Why Make This Chicken Tetrazzini Recipe at Home
Homemade Chicken Tetrazzini tastes fresher, creamier, and more flavorful than anything from a box or freezer aisle. You control the salt, the veggies, the cheese level, and how saucy you want it, so every bite hits exactly how you like it.
This recipe also stretches leftover chicken into a full meal that feeds a crowd. You can prep it earlier in the day, stash it in the fridge, then bake it when everyone starts asking what smells so good.
My whole family scraped the pan clean and asked for it again the next night, which never happens with leftovers ★★★★★
Ingredients You Need
Pasta and Protein
- 12 ounces spaghetti or linguine
- Use regular or thin spaghetti; avoid very delicate pasta so it holds up in the oven.
- 3 cups cooked chicken, shredded or diced
- Rotisserie chicken saves time and adds flavor.
- Leftover baked or grilled chicken also works great.
Veggies and Aromatics
- 2 tablespoons olive oil
- 8 ounces mushrooms, sliced
- Cremini or baby bella mushrooms give deeper flavor than white mushrooms.
- 1 small onion, finely chopped
- 3 cloves garlic, minced
- 1 cup frozen peas
- No need to thaw; they heat in the sauce.
- Optional: 1 cup chopped spinach or kale for extra greens
Creamy Sauce
- 4 tablespoons unsalted butter
- 1/4 cup all purpose flour
- 2 1/2 cups chicken broth
- Use low sodium broth so you control the salt.
- 1 cup whole milk
- 1/2 cup heavy cream
- You can swap this with more milk for a lighter version, but the sauce turns less rich.
- 1/2 cup sour cream or plain Greek yogurt
- Sour cream gives a classic tang; Greek yogurt adds protein and still tastes great.
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon dried thyme or Italian seasoning
- 1/4 teaspoon paprika
Cheese and Topping
- 1 cup shredded mozzarella cheese
- 1 cup shredded Parmesan cheese, divided
- Use a wedge of Parmesan and grate it if possible; it melts and tastes better than the green can.
- 1 cup panko breadcrumbs
- 2 tablespoons melted butter
- 1 tablespoon chopped fresh parsley for garnish
Pantry Shortcuts and Substitutions
- Use canned mushrooms if you feel rushed; drain them well before you add them.
- Use a cream of chicken soup shortcut if you want: skip the flour, milk, and cream, and stir in 2 cans of condensed cream of chicken soup with 1 1/2 cups broth.
- Swap peas with mixed frozen veggies if that is what you have.
- Use gluten free pasta and gluten free flour to keep it gluten free.
Equipment List
- Large pot for boiling pasta
- Large skillet or sauté pan
- Whisk
- 9×13 inch baking dish
- Mixing bowls
- Cutting board and knife
- Cheese grater
- Aluminum foil
Tips & Mistakes
- Salt the pasta water generously so the noodles taste seasoned, not bland.
- Cook the pasta to just shy of al dente, since it continues cooking in the oven.
- Brown the mushrooms well so they develop flavor instead of steaming in their own liquid.
- Whisk the flour into the butter fully so the sauce turns smooth and never gritty.
- Add the broth slowly while you whisk so the sauce stays lump free.
- Taste the sauce before you mix in the pasta and chicken, and adjust salt and pepper right then.
- Do not drown the pasta in sauce; aim for creamy and coated, not soupy.
- Spread the mixture evenly in the baking dish so it heats at the same rate.
- Cover with foil for the first part of baking so the top does not burn before the center heats.
- Let the casserole rest for 10 minutes after baking so it sets and slices cleanly.
How to Make Chicken Tetrazzini
1: Cook the Pasta
Bring a large pot of salted water to a boil. Add the spaghetti and cook it until it reaches just shy of al dente, usually 1 to 2 minutes less than the package suggests. Drain the pasta and toss it with a drizzle of olive oil so it does not stick while you make the sauce.
2: Sauté the Veggies
Heat 2 tablespoons olive oil in a large skillet over medium high heat. Add the sliced mushrooms and cook them until they release their liquid and turn golden around the edges, about 6 to 8 minutes. Stir in the chopped onion and cook until it softens and turns translucent, then add the garlic and cook for 30 seconds until fragrant.
3: Build the Roux
Push the veggies to one side of the pan and add 4 tablespoons butter to the empty side. Once the butter melts, sprinkle the flour over it and whisk it into a smooth paste. Stir the veggies back into the roux so everything coats evenly.
4: Add Liquids and Seasonings
Slowly pour in the chicken broth while you whisk constantly. Add the milk and heavy cream, then keep whisking until the sauce turns smooth and starts to thicken, about 4 to 5 minutes. Stir in the salt, pepper, garlic powder, onion powder, thyme or Italian seasoning, and paprika.
5: Finish the Creamy Sauce
Turn the heat to low. Stir in the sour cream or Greek yogurt until it blends fully and the sauce turns silky. Add 1/2 cup Parmesan and 1/2 cup mozzarella, then stir until the cheese melts and the sauce looks glossy and thick.
6: Add Chicken, Peas, and Pasta
Stir the cooked chicken into the sauce, then add the frozen peas and any optional greens. Fold in the cooked pasta and toss until every strand coats in the creamy mixture. Taste again and adjust seasoning with more salt or pepper if you want.
7: Assemble the Casserole
Preheat your oven to 350°F. Lightly grease a 9×13 inch baking dish, then pour in the chicken and pasta mixture and spread it into an even layer. Sprinkle the remaining 1/2 cup mozzarella and 1/2 cup Parmesan over the top.
8: Add the Crunchy Topping
In a small bowl, mix the panko breadcrumbs with 2 tablespoons melted butter. Scatter the buttery crumbs over the cheese layer. This topping gives that perfect crunchy contrast to the creamy pasta underneath.
9: Bake
Cover the baking dish with foil and bake for 20 minutes. Remove the foil and bake for another 10 to 15 minutes until the top turns golden and the edges bubble. Pull the dish from the oven and let it rest for 10 minutes so the sauce thickens slightly and slices hold together.
10: Garnish
Sprinkle chopped fresh parsley over the top for color and a fresh note. Scoop generous portions with a large spoon or cut into squares for neater servings. Watch it disappear faster than you thought possible.
Variations I’ve Tried
I swap the chicken with leftover turkey after holidays and it tastes just as cozy, maybe even better. I also tried a veggie version with sautéed mushrooms, broccoli, and spinach and skipped the meat entirely, which worked great for meatless Monday. Sometimes I stir in a little cooked bacon or pancetta for a smoky twist that my kids request often.
I tested a lighter version with all milk instead of cream and Greek yogurt instead of sour cream, and it still tasted creamy, just a bit less rich. I also tried a spicy version with red pepper flakes and pepper jack cheese for friends who love heat. Gluten free pasta and gluten free breadcrumbs also worked nicely, as long as I cooked the pasta slightly under so it did not turn mushy.
How to Serve Chicken Tetrazzini
Serve Chicken Tetrazzini Recipe hot with a simple green salad or steamed broccoli to balance the richness. Garlic bread or warm dinner rolls make perfect partners, since everyone loves to scoop up any extra sauce. You can also add a side of roasted carrots or green beans for more veggies and color on the plate. I like to top each serving with a little extra grated Parmesan and a sprinkle of parsley for a restaurant style finish.
How to store
- Cool leftovers to room temperature within 1 hour, then store them in an airtight container in the fridge for up to 4 days.
- For freezing, portion the Chicken Tetrazzini into freezer safe containers, label with the date, and freeze for up to 3 months.
- Reheat single portions in the microwave with a splash of milk or broth, covered, until hot, then stir and heat again if needed.
- Reheat larger portions in a covered baking dish at 325°F, with a little extra broth or milk stirred in, until the center steams and the top warms through, then uncover for the last few minutes to crisp the topping again.
