Broil for 4-5 minutes until the chicken starts to brown. Then turn over each piece of chicken and broil for another 4-5 minutes (time varies, see recipe notes).*
The chicken is ready when both sides look caramelized (golden brown, with a few brown spots), remove and transfer to a serving platter with the sauce in the baking pan.
*The first time you make this dish watch the timing and flip them over when you see a little bit of browning. My original recipe took 6-7 minutes to brown on each side and since then I've had to replace my stove which takes considerably less time (noted) and it takes 4-5 minutes on the first side (usually 5 minutes) and 4-5 minutes on the second side (usually 4 minutes), depending on the chicken thigh size and how long they have been out of the refrigerator.
If you have an Instant Pot or pressure cooker, I have adapted this recipe for the Instant Pot in a new recipe.
