Preheat oven to 425°F (220°C). Line a rimmed baking sheet with parchment paper.
In a bowl, whisk together soy sauce, oyster sauce, brown sugar (or honey), ginger, sesame oil, lemon juice, hoisin sauce, ketchup, garlic, and five spice powder.
Add chicken wings and toss until fully coated.
Arrange wings in a single layer on the baking sheet, leaving space between pieces.
Bake 20 minutes. Flip wings, then bake 15–20 minutes more, until browned and cooked through.
Brush wings with remaining sauce from the bowl. Bake 3–5 minutes to set the glaze.
Rest 5 minutes.
Garnish with scallions, cilantro, sesame seeds, and chili if desired. Serve hot.
