Trim any large chunks of fat from the chicken thighs and pat them dry with paper towels.
Sprinkle half of the Chinese five-spice over the top of the thighs and rub it in. Sprinkle sea salt over that side. Flip the thighs, rub in the remaining Chinese five-spice, and sprinkle sea salt on the other side.
Heat 2 teaspoons olive oil in a large nonstick skillet over medium-high heat until the oil shimmers.
Add the chicken thighs to the hot skillet, spacing them so they aren’t crowded, and sear until the bottoms are golden brown, about 2–3 minutes.
While the first side sears, combine 1/2 cup chicken broth, 1/4 cup honey, and 1 1/2 teaspoons minced fresh ginger in a small microwave-safe bowl and whisk until blended. Microwave the mixture for 30 seconds, then whisk again.
Flip the chicken thighs, reduce the heat to low, and pour the honey-broth-ginger mixture evenly into the skillet. Cover the pan and cook until an instant-read thermometer inserted into the thickest part of a thigh reads 165°F, about 5–15 minutes depending on thickness.
Uncover and simmer on low until the sauce thickens and coats the chicken, about 3–5 minutes.
Garnish with cilantro and serve hot.
