French Onion Chicken caramelized onions under melted gooey cheese all atop braised tender chicken with a French onion style sauce. An excellent option for dinner. This soup is simple to make after work. My husband thinks it is as good if not better than any weve ever had in a restaurant. Set aside. To serve, turn on the oven broiler. Ladle the soup into ovenproof bowls. Place 1 or 2 pieces of the croutons on top of each serving of soup, depending on the size of the bowl. Place a thick slice of cheese on top of each bowl, then place the bowls on a baking sheet and broil just long enough for the cheese to become melted, bubbly and slightly toasted. Serve immediately.
