What Exactly Is Turkey Tetrazzini? Tracing Its Delicious Roots

Despite its distinctly Italian-sounding name, Turkey Tetrazzini is a culinary creation firmly rooted in American tradition, a fact that often surprises many. If you were to ask an Italian about “Tetrazzini,” you’d likely be met with a puzzled expression. This iconic dish was, in fact, conceived in the early 20th century in San Francisco. Legend has it that a talented chef at the prestigious Palace Hotel crafted this pasta dish in honor of the renowned Italian opera singer, Luisa Tetrazzini, during her stay. Its immediate popularity transformed it into a beloved family staple, cherished across generations.

At its heart, Tetrazzini is a luscious casserole typically featuring diced poultry – commonly turkey or chicken – intertwined with pasta and earthy mushrooms, all lovingly coated in a rich, creamy, and often cheesy sauce. While linguine or spaghetti are the traditional pasta choices, the beauty of Tetrazzini lies in its adaptability. Feel free to substitute with other shapes like farfalle, penne, or even egg noodles, depending on your preference. A final flourish of grated cheese and fresh parsley often completes this delightful ensemble.

The Versatility and Benefits of This Delicious Casserole

Beyond its incredibly satisfying flavor profile, this creamy and cheesy turkey tetrazzini is remarkably versatile, making it a perfect meal for any occasion, especially for utilizing leftover holiday turkey. Its adaptable nature allows for endless customization, ensuring it caters to every palate and pantry:

Vegetable Customization: Not a fan of peas? Simply omit them. Adore mushrooms? Feel free to double the quantity for an even deeper umami flavor. The recipe welcomes other vegetables like bell peppers, broccoli florets, or spinach, adding both nutrients and color.
Protein Options: While turkey is the star here, cooked chicken (roasted, shredded, or rotisserie) makes an excellent substitute. You could even experiment with ham or a combination of meats.
Cheese Choices: Parmesan and cheddar create a classic combination, but don’t hesitate to explore other cheeses. Pecorino Romano offers a sharper, saltier kick, while Gruyère or Fontina would lend a nutty, melt-in-your-mouth quality. Even a smoky provolone could add an interesting twist.
Pasta Perfection: As mentioned, linguine or spaghetti are traditional, but short-cut pastas like penne, rotini, or even egg noodles can work beautifully, capturing the creamy sauce in every bite.

A non-negotiable aspect of nearly all my recipes is preparing them from scratch. The difference in flavor between homemade and store-bought ingredients is truly immense, and I find the taste of preservatives utterly off-putting. I assure you that despite its gourmet appeal, this turkey tetrazzini recipe is surprisingly straightforward and uncomplicated, proving that extraordinary flavor doesn’t require extraordinary effort.

Crafting the Perfect Tetrazzini: Essential Ingredients and Expert Tips

To achieve the ultimate cheesy turkey tetrazzini, understanding the role of each ingredient and incorporating a few expert tips can make all the difference. This recipe builds layers of flavor from the ground up, ensuring every spoonful is a delight.

Key Ingredients for a Standout Tetrazzini

The Turkey: This dish is a fantastic way to transform leftover roasted turkey from Thanksgiving or any family dinner. Its rich flavor forms the backbone of the casserole. If you don’t have leftovers, cooked and shredded chicken breast or thigh meat works equally well.
Aromatics: A robust base of chopped yellow onion, celery, and minced garlic provides a fragrant foundation. Sautéing these until tender sweetens the vegetables and releases their full aroma.
Mushrooms: Sliced crimini mushrooms add a deep, earthy, umami richness that is characteristic of classic tetrazzini. Sautéing them until slightly browned concentrates their flavor.
The Creamy Sauce:
- Butter and Flour (Roux): These form the roux, the thickening agent for our luxurious sauce. A proper roux ensures a smooth, lump-free consistency.
- Chicken Broth and Heavy Cream: These liquids create the creamy body of the sauce. Using good quality chicken broth will significantly enhance the overall flavor.
- Sour Cream: A touch of sour cream adds a subtle tang and an extra layer of richness, balancing the savory elements.
Seasonings: Italian seasoning, dried parsley flakes, thyme, paprika, onion powder, salt, and black pepper are carefully selected to provide a balanced and aromatic profile that complements the turkey and vegetables without overpowering them.
Colorful Vegetables: Chopped carrots, red pepper, frozen peas, and jarred chopped pimentos not only add nutritional value but also introduce delightful textures and a vibrant array of colors to the casserole.
Pasta: Linguine or spaghetti are traditional choices, offering long, comforting strands that beautifully coat in the creamy sauce. However, feel free to use your preferred pasta shape; the key is to slightly undercook it before baking.
Cheeses: A generous amount of finely shredded cheddar cheese melts into a gooey, savory blanket, while Parmesan cheese contributes its signature nutty, salty notes. This combination creates an irresistible cheesy layer.

The Irresistible Garlic Buttercrumb Topping

The topping is what truly elevates this tetrazzini from great to extraordinary. Panko breadcrumbs are tossed with melted butter, garlic powder, paprika, and a pinch of salt. Panko, with its larger, flakier texture, creates an incredibly crispy and light topping, far superior to regular breadcrumbs. This golden crust adds a vital textural contrast to the soft pasta and creamy sauce below, ensuring every bite is a delightful experience.

Ingredients

For the Tetrazzini

6 Tbsp. butter
1 medium yellow onion, chopped
4 stalks celery, chopped
2 large cloves garlic, minced
16 oz. sliced crimini mushrooms
4 Tbsp. cooking sherry
5 Tbsp. flour
2 cups chicken broth
2 cups heavy cream
1/2 cup sour cream
1/2 tsp. Italian seasoning
2 Tbsp. dried parsley flakes
1 Tbsp. thyme
1/4 tsp. paprika
1 tsp. onion powder
1 -1/2 tsp. salt
1 tsp. black pepper
2 medium carrots, peeled and chopped
1 red pepper, cored, seeds removed, chopped
1 cup frozen peas
1/4 cup (jarred) chopped pimentos, drained
3 – 4 cups chopped/shredded turkey
8 oz. linguini or spaghetti
2 cups finely shredded cheddar cheese
1/4 cup parmesan cheese

For the Topping

3/4 cup panko breadcrumbs
3 Tbsp. melted butter
1/2 tsp. garlic powder
1/4 tsp. paprika
1/4 tsp. salt
garnish: 1/4 cup minced Italian parsley

Instructions

In a large frying pan (skillet), melt the butter.
In a large pot, boil water to cook the pasta.
Saute onions until semi-soft, about 5 minutes.
Add celery and garlic to the pan. Continue to saute for 5 more minutes until fragrant.
Add sliced mushrooms and saute until they are slightly browned and have released their liquid.
Remove all the cooked vegetables from the pan, leaving any remaining liquid. Set the vegetables aside in a bowl.
Deglaze the pan by pouring in the cooking sherry. Scrape up any browned bits from the bottom of the pan and cook for one to two minutes until the sherry has reduced slightly.
Add the flour to the pan and mix well with the pan drippings and sherry to form a roux. It will be very lumpy. Cook for one minute, stirring constantly, to cook out the raw flour taste.
Gradually whisk in the chicken broth, making sure to break up any lumps until the mixture is smooth and begins to thicken slightly.
Stir in the heavy cream until fully incorporated and the sauce is creamy.
Add the sour cream and whisk gently until smooth.
Season the sauce with Italian seasoning, dried parsley flakes, thyme, paprika, onion powder, salt, and black pepper. Stir to combine.
Gently whisk in the chopped carrots, red pepper, frozen peas, and drained pimentos into the sauce.
Return the reserved mushroom and vegetable mixture back into the frying pan with the sauce. Mix gently to combine.
Stir in the chopped or shredded turkey meat into the sauce mixture.
Meanwhile, cook the linguini or spaghetti in the large pot of boiling water for approximately 5 minutes only. The pasta should be significantly undercooked as it will continue to cook in the oven. Drain well.
Add the partially cooked pasta directly into the turkey and sauce mixture in the frying pan. Toss gently to ensure all the pasta is coated.
Prepare a large casserole or baking dish (approx. 9×13 inches) by lightly coating it with cooking spray.
Pour the entire turkey tetrazzini mixture evenly into the prepared baking dish.
Sprinkle the finely shredded cheddar cheese uniformly over the top of the pasta mixture.
Next, sprinkle the Parmesan cheese evenly over the cheddar layer.

Prepare the Buttercrumb Topping

In a small bowl, combine the panko breadcrumbs with the garlic powder, paprika, and salt. Pour in the melted butter and toss until the breadcrumbs are evenly coated.
Generously sprinkle this garlic buttercrumb topping over the layers of cheddar and Parmesan cheeses in the casserole dish.

Bake the casserole in a preheated oven at 350 degrees F (175 degrees C) for 45 minutes, or until the casserole is bubbly and heated through.

For an extra golden and crispy topping, turn on the broiler during the last 5 minutes of baking. Keep a close eye on it to prevent burning.

Serving Suggestions and Storage Tips

This hearty Cheesy Turkey Tetrazzini is a complete meal in itself, but it pairs wonderfully with a few simple accompaniments. A crisp green salad with a light vinaigrette provides a refreshing counterpoint to the richness of the casserole. A side of steamed green beans or asparagus can add additional fresh vegetables. For those who can’t get enough bread, a crusty baguette or garlic bread is perfect for soaking up any extra creamy sauce.

Storage: Leftover tetrazzini stores beautifully. Allow the casserole to cool completely before transferring it to an airtight container. It can be refrigerated for up to 3-4 days. To reheat, portion individual servings and microwave until warm, or cover the entire casserole dish with foil and reheat in a 300°F (150°C) oven until thoroughly heated.

Freezing: Turkey Tetrazzini is also an excellent candidate for freezing. You can freeze it either baked or unbaked.

To Freeze Unbaked: Assemble the casserole up to the point of adding the breadcrumb topping. Cover tightly with plastic wrap, then a layer of aluminum foil. Freeze for up to 2-3 months. When ready to bake, thaw overnight in the refrigerator, then add the breadcrumb topping and bake as directed, potentially adding an extra 10-15 minutes to the baking time to ensure it’s heated through.
To Freeze Baked: Allow the baked casserole to cool completely. You can either freeze it whole (if it fits in your freezer-safe dish) or portion it into individual servings in freezer-safe containers. Cover tightly and freeze for up to 2-3 months. Thaw in the refrigerator overnight and reheat gently in the oven or microwave.
