This classic French-inspired dish transforms simple ingredients into a luxurious dining experience. The foundation is a deeply flavorful broth made by slowly simmering thinly sliced onions in butter until they are soft and sweet, then enriched with beef broth and a hint of chicken stock. Unlike traditional gratin, this “fondue” style serves the soup in individual ovenproof bowls, each topped with a slice of toasted sourdough or French bread and a layer of Jack cheese. Under the broiler, the cheese melts into a gooey, savory cap that contrasts beautifully with the hot, aromatic soup below. Its an impressive yet straightforward meal that feels like a warm hug, ideal for date nights, holiday gatherings, or any occasion where you want to comfort and delight your guests.

Ingredients

Directions

  1. Melt the unsalted butter in a large kettle or heavy pot over medium heat.
  2. Add the thinly sliced onions and saut until they are transparent and soft, but not browned.
  3. Stir in the beef broth and chicken stock base, ensuring the base is fully dissolved.
  4. Cover the pot and let the mixture simmer gently for 2 to 3 hours to develop flavor.
  5. Remove the pot from heat and refrigerate overnight or for several hours to chill completely.
  6. Once chilled, skim and discard the solidified fat layer that forms on the surface.
  7. Reheat the soup gently over medium heat until hot, then season with white pepper to taste.
  8. Slice the Jack cheese into 12 even slices.
  9. Lightly toast the 12 slices of bread until golden and crisp.
  10. Top each toasted bread slice with one slice of Jack cheese.
  11. Ladle the hot soup into 12 individual ovenproof serving bowls.
  12. Place a cheese-topped bread slice on top of the soup in each bowl.
  13. Place the bowls under a preheated broiler for 1-2 minutes, just until the cheese is bubbly and soft but not browned.
  14. Serve immediately while hot and bubbly.
