What You’ll Gather

• 2 cups cooked pasta (spaghetti or fettuccine work beautifully)
• 2 cups cooked chicken, shredded
• 1 cup cooked mushrooms, sliced
• 1 cup chicken broth
• 1 cup cream (heavy cream recommended for richness)
• 1 cup shredded mozzarella cheese
• 1/2 cup grated Parmesan cheese
• 1/2 cup chopped green onions
• 2 tablespoons olive oil
• 2 tablespoons flour
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1/2 teaspoon black pepper
• 1/2 teaspoon salt
• 1 cup turkey bacon, cooked and chopped (optional—adds a smoky crunch)

Prep & Cook Tools

• Large pot for boiling pasta
• Large skillet for cooking mushrooms and making sauce
• Measuring cups and spoons for precise ingredient measurement
• Wooden spoon or spatula for stirring
• Baking dish (9×13 inch works well)
• Oven mitts for safe handling
• Mixing bowl for combining ingredients

Stepwise Method: Baked Chicken Tetrazzini

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add 2 cups of your chosen pasta, such as spaghetti or fettuccine, and cook until al dente according to package instructions. Drain and set aside.

Step 2: Sauté the Mushrooms

Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add 1 cup of sliced cooked mushrooms and sauté until tender and slightly golden, about 5 minutes. Remove from skillet and set aside.

Step 3: Make the Creamy Sauce

In the same skillet, add the flour and stir constantly for 1-2 minutes to create a roux. Gradually whisk in the 1 cup of chicken broth and 1 cup of cream, ensuring there are no lumps. Cook over medium heat until the sauce thickens, about 5 minutes. Stir in garlic powder, onion powder, salt, and pepper.

Step 4: Combine Ingredients

In a large mixing bowl, combine the cooked pasta, shredded chicken, sautéed mushrooms, chopped green onions, and the creamy sauce. Mix well to coat everything evenly.

Step 5: Add Cheese and Turkey Bacon

Stir in 1 cup shredded mozzarella, 1/2 cup grated Parmesan, and the optional chopped turkey bacon. The turkey bacon adds a smoky, crispy contrast that’s totally delicious but feel free to skip or substitute as you like.

Step 6: Bake to Perfection

Preheat your oven to 350°F (175°C). Transfer the pasta mixture to a greased 9×13 baking dish. Sprinkle a little extra mozzarella and Parmesan on top if you like a golden crust. Bake uncovered for 25-30 minutes, or until bubbly and golden on top.

Step 7: Serve and Enjoy

Let the Baked Chicken Tetrazzini rest for 5 minutes before serving. This allows it to set slightly and makes it easier to portion. Garnish with additional chopped green onions or fresh herbs if desired.

Better-for-You Options

• Swap heavy cream for half-and-half or evaporated milk to reduce fat content without sacrificing creaminess.
• Use whole wheat or gluten-free pasta for added fiber or dietary needs.
• Replace turkey bacon with diced grilled vegetables like zucchini or bell peppers for a veggie boost.
• Opt for low-sodium chicken broth to control salt levels.

Steer Clear of These

Avoid using pre-shredded cheeses with additives that can affect melting quality. Also, steer clear of overcooking the pasta initially—it should be just al dente since it will bake further in the oven. Lastly, skip overly salty or flavored broths that can overpower the delicate balance of this dish.

Make-Ahead & Storage

This Baked Chicken Tetrazzini is a fantastic make-ahead meal. You can assemble it completely and refrigerate for up to 24 hours before baking. When ready, bake directly from the fridge—just add a few extra minutes to the baking time. Leftovers store well in an airtight container in the refrigerator for 3-4 days. Reheat gently in the oven or microwave until warmed through.

Common Questions

Can I use rotisserie chicken for this recipe?

Absolutely! Rotisserie chicken is a perfect shortcut for shredded chicken in this recipe. It adds great flavor and saves time, making your Baked Chicken Tetrazzini even easier to prepare.

What’s the best pasta to use for Tetrazzini?

Traditional Tetrazzini often uses spaghetti or linguine, but fettuccine works beautifully too. The key is to use pasta that holds sauce well and doesn’t get mushy after baking.

Can I freeze Baked Chicken Tetrazzini?

Yes! Freeze the unbaked casserole in a freezer-safe dish, tightly wrapped, for up to 3 months. Thaw overnight in the fridge before baking as directed.

How can I add more flavor to this dish?

Try stirring in fresh herbs like thyme or parsley, or a splash of white wine into the sauce. For a twist, you might love the rich creaminess found in recipes like Garlic Parmesan Chicken Alfredo Bake or the robust taste of Tuscan Garlic Chicken Pasta.
