Preheat your oven to 375°F (190°C).
In a bowl, whisk together honey, Dijon mustard, olive oil, garlic powder, salt, and pepper.
Place chicken breasts in a baking dish.
Pour the honey mustard mixture over the chicken, ensuring it's well coated.
Cover the baking dish with foil to retain moisture.
Bake in the preheated oven for 20 minutes.
Remove the foil and bake for an additional 5 minutes to caramelize the glaze.
Check that the chicken is cooked through (internal temperature should be 165°F or 75°C).
Let the chicken rest for a few minutes before slicing.
Garnish with fresh parsley and serve.
