Blackened Chicken Alfredo Recipe: Cajun-Spiced Pasta with Creamy Sauce

I developed this recipe to bring bold Cajun flavors together with creamy pasta in one satisfying dish. The blackened chicken adds a smoky, spicy kick that perfectly complements the rich alfredo sauce.

This method uses a simple spice blend for the chicken and a straightforward technique for the sauce. The key is cooking the chicken hot and fast to achieve that signature char without overcooking.

You’ll end up with tender, flavorful chicken pieces nestled in a velvety sauce that clings to every strand of pasta. It’s restaurant-quality comfort food made right in your kitchen.

The dish comes together in under 30 minutes, making it ideal for weeknight dinners when you want something special without the fuss.

Ingredients for Blackened Chicken Alfredo

Pantry staples meet bold Cajun spices for this creamy pasta dish.

The chicken is the star here. Boneless, skinless breasts work best—pound them to even thickness so they cook uniformly. For the Cajun blend, Penzeys has excellent spices, but any grocery store brand works if it’s fresh. The Parmesan needs to be freshly grated from a wedge; pre-shredded has anti-caking agents that make the sauce grainy. I grab mine from Whole Foods when I want good quality without the deli counter markup.

No heavy cream? Half-and-half works at a 1:1 ratio (just slightly less rich). Swap the paprika for smoked paprika if you want deeper flavor. Short on Parmesan? Pecorino Romano adds a sharper bite. The cayenne can be reduced or omitted for milder heat. For the pasta, fettuccine is classic, but pappardelle or linguine hold the sauce just as well.

Leftovers keep 3-4 days in the fridge—reheat gently with a splash of milk to loosen the sauce. The Cajun spice blend stays potent for 6 months in a dark cabinet. I always make extra and freeze it in portions for quick weeknight meals.

Step-by-Step Instructions for Blackened Chicken Alfredo

Here’s the method. Straightforward, tested, works every time.

Step 1: Season and Blacken the Chicken

Combine the 2 tsp Paprika, 1.5 tsp Garlic Powder, 1.5 tsp Onion Powder, 1 tsp Dried Thyme, 0.5 tsp Cayenne Pepper, 1 tsp Ground Black Pepper, and 1 tsp Kosher Salt in a small bowl. This is your Cajun seasoning blend.

Pat the 1.5 lb Chicken Breasts dry with paper towels, then coat both sides generously with the seasoning mix. Heat a large skillet over medium-high heat and add 2 tablespoons of the 0.5 cup Unsalted Butter. Sear the chicken for 5-6 minutes per side until the outside is deeply browned and slightly charred—this creates that signature blackened crust. The internal temperature should reach 165°F.

Step 2: Cook the Pasta to Al Dente

While the chicken cooks, bring a large pot of salted water to a rolling boil. Add the 12 oz Fettuccine Pasta and cook according to package directions until al dente—about 1 minute less than the suggested time. You want the pasta to finish cooking in the sauce later.

Reserve ½ cup of the pasta water before draining. This starchy water is essential for adjusting the sauce consistency. Drain the pasta but don’t rinse it; the surface starch helps the sauce cling better.

Step 3: Build the Alfredo Sauce

In the same skillet used for the chicken (no need to clean it—those browned bits add flavor), melt the remaining unsalted butter over medium heat. Add the 3 cloves Minced Garlic Cloves and sauté for 30 seconds until fragrant but not browned.

Pour in the 2 cups Heavy Cream and stir, scraping up any browned bits from the chicken. Bring to a gentle simmer, then reduce heat to low. Stir in the 1.5 cups Parmesan Cheese until fully melted and smooth. If the sauce is too thick, thin it with the 0.5 cup Whole Milk until it coats the back of a spoon.

Step 4: Combine and Finish

Slice the blackened chicken into strips. Add the drained pasta to the sauce and toss to coat evenly. If the sauce clings too tightly, add reserved pasta water 1 tablespoon at a time until it reaches your desired consistency.

Gently fold in the chicken strips and let everything warm through for 1-2 minutes. The pasta should be fully tender, and the sauce should cling to every strand. Serve immediately while hot—the sauce thickens as it cools, so timing matters.
