The Art of French Onion Short Rib Soup
The key to great French onion soup is slow caramelization of the onions until they’re deeply sweet and golden. Braising short ribs adds rich beef flavor to the broth, while layers of toasted bread and melted Gruyère create a hearty, indulgent finish. Simmering time lets the flavors meld beautifully.
Step-by-Step Instructions
1. Brown the Short Ribs
Season short ribs with salt and pepper.
In a large pot or Dutch oven, brown the short ribs on all sides in butter or oil.
Remove and set aside.
2. Caramelize the Onions
In the same pot, add more butter or oil if needed.
Add thinly sliced onions and cook over medium-low heat until deeply caramelized (30–40 minutes), stirring often.
3. Add Garlic & Deglaze
Add minced garlic and cook briefly.
Deglaze with white wine or a splash of broth, scraping up browned bits.
4. Add Broth & Short Ribs
Return the short ribs to the pot.
Add beef broth or stock, Worcestershire sauce, and herbs.
Bring to a simmer.
5. Simmer
Cover and simmer 2–3 hours, until short ribs are fall-apart tender.
Remove short ribs, shred the meat, and return it to the soup.
6. Prepare Gruyère Toasts
Preheat the oven broiler.
Place bread slices on a baking sheet.
Optional: spread a thin layer of Dijon mustard.
Top each with shredded Gruyère.
Broil until cheese is melted and golden.
7. Serve
Ladle hot soup into bowls.
Top each bowl with a piece of Gruyère toast or serve on the side.
Tips for Best Results
- Caramelize onions slowly — this builds depth of flavor.
- Use good-quality beef broth for rich, savory results.
- Deglaze the pot to lift flavorful browned bits.
- Shred short-rib meat finely so it disperses through the soup.
- Keep an eye on the broiler — cheese melts fast.
Creative Variations
- Herb Infusion: add rosemary or sage with thyme.
- Red Wine Broth: use red wine instead of white for deeper flavor.
- Gruyère & Thyme: add fresh thyme on toast before broiling.
- Balsamic Boost: add a splash of balsamic for tangy depth.
- Onion Blossom: add a mix of sweet and red onions for complexity.
Storage & Freshness
Store leftover soup in the refrigerator for up to 3 days; reheat gently on the stove.
