Ingredients You Will Need

The beauty of this recipe lies in its sheer simplicity. To get that perfect creamy, cheesy bite, you will need:

• 12 ounces spaghetti, broken in half
• 2 cups cooked, shredded or diced chicken
• 3 tablespoons butter
• 8 ounces mushrooms, sliced
• 3 cloves garlic, minced
• 3 tablespoons all-purpose flour
• 2 cups chicken broth

• 1/2 cup dry sherry or white wine (optional)
• 1 cup grated Parmesan cheese
• 1 cup shredded mozzarella cheese
• Fresh parsley, chopped, for garnish
• Salt and black pepper, to taste

Step-by-Step Instructions for The Best Chicken Tetrazzini

Follow these easy steps. I’ve broken them down into quick, bite-sized pieces so you can achieve maximum comfort-food flavor without any stress.

Step 1: Cook the Pasta Preheat your oven to 375°F (190°C). Bring a large pot of salted water to a boil. Cook the spaghetti until just al dente, then drain and set aside.

Step 2: Sauté the Mushrooms Melt the butter in a large skillet over medium heat. Add the mushrooms and cook for 5 to 6 minutes until browned. Add the garlic and cook for 30 seconds until fragrant.

Step 3: Build the Sauce Sprinkle the flour over the mushrooms and stir for 1 minute. Slowly pour in the chicken broth, heavy cream, and sherry if using, whisking constantly until smooth. Simmer for 5 minutes until thickened.

Step 4: Combine Everything Stir in half of the Parmesan cheese, along with the cooked chicken and drained spaghetti. Season with salt and pepper, then transfer everything to a greased baking dish.

Step 5: Top and Bake Sprinkle the remaining Parmesan and mozzarella evenly over the top. Bake for 20 to 25 minutes, or until bubbling and golden. Garnish with fresh parsley before serving.

Pro Tips for the Ultimate Tetrazzini

Small adjustments can take your chicken tetrazzini from good to absolute perfection.

Don’t overcook the pasta: Cooking the spaghetti just shy of al dente helps prevent it from turning mushy once it finishes baking in the sauce.

Brown the mushrooms properly: Letting the mushrooms develop a deep golden color before adding the garlic builds significant flavor into the finished dish.

Use freshly grated cheese: Pre-shredded cheese often contains anti-clumping agents that can prevent the topping from melting as smoothly and evenly.

Let the sauce thicken fully before combining: Rushing this step can leave the finished bake watery, so give the sauce enough time on the stovetop to reach a nicely coating consistency before mixing in the pasta and chicken.

What to Serve with Chicken Tetrazzini

This rich, comforting dish pairs well with a variety of simple sides.

As a main course: Serve alongside a simple green salad with a light vinaigrette to balance out the richness of the cream sauce.

With garlic bread: A warm, crusty slice of garlic bread is perfect for scooping up any extra sauce left on the plate.

Family style: Bring the whole baking dish straight to the table and let everyone serve themselves for an easy, comforting family dinner.

With steamed vegetables: A side of steamed broccoli or green beans adds a fresh, simple contrast to the richness of the pasta bake.

How to Store Chicken Tetrazzini

Have leftovers? It is incredibly easy to save for later.

In the Fridge: Store the completely cooled tetrazzini in an airtight container for up to 4 days.

How to Reheat: Reheat individual portions in a 350°F oven for 10 to 15 minutes, or in the microwave with a splash of milk to loosen the sauce.

In the Freezer: You can freeze the baked, cooled casserole in a freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating.

Frequently Asked Questions

Can I use rotisserie chicken? Absolutely. Shredded rotisserie chicken saves time and adds great flavor, making this an even quicker weeknight meal.

Can I make this without the sherry or wine? Yes, you can simply omit it and use a bit of extra chicken broth in its place, though the wine does add a subtle depth of flavor to the finished sauce.

Can I prep this ahead of time? Yes! You can assemble the entire dish up to a day in advance and store it covered in the fridge. When you are ready to bake, just add a few extra minutes to the baking time since it will be starting from cold.
