- 1 tablespoon Worcestershire sauce
- 1 teaspoon salt (adjust to taste)

How to Make French Onion Beef Short Rib Soup (Step-by-Step)
1. Sear the Short Ribs
Heat olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Pat the short ribs dry and season generously with salt and pepper. Sear on all sides for 3–4 minutes per side until golden brown. Remove and set aside.
2. Caramelize the Onions
In the same pot, reduce the heat to medium. Add the sliced onions and a tablespoon of butter if needed. Stir frequently, cooking for 25–30 minutes until the onions become deeply golden and caramelized. Add a pinch of brown sugar to enhance the color and sweetness.
3. Add Garlic and Tomato Paste
Stir in minced garlic and tomato paste, cooking for 1 minute to develop flavor.
4. Deglaze the Pot
Pour in the red wine (if using) and scrape up any browned bits from the bottom of the pot. Let it simmer for 2–3 minutes until slightly reduced.
5. Add Broth and Seasonings
Return the short ribs to the pot. Add the beef broth, bay leaves, thyme, and Worcestershire sauce. Stir well, cover, and bring to a gentle simmer.
6. Slow Simmer Until Tender
Reduce heat to low and simmer for 2½ to 3 hours, until the short ribs are fork-tender and falling off the bone. Skim off excess fat as it cooks.
7. Remove and Shred the Meat
Once cooked, remove the short ribs and discard the bones. Shred the beef into bite-sized pieces, then return it to the pot. Stir and taste, adjusting seasoning if necessary.
8. Toast the Bread
Preheat your broiler. Arrange baguette slices on a baking sheet, brush lightly with olive oil, and toast until golden brown.
9. Assemble the Soup Bowls
Ladle the soup into oven-safe bowls, top each with a toasted baguette slice, and sprinkle generously with Gruyère or Swiss cheese.
10. Broil and Serve
Place the bowls under the broiler for 2–3 minutes, until the cheese is melted and bubbly. Garnish with parsley or thyme and serve hot.
