Tyler Florence’s addition of horseradish and garlic to the crust adds a welcome kick, cutting through the richness and enhancing the beef’s natural flavors.
Ingredients
For the Roast
- 1 bone-in prime rib roast (3 ribs, about 6 lbs)
- 5 garlic cloves, smashed or minced
- 1/2 cup prepared horseradish
- 1/2 cup sea salt or kosher salt
- 1/4 cup freshly ground black pepper
- 1/2 cup extra-virgin olive oil
Optional Vegetables (for roasting, per video reference)
- 2 carrots, peeled and chopped
- 2 parsnips, peeled and chopped
- 1 red onion, halved
- 2 heads garlic, halved
For the Wild Mushroom Sauce (optional, per video reference)
- 2 lbs assorted wild mushrooms (cremini, oyster, shiitake, chanterelle, or white)
- 1 tbsp unsalted butter
- Extra-virgin olive oil
- Leaves from 2 fresh thyme sprigs
- Sea salt and freshly ground black pepper
- 1/2 cup Cabernet Sauvignon
- 1/4 cup reserved beef drippings or low-sodium broth
- 1/4 cup heavy cream
- 1 tbsp minced fresh chives
Equipment
- Large roasting pan
- Instant-read meat thermometer
- Fat separator (optional, for pan juices)
Step-by-Step Instructions
Preparing the Roast
- Preheat your oven to 350°F (175°C).
- Prepare the crust paste: In a small bowl, mash together the garlic, horseradish, salt, and pepper. Stir in the olive oil to form a thick paste.
- Dry the roast: Pat the prime rib dry with paper towels. This helps the crust adhere and promotes browning.
- Coat the roast: Using your hands, massage the horseradish paste generously over the entire surface of the roast, coating it evenly.
- Arrange in the pan: Place the roast bone-side down in a large roasting pan. The ribs act as a natural rack, elevating the meat for even cooking.
Optional: Roasting Vegetables
- Scatter the carrots, parsnips, red onion, and halved garlic heads around the roast.
- Drizzle the vegetables with a bit of olive oil.
Roasting
- Roast the prime rib in the preheated oven for about 1.5 to 2 hours, or approximately 20 minutes per pound for medium-rare.
- Check the temperature: Insert an instant-read thermometer into the thickest part of the roast, not touching the bone. For medium-rare, aim for an internal temperature of 125°F (52°C). The temperature will rise another 5–10°F (3–5°C) as the roast rests.
- Rest the roast: Remove the prime rib from the oven and transfer to a carving board. Tent loosely with foil and let rest for at least 20 minutes. This allows the juices to redistribute, ensuring a moist result.
- Reserve the pan juices: Pour the juices from the roasting pan into a fat separator or bowl. After a few minutes, the fat will rise to the top. Discard the fat and reserve the flavorful juices for serving or for making the optional wild mushroom sauce.
Optional: Wild Mushroom Sauce
- Place a skillet over medium heat. Add a bit of olive oil and the butter.
- When the butter foams, add the mushrooms and thyme. Season with salt and pepper, and sauté until the mushrooms are golden and any liquid has evaporated.
- Deglaze with red wine, scraping up any browned bits. Cook until the wine is almost completely reduced.
- Add the reserved beef drippings or broth and let the liquid cook down.
- Remove from heat, stir in the cream and chives, and season to taste. Serve alongside the roast.
Carving and Serving
- Carve the roast: Using a sharp carving knife, cut along the rib bones to separate them from the meat. Slice the meat against the grain into thick, even pieces.
- Serve: Arrange slices on a platter, drizzle with reserved pan juices, and pass the mushroom sauce on the side.
- Garnish: Sprinkle with additional horseradish or fresh herbs if desired.
Tips for Perfect Prime Rib
- Let the roast come to room temperature before roasting for more even cooking.
- Use a meat thermometer to avoid overcooking. Prime rib is best served medium-rare.
- Don’t skip the resting period—this is crucial for juicy, tender meat.
- Customize the crust: Add minced fresh rosemary to the horseradish paste for another layer of flavor.
- Plan ahead: This recipe is ideal for holidays and celebrations, but it’s also simple enough for a weekend feast.
Nutritional Notes

Making Ahead and Storage
- You can prep the horseradish paste and coat the roast several hours before cooking. Keep it refrigerated.
- Refrigerate leftover prime rib in an airtight container for 3–4 days, or freeze for up to 2 months.
