Spare Spoons Kitchen
A sweet-savory soy, garlic, lemon, and herb marinade for chicken thighs — let them soak, then grill or oven-bake. Five minutes of stirring, and the marinade does the rest while you go about your day. (For the method on its own — oven, grill, or skillet — see Chicken Thighs, Any Way.)
Doneness: thighs are forgiving — pull them at 175°F for tender, juicy dark meat (breast wants less, but thighs love the extra few degrees). See the Kitchen Notes on chicken doneness.
This is the flavor, not the method. The two cooking routes above are the short version — for the full treatment, including a skillet method, the two-zone grill fire that stops fatty thighs flaring up, and how to get skin genuinely crisp, see Chicken Thighs, Any Way. The timings don't change when they're marinated. Don't salt them twice, though: this marinade is already a full 1% seasoning — 3 tablespoons of soy sauce is about 7 g of salt on its own, and there's another 6 g of kosher salt in the bowl — so if you're following the method page, leave its salt out entirely.
Mind the sugar. Brown sugar is what gives the lacquered, caramelized edges — and what burns if the heat's too high. Medium grill, oiled grates, and a cooler zone are the whole trick.
Don't reuse the raw marinade as a sauce. If you want a glaze, set a few spoonfuls aside before the chicken goes in, or boil the used marinade hard for a full minute first.
Boneless thighs cook faster — about 4–5 minutes a side on the grill, or 20–25 minutes in the oven; still pull at 175°F.
Works on chicken pieces of any kind, and on pork chops too.
Gluten-free: use tamari (or a gluten-free soy sauce) in place of regular soy. Everything else is already gluten-free.
Dairy-free: it already is. Lower-sugar: halve the brown sugar — you'll lose some caramelization but keep the savory backbone.
