Notes on Prime Rib Roast

Found this in Fine Cooking...

We’ve all been there. You’re cooking a big, expensive roast for a large family gathering when the doubts begin to set in: Is it done yet? It is undercooked? (Or worse: Is it overcooked?) Well, I’m here to take that worry away with a simple method: Reverse Searing.

When you cook a roast, you typically brown the outside first to develop a deeply flavored crust before finishing it in the oven. Reverse searing is the opposite. You cook the roast slowly in a low oven until it’s just about done, and only then do you sear it in a scalding hot pan or blazing oven. Not only does the reverse sear work, but it works beautifully, keeping the inside of the roast cooked to the same rosy color from the center to the very edge, where a savory, deeply browned crust meets it.

Here’s why it works: Large cuts of meat, such as standing rib roast or even beef tenderloin, cook more evenly at lower temperatures. As the roast nears doneness, the lower heat prevents the meat’s internal temperature from spiking to overdone, which can happen in a blink when roasting with high heat. As an added benefit, searing already-cooked meat takes less time than searing raw meat, and less time searing helps keep that sad gray outer ring of overcooked meat at bay.

With this genius method, you can cook the meat hours ahead of the final sear, allowing you to pull the rest of the meal together without worrying about when the meat will be done.

Good to know…

Temperature Trumps Time

The times given for roasting in the following recipes are a guide and will vary depending on your oven, the size of the roast, and whether you use grain- or grass-fed beef. Use an instant-read thermometer and rely on temperature to gauge doneness.

Sitting Out Is Safe

The USDA, which errs on the conservative side, says it’s OK to leave an almost-cooked roast out at room temperature for up to 2 hours.

Two Ways To Sear

Searing on the stove allows for more control since you can see the browning, but the oven is hands off with less smoke and spattering. The choice is yours.

No Rest Required

If you roasted well ahead of the final sear, you don’t need to let the roast rest before slicing. Go ahead and carve away.


As the time gets closer to that Christmas meal, I need to do a little planning ahead.  I'll add anything I can think of that will help.
