Heat a nonstick pan, grill pan, or outdoor grill over medium-high heat. Coat the grill grates or pan with about a teaspoon of oil so that the chicken doesn’t stick. Sear or grill the chicken on each side until golden, crispy, and cooked through (about 5 minutes per side for small, thin chicken breasts, up to 10-12 minutes per side for larger, thick chicken breasts, or about 6-7 minutes per side for chicken thighs). The meat is done when it reaches an internal temperature of 165°F. Allow the chicken to rest for about 5 minutes before slicing and serving.
