This easy chicken tetrazzini is a creamy baked pasta dish that never fails to win over both kids and adults at my table. Loaded with tender chicken and gooey cheese, it is the kind of comfort food you crave on busy nights or whenever you need something hearty with minimal fuss.
The first time I made this, my oldest son polished off two helpings and asked for the leftovers in his lunchbox. It is now a must at every family gathering when I want something low effort but guaranteed to impress.
Ingredients
- Butter: provides richness and keeps everything moist choose unsalted for better control of seasoning
- Cream of chicken soup: brings creaminess and a savory backbone look for a good quality brand or make your own if you have extra time
- Sour cream: adds tang for balance opt for full fat for the best texture and flavor
- Chicken broth or stock: creates a silky sauce and enhances chicken flavor homemade or low sodium is ideal
- Salt and black pepper: round out and lift the flavors always taste and adjust before baking
- Cooked chicken: chopped for bite size tenderness rotisserie or leftover roasted chicken works perfectly
- Linguini: cooked al dente so pasta holds up when baked avoid overcooking since it softens in the oven
- Shredded mozzarella cheese: melts beautifully for stretchy cheesy layers shred your own from a block for best melt
- Grated Parmesan cheese: delivers sharp flavor and a golden top always buy real Parmesan if possible
Instructions
- Prepare the Sauce:
- Melt the butter in a large mixing bowl or gently in a microwave. Whisk in cream of chicken soup sour cream broth salt and pepper. Stir until everything is completely smooth and creamy so you will not get any lumps in the finished dish.
- Add the Chicken:
- Drop in the cooked chicken chunks and use a big spoon to stir everything together thoroughly. Make sure every piece of chicken is coated well by the sauce for even flavor throughout.
- Combine with Pasta:
- Fold in the linguini gently with tongs or a spatula. The goal is to combine without breaking the pasta. Toss until the sauce is evenly distributed and everything looks silky and glossy.
- Transfer to Baking Dish:
- Scrape the whole mixture into a glass 9 by 13 inch baking dish. Use a spatula to spread it in an even layer for uniform cooking and browning.
- Top with Cheese:
- Sprinkle shredded mozzarella all over the top then add the grated Parmesan. Try to cover all corners for plenty of cheesy coverage.
- Bake to Perfection:
- Slide the dish into a preheated 350 degree oven and bake for around 40 minutes. You want the top bubbling and golden with edges just turning crisp.
- Rest and Serve:
- Let the tetrazzini cool for 5 to 10 minutes out of the oven. This helps the sauce settle so each portion scoops out neatly and does not run.

I love the sharpness that real Parmesan brings on top. Whenever I serve this for a birthday dinner it is always the first empty dish on the table. My grandma always insisted the best part was the crispy edges.
Storage Tips
Chicken tetrazzini keeps in the fridge for up to four days. Store it tightly wrapped directly in the baking dish or transfer to smaller airtight containers. Reheat in the oven covered with foil at 325 degrees or microwave single portions with a splash of broth to keep them creamy.
Ingredient Substitutions
No linguini on hand Use spaghetti or fettuccine as they have a similar texture and work just as well. If you do not eat chicken try this recipe with turkey chunks or a mix of mushrooms for a vegetarian spin. Plain Greek yogurt stands in for sour cream if needed.
Serving Suggestions
This dish is a complete meal but I always like to add a fresh side salad tossed in a simple vinaigrette to cut the richness. Garlic bread or steamed green beans round out the meal beautifully. Top each serving with extra Parmesan or a sprinkle of parsley if you like.
Cultural and Historical Context
Tetrazzini is believed to be named after an Italian opera singer and became a classic American casserole in the early 1900s. Traditionally it is made with chicken turkey or seafood and pasta in a creamy sauce baked until bubbly. This easy version brings all of that history and flavor to modern home kitchens.
Seasonal Adaptations
Add peas or asparagus for spring flavor Fold in sautéed mushrooms in fall Swap in leftover turkey after the holidays
Success Stories
This recipe has made its way into many of my friends meal rotations because of how simple it is to customize and how reliably delicious the results are. It is the ultimate fallback when you are feeding a crowd or just want to deliver a bit of cozy nostalgia in every serving.
Freezer Meal Conversion
Let the casserole cool completely after assembling but before baking. Wrap tightly and label with the date then freeze for up to two months. To bake from frozen add about fifteen minutes to the time and check for bubbles at the edges before serving.

This casserole brings comfort and joy to every table. Try it for any occasion when you want something creamy, cheesy and deeply satisfying.
