Prime Rib Perfection (Oven-Roasted)
Serves: 6–8
Prep time: 15 minutes (+ resting)
Cook time: ~2–3 hours (depending on size)
Ingredients
Prime rib roast (bone-in or boneless): 4–5 lb (1.8–2.3 kg)
Olive oil: 2 tbsp
Unsalted butter: 4 tbsp, softened
Garlic: 6 cloves, minced
Fresh rosemary: 2 tbsp, finely chopped
Fresh thyme: 2 tbsp, finely chopped
Salt (kosher or sea salt): 2½ tsp
Black pepper: 2 tsp
Smoked paprika or garlic powder (optional): 1 tsp
Instructions
- Bring to room temperature
Remove the prime rib from the fridge 1–2 hours before cooking.
Pat dry with paper towels (this helps the crust form). - Season generously
Mix butter, olive oil, garlic, rosemary, thyme, salt, pepper, and paprika.
Rub the mixture all over the roast, including the ends. - Preheat oven
Preheat oven to 230°C / 450°F.
Place roast fat-side up on a rack in a roasting pan. - Sear for crust
Roast at 450°F (230°C) for 20 minutes to develop a deep, flavorful crust. - Slow roast
Reduce oven temperature to 165°C / 325°F.
Continue roasting until internal temperature reaches:
120–125°F (49–52°C) → Rare
130–135°F (54–57°C) → Medium-rare (recommended)
140°F (60°C) → Medium
⏱️ Approx. 15 minutes per pound, but always rely on a thermometer. - Rest (critical!)
Remove roast from oven and loosely tent with foil.
Rest 20–30 minutes.
(Temperature will rise 5–10 degrees, and juices will redistribute.)
🔪 To Serve
Slice against the grain into thick or thin cuts.
Serve hot with pan juices or au jus.
Optional Quick Au Jus
Place roasting pan over medium heat.
Add 1½ cups beef broth.
Scrape browned bits from the pan.
Simmer 5 minutes, strain, and serve.
