This recipe is not a dump and go, but it’s still pretty darn simple and worth the effort. Especially when the entire family ate it, even the 2 year old. Thanks for sharing! Printing for my family recipe binder.

This recipe uses cream cheese and chicken broth as the base, you won’t find any condensed cream of chicken soup (or mushroom soup) in this meal. What I love about this crock pot chicken tetrazzini is that it’s great for spaghetti night, but a fresher spin on pasta.
Key Ingredients
Chicken: Use boneless skinless chicken breasts.
Cream Cheese: Often, cream cheese is used in slow cooker recipes to create a thick sauce without having to use flour and butter.
Vegetables: Sliced mushrooms and diced white onion are classic vegetables for chicken tetrazzini.
Seasonings: Salt, pepper, dried tarragon, and garlic powder will season the chicken and noodles perfectly.
Cheese: Melty shredded mozzarella cheese is used (can use parmesan cheese too).
Spaghetti Noodles: You can use a different noodle than spaghetti noodles, but I strongly recommend the spaghetti noodle for it soaks up the sauce perfectly.
How to Make Slow Cooker Chicken Tetrazzini
- Cook the chicken with the mushrooms, onion, broth, and seasonings until tender.
- Stir in the cream cheese and shred the chicken to create the creamy tetrazzini sauce.
- Toss with cooked spaghetti, sprinkle over the mozzarella, and let it melt before serving.
My Recipe Tips
Here are a few tips to help you get the best results from your Crockpot Chicken Tetrazzini:
- Cook the noodles only to al dente so they don’t become mush in the dish.
- Don’t waste another dish; shred the chicken with two forks right in the slow cooker; you don’t need to shred too much, for it will fall apart more when the pasta is stirred in.
- Side dishes that go best are a green salad and garlic bread.
- Store in the fridge for up to three days or freeze for up to three months.
Recipe FAQs
This meal is great with 1/3 less fat cream cheese and reduced-fat mozzarella cheese, make it to accommodate your family’s diet!
Yes, if you can find a small turkey breast or turkey tenderloin, that would work great in this recipe.
For this recipe, raw chicken is best for it lets off some natural juices into the sauce. If a rotisserie chicken is used, you may find you need to add broth.

This recipe is delicious! I cooked it on high for 4 hours and it was just right. Also added a bit of red chili flakes and substituted the tarragon with basil and oregano. So good! Definitely a make again!
Made this today, delicious. I did use a splash more chicken broth and an additional 1/2 blk of cream cheese. I also added a little more salt and season salt to taste b/c I do agree with above it was slightly bland initially. Could do Mrs.Dash for those that need to limit sodium and a low sodium or no sodium ckn broth. Anyway, it was warm, tasty and both my 8 yr old and 18 mo old ate it up. Happy and full kids = happy mommy. Thanks for another great recipe.
Sarah, I have a question…when you cut a recipe in half, do you reduce the cooking time? It is just me and my husband. We do eat leftovers, but do not want to eat them for days. Also, can you please make note of which recipes are good to freeze and I can make the entire recipe.
I would reduce it a bit.
Good, but definitely needs more seasoning. I bet an herb cream cheese would be great instead of plain. Will make again!
Sounds great. I’m reducing the amount of mushrooms and tarragon as my family is no a fan but making it today.
I will definitely have to try this one! I’ve made turkey tetrazzini with leftover turkey but never in the slow cooker. Thanks for the recipe!
Made this last night, but used half a tablespoon of minced garlic instead of garlic powder. It’s perfect paired with an unoaked chardonnay.
Just made this chicken tetrazzini recipe. Cut the breasts in smaller pieces-cooked on high in 4 hrs. Delicious!
I LOVE chicken tetrazzini and this recipe looks delish! Cooking it in the slow cooker is such a great idea. What a time saver on busy nights!
Whilst this recipe sounds delicious, why would you want to use that amount of electricity cooking chicken for 8 hours? It would
be be much quicker and cheaper to cook the chicken in the broth on the hob in less than one eight of the time. I like your recipes but this one is a waste of time and money.
The Crock pot takes very little energy. Recipes like this are great for people who aren’t home all day, get home and dinner is ready. Cook the chicken for less time if you want!
Sarah…you were so kind to June….’whilst’ the comment may have been constructive in her eyes…it smarted a tad. One should always be capable and willing to open ones mind to another’s needs, no? Perhaps there are no crocs where June lives? Wish her well regardless…and yes, this IS a terrific idea!
We leave it and go to work!! It is awesome
Whilst June Bechley finds this recipe a waste of time and money, I think this is one of those meals a family looks forward to coming home to at the end of the day!
