Why you’ll love it

Chicken tetrazzini is a nostalgic pasta bake that you’ll probably remember from your childhood. It’s creamy, cheesy, and loaded with chicken and mushrooms. My three cheese version has cream cheese, parmesan, and mozzarella. It’s heavenly!

Our kitchen much prefers making chicken tetrazzini completely from scratch. It’s still pretty easy to make without condensed soup here, and we wouldn’t have it any other way for that crave-worthy homemade taste your family deserves.

What does chicken tetrazzini mean?

  • While this chicken casserole was reportedly named after the Italian opera singer Luiza Tetrazzini, this is definitely a very American dish.

What you’ll need

  • Pasta – we’re using the classic choice of spaghetti
  • Olive oil and butter – for sautéing
  • Onion and garlic – tasty aromatics. I like Vidalia (sweet) onions.
  • Chicken – two boneless/skinless chicken breasts (about a pound of them, give or take). You could use chicken thighs instead.
  • Italian seasoning – it comes in a single jar and packs a punch of concentrated herb flavor
  • Mushrooms – I use cremini, sometimes labeled as baby bellas, but white mushrooms work too
  • Chicken broth – for moisture and more savory goodness
  • Heavy cream – to make it next-level luscious
  • Cheese – our trio is cream cheese, parm, and mozza. Grate your own since it tastes and melts better.

Can I use rotisserie chicken instead?

  • For a shortcut, use 3-4 cups of cooked/rotisserie shredded chicken and add it in during step 7.
  • You could even use turkey meat if you prefer, like if you’ve got leftover Roast Turkey from Thanksgiving!

How to make chicken tetrazzini

This is an overview with step-by-step photos. Full ingredients & instructions are in the recipe card below.

sauteing chicken and mushrooms in a soup pot for chicken tetrazzini

Prep your ingredients, and cook the spaghetti for 2 minutes less than package directions. Sauté the onion, then add in the seasoned chicken. Once almost cooked, remove the chicken to a plate. Cook the mushrooms along with the garlic and Italian seasoning.

adding cream cheese to a pot to make sauce for chicken tetrazzini

Add the cream cheese, broth, and cream. Simmer while stirring until the cream cheese has melted and it thickens up a little. Return the chicken to the pot, and add in the drained spaghetti. Toss to coat everything.

Transfer it to a 9×13 baking dish, and then top with the mozzarella and parmesan. Bake at 350F for 30 minutes, and then broil for a few minutes until the cheese is nicely browned. Let it rest for a few minutes, and enjoy!

  • I prefer to grate my own parmesan cheese and always keep a block in my fridge. I use this cheese grater.
  • You’ll need a 9×13 baking dish for this recipe.
  • Easily mince the garlic with a garlic press. You don’t even have to peel the cloves beforehand.
  • I use my favorite cooking spoon for the stirring part of this recipe!

Substitutions and variations

  • I recommend sticking to spaghetti for this recipe since different types of pasta absorb liquid differently, but if you’ve only got another long pasta shape on hand (like linguine or bucatini), then you could try that.
  • Try subbing half or all of the chicken broth with dry white wine. 
  • We’ve only tested using heavy cream and the liquid ratios as listed. A substitution would likely end up with too thin of a sauce.
  • If you’re really not a mushroom fan, you could leave them out. Try peas instead of or in addition to the mushrooms.

Can I make chicken tetrazzini ahead?

  • You sure can. Follow the recipe up until the baking step, cover the baking dish tightly in foil, and freeze it for up to 3 months. When ready to bake, either let it thaw in the fridge first or bake from frozen.
  • Bake at 350F with foil loosely covering it until the broiling step. Timing will vary depending on your oven, baking dish, and whether it’s frozen or not, but 40 minutes is a good starting point. You may need to let it stand a bit longer (10+ minutes) after baking if there’s lots of excess liquid.

Leftovers and storage

  • This is one of those dishes that’s best day one. The leftovers will still be tasty but also a bit drier than when it’s first made.
  • Store in the fridge for 3-4 days in an airtight container. Reheat on a low heat in the microwave or stove until warmed through.
  • I don’t recommend freezing leftovers of creamy pasta dishes in general.

Three Cheese Chicken Tetrazzini

This chicken tetrazzini recipe from scratch has spaghetti tossed in an irresistible creamy garlic sauce, tender chicken, and three kinds of cheese! It's straightforward to make.
Prep: 15 minutes
Cook: 45 minutes
Total: 1 hour
Servings: 6

Ingredients 

  • 12 ounces uncooked spaghetti
  • 1 tablespoon olive oil
  • 3 tablespoons butter divided
  • 1/2 medium onion chopped
  • 2 uncooked chicken breasts cut into 1" pieces
  • Salt & pepper to taste
  • 4 cloves garlic minced
  • 1/4 teaspoon Italian seasoning
  • 7 ounces cremini or white mushrooms sliced
  • 3/4 cup chicken broth
  • 1 cup heavy/whipping cream
  • 8 ounces cream cheese (a block of Philly) softened
  • 1 cup freshly grated parmesan cheese
  • 1 cup shredded mozzarella cheese

Instructions 

  • Prep steps: I recommend prepping all ingredients for this recipe prior to getting started. Microwave the cream cheese for 20-30 seconds so it gets very soft (or leave it on the counter for a couple hours). Season the chicken with salt & pepper after you cut it up. Preheat oven to 350F and move the rack to the top third of the oven.
  • Boil a salted pot of water for the spaghetti, and cook it 2 minutes less than indicated on the package (it was 9 minutes for the brand I used). Once it's cooked, drain it and set it aside.
  • Meanwhile, add the oil, 1 tablespoon of the butter, and the onion to a pot over medium-high heat. Sauté the onion for 4-5 minutes or until lightly browned.
  • Add in the chicken and cook for 5-6 minutes or until it's almost cooked through (don't overcook). Transfer the chicken to a plate (don't worry if there's some onions left in the pot).
  • Add the garlic, the remaining 2 tablespoons of butter, the Italian seasoning, and the mushrooms to the pot. Cook for about 5 minutes or until the mushrooms have released their water and it's mostly cooked off.
  • Increase the heat to high and add in the chicken broth, cream, and cream cheese (I cut it into smaller pieces first). Cook for 5 minutes, stirring nearly constantly to help the cream cheese melt in. Don't cook the sauce for longer because then it will get too thick and the pasta will end up dry.
  • Turn the heat off and add the chicken back to the pot, along with the cooked and drained pasta. Give it a good stir.
  • Transfer the pot contents to a 9×13 baking dish and arrange it in an even layer. Sprinkle the top with the parmesan cheese, followed by the mozzarella.
  • Bake, uncovered, for 30 minutes and then broil for a few minutes until the top has browned a bit (watch it carefully).
  • Let it sit for about 5 minutes once you take it out of the oven. I recommend using a spatula to "cut" the pasta like you would lasagna so it's easier to eat and everyone gets some melted cheese on top of their portion.

Notes

  • You can use cooked/rotisserie chicken instead if you wish (follow the recipe as normal but skip step 4 then add 3-4 cups of the cooked chicken in step 7).
  • 12 ounces spaghetti is 3/4 of a pound (16 ounce) package.

    I would recommend adding some white wine/sherry. I used to love this growing up, and it always had white wine in it.

    1. Natasha says:

      Sure!

  2. Jamie says:

    I left out the mushrooms because my family doesn’t care for them and used an Italian cheese blend I had on hand. This was so delicious. I made it in my cast iron skillet so it was able to go straight into the oven. All 3 kids, husband and myself give it 2 thumbs up.

    1. Natasha says:

      Glad it was a hit!! 😀 Thank you!!

    4 stars
    Loved this BUT I will change it up a bit next time. Boil pasta al dente…cook chicken til brown. Put it in 9×13 mixed with pasta as recipe says with cheese on top but JUST broil til cheese starts to brown. (No need to bake for 30 min at all, it just dries up the pasta!)

  6. Sharon says:

    Can’t his recipe be made ahead?

    1. Natasha says:

      There’s a “make ahead tip” in the blog post under the “recipe notes & tips” section.

    I love Chicken tetrazzini. I have to make for 8 to 10 people tomorrow. One Question how much does it make?

    1. Natasha says:

      Hi Melanie! So, I based the recipe card nutrition info on a total of 6 servings (the nutrition info being for one portion). I basically went for a decent-sized portion vs. a smaller one, but it’s quite subjective really. I’d say it could serve up to 8 depending on what else you serve it with/how hungry people are. It’s a 9×13 pan, and it’s quite rich, so if you’ve made similar dishes before, you may be able to gauge whether you’ll need to double it using two pans (and have leftovers) or if you’re good with just the one.
