How to Dice Potatoes ( Step-by-Step Guide )

Let me tell you from experience—learning how to dice potatoes properly makes a huge difference in cooking. Potatoes that are evenly cut and cooked at the same speed look attractive when served.

I remember the first time I ever tried to make breakfast hash. The way the recipe was written made it appear easy, but I got stuck once I got to dicing the potatoes. 
What was the process of ‘dicing’ them? Was that the same as cutting them into cubes? 

Also, what kind of kitchen knife should I be using for dicing?

How to Dice Potatoes: Step-by-Step Process

So, let me walk you through exactly how to dice potatoes. This is the method I use every single time:

1. Firstly, wash and peel the potatoes: if you want a neat and gentle texture, peel them, especially when preparing breakfast dishes.
2. Second, cut the potato in half lengthwise. After washing the potato, slice it lengthwise; this will provide a safer and more straightforward way to go forward.
3. Thirdly, slice each half into even planks. The width of your cubes can vary between ¼ and ½ inch per slice.
4. Then, stack and slice into matchsticks: Put two or three slices on top of each other and then slice them into sticks.
5. Lastly, turn and dice: Afterward, spin the sticks and cut them at right angles to get uniform cubes.

That’s how I learned how to cut potatoes into cubes, and I’ve never looked back. 

Slicing Your Potatoes into Half-inch Pieces

Want half-inch pieces? Just aim for each side of the cube to be about ½ inch when you cut. This technique also works if you're trying to figure out how to dice potatoes into 1/2 inch pieces specifically.

How to Dice Sweet Potatoes

Now, if you’re wondering how to dice sweet potatoes, the method is almost identical but with a few minor adjustments. Since sweet potatoes are more solid, I use a sharp and heavy kitchen knife

So, here's how to dice sweet potatoes

1. Peel and trim the ends.
2. Slice into thick rounds – I aim for about ½ inch thick.
3. Stack and cut into sticks.
4. Dice the sticks into cubes.

The procedure isn’t changed, although you might have to put in a little more effort. My advice is to work with a sharp and heavy knife while chopping sweet potatoes. I personally prefer Chef knives (some recommendations below) as they are generally best for dicing. But Nakiri knives and cleaver knives are also a good shout.

Dicing Potatoes for Soup

And now, let's address dicing potatoes for soup. When dicing potatoes for soup, cut into small cubes, roughly ¼ inch. That way, they easily become tender as you cook,  and mix well with the broth. 

Even so, the main technique does not change. It’s simpler to slice them thinly and reduce the size of your cuts.

Is Dicing the Same as Cutting Potatoes into Cubes?

Dicing is just the fancy word for cutting into cubes. To dice potatoes means to cut them into small cubes.  The purpose is to have each piece be small and cook evenly. Potatoes generally have to be uniform if you want them to cook evenly.

Usually, people dice potatoes so they can cook them faster and add texture to soups, breakfast skillet meals, or casseroles.

So, how you dice potatoes will result in them being crispy or tender when you cook them?
