Ingredients Nutrition

  • 8 lbs boneless beef rib roast, about, tied with kitchen string
  • 34 cup heavy cream
  • 1 cup sour cream
  • 1 lemon, juice of
  • salt & freshly ground black pepper, to taste
  • 12 cup freshly grated horseradish or 12 cup prepared horseradish
  • 4 tablespoons olive oil
  • 1 tablespoon finely minced garlic
  • 2 large carrots, chopped
  • 3 stalks celery, chopped
  • 1 leek, white and light green portions, chopped and rinsed well
  • 5 cups unsalted beef stock
  • 4 sprigs fresh thyme, plus
  • 1 teaspoon chopped fresh thyme

Directions

  1. Let the beef roast stand at room temperature for about 1 hour.
  2. In a nonreactive bowl, combine the heavy cream and sour cream and whisk until smooth.
  3. Add the lemon juice, salt, pepper and horseradish and whisk until blended.
  4. Cover and refrigerate until ready to serve.
  5. Position a rack in the bottom of an oven and preheat to 350°F.
  6. In a small sauté pan over medium heat, warm 2 Tbs of the olive oil.
  7. Add the garlic and fry, stirring constantly, until golden, 1 to 2 minutes.
  8. Remove the pan from the heat and immediately skim the garlic from the oil, reserving the garlic.
  9. Season the beef generously with salt and pepper and rub the fried garlic over the roast.
  10. Set the beef on a rack in a roasting pan and roast until an instant-read thermometer inserted into the center of the meat registers 125°F for very rare to rare, 1 3/4 to 2 hours; or 130°F to 135°F for medium-rare to medium, 2 1/4 to 2 3/4 hours.
  11. Transfer the roast to a carving board, tent loosely with aluminum foil and let rest for 20 minutes before carving.
  12. (The roast will continue to cook as it rests, so you can remove it from the oven 3 to 4 degrees below the desired temperature). Meanwhile, in a medium saucepan over medium-high heat, warm the remaining 2 Tbs oil.
  13. Add the carrots, celery and leek, and sauté until tender and golden, 6 to 8 minutes.
  14. Add 4 cups of the stock and the thyme sprigs, bring to a simmer and reduce the heat to low.
  15. Simmer until the liquid is reduced by half, about 1 hour.
  16. After removing the roast from the pan, set the pan over medium heat, pour in the remaining 1 cup stock and whisk to scrape up any browned bits.
  17. Pour the pan juices into the simmering broth, add the chopped thyme and simmer for 10 minutes.
  18. Strain the sauce through a fine-mesh sieve set over a bowl.
  19. Skim the fat, adjust the seasonings with salt and pepper, and transfer to a sauceboat or pitcher.
  20. Carve the beef into 1/2-inch-thick slices and pass the sauce and the horseradish cream alongside.
