Bold, smoky, and packed with Louisiana-inspired flavor, this Cajun Chicken Skillet is a one-pan dinner that comes together in just 30 minutes. Tender chicken strips are coated in Cajun seasoning and seared until golden, then combined with colorful bell peppers, onion, garlic, and a savory chicken broth sauce that ties everything together. It's the kind of weeknight meal that feels effortless to make but tastes like you spent hours in the kitchen — and the leftovers taste even better the next day.

Instructions
Slice the chicken breasts against the grain into ½-inch strips and place them in a bowl. Sprinkle the Cajun seasoning over the strips and toss until every piece is well coated.
Slice the red and green bell peppers into thin strips and cut the onion into similar-sized slices. Mince the garlic cloves finely and set all prepped vegetables aside.
Place a large skillet over medium-high heat for 1 to 2 minutes, then add the olive oil and let it heat until shimmering, about 30 seconds.
Add the seasoned chicken strips in a single layer (cook in batches if needed) and sear undisturbed for 3 to 4 minutes per side until golden-brown and cooked through to 165°F (74°C). Transfer to a plate and set aside.
Return the skillet to medium heat and add the sliced onion, cooking for 2 to 3 minutes until softened. Add the bell peppers and cook for another 3 to 4 minutes until tender but still slightly crisp.
Stir in the minced garlic and cook for about 1 minute until fragrant. Season lightly with salt, keeping in mind the Cajun seasoning is already salted.
Pour in the chicken broth and use a wooden spoon to scrape up any browned bits from the bottom of the pan. Let the broth simmer for 2 to 3 minutes until it reduces slightly into a light sauce.
Return the cooked chicken strips to the skillet and stir gently to coat everything in the sauce. Cook together for 1 to 2 minutes until the chicken is reheated through.
Remove the skillet from heat and scatter fresh chopped parsley or sliced green onions over the top. Serve immediately over rice, mashed potatoes, or with crusty bread.
Notes
Don't overcrowd the pan: Cook chicken strips in batches if needed. Crowding the pan causes steaming instead of searing and you'll lose that golden crust.
Adjust the spice level: Start with 1 tablespoon of Cajun seasoning for a milder dish and add more to taste. For extra heat, add a pinch of cayenne pepper or red pepper flakes.
Homemade Cajun seasoning: Combine 1 tsp smoked paprika, 1 tsp garlic powder, ½ tsp onion powder, ½ tsp cayenne, ½ tsp dried thyme, ½ tsp dried oregano, ¼ tsp black pepper, and ¼ tsp salt.
Chicken thighs work great: Boneless, skinless chicken thighs can be substituted for breasts — they're juicier and equally delicious. Cook time is roughly the same.
Creamy version: Stir in ¼ cup of heavy cream after adding the chicken broth for a rich, creamy Cajun sauce.
Add shrimp: Toss in peeled and deveined shrimp during the last 3 to 4 minutes of cooking for a Cajun chicken and shrimp skillet.
Storage: Store leftovers in an airtight container in the fridge for up to 4 days. The flavors deepen overnight, making this an excellent meal prep recipe.
Freezing: Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating: Reheat on the stovetop over medium heat with a splash of chicken broth to loosen the sauce and keep the chicken from drying out.
Watch the garlic: Garlic burns quickly over high heat and turns bitter. Add it after the peppers have softened and keep the heat at medium when it goes in.
