Key Ingredients

Chicken Breast
Opt for fresh, good quality chicken breasts. They form the protein base of this dish and will absorb all the flavors of the Cajun seasoning. Their tender texture perfectly contrasts with the al dente pasta.
Blackened Cajun Seasoning
The heart of this dish! A balanced blend of smoked paprika, cayenne pepper, onion powder, garlic powder, black pepper, salt, dried thyme, and dried oregano. This mixture brings heat, complexity, and that characteristic blackened crust that gives the dish its name.
Heavy Cream
It brings richness and creaminess to the Alfredo sauce. Its velvety texture perfectly coats the pasta and softens the heat of the Cajun spices.
Garlic
Essential in both Cajun and Italian cooking, fresh garlic brings essential aromatic depth to this fusion dish.
Butter
It serves both to blacken the chicken and enrich the sauce. Its nutty flavor is the pillar of any good Alfredo sauce.
Parmesan
Use freshly grated parmesan for optimal flavor. It melts into the hot sauce and adds that characteristic salty, umami note.
Mafaldine Pasta (or fettuccine/linguine)
Mafaldine, with their wavy edges, perfectly retain the creamy sauce. If you can’t find them, fettuccine or linguine will work very well. Their wide, flat texture is ideal for this type of sauce.
Pro Tips for Foolproof Juicy Chicken Breasts
- Start with quality chicken, ideally air-chilled and organic. The quality of your main ingredient will directly influence the final result.
- Take time to trim excess fat or bloody areas. This ensures even cooking and better presentation.
- Pound the chicken to a uniform 1/4 inch thickness by placing it between two sheets of parchment paper and using a meat mallet. This step is crucial for quick and even cooking.
- Generously rub the chicken with oil before applying seasonings. The oil helps spices adhere and promotes the formation of that beautiful blackened crust.
- Take the chicken out of the refrigerator about 30 minutes before cooking. Room temperature chicken cooks more evenly than cold chicken.
- Sear the chicken over medium-high heat for 3-4 minutes on each side. This high temperature is essential to get the blackened effect without overcooking the inside.
- Only flip the chicken once, then reduce the heat and add butter to finish cooking. This allows for a perfect crust while keeping the inside juicy.
Blackened Chicken VS Burnt Chicken
Don’t be misled by the term “blackened.” Blackened chicken is coated with a spice mixture that forms a dark crust during cooking, but it absolutely does not have a bitter taste like burnt chicken might have. This culinary technique, originating from Louisiana, is also commonly used for shrimp and salmon. It’s the reaction between the spices and heat that creates this characteristic color, not overcooking.
How to Make Blackened Cajun Alfredo Chicken
Step 1: Pound the chicken, season it, and blacken it in a pan
Start by uniformly flattening your chicken breasts, then generously coat them with the Cajun spice mixture. In a hot pan with a little oil, sear the chicken until it develops that beautiful characteristic blackened crust. Set aside the chicken and slice it.
Step 2: Prepare the Alfredo sauce in the same pan
Without cleaning the pan (those little stuck bits are full of flavor!), add butter and minced garlic. Sauté until the garlic is fragrant, then add the heavy cream. Let simmer for a few minutes before incorporating the grated parmesan. The sauce should thicken slightly.
Step 3: Boil the noodles and mix everything together
While your sauce is simmering, cook the pasta al dente according to package instructions. Drain them and incorporate them directly into the sauce. Add the blackened chicken slices and gently mix so that each bite is coated with this delicious creamy sauce.

- Remove the chicken from the pan and let it rest on a cutting board while you prepare the sauce and pasta.
- In the same pan, reduce heat to medium and add 4 tablespoons of butter. Once melted, add 4 minced garlic cloves and sauté for 30 seconds until fragrant.
- Pour 2 cups of heavy cream into the pan and let simmer for 2-3 minutes. Then incorporate 1 cup of freshly grated parmesan and stir until the cheese is melted and the sauce is smooth.
- Meanwhile, cook 1 pound of Mafaldine pasta (or fettuccine) in a large pot of salted boiling water according to package instructions until al dente.
- Drain the pasta and add it directly to the pan with the Alfredo sauce. Mix well to coat all the pasta.
- Slice the blackened chicken and arrange it on top of the pasta. Garnish with chopped fresh parsley and additional parmesan if desired.
