French Onion Soup

Recipe Type


  • l lb. yellow onions, sliced ¼-inch into half circles
  • 2 Tbsp. unsalted butter
  • ½ Tbsp. all-purpose flour
  • ¼ c. apple cider.
  • 3 c. beef stock
  • Pinch dried thyme
  • Salt and freshly ground black pepper to taste
  • Small French baguette, sliced crosswise into 1/2-inch pieces
  • 4 oz. Swiss cheese, grated on the large holes of a box grater


Melt butter in a heavy pot on medium-low heat. Add onions. Spread them out in as thin a layer as possible. Cook, stirring occasionally, until the onions are golden brown, beginning to caramelize, about 1 hour. Sprinkle flour over onions, and stir to coat. Add cider, stock, and thyme, and bring to a simmer. Cook, partially covered, for about 30 minutes, to allow the flavors to combine. Season with salt and pepper to taste. Ladle soup into oven-safe serving bowls and place one slice of bread on top of each. Layer each slice of bread with ¼ cup grated cheese. Place bowls on a cookie sheet and broil in the preheated oven until cheese bubbles and browns slightly.
