Salt-Encrusted Rib Roast

A rib roast is a big part of our holiday dinner traditions. We love the yellow mustard, but you can use your favorite—Dijon and others are fair game. —Rebecca Wirtzberger, Yuma, Arizona
  • Total Time
    Prep: 15 min. Bake: 2-1/2 hours + standing
  • Makes
    10 servings


  • 1 bone-in beef rib roast (about 6 pounds)
  • 1/2 cup yellow mustard
  • 3 cups kosher salt (about 1-1/2 pounds)
  • 1/2 cup water


  • Preheat oven to 450°. Place rib roast in a roasting pan, fat side up; spread all sides with mustard. In a bowl, mix salt and water to make a dry paste (mixture should be just moist enough to pack); press onto top and sides of roast.
  • Roast 15 minutes. Reduce oven setting to 325°. Roast 2-1/4 to 2-3/4 hours longer or until a thermometer inserted in beef reaches 135° for medium-rare; 140° for medium; 145° for medium-well. (Temperature of roast will continue to rise about 10° upon standing.) Let stand 20 minutes before serving.
  • Remove and discard salt crust. Carve roast into slices.

    Superb roast beef. This is the only prime rib recipe that we use now.
