Heat oil in a large oven-safe skillet over medium-high. Sear chicken skin side down until golden, about 5 minutes. You'll know it's ready to flip once it releases from the pan. It sticks because the
crust is still forming, so don't nudge it around if it's not releasing. The protein will almost always tell you when it's ready. Flip and cook another 4 minutes. Transfer to a plate.
