Ingredients for the Best Crockpot Chicken Spaghetti
- Boneless skinless chicken breasts: Boneless skinless chicken thighs are a great substitute for chicken breasts.
- Minced garlic
- Kosher salt
- Fresh cracked black pepper
- Onion powder
- Italian seasoning
- Cream of chicken soup: Feel free to use another kind of condensed cream soup that you prefer. I made my meal with the classic cream of chicken, but you can try other flavors like cream of celery, cream of onion, or cream of mushroom soup.
- Diced tomatoes and green chiles (We used Rotel tomatoes): If you prefer a little less heat in this crockpot spaghetti recipe, you can use a can of petite diced tomatoes instead of the can of Rotel.
- Colby jack cheese: I always prefer using freshly shredded cheese because it melts smoother and tastes so much better. Feel free to ty other cheeses, like cheddar cheese, mozzarella cheese, Monterey or Pepper Jack cheese, or parmesan cheese.
- Cream cheese
- Spaghetti: Angel hair pasta and thin spaghetti are good substitutes for regular spaghetti noodles, although linguine and fettuccine will work well too.

Serving Suggestions for Cheesy Chicken Spaghetti
This pasta dish lacks greens, so I love serving it with a side salad or vegetable to accompany it. My go-to is sautéed green beans, brussels sprouts or asparagus.
You can’t go wrong serving a spaghetti dish like this with a side of bread. Our Cauliflower Breadsticks are perfect if you are looking for a low-carb option or to sneak in some veggies. We also love our Cheesy Pull-Apart Garlic Bread or our Caprese Garlic Bread. They are especially great for sopping up any leftover sauce from your plate!
Tips for Perfect Slow Cooker Chicken Spaghetti
- Prepare The Pasta: It is very important to cook the spaghetti as directed on the package instructions and not to over cook the noodles. Draining the noodles will also stop the cooking process and prevent them from becoming mushy.
- Serve It Spicier: f you want a spicier version of this crock pot chicken spaghetti, you can use hot diced tomatoes and green chilies or add ¼ to ½ teaspoon of chili powder or red pepper flakes to the sauce.
- Grab A Garnish: Sprinkle some fresh chopped parsley or chopped cilantro over your crockpot chicken spaghetti for additional flavor.
- Round Out The Recipe: Feel free to add extra veggies to your crockpot. Corn, peas, broccoli, and carrots, and bell pepper would all be delicious in this dish. It’s a great way to boost the nutrients and make this a complete slow cooker dinner.
Variations To Try
- Make it Creamier: If you want to make this recipe even creamier, Velveeta cheese is a great option instead of shredded cheese. Its smooth, meltable texture blends perfectly into the sauce, giving the chicken spaghetti an ultra-rich and velvety finish. Simply cube the Velveeta and stir it into the mixture during the last 20-30 minutes of cooking for a fuss-free way to switch things up!
- Revise The Recipe: Give it a taco twist like my Crockpot Taco Spaghetti or make it meaty like my Crockpot Spaghetti. You can even prepare your pasta casserole-style and make an oven-baked Rotel Chicken Spaghetti.
- Skip The Spaghetti: For a lower carb count, consider skipping the pasta and serving the chicken over zucchini noodles or broccoli slaw.
