Creamy Crockpot Chicken Spaghetti | Easy Weeknight Dinner
Crockpot Chicken Spaghetti is a slow cooker dinner that turns chicken breasts, diced tomatoes with green chilies, and melted cheese into a creamy sauce for pasta. It needs almost no hands-on work, and the chicken shreds right in the pot once it's done.
The short ingredient list leans on cream cheese, Rotel-style tomatoes, and sharp cheddar for flavor. Make a batch tonight and you'll have dinner on the table with barely any cleanup.

Getting the Texture Right
The chicken breasts go in whole and cook low and slow until they shred with almost no resistance from two forks. You'll know they're ready when the meat falls apart at the edges and the juices run clear, not pink. Don't rush this part by cooking on high the whole time; low heat keeps the chicken moist instead of stringy and dry.
Once shredded, stir the chicken back into the sauce so every strand picks up the tomato and cheese flavor. The cream cheese should melt into small, glossy streaks, not clumps. If it looks grainy, a quick whisk right in the crockpot smooths it out before the pasta goes in.
Why This Recipe Works
- One pot, little cleanup. Everything cooks in the crockpot except the spaghetti itself, so you're only washing one big dish.
- Hands-off cooking. You load the slow cooker in the morning and come back to shredded chicken in a ready sauce.
- Kid-friendly flavor. The creamy, cheesy sauce is mild enough for picky eaters, with the option to add heat for the adults.
Ingredients for Chicken Spaghetti
-
Chicken breasts – the protein base; boneless thighs work too and stay even juicier after the long cook.
-
Rotel-style diced tomatoes with green chilies – brings tang and a little kick; swap in plain diced tomatoes plus a pinch of chili powder if you want it milder.
-
Cream of chicken soup – thickens the sauce and adds savory depth; cream of mushroom soup is a solid stand-in.
-
Cream cheese – makes the sauce rich and smooth; reduced-fat cream cheese works fine if you want to lighten it up.
-
Chicken broth – thins the sauce to coat the pasta without drying it out.
-
Sharp cheddar cheese – melts into the sauce and tops the dish; Monterey Jack is a gentler alternative.
-
Spaghetti – cooked separately and stirred in at the end; thin spaghetti or linguine both hold the sauce well.
-
Garlic powder and onion powder – season the sauce without extra chopping; fresh minced garlic and onion can replace them if you have time to sauté first.

How We Make Chicken Spaghetti
- Load the crockpot. Place the chicken breasts in the bottom, then pour the Rotel, cream of chicken soup, broth, and seasonings over the top.
- Cook low and slow. Cover and cook on low for 6 hours, or until the chicken shreds easily with two forks.
- Shred the chicken. Remove the chicken, shred it on a cutting board, then return it to the crockpot.
- Melt in the cream cheese. Cut the cream cheese into cubes, stir them into the hot sauce, and whisk until smooth, about 5 minutes.
- Boil the spaghetti. While the sauce finishes, cook the spaghetti separately until just al dente, then drain.
- Combine and serve. Stir the drained spaghetti into the crockpot along with half the cheddar, then sprinkle the rest on top and let it melt for a few minutes before serving.
Keeping and Reheating
Leftover Crockpot Chicken Spaghetti keeps in the fridge for up to 4 days in a sealed container; the sauce thickens as it cools, which is normal. Freeze portions for up to 2 months and thaw overnight in the fridge before reheating. Warm it on the stovetop over medium-low heat with a splash of chicken broth or milk, stirring until the sauce loosens back up, about 5-7 minutes.
Before You Make Chicken Spaghetti
Is Rotel the same as regular diced tomatoes?
Rotel is diced tomatoes mixed with green chilies, so it adds heat that plain tomatoes don't have. Use regular diced tomatoes with a pinch of chili powder if you prefer a milder sauce.
Can I cook the spaghetti in the crockpot too?
We don't recommend it here, since pasta cooked directly in the slow cooker with this much sauce tends to turn mushy. Boiling it separately keeps the noodles firm.
What if my sauce looks too thin?
Let it sit uncovered on warm for 10-15 minutes before adding the pasta, which lets some liquid evaporate. The sauce also thickens more once the spaghetti absorbs some of it.
Can I make this ahead for a busy week?
Shred and sauce the chicken a day ahead, then reheat it and add freshly cooked pasta right before serving. This keeps the noodles from soaking up too much liquid in storage.

Ingredients
Method
- Load the slow cooker: Place the chicken breasts in the bottom of the crockpot. Pour the diced tomatoes with green chilies, cream of chicken soup, and chicken broth over the top.
- Add seasoning: Sprinkle garlic powder, onion powder, and black pepper over the mixture. Stir gently around the chicken to combine the liquids without lifting the breasts out.
- Cook on low: Cover and cook on low for 6 hours, until the chicken shreds easily with two forks and the juices run clear.
- Shred the chicken: Remove the chicken breasts to a cutting board and shred them into bite-sized pieces using two forks.
- Return chicken to sauce: Add the shredded chicken back into the crockpot and stir it into the warm sauce so every piece gets coated.
- Melt in cream cheese: Add the cubed cream cheese to the hot sauce and whisk until fully melted and smooth, about 5 minutes.
- Boil the spaghetti: While the sauce finishes, cook the spaghetti in a pot of salted boiling water until just al dente, about 8-9 minutes, then drain.
- Combine pasta and sauce: Add the drained spaghetti to the crockpot along with 1 cup of the shredded cheddar. Stir until the pasta is evenly coated in the creamy sauce.
- Melt the topping: Sprinkle the remaining cheddar cheese over the top, cover, and let it sit on warm for 5-10 minutes until melted.
- Serve: Taste and adjust salt if needed, then garnish with chopped parsley before spooning into bowls.
