🥘Ingredient Notes

For exact amounts needed see the recipe card below

  • Boneless chicken breasts: Boneless chicken thighs work fine, too.
  • Heavy cream
  • Butter
  • Chicken broth
  • Cajun seasoning
  • Paprika
  • Garlic
  • Frozen peppers and onions: I like to use frozen veggies as a shortcut. But you can chop your own if you want.
  • Andouille sausage: Andouille sausage is a little spicy, smoky, and a lot of yum. But if Andouille feels like a fireworks show in your mouth, feel free to swap it out for a milder sausage.
  • Parmesan cheese
  • Penne pasta: Any short pasta will do. Rigatoni, farfalle, you name it!
  • Salt
  • Black pepper

🥣How to Make Slow Cooker Cajun Chicken Pasta

  3. Take the chicken out, slice it, and set it aside.
  4. Add the pasta and let it cook for 30 minutes.

🍴Serving Ideas

Let’s talk about serving up this sizzling slow cooker Cajun chicken pasta. This dish is perfect for plopping the crock pot insert down in the middle of the table and letting everyone serve themselves, family style.

This pairs wonderfully with a fresh, crunchy green salad for a side dish to balance out the rich, creamy pasta. Or, you could whip up some garlic bread or cornbread. Who doesn’t love some good crusty bread to mop up that extra sauce?

💭How to Store

Transfer the pasta into an airtight container to store your leftovers and put it in the refrigerator. It’ll stay fresh for about 3-4 days.

You can also freeze this dish. Just portion the pasta into freezer-safe containers or gallon-sized freezer bags, and you’ve got some ready-made meals for those days when you can’t muster the energy to cook. Make sure to use it within 2-3 months.

When it’s time to reheat, I find the easiest way is to pop it into the microwave. Thaw it overnight in the refrigerator if you’re working from a frozen state. Then, stirring occasionally, heat it in the microwave for a couple of minutes.

How to Reduce the Spiciness

You can easily adjust the heat of this recipe. First, switch out the Andouille for a milder sausage, like kielbasa or Italian sausage. Or leave the sausage out altogether.

Then, reduce the amount of Cajun seasoning to just 1 teaspoon. Put a bottle of Louisiana hot sauce on the table so anyone who wants to add heat can pour it on.


Be sure to check out the step by step instructions

  • Are you not a fan of Parmesan? No problem! Cheddar or Pepper jack would be equally delicious.
  • Feel free to omit the peppers and onions or use fresh ones if you have them on hand.
  • Swap the penne with any pasta you fancy. Just remember, cooking times may vary.
  • If you don’t have Cajun seasoning, you can create your own blend with common spices like paprika, cayenne pepper, garlic powder, pepper, and oregano. Or, in a pinch, use Creole seasoning since it is pretty close.
