Ultimate Au Jus Recipe

Add the butter or drippings to a skillet and melt over medium-high heat. Add the onions and garlic and cook for 3-4 minutes. Whisk in the flour until it is incorporated and simmer for 1 minute.Add the red wine and whisk constantly to prevent lumps.  Simmer for about 2 minutes (the mixture will thicken). Whisk in the beef broth and let it simmer for another 2-3 minutes until slightly thickened. Add the remaining ingredients, return the mixture to a boil, reduce the heat to a slow simmer, and simmer uncovered for another 15 minutes.  The liquid will reduce.  Add salt and pepper to taste. Pour the mixture through a fine mesh strainer.Serve the au jus immediately or refrigerate until ready to serve (reheat in microwave).
