Ingredients
  

  • 2 tbsp olive oil
  • 4 large chicken breasts - trimmed of fat
  • 1 & ½ tbsp New Orleans Cajun seasoning
  • ½ tbsp lemon pepper seasoning
  • 1 stick butter
  • 2 tbsp minced garlic
  • 8 oz block cream cheese - softened and cubed
  • 1 pint heavy cream
  • 1 cup shredded parmesan or cheddar cheese - optional but makes the sauce extra thick and rich
  • salt, to taste - optional
  • pepper, to taste - optional

Equipment

  • cutting board
  • knife
  • Meat tenderiser
  • Freezer bag
  • Measuring cups and spoons
  • Measuring jug
  • Skillet
  • Silicone spatula
  • Whisk

Method
 

  1. Trim off any fat or stringy bits from your chicken breasts, then flatten slightly with a meat tenderiser.
  2. Add your chicken to a large freezer bag.
    Sprinkle in the Cajun seasoning and lemon pepper, then give it a shake to coat evenly.
  3. Heat olive oil in a skillet over medium heat.
    Fry each breast for about 5 minutes per side, or until golden and cooked through.
    Remove the chicken and place it on a plate, cover with foil, and let it rest while you make the sauce, to keep it moist.
  4. Using that same pan you just cooked the chicken in, melt 1 stick of butter with the minced garlic on medium heat.
    Stir constantly so the garlic doesn’t burn.
  5. Drop in the cubed cream cheese and whisk slowly as it softens.
    It will look lumpy at first but keep whisking for about 5 minutes, until it turns creamy and smooth.
  6. Slowly pour in the heavy cream while stirring. It should start to thicken into a silky sauce.
    Stir in the shredded cheese (if using) until melted and combined. Add salt and pepper to taste.
  7. While your sauce simmers, boil your pasta. Fresh egg fettuccine takes just a few minutes, so they’ll be ready around the same time.
  8. When your noodles are ready, pour the creamy Cajun Alfredo sauce over the noodles, then slice your cooked chicken and lay it on top.
    A sprinkle of extra parmesan and a little black pepper on top is all it needs - enjoy!

Notes

  • You can use store-bought Cajun seasoning, but we love the New Orleans blend for a deeper smoky flavor.
  • Try adding sautéed mushrooms or bell peppers for a veggie boost.
  • The sauce will thicken as it cools, just add a splash of cream to loosen it when reheating.
 

Storage

  • Store leftovers in an airtight container in the fridge for up to 3 days.
  • Reheat gently over low heat with a splash of milk or cream
