  1. Coat the chicken all over with the blackening seasoning, pressing it in well.
  2. Sear the chicken in hot oil for 5 to 6 minutes per side until a dark crust forms and it reaches 165°F per FoodSafety.gov. Rest, then slice.
  3. Cook the fettuccine in salted water until al dente, then drain.
  4. Melt the butter and saute the garlic, then pour in the cream and simmer. Whisk in the parmesan until the sauce is smooth.
  5. Toss the pasta in the sauce, top with the sliced blackened chicken, and serve.

Tips for the Best Blackened Chicken Alfredo

  • Get the pan hot so the seasoning chars into a true blackened crust.
  • Pound the chicken even so it cooks quickly and stays juicy.
  • Use freshly grated parmesan so the sauce stays silky, not grainy.
  • Save some pasta water to loosen the sauce if it thickens.
  • Rest the chicken before slicing so it stays moist.

Easy Variations

  • Penne or linguine: swap the fettuccine for your favorite pasta.
  • Extra spicy: add cayenne or red pepper flakes to the sauce.
  • Lighter: use half-and-half and a bit of pasta water instead of all cream.
  • Add veggies: stir in spinach, broccoli, or sun-dried tomatoes.
  • Shrimp swap: use blackened shrimp instead of chicken.

What to Serve With It

This rich pasta pairs well with lighter, crisp sides:

  • Garlic bread or a warm baguette
  • A crisp Caesar or green salad
  • Roasted or steamed broccoli
  • Sauteed green beans

How to Store and Reheat

Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently on the stove or in the microwave with a splash of cream or milk, stirring often, since alfredo sauce thickens as it cools. Freezing is not ideal because cream sauces can separate, so this dish is best enjoyed fresh or within a few days.
