If using bacon, go ahead and cook.
Pat chicken dry with paper towels, and ensure it is free of moisture. Season chicken on both sides with blackened seasoning. Rub seasoning into chicken until both sides is fully coated.
Heat a cast iron skillet over medium-high heat. Add oil and butter. Once hot, add chicken. Cook chicken for 3-5 minutes on each side until an internal temperature of 165 degree is reached.
Let chicken rest on plate or cutting board for at least 5 minutes.
Serve on bun with toppings of choice.
