Ingredients for Red Lobster Cajun Chicken Alfredo

Bold flavors meet creamy comfort with these pantry staples and fresh additions.

The chicken quality matters here. Boneless, skinless breasts from Whole Foods or Costco work great—look for uniform thickness so they cook evenly. For Cajun seasoning, Tony Chachere’s is a solid store-bought option (found at most supermarkets), but a homemade blend with paprika, garlic powder, and cayenne is even better. The Parmesan should be freshly grated—pre-shredded has anti-caking agents that make the sauce grainy.

Need to swap something? Chicken thighs stay juicier and handle the spice rub well. No heavy cream? Half-and-half with a little cornstarch thickens up nicely. If you’re skipping the flour, let the sauce reduce longer to thicken naturally. The parsley garnish is optional, but it adds that restaurant-quality finish (fresh dill works too if that’s what you’ve got).

Cooked pasta holds in the fridge for 3-4 days, but the sauce is best fresh—it thickens as it cools. Reheat gently with a splash of milk to loosen. The Cajun seasoning keeps for 6 months in a cool, dark place. Leftovers? They’re great for lunch the next day.

Step-by-Step Instructions for Cajun Chicken Alfredo

Here’s the method that delivers that signature spicy, creamy restaurant-style dish at home.

Step 1: Season and Sear the Chicken

Cut the boneless skinless chicken breasts into even ½-inch thick strips. Pat them dry with paper towels, then coat both sides with 2 tbsp Cajun seasoning, pressing gently so it adheres. This creates that signature blackened crust.

Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add the chicken in a single layer—don’t overcrowd the pan. Sear for 4-5 minutes per side until deeply browned and cooked through to 165°F internally. Transfer to a plate and tent with foil to keep warm.

Step 2: Build the Creamy Alfredo Foundation

In the same skillet, reduce heat to medium and melt ½ cup unsalted butter. Add 4 cloves minced garlic cloves and cook for 30-45 seconds until fragrant but not browned. Stir in 1 tbsp all-purpose flour to create a light roux—this thickens the sauce slightly.

Slowly whisk in 2 cups heavy cream and ½ cup whole milk, scraping up any browned bits from the chicken. Bring to a gentle simmer and cook for 2-3 minutes until the mixture thickens enough to coat the back of a spoon. The sauce should look velvety, not thin.

Step 3: Finish the Sauce and Combine

Reduce heat to low and stir in 1 cup Parmesan cheese until melted and smooth. Season with 1 tsp salt, ½ tsp black pepper, and ½ tsp dried oregano. Taste and adjust—you want that balance of rich, salty, and slightly spicy from the residual Cajun seasoning.

Add the cooked fettuccine pasta to the sauce, tossing to coat every strand. If the sauce seems too thick, add a splash of the pasta water. Return the chicken to the skillet, nestling it into the pasta. Let everything warm through for 1-2 minutes so the flavors meld together.

Step 4: Garnish and Serve Immediately

Sprinkle with ¼ cup chopped fresh parsley for a pop of color and freshness. The parsley cuts through the richness and adds a bright finish. Serve immediately while the pasta is hot and the sauce is at its creamiest.

Each serving should have tender, spice-crusted chicken, silky sauce clinging to the fettuccine, and that restaurant-quality presentation. The Cajun seasoning gives just enough heat to balance the creamy Alfredo without overpowering it.
