Ingredients You’ll Need

Here’s everything you’ll need to make this slow-cooker chicken spaghetti:

For the Chicken and Sauce:

• 2 boneless, skinless chicken breasts

• 1 can cream of chicken soup

• 1 can cream of mushroom soup

• 1 can diced tomatoes with green chilies (like Rotel), undrained

• 1 block (8 oz) cream cheese, softened

• 1 cup shredded cheddar cheese

• 1 cup chicken broth

• 1 teaspoon garlic powder

• 1 teaspoon onion powder

• Salt and pepper to taste

For the Pasta:

• 12 oz spaghetti

• Water for boiling

• Salt for pasta water

STEP 1: Prep Your Crockpot Ingredients

Start by placing the two boneless chicken breasts into your crockpot. Then add in the rest of your sauce ingredients: both cans of soup (cream of chicken and cream of mushroom), the entire can of undrained diced tomatoes with green chilies, softened cream cheese, shredded cheddar cheese, and chicken broth.

Sprinkle in the garlic powder, onion powder, and a good pinch of salt and pepper. Don’t worry too much about stirring everything perfectly right now—just give it a light mix so the chicken is nicely coated in the cheesy, creamy goodness.

Tip: If your cream cheese isn’t quite softened, you can cube it before adding. It’ll melt beautifully as it cooks.

STEP 2: Slow Cook to Perfection

Cover your slow cooker and set it on low for 6 hours or high for 3 to 4 hours, depending on your schedule. Either way, you’re looking for the chicken to become super tender and easy to shred with a fork.

This is when your kitchen starts to smell amazing—and you’ll start getting those “what are you making?” questions from everyone who walks by.

STEP 3: Shred the Chicken and Get Saucy

Once your chicken is fully cooked and practically falling apart, remove it from the crockpot and place it on a cutting board. Use two forks to shred it into bite-sized pieces.

Then, return the shredded chicken back into the slow cooker. Give it all a good stir so the meat gets coated in that creamy, cheesy sauce that’s been slowly building flavor all day.

Now that your chicken is tender and perfectly shredded, and your sauce is creamy and full of flavor, we’re in the home stretch. This next part is all about bringing it all together into one ridiculously comforting, can’t-stop-eating-it kind of dish.

If you’ve never tried spaghetti made in the crockpot before, this is where the magic really happens. When the pasta mixes into that rich, cheesy sauce and soaks up all the flavor—that’s when you know this recipe’s a keeper.

STEP 4: Boil Your Spaghetti

While your shredded chicken is soaking up all that delicious sauce in the slow cooker, go ahead and get a large pot of salted water boiling on the stove. You’ll want to use about 1–2 teaspoons of salt in the water (don’t skip this—it helps flavor the pasta itself).

Once the water is boiling, add your 12 ounces of spaghetti and cook according to the package instructions until al dente. This usually takes around 8–10 minutes.

Pro tip: Don’t overcook the pasta—it’ll finish softening once it’s stirred into the hot crockpot mixture.

Once it’s done, drain it well and set it aside for a moment.

STEP 5: Combine Pasta with Chicken and Sauce

Now it’s time to bring everything together. Add the cooked spaghetti directly into the crockpot with your shredded chicken and sauce.

Stir it all together gently but thoroughly, making sure every strand of pasta is coated with that rich, cheesy sauce. This part smells so good—and if your family is anything like mine, they’ll be hovering nearby with plates already in hand.

The consistency should be creamy but not runny. If it seems a little too thick, you can add a splash of chicken broth or even a little milk to loosen it up. If it feels too thin, don’t worry—the next step fixes that.

STEP 6: Let It Sit and Soak Up the Flavor

Once everything is mixed together, set your crockpot to “warm” and let the spaghetti sit for about 10 minutes before serving.

This gives the pasta a chance to soak in all that flavor and allows the sauce to thicken slightly for that ultra-cozy, creamy texture we all love in comfort food.

Make It Your Own: Easy Add-Ins and Variations

One of my favorite things about this recipe is how easy it is to tweak based on what you have in your kitchen. Here are a few simple ideas to customize your Crockpot Chicken Spaghetti:

• Add Veggies: Stir in some sautéed bell peppers, mushrooms, or spinach right before serving for added nutrition and color.

• Make It Spicy: Use a can of hot Rotel or add a pinch of cayenne pepper or red pepper flakes for a kick.

• Swap the Protein: If you’re in a pinch for time, use shredded rotisserie chicken instead of raw chicken breasts. Just stir it in during the last hour of cooking.

• Try a Different Cheese: Want extra cheesiness? Mix in some mozzarella or pepper jack with the cheddar for even more melty goodness.

• Gluten-Free Version: Use gluten-free spaghetti and make sure your canned soups are certified gluten-free.

Serving Suggestions

While this dish can totally stand on its own, here are a few easy pairings to round out the meal:

• Garlic Bread – Because carbs on carbs is always a good idea when comfort food is involved.

• Simple Green Salad – A little freshness to balance the richness of the pasta.

• Steamed Broccoli or Roasted Veggies – Adds color, crunch, and nutrients to your plate.

And honestly, it’s so hearty that even a big scoop in a bowl with a sprinkle of extra cheese on top is all you really need. Leftovers? Even better the next day.
