French Onion Soup Gratinee
Why This Recipe Works
To make a better, quicker onion soup recipe, we created a "cheaters" broth with canned beef, chicken broths, and wine. We chose red onions for subtle complexity and nuance, and caramelized them for maximum flavor. To prevent the crouton in our French onion soup recipe from getting too soggy, we placed it atop the soup, so only the bottom was submerged. For the cheese—the raison d'être of French onion soup—we liked a combination of pungent Swiss topped with subdued Italian Asiago or Parmesan.
