Expert tips

This recipe is written for a conventional oven. Do not use a toaster oven.

The temperature of the meat will continue to rise a little as it rests, so be sure to take it out a bit early so it doesn't overcook.

Letting the meat rest at room temperature from the fridge helps the meat cook more evenly.

With the pan drippings left in the pan, make a delicious simple gravy sauce.

If the prime rib is slightly under your preferred temperature, you can pan-fry the meat.
