Ingredients You’ll Need

Chicken and Pasta

2 pounds boneless skinless chicken breasts
- You can use chicken thighs if you prefer richer flavor and extra tenderness.
12 ounces penne pasta or rotini
- Use any short pasta that holds sauce well; whole wheat or gluten free pasta also works with a slightly firmer texture.

Creamy Cajun Sauce

2 cups low sodium chicken broth
- I like Better Than Bouillon mixed with water for strong flavor.
1 cup heavy cream
- Half and half works if you want it a bit lighter, though the sauce turns slightly thinner.
8 ounces cream cheese, softened and cubed
- Use full fat for the creamiest texture; store brand works just fine.
1 can (10.5 ounces) condensed cream of chicken soup
- This shortcut adds body and flavor with almost no effort.
1 can (14.5 ounces) diced tomatoes with green chiles, undrained
- Rotel style tomatoes add a nice kick; use mild if cooking for kids.
3 tablespoons Cajun seasoning
- Use a low sodium blend if possible; brands like Tony Chachere’s or Slap Ya Mama taste great, just watch the salt.
1 teaspoon smoked paprika
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon dried thyme
1 teaspoon dried oregano
1 teaspoon sugar
- This tiny bit balances the acidity from tomatoes.
½ teaspoon black pepper
¼ to ½ teaspoon cayenne pepper, optional
- Add more if you love heat, skip it for a milder pasta.

Veggies & Mix-ins

1 red bell pepper, sliced
1 green bell pepper, sliced
1 small yellow onion, thinly sliced
3 cloves garlic, minced
½ cup grated Parmesan cheese
2 tablespoons butter
2 tablespoons chopped fresh parsley or green onions for garnish

Pantry Shortcuts & Substitutions

Use pre-sliced frozen bell pepper and onion mix to save chopping time.
Use jarred minced garlic if you do not feel like peeling cloves.
Swap cream cheese with Neufchâtel if you want a slightly lighter sauce.
Use cooked shredded rotisserie chicken and cut the slow cooker time in half.

Equipment List

6 quart or larger Crock Pot or slow cooker
Cutting board and sharp knife
Measuring cups and spoons
Wooden spoon or silicone spatula
Small whisk
Large pot for boiling pasta
Colander for draining pasta

Tips & Tricks

Pat the chicken dry and coat it lightly with Cajun seasoning so the flavor sticks and browns better in the slow cooker.
Use a slow cooker liner or spray the insert with cooking spray to make cleanup easier.
Keep the cream cheese at room temperature so it melts into the sauce smoothly and does not clump.
Add the pasta near the end and cook it separately so it stays al dente and does not turn mushy.
Taste the sauce before adding extra salt because many Cajun blends already contain a lot of sodium.
Stir the slow cooker contents gently after adding dairy to keep the sauce silky and prevent curdling.
Cut the chicken into large chunks if you want pieces, or leave breasts whole and shred them at the end.
Use mild diced tomatoes with green chiles for kids or spice-sensitive eaters and pass extra Cajun seasoning at the table.

How to Make Crock Pot Creamy Cajun Chicken Pasta Recipe

Step 1: Season the Chicken

Place the chicken breasts on a cutting board and pat them dry with paper towels. Sprinkle 1 to 2 tablespoons of Cajun seasoning, smoked paprika, garlic powder, onion powder, thyme, oregano, black pepper, and sugar over both sides. Rub the spices into the chicken so every surface gets coated.

Step 2: Load the Crock Pot

Add sliced bell peppers and onions to the bottom of the slow cooker. Place the seasoned chicken on top of the veggies. Sprinkle minced garlic over the chicken.

Step 3: Mix the Sauce Base

In a medium bowl, whisk together chicken broth, cream of chicken soup, diced tomatoes with green chiles, and the remaining Cajun seasoning. Pour this mixture evenly over the chicken and vegetables. Dot the top with the cubed cream cheese.

Step 4: Cook the Chicken

Cover the Crock Pot with the lid. Cook on low for 4 to 5 hours or on high for about 2½ to 3 hours, until the chicken feels very tender and reaches 165°F internally. Stir once halfway through if you can, so the cream cheese blends into the sauce.

Step 5: Shred or Slice the Chicken

When the chicken finishes cooking, transfer it to a cutting board. Shred it with two forks or slice it into bite-size pieces. Return the chicken to the Crock Pot and stir it into the creamy Cajun sauce.

Step 6: Cook the Pasta

About 20 minutes before serving, bring a large pot of salted water to a boil. Add the pasta and cook it to al dente according to package directions. Drain the pasta well and drizzle with a little butter so it does not stick.

Step 7: Combine Pasta and Sauce

Add the hot cooked pasta to the Crock Pot. Sprinkle in the Parmesan cheese and butter. Stir gently until the pasta gets coated in the creamy Cajun sauce and everything looks well combined.

Step 8: Adjust and Garnish

Taste the pasta and add extra Cajun seasoning, black pepper, or a splash of cream if you want a richer sauce. Let the pasta sit on warm for 5 to 10 minutes so it thickens slightly. Top with chopped parsley or green onions right before serving.

What to Serve with Crock Pot Creamy Cajun Chicken Pasta Recipe

Serve this Crock Pot Creamy Cajun Chicken Pasta Recipe with a crisp green salad tossed in a light vinaigrette to balance the richness. Garlic bread or warm French bread works perfectly to soak up every last bit of sauce. Steamed broccoli, green beans, or roasted asparagus add color and crunch on the side. Pair it with iced tea, lemonade, or sparkling water with citrus slices for a refreshing drink.

Storage Options

Store leftovers in an airtight container in the fridge for up to 3 to 4 days.
Add a splash of milk or cream before reheating to loosen the sauce.
Reheat gently on the stove over low heat, stirring often, or in the microwave in short bursts, stirring between each.
Freeze portions in freezer safe containers for up to 2 months, then thaw overnight in the fridge before reheating.
Avoid repeated reheating cycles so the pasta does not turn too soft.
