Lawry's Prime Rib Roast Recipe: Au Jus Soaked, Fork-Tender Beef

Mastering a Lawry's prime rib roast recipe means achieving that signature au jus-soaked tenderness that turns every bite into a restaurant-quality experience. The secret lies in precise seasoning, slow roasting, and letting the meat rest—technique details that transform tough cuts into melt-in-your-mouth perfection.

I've perfected this method over years of holiday dinners, ensuring the crust stays rich and caramelized while the interior remains fork-tender.

This recipe delivers restaurant-quality results with just five key ingredients: prime rib roast, Lawry's seasoning blend, olive oil, and a simple au jus mixture. The process requires patience—about 3 hours in the oven—but the outcome is worth every minute.

The seasoning creates a deep, savory crust, while the au jus infuses the meat during resting, ensuring every slice is juicy and flavorful. No fancy equipment needed, just a roasting pan and a meat thermometer for precision.

By the time you serve this prime rib, your guests will be impressed by the fork-tender beef that practically falls apart at the touch of a fork. The au jus reduces into a rich, savory sauce that coats every bite, while the crust remains perfectly seared.

This is the kind of centerpiece dish that elevates any holiday or special occasion dinner. Let’s get started on creating a prime rib that rivals the best steakhouses.

The beauty of this recipe is its versatility—pair it with classic sides like roasted potatoes, garlic mashed potatoes, or a fresh green salad. The au jus can also be used as a dipping sauce for crusty bread.

Once you master this technique, you’ll never buy pre-made prime rib again. Here’s how to make it perfectly every time.

Ingredients for lawry's prime rib roast

Five essential ingredients transform a simple roast into restaurant-quality prime rib with signature au jus tenderness.

The prime rib roast is non-negotiable for this recipe—bone-in, center-cut delivers the best flavor and texture. Purchase from a reputable butcher or specialty store like D'Artagnan or your local high-end grocer for optimal marbling. A 6-pound roast serves 6-8 generously, with leftovers perfect for sandwiches. The Lawry's seasoned salt is critical; its blend of celery salt, garlic, and onion powder creates the signature crust. For the au jus, Lawry's brand mix ensures consistent flavor, though homemade blends with beef bouillon, Worcestershire, and a splash of red wine work equally well.

No Lawry's seasoned salt? Create your own blend with 2 tbsp kosher salt, 1 tsp garlic powder, 1 tsp onion powder, and 1/2 tsp celery salt. Substitute the red wine with an additional 1/2 cup beef broth if needed, though the acidity enhances the au jus depth. For the butter, European-style unsalted like Plugrá or President melts more cleanly. Fresh herbs can be swapped for 1 tbsp dried rosemary and 1 tsp dried thyme, though fresh infuses superior aroma. The onions and garlic should be yellow, firm, and unblemished—no wilted or sprouting varieties.

Prime rib benefits from 24 hours of dry-brining in the refrigerator before roasting, enhancing moisture retention. Store the au jus base ingredients separately in airtight containers for up to 1 week, while the Lawry's seasoning blend lasts indefinitely. Leftover prime rib reheats beautifully in a 275°F oven for 20 minutes, wrapped in foil with a splash of beef broth. The au jus reduces further when reheated, so keep a small amount of the original beef broth on hand to thin it if needed.

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

The secret to fork-tender prime rib lies in precise timing and moisture retention. Follow these steps to achieve a perfectly cooked roast with rich au jus.

Remove the 6 lb prime rib roast from the refrigerator and let it sit at room temperature for 30 minutes to ensure even cooking. Pat the surface dry with paper towels, focusing on the fat cap and any moisture pockets. This step is crucial for developing a proper crust during roasting.

In a small bowl, combine 2 tbsp Lawry's Seasoned Salt with 1 tsp extra Diamond Crystal Kosher Salt and 1 tsp freshly cracked Black Peppercorns. Rub this mixture evenly over the entire surface of the roast, including the fat cap. For extra flavor, insert the tied bundle of 1 sprig fresh rosemary and 2 sprigs fresh thyme into the roast's cavity. Let the seasoned roast rest uncovered in the refrigerator for at least 4 hours or overnight. This dry-brining process enhances flavor penetration and creates a flavorful crust.

Preheat your oven to 450°F and place a rack in a roasting pan. Remove the prime rib from the refrigerator and let it sit at room temperature for 15 minutes before cooking. Heat 0.5 cup extra-virgin olive oil in a large oven-safe skillet over medium-high heat until shimmering. Sear the roast on all sides for 3-4 minutes per side until deeply browned. Transfer the skillet to the preheated oven and roast for 20 minutes to render the fat and begin cooking.

Reduce the oven temperature to 325°F and continue roasting for 2-2.5 hours, or until the internal temperature reaches 130°F on a meat thermometer. This low-and-slow cooking method ensures the meat remains tender and juicy. Baste the roast with 0.25 cup cold unsalted butter, melted and strained, every 30 minutes to keep it moist and flavorful.

While the prime rib roasts, prepare the au jus base. In a large saucepan, combine 1 whole sliced yellow onion, 6 minced garlic cloves, 2 cups beef broth, 0.5 cup red wine, and 1 package beef au jus mix. Bring the mixture to a simmer over medium heat and cook for 15 minutes, allowing the flavors to meld and the liquid to reduce slightly. Strain the mixture through a fine-mesh sieve to remove any solids, and keep the liquid warm.

Return the strained au jus to the saucepan and add 0.5 cup extra-virgin olive oil. Whisk the mixture gently to combine, creating a velvety sauce. Keep the au jus warm on low heat until ready to serve, ensuring it maintains a smooth consistency.

Once the prime rib reaches an internal temperature of 130°F, remove it from the oven and transfer it to a cutting board. Tent loosely with aluminum foil and let it rest for 30 minutes. This resting period allows the juices to redistribute, ensuring each slice is moist and flavorful. Use a sharp carving knife to slice the roast into ½-inch thick pieces against the grain.

To serve, spoon the warm au jus over the sliced prime rib, garnishing with additional fresh rosemary and fresh thyme for a touch of elegance. The resulting dish should feature tender, juicy beef with a rich, flavorful au jus that complements every bite.

Troubleshooting great lawry's prime rib roast

Uneven Cooking

If your prime rib emerges with cold spots or overcooked edges, the issue is almost always uneven heat distribution. I’ve found that roasting pans with thick bottoms (like All-Clad Stainless Steel) help distribute heat more evenly.

Place the roast fat-side up on the rack to prevent steam buildup, which can slow cooking. For extra insurance, use an oven thermometer—many home ovens run 25-50°F hotter or colder than set. Adjust your target temp to 300°F if your oven runs hot. 🌡️

Dry or Tough Meat

Prime rib is forgiving, but overcooking or skipping the rest are the top culprits for dryness. Remove the roast when it hits 130°F internal temp—it’ll rise to 140-145°F during resting. If you’re worried about doneness, use a meat probe thermometer like Thermoworks Smoke to monitor accuracy.

Never skip the 30-minute rest—juices need time to redistribute. For extra moisture, baste with melted butter every 30 minutes during roasting. 💡

Weak or Watery Au Jus

A watery au jus usually means the liquid wasn’t reduced enough or the base wasn’t flavorful. Always simmer the au jus uncovered to thicken it naturally—don’t let it boil.

For depth, deglaze the roasting pan after removing the meat with ½ cup red wine and scrape up all the browned bits. If your au jus is still thin, reduce it further on the stove or whisk in 1 tsp cornstarch mixed with cold water. 🍷

Fat Not Rendering Properly

If the fat cap isn’t crisp and golden, your oven temp might be too low or the roast wasn’t seared enough. Start with a 450°F sear to render fat quickly, then drop to 325°F for low-and-slow cooking.

For stubborn fat, score the cap in a crosshatch pattern before seasoning—this helps it crisp without overheating the meat. If fat pools in the pan, tilt the roasting rack slightly to let it drip away. ⚡

Crust Falling Off

A crumbly crust happens when the seasoning isn’t dry enough or the meat isn’t seared properly. Pat the roast completely dry before seasoning—even a damp spot can prevent crust formation. For extra adhesion, press the seasoning blend firmly into the meat, especially on the fat cap.

If the crust still fails, try coating the roast lightly with flour before searing to help the seasoning stick. 🧂
