  • 1 lb Chicken Breasts Boneless, Skinless
  • 4 tsp Cajun Seasoning*
  • 1 tsp Salt (reduce if Cajun seasoning is salty)
  • 1 tsp Pepper
  • 1/8 tsp Red Pepper Flakes (optional)
  • 4 tbsp Butter, Salted Divided
  • 1 tsp Lemon Pepper
  • 1/2 tsp Garlic Powder
  • 3 cups Heavy Cream or Half-n-Half
  • 1 lb Penne Pasta
  • 1/2 cup Parmesan Cheese
  • 1 cup Roma Tomatoes Diced


  • In a large pot, bring 4 - 6 quarts of water to a boil. Add salt to taste (about 1 tsp). Add pasta to pot, and stir gently. Return to a boil, and cook pasta until al dente (about 9-11 minutes).
  • Meanwhile, chop chicken into bite-sized pieces.
  • In a large skillet, add 2 tbsp butter, chicken, Cajun seasoning, red pepper flakes (if using), and 1 tsp each of salt and pepper. Saute over medium heat until chicken is no longer pink (about 6-8 minutes).
  • Add remaining 2 tbsp butter, lemon pepper, garlic powder, and heavy cream. Bring mixture to a boil (about 3 minutes), and reduce heat to low.
  • Before draining pasta, add 1/2 cup of cooking water to Cajun chicken sauce. Drain pasta over a colander in the sink.
  • Add drained pasta to the Cajun chicken sauce. Remove from the heat and add Parmesan cheese. Allow to rest for 5-10 minutes to allow sauce to thicken.
  • Portion Cajun chicken pasta on serving plates. Top with tomatoes and additional Parmesan cheese. Serve!
