1. Cook the soy sauce, honey, ginger, and garlic over low heat until the honey is melted.
2. Place chicken breasts, skin side down, in baking dish and pour marinade over top. Cover tightly with foil and refrigerate. Let marinate for at least 1 hour (or up to 24 hours).
3. Preheat oven to 350. Cook chicken (covered with foil) for 30 minutes. Flip chicken so it is skin-side up, raise oven temp to 375 degrees, and cook for 20 - 25 more minutes, basting occasionally. The sauce should be a dark, rich brown.
