I have a Prime loin roast vacuum sealed that I plan on opening and cooking in the coming days. My plan is to cook it as I would a prime rib — 230F oven to 125+F internal, let rest, so it comes to above 130F, stable, cool on the outside; crank oven to 550F, put roast back in for 6 more minutes once oven comes to temperature.
But... I’ve never actually seen instruction on this. Is cooking this the same way one would cook a prime rib a mistake? All online instructions suggest cooking at 350F or above. Thoughts welcome.
