Ingredients for lawry's prime rib roast

Six essential ingredients transform a prime rib into a showstopping holiday centerpiece.

The prime rib roast is non-negotiable for this recipe—center-cut, bone-in, and 1.25 inches thick delivers the perfect balance of tenderness and crust. Purchase from a trusted butcher or Whole Foods for optimal marbling and freshness. A 5-pound roast serves six generously, with leftovers ideal for sandwiches. Look for vibrant red color and visible fat marbling—this ensures succulence during roasting. If your roast arrives pre-wrapped in plastic, pat it dry thoroughly with paper towels before seasoning to maximize crust development. Costco often carries high-quality prime rib in bulk, perfect for holiday gatherings.

For the herb butter, use unsalted butter chilled until firm—this prevents excessive melting during searing. Fresh herbs like rosemary and thyme elevate the flavor profile; dried substitutes work at half the quantity, but the aroma is noticeably inferior. The beef broth should be low-sodium to avoid over-salting the au jus, and Cabernet Sauvignon is ideal for its acidity and depth. Substitute with Pinot Noir if needed, but avoid sweet wines. The balsamic vinegar adds complexity—aged 10+ years provides a richer, caramelized note. For the au jus, yellow onion and carrots form the aromatic base; frozen vegetables work in a pinch but lack freshness. Diamond Crystal kosher salt is preferred for its coarse texture, which adheres better to the meat.

Store the prime rib roast uncovered on a wire rack in the fridge for 24 hours before cooking to enhance dry-brining. The herb butter keeps for up to 1 week in an airtight container in the refrigerator, or 3 months frozen in portions. Beef broth and red wine can be prepped ahead and refrigerated for up to 5 days, while the au jus reheats beautifully and tastes even better the next day. For large gatherings, double the au jus ingredients—it’s the star of the meal and always disappears first.

Step-by-step instructions for Lawry's prime rib roast recipe

Mastering this technique guarantees a restaurant-quality prime rib with flawless crust and melt-in-your-mouth tenderness.

Remove the prime rib roast from the refrigerator and place it on a wire rack set over a baking sheet. Pat the surface completely dry with paper towels—this critical step ensures maximum browning. Using your hands, gently press the 0.5 cup kosher salt and 1 tablespoon freshly ground black pepper into the meat, working it into all surfaces including the fat cap. The salt will begin drawing out moisture immediately, so work quickly.

In a small bowl, combine the 0.25 cup finely chopped fresh rosemary, 0.25 cup finely chopped fresh thyme, and 8 minced garlic cloves. Mix well, then rub this herb mixture evenly over the entire surface of the prime rib. Let the seasoned roast sit at room temperature for 1 hour before roasting—this allows for even cooking and prevents temperature shock when it enters the hot oven.

In a small mixing bowl, combine the 0.5 cup cold unsalted butter with 1 tablespoon balsamic vinegar and 1 tablespoon finely chopped fresh rosemary. Mix until just combined, then shape into a log and wrap in plastic wrap. Chill until ready to use. This herb butter will create an irresistible crust while basting the meat.

Preheat your oven to 450°F with the rack positioned in the lower third of the oven. Place the prime rib roast fat-side up on a rack in a roasting pan. Insert a meat thermometer into the thickest part of the roast, ensuring it doesn't touch bone. Roast for 20 minutes to render the fat and begin searing. After 15 minutes, carefully remove the herb butter from the refrigerator and begin basting the roast every 5 minutes with the melted butter, tilting the pan to coat all surfaces.

After the initial 20-minute sear, reduce the oven temperature to 325°F. Continue roasting the prime rib, basting every 15 minutes with additional melted herb butter, until the internal temperature reaches 120-125°F for medium-rare. This typically takes an additional 1.5 to 2 hours, depending on your oven's calibration. The exterior should develop a deep mahogany crust while the interior remains tender and pink.

During the final 30 minutes of roasting, prepare the au jus by combining 2 tablespoons extra-virgin olive oil, 1 diced yellow onion, and 3 sliced carrots in a saucepan. Cook over medium heat until the vegetables soften (8-10 minutes). Add 2 cups beef broth and 0.5 cup red wine, then simmer uncovered until reduced by half (15-20 minutes). Strain through a fine-mesh sieve before serving.

When the prime rib reaches the target internal temperature, remove it from the oven and transfer to a cutting board. Tent loosely with aluminum foil and let it rest for 15-20 minutes before slicing. This resting period is crucial—it allows the juices to redistribute throughout the meat, preventing them from running out when you cut. The temperature will rise an additional 5°F during resting, so don't worry if it climbs to 125-130°F.

Using a sharp carving knife, slice the prime rib against the grain into ½-inch thick slices. Arrange the slices on a warm platter and ladle the reduced au jus over the top. Serve immediately with the remaining au jus on the side for dipping. Each slice should be perfectly pink in the center with a crisp, herb-infused crust that gives way to incredibly tender meat.

Common mistakes when making perfect results

Skipping the Dry-Brining

One of the most common mistakes is skipping the 24-hour dry-brining step. This process allows the salt to penetrate deeply, enhancing flavor and moisture retention. Without it, your prime rib may develop a weaker crust and lose juices during cooking.

I always place my roast uncovered on a wire rack in the fridge—this maximizes surface area for even salt absorption. 🧂

Overlooking Room Temp

Pulling a cold prime rib straight from the fridge into a hot oven creates an uneven cooking environment. Let your roast sit at room temperature for at least 1 hour before roasting.

This ensures even heat penetration and prevents the exterior from overcooking while the center remains underdone. I set a timer to remind myself—this simple step makes all the difference. ⏰

Incorrect Internal Temp

Many cooks rely on time rather than temperature, leading to overcooked or undercooked prime rib. Use a meat thermometer to monitor the internal temperature—120-125°F for medium-rare is ideal.

The thermometer should be inserted into the thickest part, avoiding bone. I recommend the ThermoWorks Smoke for accuracy. Without precise temperature control, you risk dry, tough meat. 🌡️

Skipping the Resting Phase

Cutting into prime rib immediately after roasting causes juices to escape, leaving you with dry slices. Always let the roast rest for 15-20 minutes before slicing. This allows juices to redistribute, ensuring each bite is moist and flavorful. I cover it loosely with foil to retain heat while resting. 💡

Basting Too Frequently

While basting adds flavor, overdoing it can lead to uneven cooking. Baste every 15 minutes during the low-and-slow phase, not constantly. Excessive basting disrupts the oven's temperature and can create steam, which prevents proper crust formation. I use a basting brush to spread the herb butter evenly. ✨

Using the Wrong Cut

Not all prime rib is created equal. For this recipe, you need a center-cut, bone-in roast that's 1.25 inches thick. Thinner cuts or those from the outer edges won't develop the same rich flavor or tenderness.

I always specify this to my butcher—I've learned the hard way that cheaper, leaner cuts just don't deliver the same results. 🥩
