Cajun Chicken Fettuccine Alfredo

Step-by-Step Instructions

Cook the pasta: Bring a large pot of salted water to a boil. Cook fettuccine according to package directions until al dente. Reserve ½ cup pasta water, then drain.
Season & sear the chicken: Pat chicken dry. Generously coat both sides with Cajun seasoning. Heat oil in a large skillet over medium-high heat. Sear chicken 4–5 minutes per side until blackened and cooked through (internal temp 165°F). Remove, rest 5 minutes, then slice.
Make the Cajun Alfredo sauce: In the same skillet, melt butter over medium heat. Add minced garlic and sauté 30–60 seconds until fragrant.
Build the sauce: Pour in heavy cream and bring to a gentle simmer. Whisk in Parmesan cheese gradually until melted and smooth. Stir in Cajun seasoning, smoked paprika, and red pepper flakes.
Combine everything: Add drained pasta to the sauce. Toss to coat, adding reserved pasta water a little at a time until silky. Return sliced chicken (and any optional shrimp or sausage) to the pan and warm through.
Finish & serve: Taste and adjust seasoning. Garnish generously with chopped parsley and extra Parmesan.
