Garlic Herb Prime Rib Recipe for a Tender Holiday Roast

Prime rib, also called a standing rib roast, is a classic celebratory roast in the United States; this version coats beef with garlic, parsley, rosemary, thyme, and butter. Family and regional versions vary, but a well-browned crust, careful thermometer checks, and a generous rest make this roast especially satisfying with its own pan juices.

Ingredients

1 bone-in beef rib roast, about 6 lb (2.7 kg), with 3 ribs, preferably tied by the butcher
2 tbsp (18 g) kosher salt
2 tsp (5 g) freshly ground black pepper
1/2 cup (113 g) unsalted butter, softened
8 garlic cloves (about 25 g), finely grated or minced
2 tbsp (6 g) finely chopped fresh rosemary
1 tbsp (3 g) fresh thyme leaves, chopped
2 tbsp (8 g) finely chopped fresh flat-leaf parsley
1 tbsp (15 g) Dijon mustard
1 tbsp (15 ml) olive oil
1 cup (240 ml) low-sodium beef stock, for the pan juices

Instructions

Heat the oven and prepare the roast. Set a rack in the lower third of the oven and preheat to 450°F (232°C). Remove any loose pieces of bone or excess surface fat, but leave a thin fat cap to help baste the meat. If the roast is not already tied, tie it snugly between the bones with kitchen twine so it holds a compact shape. Pat the surface dry with paper towels. Place it bone-side down, fat-side up, in a sturdy roasting pan fitted with a rack, if available.
Season and make the herb butter. Sprinkle the salt and pepper evenly over all sides of the roast, including the ends. In a small bowl, mix the softened butter with the garlic, rosemary, thyme, parsley, Dijon mustard, and olive oil until combined. Spread the mixture across the top and sides of the roast. A little mixture may slide off; use your hands to press it back onto the meat. Keep the stock aside for making the pan juices.
Start with high heat. Roast at 450°F (232°C) for 20 minutes to brown the outside. Do not cover the pan or add stock yet, since moisture at this stage can slow browning. The herbs and garlic will darken, but the butter coating should not be smoking heavily; if the pan is smoking, check that the oven is at the correct temperature and that the roast is not touching a heating element.
Lower the temperature and roast to temperature. Without opening the oven for long, reduce it to 325°F (163°C). Continue roasting for about 1 hour 45 minutes to 2 hours, checking the center after about 1 hour 30 minutes at the lower temperature. Cooking time is an estimate and changes with the roast’s shape, starting temperature, and oven. Insert an instant-read or leave-in thermometer into the thickest part, avoiding bone and large pockets of fat. USDA FSIS gives 145°F (63°C), followed by at least a 3-minute rest, as the safe minimum internal temperature for whole cuts of beef; use a food thermometer to verify it. If the roast has not reached 145°F (63°C), return it to the oven and check again every 10 to 15 minutes.
Rest the roast. Transfer the roast to a carving board and loosely tent it with foil. Rest for 30 minutes before carving. This is longer than the USDA FSIS minimum rest and gives the juices time to settle while you finish the pan juices. Do not wrap it tightly, which can soften the browned crust.
Make simple pan juices. While the roast rests, carefully pour off excess fat from the pan, leaving the browned bits behind. Set the pan over a burner on medium heat if it is stovetop-safe, or scrape the drippings into a small saucepan. Add the beef stock and scrape up the browned bits as it simmers for 3 to 5 minutes. Taste before adding salt, since the drippings may already be well seasoned. Strain if you prefer a smooth jus, then serve warm.
Carve and serve. Snip and remove the twine. If the bones are still attached, run a long carving knife along their curve to separate them from the roast; slice the meat across the grain into portions about 1/2 inch (1.3 cm) thick. Arrange the slices on a warm platter and pass the pan juices alongside.

Tips

Let the thermometer decide. The cooking time is a useful estimate, not a guarantee. A narrow roast may finish sooner than a thick one of the same weight, and ovens can differ. Check the center without touching bone, and avoid cutting into the roast to judge doneness because that releases juices.
Keep the roast dry before seasoning. Patting the surface dry helps the outside brown. If you have time, you can salt the roast uncovered on a rack in the refrigerator for 8 to 24 hours, then continue with the recipe. That optional dry-brine adds waiting time, so it is not included in the recipe-facts total; the surface may brown especially well, and the seasoning will taste more evenly distributed.
Use dried herbs only if needed. Fresh rosemary and thyme give the butter a lively, aromatic flavor. If using dried herbs, substitute 2 tsp (about 2 g) dried rosemary and 1 tsp (about 1 g) dried thyme for the fresh amounts; crush them between your fingers first. The result tastes a little earthier and less fresh. Fresh parsley is best added to the butter as written, but it can be omitted.
Watch the garlic and salt. Finely grated garlic sticks to the butter and seasons the crust evenly; large pieces can scorch during the hot start. Kosher salt varies by brand and crystal size, so weigh it when possible. If using fine table salt instead, use about 1 tbsp (18 g) rather than 2 tablespoons, or the roast may taste too salty.

Serving Suggestions

Serve the roast as the centerpiece of a holiday meal or a special Sunday dinner. Creamy mashed potatoes, roasted potatoes, Yorkshire pudding, or a crusty loaf all work well for catching the pan juices. For vegetables, pair the rich beef with simply roasted carrots, green beans, Brussels sprouts, or a crisp salad dressed with a sharp vinaigrette. Horseradish sauce is a traditional-feeling accompaniment: its clean, peppery heat cuts through the butter and beef without needing to change the roast itself.

For a relaxed meal, place sliced beef on a warm platter and keep the jus in a small pitcher so guests can add as much as they like. If serving a group with different preferences, carve a few slices from the ends and center separately; the ends are generally more cooked than the middle. Serve promptly after carving, since thin slices cool and dry more quickly than the whole roast.

Variations

Use a boneless rib roast. A boneless roast works with the same seasoning. Ask the butcher to tie it, or tie it at 1 1/2-inch (4 cm) intervals so it cooks evenly. Bone-in and boneless roasts do not always cook at identical rates, so rely on the thermometer rather than assuming the listed time will be exact.

Change the herb mix. Swap the rosemary for an equal amount of chopped sage, or use half rosemary and half sage. A small amount of chopped chives can replace some of the parsley. Keep the total amount of fresh herbs close to the recipe quantity so they season the butter without overwhelming the meat.

Make a pepper-forward crust. Add 1 tsp (2 g) crushed peppercorns to the herb butter for a more assertive bite. For a milder flavor, use only 1 tsp (2.5 g) ground black pepper in the seasoning and leave out the extra peppercorns. Avoid adding wet ingredients such as lemon juice to the butter, since a loose coating is more likely to run off during roasting.

Serve with a thicker sauce. For a more substantial gravy, after making the pan juices whisk 1 tbsp (8 g) flour into 1 tbsp (14 g) melted butter in a saucepan, cook for about a minute, then gradually whisk in the stock and drippings. Simmer until lightly thickened. This creates a gravy rather than a clear jus, so expect a softer, less concentrated beef flavor.

Storage and Reheating

Refrigerate leftover beef and pan juices within 2 hours of cooking. Store them in separate airtight containers, or keep the meat in a shallow container so it chills promptly. Cooked prime rib keeps for 3 to 4 days in the refrigerator. For longer storage, freeze sliced portions with a little jus in a freezer-safe container for up to 2 to 3 months for best quality; thaw overnight in the refrigerator.

To reheat, place slices in a covered oven-safe dish with a spoonful or two of stock or pan juices. Warm in a 300°F (149°C) oven until the leftovers reach 165°F (74°C), checking with a food thermometer. Reheating time varies with slice thickness and quantity, but thin slices may take about 10 to 15 minutes. A microwave also works: cover the meat, heat in short intervals, and check the temperature. Avoid prolonged high heat, which can make the beef tough. Reheat only the portion you plan to eat.

Frequently Asked Questions

Is prime rib the same as a standing rib roast?
In common U.S. usage, prime rib refers to a beef roast cut from the rib section, and a bone-in version is often called a standing rib roast because it can stand on its rib bones in the pan. The word “prime” in the dish’s name does not guarantee a particular USDA grade; check the package or ask the butcher about the grade and cut.

Can I cook this roast to medium-rare?
Many classic prime rib recipes aim for a rosy center, but USDA FSIS lists 145°F (63°C) with a minimum 3-minute rest as the safe minimum for whole cuts of beef. This recipe uses that safety guidance. If you choose a lower temperature, understand that it is below the USDA safe minimum; use a reliable thermometer and make an informed choice rather than relying on color alone.

Should I cover prime rib while it roasts?
No. Roast it uncovered so the surface can brown and the herb butter can form a crust. After cooking, loosely tent it with foil while it rests. A tight foil covering traps steam and softens the crust, so leave room for air to circulate.

Can I prepare the herb butter ahead?
Yes. Mix the butter, garlic, herbs, mustard, and oil up to 2 days ahead and keep it covered in the refrigerator. Let it soften enough to spread before using. You can also season the roast and refrigerate it uncovered for 8 to 24 hours, but keep raw beef refrigerated and add that chilling period to your schedule.

What if I do not have a roasting rack?
You can set the roast bone-side down directly in a sturdy roasting pan; the bones provide some lift. Alternatively, arrange thick-cut onion halves or sturdy carrot pieces beneath it to raise it slightly. They may brown in the drippings and add flavor, but they are not a substitute for checking the beef’s temperature.

Why should the roast rest before carving?
Resting gives the heat time to even out and helps the meat retain more of its juices when sliced. A 30-minute rest is built into this recipe’s timing. Keep the roast loosely tented, and carve just before serving for the juiciest slices.
