream – season with salt, black pepper, and fresh thyme. Bring to a low simmer, then reduce heat to low.
  • Return the turkey – Add the turkey, frozen peas, and half of the cheese to the sauce and simmer for 2-3 minutes – season with additional salt and pepper to taste.
  • Assemble – Mix in the spaghetti noodles and mix before transferring everything to your prepared casserole baking dish. Sprinkle with additional thyme, if desired, and top with the remaining shredded cheddar cheese.
  • Bake – Transfer to the oven and tent with foil. Bake for 30 minutes covered, then remove the foil tent and continue to bake for an additional 15 minutes.
  • Serve – Allow the baking dish to rest for 5 minutes before serving. Enjoy!

Notes

Substitutions and alternatives:
  • Although this is a turkey tetrazzini recipe, boneless chicken will also work when a leftover Thanksgiving turkey isn’t available. Rotisserie chicken or leftover chicken breasts are a great option when you’re in a hurry. You may also poach chicken breasts which take approximately 30 minutes.
  • Swap heavy cream for half-and-half
  • Trade spaghetti noodles for egg noodles. Be extra careful to cook your noodles at least 2 minutes less than the advised package directions as egg noodles are more likely to fall apart when overcooked.
  • Add different flavors with different types of cheeses – parmesan cheese, mozzarella cheese, shredded Italian blend, etc.

    Thank you for this recipe. It was very good. I wasn’t exactly sure what a large casserole dish size was but my 9 x 13 pyrex worked well.
    It did take me a bit longer to make it than it did you. The only thing I might do next time is have less spaghetti. It might even work with 10-12 oz spaghetti instead of the full 16 oz. It might have been a little saucier then, which I like…
    Thanks again!

      Thank you so much for the feedback. 🙂

      I am glad you enjoyed it, and yes, a 9×13 Pyrex is exactly the size I use for a large casserole dish. It is really helpful to know you would prefer it a bit saucier with less spaghetti, and using 10 to 12 ounces next time is a great idea and an easy way to adjust it to your taste.
