Ingredients

  • 1 bone-in beef rib roast (4 to 6 pounds)
  • 1 tablespoon olive oil
  • 2 teaspoons salt
  • 2 teaspoons coarsely ground pepper
  • 2 tablespoons each minced fresh rosemary, and minced fresh thyme, optional
  • HORSERADISH SAUCE:
  • 1 cup sour cream
  • 1/4 cup mayonnaise
  • 4 tablespoons prepared horseradish
  • 1 teaspoon coarsely ground pepper
  • 1/4 teaspoon salt
  • 1/4 teaspoon Worcestershire sauce
  • Optional: warm mashed potatoes and cooked asparagus

Directions

  1. Preheat oven to 450°. Brush roast with oil; rub with salt, pepper and if desired, rosemary & thyme. Place roast, fat side up, on a rack in a shallow roasting pan. Bake, uncovered, 15 minutes.
  2. Reduce heat to 325°. Bake 2-3/4 hours or until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°), basting with pan drippings every 30 minutes. Remove roast from pan; let stand 10-15 minutes before slicing.
  3. Meanwhile, in a small bowl, combine the sauce ingredients. Serve beef with horseradish sauce and if desired, hot mashed potatoes and asparagus.
