Why You'll Love It

Our top quality roast - this amazing boned and tied prime rib roast is SignaturePRIME, which is the top tier prime. Cook this to impress any guest! This prime rib roast is de-boned and the bone is tied back on to enhance flavor when cooking

Our SignaturePRIME® is hand-selected from the top tier of USDA Prime beef — a program that goes beyond standard Prime for exceptional marbling, tenderness, and taste. Each roast is wet-aged 21 days for peak flavor and juiciness.

Our Prime Rib Roast is available in 3-bone (≈6 lb) and 4-bone (≈8 lb) sizes. Plan for about 1 pound per person, making it perfect for serving 6–8 guests with the 3-bone roast or 8–10 guests with the 4-bone roast. Expertly hand-cut and beautifully marbled for rich, tender flavor in every bite.

This is a first cut prime rib — taken from the loin end rather than the chuck end — prized for its tenderness and fine marbling.

Average weights:
3 Bone - 6 lbs.
4 Bone - 8 lbs.
This is a natural product and weights can vary +/- 0.75 lbs.

How to Cook

  • Oven Roast

For a 6 lb prime rib (deboned and tied back on), here’s our recommended method:

Defrosting:
If frozen, thaw in the refrigerator for 3–4 days. Keep it in its original packaging and place on a tray. Do not thaw at room temperature.

Seasoning (day before or at least 2–4 hours ahead):
Once fully thawed, pat dry and season generously with kosher salt and cracked black pepper on all sides. Optional additions: garlic powder, fresh rosemary, or thyme. If time allows, leave uncovered in the fridge.

Cooking:
• Remove from fridge about 2 hours before cooking
• Preheat oven to 450°F
• Roast at 450°F for 20 minutes to develop a crust
• Reduce oven to 325°F and continue roasting until the internal temperature is 5–10°F below your final target:
– Pull at 115–120°F for rare (finishes ~120–125°F)
– Pull at 125–130°F for medium-rare (finishes ~130–135°F)

Plan on about 1¾–2 hours total, but always cook to temperature, not time.

Rest:
Remove from oven and rest 30 minutes. The tied bones help keep the roast juicy as it rests.

Bones & slicing:
After resting, simply snip the butcher’s twine and lift the bones away in one piece. Slice the roast across the grain and serve.
