Best Way to Cook Prime Rib
You need to know how to cook prime rib, and how to cook it well. This method of starting the oven at a high temperature and then lowering it means you get a beautifully caramelized crust on the outside of the meat, while the inside is still perfectly juicy and tender.
All About How to Make Prime Rib
A beautiful bone-in prime rib roast is the crown jewel of many holiday meals. Even though it generally costs a pretty penny, this lavish cut of meat is worth it when properly prepared.
Since it’s so expensive, you want to cook it right. When it’s beautifully browned on the outside and medium rare on the inside, you’ve done your job.
This post will walk you through our method of how to cook prime rib, so that it comes out perfectly every single time. This method uses a blast of super high heat for a short period of time to sear the outside of the meat, and then slow cooking it to a succulent, juicy finish.
Why you’ll love Prime Rib in Oven
- Once it goes into the oven, you don’t have much to do other than reduce the oven temperature once and monitor the internal temp of the meat. Your hands are free to prepare side dishes without constantly supervising the meat.
- The method of starting the oven at a high temperature and reducing it to a lower one means you get a beautifully caramelized crust on the outside of the meat, while the inside is still perfectly juicy and tender.
What is Prime Rib?
Also known as standing rib roast, prime rib is a cut of beef from the primal rib section of the cow. It’s prized for rich marbling (and thus, flavor) and tenderness. Typically, prime rib is roasted with the bone in to achieve the richest flavor.
How much Prime Rib Per Person?
When planning a feast, aim for about 1 pound of bone-in prime rib per person for a satisfying portion. It sounds like a lot, but it takes into account the weight of the bone, as well as the fatty marbling that often goes uneaten (but enhances the flavor of the meat).
What you’ll need for the Best Prime Rib Roast Recipe Ever
- bone-in rib roast – I like a 6 to 7 pound roast (3 bones) to feed 6 people comfortably and maybe have a bit of leftovers.
- rub – see my post about Prime Rib Rub for a rub that is a combination of fresh herbs, garlic and shallots. It forms an irresistible crust on the outside of the roast.
- oil – vegetable or canola oil is what you want for this prime rib recipe, because it can withstand the very high oven temperature we’ll be using. Olive oil will burn and become bitter.
How to Cook Prime Rib: The Prep
- ROOM TEMP. Take the meat out of the fridge 2 hours before cooking to bring it to room temperature. Do not skip this step, because this is crucial to get an even cook throughout.
- RUB. Preheat the oven. Pat the roast very dry with paper towel, then drizzle the roast with oil and rub it on all sides. Then, slather the roast all over with the rub.
How to Cook a Prime Rib
- ROAST. Place the roast bone side down in a shallow roasting pan, rimmed baking sheet, or shallow baking dish. Transfer to a 450 degree F oven until a deep sear develops on outside of meat, then reduce oven temperature to 300 degrees F and continue roasting until center of roast reaches your desired temperature (more on this below).
- REST. After cooking, allow the meat to rest for 20 to 30 minutes before carving and serving with horseradish cream sauce. You can tent the cooked roast loosely with foil while it rests, to keep it warm for serving if you need to extend the rest time beyond that.
How long to cook Prime Rib
For a 6 to 7 pound roast, I roast the meat at 450 degrees for 20 to 30 minutes to get a nice crust on the outside of the meat, then reduce the oven temperature to 300 degrees F and cook until the center of the roast reaches 125 F for medium rare once rested. This could be around an hour, or a bit longer.
Prime Rib Temperature Chart
Be sure to note that the roast temperature will rise up to another 5 degrees while resting, so you’ll want to pull it from the oven 5 degrees before your target doneness temperature, as outlined in the chart below.
| Desired Doneness | Pull From Heat At | Final Temperature |
| Rare | 115 degrees F | 120 to 129 degrees F |
| Medium Rare | 125 degrees F | 130 to 134 degrees F |
| Medium | 130 degrees F | 135 to 144 degrees F |
| Medium Well | 140 degrees F | 145 to 154 degrees F |
| Well Done | 150 degrees F | 155 to 164 degrees F |
Home Chef Tips for How to Cook a Prime Rib
- Give the meat a bit of a massage. Don’t just lightly coat the meat with the rub, really massage it in a little bit so the flavor penetrates the meat.
- Leave your roast uncovered while cooking so that the outside gets nice and brown.
- It’s critical that you use a good quality thermometer to achieve the proper cook on the roast in this prime rib recipe. An instant read probe thermometer comes in handy in the kitchen quite often, but there’s nothing like a probe meat thermometer with an external display for cooking a roast.
Best Sides for Prime Rib
There’s so many great options for side dishes to pair with prime rib for a special feast. Usually, I’ll choose one type of potato, one or two other vegetables, and then bread or rolls.
