Why You’ll Love This Recipe
If you’re like us and always looking for new ways to serve chicken, this dish is a guaranteed hit. It’s simple, satisfying, and uses pantry staples. The cream cheese and diced tomatoes with green chilies (like Rotel) add the perfect touch of richness and spice.
Plus, since it’s made in the slow cooker, cleanup is a breeze—just one pot! You can even prep the pasta the night before to save even more time.
Can You Cook Pasta in a Slow Cooker?
Technically, yes—but for the best texture, we recommend boiling the spaghetti separately and stirring it in at the end. Because this recipe has a creamy base (not broth), cooking the pasta separately ensures it doesn’t get mushy and is cooked perfectly al dente.
Ingredients
- 3 boneless, skinless chicken breasts
- 1 (10 oz) can diced tomatoes with green chilies (like Rotel)
- 1 can cream of chicken soup
- 1 can cream of mushroom soup
- ½ onion, diced
- 2 tsp minced garlic
- 2 tsp Italian seasoning
- 4 oz cream cheese, cut into cubes
- 2 cups shredded cheddar cheese
- 1 (16 oz) package spaghetti, cooked al dente
How to Make Cheesy Chicken Spaghetti in the Crock Pot
Step 1: Add the Base Ingredients
Place the chicken breasts in the slow cooker. Add the diced tomatoes (undrained), cream of chicken soup, cream of mushroom soup, diced onion, garlic, and Italian seasoning. Cover and cook on low for 6–8 hours or high for 3–4 hours.
Step 2: Shred the Chicken
Once cooked, remove the chicken and shred it with two forks (or use a hand mixer for quick shredding). Return the shredded chicken to the slow cooker.
Step 3: Add the Cheese
Stir in the cream cheese and shredded cheddar cheese. Cover and cook on low for 20–30 minutes, or until the cheese is fully melted and combined.
Step 4: Cook and Add Pasta
While the cheese is melting, cook the spaghetti according to package directions. Drain and add it to the slow cooker. Stir everything together until the pasta is fully coated in the cheesy chicken mixture.
Serve and enjoy!

Tips & Variations

- Use Leftover Chicken: Rotisserie or cooked shredded chicken works great to speed things up.
- Add Veggies: Stir in bell peppers, mushrooms, or even frozen peas for extra color and nutrition.
- Swap for Rice: Try cooked rice (or cauliflower rice for low-carb) instead of pasta.
