🧄 Ingredients You’ll Need

• 2 tablespoons olive oil or softened butter
• 6 cloves garlic, minced
• 2 tablespoons fresh rosemary, finely chopped
• 2 tablespoons fresh thyme, finely chopped
• 2 teaspoons kosher salt (adjust to taste)
• 1½ teaspoons black pepper
• 1 teaspoon onion powder
• 1 teaspoon garlic powder
Optional:

🔥 How to Make the Perfect Slow-Roasted Prime Rib
1️⃣ Bring to Room Temperature
Remove the prime rib from the refrigerator at least 1–2 hours before cooking. This helps it cook evenly and stay juicy.
2️⃣ Season Generously
In a small bowl, mix olive oil (or butter), garlic, rosemary, thyme, salt, pepper, onion powder, and garlic powder. Rub this mixture all over the roast, making sure every side is well coated.
3️⃣ Slow Roast to Perfection
Preheat oven to 250°F (120°C).
Place the prime rib on a rack in a roasting pan, fat side up.
Roast until internal temperature reaches:
• 120°F (49°C) for rare
• 125°F (52°C) for medium-rare
• 130°F (54°C) for medium
This usually takes 3 to 4 hours, depending on size.
4️⃣ Rest the Meat
Remove from oven and tent loosely with foil. Let it rest 30 minutes. This allows juices to redistribute, keeping the meat tender and juicy.
5️⃣ Create the Savory Crust
Increase oven temperature to 500°F (260°C).
Return the roast to the oven for 10–15 minutes, until the outside forms a beautifully browned crust.
