It was one of those evenings when I opened my refrigerator and found myself staring at leftover chicken, a box of spaghetti, and not much energy to stand over the stove. That’s when I remembered my grandmother’s trick: let the crockpot do the work. Within minutes, I had everything assembled, and by dinnertime, my kitchen smelled like pure comfort food heaven. Creamy crockpot chicken spaghetti became my answer to busy weeknights when I needed something hearty, satisfying, and absolutely foolproof.
This dish combines tender chicken, perfectly cooked pasta, and a rich, creamy sauce that brings everything together. It’s the kind of meal that makes everyone ask for seconds, and the best part? You barely lift a finger. If you’re looking for more comforting one-pot meals, you’ll love my easy chicken and rice casserole that uses similar simple techniques. Let’s get started.

Ingredients You’ll Need
- 3 cups cooked chicken, shredded or cubed
- 12 oz spaghetti, broken in half
- 1 can (10.5 oz) cream of chicken soup
- 1 can (10.5 oz) cream of mushroom soup
- 2 cups chicken broth
- 1 cup sour cream
- 2 cups shredded cheddar cheese, divided
- 1 small onion, finely diced
- 1 red bell pepper, diced
- 2 cloves garlic, minced
- 1 tsp Italian seasoning
- Salt and black pepper to taste
- Fresh parsley for garnish
Why we use cream soups: They create the base of our creamy sauce without requiring a separate roux. Best substitute: Make your own by mixing 1 cup milk with 3 tablespoons flour and seasonings.
Why sour cream matters: It adds tanginess that balances the richness. If you don’t have sour cream, Greek yogurt works perfectly.
Cheese choice: Sharp cheddar provides the best flavor, but Monterey Jack or Mexican blend work beautifully for a milder taste.
Step-by-Step Instructions
- Spray your 6-quart crockpot with cooking spray to prevent sticking and make cleanup easier later.
- Add the shredded chicken, diced onion, bell pepper, and minced garlic to the bottom of the crockpot, spreading evenly.
- In a large bowl, whisk together both cream soups, chicken broth, and Italian seasoning until smooth and well combined.
- Pour the soup mixture over the chicken and vegetables, stirring gently to coat everything. This ensures even flavor distribution.
- Cover and cook on LOW for 3-4 hours or HIGH for 1.5-2 hours until the mixture is hot and bubbly.
- About 30 minutes before serving, break the spaghetti in half and stir it into the crockpot, ensuring pasta is submerged.
- Cover and continue cooking until spaghetti is tender, stirring once halfway through. If it looks dry, add a splash of broth.
- Stir in sour cream and 1.5 cups of cheese until melted and creamy. Season with salt and pepper to taste.
- Sprinkle remaining cheese on top, cover for 5 minutes to melt, then garnish with fresh parsley before serving.
Serving Suggestions
This crockpot chicken spaghetti is perfect for Sunday family dinners when everyone gathers around the table. Serve it straight from the crockpot with a simple green salad and garlic bread for a complete meal. For game day parties or potlucks, this dish travels well and stays warm in the crockpot for hours.
I love serving this with roasted vegetables or steamed broccoli on the side to add some color and nutrition. During cooler months, pair it with a bowl of tomato soup for the ultimate comfort food combination.
Variations and Suggestions (Make it Yours)
- Add 1 cup of frozen peas or corn during the last 15 minutes for extra vegetables and color
- Make it spicy by stirring in diced jalapeños or a can of Rotel tomatoes with the soup mixture
- Use whole wheat or gluten-free pasta to accommodate dietary preferences without changing the cooking method
- Replace chicken with turkey for a Thanksgiving leftover transformation
- Create a lighter version by using Greek yogurt instead of sour cream and reducing the cheese to 1 cup
- Add mushrooms, spinach, or sun-dried tomatoes for more depth of flavor
Emily Dawson Tips for Recipe Success
Don’t add the pasta at the beginning. This is the most common mistake I see. Pasta needs only 30-40 minutes in the crockpot, or it becomes mushy and absorbs too much liquid.
Stir the pasta after adding it to ensure every strand gets coated with liquid. I learned this the hard way when half my noodles stuck together in a clump.
Use rotisserie chicken from the store to save time. I remove the skin and pull the meat while watching TV the night before, storing it in the fridge.
If your sauce looks too thick after cooking, thin it with chicken broth or milk one tablespoon at a time until you reach your desired consistency.
Reserve some pasta water when draining if you cook the spaghetti separately. This starchy water helps the sauce cling to the noodles better.
Storage and Make-Ahead
Store leftovers in an airtight container in the refrigerator for up to 4 days. The pasta will absorb more sauce as it sits, so I always add a splash of milk or broth when reheating to restore the creamy texture.
For freezing, portion the cooled spaghetti into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating. I don’t recommend freezing dishes with sour cream if you want the best texture, but it’s still perfectly edible.
Reheat individual portions in the microwave with a damp paper towel on top to prevent drying. For larger amounts, warm gently on the stovetop over medium-low heat, stirring frequently and adding liquid as needed.
Frequently Asked Questions
Can I use uncooked chicken in this recipe?
Yes, but add it at the beginning and cook on LOW for 4-5 hours or HIGH for 2-3 hours before adding the pasta. Make sure the internal temperature reaches 165°F for food safety. I prefer starting with cooked chicken for better texture and time savings.
Why is my pasta mushy?
You likely added it too early or cooked it too long. Pasta should only be in the crockpot for the final 30-40 minutes. If you’re worried about timing, cook the pasta separately and stir it in just before serving.
Can I make this without cream soups?
Absolutely. Make a roux by melting 4 tablespoons butter, whisking in 4 tablespoons flour, then slowly adding 2 cups of milk while stirring. Season with garlic powder, onion powder, salt, and pepper for a homemade cream sauce.
What if I don’t have a crockpot?
You can make this on the stovetop in a large pot or Dutch oven. Simmer the chicken mixture for 15-20 minutes, add the cooked pasta, then stir in the sour cream and cheese. It takes about 30 minutes total.
How do I prevent the cheese from becoming grainy?
Add the cheese at the very end when the crockpot is turned off or on warm setting. Stir gently until melted. High heat causes cheese proteins to separate, creating that grainy texture nobody wants.
Can I double this recipe?
Yes, but use a 7-quart or larger crockpot to ensure everything cooks evenly. You may need to add 15-20 minutes to the pasta cooking time since there’s more volume to heat through.
Final Thoughts
This creamy crockpot chicken spaghetti has become one of my most-requested recipes, and I completely understand why. It’s that rare combination of effortless and impressive, feeding a crowd without keeping you tied to the kitchen. I hope it becomes a staple in your home too.
