Ingredients
-
1 (4 lb) prime rib roast, bone-in preferred
-
3–4 tbsp King of Meat seasoning (use closer to 3 tbsp for boneless or lighter seasoning, and closer to 4 tbsp for large bone-in roasts or a bolder crust)
-
4 tbsp butter, softened
-
¼ cup beef tallow, divided
-
¼ cup fresh herbs, chopped (rosemary and thyme recommended)
-
1 lb baby potato medley, halved
-
Salt and pepper, to taste
Directions
Remove the prime rib from the refrigerator about 2 hours before cooking.
Pat the roast dry thoroughly with paper towels.
Season the roast evenly with King of Meat seasoning on all sides.
Preheat oven to 425°F.
In a small bowl, combine softened butter, 2 tablespoons beef tallow, and chopped herbs.
Spread the herb butter mixture evenly over the roast.
Toss potatoes with remaining beef tallow and lightly season with salt and pepper.
Spread potatoes around the outer edge of a roasting pan in a single layer.
Place the roast on a rack in the center of the roasting pan above the potatoes.
Roast at 425°F for 20 minutes to develop the crust.
Reduce oven temperature to 275°F and continue roasting for approximately 15–20 minutes per pound.
Baste the roast and potatoes every 30 minutes using the rendered juices from the pan.
Begin checking the internal temperature during the final hour of cooking.
Remove the roast when the internal temperature reaches 125°F for medium-rare.
Tent loosely with foil and rest for 20 minutes before slicing.
Ensure potatoes are fork tender and golden before serving.
Recipe Note
Patting the roast dry helps develop a deeper crust during roasting.
Using a rack allows the potatoes to roast instead of steam underneath the roast.
Bone-in prime rib provides additional flavor and helps retain moisture during cooking.
A thermometer is the most reliable way to avoid overcooking prime rib.
Resting the roast is essential for juicy slices and proper carryover cooking.
