CREAMY CROCKPOT CHICKEN SPAGHETTI INGREDIENTS

You’ll need:

• 2 pounds of boneless, skinless chicken breasts

• 2 (10.5-ounce) cans of condensed cream of chicken soup

• 1 (10-ounce) can of diced tomatoes with green chiles, undrained

• ½ cup of low-sodium chicken broth

• 1 small yellow onion, finely diced (about ¾ cup)

• 3 cloves of garlic, minced

• 1 teaspoon of Italian seasoning

• ½ teaspoon of smoked paprika

• ¼ teaspoon of ground black pepper

• 8 ounces of cream cheese, softened and cut into cubes

• 2 cups of freshly shredded sharp cheddar cheese, divided

• 12 ounces of dry spaghetti noodles

• 2 tablespoons of freshly chopped parsley, optional garnish

INGREDIENT NOTES

CHICKEN: Boneless, skinless chicken breasts work especially well because they become tender enough to shred after slow cooking. Choose chicken breasts that are similar in thickness so they cook evenly.

CREAM OF CHICKEN SOUP: The condensed soup gives the sauce its creamy consistency and adds savory chicken flavor. Use the soup straight from the can without adding the water suggested on the label.

TOMATOES WITH GREEN CHILES: These add a little tanginess and mild heat that balances the rich cheese sauce. The liquid from the can also helps create the right consistency.

CREAM CHEESE: Full-fat cream cheese produces a richer sauce. Allow it to soften before adding it to the crockpot so it melts more easily.

CHEDDAR CHEESE: Sharp cheddar provides plenty of cheesy flavor. Freshly shredded cheese generally melts more smoothly than packaged shredded cheese.

SPAGHETTI: Regular spaghetti noodles are the best choice for this recipe. Cook them separately before stirring them into the creamy chicken mixture.

HOW TO MAKE CROCKPOT CHICKEN SPAGHETTI

This easy dinner comes together in a few simple steps. The most important part is allowing the chicken to cook until tender before adding the cream cheese, shredded cheddar, and spaghetti.

For this recipe, a six-quart slow cooker provides enough room to mix everything together comfortably.

STEP ONE: PREPARE THE SLOW COOKER

Lightly coat the inside of a six-quart crockpot with nonstick cooking spray.

Place the boneless, skinless chicken breasts in a single layer along the bottom of the slow cooker.

Sprinkle the Italian seasoning, smoked paprika, and black pepper evenly over the chicken.

PRO TIP:

If your chicken breasts are especially thick, you can slice them horizontally into thinner pieces. This helps them cook more evenly, although you should still check the internal temperature before shredding.

STEP TWO: ADD THE CREAMY SAUCE INGREDIENTS

In a medium mixing bowl, combine the condensed cream of chicken soup, chicken broth, diced tomatoes with green chiles, diced onion, and minced garlic.

Stir until everything is well mixed.

Pour the mixture over the seasoned chicken breasts, spreading it evenly to cover the meat.

There’s no need to add extra water. The broth and juices released from the chicken will provide additional moisture as everything cooks.

STEP THREE: SLOW COOK THE CHICKEN

Cover the crockpot with the lid and cook on LOW for four to five hours or HIGH for two to three hours.

The cooking time will depend on the size of the chicken breasts and your slow cooker.

The chicken is ready when its thickest part reaches an internal temperature of 165°F and it shreds easily with two forks.

PRO TIP:

Avoid lifting the lid repeatedly while the chicken cooks. Each time you remove the lid, heat escapes and can extend the cooking time.

STEP FOUR: SHRED THE CHICKEN

Carefully remove the cooked chicken breasts from the slow cooker and transfer them to a large plate or cutting board.

Using two forks, shred the chicken into bite-sized pieces.

You can leave a few slightly larger pieces if you prefer more texture in your finished dish.

Keep the creamy cooking liquid in the crockpot. This will become the base of your cheese sauce.

STEP FIVE: ADD THE CREAM CHEESE

Add the softened cream cheese cubes to the hot sauce in the slow cooker.

Replace the lid and allow the cream cheese to soften for about 10 to 15 minutes on LOW.

Stir thoroughly until the cream cheese melts and the sauce becomes smooth.

Add 1½ cups of shredded cheddar cheese, stirring until melted and combined.

PRO TIP:

If the cream cheese doesn’t blend immediately, use a whisk to gently work it into the warm sauce before returning the shredded chicken.

STEP SIX: COOK THE SPAGHETTI

While the cream cheese softens, bring a large pot of salted water to a boil.

Add the spaghetti and cook according to the package directions until al dente.

Drain the pasta, reserving about one cup of pasta water in case you need to thin the sauce.

Avoid overcooking the noodles. They will soften slightly more once mixed with the hot chicken and cheese sauce.

STEP SEVEN: COMBINE EVERYTHING

Return the shredded chicken to the crockpot and stir until coated with the cheese sauce.

Add the drained spaghetti a little at a time, using tongs to gently toss everything together.

Continue mixing until the noodles are evenly coated and the chicken is distributed throughout.

If the sauce seems too thick, add a few tablespoons of reserved pasta water until you reach your preferred consistency.

STEP EIGHT: ADD THE REMAINING CHEESE

Sprinkle the remaining ½ cup of shredded cheddar cheese evenly over the top.

Cover the slow cooker for another five minutes, just until the cheese melts.

Garnish with freshly chopped parsley, if desired, and serve immediately while the spaghetti is hot and creamy.

TIPS FOR THE BEST SLOW COOKER CHICKEN SPAGHETTI

A few simple tips will help you get tender chicken, perfectly cooked noodles, and a creamy sauce.

DON’T OVERCOOK THE CHICKEN: Chicken breasts can become dry when left cooking too long. Check for doneness toward the beginning of the recommended cooking window.

COOK THE SPAGHETTI SEPARATELY: Adding uncooked spaghetti directly to the crockpot can result in unevenly cooked noodles. Boiling the pasta separately gives you better control over its texture.

ADD CHEESE NEAR THE END: Cream cheese and cheddar don’t need several hours of cooking. Adding them after the chicken is done helps prevent the sauce from becoming grainy or separating.

SHRED YOUR OWN CHEESE: Block cheddar melts easily and makes the sauce especially smooth.

WATCH THE SALT: Condensed soup and cheddar already contain salt. Taste the finished sauce before deciding whether to add any extra.

SERVE WHILE HOT: The spaghetti will continue absorbing the creamy sauce as it sits. For the best texture, serve soon after combining everything.

CROCKPOT CHICKEN SPAGHETTI SUBSTITUTIONS AND ADDITIONS

This creamy chicken spaghetti recipe is easy to customize with different cheeses, vegetables, and seasonings.

CHICKEN THIGHS: Replace the chicken breasts with two pounds of boneless, skinless chicken thighs. They have a slightly richer flavor and stay tender during slow cooking.

CREAM OF MUSHROOM SOUP: Substitute one can of cream of chicken soup with a can of condensed cream of mushroom soup for a more savory, earthy flavor.

CHEESE: Monterey Jack, Colby Jack, or a Mexican cheese blend can replace some or all of the cheddar. Pepper Jack is another delicious option if you enjoy a little extra heat.

VEGETABLES: Add one cup of diced bell peppers with the onions for more color and flavor. You could also stir in a cup of thawed frozen peas during the final 10 minutes.

PASTA: Thin spaghetti, linguine, or fettuccine would work well. Penne and rotini are also good choices because their shapes hold the thick sauce nicely.

SPICE: For a spicier version, add ¼ teaspoon of cayenne pepper or ½ teaspoon of crushed red pepper flakes. You can also choose hot diced tomatoes with green chiles.

LIGHTER OPTIONS: Reduced-fat cream cheese can be substituted, although the sauce may be slightly less rich. Low-sodium condensed soup is another good option when available.

HOW TO KEEP CHICKEN SPAGHETTI CREAMY

The sauce should be thick enough to coat the spaghetti without becoming dry or sticky.

One common issue with creamy pasta recipes is that the noodles continue absorbing liquid after they’re cooked. This is especially noticeable when pasta sits in a warm slow cooker.

If the chicken spaghetti becomes too thick, stir in a small amount of warm chicken broth, milk, or reserved pasta water. Start with two tablespoons and add more only as needed.

If the sauce looks too thin before adding the spaghetti, leave the lid off for a few minutes while stirring gently. The noodles will absorb some of the excess liquid once combined.

Avoid adding extra cheese to thicken a watery sauce right away. Too much cheese can create a heavy, sticky texture instead of the smooth consistency you’re looking for.

And don’t leave the finished spaghetti on the WARM setting for several hours. The noodles can become overly soft, even when the sauce initially looks perfect.

WHAT TO SERVE WITH CREAMY CROCKPOT CHICKEN SPAGHETTI

This creamy chicken spaghetti is a filling meal on its own, but a few simple side dishes make it even better.

Garlic Bread: Warm, buttery garlic bread is perfect for soaking up any extra cheese sauce left on your plate.

Green Salad: A crisp garden salad with tomatoes, cucumbers, and a light dressing provides a fresh contrast to the rich pasta.

Roasted Vegetables: Broccoli, asparagus, or roasted carrots add color and make the meal feel more complete.

Dinner Rolls: Soft homemade rolls or warm crusty bread are delicious alongside this hearty chicken dinner.

Steamed Green Beans: Lightly seasoned green beans are a simple choice that doesn’t compete with the creamy sauce.

For family dinners, I especially like pairing this pasta with a fresh salad and garlic bread. The combination is easy to prepare and gives everyone a little variety on their plate.

HOW TO STORE CROCKPOT CHICKEN SPAGHETTI

This recipe makes generous portions, and leftovers are convenient for lunch or another easy dinner.

MAKE AHEAD

You can prepare the chicken and sauce ingredients the night before.

Store the raw chicken separately from the mixed sauce ingredients in covered containers in the refrigerator.

When you’re ready to cook, assemble everything in the crockpot and follow the recipe instructions.

For the best results, wait until shortly before serving to cook the spaghetti and add the cheeses.

IN THE FRIDGE

Store leftover chicken spaghetti in an airtight container in the refrigerator for up to three to four days.

Refrigerate leftovers within two hours of cooking, using shallow containers to help the food cool quickly.

Keep in mind that the spaghetti may absorb more sauce during storage, making it thicker the following day.

IN THE FREEZER

For the best texture, freeze the cooked chicken and sauce before combining them with the spaghetti.

Allow the mixture to cool, then transfer it into freezer-safe containers. Freeze for up to two months for the best quality.

Cream-based sauces may separate slightly after freezing. Gentle reheating and stirring can help bring the sauce back together.

Cook fresh spaghetti when you’re ready to serve.

REHEATING

Reheat individual servings in the microwave in short intervals, stirring between each one.

Add a splash of milk or chicken broth to loosen the sauce.

For larger portions, warm the spaghetti in a covered skillet over low heat, stirring occasionally.

Heat leftovers thoroughly to 165°F before serving.

FREQUENTLY ASKED QUESTIONS

Can I put raw chicken in the crockpot for chicken spaghetti?

Yes. Raw, fully thawed chicken breasts can go directly into the slow cooker with the sauce ingredients. There’s no need to cook or brown them beforehand. Make sure the chicken reaches an internal temperature of 165°F before shredding.

Can I add uncooked spaghetti directly to the slow cooker?

It’s best to cook the spaghetti separately. Dry noodles need enough liquid and controlled cooking time to soften evenly. Adding them directly to this thick sauce may result in noodles that are sticky, mushy, or unevenly cooked.

Can I make this recipe without cream cheese?

You can leave out the cream cheese, although the finished sauce will be less thick and creamy. The condensed soup and cheddar still provide plenty of flavor. Start with less chicken broth if you want a thicker consistency.

Why is my crockpot chicken spaghetti watery?

Chicken releases liquid as it cooks, and some slow cookers retain more moisture than others. If the sauce looks thin, stir it well after adding the cream cheese and cheddar. The cooked pasta will absorb some liquid, too. You can also leave the lid off briefly to allow a little moisture to evaporate.

Can I use frozen chicken breasts?

Thaw frozen chicken completely in the refrigerator before placing it in the slow cooker. Frozen chicken can take too long to heat safely in a crockpot. Once thawed, follow the recipe instructions and check the internal temperature before serving.

Can I keep chicken spaghetti warm in the crockpot?

You can use the WARM setting briefly after the dish is finished, provided the food stays at 140°F or above. However, the spaghetti will continue absorbing the sauce and become softer over time. It’s better to serve the pasta shortly after mixing everything together.
