If using pan drippings from a roast, pour them into a fat separator or bowl, allowing the fat to rise to the top. Skim off about 1/4 cup of the fat to use for your roux. If you don’t have drippings, melt 1/4 cup butter in your saucepan over medium heat.

Add the flour to your fat (drippings or butter) in the saucepan over medium heat. Whisk continuously until the mixture forms a smooth paste (roux). Cook and stir for about 2-3 minutes until it turns a light golden brown.

Slowly pour in your beef drippings or stock while whisking vigorously to prevent lumps from forming. Start with about 1/2 cup, whisk until smooth, then continue adding the remaining liquid gradually.

Add salt, pepper, and Worcestershire sauce. If using optional ingredients like wine, onions, or herbs, add them now.

Bring the mixture to a gentle simmer (not a full boil) and cook for about 5-10 minutes, stirring occasionally. The gravy will thicken as it cooks.

If your gravy becomes too thick, add more beef stock or water, a tablespoon at a time. If it’s too thin, continue simmering to reduce, or create a slurry with 1 teaspoon cornstarch mixed with 1 tablespoon cold water and whisk it in.

Taste and adjust seasonings as needed. For extra richness, stir in a splash of heavy cream. Remove bay leaf or any herb stems before serving.

For the smoothest possible gravy, pour through a fine-mesh strainer into a serving container.
