This easy au jus recipe delivers rich, savory flavor whether you use pan drippings or butter. It’s quick to make and perfect for roast beef or sandwiches.
Start with the drippings or butter (if making without dripping):
After roasting your beef, skim off any excess fat from the drippings. A little fat left behind is perfectly fine.
To a medium saucepan over medium heat, add ¼ cup of the drippings (or use butter if you don’t have drippings)
Add optional seasonings: If you're not using drippings, go ahead and add rosemary, thyme, and garlic powder to the butter. Let them sauté for a minute or so, just until they’re nice and fragrant.
Make the roux: Sprinkle in the flour and whisk to combine. Cook for about 2 minutes, stirring constantly, so the flour loses that raw taste. You’ll end up with a smooth, golden paste.
Deglaze with wine: Slowly pour in the red wine while whisking. The mixture will look deep red or purplish at first, this is normal! Let it cook down for about 2 minutes to burn off that alcohol.
Whisk in the broth: Add half of the beef broth slowly, whisking until smooth. Then add the rest along with the Worcestershire sauce. Keep whisking so it all blends together nicely.
Simmer and thicken slightly: Bring the mixture to a gentle boil. Let it simmer (gentle bubbles) for about 5 minutes, just until it thickens a bit. You're not going for gravy, just a lightly thickened, pourable sauce.
Season: Taste your au jus and season with salt and pepper as needed.
Serve: Pour it into a dish or gravy boat and serve warm.
