How to Make Crockpot Chicken Spaghetti

Combine Base: Place chicken breasts, both cream soups, chicken broth, garlic, chopped onion, and optional bell pepper into the crockpot. Stir gently to combine ingredients in a creamy base.
Slow Cook: Cover crockpot and cook on low for 3–4 hours (or high 2–3), until chicken shreds easily and sauce is thickened, fragrant, and bubbling around the edges.
Shred Chicken: Remove chicken to a cutting board, shred with two forks, then return shredded chicken to the sauce. Stir well to coat every tender piece in creamy goodness.

For the Pasta and Cheese:

Add Noodles: Break spaghetti noodles in half and add them to the crockpot, pressing gently to submerge. The noodles will absorb liquids and soften, so ensure they’re evenly coated.
Stir in Cheese: Sprinkle shredded cheddar, Monterey Jack, and Parmesan over the pasta. Stir slowly until the cheeses melt completely and create a rich, gooey, comforting sauce.
Final Cook: Cover and cook on low for 30–40 minutes, stirring halfway through. Watch for noodles to become al dente and sauce to bubble up around the edges.
Rest & Serve: Uncover and let the dish rest for 5 minutes. This allows the sauce to thicken slightly and flavors to meld, for the creamiest final texture.

Optional: Top with chopped parsley or extra Parmesan for a pop of color and flavor.

Make Ahead Options

These Crockpot Chicken Spaghetti preparations are perfect for busy weeknights and can save you precious time! You can prep the chicken and sauce up to 24 hours in advance by combining chicken breasts, cream soups, broth, garlic, onion, and optional bell pepper in your crockpot. Just cover and refrigerate until you’re ready to cook. To maintain quality, it’s best to leave the spaghetti uncooked until you’re ready to serve; add it during the final cooking stage for optimal texture. When you’re ready for dinner, simply cook the mixture on low for 3–4 hours, then add the uncooked spaghetti and cheese for a comforting meal that feels homemade, even on your busiest days!

Crockpot Chicken Spaghetti Recipe FAQs

What type of chicken is best for Crockpot Chicken Spaghetti?
I recommend using boneless, skinless chicken breasts that are fresh or fully thawed. They shred beautifully after slow cooking and soak up the creamy sauce perfectly. Avoid frozen chicken, as it can release too much water and dilute the flavors.

How long can I store leftover Crockpot Chicken Spaghetti in the fridge?
Store any leftovers in an airtight container once fully cooled, and it will keep well for up to 3 to 4 days. Reheat gently on the stove or microwave, adding a splash of chicken broth to revive the creamy texture.

Can I freeze Crockpot Chicken Spaghetti, and if so, for how long?
Absolutely! This dish freezes wonderfully for up to 3 months. To freeze, portion into freezer-safe containers, leaving a little space at the top for expansion. When ready, thaw overnight in the refrigerator and gently reheat on low heat, stirring occasionally and adding a bit of broth if it feels too thick.

What should I do if my Crockpot Chicken Spaghetti turns out too watery?
No worries! If you notice it’s too watery after cooking, simply uncover the crockpot and let it cook on high for an additional 15-20 minutes to reduce excess liquid. Stir occasionally to help the sauce thicken, or add a small amount of shredded cheese to help absorb moisture.

Is Crockpot Chicken Spaghetti safe for pets or suitable for common allergies?
This recipe contains dairy and wheat, which can be problematic for some pets and people with allergies. Keep in mind that ingredients like cream soups and cheeses are not recommended for dogs or cats. For gluten-free or dairy-free options, you might try substituting gluten-free pasta and dairy-free cheese alternatives, but those adjustments will change the classic taste and texture.
