Step 1

Preheat oven to 400°F. Add chicken thighs to a large oven-safe pan.

Step 2

In a bowl, add vinegar, soy, garlic, bay leaves, dark brown sugar, and black peppercorns. Stir until sugar dissolves. Add onion slices so they’re mostly submerged in the liquid.

Step 3

Sprinkle onions throughout your pan. Then drizzle the vinegar-soy mixture over the chicken thighs.

Step 4

Roast chicken for 45-55 minutes, basting chicken thighs with the vinegar-soy mixture every 10-15 minutes. Make sure to move around onions as well, so they get some time in the sauce and some time on top of the chicken. Chicken is done when the sauce has thickened significantly, but there’s still enough to spoon on top.

Step 5

Remove bay leaves. Serve chicken thighs with spoonfuls of sauce and chopped scallions.
