Chicken thighs in a braiser: three minutes skin down, then 22 minutes skin up

01Abstract

Six bone-in skin-on chicken thighs, dry brined 12 hours, were seared skin down for 3 minutes in a tallow-lined braiser at 430 °F, then roasted skin up at 200 °C for 22 minutes over 600 g of halved potatoes. Half the batch was roasted entirely skin up from raw as a control. Skin-down-then-oven thighs reached 78 °C core with crisp skin from edge to edge; the control's skin was crisp only in the top third.

02Variables

Hypothesis Skin-on chicken thighs render and crisp better when seared skin down in a braiser and finished skin up in the oven, than when roasted entirely skin up.

03Process

1. Dry brine the thighs 12 hours uncovered in the fridge, then dry them again before they go in the pan.
2. Preheat the braiser with the tallow 12 minutes to 430 °F. Lay the thighs in skin down, away from you, and do not move them for 3 minutes.
3. Turn them skin up in the same pan, set them on top of the potatoes so the skin is above the fat line, and move the pan to the 200 °C oven.
4. Roast 22 minutes without basting. The potatoes cook under the chicken in the rendered fat and need no turning.
5. Pull at 78 °C core and rest 5 minutes skin up on a rack — resting skin down on a plate steams it soft.

04Observations

• The three skin-down minutes rendered 22 g of fat per thigh and produced an even gold surface before the oven phase began.
• At 22 minutes the seared thighs had crisp skin across the whole surface; the control's skin was crisp only in the top third, soft where it had been in contact with the pan.
• Core temperatures: seared thighs 78 °C, control thighs 76 °C at the same time.
• The potatoes under the seared batch had a crisp base from the tallow and rendered chicken fat; under the control they were pale and slightly wet.
• The braiser reached 430 °F in 12 minutes against 14 for a 12 in skillet — the wider, shallower pan heats through faster.

05Conclusion

Three minutes of skin-down contact in a braiser, then skin-up in the oven, is the sequence that gives crisp skin across the whole thigh. The sear renders 22 g of fat per piece, which is the fat that then crisps the potatoes underneath, so the two things are one process, not two. Keep the skin above the fat line in the oven phase or it will fry on one side and steam on the other.
