Ingredients

Scale

Meat

  • 3 pounds beef short ribs

Soup Base

  • 6 yellow onions, thinly sliced
  • 3 tablespoons butter
  • 2 tablespoons olive oil
  • 4 sprigs fresh thyme
  • 4 garlic cloves, minced
  • 2 bay leaves
  • 8 cups beef stock
  • 1 cup dry red wine
  • 1 teaspoon salt
  • 1 teaspoon black pepper

Toppings

  • 1 French baguette, sliced
  • 2 cups shredded Gruyère cheese

Instructions

  1. Season and Brown Short Ribs: Season the short ribs evenly with salt and black pepper. Heat olive oil in a large Dutch oven over medium-high heat. Brown the short ribs on all sides until richly caramelized. Remove ribs and set aside.
  2. Caramelize Onions: In the same pot, add butter and additional olive oil if needed. Add the thinly sliced onions and cook on low heat for 30 to 40 minutes, stirring occasionally, until the onions become deeply caramelized and golden brown.
  3. Add Garlic and Deglaze: Stir in the minced garlic and cook just until fragrant. Pour in the dry red wine to deglaze the pot, scraping up any browned bits stuck to the bottom. Allow the wine to reduce for a few minutes to concentrate the flavor.
  4. Simmer the Soup: Add the beef stock, fresh thyme sprigs, bay leaves, and return the browned short ribs to the pot. Cover and simmer gently for 2.5 to 3 hours, or until the short ribs are tender and the meat easily falls apart.
  5. Prepare Gruyère Toasts: While the soup simmers, slice the French baguette and toast the slices under the broiler until they turn golden. Sprinkle shredded Gruyère cheese on top of each slice, then return to the broiler to melt the cheese until bubbly and slightly browned.
  6. Finish and Serve: Remove thyme sprigs and bay leaves from the soup. Ladle the hot soup into bowls and top each serving with Gruyère toasts. Serve immediately while hot and enjoy.

Notes

  • For best flavor, use good quality beef stock and dry red wine.
  • Cooking the onions slowly is key to developing the signature sweet and rich flavor.
  • Be sure to remove the thyme stems and bay leaves before serving for a smooth texture.
  • The Gruyère toasts add a delightful cheesy crunch that complements the soup perfectly.
  • Leftover soup tastes even better the next day as flavors meld.
