      About This Article

      Article Summary X

      To keep shrimp from curling up when they cook, cut a few small, horizontal slits on the underside of the shrimp. Press the shrimp flat on your cutting board to straighten it out even more before you cook it. Cutting shrimp butterfly style can also help prevent them from curling up. To do this, slice the shrimp almost in half lengthwise from head to tail, then spread it out and press it flat. When you cook the shrimp, watch it carefully to prevent overcooking it, which can cause it to shrink and get rubbery. The shrimp is done when it’s opaque, pink, and just starting to curl.
