Ingredients

Scale

1 (4 to 5 pound) prime rib roast
1/3 cup olive oil
2 Tablespoons lemon juice
4 garlic cloves, minced
3 Tablespoons rosemary leaves
1 teaspoon pepper


Instructions

1. Place the roast in a shallow roasting pan and set aside 30 minutes to room temperature. Preheat oven to 450 degrees F.

2. Combine all other ingredients. Rub the prime rib with mixture. Bake 15 minutes until the meat begins to brown.

3. Reduce heat to 325 degrees F and continue cooking according to the chart below:

Cooking Time for Rare (120°)

3 Ribs, 7 to 8 lbs. 15 minutes at 450°, Then 1 ¼ to 1 ½ hours at 325°
4 Ribs, 9 to 10 lbs. 15 minutes at 450°, Then 1 ½ to 2 hours at 325°
5 Ribs, 11 to 13 lbs. 15 minutes at 450°, Then 2 to 2 ½ hours at 325°
6 Ribs, 14 to 16 lbs. 15 minutes at 450° Then, 2 ¾ to 3 hours at 325°
7 Ribs, 16 to 18 lbs. 15 minutes at 450° Then, 3 to 3 ¾ hours at 325°

4. Every half hour or so, baste the ends of the roast with the drippings. Use the meat thermometer about 30 minutes before the end of the roasting time. Make sure to insert it in the thickest part of the meat, not touching the fat or bone.

When the internal temperature reaches 120°, remove roast from the oven and cover with foil. If you remove a prime rib from the oven when the temperature is over 125°, it will be way too dry and overdone.

5. Let the roast sit for twenty to thirty minutes. It will continue to cook during this time, reaching a temperature of about 125° to 130°. This resting period allows the juices and flavors to permeate the roast.
