Step 1: Wanting to Easily Dice an Onion ?

Peel onion ..

Find plastic lid that the onion will fit into .. (This onion is already sliced as i started the photo shoot after i was midway through the dicing process )

Step 2: Place Onion in Plastic Lid.

Step 3: As You Slice Down Through the Onion the Lid Stops the Knife From Going All the Way Through.

Slice a checker board pattern into the onion. ( Cut into the onion starting at the right edge . Press the blade into the onion until the blade is impeded by the plastic lid .. Remove the blade from the onion and repeat the slicing process in parallel cuts across the rest of the onion to the left. Rotate the onion 90 degrees and repeat the cutting process perpendicular to the first cuts. ) ( I used a radial cut method in the photos. I describe the checker board cut pattern because I like it better.)

Step 4: Now to the Dicing .

Turn the onion onto its side..

Step 5: Product

Slice across the onion and the previous cuts creating nicely diced onions.

    I use a similar tactic, but instead of cutting it like a pie, I cut it like a grid. That way the outer pieces are the same size as the inner pieces. Also, I only cut deep enough to get the amount of onions I am going to use. The rest I try to leave in tact for future use.

    That's nice, but when you cut it all the way to the lid a portion of onion stays un-sliced. And it is a pain to cut. Any advise on how to make it easier?

    I'd just use that technique to dice the majority of the onion for hot dogs, chili or beans. The rest could be put up for another use.

    Awesome idea! I cut onions all the time, if you have any tips for cutting bell peppers please share!

    Thank you- and all my fingers thank you also !

    I got my inspiration from Grant Thompsons ( The King of Random) Apple Swan video. He used butter knives as a spacer with an apple to make the slices needed for the decorative swan.

    Stabilizing the onion is a great safety feature, too, especially for those of us without expert chef knife skills and experience.
