The Three Cuts That Earn Their Place: Dice, Julienne, Chiffonade

Here's the thing nobody tells you when you're learning to cook at home: knife skills aren't about looking like a TV chef. They're about even cooking. When your onion is half big chunks and half slivers, the slivers burn while the chunks stay raw, and your sofrito tastes like both at once. Uniform cuts cook at the same rate. That's the whole game. The pretty plating is a bonus.
There are a dozen classical cuts and you'll never use most of them at home. So tonight, just three. Master these and you've covered 90% of what crosses your board on a weeknight.
Before anything: a sharp knife and a stable board
A dull knife is the single biggest reason home cooks make ragged, uneven cuts — and it's also how people get hurt, because you push harder and the blade skates. If you only fix one thing this week, get your edge back. A Victorinox Fibrox 8" chef's knife is the workhorse we ran in every prep kitchen I've worked — light, grippy, takes a wicked edge for the money. Keep it sharp on a whetstone; learn one stone and you'll never pay for sharpening again. And work on an end-grain board — it's kinder to the edge and to your wrists over a long prep session.
One more: put a damp towel or piece of kitchen roll under the board. A board that slides is a board that bites.
1. The dice
The dice is your base cut — onions, carrots, potatoes, anything you want cooked evenly in a pan or pot.
The trick is to make your raw material flat and square first. Round things roll, and a rolling vegetable is how knuckles get nicked. Cut a thin slice off one side, lay the vegetable on that flat face, then plank it, batonnet it (cut the planks into matchsticks), and finally cross-cut into cubes. Plank → strip → cube. That sequence is the whole method, scaled to whatever size you need: small dice (~6mm) for a quick sauté, large dice (~2cm) for a roast or stew.
Same size = same finish time. A pan of even dice browns in unison instead of giving you charred bits and crunchy bits in the same bite.
2. The julienne
Julienne is just thin matchsticks — roughly 3mm square. It's the dice without the final cross-cut. You use it when you want vegetables to cook fast, like in a stir-fry, or to stay raw and crisp in a slaw or garnish.
Plank the vegetable thinly, stack two or three planks, then slice down through the stack into fine sticks. Stacking is the time-saver, but only stack what you can keep steady under your guide hand. The thin profile means everything in the wok hits doneness at the same moment — no limp peppers next to half-raw carrot.
3. The chiffonade
This is for leafy herbs and greens — basil, mint, sage, spinach. Bruising is the enemy; a dull blade crushes basil and turns the cut edges black in minutes. Sharp knife, here's where it pays off again.
Stack the leaves, roll them into a tight cigar, then slice across into fine ribbons. Don't saw — let the knife do the work in one clean draw. You get delicate, dry ribbons that scatter over a plate instead of a clumped, oxidised mess.
Where the "less waste" comes in
Uniform cuts mean less stuff thrown out, but the bigger win is using the offcuts. Those onion ends, carrot peels, herb stems and the heel of the celery — they don't go in the bin. They go in a bag in the freezer, and once it's full you've got a free stock. The ragged bits from squaring up your vegetables are perfect for it; the cut doesn't matter when it's going to be strained out.
A bench scraper makes this whole flow faster — sweep the good stuff into your pan with one motion, scrape the trimmings into the stock bag with the next, and keep your board clear so you're never cutting around a pile of debris.
Your homework
Buy three onions. Dice all three, back to back. The first will be slow and uneven, the third will surprise you. Speed is just confidence, and confidence is just reps.
That's the pass. Go cook something.
