What Temp Should Prime Rib Be for Medium Rare?
Quick Scoop
Prime rib is one of those special-occasion cuts — rich, tender, and full of flavor. But if you’ve ever tried to get that just right blush-pink center, you know one degree can make the difference. So, what’s the perfect internal temperature for medium-rare prime rib?
🎯 The Golden Temperature
The ideal internal temperature for medium rare prime rib is 130°F to 135°F (54°C to 57°C) after resting. When you pull the roast from the oven:
- Remove it at 120°F to 125°F (49°C to 52°C).
- Let it rest for about 20–30 minutes — the temperature will rise to medium-rare perfection through carryover cooking.
Temperature Guide (for different doneness levels)
| Doneness | Internal Temp (Before Resting) | Final Temp (After Resting) | Appearance |
|---|---|---|---|
| Rare | 115–120°F | 120–125°F | Red center, very juicy |
| Medium Rare | 120–125°F | 130–135°F | Warm pink center |
| Medium | 130–135°F | 140–145°F | Pink throughout |
| Medium Well | 140–150°F | 150–155°F | Light pink center |
| Well Done | 155°F+ | 160°F+ | Brown, little pink |
🔍 Why Resting Matters
Resting isn’t just a chef’s superstition. When hot juices settle after cooking, the fibers relax and reabsorb moisture. Slice too early and you’ll lose that precious flavor. Pro tip: Tent the roast loosely with foil (don’t seal it) to keep it warm without trapping steam.

“Always trust your meat thermometer, not your oven.” – Chef forum user, 2025 holiday thread.
Professional chefs and home cooks alike recommend using a digital thermometer with an instant read. Oven temps can fluctuate, but your thermometer won’t lie. Some even go with reverse searing — slow roast at 250°F, then finish with a high-heat sear to lock in that crust.
