Preheat the Oven: Preheat your oven to 375°F (190°C).
Prepare the Sauce: In a mixing bowl, whisk together the honey, Dijon mustard, and olive oil.
Season the Chicken: Season the chicken breasts with salt and pepper.
Coat the Chicken: Place the chicken breasts in the baking dish and pour the honey mustard sauce over them, ensuring they are evenly coated.
Bake: Bake for 20-25 minutes, or until the chicken is cooked through and the internal temperature reaches 165°F (74°C). The edges should be golden brown, and the center should be firm to the touch.
Rest: Let the chicken rest for 5 minutes before serving. This allows the juices to redistribute, resulting in a more tender and flavorful Honey Mustard Chicken.
Serve: Serve immediately and garnish as desired.
Check Internal Temperature: At about 20 minutes, take the internal temperature of the thickest part of the chicken breasts.
