01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or foil.
02 - Pat chicken thighs dry with paper towels and season both sides evenly with kosher salt and black pepper.
03 - In a small mixing bowl, combine white miso paste, maple syrup, soy sauce, rice vinegar, sesame oil, minced garlic, and grated fresh ginger. Whisk until the mixture is smooth and fully blended.
04 - Arrange chicken thighs, skin side up, on the prepared baking sheet. Generously brush half of the maple-miso glaze over the chicken.
05 - Roast the glazed chicken for 20 minutes in the oven.
06 - Remove baking sheet from the oven and brush the chicken with the remaining maple-miso glaze.
07 - Return to oven and roast for an additional 15 minutes, or until chicken is cooked through to an internal temperature of 165°F and skin is deeply caramelized.
08 - Let the chicken rest for 5 minutes. Before serving, sprinkle with toasted sesame seeds and top with thinly sliced scallions.
