Ingredients
Instructions
- 1. Remove the prime rib roast from the refrigerator 1 hour before cooking and allow it to come to room temperature — this ensures even cooking throughout.
- 2. Preheat oven to 450°F (230°C). Place a roasting rack inside a large heavy roasting pan.
- 3. In a small bowl, combine minced garlic, rosemary, thyme, kosher salt, cracked black pepper, smoked paprika, and olive oil to form a thick paste.
- 4. Pat the roast completely dry with paper towels, then rub the herb paste all over the entire surface, pressing firmly into every crevice and over the bones.
- 5. Place the roast bone-side down on the roasting rack. Roast at 450°F for 20 minutes to develop a deep mahogany crust.
- 6. Reduce oven temperature to 325°F (163°C) and continue roasting until an instant-read thermometer inserted into the thickest part reads 120°F for rare, 125°F for medium-rare, or 130°F for medium — approximately 2 hrs 45 mins to 3 hrs 10 mins depending on size.
- 7. Transfer the roast to a carving board, tent loosely with foil, and rest for 25–30 minutes (the internal temperature will rise 5–10°F during resting).
- 8. While the roast rests, make the au jus: place the roasting pan over medium heat on the stovetop, add beef stock and Worcestershire sauce, scraping up all browned bits. Simmer 5 minutes, strain through a fine-mesh sieve, and season with salt and pepper.
- 9. Make the horseradish cream: stir together sour cream, horseradish, chives, lemon juice, salt, and pepper in a small bowl. Refrigerate until serving.
- 10. Carve the roast by slicing between the bones, then slicing each section into thick individual portions. Serve immediately with warm au jus and horseradish cream on the side.
Tips & Notes
- – Dry-brine for maximum crust: salt the roast uncovered on a rack in the refrigerator 24–48 hours ahead for an even more flavorful, drier exterior that crisps beautifully.
- – Use a reliable instant-read thermometer — it is the single most important tool for a perfect prime rib roast every time.
- – Always rest the roast a minimum of 25 minutes; cutting too early will cause all the juices to run out onto the board.
- – For a larger roast (4–5 bones), add approximately 30–45 additional minutes of cook time at 325°F and monitor with a thermometer.
- – Leftover prime rib slices make incredible sandwiches on toasted hoagie rolls with au jus for dipping the next day.

The reverse-sear method — roasting low and slow first, then blasting with high heat at the end — is the backbone of this recipe’s reliability. Traditional high-heat-first approaches can leave you with an overcooked gray band just beneath the crust, which is exactly what you want to avoid with a cut this special. Starting low lets the interior come up to temperature gradually and evenly, so when you hit it with that final burst of heat, the crust forms quickly without pushing the center past your target doneness. Pair that with a salt-and-herb rub applied the night before, and the seasoning has time to work its way into the meat rather than just sitting on the surface. The result is a roast that is seasoned through and through, with a crust that is genuinely crisp and a center that stays a consistent, beautiful pink from edge to edge.
What You’ll Need: Ingredients and Notes
The ingredient list for a prime rib roast is refreshingly short, which means the quality of each component matters. Start with a bone-in standing rib roast, somewhere between three and seven ribs depending on your crowd. A three-rib roast feeds about six to eight people comfortably. Ask your butcher to trim the cap fat to about a quarter inch — you want enough fat to baste the meat as it cooks, but not so much that it pools in the pan and smokes aggressively.
- Kosher salt — use about half a teaspoon per pound of meat; it draws out moisture initially and then gets reabsorbed, seasoning deep into the flesh
- Freshly ground black pepper — coarse grind gives you better crust texture than fine
- Fresh rosemary — strip the leaves and chop them; dried rosemary works in a pinch but fresh is noticeably brighter
- Fresh thyme — same principle as rosemary; use generously
- Garlic — minced or pressed into a paste; you want it to cling to the fat, not slide off
- Neutral oil or softened beef tallow — helps the herb paste adhere and promotes browning
- Beef broth — for the bottom of the roasting pan; it keeps drippings from scorching and gives you the start of a pan sauce
You do not need a special roasting rack if you do not own one. Setting the roast bone-side down directly in a heavy roasting pan works perfectly — the bones act as their own natural rack and elevate the meat above the drippings.
How to Make Prime Rib Roast: A Full Walkthrough
The night before you plan to cook, pat the roast completely dry with paper towels. Combine your salt, pepper, chopped rosemary, thyme, minced garlic, and oil into a thick paste and rub it all over the roast, getting into every crevice around the bones and over the fat cap. Place the roast uncovered on a rack set over a rimmed sheet pan and refrigerate it overnight. This dry-brining step is not optional if you want the best possible result — the uncovered rest in the refrigerator also dries out the surface, which helps you get a better crust later.
On the day of cooking, pull the roast from the refrigerator at least one hour before it goes into the oven. You want to take the chill off so the meat cooks more evenly. Preheat your oven to 250 degrees Fahrenheit. Pour about a cup of beef broth into the bottom of your roasting pan, set the roast bone-side down, and slide it onto the center rack.
Roast low and slow until an instant-read thermometer inserted into the thickest part of the meat — away from the bone — reads about 10 to 15 degrees below your target. For medium-rare, that target is 130 to 135 degrees Fahrenheit, so you are pulling the roast at around 118 to 120 degrees. A three-rib roast at 250 degrees typically takes two to two and a half hours, but your thermometer is more reliable than any clock.
Once the roast hits that pull temperature, remove it from the oven and tent it loosely with foil. Crank the oven to 500 degrees Fahrenheit and let it fully preheat — this takes about 20 minutes. Slide the roast back in, uncovered, and roast at 500 degrees for 8 to 10 minutes, watching closely, until the exterior is deeply browned and the fat cap has crisped. Remove the roast and let it rest, loosely tented, for at least 20 minutes before carving. The internal temperature will continue to rise during this rest, landing right in that ideal window.
To carve, stand the roast upright and slice along the curve of the bones to remove them as a rack. Then lay the roast flat and slice across the grain into portions as thick or thin as you prefer.
Tips for the Best Result Possible
- Do not skip the overnight dry brine. Even four hours is better than nothing, but overnight transforms the depth of flavor and surface texture.
- Use a reliable leave-in probe thermometer if you have one, so you can monitor the temperature without opening the oven repeatedly.
- The high-heat sear at the end goes fast — stay nearby and check every few minutes to avoid over-browning.
- Resting time is non-negotiable. Cutting into the roast too early sends all the juices running across the cutting board instead of staying in the meat.
- Save every drop of the drippings in the pan. They become an extraordinary base for a simple jus or a rich gravy with just a splash of beef broth and a little seasoning.
- If your oven runs hot or uneven, rotate the pan once during the low-temperature phase to promote even cooking.
Ways to Change It Up and Make It Your Own
Once you are comfortable with the method, there is plenty of room to make this roast suit your table perfectly.
- Horseradish herb crust — stir prepared horseradish into your herb paste for a sharp, peppery bite that cuts through the richness of the beef beautifully.
- Smoked paprika and cumin rub — swap the rosemary and thyme for smoked paprika, cumin, and a pinch of cayenne for a roast with a warmer, earthier character.
- Boneless rib roast — if you prefer easier carving, a boneless roast follows the same method; just reduce your cooking time slightly since the bones no longer act as insulators.
- Smaller holiday roast — a two-rib roast works well for four to five people and comes together faster, making it a practical option for a smaller holiday gathering.
- Mustard crust variation — spread a thin layer of whole-grain mustard over the fat cap before applying the herb rub for extra tang and a beautiful speckled crust.
- Garlic-studded roast — use a thin knife to cut small slits across the fat cap and insert slivers of raw garlic deep into the meat before applying the rub; the garlic softens and mellows as it cooks, perfuming the interior.
How to Store and Reheat Leftovers
Leftover prime rib stores well and reheats better than most cuts, provided you are gentle about it. Wrap individual slices tightly or store them in an airtight container with a spoonful of the pan drippings spooned over the top to keep them moist. Refrigerate for up to four days.
To reheat, place slices in a shallow baking dish with a splash of beef broth, cover tightly with foil, and warm in a 250-degree oven until just heated through — about 20 to 30 minutes depending on thickness. Avoid the microwave for reheating if you can; it tends to push the meat past medium-rare quickly and changes the texture. If you are short on time, a low skillet with a lid and a tablespoon of broth works reasonably well as a quicker alternative.
Leftover slices are also excellent cold, sliced thin and layered into a hearty sandwich on crusty bread with horseradish cream and thinly sliced onions. Nothing about a well-cooked prime rib goes to waste.
Frequently Asked Questions
How many ribs should you buy? Plan on one rib for every two to three guests, depending on how generous you want the portions and whether you are serving multiple side dishes. A four-rib roast is a comfortable choice for eight people with sides.
Can you season the roast just a few hours before cooking? Yes, though overnight is ideal. Even a two-hour salted rest at room temperature before cooking is better than seasoning immediately before it goes into the oven.
What internal temperature means medium? Medium doneness sits at around 140 to 145 degrees Fahrenheit. Pull the roast at about 130 degrees if medium is your goal, then account for the carry-over rise during the high-heat sear and rest period.
Do you need to use bones-in specifically? Bone-in is strongly recommended for flavor and moisture, but a boneless roast works if that is what is available. Just adjust your cooking time and keep your thermometer handy.
