Easy Prime Rib with Fresh Horseradish Sauce
- serves 6
A classic main dish for entertaining and holiday dinners.
1 first-cut 3-bone prime rib roast (about 6 1/2 lbs), also called standing rib roast
⅓ cup freshly grated peeled horseradish (from about a 5-oz piece)
1 ¼ cups creme fraiche or sour cream
2 tsp white wine vinegar
½ tsp sugar
Kosher salt and freshly ground black pepper
2 bunches rosemary
2 bunches sage
2 bunches thyme
1 Tbsp olive oil
Flaky sea salt, for serving
1. Pat the prime rib dry with paper towels. Refrigerate, uncovered, for at least 1 day and up to 3 days to age the meat.
2. At least 4 hours and up to 1 day before serving, mix the horseradish, creme fraiche, vinegar and sugar together; season with salt and pepper. Refrigerate until ready to serve.
3. Preheat the oven to 225ºF. Toss the rosemary, sage and thyme with the oil, and arrange on the bottom of a roasting pan. Season the prime rib generously with salt and pepper, then set it on top of the herbs.
4. Roast until an instant-read thermometer inserted into the center of the prime rib registers 125ºF, 3 hours 15 minutes to 4 hours. Remove from the oven and let rest at least 30 minutes and up to 1 hour.
5. Increase the oven temperature to 500ºF. Right before serving, return the rested prime rib to the oven and roast until the outside is browned and caramelized, about 10 minutes.
6. Transfer the prime rib to a cutting board. Cut the meat away from the bones with a sharp chef's knife and then slice the meat across the grain.
7. Serve with the crispy herbs, horseradish sauce and flaky sea salt.
