Preheat the oven to 425 degrees F (218 degrees C).
Combine melted butter and olive oil. Brush this mix over the entire chicken, including the cavity.
Sprinkle on salt and pepper, then rub minced garlic on the chicken.
Stuff the chicken with lemongrass, garlic, and lemon.
Tie the chicken legs with butcher’s twine, ensuring it cooks evenly.
Place the chicken in the oven and bake for 1 hour and 15 minutes, basting with pan juices every 30 minutes.
While the chicken roasts, combine the glaze ingredients in a saucepan. Heat until bubbling, then set aside.
Once roasting time is complete, increase the oven to broil.
Brush the chicken with the glaze and bake for an additional 10 minutes.
Ensure the internal temperature is at least 165 degrees F (74 degrees C). If needed, return to 425 degrees F for 5-10 more minutes.
Serve the chicken with any leftover glaze.
