No holiday spread or special occasion is truly complete without a centerpiece that makes everyone stop and stare. If you’ve been intimidated by cooking a prime rib before, put those fears aside. Using a simple “high-to-low” temperature method and a decadent compound butter, we’re going to ensure your roast is juicy, tender, and packed with flavor.
Follow along as we break down the steps to achieving that perfect medium-rare center and a savory, herb-crusted bark.
The Ingredients
The Meat
- 5 to 6 lb Prime Rib Roast: Look for good marbling. We recommend a bone-in roast for better flavor and more even cooking.
The Dry Brine & Seasoning
- Kosher Salt: Essential for drawing out moisture and locking in flavor.
- All-Purpose Seasoning: A blend of garlic powder, onion powder, and black pepper.
The Signature Compound Butter
- 2 sticks Unsalted Butter: Make sure it is room temperature for easy mixing.
- Fresh Herbs: Rosemary and Thyme.
- Aromatics: 6 cloves of Garlic and 2 small Shallots.
- Flavor Boosters: A dash of Worcestershire sauce, smoked paprika, and a drizzle of olive oil.
Step 1: Prep Like a Pro
The secret to a great prime rib starts long before the oven is turned on. First, take a sharp knife and partially remove the bone. You aren’t cutting it all the way off; you’re just creating a “pocket” so you can get seasoning deep inside the meat.
Once prepped, apply a heavy application of Kosher salt. If you have the time, do this the night before and let it sit in the fridge uncovered. This “dry brine” ensures the seasoning penetrates deep into the muscle.
Pro Tip: Always let your meat sit on the counter for about 45–60 minutes before cooking. Putting a cold roast into a hot oven is a recipe for uneven cooking!
Step 2: The Compound Butter Massage
While your roast comes to room temperature, create your herb butter. Finely mince your garlic, shallots, and herbs (or pulse them in a food processor with a little oil). Fold this mixture into your softened butter along with the Worcestershire and paprika.
Once mixed, slather the butter all over the roast. Don’t be shy—this butter is what creates that beautiful, dark, flavorful “bark” on the outside of the meat. Use butcher’s twine to tie the bones back tight against the meat to keep the roast’s shape.
Step 3: The “500-Degree” Method
We use a two-stage cooking process to get the best of both worlds: a seared exterior and a perfectly pink interior.
- The Blast: Preheat your oven to 500°F. Roast the meat for exactly 5 minutes per pound. (For a 5lb roast, that’s 25 minutes).
- The Slow Roast: Lower the temperature to 325°F. Continue cooking for 12–14 minutes per pound until your meat thermometer hits your desired doneness (around 130°F for medium-rare).
Step 4: The Most Important Step—The Rest
When the roast comes out of the oven, it will be tempting to slice into it immediately. Resist the urge! Let the meat rest for at least 15 to 20 minutes. This allows the juices to redistribute. If you cut it too soon, all that delicious flavor will run out onto the cutting board instead of staying in the meat.
The Results
Slice it up, serve it with a side of horseradish cream or au jus, and get ready for the compliments to roll in. It’s tender, rich, and worth every bit of effort.
