Slathered in a fragrant paste of fresh rosemary, thyme, minced garlic, and softened butter, this herb-crusted garlic butter prime rib roast uses a foolproof two-temperature oven method for a crackling mahogany crust and edge-to-edge rosy medium-rare beef.

Roasting a standing rib roast for Christmas or a special holiday dinner can feel intimidating given the price of the cut, yet the actual kitchen work is simpler than roasting a chicken. In our test kitchen, we compared reverse-searing against the classic initial high-heat blast and found that 20 minutes at 450°F (232°C) followed by gentle roasting at 325°F (163°C) builds the deepest herb-butter crust while keeping the eye of the rib meltingly tender.

Paired with a quick 10-minute red wine and beef broth pan jus made right in the roasting pan while the roast rests, this centerpiece commands the holiday table.

Why You’ll Love This Garlic Butter Prime Rib

Whipped rosemary, thyme, garlic, and Dijon butter forms a savory, aromatic bark as it roasts
Overnight dry-brining uncovered in the fridge draws moisture from the surface for superior browning
Two-stage oven temperature prevents the dreaded grey overcooked outer ring
Standing rib bones act as a natural roasting rack and insulate the meat from harsh bottom heat
Includes a rich, glossy red wine and beef pan jus made from the caramelized drippings

Key Ingredients (Overview)

Bone-In Standing Rib Roast: Ask your butcher for a 3-bone (6 to 7 lb / 2.7 to 3.1kg) prime or choice rib roast with the bones French-cut and tied back on with kitchen twine.
Kosher Salt & Coarse Black Pepper: Essential for seasoning generously 12 to 24 hours ahead.
Unsalted Butter: Softened to room temperature (1/2 cup / 113g) so it whips easily with the garlic and herbs.
Fresh Rosemary, Thyme & Sage: Finely minced woody herbs infuse the melting butter fat without burning during the low roast.
Fresh Garlic: Six cloves finely grated or minced into the compound butter.
Dijon Mustard & Horseradish: One Tablespoon of Dijon in the rub helps the herb crust adhere; prepared horseradish serves alongside.
Dry Red Wine & Beef Broth: Deglaze the roasting pan for an effortless steakhouse au jus.

Start by Dry-Brining and Whipping the Garlic Herb Butter

The day before roasting, pat the prime rib dry with paper towels, season all sides generously with 1 Tablespoon of kosher salt, and set it uncovered on a wire rack in the refrigerator overnight. This simple dry-brine seasons the beef deep into the center while drying the outer fat cap so it crisps instead of steaming.

Set the roast on the counter for 2 hours before cooking so the center loses its refrigerator chill—a cold roast cooks unevenly. Meanwhile, mash the softened butter, minced garlic, rosemary, thyme, Dijon mustard, and cracked black pepper in a bowl until smooth.

Why Pulling Prime Rib at 122°F (50°C) Guarantees Medium-Rare

Large multi-pound roasts store tremendous thermal energy in their outer layers. After you remove the prime rib from the oven and tent it with foil, carryover cooking raises the internal temperature by a full 8 to 10 degrees over 25 minutes. Pulling the roast when an instant-read thermometer in the thickest center reads 120–122°F (49–50°C) lands you at a steakhouse-perfect 130°F (54°C) medium-rare.

Culinary Insight: Three Rules for a Flawless Standing Rib Roast

Bring the roast to room temperature for 2 full hours: Putting a 38°F roast straight into a hot oven overcooks the outer 2 inches before the center warms.
Rely on a digital probe thermometer, not minutes per pound: Every oven and rib eye shape varies; aim for 122°F for medium-rare or 132°F for medium before resting.
Rest for 25 to 30 minutes before slicing: Letting the muscle fibers relax redistributes the savory juices so they stay in the beef rather than flooding the cutting board.

How to Make Herb-Crusted Garlic Butter Prime Rib

Place the butter-slathered roast bone-side down in a heavy cast-iron braiser or roasting pan. Roast at 450°F (232°C) for 20 minutes to sizzle and brown the garlic-herb crust, then reduce the oven temperature to 325°F (163°C) without opening the oven door.

Continue roasting at 325°F (163°C) for 1 hour 15 minutes to 1 hour 35 minutes (about 13 to 15 minutes per pound) until the center registers 122°F (50°C) for medium-rare. Transfer the roast to a warm carving board and tent loosely with foil for 25 minutes.

Spoon off excess fat from the roasting pan, leaving 2 Tablespoons of drippings and browned bits. Set the pan over medium-high heat, pour in the dry red wine to simmer by half, add the beef broth and a sprig of thyme, and simmer for 5 minutes. Snip the twine, slice the rib bones away in one piece, and carve the roast into thick slices.

The Final Result

Every slice reveals a deeply browned, herb-crusted exterior giving way to buttery, rosy-pink beef that cuts with the side of a fork.

Serve on warmed slate or ceramic plates drizzled with the red wine au jus alongside creamy horseradish sauce, Yorkshire puddings, or roasted garlic mashed potatoes.

Leftover prime rib keeps tightly wrapped in the refrigerator for up to 4 days and makes extraordinary French dip sandwiches dipped in warm leftover au jus.
