Prepare blackened chicken breast (boneless, cajun / prudhomme style) (2 large boneless skinless chicken breasts (8 oz each), pounded to uniform 3/4-inch thickness, coated in melted butter and aggressive Cajun blackening spice). Spray lightly with high-smoke-point oil.

Cook & Flip

Cook for 8–10 mins. Flip at the 5-minute mark for even browning.
