Method
- Step 1: Preheat the oven to 450°F (232°C).
- Step 2: In a small bowl, combine olive oil, kosher salt, black pepper, garlic powder, chopped rosemary, and thyme. Mix well to form a paste.
- Step 3: Generously rub the seasoning mixture all over the rib roast.
- Step 4: Position the rib roast bone side down on a rack in a roasting pan.
- Step 5: Roast the rib roast in the preheated oven for 20 minutes.
- Step 6: After 20 minutes, reduce the oven temperature to 325°F (163°C) and continue roasting until the internal temperature reaches your desired doneness.
- Step 7: Use a meat thermometer to check the internal temperature.
- Step 8: Once cooked to your liking, remove the roast from the oven and cover it loosely with aluminum foil. Let it rest for 15-20 minutes.
- Step 9: While the roast is resting, mix the sour cream, prepared horseradish, Dijon mustard, lemon juice, salt, and pepper in a bowl. Adjust the seasoning to your taste.
- Step 10: After resting, slice the rib roast against the grain and arrange it on a serving platter. Serve with the creamy horseradish sauce on the side.
Notes
Let your rib roast rest for 15-20 minutes after cooking to allow the juices to redistribute.
