Equipment

  • 12-inch Cast-Iron Skillet
  • Large pot or Dutch oven
  • Heavy whisk
  • Microplane or box grater

Ingredients
  

For the Blackened Chicken

  • 1 lb boneless skinless chicken breasts butterflied or pounded to even ½-inch thickness
  • 1 Tablespoon Smoked Paprika
  • 2 teaspoons Garlic Powder
  • 2 teaspoons Onion Powder
  • 1 ½ teaspoons Dried Thyme
  • ½ to 1 teaspoon Cayenne Pepper depending on your heat preference
  • 1 teaspoon Black Pepper freshly ground
  • 1 teaspoon Kosher Salt
  • 2 Tablespoons Avocado Oil or another high-smoke-point oil

For the Silky Alfredo Sauce

  • 4 Tablespoons unsalted butter
  • 1 ½ cups Heavy Cream
  • 3 cloves Garlic finely minced
  • 1 cup Parmesan Cheese freshly grated from a block
  • ½ cup Pasta Water saved from the pot after pasta is cooked
  • Salt & Black Pepper to taste

For the Pasta

  • 8 ounces Fettuccine or other quality dry pasta
  • Directions Plain Text

Instructions
 

Step 1: Make the Blackening Rub & Season the Chicken

  • Prep the Chicken: Place your pounded chicken breasts in a shallow dish. Pat them completely dry with a paper towel—this is crucial for getting a great sear.
  • Make the Blackening Rub: In a small bowl, combine the smoked paprika, garlic powder, onion powder, thyme, cayenne, black pepper, and kosher salt. Mix until the color is uniform.
  • Season Generously: Sprinkle the spice rub evenly over all sides of the chicken breasts. Use your fingers to pat the seasoning in, ensuring every inch is coated in a thick, ruddy layer. Let it sit at room temperature for about 15 minutes.

Step 2: Cook the Pasta

  • Boil the Pasta: Get a large pot of water on the boil and salt it generously (it should taste like the sea). Add your fettuccine and cook according to the package directions to al dente.

Step 3: Sear the Chicken to Perfection

  • Preheat Your Skillet: As the pasta boils, place your cast-iron skillet over medium-high heat. Add the avocado oil and let it get hot until it shimmers, about 3-4 minutes.
  • Sear the Chicken: Gently lay the seasoned chicken breasts in the hot skillet. Let it cook for 3-4 minutes per side without moving it to form a deep, mahogany crust. Flip only once.
  • Check for Doneness: The chicken is done when a thermometer inserted into the thickest part reads 165°F. Remove it from the skillet and place it on a cutting board to rest for 5-10 minutes. Do not wipe out the skillet.

Step 4: Build the Silky Alfredo Sauce

  • Sauté the Garlic: Turn the heat down to medium-low. Add the butter and let it melt, scraping up any browned bits. Add the minced garlic and sauté for 30-60 seconds until aromatic, but not browned.
  • Add the Cream: Slowly pour in the heavy cream, whisking continuously. Let it come to a gentle simmer and thicken slightly for 2-3 minutes.
  • Add the Cheese: Turn the heat to low. Add the freshly grated Parmesan in handfuls, whisking constantly and waiting for one handful to melt before adding the next. This prevents a grainy sauce.
  • Finish the Sauce: Taste and season with salt and pepper. If the sauce is too thick, whisk in a splash of the reserved pasta water until it reaches the perfect consistency.

Step 5: Combine & Serve

  • Combine and Serve: Add the drained hot pasta directly to the skillet with the Alfredo sauce. Use tongs to toss until every strand is coated. Slice the rested chicken against the grain. Serve the pasta immediately in warm bowls, topped with the sliced blackened chicken.

Notes

- For the best "Fire" crust, use a very hot cast-iron skillet and do not overcrowd the pan.
- Resting the chicken for 5-10 minutes before slicing is essential to keep it juicy.
- For the silkiest sauce, turn the heat off before whisking in the cheese.
- Always use freshly grated Parmesan from a block. Pre-shredded cheese will result in a grainy sauce
