If You Want to Make This Another Time of Year …

If you want to make this tetrazzini recipe other times of the year, feel free to use leftover chicken. Or to make it super fast and easy for busy weeknights, pick up a rotisserie chicken and use it because I know you may not always have leftover holiday turkey laying around.

Here’s an overview of how the easy turkey tetrazzini is prepared:

Step 3: Melt the butter in a skillet, then sauté the onions and garlic.

Step 4: Add the celery, bell peppers, salt, pepper, and cook momentarily.

Recipe FAQs

Do I Have to Use Canned Condensed Soup?

I make this super easy turkey tetrazzini with cream of mushroom soup. I know condensed soup and “cream of …” type soups can sometimes get a bad rap. However, condensed soup has been used for generations and in this recipe in particular which came from my grandma, I have never not used it.

I use cream of chicken soup AND sometimes even some cream of mushroom soup in place of spaghetti sauce. My results are always creamy and delicious. I’m a big fan of the motto, “if it’s not broke, don’t break it.”

This recipe works amazingly well with condensed soup and I don’t recommend trying to replace it. If it’s not your jam, that’s fine. I am sure you can find another recipe for turkey tetrazzini without it.

Why Is There Spaghetti Sauce in the Recipe?

This is a family recipe that’s been around for quite some time and wouldn’t have it any other way even though I realize spaghetti sauce isn’t a traditional turkey tetrazzini ingredient.

However, spaghetti sauce adds a tangy, flavorful note that really enhances this savory meal and gives it another flavor dimension.

And before you ask, no, this leftover turkey tetrazzini does not taste like spaghetti with red sauce! However, if you are opposed to using the spaghetti sauce, omit it. In place of it, I recommend using cream of mushroom soup.

Can I Use This Recipe to Make Chicken Tetrazzini?

Yes, you certainly can! If you’re craving a good chicken tetrazzini dinner, you can use this exact recipe – just swap the Thanksgiving turkey for cooked chicken. You can always keep thing simple by using an already cooked rotisserie chicken from the grocery store, or make my favorite Poached Chicken which is a great swap here, too.

What to Serve with Turkey Tetrazzini 

You know all of those leftover side dishes you have in your refrigerator? They will all plate perfectly alongside a heaping serving of homemade Turkey Tetrazzini!

Some of my favorite Thanksgiving sides that I make every single year include:

They all reheat like a dream in the microwave, so they’ll be ready to go when that fast turkey tetrazzini comes out of the oven.

Or if you’re just ready for some French bread or Texas toast, go for it. Also if you are craving some fresh and healthy after a big holiday meal, my Waldorf Salad is fast, easy, and fresh. A House Salad would go nicely with this easy turkey tetrazzini as well, too.

How to Store Leftovers

Curious about how to store your leftovers of this leftover-based dish?

After the turkey tetrazzini has cooled to room temperature, pop it into an airtight food storage container and place it in the fridge where it’ll keep for up to 5 days.

It’ll also keep airtight in the freezer for up to 3 months. Reheat it gently in the microwave.

Tips For The Best Turkey Tetrazzini

Pasta: Whether you use spaghetti noodles or another type of pasta, it’s important not to overcook them. Follow the package instructions and cook them just until al dente. They’ll cook more in the oven, and you don’t want them to become mushy, so it’s important not to overdo it when boiling them.

Additionally, you can use another type of long-strand noodle such as linguine. 

Pasta Water: I always reserve about 1/2 a cup or more of the water that the spaghetti is cooked in. The starchy water makes the cream sauce a little thinner if it’s a little too thick. You can add more or less of the pasta water based on how it’s looking to you. Better to reserve it and not need it, than vice versa.

Spaghetti or Marinara Sauce: As I mentioned, you can omit it and instead use cream of mushroom soup if you’d like. One 10.5-ounce can should do the trick.

Cream Sauce: Does it seem like there’s too much sauce? Don’t worry! As the casserole bakes, the noodles will soak up a good amount of the sauce. Additionally, any time pasta or noodles sit in the fridge, they always continue to soak up a bit more of the sauce so don’t worry. Better to be saucy than dry!

The Dairy: I like to use heavy cream but half-and-half should be fine. Make sure to use full-fat, brick-style cream cheese and nothing labeled “lite” because it contains too much water and it’ll create a too-thin sauce. 

I use shredded Colby Jack in my easy turkey or chicken tetrazzini. However, feel free to use shedded mozzarella, shredded Parmesan, or another favorite cheese. And you can always add more than the 1 cup the recipe calls for. I never say no to more cheese!

Ingredients  

  • 1 pound spaghetti noodles, or linguine or another long-strand pasta, plus 1/2 cup reserved pasta water
  • 6 tablespoons unsalted butter, divided
  • ¼ cup white or yellow onion, diced small
  • 3 to 4 cloves garlic, finely minced
  • ½ medium green bell pepper, seeded and diced small (yellow bell pepper may be substituted)
  • ¼ cup celery, diced small
  • ¾ teaspoon salt, or to taste
  • ¾ teaspoon freshly ground black pepper, or to taste
  • 1 ½ cups sliced mushrooms, white, button, baby portobello, etc.
  • two 10.5-ounce cans cream of chicken soup*
  • 1 ½ cups spaghetti sauce OR one 10.5-ounce can cream of mushroom soup**
  • 1 cup heavy cream, half-and-half may be substituted
  • 4 ounces brick-style full-fat cream cheese, do not use lite products
  • 2 cups leftover cooked turkey, shredded or diced small (leftover chicken or rotisserie chicken may be substituted)
  • 1 cup shredded Colby Jack cheese, plus more optionally to taste (shredded mozzarella or shredded Parmesan may be substituted)
  • 1 cup Italian-style breadcrumbs
  • 2 teaspoons fresh parsley, finely minced; optional for garnishing

Instructions 

  • Cook the spaghetti according to package directions until al dente. Reserve 1/2 cup pasta water. Drain noodles and set them aside in a large bowl.
  • Preheat the oven to 350F and spray a 3 to 4-quart casserole dish or 9x13-inch baking pan with cooking spray; set aside.
  • To a large skillet, add 3 tablespoons butter, the onions, garlic, and saute over medium-high heat for about 4 minutes, or until the onion is beginning to soften. Stir nearly constantly so you don't burn the garlic.
  • Add the bell peppers, celery, salt, pepper, and saute for about 2 minutes, stirring frequently.
  • Add the cream of chicken soup, spaghetti sauce OR cream of mushroom soup, heavy cream, cream cheese, and stir continuously until the cream cheese melts and you have a smooth cream sauce.
  • Add the turkey (or chicken) and stir to incorporate.
  • If desired to thin out the sauce a bit if it seems a bit thick, add the pasta water, a couple tablespoons at a time, stirring after each addition, until sauce reaches desired consistency.
  • Either add the spaghetti to the saute pan if it's big enough pan, or pour the sauce over the spaghetti if you have it in a bowl, and toss very well to combine.
  • Transfer the mixture to the prepared baking dish.
  • Evenly sprinkle with the cheese; set aside.
  • To a small saucepan, add the remaining 3 tablespoons butter, and heat over medium-high heat to melt; stirring constantly.
  • Add the breadcrumbs to the butter and stir to toss and coat evenly.
  • Evenly sprinkle the breadcrumbs over the cheese layer over the coated spaghetti in the casserole dish.
  • Bake for about 30 minutes, or until the top is bubbling and is as lightly golden browned as desired. Tip - Based on what kind of cheese you used, your exact casserole dish and oven, etc. baking time will vary so keep an eye on it starting at 25 minutes. Based on your variables, if it takes 40 minutes to bake, so be it and I would not be surprised. Bake until done.
  • Optionally garnish with parsley and serve. Leftover turkey tetrazzini will keep airtight in the fridge for up to 5 days or in the freezer for up to 3 months. Reheat leftovers gently in the microwave before serving.

Notes

*Cream of chicken soup (and potentially cream of mushroom soup, see below) are the only way I know how to make this recipe and have never substituted them.
*No, this easy turkey tetrazzini does not taste like spaghetti with red sauce but use cream of mushroom soup instead if you're concerned.
