How to Make Slow Cooker Cajun Chicken Alfredo Recipe

Step 1: Sear the Chicken

Start by patting your chicken breasts dry and seasoning them generously with salt, pepper, and a sprinkle of garlic powder. Heat olive oil in a pan over high heat and quickly sear the chicken for a couple of minutes on each side until golden brown. This not only locks in moisture but also infuses the meat with a lovely caramelized flavor that’s essential for this dish.

Step 2: Combine Ingredients in the Slow Cooker

Place the seared chicken breasts and sliced smoked sausage into your slow cooker. Pour in the heavy cream, chicken broth, add the butter, smashed garlic cloves, Cajun seasoning, salt, and black pepper. Give everything a gentle stir to combine the flavors, then cover and set your slow cooker to low for about 4 hours or high for 2 to 3 hours. The chicken will cook until tender and reaches a safe internal temperature of 165 degrees.

Step 3: Shred and Slice the Chicken

Once cooked, carefully remove the chicken breasts from the slow cooker and let them cool just enough to handle. Then, slice or shred the chicken into bite-sized pieces. This will ensure every forkful includes a generous amount of tender chicken soaking in the creamy sauce.

Step 4: Cook the Pasta in the Sauce

Stir in half a cup of hot water and the uncooked penne pasta into the slow cooker. Cover and cook on high for about 30 minutes, or until the pasta is perfectly tender. This method allows the pasta to absorb the flavorful sauce, making this dish incredibly cohesive and satisfying.

Step 5: Finish with Parmesan and Chicken

Once the pasta is cooked, stir in the freshly shredded parmesan cheese and the sliced chicken. Season with additional salt and black pepper to taste. The cheese melts into the sauce, creating a stunningly rich, creamy texture with that signature Alfredo tang, now elevated with spicy Cajun notes.

Garnishes

To brighten up the rich flavors, sprinkle some freshly chopped parsley or green onions over the top. A light dusting of extra parmesan can add an elegant touch, and if you love heat, a pinch of red pepper flakes will amp up the Cajun vibe perfectly.

Side Dishes

This dish pairs wonderfully with a crisp green salad dressed lightly with lemon vinaigrette to balance the richness. Garlic bread or a buttery baguette are also fantastic sides to soak up every last bit of that creamy sauce.

Creative Ways to Present

For a fun twist, serve the Slow Cooker Cajun Chicken Alfredo Recipe in individual white ramekins or hollowed-out mini bell peppers for a festive presentation. Drizzling a little extra Cajun oil or melted butter over the top just before serving adds a beautiful glossy finish and bursts of flavor.

Make Ahead and Storage

Storing Leftovers

Store any leftovers in airtight containers in the refrigerator for up to 3-4 days. The flavors tend to deepen overnight, making your next meal just as delicious! Give it a good stir before reheating to bring everything back together nicely.

Freezing

This Cajun Chicken Alfredo freezes well when packed into freezer-safe containers. Freeze for up to 2 months. When ready, thaw overnight in the refrigerator for best results before reheating.

Reheating

Reheat leftovers gently on the stovetop over low heat, stirring occasionally, adding a splash of milk or cream if it needs to loosen up. Alternatively, microwave in short bursts, stirring in between to keep the sauce silky smooth.

FAQs

  1. Can I use other types of pasta for this Slow Cooker Cajun Chicken Alfredo Recipe?

    Absolutely! While penne works great, other pasta shapes like rigatoni, rotini, or even fusilli can be used. Just keep in mind cooking times may vary slightly depending on the shape and size, so keep an eye on the pasta to avoid overcooking.

  2. Is it possible to make this recipe spicy or mild?

    Yes! The Cajun seasoning is where the spice comes from, so you can adjust the amount based on your heat tolerance. For extra kick, add cayenne pepper or hot sauce. To make it milder, use less Cajun seasoning or opt for a milder spice blend.

  3. Can I make this recipe ahead of time?

    You can prep the ingredients ahead and keep them ready in the fridge, but it’s best to assemble and cook the dish just before serving to ensure the pasta stays perfectly tender and creamy.

  4. What can I substitute for smoked sausage?

    If you prefer a different protein or don’t have smoked sausage on hand, try andouille sausage, chorizo, or even diced bacon for similar smoky flavors. For a lighter option, omit sausage altogether or use mushrooms for a vegetarian twist.

Final Thoughts

This Slow Cooker Cajun Chicken Alfredo Recipe is the perfect blend of creamy, spicy, and utterly comforting. Once you make it, it’ll quickly become your favorite go-to for those nights when you want something deliciously hearty without fuss. So grab your slow cooker, gather the ingredients, and treat yourself to this flavorful dish that feels like a warm hug in every bite!

Perfect for a comforting family dinner, this recipe cleverly uses a slow cooker to infuse deep flavors while keeping the kitchen hassle-free.

Ingredients

Scale

Protein

  • 1 pound chicken breasts
  • 1 pound smoked sausage, sliced into 1 inch pieces

Dairy

  • 3 cups heavy cream
  • 4 tablespoons butter
  • 8 oz freshly shredded parmesan cheese (about 2 1/2 cups)

Pantry & Seasonings

  • 1 tablespoon olive oil
  • 4 cups low sodium chicken broth
  • 2 tablespoons coarse Cajun seasoning
  • 2 cloves garlic, smashed
  • 1 pound uncooked penne pasta
  • 1/2 cup hot water
  • Kosher salt and black pepper, to taste
  • Garlic powder, to sprinkle on chicken

Instructions

  1. Season and Sear Chicken: Pat the chicken breasts dry and season them thoroughly with kosher salt, black pepper, and a sprinkle of garlic powder. Heat olive oil in a skillet over high heat, then quickly sear the chicken breasts on both sides until lightly browned to lock in flavors.
  2. Add Ingredients to Slow Cooker: Place the seared chicken breasts into the slow cooker along with the sliced smoked sausage, heavy cream, low sodium chicken broth, butter, smashed garlic cloves, 1/2 teaspoon kosher salt, Cajun seasoning, and several grinds of fresh black pepper. Stir gently to combine.
  3. Cook the Chicken and Sausage: Set the slow cooker on low and cook for about 4 hours, or on high for 2 to 3 hours, until the chicken reaches an internal temperature of 165°F and is fully cooked through.
  4. Slice Chicken: Carefully remove the chicken breasts from the slow cooker and set aside to cool slightly. Once cool enough to handle, slice the chicken into pieces.
  5. Add Pasta and Cook: Stir 1/2 cup of hot water and the uncooked penne pasta into the slow cooker. Cover and cook on high for about 30 minutes, stirring occasionally, until the pasta is tender but still firm to the bite.
  6. Finish the Alfredo: Once the pasta is cooked, stir in the freshly shredded parmesan cheese and the sliced chicken. Adjust seasoning with additional salt and black pepper to taste. Mix well to combine everything evenly and melt the cheese into the creamy sauce.

Notes

  • Use low sodium chicken broth to better control the saltiness of the dish.
  • For a spicier kick, increase the amount of Cajun seasoning or add a pinch of cayenne pepper.
  • Searing the chicken before slow cooking enhances flavor through browning.
  • Check pasta frequently during the 30-minute cooking to avoid overcooking.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated gently.
  • The dish can be made gluten-free by substituting penne pasta with a gluten-free variety.
