How to Make Easy Chicken Tetrazzini Recipe
Step 1: Prepare Your Pasta
Begin by bringing a large pot of salted water to a boil. Add the spaghetti, broken in half for manageable bites, and cook until just al dente. This texture is key so the pasta doesn’t get mushy when baked later. Once cooked, drain the pasta and set it aside while you prepare the sauce.
Step 2: Sauté the Vegetables
In a large skillet, melt the butter and olive oil over medium heat. Toss in the diced onion and cook for 2 to 3 minutes until it softens and turns slightly translucent. Then stir in the minced garlic and sliced mushrooms. Let everything cook together for about 5 to 6 minutes until the mushrooms are tender and the mixture smells irresistible.
Step 3: Mix the Sauce and Chicken
In a big mixing bowl, combine the cooked chicken and your sautéed vegetables. Add the cream of mushroom soup, cream of chicken soup, sour cream, and chicken broth. Season with garlic powder, onion powder, salt, and pepper. Stir everything together until you have a creamy, flavorful mixture ready to embrace the pasta.
Step 4: Combine Pasta and Sauce
Fold the drained spaghetti gently into the creamy chicken and mushroom sauce. This coating ensures every strand is deliciously covered, creating a perfect balance of protein, sauce, and pasta in each bite.
Step 5: Assemble and Bake
Transfer your mixture into a greased 9×13-inch baking dish, spreading it out evenly. Sprinkle the shredded mozzarella and grated Parmesan cheese over the top, then finish with an even layer of breadcrumbs. Bake in a preheated 350°F oven for 25 to 30 minutes until the casserole bubbles and forms that gorgeous golden topping. Let it rest for 5 minutes before serving to let everything set beautifully.
How to Serve Easy Chicken Tetrazzini Recipe

Garnishes
A sprinkle of freshly chopped parsley adds a pop of color and a touch of fresh flavor that complements the rich, cheesy casserole. You can also add a little cracked black pepper or a few red pepper flakes if you like a subtle kick.
Side Dishes
Since this Easy Chicken Tetrazzini Recipe is wonderfully hearty on its own, light sides work best. Consider serving it with a crisp green salad dressed in a tangy vinaigrette or some steamed seasonal vegetables to balance out the creaminess. Garlic bread or warm dinner rolls are also excellent for scraping up every last bit.
Creative Ways to Present
For a fun twist at dinner parties, try individual ramekins or small oven-safe dishes to bake single servings. It makes each portion look extra special and keeps guests excited. You can also drizzle a bit of truffle oil on top before the breadcrumbs go on for an upscale touch that impresses.
Make Ahead and Storage
Storing Leftovers
After your family has enjoyed the first round, store leftovers in an airtight container in the refrigerator. This dish keeps well for 3 to 4 days, making it perfect for easy lunches or dinner round two.
Freezing
If you want to make this Easy Chicken Tetrazzini Recipe in advance, it freezes beautifully. Assemble the casserole but hold off on baking. Wrap tightly with foil and freeze for up to 3 months. When ready, thaw overnight in the refrigerator and bake as directed, adding a few extra minutes if needed.
Reheating
Reheat leftovers in the oven at 350°F until warmed through to keep the texture crispy on top and creamy inside. If you’re in a hurry, microwave on medium power in slices, stirring midway for even warming, but the oven method truly preserves all the delicious layers.
FAQs
Can I use other types of pasta for this recipe?
Absolutely! While spaghetti is traditional and works wonderfully in this recipe, you can swap it for linguine, fettuccine, or even penne for a slightly different texture that still absorbs the sauce beautifully.
Is it possible to add vegetables for more nutrition?
Yes! Peas, chopped spinach, or even diced bell peppers make great additions. Just stir them into the sauce mixture before baking to sneak in extra color and nutrients without compromising flavor.
Can I make this dish gluten-free?
Definitely. Use gluten-free pasta and substitute the breadcrumbs with gluten-free alternatives or crushed gluten-free crackers. Just be sure your cream soups are gluten-free or make homemade versions for peace of mind.
What’s the best way to shred the chicken quickly?
Using rotisserie chicken from the store is a fantastic shortcut. To shred cooked chicken easily at home, cool it slightly, then use two forks to pull it apart quickly into bite-sized pieces.
How can I make this recipe dairy-free?
For a dairy-free version, try swapping the butter for olive oil, use dairy-free sour cream and cheese alternatives, and opt for dairy-free cream soups or homemade substitutes. It won’t be quite the same but still delicious and comforting.
