Chicken Alfredo Pasta Ingredients

(Full ingredient quantities appear in the recipe card below.)

• Blackened seasoning mix: smoked paprika, oregano, onion powder, garlic powder, cayenne, dried thyme and basil, black pepper, and kosher salt. Making your own blend delivers the best flavor.
• Chicken tenderloins or boneless skinless chicken breasts—tenderloins cook quickly and stay juicy.
• Seasonings for the sauce: cajun seasoning, Herbs de Provence (or Italian seasoning), and a pinch of red pepper flakes for background heat.
• Chicken bouillon paste or concentrated broth for depth of flavor in the sauce.
• Parmesan cheese for richness and to thicken the Alfredo.
• Fettuccine is the classic choice, though linguine, penne, or rigatoni also work—pick a shape that holds sauce.

Substitutions and Variations

• Swap pasta shapes: penne, linguine, or angel hair are all suitable. Short shapes like penne and rigatoni work well if you prefer bite-sized pieces with sauce trapped inside.
• Use boneless, skinless chicken breasts if preferred—slice thinner or pound to even thickness so they cook evenly and stay moist.
• Add roasted vegetables like broccoli or asparagus for color and balance.
• For a lighter version, use evaporated milk or a milk + cornstarch slurry instead of heavy cream (see FAQs for details).

How to make Blackened Chicken Alfredo

Step 3: Cook fettuccine in a large pot of salted boiling water until al dente. Reserve 1/2 cup of pasta water, then drain the noodles.

Step 6: Slice the rested chicken into bite-size pieces and fold into the Alfredo sauce. Toss the fettuccine with the sauce until evenly coated, plate, and garnish with extra Parmesan and parsley.

Pro Cooking Tips

• Pat the chicken dry so the seasoning adheres and you get a good char.
• Preheat the pan so the chicken sears quickly and seals in juices.
• Let the chicken rest for 5 minutes before slicing to retain moisture.
• Use freshly grated Parmesan for the creamiest, smoothest sauce.
• Reserve pasta water — a small splash helps loosen the sauce and helps it cling to the noodles.
• Toss pasta with sauce before plating so every bite is saucy and balanced.

Sides for Chicken Alfredo

Keep sides light to balance the richness: roasted broccoli, a simple house salad, or a crisp Caesar are great choices. For a more indulgent meal, serve with garlic bread or roasted green beans. A chilled glass of white wine pairs naturally with the creamy sauce.
