What are the steps to cooking a boneless prime rib?

Answer 1

You can cook it as a Prime rib, fat and all, in a large roaster at 350F(190C) for about 1 hour 20 minutes with an inch (2.5 cm) of water in the roaster and the ribs on a rack, not in the water. The drippings can be separated, removing the fat and the remainder boiled down with a few herbs (thyme, parsley and black peppercorns) and salt to make an au jus. [strain out the herbs]

or it can be "frenched" (remove fat and membranes from around the bone ends)

cover the bone ends with foil to keep from burning them. Cook in the same manner as above.

or this could be made into a crown roast, slice the meat between the bones about 1/2" deep vertically then roll the roast into a crown with the bones on the outside and tie with a trussing cord. cover the bones with foil and roast as above.

A 4 pound roast might however be too small to make a crown.

Answer 2

First you need to prepare the meat but checking the size and weight of it. Add any seasonings or herbs you wish on the outside of it then bag it or put it in a roaster. Not all boneless prime rib will be completely boneless so it helps to feel the meat to check for bones that could be splintered. A meat thermometer should be used to check the core temperature to prevent it from being undercooked or overcooked.
