🔥 FULL INSTRUCTIONS

1. Prepare the Prime Rib Roast

  1. Remove roast from refrigerator 2 hours before cooking (room temp).
  2. Pat dry with a paper towel.
  3. Rub roast with olive oil and soft butter.
  4. Mix salt, pepper, garlic powder, onion powder, paprika, thyme, rosemary, parsley.
  5. Rub seasoning mixture all over the roast (sides, top, bottom).
  6. Press minced fresh garlic onto the outside.

2. Prepare Herb Butter Crust

  1. Mix butter, olive oil, rosemary, thyme, parsley, garlic.
  2. Spread generously over the entire roast.
  3. Place roast fat-side up in roasting pan (very important).

3. High-Heat Sear in Oven

  1. Preheat oven to 230°C / 450°F.
  2. Roast at high heat for 20 minutes to create crust.

4. Slow Roast Until Perfect

  • Reduce oven to 120°C / 250°F.
  • Cook until desired internal temperature (use meat thermometer):

Internal Temperature Guide

  • Rare: 48–50°C (118–122°F)
  • Medium-Rare (recommended): 54–57°C (130–135°F)
  • Medium: 60–63°C (140–145°F)

💡 A 6-lb roast usually takes 2–2.5 hours at low temperature.


5. Resting the Prime Rib

VERY IMPORTANT:

  • Remove roast from oven.
  • Tent loosely with foil.
  • Let rest 20–30 minutes.
  • Temperature will rise another 3–5°C while resting.

This makes the meat extremely juicy.


6. Slice & Serve

  1. Remove bones if attached (they slide off easily).
  2. Slice thick cuts (just like in the picture).
  3. Serve with:
    • au jus
    • horseradish sauce
    • mashed potatoes
    • roasted vegetables
