Start by seasoning the beef with cajun seasoning and two tablespoons of soy sauce.
Heat the oil over high heat in a Dutch oven or heavy bottom pot.
Add in half of the beef shanks and sear on both sides, this may take between 5-7 minutes per side.
Once browned, remove those shanks and place in a large bowl or plate.
Add the other half of the shanks and brown as well.
Once all of the beef has been browned, add all the meat to the pot then cover with water (8-12 cups)
Add in garlic, onion, bay leaves, and ΒΌ cup soy sauce, and beef base.
Bring broth mixture up to a simmer then place the lid on and lower the temperature to medium heat.
Cook 1-2 hours until beef is tender.
Remove meat and vegetable from the broth mixture reserving the liquid.
Discard veggies (or throw them to the chickens!)
Chop up meat and set aside.
To assemble, place desired amount of beef to a cup or bowl, ladle over broth, then garnish with spaghetti noodles, boiled egg, green onions, as well as hot sauce and additional cajun seasoning.
