Using Thermometer to Cook a Prime Rib or Roast
Cooking Prime Rib or Roast with KitchenAid Smart Thermometer
How to Cook the Perfect Roast (Prime Rib)
Here are some cooking tips to ensure your roast comes out perfectly.
- Fully insert the Thermometer so there is no metal showing (just the black ceramic top).
- Avoid any large fat pockets or air pockets in the meat. This cut is especially fatty, so you want to be extra careful to be in the thickest part of the roast.
- The temperature sensor is at the tip and middle of the Thermometer Probe, so make sure the center of the Thermometer Probe is not too close to the surface of the meat
For the juiciest meat and most even cooking, let big roasts rest for a full 30 minutes. But aim for at least 20 minutes for any size roast.

Troubleshooting for Prime Rib
If you are having issues getting the right results on your Prime Rib
- Make sure that you use the cooking setup for Beef > Roast. Using another cooking setup, including Manual mode, may yield inaccurate results.
- Prime Rib or Rib Roast is a particularly fatty cut of meat. Make sure that your Thermometer Probe is inserted all the way to the black ceramic end, and that you are not hitting any air or fat pockets in the meat.
Try reconnecting your Smart Thermometer and placing it in another area of the roast. Give the Smart Thermometer a full 5 minutes to reach a more accurate reading.
