Add beef broth and spices: Slowly pour in half the beef broth while stirring vigorously with a whisk. This will help prevent lumps. Once smooth and lump-free, add the rest of the beef broth, onion powder, garlic powder, beef bouillon base (if using), and bay leaf (if using).
3 cup beef broth, ½ teaspoon garlic powder, ½ teaspoon onion powder, bay leaf, 1 teaspoon beef bouillon base
