How to Make Prime Rib in an Electric Roaster

Delicious and Easy Prime Rib in an Electric Roaster


  • 6 - 8 lbs Prime Rib Roast
  • Sea Salt or Kosher Salt to taste
  • 2 tsp or more of Black Pepper
  • 1 to 2 tsp Dried Rosemary
  • 1 to 2 tsp Dried Thyme
  • 5 - 6 cloves Minced Garlic I used jar garlic because I didn't have my own available


  1. Take the roasting rake out of the roaster and set aside.
  2. Plug your electric roaster in, lid on and pre-heat to 325 degrees F.
  3. A lot of cooks will tell you to leave the roast on the counter for up to 2 hours to allow it to come to room temperature. I don't do that but it is up to you.
  4. Open your roast and place it on the roasting rack so you can just lift it into the roaster once it is prepared.
  5. We aren't going to be super precise with the seasonings - trust me, it is going to be ok! However you are going to get your hands all over uncooked meat so please take safety precautions to keep from doing any cross-contamination.
  6. Liberally salt the roast on all sides.
  7. Now evenly spread out the black pepper, rosemary and thyme over all sides of the roast.
  8. Really press those seasonings into the meat, including the salt.
  9. Next I like to spread the minced garlic on the top only but you can try to spread it around if you want.
  10. Carefully life the rack with the prime rib into the pre-heated electric roaster. You do not need to add any liquid to the pan.
  11. Put the meat thermometer dead center in the meat; and make sure it is on and set to your desired doneness.
  12. 130ºF - Rare
  13. 135ºF - Medium Rare
  14. 140ºF - Medium
  15. 150ºF - Well Done
  16. Replace the lid. Leave the roaster at 325 degrees F and DO NOT OPEN THE LID!
  17. Once done remove the prime rib from the electric roaster and allow it to rest for 15 - 20 mins.
