Preheat your oven to 375°F (190°C).
In a mixing bowl, whisk together honey, Dijon mustard, olive oil, apple cider vinegar, garlic powder, onion powder, salt, and pepper until well combined.
Place the chicken breasts in the baking dish. Pour the honey mustard mixture over the chicken, ensuring each piece is well coated.
Cover the baking dish with aluminum foil to retain moisture.
Bake in the preheated oven for 20 minutes. After 20 minutes, remove the foil and continue to bake for an additional 10-15 minutes, or until the internal temperature of the chicken reaches 165°F (75°C) and the chicken is golden brown.
Remove from the oven and let it rest for 5 minutes. Garnish with fresh parsley if desired.
Serve immediately with your choice of sides.
