Step 3: Prepare the Pan

Place the roast on a rack inside a shallow roasting pan with the fat side facing up.

As the fat renders during cooking, it naturally bastes the meat, helping keep it moist.

Step 4: Roast

Preheat the oven to 550°F (288°C).

A traditional high-heat method often suggests roasting for a calculated number of minutes based on the roast’s weight, then turning the oven off and allowing the roast to rest inside the closed oven.

However, because oven temperatures and heat retention vary significantly, the safest approach is to monitor the roast with a meat thermometer and keep the oven door closed during the resting period.

Recommended Internal Temperatures

• Rare: 120–125°F (49–52°C)
• Medium-Rare: 130–135°F (54–57°C)
• Medium: 140–145°F (60–63°C)
• Medium-Well: 150–155°F (66–68°C)

The internal temperature will continue to rise slightly while the roast rests.

Step 5: Rest Before Slicing

Once the roast reaches your preferred doneness, let it rest before carving.

Resting allows the juices to redistribute throughout the meat, resulting in more tender, flavorful slices.

Slice against the grain and serve immediately.

Tips for the Best Prime Rib

For consistently excellent results:

Frequently Asked Questions

Can I use this method for other beef roasts?

Yes. Similar roasting techniques can work well with other large beef roasts, though cooking times and internal temperature targets may vary depending on the cut.

Should I cover the roast?

No. Roasting uncovered helps develop a beautifully browned crust.

Is bone-in or boneless better?

Both are excellent. Bone-in roasts often provide extra flavor and presentation, while boneless roasts are easier to carve.

Why should I use a meat thermometer?

A thermometer provides the most accurate way to determine doneness, since oven performance and roast sizes can vary.

How long should I let the roast rest?

Allow the roast to rest for at least 15–20 minutes before slicing so the juices redistribute throughout the meat.
