For Alfredo Sauce

  • 4 tablespoon unsalted butter
  • 1 tablespoon minced garlic
  • 1 cup heavy whipping cream
  • cups freshly grated parmesan cheese, (at room temperature)

To serve:

  • chopped tomatoes
  • chopped green onion
  • a sprinkle of cajun seasoning


  • Pound chicken breasts to an even thickness (between ¼ to ½-inch).
  • Place the chicken pieces in a large Ziploc bag then season with cajun seasoning, salt, and oil. Marinate for 15-30 minutes in the fridge.
  • Preheat the grill pan for 3 minutes or until hot. Lightly grease the pan with oil or cooking spray.
  • Grill the chicken breast for 3 minutes, undisturbed. Flip and cook for 3 minutes or longer, until no longer pink and the internal temperature registers at 165°F.
    Transfer the chicken to a plate and let it rest.
  • Cook the pasta in salted boiling water until al dente.
  • Melt butter in a saucepan over medium heat. Add garlic and cook just until fragrant for about 30 seconds to 1 minute.
  • Gradually stir in heavy cream and lemon zest. Whisking constantly for 2 minutes or until slightly thickened.

    Add more parmesan cheese if needed and according to your liking.
  • Season with salt and pepper if necessary.
  • Stir in pasta, toss to combine. Serve with grilled cajun chicken breast, chopped tomatoes, chopped green onion, and a sprinkle of cajun seasoning.
