If the chicken has the tenderloins attached, remove them and reserve for another use.
Combine the flour, salt, paprika, garlic powder, onion powder, black pepper and cayenne in a shallow dish. Dredge the chicken in the mixture, pressing gently to be sure it adheres well.
Heat the olive oil in a large skillet over medium-high heat. Add the chicken and cook, turning several times, until nicely browned and no longer pink in the middle, 3 to 4 minutes per side. Allow the chicken to rest for a few minutes before serving.
