Comfort food at its finest! Slow Cooker Chicken Tetrazzini has tender shredded chicken in a creamy sauce with mushrooms. A one pot meal the entire family will love.

Having dinner together with my family is most important to me. We try as much as possible to eat dinner at the table, so finding a meal we all love makes dinner time run smoother (remember I have a very picky 13-year old).

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.

Recipe Ingredients

chicken breasts, mushrooms, onion, broth and seasonings.
  • 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.
  • Chicken Broth: A touch of chicken broth is added to the sauce base.
  • 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: 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.

Step-by-Step Directions

Step One – I start by adding the chicken, seasonings, mushrooms, and onions to the slow cooker. I let that cook all day.

Step Two – When I am ready to serve dinner,  I add cream cheese, shred the chicken then stir in a half-pound of cooked spaghetti.

Step Three – Add a bit of mozzarella and cover the slow cooker until the cheese melts.

Recipe FAQs

Can I lower the fat in this dish?

This meal is great with 1/3 less fat cream cheese and reduced-fat mozzarella cheese, make it to accommodate your family’s diet!

Can I use turkey?

Yes, if you can find a small turkey breast or turkey tenderloin, that would work great in this recipe.

Can a rotisserie chicken be used?

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.

Slow Cooker Chicken Tetrazzini

What I love about this crock pot chicken tetrazzini is that it’s great for spaghetti night, but a fresher spin on pasta.

      How can we adjust the recipe if we only have a 4.5 quart slow cooker??

        Looking back at the photos, I think it will fit in a 4.5 quart. I used a 6 quart and it seems the slow cooker is only half full.

      Just tried this last night and it turned out great. Took your reasoning that my slow cooker runs hot and altered accordingly. Thanks.

      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.

      I added garlic and Mongolian hot sauce, and you can’t go wrong with more cheese!

      My family loved this and it was requested again by my soon to be sister in law, I actually just chucked the pasta in and left it half an hour at the end of the cook, (admittedly was a little long and was a bit mushy, next time I’ll only leave it in for twenty minutes and check it after fifteen). Thank you.

      Delicious! I left out the mushrooms and used Italian seasoning instead of tarragon. So so good. Making again today for my mom’s birthday supper. Crockpot makes the best chicken and I use it even if i’m home all day (like roast).

      I made as directed and really wanted to like it, but all that cream cheese just ruined it for me. The cream cheese in the sauce was just too intense.
