The Closed-Oven Method for Cooking a Prime Rib Roast (2024)

FAQs

What is the trick to cooking prime rib? ›

Keep the rib roast uncovered while you cook it to allow it to brown on the outside. You can also give it a little extra sear in a hot pan for a few minutes on each side after it's finished roasting.

A roast is a large cut of meat: it needs more seasoning than you might expect. Season it generously with kosher salt the day before roasting it and let it sit in the fridge uncovered overnight. When you take it out of the fridge before roasting, add pepper and any additional herbs.

How do restaurants make prime rib so tender? The secret to restaurant-style prime rib is cooking the meat super slow at low temperatures. I recommend cooking prime rib at no higher than 200 degrees F. This cooks the meat very slowly, turning the fat into butter and rendering the proteins juicy and soft.

Brown the roast at 500°F (or as high as your oven will go) for 15 minutes. Lower the oven to 325°F to finish roasting: Reduce the oven temperature to 325°F. Roast in the oven until the thermometer registers 115°F for rare or 120° for medium rare, and 130°F for medium.

The Benefits of Slow Roasting

First, slow roasting produces a Prime Rib that is tender, juicy, and has evenly cooked meat.

Placing the oven rack too high up will cause your roast to brown too quickly and burn! After 30 minutes in the oven, add a ½ cup of water to the bottom of the roasting pan. The key is to allow the onions to brown and caramelize while roasting, but not to burn and smoke in the fat.

Before you begin roasting, be sure your Prime Rib Roast is completely thawed. If frozen, thaw it in the refrigerator for at least 48 hours before preparing and bring the meat to room temperature. Remove your roast from the refrigerator for at least 1 hour (but no more than 2 hours) before roasting.

Place the roast fat side up, bone side down, in a large roasting pan. Cook for 15 minutes, then reduce the oven temperature to 325°F. This allows the heat to sear the roast, trapping the juicy flavors inside while the rest of the meat cooks. On average, each pound of rib needs 15 minutes to cook (i.e., a 4 lb.

We recommend a low, slow cook preceded by a good sear.

Should you salt a prime rib roast overnight? ›

For best results, salt your prime rib on all surfaces with kosher salt at least 45 minutes before you start cooking it, and preferably the day before, leaving it in the fridge uncovered overnight. Initially, the salt will draw out some moisture and end up dissolving in it.

Rub the Prime Rib with Oil and Garlic: Given the fattiness of this cut of meat, you can actually skip using the olive oil, but then you should also skip the fresh garlic. Make the Prime Rib Rub: In a small bowl combine salt, pepper, and Italian Seasoning and rub it into the roast.

Overcooking the Prime Rib

That's why prime rib is so expensive: it's a huge piece of extremely good beef. Therefore, it's important not to cook it beyond medium-rare. Going past that temperature means the roast will no longer be tender.

The rule of thumb for buying prime rib is to buy one pound per person. A bone-in standing rib roast will feed about 2 people per bone. Also, be sure to consider how many side dishes you plan to serve. If you are preparing a large holiday meal with plenty of other food you could plan on ½ – ¾ pound prime rib per person.

Leaving prime rib roast uncovered while roasting allows the meat to develop a nice brown crust. You should only cover the roast with aluminum foil if it is becoming too brown.
