How to Make French Onion Short Rib Soup with Gruyère Toast

Sear the Short Ribs

Heat olive oil in a Dutch oven over medium-high heat. Sear the short ribs on all sides until browned, then remove and set aside.

Caramelize the Onions

Add butter to the same pot and stir in the sliced onions. Cook over medium heat for 30–40 minutes, stirring frequently, until deeply golden and caramelized. Add garlic and cook for 1 more minute.

Deglaze and Simmer

Pour in red wine to deglaze the pot, scraping up browned bits from the bottom. Return short ribs to the pot, then add beef broth, thyme, bay leaf, carrots, and celery. Bring to a boil, reduce heat to low, and simmer covered for 2.5–3 hours until meat is fork-tender.

Prepare the Meat and Broth

Remove the short ribs, shred the meat, and discard the bones. For a smoother broth, strain if desired. Return shredded meat and onions to the pot and season with salt and pepper.

Toast the Baguette and Melt Cheese

Toast baguette slices, top with shredded Gruyère, and broil until cheese is bubbly and golden.

Serve

Ladle the hot soup into bowls and top each serving with a Gruyère toast. Enjoy immediately for the perfect combination of savory broth, tender meat, caramelized onions, and melty cheese.
