Best Prime Rib Roast Recipe Ever

Description

This prime rib roast recipe features a juicy, tender interior and a crisp garlic-herb crust, slow-roasted to perfection and reverse-seared for a golden finish. Ideal for holidays or special occasions, it’s a restaurant-quality dish you can easily make at home.

Ingredients

Scale

1 standing rib roast (4–6 pounds, bone-in preferred)
2 tablespoons olive oil or softened butter
2 teaspoons kosher salt
1½ teaspoons freshly ground black pepper
1 tablespoon fresh rosemary, finely chopped
1 tablespoon fresh thyme, finely chopped
4 cloves garlic, minced

Instructions

Take the rib roast out of the refrigerator and let it sit at room temperature for 1 hour.
Preheat the oven to 250°F (120°C). Pat the roast dry with paper towels.
In a bowl, mix olive oil or butter, salt, pepper, rosemary, thyme, and garlic. Rub this mixture all over the roast.
Place the roast bone-side down on a rack in a roasting pan. Insert a meat thermometer into the thickest part, avoiding bone.
Roast uncovered until internal temperature reaches 118–120°F for rare or 123–125°F for medium-rare (about 2½ to 3½ hours).
Remove from oven, tent with foil, and let it rest for 30 minutes.
Increase oven temperature to 500°F (260°C). Return roast to oven for 8–10 minutes to create a crust.
Let rest for another 10 minutes before slicing and serving.

Notes

Always use a meat thermometer for best results.
Letting the meat rest twice ensures maximum juiciness.
Reverse-searing adds flavor and texture without overcooking the interior.
You can season the roast up to 24 hours in advance for deeper flavor.
Use fresh herbs for optimal aroma and taste.
