Don’t forget the aromatics: garlic, black pepper, and thyme. They layer the flavors and enhance the natural sweetness of the onions. For an extra touch, a small amount of sugar or honey can intensify the caramelization—but use sparingly, so the sweetness doesn’t overpower the dish.
Master the onions, and you’ve mastered the bake. With this foundation, your French Onion Chicken Bake becomes a comforting centerpiece for any meal.
