Can I use chicken breasts instead of thighs?
Yes. Use boneless, skinless breasts cut into large pieces (about 2-inch chunks) so they do not dry out. Start checking at 15 to 18 minutes, depending on size. Pull at 160 to 165°F and let rest 3 to 5 minutes (it will finish cooking as it rests).
Do I need to marinate?
Nope. The sauce is strong enough that it still tastes like you planned ahead. If you do have time, 30 minutes in the fridge helps the garlic and ginger really sink in.
My sauce looks thin. What happened?
Different sheet pans and chicken sizes throw off how much liquid renders. Also, a crowded pan steams instead of reducing. If it is thin, pour the pan juices into a small saucepan and simmer 3 to 6 minutes until glossy. Or add a quick cornstarch slurry (see Tips). Just remember: reducing concentrates salt, so taste before going too far.
Is this very salty?
It is boldly seasoned, but not harsh if you use low-sodium soy sauce. If you only have regular soy sauce, start with 1/4 cup plus 1 tablespoon water, then adjust to taste. If you plan to reduce the pan juices, keep the soy a little lighter since reduction concentrates everything.
What can I serve with it besides rice?
Noodles, quinoa, roasted sweet potatoes, or even a simple cucumber salad to keep things fresh and crunchy.
Do thighs need to be exactly 165°F?
165°F is the food-safe minimum. Thighs are also great at 175 to 190°F, where they get extra tender and still stay juicy.
