  • Stir in 1 cup grated Parmesan cheese a little at a time, mixing until the sauce is smooth and glossy. If the sauce is too thick, add reserved pasta water a splash at a time.

  • Return the cooked chicken to the pan along with the drained pasta and any optional vegetables. Toss everything together until fully coated in sauce. Season with ½ teaspoon salt and ½ teaspoon black pepper, adjusting to taste. Let everything cook together for 2 to 3 minutes, until hot and ultra creamy.

Notes

  1. Use what you have. Chicken thighs stay juicier, but chicken breasts work well too. Just don’t overcook them.
  2. Taste your Cajun seasoning. Some blends are saltier or spicier than others. Adjust gradually so you stay in control.
  3. Reserve pasta water. A splash helps loosen the sauce and makes it cling beautifully to the pasta.
  4. Freshly grated Parmesan. It melts smoothly and keeps the sauce creamy instead of grainy.
  5. Let the sauce simmer gently. Give it a few minutes to thicken before adding the cheese.
  6. Add vegetables if you like. Bell peppers and mushrooms are great here, but this recipe is flexible.
  7. Best served fresh. Cream sauces are always at their creamiest right off the stove.
