Why You’ll Love This Slow Cooker Cajun Chicken Alfredo Recipe

You know that moment when you walk in the door and the house smells like someone’s Italian-Cajun grandmother has been simmering dinner all day? That’s exactly what this recipe delivers.

Here’s why it works so perfectly for busy home cooks:

• Set it and forget it. The slow cooker does the heavy lifting while you juggle work, kids, or that one neighbor who always “drops by.”
• One-pot magic. The pasta cooks right in the sauce, soaking up every drop of Cajun-spiced goodness.
• Cajun flavors = big personality. Smoky, creamy, bold, and comforting—you get it all in one bowl.
• Family-approved. Even picky eaters can’t resist tender chicken, smoky sausage, and silky Parmesan Alfredo.

Ingredients You’ll Need

Here’s everything that goes into this crowd-pleasing Slow Cooker Cajun Chicken Alfredo Recipe:

• 1 tablespoon olive oil
• 1 pound chicken breasts
• 1 pound smoked sausage (sliced into 1–inch pieces)
• 3 cups heavy cream
• 4 cups low-sodium chicken broth
• 4 tablespoons butter
• 2 tablespoons coarse Cajun seasoning
• 2 cloves garlic, smashed
• 1 pound uncooked penne pasta
• 1/2 cup hot water
• 8 oz freshly shredded Parmesan cheese (about 2 1/2 cups)
• Kosher salt and black pepper
• Garlic powder

How to Make It (Step-by-Step)

Let’s walk through this slow cooker Cajun dream—easy, doable, and absolutely delicious.

1. Prep and Sear the Chicken

Pat your chicken breasts dry (because golden sear = flavor!) and season with salt, pepper, and a sprinkle of garlic powder.
Heat olive oil over high heat and quickly sear the chicken on both sides. No need to cook it through—the slow cooker will take it from here.

2. Build the Base

Place chicken breasts and sliced smoked sausage into your slow cooker.
Add heavy cream, chicken broth, butter, smashed garlic, Cajun seasoning, 1/2 teaspoon kosher salt, and a few generous turns of black pepper.

Your kitchen already smells amazing… and we’re just getting started.

3. Slow Cook to Perfection

Cook on LOW for 4 hours or HIGH for 2–3 hours, until the chicken reaches 165°F.

This is usually the point where I get a load of laundry done, break up an argument between siblings, or take five blessed minutes just to breathe.

4. Slice the Chicken

Remove chicken and let it cool slightly before slicing. Set aside.

5. Add the Pasta

Stir in 1/2 cup hot water and your uncooked penne pasta.
Cover and cook on HIGH for 30 minutes, or until pasta is tender but not mushy.

6. Make It Alfredo-Level Creamy

Stir in shredded Parmesan cheese until melted and silky.
Add sliced chicken back in and season with additional salt and pepper to taste.

At this point, try not to eat it straight from the slow cooker with a giant spoon. (No judgment if you do.)

Mounia’s Tips for Extra-Successful Slow Cooker Cajun Chicken Alfredo

• Pasta not cooking evenly? Give it a gentle stir halfway through so it all gets cozy in the sauce.
• Want it spicier? Swap regular Cajun seasoning for a hot version or add red pepper flakes.
• Sauce too thick? Add splashes of broth or cream. Thick sauce is basically extra comfort waiting to happen.
• Love extra cheese? Add more Parmesan at the end. Always a solid life choice.

I made this once during a week when life felt like a giant to-do list, and let me tell you—this dish saved dinner… and my sanity.
