Temperatures for Beef Tenderloin:

The internal temperature will continue to rise as the roast rests after removing it from the grill. Do not  overcook the tenderloin, the results will be dry and flavorless.

Tips for Cooking Beef Tenderloin:

Use a digital thermometer to check the internal temperature of the meat. This is essential rather you are grilling or oven roasting. 

Do not over cook a beef tenderloin roast. It is an expensive cut of meat and will be much more juicy and delicious if it is cooked no more than medium. 

Allow the roast to rest for at least 15 minutes before slicing to allow the juices to distribute through out the meat. 

How to Store and Reheat:

Store tightly wrapped in several layers of plastic wrap in the refrigerator up to 4 days. 

Reheat in a skillet with butter or olive oil over medium heat, turning once to heat through on both sides, about 3- 5 minutes.

We also like to slice a whole tenderloin into filet mignon on the grill for a tender and delicious steak dinner.

      1. Hi Elly,
        It can be done on a gas grill. The cooking time is generally about 15 minutes per pound. Use a digital thermometer for the best results.
