  • 1 pound boneless skinless chicken breasts
  • 1 tablespoon olive oil
  • 2 teaspoons Cajun seasoning plus more for garnish
  • 10 ounces penne pasta
  • 1 cup heavy cream
  • 2 tablespoons butter
  • 1/2 cup shredded parmesan cheese plus more for garnish
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 2/3 cup diced tomatoes
  • 2 tablespoons sliced green onions


  • Cook the pasta in salted water according to package directions.
  • Drizzle the olive oil over the chicken and season on both sides with Cajun seasoning, salt and pepper.
  • Preheat a grill, grill pan or skillet to medium high heat. 
  • Place the chicken on the grill and cook for 5-6 minutes on each side or until cooked through. Cut the chicken into slices.
  • While the chicken is cooking, make the sauce.
  • In small pot, combine the heavy cream, butter and 1/2 teaspoon salt and 1/4 teaspoon pepper over medium-high heat. Bring to a simmer and cook, stirring, until thick enough to coat a spoon, about 4 minutes.  
  • Stir the parmesan cheese into the sauce, cook until melted.
  • Toss the pasta with the sauce and arrange the chicken on top. Sprinkle with Cajun seasoning, tomatoes, green onions and shredded parmesan, then serve.
