Begin by gathering your ingredients for the Onion Beef Rib Soup. Chop the onions and garlic, slice the carrots and celery, and cut the potatoes into cubes. Arrange everything within reach.

In a large pot or Dutch oven, heat a splash of oil over medium-high heat until shimmering. Add the beef ribs and sear them for about 5-7 minutes until browned on all sides.

Once the beef ribs are browned, lower the heat to medium and add the chopped onions and garlic. Sauté for about 3-4 minutes until the onions become translucent.

Add the sliced carrots, celery, and cubed potatoes to the pot. Stir well and cook for another 3-4 minutes.

Pour in the beef broth, ensure it covers the beef and vegetables, add thyme, bay leaves, and soy sauce. Bring to a boil, then reduce heat and simmer for 1.5 to 2 hours.

After simmering, taste the broth and add black pepper as needed. Remove bay leaves before serving in bowls.
