- 1 can cream of chicken soup
- 1 can cream of mushroom soup
- ½ onion, diced
- 2 teaspoons minced garlic

How to Make Crock Pot Cheesy Chicken Spaghetti
Step 1: Add Ingredients to the Slow Cooker
Place the chicken breasts in your crock pot. Add the diced tomatoes (with juice), 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 until the chicken is tender.
Step 2: Shred the Chicken
Once the chicken is fully cooked, remove it from the slow cooker and shred it using two forks (or a hand mixer for quicker shredding). Return the shredded chicken to the slow cooker.
Step 3: Add Cheeses
Stir in the cubed cream cheese and shredded cheddar. Cover again and cook on low for another 20–30 minutes, until the cheese is melted and the sauce is creamy and well combined.
Step 4: Cook the Pasta
While the cheese melts, cook the spaghetti according to package directions until al dente. Drain and stir the cooked noodles into the cheesy chicken mixture in the slow cooker.
Step 5: Serve and Enjoy
Dish it up hot and creamy! This cheesy chicken spaghetti is comfort food at its best.
Can You Cook Pasta in the Crock Pot?
You can cook pasta in the slow cooker, but for this creamy recipe, it’s best to cook the spaghetti separately. Cream-based sauces don’t always hydrate pasta evenly in the slow cooker, so boiling the pasta first helps keep the texture perfect and prevents it from becoming mushy.
What to Serve with Cheesy Chicken Spaghetti
- Fresh Salad – A simple green salad with vinaigrette helps balance the richness of the pasta.
- Roasted Veggies – Try steamed broccoli or roasted green beans for an easy side.
- Dinner Rolls or Bread – Perfect for soaking up that cheesy sauce!
Tips for Success
- Spray the crock pot with nonstick spray for easier cleanup.
- Shred chicken easily with a hand or stand mixer—so fast!
- Make pasta ahead to save time during dinner prep.
- Use leftover or rotisserie chicken to speed things up.
Easy Variations
- Swap the cheese – Try Velveeta, Monterey Jack, or even Pepper Jack for a different flavor twist.
- Change the meat – Use chicken thighs, tenders, or leftover grilled chicken.
- Try a different pasta – Penne, rotini, or elbow macaroni all work well.
- Use rice instead – For a twist, serve the creamy chicken mixture over white rice or even cauliflower rice for a low-carb option.
- Add veggies – Bell peppers, mushrooms, or spinach can be added with the onion for more color and nutrients.
How to Store and Reheat Leftovers
Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in the microwave in 30-second intervals, stirring in between, until warmed through.
Can You Freeze Chicken Spaghetti?
Yes! You can freeze it cooked or uncooked.
- To freeze before cooking: Add all ingredients (except pasta and cheese) to a freezer bag. Thaw before cooking in the crock pot.
- To freeze after cooking: Portion cooled leftovers into freezer-safe containers and freeze for up to 3 months.
My Favorite Slow Cooker
A programmable slow cooker is ideal for this recipe! It automatically switches to “warm” when the cooking time is done—perfect for keeping dinner hot without overcooking.
