When you bake this pasta casserole, some of the sauce bakes into the pasta, the flavors marry and [!!BAM!!] something wonderful happens. You’ll know what I mean when you try it. Ridiculously good, easy to prepare, kid friendly, reheats well and freezer safe. P.S. you can further simplify this by using rotisserie chicken – You’re welcome ‘ma friends :).
Chicken Tetrazzini Recipe
This recipe can be done entirely using a dutch oven so it can go from the stove to the oven saving you some dishes. You can also bake it in a 13×9″ casserole dish, but whichever path you choose, the result will be a cheesy, creamy chicken pasta bake that will have your family refilling their bowls.

Ingredients for Chicken Tetrazzini:
- We used thin spaghetti, but you can substitute with any kind of noodles you have on hand such as linguine or fettuccini pasta for your chicken tetrazzini casserole.
- SHORTCUT: (what you will see in the video), you can use a rotisserie chicken and cut away enough chicken meat to get 4 cups of shredded chicken. Light or dark meat will work.
- This recipe calls for low sodium chicken broth. Regular chicken broth is ok, but go easy on the salt and add more to taste when making the sauce.
How to Make Chicken Tetrazzini (Watch the Video below):
1. Preheat Oven to 350˚F. Cook pasta in salted water according to package instructions then rinse to stop the cooking process, drain and set aside.
2. Shred 4 cups of rotisserie Chicken into bite-sized pieces and set aside.
OR: If cooking your own chicken, In a large dutch oven pot, melt 1 Tbsp butter and 1 Tbsp oil over medium-high heat. Season chicken breasts with about 1/2 tsp salt and 1/4 tsp pepper. Once oil is hot, saute chicken until golden brown on both sides and cooked through (about 4 min per side). Remove to a cutting board to cool then dice chicken into bite-sized pieces.
3. In your large dutch oven pot, add 2 Tbsp oil then sliced mushrooms and sauté 3 min or until soft. Add diced onions and cook until onions are soft (5-7 min). Add minced garlic and sauté another 1-2 min. Transfer to a separate dish.
4. In the same pot, melt 4 Tbsp butter and add 1/3 cup flour whisking until lightly golden (1 1/2 min). Add 2 1/2 cups chicken broth, 1 Tbsp lemon juice, 1 tsp salt, 1/4 tsp pepper and whisk until smooth. Add 1 1/2 cups half and half and bring to a simmer then season sauce to taste.
5. Return chicken, mushrooms and pasta to the pot then season to taste with salt and pepper, sprinkle in 1/4 cup chopped fresh parsley and stir to combine. Sprinkle the top generously with shredded mozzarella, cover and bake at 350˚F for 30 min then remove lid and continue baking 15 min. (See notes below for 13×9 casserole dish baking tips).

Serve right away to the line that has formed behind you :). I can’t help but pair this with crunchy baby dill pickles (mildly obsessed pickle fan over here). I hope your family LOVES this!
Natasha, you rock – your sauces are always winner. Made it with ground chicken and peas – s’all I had in fridge/freezer instead of chick breasts and mushrooms and it came out like nobody’s business! Thanks.

Made this last night for dinner and it was so delicious 😋 Had some leftovers for lunch today! Thank you for another great recipe. 😉
Anna, thank you for the nice review and you are welcome 😁.
Oh yea, this looks good. Hearty and delicious, just perfect for winter. And the Chicken and Mushroom Casserole doesn’t look half bad either! You really can’t go wrong when using those two ingredients in a dish.
Kate, I agree 😀. It tastes as good as it looks.
Tetrazzini! Even the name sounds delicious. I have to make this sometime soon. Looks so comforting, Natasha.
I know, I think tetrazzini and I see myself curling up with a bowl of something creamy and pasta-y. 🙂 Thanks Coco 🙂
It is so yummy! Thank you, Natasha!:)
You are welcome Elvina, I’m glad you liked it 😁.

Natasha, you are doing such a great job, I love, love your site, I seriously check it everyday to see what you post, and I’m so excited every time. I cooked and baked so many recipes. Thank you.
Tanya, thank you so much for such a nice review and a sweet comment 😊. You are very welcome.
Really good chicken and sauce. I’m avoiding carbs so I made this with spaghetti squash. I had to bake it longer because of the extra water from the squash, but that’s my problem. The flavor was great!
Did I hear you say BAM!? Lol
lol. Yes, but it was more of a !!BAM!!. That’s great to know it works with spaghetti squash! Brilliant! Did you do anything differently when preparing it with the squash?
I just split the squash in half, salt and peppered the flesh and baked it cut side down for about 40 minutes. The rest was your recipe as written.
can i use beef with this
Hi Liza, I haven’t tried it but I imagine it could work well with ground beef. Let me know how you like it if you try it 🙂
Made it yesterday. Came out sooo good! We ate some yesterday and the rest today. Reheats perfectly (I added a little half and half)
Galina, thank you for such a great review on the recipe and I’m so happy that everyone loved it 😁.
I love how simple and satisfying this dish is! My husband is crazy about pasta, so now I know how to treat him tonight! 🙂
Tania, thank you 😁. I hope he’ll love it!
Decided to make this once the little one fell asleep and my pregnancy cravings are satisfied! So delicious! Will be making this again!!!
Tanya, thank you for such a nice review, I’m so happy you love it 😁.
Mmmmmmmmmmmmmmmmmmmmm!!!!!
My mouth is watering right now!! 🙂
LaTrice, this recipe is known to do that 😁.
Looks Delish!! I want to make it with Rossetti chicken so when should i add it in?
Nevermind got it. Cant wait to try it tonight!! 🙂
I hope you LOVE it! 🙂
Just made this, waiting for it to finish in the oven and it smells SOOOO good! It makes a lot so I think I’m gonna be freezing quite a bit for next week.
It reheats really well. We enjoyed this pot for a few days. I hope you LOVE it! 🙂
Big hit! As all your recipes are in this house lol! Even picky baby #1 ate it! (Baby #2 eats anything he can lol)
Lol, thank you so much for the nice review Irina .😀
I love that you made this is a dutch oven! Everything tastes better from a dutch oven!
I use if for everything I can. I love my dutch oven! 🙂
This looks sooo tasty. Comforting carbs mmmm!
That’s why I love pasta so much. Those tasty carbs. #worthit lol.
Can I make this to freeze? Do I bake it later if I end up freezing it? Let me know! Can’t wait to try!
Yes that will work fine. You can freeze it in oven-safe pans like you would a lasagna and freeze before baking or you can freeze cooked portions then thaw and reheat for a quick meal.
Wow! This is so incredible! Just made it and it’s So full of flavor. Delicious meal. This meal reminds of chicken Alfredo except I like this a lot more. Thank you so much for this recipe! Now I know what to make for my husbands birthday party. Everyone will love this ! I used the casserole dish and added mozzarella and some cheddar cheese. Love it.
