Some ways to use leftover prime rib include carne asada, shepherd's pie and a prime rib sandwich. Cooks can use prime rib instead of other types of beef for many other recipes, including stir fry and beef stroganoff.
Prime rib is also a good option for pot pie, which bakes meat, vegetables and gravy inside of a pastry shell to create an all-in-one dish.
To make a prime rib sandwich, slice the meat thinly, and layer it on toasted sliced sub rolls. Top with desired toppings, such as home-made dijonnaise, grilled onions and cheese. Use garlic, rosemary, olive oil and salt to bring out the flavors of the ingredients.
