Ingredients You’ll Need
One of my favorite things about this Crockpot Chicken Spaghetti Recipe is how it weaves simple, everyday staples into something absolutely crave-worthy. Each ingredient adds its own magic, whether it’s a pop of freshness, silky texture, a creamy base, or that irresistible cheesy finish.
- Yellow onion: Diced finely, it melts into the sauce, bringing a sweet, savory depth to every bite.
- Red bell pepper: These add a gentle sweetness and a bold pop of color that makes the dish gorgeous.
- Green bell pepper: Adds fresh, slightly peppery flavors that perfectly balance the creaminess.
- Mild diced green chiles (4 oz can): Don’t worry, these offer flavor more than heat, giving the casserole subtle Southwest flair.
- Cumin: Just a half teaspoon gives warmth and a hint of earthiness without overpowering the sauce.
- Garlic powder: Infuses savory goodness throughout each forkful—don’t skip it!
- Salt & pepper: Essential for seasoning and unlocking all those delicious flavors. Always taste and adjust at the end.
- Chicken breasts (1 lb): Two average-sized chicken breasts are perfect for shredding and keeping the casserole hearty and lean.
- Cream of chicken soup (10.5 oz can): Works great for silky texture, but cream of mushroom is a tasty twist if that’s your preference.
- Spaghetti (3/4–1 lb, cooked): The ultimate comfort food base—go for 3/4 pound if you like it extra saucy.
- Cheddar cheese (3 cups, grated): Make it freshly grated for the meltiest, creamiest result. The sharper the better!
- Chicken stock (a few splashes, optional): Keeps the sauce luscious and saucy, especially if you like it extra creamy.
How to Make Crockpot Chicken Spaghetti Recipe
Step 1: Layer and Mix Your Ingredients
Start by adding the diced onion, both bell peppers, green chiles, cumin, garlic powder, salt, pepper, raw chicken breasts, the condensed soup, and about one cup of the grated cheddar cheese into your crockpot. Give everything a good stir to make sure those flavors start mingling right away. This little step ensures the veggies cook evenly and the chicken gets seasoned from all angles.
Step 2: Slow Cook Until Chicken Is Perfectly Tender
Set your slow cooker to high and let it work its magic for about 3 to 4 hours. That’s just enough time for the chicken to become fork-tender and soak up all those aromatic veggies and spices. Once the chicken is cooked through (check that it’s no longer pink inside), remove the breasts and shred them easily with two forks—a task I always find oddly satisfying! Tumble the shredded chicken back into the crockpot and give it a gentle stir.
Step 3: Add Pasta and Cheese for Creamy, Cheesy Goodness
Now, add in your cooked spaghetti and the rest of your glorious cheddar cheese. Toss everything so the pasta is evenly coated in sauce and the cheese begins to melt into every nook and cranny. If you like your sauce a little looser, a splash or two of chicken stock is your secret weapon. Switch the crockpot to low and let everything get extra cozy together for another 20 to 30 minutes before serving.
How to Serve Crockpot Chicken Spaghetti Recipe

Garnishes
Brighten up your Crockpot Chicken Spaghetti Recipe with a handful of freshly chopped parsley, some sliced green onions, or even a sprinkle of crushed red pepper for heat. A little extra cheddar never hurt, either! This finishing touch adds color and a fresh pop to each plate.
Side Dishes
While this dish is hearty enough on its own, I love serving it alongside a crisp green salad and thick slices of garlic bread, perfect for sopping up all that cheesy sauce. For an easy family dinner, steamed broccoli or simple roasted veggies make it a wholesome, complete meal.
Creative Ways to Present
Why not serve your Crockpot Chicken Spaghetti Recipe in individual ramekins or oven-safe bowls, broiling them for a bubbly, golden finish? Or, scoop it into bell pepper halves and bake for a lighter, colorful spin. Leftovers even make a fantastic sandwich filling—just stuff in a roll and bake with more cheese on top.
Make Ahead and Storage
Storing Leftovers
Let any leftover Crockpot Chicken Spaghetti Recipe cool completely before transferring it into an airtight container. It’ll keep happily in the fridge for up to four days, making for quick, satisfying meals all week. The flavors even deepen a bit, making each reheat somehow extra delicious!
Freezing
For freezer meals, portion individual servings or the whole batch into freezer-safe containers. This Crockpot Chicken Spaghetti Recipe freezes like a dream for up to three months. When you’re ready to enjoy, thaw overnight in the fridge for best results and reheat as needed.
Reheating
Reheating is a breeze: pop single servings in the microwave until piping hot, or warm larger portions in a covered baking dish at 350°F. Add a splash of chicken stock or milk if you want to restore its creamy, saucy consistency and always top with a sprinkle of fresh cheese before serving again.
FAQs
Can I use other types of pasta in this Crockpot Chicken Spaghetti Recipe?
Absolutely! While spaghetti is traditional (and delicious), feel free to swap in fettuccine, rotini, or even penne—whatever you have on hand. Just make sure the pasta is cooked before stirring it in.
Is it possible to make this recipe with rotisserie chicken?
Yes, using rotisserie chicken is a great time-saver! Just skip the slow-cooking step for the chicken. Shred the cooked chicken and stir it in for the final short heating phase with the cheese and cooked pasta.

Definitely—simply use your favorite gluten-free pasta, and double-check that your cream of chicken soup is gluten-free as well. All the other primary ingredients are naturally gluten-free, so it’s an easy switch.

Go for it! Mushrooms, corn, or spinach work wonderfully here—just add them to the crockpot at the start with the peppers and onion. They’ll cook down beautifully and add more color and nutrition.
