Why I Love This Recipe
I started making this kind of pasta on days when I wanted a warm, filling dinner without standing over the stove all afternoon. Cajun pasta normally feels like something you need to watch closely, but the crockpot changes that.
The chicken slowly cooks with Cajun seasoning, peppers, onion, garlic, and broth. By the time the cream and Parmesan go in, there is already a flavorful base waiting for them. Then the pasta cooks right in that creamy sauce.
I especially love this recipe because:
- Most of the cooking happens in one crockpot.
- The chicken comes out tender and juicy.
- You can easily control how spicy it is.
- The sauce is creamy without being complicated.
- Cooking the pasta in the sauce means fewer dishes.
- Leftovers reheat surprisingly well with a splash of milk.
What You’ll Need
- 1½ pounds boneless, skinless chicken breasts
- 2 tablespoons Cajun seasoning, divided
- 1 tablespoon olive oil
- 1 medium onion, diced
- 1 red bell pepper, diced
- 3 cloves garlic, minced
- 2 cups low-sodium chicken broth
- 1 teaspoon smoked paprika
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 8 ounces cream cheese, softened and cubed
- 1 cup heavy cream
- 1 cup freshly grated Parmesan cheese
- 12 ounces dry penne pasta
- 2 tablespoons unsalted butter
- 2 tablespoons chopped fresh parsley
Pro Tips
- Start with less Cajun seasoning if you prefer mild food. Cajun seasoning blends vary a lot in heat and salt.
- Use freshly grated Parmesan. It melts more smoothly than many bags of pre-shredded cheese.
- Don’t add the pasta at the beginning. It will become very soft after several hours in the crockpot.
- Check the pasta early. Slow cookers heat differently, so start checking it around 15 minutes after adding it.
- Don’t overcook the chicken. Once it reaches an internal temperature of 165°F, it is ready.
Tools You’ll Need
- 6-quart slow cooker or crockpot
- Cutting board
- Chef’s knife
- Measuring cups
- Measuring spoons
- Cheese grater
- Wooden spoon or silicone spatula
- Two forks
- Instant-read meat thermometer
- Serving spoon
Substitutions and Variations
Chicken thighs: Use 1½ pounds of boneless, skinless chicken thighs instead of chicken breasts. They stay especially juicy during slow cooking.
Different pasta: Rigatoni, rotini, or ziti work well. Cooking time may change slightly.
Lighter sauce: Replace the heavy cream with half-and-half. The finished sauce will be thinner.
Less heat: Reduce the Cajun seasoning to 1 tablespoon total and use a mild Cajun blend.
More heat: Add ¼ teaspoon cayenne pepper or sliced jalapeño.
More vegetables: Add sliced mushrooms along with the onion and bell pepper.
Make Ahead Tips
Dice the onion and red bell pepper and mince the garlic up to 2 days ahead. Keep them covered in the refrigerator.
You can also grate the Parmesan a day or two ahead and refrigerate it in an airtight container.
For the best pasta texture, wait to cook the pasta until the final part of the recipe. Don’t leave uncooked pasta sitting in the liquid all day.
Crockpot Cajun Chicken Pasta Recipe and Instructions
Step 1: Season the Chicken
Pat 1½ pounds boneless, skinless chicken breasts dry. Rub them with 1 tablespoon Cajun seasoning and 1 tablespoon olive oil, coating both sides.
Place the seasoned chicken breasts in the bottom of a 6-quart slow cooker.
Step 2: Add the Vegetables and Broth
Scatter 1 medium diced onion, 1 diced red bell pepper, and 3 minced garlic cloves over and around the seasoned chicken.
Pour in 2 cups low-sodium chicken broth. Sprinkle in the remaining 1 tablespoon Cajun seasoning, 1 teaspoon smoked paprika, ½ teaspoon salt, and ¼ teaspoon black pepper.
Cover the crockpot.
Step 3: Slow Cook the Chicken
Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours, until the chicken is tender and reaches 165°F in the center.
Remove the cooked chicken to a cutting board. Leave all the vegetables and cooking liquid in the crockpot.
Step 4: Make the Creamy Cajun Sauce
Add 8 ounces softened, cubed cream cheese, 1 cup heavy cream, 1 cup freshly grated Parmesan cheese, and 2 tablespoons unsalted butter to the hot broth and vegetables in the crockpot.
Stir until the cream cheese and butter melt and the sauce becomes creamy. Cover and cook on HIGH for about 10 minutes if needed to help everything melt.
Step 5: Shred or Slice the Chicken
While the sauce becomes creamy, use two forks to shred the cooked 1½ pounds Cajun chicken, or cut it into bite-size slices.
Set the chicken aside for a few minutes.
Step 6: Cook the Pasta in the Sauce
Stir 12 ounces dry penne pasta directly into the creamy Cajun sauce.
Make sure most of the pasta is covered by the sauce. Cover and cook on HIGH for about 15–25 minutes, stirring once or twice, until the penne is just tender.
Begin checking at 15 minutes so it doesn’t overcook.
Step 7: Add the Chicken Back
Return all of the shredded Cajun chicken to the crockpot once the penne is tender.
Gently stir until the chicken is evenly mixed with the 12 ounces cooked penne and creamy Cajun sauce. Let everything warm together for about 5 minutes.
If the sauce becomes too thick, stir in a small splash of chicken broth or heavy cream.
Step 8: Garnish and Serve
Turn off the crockpot. Sprinkle the pasta with 2 tablespoons chopped fresh parsley.
Spoon the finished pasta into a serving bowl. Serve warm while the sauce is creamy.
Why This Recipe Works (Quick Science)
Slow cooking gives the chicken time to become tender while its juices flavor the broth. The onion, bell pepper, garlic, and spices also release flavor as they cook.
Cream cheese contains fat and milk proteins that give the sauce body. Heavy cream adds richness, while Parmesan adds both flavor and natural thickening power.
Adding the pasta near the end is important. Pasta absorbs liquid as its starches hydrate. If it went into the crockpot at the beginning, it would absorb too much liquid and become mushy.
The pasta also releases a little starch into the sauce while it cooks. That starch helps the creamy sauce cling to each piece of penne.
Common Mistakes
Adding pasta too early: Don’t put it in with the raw chicken. Add it only near the end.
Using too much Cajun seasoning: Some Cajun blends contain lots of salt and cayenne. Taste your brand before adding extra salt or heat.
Overcooking the chicken: Check for an internal temperature of 165°F rather than cooking it longer than needed.
Using cold cream cheese: Softened, cubed cream cheese melts into the sauce much more easily.
Walking away after adding pasta: The pasta cooks quickly. Check it at 15 minutes and stir so it cooks evenly.
Expecting every crockpot to cook the same: Slow cookers vary in temperature. Use the times as a guide and check the food itself.
What to Serve With Crockpot Cajun Chicken Pasta
This pasta is already rich and filling, so simple sides work best. Try it with garlic bread, a crisp green salad, roasted broccoli, steamed green beans, or roasted asparagus.
For something fresh, a tomato and cucumber salad is a nice contrast to the creamy Cajun sauce.

Leftovers and Storage
Let leftovers cool, then transfer them to an airtight container. Refrigerate for up to 3–4 days.
The pasta will continue absorbing sauce in the refrigerator. When reheating it, add a splash of milk, heavy cream, or chicken broth. Reheat gently until hot throughout.
You can freeze it for up to 2 months, but cream sauces and cooked pasta can change texture after freezing. Refrigerated leftovers have the best texture.
FAQ
Can I put uncooked pasta straight into the crockpot?
Yes, but only near the end. In this recipe, the 12 ounces of dry penne cook directly in the creamy sauce for about 15–25 minutes.
Can I use frozen chicken?
For food safety and more even cooking, thaw the chicken completely in the refrigerator before putting it in the slow cooker.
Is Cajun chicken pasta very spicy?
It depends on the Cajun seasoning. For a milder version, use less seasoning or choose a mild Cajun blend.
Why is my sauce too thick?
The pasta absorbs liquid as it sits. Stir in chicken broth, milk, or heavy cream a little at a time until the sauce reaches the consistency you like.
Why is my sauce thin?
Give the pasta and sauce a few minutes to sit uncovered after cooking. The sauce will thicken as it cools slightly. Freshly grated Parmesan can also help.
Can I use chicken thighs?
Yes. Boneless, skinless chicken thighs are a great substitute and stay juicy in a slow cooker.
Can I cook the pasta separately?
Absolutely. Boil it until al dente, drain it, and stir it into the finished sauce. If you do this, you may need less broth because the pasta won’t absorb liquid from the crockpot.

Crockpot Cajun Chicken Pasta brings tender chicken, creamy sauce, Cajun spices, and comforting pasta together with surprisingly little hands-on work. Once you see how easy that creamy sauce comes together in the slow cooker, this may become one of those recipes you keep coming back to.
