What is Chicken Tetrazzini Made Of?

Spaghetti – Spaghetti noodles are the traditional pasta for this dish but feel free to use any pasta noodle shape you have on hand. Be sure to cook the pasta al dente so it doesn’t get too mushy after baking.

Chicken – This recipe starts with cooked chicken. So prep the chicken or for an easier meal prep use a rotisserie chicken from the store.

Aromatics – Use onion, celery, green bell pepper to create a delicious flavor base to the sauce.

Spices – Minced garlic and salt and pepper to taste. Fresh parsley for garnishing.

Cream Soup – I use cream of chicken soup, along with the tomato sauce. Feel free to double up on the cream soups and leave out the marinara sauce all together.

Cream – Use heavy cream and not half & half or milk for a richer flavor.

Cheese – I used shredded Colby Jack but use your favorite. Shredding/grating your own cheese from a block for better melting.

Breadcrumbs – I like to use Italian seasoned crumbs but use your favorite. You can even use Panko or cracker crumbs.

How To Make Creamy Chicken Tetrazzini

ONE: Cook the noodles al dente, according to package directions. Reserve a little of the pasta cooking water for later. Preheat the oven to 350° and spray a 9×13 inch pan with cooking spray.

TWO: Melt half the butter in a large pan and cook the onions and garlic for 4 minutes. Add the salt, pepper, celery and bell pepper and cook for another 2 minutes. Stir in the mushrooms and cook for an additional 4 minutes.

THREE: Add in the spaghetti sauce, cream of chicken soup, heavy cream, and the cream cheese. Stir until combined.

FOUR: Pour the sauce over the noodles and toss till combined. If you want the casserole a little saucier, add a little bit of the spaghetti water.

FIVE: Spread the coated spaghetti out in the prepared baking dish and sprinkle with the cheese.

SIX: Melt the remaining butter. Stir the bread crumbs into the melted butter until combined. Sprinkle the top of the cheese with the breadcrumbs.

SEVEN: Place the pan in the oven and bake for 30 minutes, or until the casserole is bubbly and the topping is a light golden brown. Remove and serve with your favorite side dish.

What is the difference between Tetrazzini and Alfredo?

Tetrazzini is a baked pasta casserole usually made with mushroom and chicken sometimes, another protein enveloped in a cream-based sauce.

Alfredo, on the other hand, is a sauce that is an emulsion of butter, garlic, and parmesan cheese that coats pasta.

Why is it called Chicken Tetrazzini?

Chicken tetrazzini is named after the Italian opera singer Luisa Tetrazzini but originated in America. The recipe is a baked chicken and pasta dish smothered in a creamy sauce, often made with earthy mushrooms or sweet peas.

After the initial cooking, finish the casserole with either a layer of breadcrumbs, melted cheese, or a combination of both.

What does Tetrazzini mean in English?

Tetrazzini means a pasta dish made with a cream sauce and mushrooms.

What type of pasta goes in Tetrazzini?

Traditionally, long-strand pasta such as spaghetti, linguine, or vermicelli are the preferred shape in this dish.

However, feel free to use short kinds of pasta like macaroni, ziti, penne, rigatoni, or spirals while avoiding tiny pasta such as orzo or Ditalini as they are too small for the casserole.

What can I substitute for the cream of chicken soup?

Feel free to swap cream of mushroom for the cream of chicken soup without effecting the flavor of the dish.

How to Store and Freeze Tetrazzini:

Store any leftovers in an airtight container in the fridge for up to 5 days.

To freeze, prepare the recipe as written in a freezer safe dish. Cover tightly in plastic wrap and then cover with foil and freeze for up to 2 months.

When ready to bake, thaw overnight in the fridge and then bake accordingly.

Can I make Chicken Tetrazzini ahead of time?

Of course! This is a wonderful make-ahead dish.

Make according to recipe instructions, but instead of baking, cover the casserole tightly with foil and refrigerate for up to 24 hours.

When ready to enjoy, remove from fridge, bake according to recipe adding about 15 minutes onto the baking time.

Can I make this in the slow cooker?

Yes, you can make this recipe in a crock pot or slow cooker. It’s perfect for a busy day.

  • Add all the ingredients (minus the cream cheese, pasta, and cheese) and cook on low for 4 hours.
  • Cube and stir in the cream cheese, cover and let cook while you prepare the pasta noodles.
  • Cook the pasta al dente, drain, and add to the slow cooker. Stir to combine.
  • Top with cheese and breadcrumbs and continue to cook for 10 more minutes or until cheese is melty.
  • Serve with garlic bread and enjoy!

What to Serve with Tetrazzini

Serve with a simple side salad and my easy garlic knots for a complete hearty and comforting meal!

Tips for No Leftovers

  • You can cook the chicken before using in the recipe or for easier prep, use a rotisserie chicken from the deli. I like to keep cooked chicken breasts in the freezer for just this purpose.
  • I prefer shredded chicken in this dish but cubed works well too.
  • Cook the pasta “al dente” or firm to the bite. The noodles will cook even more when baked and if you over cook the pasta in the beginning it will be mushy after its baked.
  • You can cook the pasta ahead of time, drain, and store in the refrigerator until ready to use.
  • If the sauce seems too thick, thin it out with some of the pasta cooking water. Or you can use chicken stock or broth.
  • Do not cover the casserole when baking as you want the crumb topping to turn golden brown and crispy. If it starts to get too brown, cover with foil towards the end of the baking time.
