  • To cut into slices: Place one half of the onion cut-side down. Make cuts vertically into thin or thick slices. Repeat with the other half.
    The onion is cut into thick slices.
  • To dice an onion: Place one half of the onion cut-side down. Cut vertical slices that are parallel to each other, trying to keep the onion together as you go. Turn the sliced onion 90 degrees and make additional cuts that are perpendicular to the original cuts. Make cuts closer together for a finely diced onion and cuts further apart for a coarsely chopped onion.
