Step-by-Step Cooking Instructions

Now, let’s walk through how to make this delicious and easy Chicken Tetrazzini recipe step by step.

1. Cook the Pasta:

Boil the Spaghetti: Cook the spaghetti (or pasta of your choice) according to the package directions in salted water until al dente. Drain and set aside.

2. Cook the Mushrooms and Onions:

Sauté the Vegetables: In a large skillet, melt 2 tablespoons of butter over medium heat. Add the sliced mushrooms and cook until browned and tender, about 5 minutes. Add the chopped onion and garlic, cooking until softened, another 3 minutes. Season with a pinch of salt and pepper, then set aside.

3. Make the Sauce:

Start the Roux: In the same skillet, melt the remaining 2 tablespoons of butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, until the flour is lightly browned (this is called a roux).
Add the Broth and Milk: Gradually whisk in the chicken broth, followed by the milk and heavy cream, stirring constantly to prevent lumps. Bring the mixture to a simmer and let it thicken for 3-5 minutes.
Stir in Cheese: Once the sauce has thickened, stir in ½ cup of the Parmesan cheese, salt, and pepper to taste. If using white wine, add it in at this point. You can also stir in any optional add-ins like cream cheese for an even richer sauce.

4. Combine the Ingredients:

Mix Together: In a large bowl, combine the cooked chicken, sautéed mushrooms and onions, cooked pasta, and the sauce. Toss everything together until the pasta is well coated and everything is evenly distributed.

5. Assemble the Casserole:

Transfer to a Baking Dish: Pour the pasta mixture into a greased 9x13-inch baking dish, spreading it out evenly.
Add the Topping: Sprinkle the top with the remaining ½ cup of Parmesan, 1 cup of shredded mozzarella, and breadcrumbs (if using) for a crispy, golden top.

6. Bake:

Bake Until Golden: Preheat the oven to 350°F. Bake the Chicken Tetrazzini for 25-30 minutes, or until the top is bubbly and golden brown. If you want an extra crispy top, broil for 1-2 minutes at the end, keeping a close eye to avoid burning.

7. Serve:

Garnish and Serve: Once baked, remove the casserole from the oven and let it rest for a few minutes before serving. Garnish with chopped parsley for a burst of color and freshness.

How to Cook Chicken Tetrazzini: A Step-by-Step Guide

Prepare the Ingredients: Have all your ingredients ready—chicken cooked and shredded, pasta cooked, and mushrooms sautéed.
Make the Sauce: Whisk together a simple, creamy sauce using butter, flour, chicken broth, milk, and cheese.
Mix Everything Together: Combine the chicken, pasta, and sauce, making sure everything is evenly coated.
Bake Until Golden: Top with extra cheese and bake until it’s bubbly and golden brown on top.

Common Mistakes to Avoid

Overcooking the Pasta: Be sure to cook the pasta al dente, as it will continue to cook slightly in the oven. Overcooked pasta can become mushy.
Skipping the Cheese: Parmesan and mozzarella add flavor and richness to the dish, so don’t skimp on the cheese!
Not Thickening the Sauce: If your sauce isn’t thick enough, it may make the dish watery. Be sure to cook the roux properly and let the sauce simmer until it reaches the desired thickness.
Forgetting the Broil: For a crispy, golden-brown top, don’t forget to broil the casserole for a couple of minutes at the end.

Serving and Presentation Tips

Serve with a Side Salad: A light, fresh salad with a tangy vinaigrette pairs perfectly with the creamy richness of Chicken Tetrazzini.
Add Garlic Bread: Garlic bread or warm, crusty bread is great for soaking up the creamy sauce.
Family-Style Serving: Serve the casserole in the baking dish, allowing guests to help themselves for a more casual, family-style meal.
