Cut off the fennel fronds using a large chef’s knife. (You can use the wispy portions as a garnish if you’d like.)
Cut off the root end of the fennel.
Remove any tough outer layers of the fennel and discard them.
Slice down the center of the fennel bulb.
To slice the fennel, place the fennel on the cut side and cut thin half-moon slices parallel to the root end using a circular motion. OR…
To dice the fennel, cut slices parallel to the root end, leaving room at the end so the slices stay attached. (Make the slices wider for diced and narrower for minced.) Then rotate the fennel and cut slices in the other direction, following the curve of the fennel. When you’ve cut halfway through, flip the fennel down onto the flat cut side and continue slicing. When you reach the end that didn’t have the slices, give it a few more chops. See the video for this part!
