- VARIATIONS: The original Barefoot Contessa recipe added 1 tablespoon cognac or brandy substitute for the white wine. If you want to make "regular" not keto gravy then instead of xanthan gum, add 1/4 cup of flour to the butter and softened onions and stir for 2 to 3 minutes before adding the broth.
- TO MAKE AHEAD: Make the gravy recipe, let it cool completely then transfer to an air-tight container. Refrigerate up to 3 days. Reheat slowly in a crock pot on low heat or a saucepan until it is warm. Add broth or cream if needed.ย
