Ingredients
Scale
1 (5-7 pound) standing rib roast (bone-in ribeye)
3 tablespoons olive oil
2 tablespoons kosher salt
1 tablespoon black pepper
1 tablespoon dried rosemary
1 tablespoon dried thyme
4 cloves garlic, minced
1 teaspoon onion powder
Instructions
Remove the prime rib from the refrigerator at least 2 hours before cooking to bring it to room temperature. Preheat your oven to 450°F (230°C).
In a small bowl, combine olive oil, salt, pepper, rosemary, thyme, minced garlic, and onion powder. Mix well to form a paste.
Pat the prime rib dry with paper towels. Rub the herb and garlic paste all over the roast, ensuring it’s evenly coated.
Place the roast, bone-side down, on a rack in a roasting pan.
Roast at 450°F (230°C) for 15 minutes.
Reduce the oven temperature to 325°F (160°C) and continue roasting. For medium-rare, aim for an internal temperature of 120-125°F (49-52°C) for a 5-7 pound roast, which typically takes about 15-20 minutes per pound. Use a meat thermometer inserted into the thickest part of the roast, avoiding the bone.
Once the desired temperature is reached, remove the roast from the oven. Tent it loosely with foil and let it rest for 20-30 minutes before carving. This resting period is crucial for juicy, tender meat.
Carve the prime rib into thick slices against the grain. Serve immediately.
Notes
For a flavorful jus, deglaze the roasting pan with beef broth after removing the roast, scraping up any browned bits. Simmer briefly and strain.
Horseradish cream sauce is a classic accompaniment. Mix prepared horseradish with sour cream or whipped cream, a pinch of salt, and a dash of Worcestershire sauce.
Consider using a sous-vide precision cooker for ultimate temperature control before searing for an exceptionally even cook.
