Ingredients
Below is a list of the ingredients you’ll need to gather to make this recipe, why you need them, and possible substitutions. Scroll all the way down for the full recipe card with measurements.
Jump- Boneless skinless chicken breasts: Trim the chicken of any excess fat. You’ll cook them whole first, and then shred.
- Yellow onion, garlic, and brown mushrooms: Finely dice the mushrooms, so they deliver more flavor and less texture. If you hate mushrooms, you can skip them.
- Rotel: If you like your crockpot chicken spaghetti a bit spicy, go ahead and use hot Rotel. Otherwise, opt for the Original or Mild versions.
- Chicken broth: The chicken broth provides moisture to the chicken so it cooks without burning. It also gives it flavor and acts as a base to the sauce.
- Spaghetti noodles: Cooked separately to al dente. This is important, as they’ll continue to cook a bit once mixed in with the sauce.
- Cream cheese and sour cream: Add a thick and creamy consistency to the dish.
- Seasoning: Garlic powder, paprika, salt, and black pepper
- Shredded sharp cheddar cheese: If you have a block of sharp cheddar, grate it fresh for best results.
- Chopped parsley: For garnish. I always like to elevate even the most casual dishes with some fresh herbs.

How to make Crockpot Chicken Spaghetti
This section shows you how to make this recipe, with process photos showing the steps to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.
Jump- Step One: Add the chicken breasts, onions, mushrooms, garlic, Rotel, and seasoning to the basin of your crockpot. Pour in the broth and stir everything to combine. Cover and cook on LOW for 6 hours (which I recommend for chicken breast) or HIGH for 4 hours (totally doable, but second choice – you know your crockpot best).

- Step Two: Once the chicken is fully cooked, use a pair of tongs to transfer the chicken to a cutting board. You can shred them with two forks or dice them into cubes. Return the chicken to the pot and stir in the cream cheese. Put the over back on and cook on HIGH for 30 more minutes.

- Step Three: During this time, cook the spaghetti according to package directions until al dente, then drain and add it to the crockpot. Stir in the sour cream and cheddar cheese, cover, and cook for another 15 minutes until the cheese has melted.

- Step Four: Let it sit for 10 minutes, uncovered, and once thickened, garnish with fresh parsley and enjoy!

Every slow cooker runs differently. Times given are a general recommendation and should be tested in your own slow cooker and adjusted as needed.
What to serve it with
All this needs is a basket of fresh bread on the table to mop up the sauce with! We love one-hour dinner rolls, copycat Texas Roadhouse rolls, and Little Caesars breadsticks with our pasta dishes.
If you want a side of vegetables or salad, you could do an easy chopped salad or a classic Caesar salad.
- If mushrooms aren’t your thing, you can omit them. Or you can mince them teeny tiny so you don’t notice them as much.
- Let the chicken spaghetti sit for 10 minutes. Doing this gives the sauce a chance to thicken. Toss before serving.
- Reserve a bit of the pasta water. If needed, add it to the crockpot to thin out the sauce. Start with a few tablespoons and go from there.
- Swap the breasts for boneless skinless chicken thighs.
- Use original, mild, or hot rotel.
- You can also use a can of diced tomatoes if you don’t have Rotel. Then, add diced bell peppers and jalapenos for added flavor and texture.
Storage & Reheating
How to store leftovers
Keep any leftover chicken spaghetti in an airtight container in the fridge for up to 3 days.
Reheating Instructions
Reheat it on the stovetop and add a splash of cream or broth to loosen up the sauce. You can also use the microwave.

Notes
- Finely mincing the mushrooms helps add flavor without a noticeable mushroom texture (look for cremini). If you don’t like mushrooms, they can be skipped.
- When cooking the noodles, stop at al dente (1-3 mins before the package states) & reserve a bit of pasta water. The noodles will continue to soften as they sit in the slow cooker.
- Letting the chicken spaghetti rest uncovered for 10 minutes before serving will help thicken the sauce and improve texture. Give the pasta a good toss before serving.
- When tossing the pasta at the end, pour some reserved starchy pasta water to help bring the sauce together. Start by adding 3 tablespoons of water and add more depending on your preference.
- Boneless skinless chicken thighs can be used instead of breasts.
- Original, mild, or hot Rotel works. If you don’t have Rotel, a can of diced tomatoes will also work.
- Add diced bell peppers or jalapenos for added flavor and texture.
- Store covered in the fridge for up to 3 days.
