Briefing

If the meat feels floppy or hard to control, chilling it briefly before slicing helps more than forcing the knife through a warm, uneven piece.

Key takeaways

01Thin, even bistec slices cook faster, brown more evenly, and make it much easier to build tacos that are tender instead of chewy.
02Use a sharp slicing or chef’s knife.
03Remove the meat as soon as it is done to avoid drying it out.

Start with a sharp knife and slightly chilled meat

A sharp knife matters more than brute force. If the meat is very soft, place it in the freezer just long enough to firm the surface a bit. That gives you cleaner, thinner cuts.

01Use a sharp slicing or chef’s knife.
02Chill the meat briefly if it is too soft to cut neatly.
03Set the meat on a stable board that will not slide around.

Cut across the grain

Look for the direction of the muscle fibers and slice across them rather than with them. This shortens the fibers and makes the final taco bite easier to chew.

01Pause and check the grain before the first cut.
02Keep the slices consistent instead of making half thick and half paper-thin.
03Trim away odd flaps that will overcook before the thicker parts are ready.

Cook fast once it is sliced

Thin bistec does best with quick, hot cooking. Have the pan or griddle ready before you finish the slicing so the meat does not sit around losing chill and leaking juices everywhere.

01Preheat the pan before the meat is fully sliced.
02Cook in small batches for better browning.
03Remove the meat as soon as it is done to avoid drying it out.
