To prepare, dry the steak with paper towels. It should be completely dry in order to assist with browning. Season it and sear on a pre-heated, hot skillet with a little bit of olive oil for 2-4 minutes per side, until brown. Use tongs to occasionally press the steak against the pan. For a medium-rare skirt steak, cook until the interior temperature reached 130 degrees F. Once cooked to the desired temperature, remove the steak from the pan and move it to a cutting board, loosely cover it with foil, and allow it to rest for 10 minutes. To cut, slice 1/4 inch slices at a 45-degree angle, against the grain.
