Ingredients You’ll Need
Getting the ingredients right is the secret to this dish’s success. Each element plays an important role, from the hearty chicken to bring protein and richness, to the mushrooms that add a savory earthiness, all tied together by a creamy sauce that coats every strand of pasta with flavor and comfort.
- 12 oz linguine or spaghetti: Choose a quality durum wheat pasta to prevent sogginess for the perfect texture.
- 4 cups rotisserie chicken, shredded or diced: Rotisserie chicken makes this recipe incredibly easy without sacrificing taste.
- 2 Tbsp olive oil: For sautéing and adding a subtle fruity richness to the veggies.
- 1 lb button mushrooms, thickly sliced: They bring meaty texture and an earthy depth.
- 1 medium onion, finely chopped: Adds sweetness and balances the savory flavors.
- 4 garlic cloves, minced: Garlic lifts everything with aromatic warmth and flavor.
- 4 Tbsp unsalted butter: Essential for making the roux that thickens the sauce beautifully.
- 1/3 cup all-purpose flour: Helps create that silky, creamy sauce base.
- 3 cups low-sodium chicken broth: Brings a subtle savoriness without overwhelming saltiness.
- 1 Tbsp lemon juice: A bright note that cuts through the richness.
- 2 cups half & half (or equal parts milk & heavy cream): This combination adds luscious creaminess.
- 1 1/2 tsp sea salt: Balances the flavors perfectly.
- 1/4 tsp freshly ground black pepper: Adds just the right amount of spice.
- 1/4 cup parsley, chopped: Provides fresh color and a mild herbaceous lift.
- 1 1/2 cups shredded mozzarella cheese: Melts into a gooey, golden topping that’s utterly irresistible.
How to Make Chicken Tetrazzini Recipe
Step 1: Cook the Pasta
Start by bringing a large pot of salted water to a boil—make sure the water tastes like the ocean because that’s the secret for perfectly seasoned pasta. Cook your linguine or spaghetti just until barely al dente, meaning it’s still a tiny bit firm in the center. This helps the pasta hold up beautifully under the creamy sauce without turning mushy once baked. Reserve half a cup of the pasta water before draining, then set the pasta aside, partially covered to keep warm.
Step 2: Sauté the Vegetables
Warm olive oil in a large skillet over medium-high heat, then add your thickly sliced button mushrooms. Sauté them for about 3 minutes until they start to soften and release their lovely, earthy aroma. Next, toss in finely chopped onions and cook until they become soft and golden, about 5 to 7 minutes. Finally, add minced garlic and sauté for just another minute until fragrant—this creates a flavorful base that perfectly complements the chicken and sauce. Transfer this delicious mixture to a cutting board alongside your chicken.
Step 3: Make the Creamy Sauce
In the same pot you cooked the pasta in, melt the unsalted butter over medium heat. Whisk in the flour thoroughly until it turns lightly golden, about a minute and a half—this is your roux that thickens the sauce to velvety perfection. Slowly pour in the chicken broth, lemon juice, sea salt, and freshly ground black pepper, whisking continuously for a smooth consistency. Add the half & half (or milk and cream mix), then bring the sauce to a gentle simmer. Taste and adjust seasoning if needed to get that perfect balance of savory and creamy.
Step 4: Combine Everything
Into the pot with the sauce, add the cooked pasta, shredded chicken, sautéed mushroom and onion mixture, and chopped parsley. Stir everything gently to combine, ensuring every strand of pasta and chunk of chicken is coated in that luscious sauce. If you want a saucier consistency, gently stir in the reserved pasta water. Then pour this mixture evenly into a buttered 9×13 casserole dish, spreading it out nicely. Finally, sprinkle the shredded mozzarella cheese generously on top—this will create a golden, bubbly crust that’s irresistible.
Step 5: Bake to Perfection
Cover your casserole dish with foil and bake in a preheated 350˚F oven for 20 minutes to allow the flavors to meld and the sauce to thicken beautifully. Remove the foil and continue baking uncovered for another 15 minutes, giving the cheese a chance to brown and bubble perfectly. For an ultra-golden, crispy top, broil for an additional 1 to 2 minutes but watch carefully so it doesn’t burn. Let it cool slightly before digging in!
How to Serve Chicken Tetrazzini Recipe
Garnishes
Fresh parsley sprinkled on top adds that perfect pop of color and light herbal flavor that brightens each bite. For a subtle hint of extra richness, a light dusting of freshly grated Parmesan cheese can elevate your dish effortlessly.
Side Dishes
This creamy chicken tetrazzini pairs exceptionally well with crisp green salads dressed lightly in lemon vinaigrette, which cuts through the richness. Garlic roasted asparagus or green beans provide fresh, crunchy contrast to the soft, cheesy casserole, balancing the meal wonderfully.
Creative Ways to Present
For a fun twist, serve the Chicken Tetrazzini Recipe in individual ramekins for impressive single servings that show off those gooey, golden tops. You can also layer the casserole with baby spinach or swap mozzarella with Gruyère for a nutty, sophisticated flavor. Adding a sprinkle of toasted breadcrumbs before the final bake adds a lovely crunchy texture that guests will adore.
Make Ahead and Storage
Storing Leftovers
After enjoying your Chicken Tetrazzini Recipe, allow any leftovers to cool completely before covering tightly and refrigerating. They’ll keep fresh for up to 5 days, making it an excellent option for meal prep or easy lunches during your busy week.
Freezing
This casserole freezes wonderfully. Assemble your entire dish but don’t add the cheese topping before freezing. Wrap tightly and freeze for up to 6 months. When ready, thaw overnight in the refrigerator and then add cheese before baking to fresh perfection.
Reheating
To reheat leftovers, place them in a 350˚F oven until warmed through—this usually takes about 20-25 minutes. Cover with foil to prevent drying out, removing the foil in the last 5 minutes if you want to refresh that golden cheese crust. Avoid microwaving if possible to keep the texture just right.
FAQs
Can I use a different type of pasta for Chicken Tetrazzini Recipe?
Absolutely! While linguine or spaghetti works beautifully, you can use other long pastas like fettuccine or even short pasta like penne if you prefer. Just be sure to cook it just shy of al dente to avoid mushiness once baked.
Is rotisserie chicken necessary or can I cook chicken myself?
Rotisserie chicken is a fantastic shortcut, but cooking your own chicken breast works just as well. Simply sauté seasoned chicken breasts until cooked through, then shred or dice before adding to the dish.
Can I make this recipe dairy-free?
Yes! Substitute the half & half with a dairy-free cream alternative and use a dairy-free cheese substitute. Keep in mind that this will slightly change the classic flavor and texture but can still be delicious.
How do I avoid a watery casserole?
Using good quality durum wheat pasta that holds its shape helps, and cooking it to al dente keeps it firm. Also, don’t skip the step of thickening the sauce properly with a roux; this creates a creamy, not watery, texture in your casserole.
Can I add vegetables to this Chicken Tetrazzini Recipe?
Definitely! Peas, spinach, or even roasted red peppers make wonderful additions that boost color, texture, and nutrition without overpowering the creamy, comforting base of the dish.

- Total Time: 1 hour 5 minutes
- Yield: 9 servings
Ingredients
For the Chicken Tetrazzini:
- 12 oz linguine or spaghetti
- 4 cups rotisserie chicken, shredded or diced (or cook 1.5 lbs chicken breast)
- 2 Tbsp olive oil
- 1 lb button mushrooms, thickly sliced
- 1 medium onion, finely chopped
- 4 garlic cloves, minced
For the Creamy Sauce:
- 4 Tbsp unsalted butter
- 1/3 cup all-purpose flour
- 3 cups low-sodium chicken broth
- 1 Tbsp lemon juice
- 2 cups half & half (or equal parts milk & heavy cream)
- 1 1/2 tsp sea salt, plus more to taste
- 1/4 tsp black pepper, freshly ground
- 1/4 cup parsley, chopped, plus more to garnish
- 1 1/2 cups shredded mozzarella cheese
Instructions
- Preheat and Prepare: Preheat your oven to 350˚F and butter a 9×13-inch casserole dish to prevent sticking.
- Cook Pasta: Boil a large pot of salted water until it tastes like ocean water, then add the linguine or spaghetti. Cook until barely al dente according to package instructions, being careful not to overcook. Reserve 1/2 cup of the pasta water for later use, then drain the pasta, partially cover, and set aside.
- Sauté Vegetables: Heat a large skillet over medium-high heat and add olive oil. Add the sliced mushrooms and sauté for about 3 minutes until softened. Add the finely chopped onion and cook for 5-7 minutes until soft and golden. Stir in the minced garlic and sauté for an additional 1 minute until fragrant. Transfer this mixture to a cutting board and combine with the shredded chicken.
- Make the Sauce: In the same pot used for pasta, melt the unsalted butter over medium heat. Whisk in the flour and cook for about 1 1/2 minutes until lightly golden to form a roux. Gradually whisk in the chicken broth, lemon juice, salt, and pepper until the sauce is smooth. Stir in the half & half and bring to a simmer. Adjust seasoning by adding more salt and pepper to taste.
- Combine Casserole Ingredients: Add the chicken and mushroom mixture, chopped parsley, and sauce to the pot with the cooked pasta. Stir everything together evenly. If the mixture seems dry, add reserved pasta water up to 1/2 cup to loosen it. Transfer the entire mixture evenly to the prepared casserole dish and sprinkle the shredded mozzarella cheese over the top.
- Bake: Cover the casserole dish with foil and bake at 350˚F for 20 minutes. Remove the foil and continue baking for another 15 minutes. For a golden, bubbly topping, broil the casserole for 1-2 minutes at the end, watching carefully to prevent burning.
Notes
- Selecting Pasta – Choose durum wheat semolina, bronze-cut pasta to avoid absorbing too much water and becoming dry in the casserole.
- To Cook Your Own Chicken – Season 1.5 lbs chicken breasts with salt and pepper. Heat 1 Tbsp oil in a Dutch oven or pot over medium-high heat and sauté chicken breasts about 4 minutes per side (cut in half lengthwise if large). Let cool before dicing.
- Make Ahead and Storage – Assemble the casserole and cover it. Store in the refrigerator for up to 5 days or freeze for up to 6 months. Thaw overnight in the fridge before baking and adding cheese.
- Leftovers – Cool leftovers completely, store in the fridge for 5 days or freeze up to 6 months. Reheat in a 350°F oven until warmed through.
