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.

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.

Do we love it? Made it three times in one month. I particularly love the history. First developed by a chef at the Palace Hotel in San Francisco in 1905 for soprano Luisa Tetrazzini. Buon gusto!
Update: I made this with my changes and my mom loved it! She couldn’t believe that cream cheese with chicken could taste so good! It was delicious and we have plenty for leftovers for the rest of the week! I changed it up with penne pasta and oregano instead of tarragon but I think for next time, I’ll leave the sauce and the pasta separate and then, it can be combined on the plate. It would work better because it was hard to stir everything together to get it all coated. I also WILL use spaghetti next time.
Great to hear Julie, we love this recipe too.
