Things You'll Need:
-
Step 1
Wet both hands with cold water, and then press ½ cup rock salt and 3 tbsp. minced garlic into the entire surface of the prime rib roast. Preheat a gas grill to high heat and cook the prime rib roast for 4 minutes on each side to sear.
-
Step 2
Move the prime rib roast to the upper grill rack and place a drip pan beneath it on the lower rack. Cover the surface of the meat with chopped garlic cloves for flavor.
-
Step 3
Insert a meat thermometer into the roast and allow it to cook for 25 minutes per lb. Remove the roast from the grill when the meat thermometer reads 130 degrees F for rare or 150 degrees F for medium well. Move the prime rib roast directly to a cutting board and cover with aluminum foil. The internal temperature of the meat will increase an additional 10 degrees while under the foil.
-
Step 4
Remove the aluminum foil from the meat. Carve with a sharp knife. Serve immediately for ideal flavor and texture. Serve with barbecue sauce or steak sauce, if desired.
