Ingredients
Scale
Beef and Broth
- 2 tablespoons olive oil
- 1 pound beef short ribs
- 6 cups beef broth
- 1 tablespoon balsamic vinegar
- 1 teaspoon fresh thyme (or 1/2 teaspoon dried thyme)
- 1 bay leaf
- Salt and pepper, to taste
Vegetables and Aromatics
- 4 large onions, thinly sliced
- 4 cloves garlic, minced
Toppings
- 4 slices French bread
- 1 cup shredded Swiss or Gruyère cheese
- 2 tablespoons olive oil (for toasting bread)
Instructions
- Heat olive oil: Heat 2 tablespoons of olive oil in a large pot over medium heat, preparing the base for browning the beef.
- Sear the beef short ribs: Season the short ribs generously with salt and pepper. Sear them in the hot pot until browned on all sides, about 4-5 minutes per side. Remove the browned ribs and set them aside.
- Caramelize the onions: In the same pot, add the thinly sliced onions. Cook, stirring occasionally, until they become deeply caramelized and golden brown, approximately 15-20 minutes. This develops the rich onion flavor essential for the soup.
- Add garlic: Stir in minced garlic and cook for 1-2 minutes until fragrant, being careful not to burn it.
- Add short ribs and liquids: Return the seared short ribs to the pot. Pour in the beef broth, then add balsamic vinegar, fresh thyme, bay leaf, and season with additional salt and pepper to taste.
- Simmer the soup: Bring the mixture to a boil. Reduce the heat to low, cover, and let it simmer gently for 1.5 to 2 hours until the beef is very tender and the flavors meld beautifully.
- Toast the bread: Preheat the oven broiler. Place the French bread slices on a baking sheet, lightly brush them with olive oil, and toast under the broiler until golden and crisp.
- Shred the beef: Remove the short ribs from the soup. Shred the tender meat away from the bones and discard the bones. Return the shredded beef to the pot with the soup.
- Assemble the soup bowls: Ladle the hot soup into oven-safe bowls. Place a toasted bread slice on top of each bowl and generously sprinkle with shredded Swiss or Gruyère cheese.
- Broil to finish: Place the bowls under the broiler for 2-3 minutes until the cheese is melted, bubbly, and golden brown. Serve hot immediately for the best flavor and texture.
Notes
- Use Swiss or Gruyère cheese for authentic French onion flavor; other melting cheeses can be used in a pinch.
- Caramelizing onions slowly is key to developing sweetness and depth of flavor in the soup.
- Searing the short ribs locks in juice and adds richness to the broth.
- Broiling the cheesy bread topping adds a deliciously crispy and melty contrast to the soup.
- This soup can be prepared in advance and reheated gently before broiling the topping.
