Easy Chicken Tetrazzini Recipe
Classic chicken tetrazzini has been around forever and for good reason! It’s ridiculously good, easy to prepare, kid-friendly and reheats well. It’s sometimes made with soup flavor packets or canned soup, but my friends, you don’t need those to make this flavorful meal. I based this winning recipe on my popular Chicken and Mushroom Casserole recipe. The simple ingredients add all the creamy delicious flavor, and it’s nice to know there aren’t any mystery ingredients in the dish.
When you bake this Chicken Tetrazzini pasta casserole, some of the sauce bakes into the pasta, the flavors marry and [!!BAM!!] something wonderful happens. You’ll know what I mean when you try it. P.S. you can further simplify this by using rotisserie chicken – You’re welcome ‘ma friends :).
This Chicken Tetrazzini is one of my most popular pasta dishes, along with my Cajun Chicken Pasta, American Goulash, and Lasagna.

Ingredients for Chicken Tetrazzini
These ingredients for Chicken Tetrazzini are simple fridge and pantry staples that combine in the perfect way.
- Pasta – I’ve made this with linquine and thin spaghetti, but you I used thin spaghetti, but you can use your favorite noodles.
- Shredded chicken – I like using 4 cups of shredded rotisserie chicken to keep it simple, but you can cook the chicken breast (instructions below). Light or dark meat will work here.
- Mushrooms – White mushrooms are nice for their neutral color. Rinse (yes, it’s ok to rinse mushrooms for sauteeing) and dry the mushrooms, then slice thickly.
- Aromatics – onion and garlic add great flavor to the sauce.
- For the Roux – You’ll need butter and flour, which thicken the sauce.
- Chicken Broth – I opt for low-sodium chicken broth for tetrazzini. Regular chicken broth is ok, but go easy on the salt and add more to taste when making the sauce.
- To Build Flavor – salt, pepper, parsley, and lemon juice help brighten up the casserole.
- Half and Half – You can also make your own by substituting equal parts milk and heavy cream.
- Cheese – Mozzarella cheese is my favorite to use here. The cheese seals in the moisture in the casserole.
Pick the Correct Pasta
Skip the value-brand pasta or pasta that is mass-produced like Barilla for this recipe since it can absorb too much water and seem mushy or dry. Choose bronze-cut, higher-quality pasta made with hardier Durum wheat semolina flour that will stand up to baking (these are easily found in your grocery aisle, like De Cecco, Rustichella d’Abruzzo, Garofalo, Liguori, and others).
Variations for Chicken Tetrazzini
- Protein – swap leftover turkey, or even tuna for the baked chicken breast
- Veggies – You can easily substitute the mushrooms and dice up your favorite veggie to add with the onion. Try sauteed red peppers, steamed broccoli florets, artichoke hearts, fresh spinach, or frozen carrot/pea mix.
- Cheese – experiment with other cheeses like Havarti, cheddar, Monterey Jack, or pepper jack. Or you could add a sprinkle of parmesan cheese on top.
How to Make Chicken Tetrazzini
Traditionally, tetrazzini is made in a 13×9″ casserole dish, but it can also be done entirely using a Dutch oven so it can go from the stove to the oven saving you some dishes.
- Preheat oven to 350˚F and then grease your baking dish if using (9×13 baking dish, or two 9″ squares). **If cooking the chicken breasts instead of using rotisserie chicken, see my directions below for prepping the chicken.
- Cook Pasta in salted water until barely al dente. The pasta will continue to cook when in the oven, so don’t overcook it here. Reserve 1/2 cup of the pasta cooking water, and then drain the rest and set the pasta aside.
Natasha’s Pro Tip:
Salting the pasta water is so important for taste, but also for texture. Well-salted pasta water should taste like the ocean (about 1 Tbsp for 4 quarts of water).
- Saute the veggies – Soften the mushrooms with some olive oil then add the onions and saute until golden (5 minutes). Finally, add garlic and cook another minute then transfer the mixture to a plate.
- Make the sauce in the same skillet as cooking the veggies. Melt the butter and then add the flour, whisking for 1-2 minutes to get rid of the flour taste. It should look golden and smell a bit nutty. While whisking, slowly drizzle in the chicken broth then lemon juice and season with salt and pepper.
- Combine the Casserole – into the pot with the drained pasta, add chicken, veggies, pasta, sauce and stir together. I like to add about 1/4 cup of the reserved pasta water for a creamier sauce. Spread into the buttered casserole and sprinkle with the cheese.
- Bake covered in foil or a lid in the oven for 20 minutes, and then remove the foil and cook another 15 minutes. For a crispier topping, broil for a minute or two. Serve!

How to Cook Chicken Breast for Pasta Casseroles
It’s easy to substitute the rotisserie chicken in this chicken tetrazzini recipe for chopped chicken breast. You can use baked chicken breast or sautee 1 1/2 lbs of chicken breast. If the chicken breasts are very large, you can cut them in half crosswise for faster cooking.
- Add 1 Tbsp of oil in a large Dutch oven pot (I can use this same pot to make the veggies and sauce and cook the casserole- Easier cleanup!)
- Sprinkle salt and pepper over both sides of the chicken breasts and sautee about 4-5 minutes per side or until golden brown and cooked through to 165˚F on a thermometer. Chop into 1″ pieces. Proceed to the recipe!
Make-Ahead and Storage Tips
It’s simple to serve Chicken Tetrazzini ahead and also to store leftovers. This is one of my favorites to bring to friends or freeze for another night.
- Make-Ahead: Mix the casserole and place it in a freezer-safe, oven-safe dish, but don’t top it with cheese. Store in the fridge for 5 days or in the freezer for 6 months. When ready to serve, thaw in the fridge overnight, top with cheese and cook. You may have to add a few minutes to the bake time.
- To Refrigerate: Allow leftovers to cool completely, then cover and store in the fridge for up to 4 days.
- Freezing: Cover and freeze cooled leftovers for up to 6 months. Thaw in the fridge overnight before reheating.
- To Reheat: Place casserole covered in a 350°F oven for 15 minutes or until warmed through.

For the Chicken Tetrazzini:
Prevent your screen from going dark
-
Preheat Oven to 350˚F and butter a 9×13 Casserole dish.
-
Cook pasta in a large pot of salted boiling water (it should taste like ocean water) and cook until barely al dente according to package instructions – do not overcook. Reserve 1/2 cup of pasta cooking water, then drain the pasta, partially cover, and set aside.
-
Saute the Veggies: Place a large skillet over medium/high heat. Add oil then add sliced mushrooms and sauté 3 min or until softened. Add diced onions and cook until onions are soft and golden, 5-7 min. Add minced garlic and sauté another 1 min until fragrant. Transfer to the cutting board with chicken.
-
Make the Sauce: In the same pot, melt butter and whisk in flour until lightly golden (1 1/2 min). Slowly whisk in chicken broth, lemon juice, salt, and pepper and whisk until smooth. Add half and half and bring to a simmer. Season the sauce with more salt and pepper to taste.
-
Combine the Casserole: Into the pasta pot, add the chicken, mushrooms mixture, parsley, and all of your sauce. Stir to combine. You can add 1/2 cup of reserved pasta water to make it saucier then spread it evenly into your prepared casserole dish. Sprinkle the top generously with mozzarella.
-
To Bake: Cover with foil and bake at 350˚F for 20 min, then remove the lid and continue baking for 15 min. You can broil for the last 1-2 minutes to get some golden spots on top.
*To cook your own chicken: in your dutch oven or pot, add 1 Tbsp oil over medium-high heat. Season 1.5 lbs chicken breasts with salt and pepper. Saute chicken until golden brown on both sides and cooked through (about 4 min per side). If chicken breasts are very large, cut them in half lengthwise for even cooking. Remove to cutting board to cool, then cut into bite-sized pieces.
Make Ahead and Storage
- Make Ahead – assemble the casserole, but cover and store in the fridge for 5 days or the freezer for up to 6 months before baking. Thaw in the fridge overnight and then add cheese and cook as directed.
- Leftovers – allow leftovers to cool completely, then cover and store in the refrigerator for 5 days or freeze for up to 6 months. Thaw in the fridge overnight and then warm in a 350°F oven until heated through.
