How to Reheat Prime Rib
Leftover prime rib or standing rib roast.
The Short Answer
The best way to reheat prime rib is in the oven at low temperature. Low oven at 250 degrees F with beef broth in the pan and foil cover for 20-30 minutes preserves the original doneness.
Reheating Methods
🔥 Oven
Temperature: 250°F
Time: 20–30 minutes
Place slices in a baking dish with beef broth or au jus. Cover tightly with foil. Heat until 120-130 degrees F internal for medium-rare.
🍳 Stovetop
Time: 3–5 minutes
Heat au jus in a skillet until simmering. Add slices, spoon warm liquid over them. Gentlest method.
Do not reheat prime rib at high temperatures. That rosy medium-rare interior will be gone in minutes.
If you spent $80 on a prime rib, spend 25 minutes reheating it properly. The low-oven-with-broth method preserves the medium-rare interior.

The Bottom Line
The best way to reheat prime rib is in the oven at low temperature. The key to great reheated food is low-and-slow heat, moisture retention, and patience. Rushing with high heat dries food out and creates uneven hot and cold spots. When in doubt, go lower and slower.
