First, your prime rib needs to be at room temperature!

Place your prime rib in an empty turkey fryer & fill with water to where it's covered entirely with an inch above the roast. Mark the area with a sharpie so you know where to fill the oil up to. Very important! Drain the water from the turkey fryer, remove the roast, dry the fryer pot, & fill to the line with peanut oil.

Heat the oil to 350 degrees.

Combine the garlic powder & melted butter. Using a meat injector (you can buy this in the cooking supply aisle or on Amazon), inject the prime rib from all different angles with the garlic butter.

Rub salt, pepper, & garlic powder all over the roast to taste - or you can use your favorite steak seasoning.  Using a sharp knife, make a hole right down the middle of your prime rib roast so that you can insert the turkey fryer rack easily. Insert your turkey fryer rack & slowly lower into the hot oil. Fry, at 350, for 4 minutes per pound. Wrap in foil as soon as it's removed & let sit for 45 minutes before slicing.
