How To Cook A Small Prime Rib Roast

Prime rib roast is a classic and flavorful cut of beef that is perfect for special occasions or a Sunday family dinner. While cooking a large prime rib roast can be intimidating, cooking a small prime rib roast is much more manageable and takes less time. In this article, we will walk you through the step-by-step process of cooking a small prime rib roast, ensuring that it turns out tender, juicy, and delicious.

Step 1: Choose the right cut of meat
Start by purchasing a small prime rib roast from a reputable butcher or grocery store. Look for a bone-in roast, as the bone helps to distribute the heat evenly and adds flavor to the meat. Aim for a roast that weighs around 4 to 6 pounds, which will serve approximately 4 to 6 people.

Step 2: Prepare the meat
Remove the roast from the refrigerator and let it sit at room temperature for about an hour. This will allow the meat to cook more evenly. Meanwhile, preheat your oven to 450 degrees Fahrenheit (230 degrees Celsius).

Step 3: Season the roast
Season the roast generously with salt, pepper, and any other desired seasonings. Many people prefer to use a simple blend of salt, pepper, garlic powder, and rosemary. Ensure that the roast is evenly coated with the seasoning mixture.

Step 4: Cook the roast
Place the roast, bone-side down, in a roasting pan or a deep baking dish. Insert an oven-safe meat thermometer into the thickest part of the roast, making sure it doesn’t touch the bone. This will help you monitor the internal temperature of the roast.

Put the roast in the preheated oven and roast it at 450 degrees Fahrenheit (230 degrees Celsius) for about 15 minutes to sear the outside. Then, reduce the oven temperature to 325 degrees Fahrenheit (165 degrees Celsius) and continue roasting until the internal temperature reaches your desired level of doneness. Here is a guide for internal temperatures:

– Rare: 120-125 degrees Fahrenheit (49-52 degrees Celsius)
– Medium-rare: 130-135 degrees Fahrenheit (54-57 degrees Celsius)
– Medium: 140-145 degrees Fahrenheit (60-63 degrees Celsius)

It’s important to note that the cooking time will vary depending on the size of your roast and your desired doneness. As a general rule of thumb, estimate about 15-20 minutes per pound of roast. However, always rely on the internal temperature rather than the cooking time to determine when your roast is done.

Step 5: Rest and carve the roast
Once the roast reaches your desired internal temperature, remove it from the oven and let it rest for at least 15 minutes. This allows the juices to redistribute throughout the meat, resulting in a juicier roast. While resting, the internal temperature will continue to rise by about 5 degrees Fahrenheit (2-3 degrees Celsius). This is known as carryover cooking.

After the resting period, it’s time to carve the roast. Use a sharp carving knife to cut thin slices against the grain of the meat. Serve the prime rib roast with your favorite side dishes, such as roasted potatoes, steamed vegetables, or Yorkshire pudding.


Q: How do I know if my small prime rib roast is cooked to perfection?
A: The best way to determine the doneness of your small prime rib roast is by using a meat thermometer. Insert it into the thickest part of the roast, making sure it doesn’t touch the bone. Refer to the internal temperature guide mentioned above for your preferred level of doneness.

Q: Can I cook a small prime rib roast without a bone?
A: While cooking a bone-in roast is preferred to enhance flavor and even cooking, you can still cook a boneless small prime rib roast. Follow the same steps mentioned above, adjusting the cooking time slightly as boneless roasts tend to cook faster.

Q: What should I serve with a small prime rib roast?
A: Small prime rib roast pairs well with a variety of side dishes, including roasted potatoes, creamy horseradish sauce, Yorkshire pudding, roasted vegetables, or a fresh green salad. Choose your favorite sides to complement the rich and savory flavors of the roast.

Q: Can I use the drippings to make gravy?
A: Absolutely! The pan drippings from the small prime rib roast make an excellent base for a flavorful gravy. Skim off the excess fat, then add flour to make a roux and gradually whisk in beef broth until you achieve the desired consistency. Season with salt, pepper, and any additional herbs or spices you like.

Cooking a small prime rib roast doesn’t have to be complicated or intimidating. With the right preparation and following the steps outlined above, you can achieve a delicious and perfectly cooked roast that will impress your guests or satisfy your family’s cravings. Enjoy!
