Blackened Chicken Alfredo with Homemade Cajun Spice
This blackened chicken alfredo features seared cajun-crusted chicken over fettuccine in a rich parmesan cream sauce. A bold, restaurant-quality dinner made in 30 minutes.
This blackened chicken alfredo is the antidote to bland weeknight pasta. By dredging thin chicken cutlets in a heavy coating of smoky, spicy Cajun seasoning and searing them in a hot skillet, you get a deeply caramelized crust that cuts right through the richness of a traditional white sauce.
While many versions of cajun chicken alfredo rely on jarred sauces, we’re making a real emulsified cream sauce here with heavy cream, butter, and plenty of freshly grated parmesan. The residual heat from the blackened chicken pasta adds a subtle warmth to every bite without overwhelming the palate.
The secret to a great sear is a dry surface and a hot pan. Don't crowd the skillet, or you'll steam the meat instead of achieving that signature dark, spice-forward crust that defines this Southern-inspired classic.
Ingredients
The Blackened Chicken
- 1.5 lbs (680g) boneless skinless chicken breasts, sliced into thin cutlets
- 2 tablespoons smoked paprika
- 1 tablespoon onion powder
- 1 tablespoon garlic powder
- 1 teaspoon dried oregano
- 1 teaspoon dried thyme
- 1 teaspoon cayenne pepper (adjust for heat)
- 1 teaspoon kosher salt
- 1 teaspoon cracked black pepper
- 2 tablespoons neutral oil (avocado or vegetable)
The Alfredo Sauce & Pasta
- 1 lb (454g) fettuccine pasta
- 4 tablespoons unsalted butter
- 2 cloves garlic, minced
- 2 cups (480ml) heavy cream
- 1.5 cups (150g) freshly grated Parmesan cheese
- 1/4 teaspoon ground nutmeg
- Fresh parsley for garnish
Instructions
- 1
Boil a large pot of heavily salted water and cook the fettuccine according to package directions until al dente.
- 2
Mix the paprika, onion powder, garlic powder, oregano, thyme, cayenne, salt, and pepper in a small bowl to create the blackening rub.
- 3
Pat the chicken cutlets completely dry with paper towels and coat them generously on both sides with the spice mixture, pressing it in to adhere.
- 4
Heat the oil in a large cast-iron or heavy stainless steel skillet over medium-high heat until shimmering.
- 5
Sear the chicken for 3-4 minutes per side until the crust is dark and the internal temperature reaches 165°F (74°C); work in batches if necessary to avoid crowding.
- 6
Remove the chicken to a cutting board to rest, then wipe out the skillet to remove any burnt loose spices.
- 7
Reduce heat to medium and melt the butter in the same skillet, then sauté the minced garlic for 1 minute until fragrant.
- 8
Pour in the heavy cream and bring to a gentle simmer, whisking constantly for 3-5 minutes until slightly thickened.
- 9
Turn off the heat and whisk in the parmesan cheese and nutmeg until the sauce is smooth and glossy.
- 10
Toss the cooked pasta directly into the sauce, adding a splash of reserved pasta water if needed to loosen the consistency.
- 11
Slice the rested chicken against the grain and arrange it over the plated pasta, garnishing with fresh parsley.

Tips
- → Use a cast-iron skillet if you have one. It retains the high heat necessary to properly 'blacken' the spices without burning the meat through.
- → Do not use pre-shredded parmesan cheese in the green can or the bags. It contains cellulose that prevents it from melting smoothly, which will make your sauce grainy.
- → If the sauce feels too thick after adding the pasta, add the starchy pasta water one tablespoon at a time until it reaches a silky, coat-the-back-of-a-spoon consistency.
FAQ
How do I keep the chicken moist while blackening?
The key is using thin cutlets. They cook through quickly at high heat, allowing the spices to crust over before the interior of the meat has a chance to dry out.
Can I make blackened chicken alfredo ahead of time?
Alfredo is best served immediately as the cream and cheese can separate when reheated. If you must, reheat it slowly on the stove with an extra splash of cream or milk.
Why does my alfredo sauce separate?
This usually happens if the heat is too high when you add the cheese. Always remove the pan from the heat source before whisking in the parmesan to ensure a smooth emulsion.
