Heat a nonstick pan over medium-low (4/10) heat.
Lightly oil the pan and place the chicken skin-side down.
Immediately press down on the chicken with a heavy saucepan (~3 lbs) to prevent the skin from shrinking excessively. Allow allow the thighs to cook undisturbed under the heavy pot for 5–6 minutes
Remove the pot and continue cooking for another 4-5 minutes
Check the skin, it should be deep golden brown, not just lightly browned.
Flip the thighs and cook for 2 minutes over low heat to finish cooking through.
The internal temperature should reach 170–180°F (77–82°C).
Let the chicken rest for 5 minutes on a wire rack.
