Do you increase cooking time for 2 tenderloin beef roasts?

Cooking time will need to be increased if you are cooking two tenderloin beef roasts.

Tenderloin roasts are typically cooked at a lower temperature (around 300 degrees Fahrenheit) for a longer period of time (around 20-25 minutes per pound) to ensure they remain tender and juicy.

Because you are cooking two roasts, they will take up more space in the oven and the heat will not circulate as efficiently, so you will need to increase the cooking time by about 10-15 minutes per roast to ensure they cook evenly.

To test the doneness of your tenderloin roast, insert a meat thermometer into the thickest part of the meat. It is done when the internal temperature reaches 135 degrees Fahrenheit for medium-rare, 145 degrees Fahrenheit for medium, or 155 degrees Fahrenheit for medium-well.
