👩🍳 STEP-BY-STEP INSTRUCTIONS (DETAILED + FOOLPROOF)
🔥 STEP 1: PREP THE ROAST (THE FLAVOR FOUNDATION)
Pat your rib roast completely dry with paper towels. Moisture is the enemy of a good crust.
Mix salt, pepper, garlic powder, onion powder, rosemary, and thyme in a bowl. Rub olive oil all over the meat, then massage the seasoning generously into every surface.
👉 Pro Tip: Season the roast at least 12 hours in advance and refrigerate uncovered. This builds deeper flavor and a better crust.
🕒 STEP 2: BRING TO ROOM TEMPERATURE
Remove the roast from the fridge and let it sit for 1–2 hours before cooking.
👉 This ensures even cooking.
❌ Cold meat = uneven doneness (outer overcooked, center undercooked)
🔥 STEP 3: PREHEAT AND ROAST
Preheat oven to 220°C (425°F).
Place roast bone-side down in roasting pan.
Roast for 30 minutes to develop a golden crust.
Then reduce heat to 160°C (325°F).
Continue roasting for about:
- 15–18 minutes per pound (for medium-rare)
🌡️ STEP 4: CHECK INTERNAL TEMPERATURE
Use a thermometer:
- Rare: 50°C (120°F)
- Medium-rare: 55–57°C (130–135°F)
- Medium: 60–63°C (140–145°F)
👉 Pull roast out 3–5°C before target (it continues cooking while resting)
🛑 STEP 5: REST THE MEAT
Let the roast rest for 20–30 minutes covered loosely with foil.
❌ Don’t skip this step—it keeps juices inside the meat.
🍖 STEP 6: MAKE THE AU JUS
Place roasting pan on stove over medium heat.
Add beef stock and scrape browned bits from pan (this is flavor gold).
Stir in Worcestershire sauce, garlic powder, salt, and pepper.
Simmer for 5–7 minutes until slightly reduced.
Strain if desired for smooth sauce.
🔪 STEP 7: CARVE LIKE A PRO
Slice between bones for classic “King-Cut” portions.
Cut against the grain for tenderness.
