Instructions

Preheat the oven to 450°F (230°C) and place a rack in a roasting pan.
In a small bowl, combine Dijon mustard, prepared horseradish, minced garlic, rosemary, thyme, salt, black pepper, and olive oil. Stir until smooth.
Pat the prime rib dry and rub the horseradish mixture evenly over the meat. Let it sit at room temperature for 30–45 minutes.
Place the roast bone-side down on the rack and roast for 15 minutes to create a crust.
Reduce the oven temperature to 325°F (165°C) and continue roasting until the internal temperature reaches desired doneness: Rare 120–125°F, Medium-rare 130–135°F, Medium 140–145°F.
Remove roast from oven, tent loosely with foil, and rest for at least 20 minutes.
Preheat oven to 400°F (200°C) if needed for Brussels sprouts.
Toss halved Brussels sprouts with olive oil, salt, pepper, and garlic powder. Spread on a baking sheet and roast for 20–25 minutes, stirring halfway through, until golden and crisp. Optionally, sprinkle with Parmesan before serving.
Slice the rested prime rib against the grain and serve with roasted Brussels sprouts.

Notes

Allow meat to rest after roasting to retain juices.
Adjust roasting times depending on the size of the prime rib.
Brussels sprouts can be roasted alongside the prime rib if oven space allows.
Brush pan drippings over sliced meat for extra flavor.
