How to Cook Prime Rib
Learn how to cook prime rib with seasoning, roasting, thermometer checks, resting, carving, common mistakes, troubleshooting, and FAQs.
Quick Answer
To cook prime rib, season the roast, let it sit briefly at cool room temperature if food-safety conditions allow, roast with a hot start or steady moderate heat, use a thermometer to track doneness, rest well, then slice across the grain.
Ingredients and Tools
- Prime rib roast
- Salt and pepper
- Roasting pan
- Rack if available
- Food thermometer
- Knife
- Cutting board
Safety Precautions

Step-by-Step Instructions
- Step 1
Season ahead
Salt the roast and add pepper, garlic, or herbs.
- Step 2
Prepare the pan
Place the roast fat-side up on a rack or sturdy bed of vegetables.
- Step 3
Insert thermometer
Place the probe in the thickest center away from bone.
- Step 4
Roast
Use your chosen recipe temperature and monitor the internal temperature.
- Step 5
Remove before final target
Take the roast out a few degrees early because carryover heat continues cooking.

Rest
Rest the roast so juices settle and temperature evens out.
- Step 7
Carve
Slice across the grain and serve with pan juices or sauce.
Practical Example
Example: You season a rib roast, roast it while tracking temperature, pull it before the final target, rest it, and carve thin slices.
Common Mistakes
- Cooking by time only
- Skipping the thermometer
- Cutting without resting
