I used to caramelize the onions on the stove top, but now I use this fantastic method. Finally, a way to make genuine French Onion Soup without all of the stirring. While it still takes quite some time, the onions are roasted in the oven. Sweet onions, such as Vidalia or Walla Walla, will make this recipe overly sweet, so use Yellow or Red, or a combo of both. Use broiler-safe crocks and keep the rim of the bowls 4 to 5 inches from the broiler to obtain a proper melting of the cheeses. Cooks Illustrated chefs prefer using Swanson Certified Organic Free Range Chicken Broth and Pacific Beef Broth, tho others will do fine as well. There is actually more flavor and depth in chicken broth than in beef and that is why they combine it with the beef broth. Much of the cooking time is passive...and the aroma makes the kitchen smell divine! For the best flavor, make the soup a day or 2 in advance, it also freezes well in 2 gallon freezer bags. Prep time includes the soup and the croutons. Cooking time is approximate, please use your judgment. I make this every Christmas Eve along with appetizers and those that missed Christmas Eve INSIST on having a bowl on Christmas morning! LOL It truly is the best French Onion Soup I have ever tasted. For those special occasions, try this one. Hope you enjoy!
