✅ 4. Slow Roast Until Perfect
Reduce oven to 120°C / 250°F.
Cook until desired internal temperature (use meat thermometer):
Internal Temperature Guide
Rare: 48–50°C (118–122°F)
Medium-Rare (recommended): 54–57°C (130–135°F)
Medium: 60–63°C (140–145°F)
💡 A 6-lb roast usually takes 2–2.5 hours at low temperature.
✅ 5. Resting the Prime Rib
VERY IMPORTANT:
Remove roast from oven.
Tent loosely with foil.
Let rest 20–30 minutes.
Temperature will rise another 3–5°C while resting.
This makes the meat extremely juicy.
✅ 6. Slice & Serve
Remove bones if attached (they slide off easily).
Slice thick cuts (just like in the picture).
Serve with:
au jus
horseradish sauce
mashed potatoes
roasted vegetables
