Preheat your oven to 425 degrees
Pat your chicken dry with paper towels
Generously season the chicken with five spice and place onto a baking sheet
Roast the chicken for 30 minutes
While the chicken is roasting, combine 1/4 cup of neutral oil, 1/4 cup of rice wine vinegar, 1/4 cup of soy sauce, 2 tablespoons of brown sugar, 1 tablespoon of five spice powder and 2 finely minced cloves of garlic in a small saucepan
When the chicken has about 10 minutes of roasting time remaining, place the saucepan over medium heat and gently simmer the sauce, stirring occasionally, until it begins to reduce and thicken
Once the sauce has reduced, remove it from the heat
After the chicken skin is crisp, carefully brush the reduced sauce over the chicken and roast for another 5 minutes
Repeat this process several times or until the chicken is cooked through with an internal temperature of 165 degrees
Transfer the chicken onto a heat proof surface to rest for 10 minutes before slicing
Serve topped with the remaining glaze and garnished with sesame seeds and thinly sliced green onions
