Ingredients
  

Recipe Ingredients
  • 1 lb Fettuccine pasta 450g
  • 1.5 lbs Chicken breasts 680g, boneless/skinless
  • 3 tbsp Cajun seasoning 45ml
  • 2 cups Heavy cream 480ml
  • 1.5 cups Parmesan cheese 150g, freshly grated
  • 4 tbsp Unsalted butter 56g
  • 1/4 cup Fresh parsley Finely chopped
  • 1 tsp Red pepper flakes To taste

Equipment

  • 1 Large Skillet For searing chicken and making sauce.
  • 1 Pasta Pot For boiling fettuccine.

Method
 

Preparation
  1. Boil fettuccine in salted water according to package directions. Reserve 1 cup of pasta water and drain.
  2. Pat chicken breasts dry and coat generously with Cajun seasoning on both sides.
  3. In a skillet over medium-high heat, melt 2 tbsp butter. Sear chicken for 5-6 minutes per side until a dark reddish-brown crust forms. Remove and let rest, then slice diagonally.
  4. In the same skillet, melt remaining butter and add garlic. Pour in heavy cream, scraping up the bits from the pan. Whisk in Parmesan until thick and pale-orange.
  5. Toss pasta in the sauce. Top with chicken slices, fresh parsley, and red pepper flakes.

Notes

Always use freshly grated Parmesan for a smooth sauce.
Ensure the chicken is dry before seasoning to get the best crust.
