In a large pan over high heat, add 2 tbsp oil. Season the ribs with salt and pepper on both sides. When the pan is hot, add ribs and cook both sides until they are golden brown.
In a roasting pan add onions, garlic, beef broth, water, soy sauce, granulated sugar, thyme, bay leaves and worcestershire sauce. Add ribs to the roasting pan, cover and put in the oven. Cook for about 3 hours, making sure to check on them every half an hour or so, turning them over to ensure they cook evenly. The ribs are done when they fall off the bone.
Serve on a plate and drizzle bottom of the pan juice over them.
