Chicken Tetrazzini Recipe serves cozy, creamy noodles loaded with tender chicken, savory mushrooms, and a crunchy, cheesy topping. It suits family dinners, game nights, or potlucks, and you can finish it in about 60 minutes. I learned my love for this casserole at Midwest potlucks, and my kids now judge all noodles by this pan.
Why Choose This Chicken Tetrazzini Recipe
This Chicken Tetrazzini Recipe delivers a from-scratch creamy mushroom sauce, a generous amount of chicken, and a golden, buttery crumb topping. I keep the sauce silky, not gluey, and I bake the pasta just long enough to bubble and brown. You can use rotisserie chicken, pantry pasta, and frozen peas, so weeknight dinner still feels special without extra fuss.
Ingredients You Need
- 12 ounces spaghetti or linguine; egg noodles also work
- 3 cups cooked chicken, chopped or shredded; rotisserie chicken makes it easy
- 8 ounces cremini or button mushrooms, sliced; canned mushrooms work in a pinch
- 1 small yellow onion, finely chopped
- 3 garlic cloves, minced
- 2 tablespoons olive oil
- 4 tablespoons unsalted butter, divided
- 1/3 cup all-purpose flour
- 2 1/2 cups low-sodium chicken broth; if using regular, hold back on salt
- 1 cup whole milk; evaporated milk works for a lighter swap
- 1/2 cup heavy cream or half-and-half
- 1/2 cup sour cream or 4 ounces cream cheese, softened
- 1 cup shredded mozzarella or Monterey Jack
- 1 cup grated Parmesan, divided
- 1/2 cup dry white wine; use more broth if you skip wine
- 1 teaspoon kosher salt, plus more for pasta water
- 1/2 teaspoon black pepper
- 1/2 teaspoon dried thyme or Italian seasoning
- 1/4 teaspoon ground nutmeg, optional
- 1 cup frozen peas, thawed, or 1 1/2 cups small broccoli florets, blanched
- Topping: 1 cup panko breadcrumbs mixed with 2 tablespoons melted butter and 2 tablespoons grated Parmesan; crushed buttery crackers also work
- Finishes: chopped parsley and a little lemon zest
Pantry shortcut option: swap the flour, milk, and cream with two cans condensed cream of mushroom soup plus 1 cup broth, then adjust salt.
Equipment
- Large pot for pasta and a colander
- 12-inch skillet or Dutch oven
- 9×13-inch baking dish
- Whisk, wooden spoon, measuring cups, and foil
How to Make Chicken Tetrazzini Recipe
Step 1: Boil pasta and heat the oven
Preheat the oven to 375°F. Bring a large pot of salted water to a boil and cook pasta 2 minutes shy of al dente. Reserve 1/2 cup pasta water, then drain and toss pasta with a teaspoon of olive oil so it doesn’t clump.
Step 2: Sauté mushrooms and aromatics
Heat 1 tablespoon olive oil and 2 tablespoons butter in a large skillet over medium-high. Add mushrooms and cook until they brown and release most moisture, about 6 to 8 minutes. Stir in onion and cook until soft, about 3 minutes, then add garlic and thyme and cook 1 minute. Season with a pinch of salt and pepper, splash in the wine, and simmer until it reduces by half; transfer mixture to a bowl.
Step 3: Build the roux
Lower heat to medium, then melt the remaining 2 tablespoons butter in the same skillet. Sprinkle in the flour and whisk for 1 to 2 minutes until it smells toasty. Keep it pale blond so the sauce stays smooth.
Step 4: Make the creamy sauce
Whisk in the broth in a slow stream, then add milk and cream and keep whisking to smooth out any lumps. Simmer and stir until the sauce thickens enough to coat a spoon, about 4 to 6 minutes. Stir in sour cream, 3/4 cup Parmesan, mozzarella, nutmeg, and the mushroom-onion mixture. Taste and season with salt and pepper, then fold in peas.
Step 5: Add chicken and pasta
Add the chicken to the skillet and stir to coat. Add the pasta and toss gently until everything looks saucy. Splash in a little reserved pasta water if the mixture feels tight.
Step 6: Transfer and top
Grease a 9×13-inch baking dish and spoon the tetrazzini into it. Mix panko with melted butter and 2 tablespoons Parmesan and scatter over the top. Add a handful of extra mozzarella if you like a stretchier top.
Step 7: Bake, rest, and finish
Bake until bubbly around the edges and golden on top, 20 to 25 minutes. Broil for 1 to 2 minutes for deeper color, watching closely. Let the casserole rest 10 minutes, then garnish with parsley and a whisper of lemon zest.
Tips & Common Mistakes
- Salt the pasta water well; bland noodles mute the sauce.
- Undercook the pasta by 2 minutes; it will finish in the oven and stay tender, not mushy.
- Brown the mushrooms; pale mushrooms water down the sauce.
- Whisk the roux for a minute; raw flour flavor can linger if you rush.
- Add dairy off a hard boil; gentle heat keeps the sauce smooth.
- Keep extra broth handy; loosen thick sauce with a splash.
- Don’t skip the rest after baking; the casserole sets and slices cleanly.
- If the top browns fast, tent with foil and finish baking.
Variations I’ve Tried
- Turkey Tetrazzini: swap in leftover roast turkey after the holidays and stir in a handful of cranberries on the side, not in the pan.
- Spinach and Artichoke: fold in 2 cups chopped baby spinach and 1 cup quartered marinated artichokes.
- Broccoli Cheddar: skip mozzarella, add 1 1/2 cups small broccoli florets and 1 cup sharp cheddar.
- No-Mushroom: use extra onion and 1 cup diced celery for crunch and aroma.
- Lemon Herb: add 1 tablespoon lemon juice and fresh thyme or parsley for a brighter take.
- Gluten-Free: use gluten-free pasta and a 1:1 gluten-free flour blend for the roux; check your broth label.
- Lightened Up: use evaporated milk and Greek yogurt instead of cream and sour cream, then add a touch more broth to keep it silky.
How to Serve
Spoon big, cozy portions onto warmed plates and shower with fresh parsley. I like a crisp salad with a lemony vinaigrette and a side of garlic bread for crunch. Roasted green beans or asparagus play nice with the creamy sauce. A chilled glass of unoaked chardonnay or sparkling water with a lemon wedge rounds it out.
Make-Ahead and Storage
- Make-ahead unbaked: assemble, cool, cover tightly, and refrigerate up to 24 hours; bake covered for 20 minutes, uncover, then bake until golden, about 15 minutes more.
- Make-ahead baked: bake, cool, and refrigerate up to 4 days; reheat covered at 350°F until hot, about 20 minutes.
- Freezer: wrap the unbaked casserole tightly and freeze up to 3 months; thaw in the fridge overnight, then bake as directed. You can bake from frozen at 350°F, covered, 60 to 75 minutes, then uncover to brown.
- Reheat slices: microwave in short bursts with a splash of broth or milk, or warm in a covered skillet over low heat until creamy again.
