One Of My Favorite Christmas Eve Dinner Dishes
Prime rib claims center stage during holiday season for a very good reason. It is said to be the king of beef cuts.
It’s called a standing rib roast because to cook it, you position the roast majestically on its rib bones in the roasting pan.
Beautifully marbled with fat, this roast is rich, juicy, and tender—a feast for the eyes and the belly.
It is one of the easiest to cook. You just start it in the oven at a high temperature to get good browning on the outside of the roast, and then cook it at a lower temperature to make sure the meat in the center doesn’t get over cooked.
There’s usually something for everyone with this roast. The ends are well done for those who can’t tolerate pink. The center should be a vibrant rare for those of us who must have our beef rare.
A full rack of prime beef is 7 ribs, which will easily serve 14 to 16 people (or more!). A full rack will not fit in my oven, so when I’m feeding a crowd, I cut the roast in half (3 ribs on one roast and 4 ribs on the other) and cook them in separate ovens.
As for estimating how big a roast you’ll need, the butchers I’ve talked to say to estimate 2 people for every rib. In my experience, that’s a LOT of meat! For the roasts we get, and given that we are serving a lot of food in addition to the roast, 3 people per rib is fine. If you want to error on the generous side, with plenty of leftovers, aim for 2 people per rib.
Note that just because you are ordering a “prime” rib, it doesn’t mean that you are getting USDA Prime. Most “prime ribs” we get from market are actually USDA Choice quality. If you want USDA Prime prime rib, which has more fat marbling throughout the meat, and which can easily cost 50% more per pound, you will likely need to special order it from your butcher.
Prime Rib Recipe
Yield: Estimate 2 people served per rib
Some older cookbooks will sometimes instruct you to remove excess fat from the roast. “Excess” fat is any fat more than an inch thick on the roast. Fat is what gives the roast flavor and to make it juicy and tender. Prime rib is expensive and you are paying good money for that fat so leave it on. Your butcher should have removed any excess fat.
The most important piece of advice I can give you regarding cooking a prime rib roast is to use a good meat thermometer! I recommend this ChefAlarm by ThermoWorks. With a remote thermometer you can tell exactly what the temperature of the meat is without having to open the oven door.
One standing rib roast, 3 to 7 ribs (estimate serving 2-3 people per rib), bones cut away from the roast and tied back to the roast with kitchen string (ask your butcher to prepare the roast this way)
Freshly ground black pepper
1 Remove the beef roast from the refrigerator 3 hours before you start to cook it. Sprinkle it with salt all over and let it sit, loosely wrapped in the butcher paper. Roasts should be brought close to room temperature before they go into the oven, to ensure more even cooking.
2 If your butcher hasn’t already done so, cut the bones away from the roast and tie them back on to the roast with kitchen string. This will make it much easier to carve the roast, while still allowing you to stand the roast on the rib bones while cooking.
3 Preheat your oven to 500°F (or the highest temp your oven reaches less than 500°F). Pat the roast dry with paper towels (pre-salting should have made the roast release some moisture), and sprinkle the roast all over with salt and pepper.
4 Place the roast fat side up and rib bones down in a roasting pan. Insert a meat thermometer into the thickest part of the roast, making sure that the thermometer isn’t touching a bone.
5 After browning the roast at a 500°F temperature in the oven for 15 minutes, reduce the oven temperature to 325°F. To figure out the total cooking time, allow about 11-12 minutes per pound for rare and 13-15 minutes per pound for medium rare. The actual cooking time will depend on the shape of the roast, how chilled your roast still is when it goes into the oven, and your particular oven. A flatter roast will cook more quickly than a thicker one. There are so many variables involved that affect cooking time, this is why you should use a meat thermometer. A prime rib roast is too expensive to “wing it”. Error on the rare side, you can always put the roast back in the oven to cook it more if it is too rare for your taste.
Roast in oven until thermometer registers 115°F for rare or 120°-130°F for medium. (The internal temperature of the roast will continue to rise after you take the roast out of the oven.)
Check the temperature of the roast using a meat thermometer an hour before you expect the roast to be done. For example, with a 10 pound roast, you would expect 2 hours of total cooking time for rare (15 minutes at 500° and 1 3/4 hours at 325°). In this case, check after 1 hour 15 minutes of total cooking time, or 1 hour after you lowered the oven temp to 325°. (A benefit of using a remote thermometer is that you don’t have to keep checking the roast, you’ll be able to see exactly what the temperature is by looking at the thermometer outside of the oven.)
If the roast is cooking too quickly at this point, lower the oven temperature to 200°F.
Once the roast has reached the temperature you want, remove it from the oven and place it on a carving board. Cover it with foil and let it rest for 30 minutes before carving. The internal temperature of the roast will continue to rise while the roast is resting.
6 Cut away the strings that were used to hold the roast to the rack of rib bones. Remove the bones (you can save them to make stock for soup if you want.)
Then, using a sharp carving knife, slice meat across the grain for serving, making the slices about 1/4-1/2 inch thick.
To make the gravy, remove the roast from the pan. Place pan on stove on medium high heat. Pour off all but 2 tablespoons of the drippings to a separate container.
Into the 2 tablespoons of drippings in the pan stir in 1 to 2 tablespoons of flour.
Stir with a wire whisk until the flour has thickened and the gravy is smooth.
Continue to cook slowly and stir constantly. Slowly add back the previously removed drippings (remove some of the fat beforehand if there is a lot of fat).
In addition add either water, milk, stock, cream or beer to the gravy, enough to make 1 cup. Season the gravy with salt and pepper and herbs.
Merry Christmas Everyone!!
