The Art of French Onion Short Rib Soup
The secret to great onion soup is slowly caramelizing the onions until deeply brown and sweet. Short ribs enrich the broth as they simmer, adding tenderness and beefy richness. Gruyère toast at the end brings a classic cheesy crunch and turns the soup into a satisfying meal.
Step-by-Step Instructions
1. Brown the Short Ribs
Season short ribs with salt and pepper.
Brown them on all sides in oil or butter in a Dutch oven or soup pot.
Remove and set aside.
2. Caramelize the Onions
Add sliced onions to the same pot.
Cook over medium-low heat, stirring occasionally, until soft and golden brown — about 30–40 minutes.
3. Add Garlic & Deglaze
Stir in minced garlic.
Deglaze with wine or a splash of broth, scraping browned bits from the pan.
4. Add Broth & Short Ribs
Return short ribs to the pot.
Add beef broth, Worcestershire sauce, thyme, bay leaves, and pepper.
Simmer gently.
5. Braise the Short Ribs
Cover and simmer for 2–3 hours, until ribs are tender and falling off the bone.
Remove ribs, shred the meat, and discard bones and fat.
Return shredded meat to the soup.
6. Make the Gruyère Toast
Preheat the broiler.
Toast the baguette slices lightly.
Optional: spread with Dijon mustard.
Top with shredded Gruyère and broil until melted and golden.
7. Serve
Ladle hot soup into bowls.
Add Gruyère toast on top or on the side.
Tips for Best Results
- Caramelize onions slowly — that’s where deep flavor comes from.
- Use high-quality beef broth for rich taste.
- Deglaze thoroughly to get all the browned bits (flavor!).

Creative Variations
