Kim's Prime Rib

Step 1
Preheat the oven to 450 degrees F (230 degrees C).

Step 2
In a medium bowl, combine soy sauce, Worcestershire sauce, garlic powder, onion salt, browning sauce, and water. Place roast in a roasting pan, ribs side down, and poke deep holes in roast with a knife. Pour marinade over roast. Using a baster, squirt marinade into the holes you created with a knife and over entire roast a few times.

Step 3
Bake for about 1 hour. (Note: Bake for 40 to 45 minutes for a smaller roast so that it does not dry out.)

Step 4
Remove roast from the oven and reduce the temperature in the oven to 200 degrees F (95 degrees C).

Step 5
When the oven has reached 200 degrees F (95 degrees C), return roast to the oven and continue cooking for 18 to 22 minutes per pound, or until internal temperature reaches 145 degrees F (65 degrees C).
