This leftover prime rib French dip sandwich is an easy-to-make hearty and full-flavored use of your leftover prime rib roast! Add your prime rib to some toasted rolls alongside leftover au jus for an easy and quick lunch. Not only is it simple to whip up, but it's completely delicious!
In a saucepan, bring leftover prime rib au jus (or red wine au jus) to medium temperature.
In a large skillet or frying pan, add olive oil and bring to medium high heat. Add sliced leftover prime rib beef and season with course ground salt and pepper. Cook until warmed, about 4-5 minutes.
Ladle about 1/2 cup portion of the au jus into the pan, and add the tbsp of butter.
