Melt the butter in a saucepan over medium-low heat, being careful not to allow it to brown.
Add the flour, whisking well to ensure there are no lumps. Cook it for 2-3 minutes, until it browns, then reduce the heat to low.
Pour in the chicken stock (or beef stock) a small amount at a time, whisking constantly to ensure the roux remains smooth and lump-free. Allow the sauce to thicken slightly after each addition, then add more until you’ve used it all.
If you want to use the meat drippings, add them now in place of some of the broth, and stir well.
Add the Worcestershire sauce, whisking well. Then stir in the dried herbs and any salt if needed. Add the garlic powder, onion powder, and black pepper and whisk well (adjust the amounts to taste).
Allow the sauce to simmer for a few more minutes to thicken and slightly reduce. Then remove from the heat and enjoy!
