Prime Rib Beef Dip

READY IN: 20mins




  • In a large saucepan, mix together the Au Jus sauce, using all ingredients to taste. (I keep onion soup mix in an old spice jar to use as a seasoning) I start with 8 oz. of water, 2 teaspoons pepper, 1 tsp Worcestershire, 8 oz. Au Jus, 2 tsp soy sauce, 2 tbsp of onion soup mix and a dash of cayenne. Simmer.
  • In a skillet, melt butter then combine chopped green peppers, onions and mushrooms with black pepper. Add soy sauce and Worcestershire. Sauté on medium heat until veggies are tender crisp.
  • Slice the leftover prime rib so that it is at a 1/2 inch (or less) thickness, then set in the simmering Au Jus.
  • Cut French bread diagonally, toast pieces in toaster.
  • Spread french onion dip on both pieces (top and bottom).
  • Layer on prime rib from Au Jus.
  • Put sauteed mushroom, onion, green peppers on top of meat.
  • Cover with pepper jack cheese.
  • Broil sandwich open-faced for 2-3 minutes or until cheese is slightly golden.
  • Serve with small bowl of Au Jus for dipping.
