Prime Rib Roast

Prime rib roast is almost always our go-to for crowd-pleasing holiday dinners because it hits all the right notes. Picture this: carving into a beautifully roasted prime rib, its exterior crispy and bursting with flavors from garlic and butter, while the inside remains tender and juicy.

Unlike other slow-roasted prime rib recipes, we start by roasting at a high temperature of 450°F for the first 20 minutes to create a crust that locks in the juices. Then, we lower the oven temperature to 325°F and continue roasting for about an hour. This method ensures a crispy exterior and a tender, juicy interior while significantly reducing the cooking time.

It’s a showstopper that brings everyone to the table, eager to dig in. Pair with your favorite sides, like creamy mashed potatoes, roasted vegetables, or a fresh salad.

How Much Prime Rib to Prepare Per Person

In general, one rib feeds about two people. So, if you’re expecting 10 guests at your dinner party, you’ll aim for around 5 ribs.

When it comes down to buying, a general guide is about 6 to 8 ounces (170 to 227 grams) of cooked meat per adult. That means each rib should have at least 2 to 2.5 pounds (0.9 to 1.1 kilograms) of meat before cooking.

If your guests are big meat lovers or generally have hearty appetites, you might want to bump up the amount of prime rib per person.

Ingredients for Prime Rib Roast

Here are the ingredients you need for roasted prime rib in the oven:

How to Cook Prime Rib Roast

Bring to Room Temperature: Remove the prime rib from the refrigerator 2 to 3 hours before cooking to allow it to come to room temperature. This step is crucial for even cooking.

Preheat the Oven: Heat your oven to 450℉ (230℃). This high initial temperature will help sear the meat, creating a flavorful crust.

Prepare the Prime Rib: Pat the prime rib dry with paper towels. Removing moisture helps to achieve a better sear. In a small bowl, mix together softened butter, minced garlic, salt, chopped thyme, chopped rosemary, and black pepper to create an herb butter. Rub the herb butter mixture all over the exterior of the prime rib, covering all sides evenly.

Roast the Prime Rib: Place the prime rib on a roasting rack inside a roasting pan. Put it in the preheated oven and roast at 450℉ (230℃) for about 20 minutes. If the meat hasn’t seared well, give it a few more minutes.

Reduce Heat and Continue Roasting: After the initial sear, reduce the oven temperature to 325℉ (160℃). Continue roasting until the internal temperature of the meat reaches 125℉ (52℃) for rare; 135℉/57℃ for medium-rare; and 145℉/63℃ for medium.

Note: the Typhur Sync wireless meat thermometer is the best tool to monitor the internal temp of the meat. It boasts two 6-sensor probes which offer an accuracy of ±0.5°F, and its Bluetooth and wifi connectivity supports long-range monitoring up to 400 feet. It's very easy to use, simply insert the probe into the thickest part of the meat before placing the prime rib into the oven, making sure the safety line is completely immersed. Connect the device to your Phone, and select beef → roast → prime rib in the parameters list on the Typhur App. Set the target temperature to 125℉/52°C (rare). To begin the process, press the start button on your phone. You will receive the alerts when your ribs are done.

Rest the Meat: Once the desired internal temperature is reached, remove the prime rib from the oven. Let it rest for at least 15 minutes before slicing. Resting allows the juices to redistribute throughout the meat, ensuring it’s moist and flavorful when sliced.

Serve: Carve the prime rib into slices and serve with your favorite side dishes like mashed potatoes, roasted vegetables, or a fresh salad.

Don’t Forgot Rest your Prime Ribs

Why rest meat after cooking? After cooking, let your prime rib rest for at least 20 minutes. This allows the juices to redistribute throughout the meat, making it even more tender and flavorful.

The best thing about the Typhur Sync wireless meat thermometer is that it can identify the size of the meat piece, its state (fully defrosted, semi-defrosted, etc.), and the cooking environment. Therefore, the algorithm considers these variables and can predict when to remove the meat from heat and the necessary resting time.

Frequently Asked Question

How many hours does it take to cook a prime rib?

It typically takes about 15-20 minutes per pound to cook a prime rib at 325°F. For example, a 6-pound roast would take about 1.5 to 2 hours.

Is it better to cook prime rib at 325 or 350?

Cooking prime rib at 325°F is generally recommended for a more even and tender roast. Cooking at 350°F can cook it faster but may result in a slightly less tender roast.

What’s the difference between prime rib and rib roast?

Both come from the cow’s rib section, but a standing rib roast includes the entire rack of ribs, while prime rib refers to ribs cut from the loin area.

What is the secret of cooking a prime rib roast?

The secret to a perfect prime rib roast is low and slow cooking, using a reliable meat thermometer to monitor the internal temperature, and resting the meat before carving to retain its juices.

Is prime rib better cooked slow or fast?

Prime rib is better cooked slowly. Slow cooking at a lower temperature ensures even cooking and results in a tender, juicy roast.

How do restaurants make prime ribs so tender?

Restaurants often use a combination of low-temperature roasting and resting the meat to ensure tenderness. They may also use high-quality cuts of beef and age them for enhanced flavor and tenderness.

Do you cook prime rib covered or uncovered?

Cook prime rib uncovered to allow the exterior to develop a nice, flavorful crust. Covering the roast can result in steaming, which softens the crust.
