Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Boneless, skinless chicken breasts or thighs
Cajun seasoning
Garlic cloves, minced
Heavy cream or half-and-half
Cream cheese
Parmesan cheese, grated
Chicken broth
Olive oil or butter
Salt and pepper
Fettuccine or pasta of choice
Fresh parsley (optional, for garnish)

Directions

Season the chicken breasts generously with Cajun seasoning on both sides.
In a skillet, heat olive oil or butter over medium-high heat and lightly brown the chicken for 2-3 minutes per side to lock in flavor (optional but recommended).
Place the chicken in the slow cooker. Add minced garlic, chicken broth, cream cheese, and heavy cream around the chicken. Stir gently to combine.
Cover and cook on low for 4-6 hours or on high for 2-3 hours until the chicken is cooked through and tender.
Remove the chicken from the slow cooker and shred it using two forks. Return the shredded chicken to the slow cooker.
Stir in the grated Parmesan cheese until the sauce is creamy and smooth. Adjust seasoning with salt and pepper.
Meanwhile, cook the fettuccine or your preferred pasta according to package instructions. Drain and toss with the Cajun chicken Alfredo sauce.
Serve hot, garnished with fresh parsley if desired.

Servings and Timing

This recipe serves about 4 people. Prep time is around 10-15 minutes, with slow cooker cooking time between 2-6 hours depending on the heat setting. It’s perfect for setting up in the morning and coming home to a ready-made meal.

Variations

I sometimes swap chicken thighs for breasts if I want a juicier texture.
For a lighter version, I use half-and-half instead of heavy cream.
Adding sautéed bell peppers and onions gives it extra color and flavor.
If I want more heat, I add a pinch of cayenne pepper or extra Cajun seasoning.
I’ve also made it with shrimp instead of chicken for a seafood twist.

Storage/Reheating

Leftovers keep well in an airtight container in the fridge for up to 3 days. When reheating, I add a splash of cream or milk to loosen the sauce and warm it gently on the stove or in the microwave to keep the texture smooth and creamy.

FAQs

Can I use frozen chicken for this recipe?

Yes, but I recommend cooking it on the low setting for 6-8 hours to ensure it cooks thoroughly.

What type of pasta works best with this sauce?

Fettuccine is classic for Alfredo, but I also like penne or rigatoni because they hold the sauce well.

Can I make this recipe dairy-free?

You can substitute heavy cream with coconut milk and use dairy-free cream cheese and Parmesan alternatives, but the flavor will be different.

How spicy is this dish?

The spice level depends on the Cajun seasoning you use. I like mine moderately spicy but you can adjust by using less seasoning or adding more for extra heat.

Can I prepare this in advance?

Definitely. I often prep the ingredients the night before and start the slow cooker in the morning, making it very convenient.
