What Is Prime Rib?

Prime rib (also known as a standing rib roast) is a cut from the primal rib section of the cow. It includes some of the most tender and flavorful meat due to its fat content and muscle structure.

Despite the name, “prime” rib doesn’t mean the meat is USDA Prime grade. You can find it in Choice or Prime grades—Prime being more marbled and flavorful (and expensive).

Choosing the Right Prime Rib Cut

When selecting a prime rib roast, here’s what to keep in mind:

Bone-in vs Boneless

• Bone-in: More flavor, better insulation while cooking, juicier meat.
• Boneless: Easier to carve and cooks slightly faster.

How Much Per Person?

A good rule of thumb:

• Bone-in: 1 rib for every 2 people
• Boneless: 1/2 lb to 3/4 lb per person

How to Prepare Prime Rib for Cooking

Step 1: Let It Come to Room Temperature

Take your roast out of the fridge at least 2-3 hours before roasting. This helps it cook evenly.

Step 2: Season Generously

The best prime rib rub includes:

• Kosher salt
• Fresh cracked black pepper
• Garlic powder or fresh garlic
• Fresh herbs like rosemary or thyme

Rub it all over the meat and let it sit for flavor to absorb. You can season it a full 24 hours in advance for even better flavor.

Cooking Methods: Slow and Steady Wins the Flavor

1. Reverse Sear Method (Low and Slow)

• Roast at 250°F until internal temp hits 120°F
• Then sear at 500°F for 10 minutes to crisp the crust

2. Traditional High-Low Method

• Start at 450°F for 20 minutes to develop crust
• Reduce to 325°F and roast until done
