In a small bowl, mix together the Cajun seasoning, garlic powder, onion powder, paprika, cayenne pepper, salt, and pepper.
Rub the spice mixture evenly over both sides of the chicken breasts.
Heat the olive oil in a large skillet over medium-high heat.
Add the seasoned chicken breasts to the skillet and cook for about 6-8 minutes per side, or until the chicken is cooked through and juices run clear.
Remove the chicken from the skillet and let it rest for a few minutes before slicing or serving.
Serve the Cajun chicken with your favorite sides, such as rice, roasted vegetables, or a fresh salad. Squeeze a bit of fresh lemon juice over the chicken before serving for a burst of citrus flavor.
Enjoy!
