Cajun Blackened Chicken and Andouille Skillet

This one-pan Cajun skillet brings the bold, smoky flavors of New Orleans straight to your weeknight table. Blackened chicken thighs and slices of Andouille sausage simmer in a rich, dark roux sauce with the classic holy trinity of onion, celery, and bell pepper.

In just 30 minutes, you'll have a deeply satisfying dinner that tastes like it spent hours on the stove. Served over fluffy rice and topped with scallions, it's the kind of meal that makes any evening feel like a special occasion.

Cajun cooking is all about layering flavor, and this skillet delivers it in spades. The chicken gets a generous coating of Cajun seasoning, then seared until blackened and juicy. The Andouille sausage brings its signature smoky, garlicky kick, while the dark roux adds an earthy depth that defines so many Louisiana classics.

The trinity—onion, celery, and green bell pepper—cooks down in the spiced drippings, creating a sauce that clings to every bite. This is comfort food with a kick, ready in the time it takes to cook rice.

Ingredients

Why this recipe works

The method here is built around developing flavor in stages. Searing the Andouille first renders its fat and creates a fond on the bottom of the skillet—those browned bits are pure flavor.

The chicken then browns in that same fat, picking up the sausage's smokiness while its own spices blacken and caramelize. This layering means every component contributes to the final sauce, giving it a complexity that can't be achieved by simply simmering everything together.

The dark roux is the secret to the sauce's rich, nutty character. Unlike a light roux used for thickening, a dark roux is cooked until it reaches a deep brown color, which gives it a toasty, almost coffee-like flavor.

It also acts as a thickener, giving the sauce a velvety body that coats the chicken and sausage beautifully. Combined with the chicken stock, it creates a gravy that's both hearty and deeply savory—exactly what you want from a Louisiana-inspired skillet.

Notes and substitutions

The holy trinity of onion, celery, and green bell pepper is the backbone of Cajun cooking, and it's essential here. Dicing them small ensures they cook quickly and meld into the sauce. For the best flavor, use a good-quality Cajun seasoning that includes paprika, garlic, and cayenne; adjust the amount to suit your heat preference. Andouille sausage can vary in spiciness, so taste it before adding extra heat.

A cast iron skillet is ideal for this recipe because it holds heat well and creates a great sear. If you don't have one, a heavy stainless steel pan will work, but avoid nonstick for the best browning. Dark roux is available in some supermarkets, but you can also make your own by cooking equal parts flour and oil until deeply browned. Store-bought roux saves time without sacrificing flavor, making this an easy weeknight meal.

• smoked Andouille sausage: use smoked kielbasa or another smoked sausage for a similar smoky flavor.
• boneless chicken thighs: boneless, skinless chicken breasts can be used; reduce browning time to avoid drying out.
• dark roux: if dark roux is not available, make a quick roux by cooking equal parts flour and oil until deep brown, about 5 minutes.
• Cajun seasoning: combine paprika, garlic powder, onion powder, cayenne, oregano, and thyme for a homemade blend.
