Cajun Chicken Pasta

This Cajun Chicken Pasta has SUPER Creamy Alfredo Sauce, perfectly seasoned chicken, and your favorite pasta. This 30 minute meal is also make-ahead and freezer friendly!


  • 1 large boneless/skinless chicken breast, equal to about 1 lb.
  • 2 tablespoons olive oil
  • Salt/Pepper
  • 1 Tablespoon Cajun seasoning
  • 6 Tablespoons salted Butter
  • 4 cloves garlic, minced
  • 2 Tablespoons all-purpose flour
  • 3 cups half and half
  • ½ cup Parmesan cheese, finely grated
  • ½ cup Romano cheese, finely grated
  • ¾ pound pasta*


  • Pro Tip: Let the grated cheese and half and half come to room temperature prior to adding to the sauce.
  • Bring a pot of salted water to a boil. As it gets up to temperature, prepare the chicken.

Sear the Chicken

  • Slice chicken breast in half lengthwise and pat dry. Season generously with Cajun seasoning and desired amount of salt and pepper.
  • Heat olive oil in a skillet over medium-high heat. Add chicken and let it sear, undisturbed, for about 5 minutes on each side, until a brown crust has formed and the chicken is cooked through. Set aside, let it rest for 10 minutes prior to slicing.
  • Add the pasta to the boiling water and cook according to package instructions. Meanwhile, prepare the sauce.

Prepare the Sauce

  • Melt butter to the same skillet over medium heat. Use a silicone spatula to scrap up any brown bits from the bottom of the pan. This will give the sauce plenty of flavor. Add minced garlic and cook for 1 minute.
  • Whisk in the flour and heat for 30 seconds. Slowly add the half and half.
  • Reduce heat to low. Gradually sprinkle in the Parmesan and Romano cheese, whisking to incorporate.
  • Add the drained pasta. Use kitchen tongs to toss and incorporate into the sauce. The sauce will continue to thicken upon standing.
  • Add the sliced chicken and toss to incorporate into the sauce allow it 1-2 minutes to heat through.
  • Remove from heat and serve with homemade garlic bread.


Optional Additions

  • 1-2 Tablespoons Hot Sauce
  • Pinch Red Pepper Flakes
  • Diced Tomatoes
  • Sausage (ground or links)
  • Shrimp
  • Bell or Jalapeno Peppers
  • Broccoli
