Creamy Blackened Cajun Chicken Alfredo Rigatoni
There’s something about a bowl of creamy pasta with smoky, spicy chicken that always feels like the perfect comfort dinner. I love making this Blackened Cajun Chicken Alfredo Rigatoni when I want something a little more exciting than classic Alfredo without adding a lot of extra work.
The chicken gets coated in bold Cajun seasoning and seared until beautifully blackened on the outside while staying juicy inside. Then I toss tender rigatoni in a rich, garlicky Parmesan Alfredo sauce that settles into every ridge and tube of pasta.
The contrast between the creamy sauce and Cajun heat is what makes this dish so satisfying. It’s hearty enough for a cozy weekend meal, but simple enough that I can easily put it together for a weeknight family dinner.

Creamy Blackened Cajun Chicken Alfredo Rigatoni
Ingredients
Method
- Cook the rigatoni. Bring a large pot of salted water to a boil. Cook the rigatoni according to package directions until al dente. Reserve about 1/2 cup pasta water, then drain.
- Season the chicken. Pat the chicken breasts dry. If they are very thick, slice them horizontally or pound them to an even thickness. Coat both sides with Cajun seasoning, smoked paprika, garlic powder, and black pepper.
- Blacken the chicken. Heat olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Add the seasoned chicken and cook for about 4–6 minutes per side, depending on thickness, until deeply browned and the center reaches 165°F.
- Rest and slice. Transfer the chicken to a cutting board and let it rest for about 5 minutes before slicing into strips.
- Sauté the garlic. Reduce the skillet to medium-low heat. Add 2 tablespoons butter and the minced garlic. Cook for about 30–60 seconds, stirring frequently, until fragrant without letting the garlic brown.
- Make the Alfredo sauce. Pour in the heavy cream and stir, scraping up the flavorful browned bits from the skillet. Let the cream gently simmer for 2–3 minutes.
- Add the Parmesan. Reduce the heat to low and gradually stir in the Parmesan until melted and smooth. Season with black pepper and add salt only if needed.
- Combine with rigatoni. Add the drained pasta to the skillet and toss until thoroughly coated. Add reserved pasta water a tablespoon or two at a time if the Alfredo sauce needs thinning.
- Finish and serve. Divide the creamy rigatoni between bowls and top with sliced blackened Cajun chicken. Garnish with parsley and extra Parmesan, if desired. Serve immediately.
Notes
- Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
- Reheat gently over low heat with a splash of milk or cream to restore the sauce’s creamy consistency.
- For less heat, reduce the Cajun seasoning or use a mild Cajun blend.
- Add sautéed mushrooms, spinach, broccoli, or bell peppers for extra vegetables.
- Chicken thighs can replace chicken breasts; cook them to an internal temperature of 165°F.
- Cajun seasoning blends vary in saltiness, so taste the sauce before adding additional salt.
- Freshly grated Parmesan gives the Alfredo sauce the smoothest texture and best flavor.
Pro Tips
- Pat the chicken dry. Removing excess moisture helps the Cajun seasoning stick and encourages a better blackened crust.
- Use a hot skillet. Let the pan heat before adding the chicken so it sears instead of steaming.
- Watch your Cajun seasoning. Some blends contain plenty of salt, so taste yours before adding extra salt.
- Cook rigatoni until al dente. Slightly firm pasta holds up better once tossed with the warm Alfredo sauce.
- Save some pasta water. A splash can loosen a sauce that becomes too thick.
- Use freshly grated Parmesan. It melts more smoothly than many packaged pre-shredded varieties.
- Keep the sauce at gentle heat. High heat can cause a cream-and-cheese sauce to separate or become grainy.
- Rest the chicken before slicing. Give it about 5 minutes so the juices stay inside the meat rather than running onto the cutting board.
FAQs
Can I use a different pasta instead of rigatoni?
Yes. Penne, ziti, fettuccine, or rotini all work well. Pasta with ridges or curves is especially good for catching the creamy sauce.
How spicy is Blackened Cajun Chicken Alfredo Rigatoni?
It has a noticeable Cajun kick, but you can easily control the heat. Use less Cajun seasoning or choose a mild blend for a gentler flavor.
Can I use chicken thighs?
Absolutely. Boneless, skinless chicken thighs stay juicy and pair especially well with bold Cajun seasoning. Just make sure they reach a safe internal temperature of 165°F.
Why did my Alfredo sauce turn grainy?
The heat was likely too high when the Parmesan was added. Reduce the heat and add freshly grated cheese gradually, stirring until smooth.
Can I make this pasta ahead of time?
You can, although Alfredo is creamiest when freshly made. Refrigerate leftovers in an airtight container and reheat gently with a splash of milk or cream to loosen the sauce.
