This foolproof “mathematical method” takes the guesswork out of roasting prime rib, promising delicious results with minimal effort. Say goodbye to holiday meal stress and hello to prime rib perfection!
The Simple Math Behind Perfect Prime Rib
Chef John’s genius lies in a straightforward calculation that guarantees a perfectly cooked roast. Here’s the formula that will change your prime rib game forever:
Cooking Time Calculation: Multiply the exact weight of your prime rib (in pounds or kilograms, ensuring consistent units) by 5 minutes.
For example, if you have a 5.5-pound prime rib, the calculation would be 5.5 x 5 = 27.5 minutes. Round this number up to the nearest whole minute, which in this case is 28 minutes. This calculated time is the key to unlocking prime rib perfection.
The Foolproof Cooking Process:
- Room Temperature Roast: Critically, your prime rib must be at room temperature before cooking. This is non-negotiable for the mathematical method to work effectively, ensuring even cooking.
- High Heat Sear: Preheat your oven to a scorching 500 degrees Fahrenheit (260 degrees Celsius). Once preheated, place your room-temperature prime rib in the oven and cook for the exact calculated time (e.g., 28 minutes for a 5.5-pound roast).
- Oven Off Rest: After the initial high-heat cooking time, immediately turn off your oven completely. Crucially, do not open the oven door. Let the prime rib rest in the cooling oven for a full 2 hours. This resting period is essential for the carry-over cooking and moisture retention, resulting in incredibly tender and juicy meat.
- Serve and Enjoy: After the 2-hour rest, remove your prime rib from the oven, slice, and prepare to be amazed. You’ll be greeted with a perfectly pink, medium-rare center that’s sure to impress your guests.

Chef John’s Pro Tips for Prime Rib Success
While the mathematical method is incredibly simple, Chef John shares a few extra tips to guarantee prime rib victory:
- Oven Reliability: This method is designed for modern ovens with accurate digital temperature settings that indicate when preheated. Older ovens with manual controls might have temperature variations, potentially affecting results.
- Internal Temperature Monitoring: For extra assurance, especially with expensive prime rib, use a probe thermometer. Insert it into the thickest part of the roast and set an alarm for 125°F (for medium-rare). If the alarm goes off before the timer, remove the prime rib to prevent overcooking.
Elevate Your Prime Rib with Classic Pairings
