How To Make Crock Pot Chicken Tetrazzini

- Add cream cheese: Cut cream cheese into cubes and add to the slow cooker. Cover to allow it to melt.
- Cook the pasta: While the cream cheese is melting, cook spaghetti noodles according to package directions until al dente.
- Shred chicken and combine: Shred the chicken with two forks in the slow cooker. Stir to combine with the sauce.

Recipe Tips
- Can I use turkey instead of chicken? Yes, turkey breast or tenderloin works well in this recipe.
- Why not use rotisserie chicken? Raw chicken cooks with the broth to build more flavor into the dish.
- How to keep the noodles firm: Cook them al dente before adding to avoid mushy texture.
- Can I make this lighter? Use ⅓ less fat cream cheese and reduced-fat mozzarella.
- Do I need to shred the chicken separately? No, you can shred it right in the slow cooker with two forks.
