Ingredient notes

• Prime rib: Also known as a standing rib roast, a full roast usually has about seven ribs. This portion of the rib has a thick “cap” of heavily marbled meat that gives all the flavor and richness. Ask your local butcher for a small-end (or first-cut) rib roast or for the roast to be cut from the loin end. You can also ask the butcher to cut the bones off the ribs and tie them for you (Steps 1 and 2). Plan on one pound per person.

Step-by-step instructions

To cut the prime rib off the bone:

In this recipe, you “bone and tie” the roast which means: cut the meat off the bone first so you can salt it (for at least 24 hours) and brown it. Then you tie it back together and roast it. These extra steps ensure your prime rib is flavorful throughout.

1. Hold the meaty lobe in one hand and a sharp boning or chef’s knife in the other hand, run knife down length of first bone, following contours as closely as possible to separate it from meat.

2. Flip roast so uncut portion faces you. Holding bones back with your hand, cut meat from remaining ribs. Once meat is removed, proceed with seasoning and tying as directed in recipe.

To make the prime rib:

1. Using sharp knife, cut slits in surface layer of fat, spaced 1 inch apart, in crosshatch pattern, being careful not to cut into meat. Rub 2 tablespoons Kosher salt over entire roast and into slits. 

2. Place meat back on bones (to save space in refrigerator), transfer to large plate, and refrigerate, uncovered, at least 24 hours and up to 96 hours. 

3. Adjust oven rack to middle position and heat oven to 200 degrees. Heat oil in large skillet over high heat until just smoking. Sear sides and top of roast (reserving bone) until browned, 6 to 8 minutes total (do not sear side where roast was cut from bone).

4. Place meat back on ribs, so bones fit where they were cut, and let cool for 10 minutes. Tie meat to bones with 2 lengths of kitchen twine between ribs. 

5. Transfer roast, fat side up, to wire rack set in rimmed baking sheet and season with pepper. Roast until meat registers 110 degrees, 3 to 4 hours. Turn off oven, leave roast in oven, opening door as little as possible, until meat registers about 120 degrees (for rare) or about 125 degrees (for medium-rare) 30 minutes to 1 ¼ hours longer. 

6. Remove roast from oven (leave roast on baking sheet), tent loosely with aluminum foil, and let rest for at least 30 minutes or up to 1 ¼ hours. Adjust oven rack about 8 inches from broiler element and heat broiler. Remove foil from roast, form into 3-inch ball, and place under ribs to elevate fat cap. Broil until top of roast is well browned and crisp, 2 to 8 minutes.

7. Transfer roast to carving board. Slice meat into 3/4-inch thick slices. Season to taste with salt.

To make the mustard cream sauce:

1. In a small saucepan over medium heat, whisk together sour cream, heavy cream, yolks, mustard, vinegar, sugar, and ½ teaspoon salt. Cook, whisking constantly, until sauce thickens and coats the back of spoon, 4 to 5 minutes. 

2. Immediately transfer to serving bowl, stir in chives, and season with salt and pepper to taste. Serve warm or at room temperature. Makes about 3 cups.

Recipe tips and variations

• Yield: Plan for one pound of prime rib (uncooked) per person. This recipe uses a 6-pound, 3-bone rib roast and will feed 6 adults (or maybe 8 as part of a larger feast).
• Storage: Store leftovers covered in the refrigerator for up to 4 days.
• Make ahead: You can score the fat and season the meat up to 4 days in advance. Just store loosely covered in the refrigerator.
• Quality roast: The cost of Prime Rib can be on the high side, but splurging on this beautiful cut of meat is absolutely worth it.
• Leftovers: If you have any, pile thinly sliced leftover meat on Soft Yeast Buns with caramelized onions and mustard cream sauce or a dollop of horseradish. Or, add to an omelet or tuck into tortillas and serve with salsa.
• Prime rib doneness temperatures: The “final rested temperature” is the temperature after the roast is out of the oven and has rested for 15 to 20 minutes. Remove the roast from the oven when the internal temperature is 5-10 degrees below the final temperature to allow for carryover cooking (the temperature of the roast will continue to rise while it rests). The exact temperatures depend on the size and thickness of your roast.
