Preheat oven to 425°F (220°C). Pat wings dry and season lightly with salt and pepper.
Toss wings with a little oil and spread on a rimmed baking sheet. Bake 35–40 minutes, flipping once, until crisp.
Meanwhile, combine honey, soy sauce, rice vinegar, sesame oil, garlic, and ginger in a small saucepan. Bring to a simmer.
Stir in cornstarch slurry and cook until sauce thickens, about 1 minute. Remove from heat.
Toss baked wings in the sticky sauce to coat evenly. Sprinkle sesame seeds and green onions before serving.
