01 - Preheat oven to 425°F. Line a baking sheet with parchment paper or foil and place a wire rack on top.
02 - Pat wings dry with paper towels. Toss with vegetable oil, salt, and black pepper until well coated.
03 - Arrange wings in an even layer on the rack. Bake for 35 to 40 minutes, flipping halfway, until golden and crisp.
04 - While wings bake, combine soy sauce, gochujang, honey, brown sugar, rice vinegar, sesame oil, garlic, and ginger in a small saucepan. Simmer on medium heat, stirring frequently, until slightly thickened, about 4 to 5 minutes.
05 - Transfer cooked wings to a large bowl and toss with warm Korean BBQ sauce until evenly coated.
06 - Arrange wings on a platter. Sprinkle with toasted sesame seeds and sliced green onions. Serve immediately.
