This flavorful beef rib eye - or ribeye - roast is coated with coarse black pepper and thyme, and then it's topped with a mustard and horseradish sauce mixture. Serve with baked potatoes and tossed salad.

Use an oven probe or meat thermometer or check the roast periodically with a reliable instant-read thermometer.

Ingredients

  • 1 beef rib eye roast, about 4 pounds
  • 1 teaspoon kosher salt
  • 1/2 teaspoon coarsely ground black pepper
  • 1/2 teaspoon dried leaf thyme
  • 1/4 cup Dijon mustard
  • 2 teaspoons prepared horseradish

Steps to Make It

  1. Gather the ingredients.

  2. Heat the oven to 350 F.

  3. Line a roasting pan with foil and place a rack in the pan.

  4. Combine the kosher salt, coarsely ground black pepper, and thyme; rub over all sides of roast.

  5. Place the roast, fat side up, on the rack in the roasting pan.

  6. If using a meat thermometer or oven probe, insert it into the center of roast. Or use an instant-read thermometer to check the roast periodically.

  7. Roast the rib eye roast at 350 F for about 1 hour.

  8. Combine the Dijon mustard and horseradish; spread over the beef.

  9. Roast for 25 minutes longer, or until roast is about 135 F to 145 F (on ​an instant-read thermometer or meat thermometer) for medium rare to medium. Roast to about 150 F for medium-well.
