Trying this new prime rib cooking method today for Christmas

[Duncanpup]

Has anyone ever tried this if so any advice would be appreciated thank you in advance.
Liz would sear prime rib and then into oven low and slow.
Yet I’m gonna try this.
Take roast out let it sit for 2 hours preheat oven to 500 degrees.
Im gonna cover the prime rib in Liz’s butter and garlic rub no searing then pop it into the oven 5 minutes a pound now this is 3 pound rib so after 15 minutes turn oven off.

And let it continue to cook for 2 hours don’t open the oven at anytime.
Then remove it temp should be around 130 degrees let it sit for 15 minutes then serve.

Those who like their meat cooked a little more the edge slices should be for them.
Those of us who like rare the center should be nice and pink.
