Garlic Herb Prime Rib with Au Jus — For the Woman Who Finally Gets to Sit Down

Mama’s last night in town before flying back to Sapulpa Sunday morning. The household had been doing simple weeknight dinners all week so I could write — a sheet-pan chicken Tuesday, the no-bake-energy-bites-and-tomato-soup Wednesday, leftovers Thursday, take-out Indian Friday because everyone was tired. Saturday Mama said over breakfast that she didn’t want a simple dinner for her last night. She wanted to sit at a properly-set table with the cloth napkins from the cabinet and the good plates and food that announced itself in the way Sunday-dinner food announces itself.

I asked her what she wanted. She said prime rib with au jus. The cafe makes prime rib for Saturday-night-special service in the colder months and Mama had been thinking about it for the past two weeks. The cafe was closed Sunday so she wouldn’t get to eat the cafe’s version this trip.

Saturday afternoon I made garlic herb prime rib with au jus and we ate at the dining table Saturday night with the cloth napkins out, the apartment’s good plates from the wedding-registry inventory, the candles Aunt Linda had given us as a Christmas gift, and a bottle of red wine Dustin’s parents had sent up for Mama’s visit. Brayden and Wyatt sat at the table with us, both in cleaner shirts than usual. Brayden understood that this was a special-dinner Saturday. Wyatt didn’t but participated anyway.

The technique: a four-pound boneless prime rib roast (the bone-in version is more dramatic but the boneless is easier to slice for a small dinner; for Mama I went boneless), salted heavily on every surface twenty-four hours in advance and refrigerated uncovered (the dry-brine pulls moisture to the surface, then reabsorbs it with the salt, and dries the exterior for proper sear).

The herb butter: a half-cup of softened butter mashed with eight cloves of garlic minced very fine, two tablespoons of fresh chopped rosemary, two tablespoons of fresh chopped thyme, a tablespoon of fresh chopped sage, salt, pepper. Spread generously across all surfaces of the roast.

The cook: the same Cook’s Illustrated reverse-sear method I’d been using since the 2018 Christmas Eve prime rib. Roast at five hundred for fifteen minutes to set the crust. Drop the oven to two-fifty and roast for an hour and forty-five minutes for medium-rare (internal temp one-twenty-five at the deepest part). Rest twenty minutes under foil.

The au jus: while the roast rests, in a small saucepan combine the pan drippings, a half-cup of dry red wine, two cups of low-sodium beef broth, a tablespoon of Worcestershire, a sprig of fresh thyme, salt, pepper. Simmer ten minutes until reduced by a third. Strain through a fine-mesh sieve.

The roast carved into thick slices on a wooden cutting board at the table (Mama had specifically requested the carving-at-the-table presentation). Plated with the au jus poured generously alongside, mashed potatoes, asparagus, and the rolls Mama had baked Saturday morning before her last cafe FaceTime check-in.

Mama ate two slices and a generous spoonful of the au jus. She didn’t cry but she did the throat-tightening thing. She told me at the table that this was the kind of dinner her own mother had stopped making after Mama’s daddy died — the kind of properly-set-table-prime-rib dinner that requires both an occasion and a household that has the time to set the table properly. She said the dinner felt like a small kind of completion.

Mama flew home Sunday morning. The household reset to four. Brayden asked at breakfast when Gama was coming back. I told him soon. She probably will.

Dry-brine twenty-four hours. Herb butter all over. Reverse-sear: five hundred fifteen minutes, two-fifty an hour forty-five. Au jus from drippings. Here’s the build.

Garlic Herb Prime Rib with Au Jus

Prep Time: 20 minutes | Cook Time: 2 hours 30 minutes | Total Time: 2 hours 50 minutes (plus overnight dry-brine, optional) | Servings: 8

Ingredients

• 1 bone-in prime rib roast (6–7 lbs), about 3 bones
• 6 cloves garlic, minced
• 2 tablespoons fresh rosemary, finely chopped
• 2 tablespoons fresh thyme leaves
• 2 tablespoons fresh flat-leaf parsley, finely chopped
• 3 tablespoons olive oil
• 2 tablespoons kosher salt
• 1 1/2 teaspoons freshly cracked black pepper
• 1 teaspoon smoked paprika
• For the Au Jus:
• Pan drippings from the roast
• 1/2 cup dry red wine (such as Cabernet Sauvignon)
• 2 cups beef broth (low sodium)
• 1 teaspoon Worcestershire sauce
• Salt and pepper to taste

Instructions

1. Dry-brine (optional but recommended). The night before, pat the prime rib completely dry with paper towels. Rub all sides generously with kosher salt. Place uncovered on a wire rack set over a rimmed baking sheet and refrigerate overnight. This deepens the crust and flavor significantly.
2. Make the herb paste. Remove the roast from the refrigerator 1 to 1 1/2 hours before cooking to take the chill off. Preheat your oven to 450°F. In a small bowl, combine the minced garlic, rosemary, thyme, parsley, olive oil, black pepper, and smoked paprika into a thick paste.
3. Apply the rub. Pat the roast dry once more. Using your hands, press the garlic herb paste firmly and evenly over the entire surface of the roast, including the sides and between the bones if possible. Place the roast bone-side down in a heavy roasting pan or cast iron skillet.
4. High-heat sear. Roast at 450°F for 20 minutes uncovered. This creates the deep, golden-brown crust that seals in the juices and builds flavor.
5. Low and slow roast. Without opening the oven, reduce the temperature to 325°F. Continue roasting until an instant-read thermometer inserted into the thickest part (away from bone) reads 120°F for rare, 130°F for medium-rare (recommended), or 135°F for medium. This typically takes 1 hour 45 minutes to 2 hours for a 6–7 lb roast, but always go by temperature, not time.
6. Rest the roast. Transfer the prime rib to a cutting board and tent loosely with aluminum foil. Let it rest for at least 20–30 minutes. The internal temperature will rise another 5–10 degrees during resting. Do not skip this step — it is what makes the meat juicy.
7. Make the au jus. While the roast rests, place the roasting pan directly over medium heat on the stovetop (use two burners if needed). Pour in the red wine and scrape up all the browned bits from the bottom of the pan with a wooden spoon. Let the wine reduce by half, about 2 minutes. Add the beef broth and Worcestershire sauce. Bring to a simmer and cook for 5–8 minutes until slightly reduced and deeply flavored. Skim off excess fat if desired. Taste and adjust salt and pepper. Strain through a fine mesh sieve into a warmed serving vessel.
8. Carve and serve. Slice the prime rib between the bones for bone-in portions, or slice crosswise into 3/4-inch to 1-inch thick slices for boneless-style serving. Arrange on a warmed platter and serve immediately alongside the hot au jus for dipping or pouring.
