To make brown gravy, you can follow a straightforward method using butter, flour, and beef broth or stock as the base. Here is a simple step-by-step guide:

1. Melt butter in a saucepan over medium heat.
2. Whisk in all-purpose flour to form a roux, stirring continuously until the mixture becomes paste-like and turns light golden brown (about 3-5 minutes). This cooks out the raw flour taste.
3. Gradually whisk in beef broth or stock, adding it slowly to avoid lumps.
4. Continue to cook and stir until the gravy thickens and is smooth, about 2-3 minutes.
5. Season with salt, pepper, and optional seasonings like garlic powder, onion powder, Worcestershire sauce, or herbs to taste.
6. For a silky finish, swirl in a tablespoon of cold butter just before serving.

Alternatively, you can thicken the gravy using a slurry made from cornstarch and cold water instead of flour. In this case, you would simmer the broth with seasonings, then whisk in the cornstarch slurry and cook until thickened, finishing with butter for richness

. This basic method yields a rich, savory brown gravy perfect for serving over meats, mashed potatoes, or vegetables.
