Preheat the oven to 375°F (190°C) and grease a baking dish.
Whisk together maple syrup, Dijon mustard, whole-grain mustard, apple cider vinegar, garlic powder, salt, and black pepper.
Arrange chicken breasts in the baking dish and pour the sauce over them, coating evenly.
Bake in the preheated oven for 25-30 minutes, basting the chicken every 10 minutes.
Remove from the oven and let the chicken rest for a few minutes before serving.
Notes
Adjust seasonings to taste and consider adding thyme or rosemary for extra flavor.
Basting the chicken with sauce helps keep it moist and evenly coated.
Allowing the chicken to rest before serving improves tenderness.
Serve with roasted vegetables, rice, or in sandwiches/wraps. The sauce can be stored in the refrigerator for up to 5 days. Reheat chicken to 165°F (74°C) before consuming.
