Preheat the oven to 400°F (200°C).
Prepare the glaze by mixing honey, dijon mustard, olive oil, garlic powder, salt, and pepper in a bowl.
Place the chicken thighs in a baking dish and brush them generously with the honey mustard glaze.
Let the chicken marinate for 30 minutes if time permits.
Bake the chicken for 35-40 minutes, basting halfway through with any remaining glaze.
Check the internal temperature of the chicken to ensure it reaches 165°F (75°C).
Let the chicken rest for 5-10 minutes before serving and garnish with fresh parsley.
