Ingredients

• 1 bone-in prime rib roast (6 to 8 lbs / 2.7 to 3.6kg)
• 4 tablespoons softened butter
• 4 cloves garlic, minced
• 2 tablespoons fresh rosemary, chopped (or 1 tablespoon dried)
• 2 tablespoons fresh thyme, chopped (or 1 tablespoon dried)
• 1 tablespoon coarse salt
• 1 tablespoon black pepper
• 1 teaspoon onion powder

Equipment Needed

• Roasting pan with rack
• Meat thermometer (this is essential)
• Sharp knife
• Cutting board
• Small bowl (for mixing seasonings)
• Aluminum foil
• Kitchen twine (optional, if bones are cut)

Instructions

Step 1: Take the roast out of the fridge 2 to 3 hours before cooking. It needs to come to room temperature. Cold meat cooks unevenly.

Step 2: Preheat your oven to 450°F (230°C).

Step 3: Pat the roast completely dry with paper towels. Moisture prevents browning.

Step 4: In a small bowl, mix together the softened butter, minced garlic, rosemary, thyme, salt, pepper, and onion powder.

Step 5: Rub this mixture all over the roast. Cover the top and sides completely. Press it into the meat.

Step 6: Place the roast bone-side down on a rack in your roasting pan. The bones act as a natural rack.

Step 7: Put the roast in the preheated 450°F oven. Cook for 15 minutes. This creates a nice brown crust.

Step 8: After 15 minutes, reduce the oven temperature to 325°F (165°C). Do not open the door. Just turn down the heat.

Step 9: Continue cooking at 325°F. Plan for about 15 to 18 minutes per pound for medium-rare.

Step 10: Start checking the temperature after 1.5 hours. Insert a meat thermometer into the thickest part without touching bone.

Step 11: Remove the roast when it reaches 120°F (49°C) for rare, 125°F (52°C) for medium-rare, or 130°F (54°C) for medium. The temperature will rise as it rests.

Step 12: Take the roast out of the oven. Tent it loosely with aluminum foil.

Step 13: Let it rest for at least 30 minutes. This is critical. The juices redistribute through the meat during this time.

Step 14: Remove the bones by cutting along the bone line with a sharp knife. Slice the meat against the grain into thick slices.

Step 15: Serve immediately with the bones on the side for people who want them.

Substitutes & Swaps

Fresh herbs: Dried herbs work fine. Use half the amount since dried herbs are more concentrated.

Butter: Olive oil works instead. The butter adds richness but oil still creates a good crust.

Bone-in roast: Boneless works too. Cooking time is slightly shorter. Check temperature early.

Garlic: Garlic powder works if you do not have fresh. Use 1 teaspoon instead of 4 cloves.

Variations

Horseradish Crusted Prime Rib: Mix 2 tablespoons prepared horseradish into the butter mixture. Sharp and delicious.

Peppercorn Crusted Prime Rib: Coat the roast in crushed mixed peppercorns after applying the butter. Press them in well.

Mustard Herb Prime Rib: Spread 2 tablespoons Dijon mustard over the roast before adding the herb butter.

Coffee Rubbed Prime Rib: Add 1 tablespoon finely ground coffee to the seasoning mix. It adds deep savoury flavour.

Tips & Tricks

Bring meat to room temperature. This is the most important step. Cold meat in the oven cooks unevenly. The outside overcooks before the inside is done.

Use a meat thermometer. This is not optional. Guessing leads to overcooked or undercooked meat. Temperature is the only way to know for sure.

Do not skip the resting time. Thirty minutes minimum. The roast continues cooking and the juices settle. Cut it too early and all the juice runs out.

Save the drippings. The fat and juices in the pan make incredible gravy or au jus. Do not throw them away.

Plan your timing. Work backwards from when you want to eat. Add cooking time plus resting time plus 15 minutes buffer.

Ask your butcher for help. Tell them how many people you are feeding. They will choose the right size roast and can trim it properly.

Let it rest bone-side down. This keeps the heat in and protects the meat while it rests.

Frequently Asked Questions (FAQs)

How much prime rib per person?

Plan for about 1 pound per person if it is bone-in. For boneless, plan for ½ to ¾ pound per person.

What temperature should prime rib be?

For medium-rare (the best way), remove it at 125°F. It will rise to 130-135°F while resting. For medium, remove at 130°F.

Can I cook prime rib the day before?

Not recommended. Prime rib is best served fresh. You can prep and season it the day before but cook it the day you serve it.

Why do I need to rest the meat?

Resting lets the juices redistribute. If you cut it right away, all the juice runs out and the meat is dry. Patience pays off.

Can I use a different cut of beef?

Prime rib is also called standing rib roast. Ribeye roast works the same way. Other cuts need different cooking methods.

What if I do not have a roasting rack?

Make a bed of roughly chopped carrots, celery, and onions. Place the roast on top. The vegetables keep it off the bottom of the pan.

How do I make au jus from the drippings?

Pour off most of the fat. Add 1 cup beef broth to the pan. Scrape up the browned bits. Simmer for 5 minutes. Strain and serve.
