Ingredients: 1 (6 to 7-pound) bone-in prime rib roast; 2 tablespoons kosher salt; 1 tablespoon freshly cracked black pepper; 2 tablespoons garlic powder; 1 tablespoon onion powder; 2 tablespoons fresh rosemary, finely chopped; 2 tablespoons fresh thyme, finely chopped; 1/4 cup olive oil; 1 tablespoon Dijon mustard (optional)

Few dishes capture the essence of a special occasion like a perfectly cooked Classic Prime Rib. With its deeply flavorful crust and juicy, rosy center, this impressive roast brings elegance and heartiness to your table. Whether you’re preparing a holiday feast or simply indulging in a weekend treat, prime rib is a showstopper that requires little more than seasoning, patience, and love.

The secret to success lies in its simplicity. This cut of beef is already rich and tender, so the goal is to enhance, not mask, its natural flavors. A slow roast followed by a high-heat sear ensures the ideal texture—a tender interior with a crisp, golden exterior. Paired with your favorite sides, it’s a celebration in every bite.

What Cut Should I Buy for Classic Prime Rib?

When shopping for prime rib, look for a bone-in rib roast with plenty of marbling. The bones insulate the meat as it cooks, resulting in more flavor and moisture. A three-bone roast is perfect for feeding 6 to 8 guests, while a larger cut can serve a holiday crowd with leftovers to spare.

Ingredients for the Classic Prime Rib

1 (6 to 7-pound) bone-in prime rib roast
2 tablespoons kosher salt
1 tablespoon freshly cracked black pepper
2 tablespoons garlic powder
1 tablespoon onion powder
2 tablespoons fresh rosemary, finely chopped
2 tablespoons fresh thyme, finely chopped
1/4 cup olive oil
Optional: 1 tablespoon Dijon mustard

How To Make the Classic Prime Rib

Step 1: Prep the Roast

Pat the prime rib dry with paper towels and let it sit at room temperature for at least 2 hours. This ensures even cooking.

Step 2: Season Generously

In a small bowl, combine salt, pepper, garlic powder, onion powder, herbs, and olive oil (and mustard if using). Rub the mixture all over the roast, pressing it into every crevice.

Step 3: Low and Slow Roast

Preheat your oven to 250°F (120°C). Place the roast fat-side up on a rack in a roasting pan. Roast for 3 to 3.5 hours, or until the internal temperature reaches 118°F for rare, 125°F for medium-rare.

Step 4: Rest Before Searing

Remove the roast and tent loosely with foil. Let rest for 30 minutes. Increase the oven temperature to 500°F (260°C).

Step 5: Final Sear

Return the roast to the oven for 10-15 minutes until the crust is browned and crisp. Slice and serve immediately.

How to Serve and Store Your Prime Rib

Classic Prime Rib is best served freshly carved with simple sides like garlic mashed potatoes, roasted vegetables, or creamed spinach. Drizzle with au jus or horseradish cream for a restaurant-quality touch.

Store leftovers tightly wrapped in foil or in an airtight container in the fridge for up to 4 days. To reheat, use a low oven (275°F) until just warmed through—avoid microwaving to preserve texture.

Frequently Asked Questions

How much prime rib do I need per person?

Plan for about 1 pound per adult. If serving children or multiple sides, you can stretch it a bit further.

Can I cook prime rib ahead of time?

You can slow-roast a day ahead and then reheat and sear just before serving, but fresh is always best.

What internal temperature should I aim for?

118°F for rare, 125°F for medium-rare, and 135°F for medium. Use a meat thermometer for accuracy.

Do I need to tie the roast?

If your roast is not already tied, trussing helps it hold shape and cook evenly. Ask your butcher or do it yourself with kitchen twine.

Can I make it without bones?

Yes, boneless prime rib is still delicious but cooks faster and may be slightly less flavorful.
