In a medium saucepan, combine beef broth, soy sauce, Worcestershire sauce, garlic powder, and onion powder.

Place the saucepan over medium heat and heat gently without boiling.

Use a whisk to stir the mixture continuously to blend evenly.

Bring the mixture to a gentle simmer and simmer for about 5-7 minutes.

Taste the au jus and adjust the seasoning with salt and pepper.

Strain the au jus through a fine-mesh strainer into a bowl for a smoother sauce, if desired.

Serve the au jus warm alongside your roast or use it as a dipping sauce.
