The Ultimate Guide to Preparing the Perfect Prime Rib: A Christmas Tradition

Sliced prime rib.

Hey, I’m Jessica, a mom blogger residing in sunny Phoenix, AZ. During Christmas time, our family has a cherished tradition that involves my dad’s incredible prime rib recipe. Today, I’m excited to reveal this secret with you. It’s a recipe that remains just as tasty the day after when sliced cold between two pieces of bread as it does when served hot with all the delicious accompaniments. So, let’s get started and explore this mouthwatering dish!

A Little Bit About Prime Rib

Prime rib, also known as a rib roast, is a cut of beef from the primal rib, one of the nine primal cuts of beef. While the entire rib section comprises ribs six through 12, a standing rib roast may contain anywhere from two to seven ribs.

The Secret to a Perfect Prime Rib

The secret to preparing the perfect prime rib lies in two things: a reliable meat thermometer and your refrigerator. A meat thermometer ensures you don’t overcook your meat – something that would be a real tragedy. Also, let your meat reach room temperature before you start cooking, which helps it cook evenly.

How Long Should I Cook My Prime Rib For?

The cooking time for your prime rib depends on its weight and how you like your meat cooked. For instance, a 14-pound prime rib cooked to rare perfection would take about an hour and a half. But remember to factor in about 20 minutes of resting time after it’s out of the oven.

What Temperature Should Prime Rib Be Cooked To?

For prime rib, rare to medium-rare is ideal. Aim for an internal temperature of 120 to 125 degrees for rare, and 125 to 130 degrees for medium-rare. But, please don’t go beyond that or you’ll end up with a dry and tough piece of meat.

Prime Rib Vs. Ribeye: What’s the Difference?

Though they come from the same cut, prime rib and ribeye have differences in how they’re cut and cooked. Prime rib refers to the whole rib roast, while a ribeye is a steak cut from the roast before cooking.

Now, with all that said, let’s get into the nitty-gritty of how to prepare the perfect prime rib!


  • One whole ribeye (boneless or bone-in) – about 13-14 pounds
  • A small bowl of minced garlic
  • A blend of rosemary, sage and thyme
  • Salt and crushed tri-color peppercorns
  • Worcestershire sauce and soy sauce
  • Plenty of olive oil

Step-by-Step Guide to Making Perfect Prime Rib

Step 1: Marination

Mix the garlic, rosemary, sage, thyme, salt, and pepper together in a small bowl. Pat this mixture over the entire roast. Make a deep cut down the middle of the roast (keep it parallel with the bones), place it in a plastic roasting bag, and pour the Worcestershire and soy sauce into the bag, focusing on the cut in the roast. Tie the bag, refrigerate the roast, and let it marinate for at least 2 hours, turning it occasionally.

Step 2: Preparing for Roasting

Remove the roast from the refrigerator and let it come to room temperature. This should take about 1 to 2 hours. After that, take out the roast from the bag and discard the marinade. Place the roast in a roasting pan, fat side up.

Step 3: Roasting

Preheat your oven to 500 degrees F (260 degrees C). Bake the roast in the preheated oven for 15 minutes, then lower the heat to 350 degrees F (175 degrees C) and continue cooking until the internal temperature reaches 145 degrees F (65 degrees C). This should take about 1 hour. After that, let the roast stand for 20 minutes before slicing.

What to Do With Leftover Prime Rib?

Leftover prime rib can be used in a variety of dishes. Thinly slice it for roast beef sandwiches, cube it for beef stew or steak pot pie, or use it in beef stroganoff. The possibilities are endless!
