Ingredients:
- 1 (3-bone) Standing Rib Roast, approximately 7–8 lbs
- 3 tbsp Kosher Salt
- 2 tbsp Coarsely Ground Black Pepper
- 1 cup Unsalted Butter, softened
- 6 cloves Garlic, minced
- 2 tbsp Fresh Rosemary, finely chopped
- 2 tbsp Fresh Thyme, finely chopped
- 1 tbsp Prepared Horseradish
Instructions:
- Pat the roast dry with paper towels. Rub the entire surface with kosher salt and black pepper. Place on a rack over a tray and refrigerate uncovered for 12–24 hours for a dry brine.
- Remove the roast from the refrigerator 2 hours before cooking to temper the meat, ensuring even cooking.
- In a small mixing bowl, combine softened butter, minced garlic, rosemary, thyme, and horseradish. Slather the compound butter over the top and sides of the roast.
- Preheat your oven to 250°F (120°C). Place the roast bone-side down on a wire rack in a heavy-duty roasting pan.
- Insert a digital probe thermometer into the thickest part of the meat. Roast until the internal temperature reaches 120°F (49°C) for medium-rare.
- Remove the roast from the oven and tent loosely with foil. Let it rest for 30–45 minutes; the temperature will rise to 130°F–135°F via carryover cooking.
- While the meat rests, preheat the oven to 500°F (260°C). Return the rested roast to the oven for 6–10 minutes until the exterior is deeply browned and sizzling.
- Carve the roast against the grain and serve immediately.
