Beef tenderloin is widely regarded as the most tender cut of beef. It is a portion of the very popular T-bone or porterhouse, and the upscale filet mignon comes from the tenderloin. The tenderloin is a very lean cut of beef, so preparation needs to be meticulous with a careful eye not to overcook. Beef tenderloin can be cooked in your oven, on the grill, with a smoker or slow cooker. At Lisolo Farms, we recommend a quick sear on the grill before a slow finish in the oven.
