Preheat: Preheat your oven to 375°F (190°C).
Prepare: Place the marinated chicken breasts in a baking dish or on a baking sheet lined with parchment paper or foil.
Bake: Bake the chicken breasts for 20-25 minutes or until the internal temperature reaches 165°F (74°C).
Rest: Let the chicken rest for a few minutes before serving.
