How to Make French Onion Beef Short Rib Soup Step by Step

Step 1: Sear the Short Ribs

Heat olive oil in a large pot over medium heat. Season the short ribs with salt and pepper, then sear them until browned on all sides. This step builds a rich flavor base.

Step 2: Caramelize the Onions

Remove the ribs and add the sliced onions to the same pot. Cook slowly, stirring occasionally, until they become soft, golden, and deeply caramelized.

Step 3: Add Garlic

Stir in the minced garlic and cook briefly until fragrant, enhancing the depth of the soup.

Step 4: Build the Broth

Return the short ribs to the pot and pour in the beef broth. Add balsamic vinegar, thyme, bay leaf, salt, and pepper.

Step 5: Simmer Until Tender

Bring the soup to a gentle boil, then reduce the heat and let it simmer covered for 1½ to 2 hours, until the meat is tender and flavorful.

Step 6: Shred the Beef

Remove the ribs, shred the meat, and discard the bones. Return the shredded beef to the soup and stir well.

Step 7: Prepare the Topping

Toast slices of French bread in the oven until lightly crisp.

Step 8: Broil and Finish

Ladle the soup into oven-safe bowls, top with toasted bread and cheese, and broil until the cheese is melted, bubbly, and lightly golden.
