This savory ginger chicken cooks down into a rich, deeply flavored main course. Bone-in chicken thighs simmer gently in a straightforward broth of soy sauce, water, chopped onion, and plenty of ground ginger until fall-apart tender. The slow cooking process creates a comforting sauce that begs to be spooned over a warm bowl of rice. It is an ideal hands-off dinner for busy weeknights.
