Chicken tetrazzini is one of those comforting casserole classics that turns leftover chicken into a silky, cheesy weeknight winner. Rich mushroom-and-cream sauce, tender pasta, and a golden breadcrumb top make it feel like a cozy family dinner or an elegant potluck contribution — depending on how fancy you get with the garnishes. I’ve made a version inspired by Geralyn Foster’s pinned recipe many times: it’s forgiving, fridge-friendly, and a perfect way to stretch a rotisserie bird. If you like easy, creamy mains, you might also enjoy this savory garlic butter salmon recipe for another weeknight favorite.

Why you’ll love this dish

This chicken tetrazzini recipe shines because it’s both comforting and flexible. You get a creamy, flavored sauce that clings to every noodle, crunchy browned topping, and pockets of tender shredded chicken — all in one bake-and-forget casserole. It’s the kind of dish that feeds a crowd, packs well for lunches, and scales up without fuss.

“The sauce is the heart of this dish — velvety, garlicky, and studded with mushrooms. It made every skeptic at my dinner table ask for seconds.”
— A home cook who swapped canned soup for a scratch-made béchamel

Perfect occasions: family dinners, potlucks, cozy weeknights, or a make-ahead holiday side that’s still hearty enough to be the main. It’s budget-friendly when you use leftover or rotisserie chicken and pantry staples.

The cooking process explained

Before you start, here’s the overall flow so you know what to expect: sauté aromatics and mushrooms, build a creamy roux-based sauce (or use a lighter broth-milk combo), toss sauce with cooked pasta and cooked chicken, transfer to a baking dish, top with cheese and breadcrumbs, and bake until bubbly and golden. The hands-on time is primarily sauce-making and sautéing; assembly and oven time are mostly passive.

Timing overview:

• Prep and cook pasta and chicken: 15–20 minutes (less if using leftovers)
• Sauce and assembly: 15–20 minutes
• Bake: 20–30 minutes
  Total active time: ~35–45 minutes. Total time: ~1 hour.

What you’ll need

• 12 oz spaghetti or egg noodles (use gluten-free pasta if needed)
• 3 cups cooked chicken, shredded or diced (rotisserie chicken works great)
• 8 oz cremini or button mushrooms, sliced
• 1 medium onion, finely chopped
• 2–3 cloves garlic, minced
• 4 tbsp unsalted butter
• 3 tbsp all-purpose flour (substitute 3 tbsp cornstarch for gluten-free)
• 2 cups low-sodium chicken broth
• 1 cup whole milk or half-and-half (use oat milk + a bit extra butter for dairy-free)
• 1 cup freshly grated Parmesan cheese (plus extra for topping)
• 1 tsp Dijon mustard (optional, brightens the sauce)
• 1/2 tsp dried thyme or 1 tsp chopped fresh thyme
• Salt and freshly ground black pepper, to taste
• 1 cup panko breadcrumbs mixed with 2 tbsp melted butter for topping
• 2 tbsp chopped fresh parsley for garnish

Ingredient notes/substitutions inline:

• Mushrooms: baby bella add more umami; skip for a creamy chicken-only version.
• Cheese: Gruyère melts beautifully if you want a nuttier flavor.
• Noodles: egg noodles give a classic feel; spaghetti works well and is what many versions use.

Step-by-step instructions

1. Preheat your oven to 375°F (190°C). Butter a 9×13-inch baking dish or a similar casserole pan.
2. Cook pasta in salted boiling water until just al dente (about 1 minute shy of package time). Drain and set aside — a slightly undercooked pasta keeps the bake from going mushy.
3. In a large skillet over medium heat, melt 2 tbsp butter. Add the chopped onion and a pinch of salt; sauté until translucent, about 4–5 minutes. Add the mushrooms and cook until their liquid evaporates and they brown, about 6–8 minutes.
4. Stir in the garlic and cook 30 seconds until fragrant.
5. Push veggies to one side, add remaining 2 tbsp butter to the skillet. Sprinkle the flour over the butter and whisk to form a roux. Cook 1–2 minutes to take off the raw flour taste.
6. Gradually whisk in chicken broth, scraping up browned bits. Add the milk/half-and-half, Dijon (if using), thyme, and bring to a gentle simmer. Cook until the sauce thickens enough to coat the back of a spoon, 3–5 minutes. Taste and season with salt and pepper. Stir in 3/4 cup of the Parmesan.
7. Remove from heat and fold in the cooked chicken and drained pasta, ensuring everything is evenly coated.
8. Transfer mixture to prepared baking dish. Sprinkle remaining Parmesan evenly over the top, then scatter the panko-butter mixture for a crisp golden finish.
9. Bake uncovered for 20–25 minutes, until bubbling and the top is golden. For an extra-crispy top, broil 1–2 minutes — watch closely to avoid burning.
10. Let rest 5 minutes. Sprinkle with chopped parsley before serving.

Best ways to enjoy it

Serve chicken tetrazzini hot from the oven with a simple green salad (peppery arugula with a lemon vinaigrette cuts through the richness), roasted green beans, or buttered peas for a classic pairing. For a full-menu pairing that ends on a sweet note, consider serving a light fruit dessert like this strawberry obsession dessert to brighten the meal.

Plating ideas:

• Spoon into warmed shallow bowls and top with extra Parmesan and a lemon twist.
• For family-style, bake in a pretty casserole and bring straight to the table for rustic appeal.
• Make individual ramekins for elegant, single-serve presentations.

Storage and reheating tips

• Refrigerator: Cool completely, cover tightly, and refrigerate for up to 3–4 days. Label with the date.
• Freezing: Assemble (but don’t top with breadcrumbs) and freeze covered for up to 2 months. Thaw overnight in the fridge before finishing with breadcrumbs and baking.
• Reheating from fridge: Reheat individual portions in a 350°F (175°C) oven for 15–20 minutes until hot. Microwave works in a pinch — cover and reheat on medium power in 1–2 minute increments, stirring once for even heat.
• Reheating from frozen: Thaw overnight, then bake at 350°F (175°C) for 25–35 minutes covered with foil, remove foil and bake until top is golden.
  Food safety note: Reheat to an internal temperature of 165°F (74°C) before serving.

Pro chef tips

• Don’t overcook the pasta: undercook by one minute and it will finish perfectly in the oven.
• Build flavor in the base: brown the mushrooms and scrape up fond before making the sauce — those browned bits add depth.
• Use freshly grated Parmesan: pre-grated cheese often contains anti-caking agents and won’t melt as smoothly.
• Control richness: swap some milk for low-sodium broth to keep it lighter without losing creaminess.
• Crisp topping trick: mix panko with a touch of melted butter and a teaspoon of finely grated Parmesan — it browns beautifully.
• Make it ahead: you can assemble the casserole, cover tightly, and refrigerate for up to 24 hours before baking. Add breadcrumbs just before baking for maximum crunch.

Creative twists

• Mushroom-forward: double the mushrooms and add a splash of white wine when sautéing for a deeper flavor.
• Shrimp tetrazzini: swap chicken for cooked shrimp, reduce baking time, and stir shrimp in at the end so they don’t overcook.
• Vegetarian: replace chicken with roasted cauliflower, artichoke hearts, or a medley of bell peppers and sun-dried tomatoes.
• Gluten-free: use gluten-free pasta and a slurry of cornstarch + cold water instead of flour to thicken the sauce.
• Dairy-free: use a plant-based milk (unsweetened oat or soy), dairy-free butter, and nutritional yeast for a cheesy vibe.
• Individual servings: bake in ramekins for 12–15 minutes for personal portions — great for dinner parties.

Common questions

Q: Can I use rotisserie chicken or leftover chicken?
A: Yes — rotisserie chicken is ideal. Using pre-cooked chicken saves time and adds great flavor. Fold it in near the end of the sauce process so it warms through but doesn’t dry out.

Q: How long does the assembled casserole last in the fridge?
A: Store covered in the refrigerator for 3–4 days. Reheat to 165°F (74°C) before serving. If you need longer storage, freeze for up to 2 months (see freezing tips above).

Q: Can I make this ahead for a party?
A: Absolutely. Assemble the casserole, cover tightly, and refrigerate up to 24 hours. Add the breadcrumb topping right before baking so it stays crisp.

Q: What’s the best pasta for tetrazzini?
A: Egg noodles are traditional because their wide shape holds sauce well; spaghetti and short twists like rotini or penne also work. Use a sturdier noodle if you plan to reheat leftovers.

Q: How can I make it lighter without losing flavor?
A: Replace half the milk/cream with low-sodium chicken broth, use less cheese, and add more mushrooms and vegetables for volume. A squeeze of lemon at the end brightens the dish without extra calories.
