How to Make Easy Chicken Tetrazzini Recipe
Step 1: Prepare Your Base
Start by preheating your oven to 350 degrees Fahrenheit (175 degrees Celsius). In a large skillet over medium heat, melt the butter until bubbly and fragrant. Add the finely chopped onion, cooking for about three minutes until it’s soft and translucent. This step builds the flavor foundation that makes your sauce comforting and inviting.
Step 2: Build Aroma and Flavor
Next, stir in the minced garlic and chopped mushrooms if you’re using them. Cook these together for another two to three minutes, allowing the garlic to release its fragrant oils and the mushrooms to soften gently. This combination adds a savory, aromatic layer to the dish that makes every bite more satisfying.
Step 3: Make the Creamy Sauce
Sprinkle the flour over the softened vegetables and stir constantly for one to two minutes to create a roux. This mixture will thicken your sauce beautifully. Slowly pour in the chicken broth, whole milk, and heavy cream while whisking continuously. Bring this to a simmer and allow it to cook for about five minutes until the sauce thickens just right—smooth and velvety with a hint of richness.
Step 4: Combine the Ingredients
Season the sauce with salt, black pepper, and garlic powder to taste. Then fold in the tender shredded chicken, sweet peas, and cooked spaghetti, ensuring everything is evenly coated with the luscious sauce. Stir in one cup of mozzarella cheese and a quarter cup of Parmesan to bind everything together and amp up the cheesiness.
Step 5: Assemble and Bake
Transfer the creamy mixture to a greased 9×13-inch baking dish. Sprinkle the remaining mozzarella and Parmesan over the top, then sprinkle breadcrumbs if you want a golden, crunchy crust. Pop the dish into your preheated oven and bake uncovered for 25 to 30 minutes until it is bubbly and the top is deliciously golden brown. Let it cool for a few minutes before serving so the flavors can settle.
How to Serve Easy Chicken Tetrazzini Recipe

Garnishes
A sprinkle of freshly chopped parsley or basil adds a pop of color and fresh flavor that contrasts nicely with the creamy pasta. You can also add a few red pepper flakes for a subtle kick if you like a little heat. These simple garnishes make the dish feel special and inviting at the table.
Side Dishes
Pair this Easy Chicken Tetrazzini Recipe with a crisp green salad dressed in a tangy vinaigrette, or some roasted vegetables like broccoli or asparagus to add texture and balance to your meal. A crusty piece of garlic bread is always a winner for sopping up every last bit of sauce.
Creative Ways to Present
For a unique twist, serve small individual portions in ramekins and bake until bubbly. Or layer the tetrazzini in a clear baking dish so guests can admire the cheesy, creamy layers before digging in. Whether family-style or plated, this dish is sure to impress and satisfy.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover leftover chicken tetrazzini tightly with plastic wrap or store in an airtight container. It will keep well in the refrigerator for up to four days, making it perfect for easy weekday lunches or dinners.
Freezing
If you want to batch cook, this Easy Chicken Tetrazzini Recipe freezes beautifully. Portion it into freezer-safe containers and freeze for up to two months. Thaw overnight in the fridge before reheating for best texture.
Reheating
Reheat leftovers in the oven at 350 degrees Fahrenheit until warmed through to keep the crispy topping intact. You can also microwave individual servings; just cover with a microwave-safe lid and heat in short bursts to avoid drying out the creamy sauce.
FAQs
Can I use other types of pasta instead of spaghetti?
Absolutely! While spaghetti is traditional, you can swap in linguine, fettuccine, or even penne. Just make sure to cook the pasta al dente to avoid it getting too mushy when baked.
Is it possible to make this dish vegetarian?
Yes, to make a vegetarian version, simply omit the chicken and increase the mushrooms or add other veggies like zucchini or bell peppers. Using vegetable broth in place of chicken broth will keep things flavorful.
How spicy is this recipe?
This Easy Chicken Tetrazzini Recipe is mild and family-friendly by default. If you prefer, you can add red pepper flakes or a dash of hot sauce to bring some heat to the creamy, cheesy comfort.
Can I use cooked chicken from a rotisserie?
Definitely! Rotisserie chicken is a great shortcut that saves time and adds wonderful flavor, making this dish even easier without compromising taste.
What can I substitute for heavy cream?
You can lighten up the recipe by replacing heavy cream with extra milk or a milk and Greek yogurt mixture. The sauce will be less rich but still creamy and delicious.

This Easy Chicken Tetrazzini Recipe feels like a warm hug on a plate—creamy, cheesy, and packed with flavors that bring everyone to the table happily.
