Mastering the Essential Knife Cuts
Consistent vegetable cuts ensure even cooking and improve the texture of your finished dish. By standardizing the shape and size of your onions, carrots, and celery, you prevent smaller pieces from turning to mush while larger chunks remain raw.
Consistency is your primary goal.
Before you begin, ensure your knife is sharp. A dull blade slips, while a sharp edge bites into the vegetable, giving you control over the shape.

Keep your fingers tucked
Curl your fingertips inward toward your palm, resting your knuckles against the side of the knife blade. This creates a physical stop that keeps your fingertips away from the edge.
The method.
The Batonnet
Square off your carrot by cutting thin slices off the sides. Cut the rectangle into 1/4-inch thick planks, then stack the planks and cut them into 1/4-inch matchsticks, usually 2 inches long.
The Julienne
Follow the same process as the batonnet, but cut your planks into 1/8-inch thick matchsticks. These are thin and cook almost instantly when tossed into a stir-fry.
Small Dice
Take your batonnet sticks and line them up horizontally on the board. Cut across them at 1/4-inch intervals to produce uniform cubes.
Brunoise
Start with a julienne. Gather the matchsticks into a bundle and cut across them at 1/8-inch intervals. This creates tiny, precise cubes used for garnishes or aromatics.
The Dice (Onion)
Keep the root end intact to hold the onion together. Make vertical slices toward the root without cutting through it, then make two horizontal cuts into the onion face, and finally slice downward across the top.
When it doesn't go to plan.
Use a bench scraper to gather your cuts; avoid dragging the sharp edge of your knife across the board, which dulls it quickly.
If your vegetables are rolling on the board, slice a small strip off one side to create a flat, stable base.
When dicing, let the weight of the knife do the work; you should be guiding the blade down rather than forcing it through the vegetable.
The ones that keep coming up.
Why does size matter for cooking?
Surface area dictates how quickly heat penetrates the vegetable. Smaller, uniform cuts soften rapidly, while larger, uneven cuts create a disjointed mouthfeel where some parts are mushy and others are crunchy.
How do I know when my knife is sharp enough?
The knife should slice through a ripe tomato under its own weight without you needing to press down.
