4.9 from 12 reviews

A rich and comforting French Onion Beef Short Rib Soup that combines tender, fall-off-the-bone beef short ribs with deeply caramelized onions in a savory beef broth, topped with toasted baguette slices and melted Gruyère cheese for an indulgent, savory finish.

Ingredients

Scale

For the Soup:

  • 2 lbs beef short ribs (bone-in for maximum flavor)
  • 3 large yellow onions, thinly sliced
  • 4 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 3 garlic cloves, minced
  • 6 cups beef broth
  • 1 tablespoon Worcestershire sauce
  • 1 bay leaf
  • 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
  • Salt and pepper, to taste

For the Topping:

  • 6 slices baguette or crusty bread, toasted
  • 1 1/2 cups shredded Gruyère or Swiss cheese

Instructions

  1. Sear the Beef Short Ribs: Heat olive oil in a Dutch oven over medium-high heat. Season the short ribs with salt and pepper, then sear on all sides until browned, about 3-4 minutes per side. Remove and set aside.
  2. Caramelize the Onions: Lower heat to medium and add butter to the pot. Add the sliced onions and cook, stirring occasionally, for 25-30 minutes until golden and caramelized. Stir in minced garlic and cook for an additional 1-2 minutes.
  3. Build the Soup: Return the short ribs to the pot with beef broth, Worcestershire sauce, bay leaf, and thyme. Bring to a simmer, then reduce heat to low, cover, and simmer for 2-3 hours until short ribs are tender and falling off the bone. Remove short ribs, shred the meat, discard bones, and return meat to the pot.
  4. Prepare the Topping: Preheat broiler. Ladle the soup into oven-safe bowls, place a slice of toasted baguette on each, and sprinkle generously with shredded Gruyère cheese. Broil for 2-3 minutes until cheese is melted and bubbly.
  5. Serve and Enjoy: Carefully remove from the oven and serve hot, garnished with fresh thyme if desired.

Notes

  • Use bone-in short ribs for deeper flavor.
  • Caramelizing onions slowly is key for a rich, sweet base.
  • Gruyère cheese provides the classic nutty melt perfect for topping.
  • For extra depth, deglaze the pan with a splash of dry white wine before adding broth.
  • Soup can be prepared a day ahead and reheated gently.
