To make this EASY Prime Rib, you will need the following ingredients:
1 5 lb standing beef rib roast
2 tsp salt
1 tsp black pepper
1tsp garlic powder
Allow meat to stand at room temperature for at least 1 hour.
In a small bowl, combine salt,
and garlic powder.
Rub the roast with the seasoning.
Place roast in a pre-heated 375 degree oven for 1 hour. Turn the oven off and leave the roast inside. DO NOT OPEN THE DOOR. Leave the roast in the off oven for 3 hours. This is where all the slow roasting, low temperature magic happens! 30 minutes before it is time to remove the roast, turn the oven back on to 375 to re heat the roast. Remove from the oven at the three hour mark. Let sit 10 minutes before slicing.
