Pat wings dry, season lightly with salt and pepper, and toss with oil.
Arrange wings on a baking sheet and roast at 425°F (220°C) for 30–35 minutes, flipping halfway, until crisp.
Whisk orange juice, miso, soy, honey, vinegar, ginger, garlic, and sesame oil in a small saucepan.
Simmer glaze over medium-low heat 4–6 minutes until slightly thickened. Taste and adjust seasoning.
Toss roasted wings in warm glaze or brush glaze onto wings, then broil 1–2 minutes for a sticky finish.
Garnish with sesame seeds and scallions before serving.
