The Cajun seasoning is non-negotiable for authentic heat. Tony Chachere’s is the gold standard (found at most grocery stores), but any blend with cayenne, paprika, and garlic works. For the chicken, bone-in thighs can substitute for breasts if you prefer darker meat—they stay juicier. Whole Foods or butcher shops often have pre-cubed chicken for convenience, saving prep time.

Out of Cajun seasoning? Mix 1 tbsp paprika, 1 tsp garlic powder, 1 tsp onion powder, ½ tsp cayenne, and ½ tsp thyme. Heavy cream can be swapped for half-and-half (less rich but still creamy). Freshly grated Parmesan is a must—pre-shredded contains anti-caking agents that ruin the texture. No wine for deglazing? Extra chicken broth works fine.

The sauce thickens as it cools—add a splash of broth if reheating. Stores in the fridge for 3-4 days (best fresh) or freezes for 2 months. To prevent pasta from absorbing all the sauce, undercook it slightly—it’ll finish in the creamy mixture.

Step-by-Step Instructions for Cajun Garlic Butter Chicken Penne

Master this restaurant-quality dish with perfectly seasoned chicken and a velvety, rich sauce that clings to every bite.

Step 1: Sear the Seasoned Chicken

Cut the 1.5 lb boneless skinless chicken breasts into bite-sized pieces and toss them with 2 tbsp Cajun seasoning, ½ tsp black pepper, and ½ tsp salt. This aggressive seasoning ensures bold flavor in every piece. Let the chicken rest for 5 minutes to allow the spices to adhere.

Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add the seasoned chicken in a single layer, working in batches if necessary to avoid crowding. Sear for 4-5 minutes until golden brown and cooked through. Transfer to a plate and set aside.

Step 2: Create the Garlic Butter Base

In the same skillet, reduce heat to medium and melt ¼ cup unsalted butter. Add the 6 cloves minced garlic cloves and sauté for 30-45 seconds until fragrant but not browned. This prevents bitterness in the final sauce.

Stir in the remaining ¼ cup unsalted butter, ½ tsp dried oregano, and 0.25 tsp red pepper flakes. Cook for 1 minute to allow the flavors to meld. The butter should foam but not brown—this creates the perfect base for your creamy sauce.

Step 3: Build the Creamy Parmesan Sauce

Sprinkle 2 tbsp all-purpose flour over the garlic butter mixture and whisk constantly for 1-2 minutes to cook out the raw flour taste. This creates a roux that will thicken your sauce beautifully.

Slowly pour in 0.5 cup chicken broth and 1.5 cups heavy cream, whisking continuously to prevent lumps. Bring to a gentle simmer and cook for 3-4 minutes until slightly thickened. Stir in 1 cup freshly grated Parmesan cheese and continue whisking until smooth and creamy.

Step 4: Combine and Finish

Return the cooked chicken to the skillet along with any accumulated juices. Stir to coat the chicken in the sauce. Meanwhile, cook 12 oz penne pasta in salted boiling water until al dente according to package instructions. Reserve ½ cup pasta water before draining.

Add the drained pasta to the skillet and toss everything together. If the sauce is too thick, add reserved pasta water 1 tbsp at a time until it reaches your desired consistency. Taste and adjust seasoning with the remaining ½ tsp salt if needed. Serve immediately with extra Parmesan if desired.
