How to Julienne Vegetables

Julienne is a shape rather than a technique: a long strip with square sides, roughly the proportions of a matchstick. Because it is a shape, there are several ways to get there, and the right one depends entirely on the vegetable. A knife owns anything you can cut into a flat plank. A julienne peeler owns anything long, firm and round. A mandoline blade owns volume. And a food processor disc owns the case where you need a great deal of it and do not care whether the strips are perfect.

The knife method: plank, stack, strip

1. Square it off. Trim the vegetable into a rectangular block by slicing a thin piece off each rounded side. A carrot becomes a rough rectangle; a zucchini becomes a block with the seedy core cut away. This is the step people skip and it is the reason their julienne comes out as wedges.
2. Cut planks. Slice the block lengthwise into flat slabs about as thick as you want the strips to be square. Thin planks give fine julienne; thicker ones give batons.
3. Stack and strip. Lay two or three planks on top of each other, hold them flat with the fingertips of your guiding hand curled back, and cut down through the stack at the same spacing. That is julienne.

The whole technique is about making flat surfaces before you make cuts. A round vegetable rolls, and a rolling vegetable is both the reason your strips are uneven and the reason you might cut yourself. Everything in step one exists to stop that.

If you want dice instead, you are already most of the way there: line up the julienne strips and cut across them. Every small dice in every recipe you have ever read is a julienne that got one extra cut.

The tools, and what each one is genuinely for

A julienne peeler

This is the cheapest and the most underrated of the three. It is a Y-peeler with a toothed blade: you draw it down a carrot or a zucchini and it produces strips in one stroke, with no board, no planking and no stacking. For carrot salad, for a garnish, for zucchini strips in a stir-fry, it is faster than a knife and far faster than setting up a mandoline.

Its limits are real. It only works along the length of something long and firm — carrots, zucchini, cucumber, daikon, firm apples and pears, a peeled beet. It cannot do peppers, onions, cabbage or anything you would need to lay flat. And it stops when the vegetable gets too thin to hold, exactly like an ordinary peeler.

The honest oddity of this category, which our julienne peeler roundup makes its centerpiece: no maker publishes the width of the strip its teeth cut. Not one of the peelers we resolved states it. So you cannot choose one on strip size, and we do not pretend otherwise — we rank them on the things makers do state, starting with whether a blade cover is included.

A mandoline with a julienne blade

This is the volume answer. A julienne insert on a mandoline turns a whole vegetable into strips in a few passes, and the strips are more uniform than anything a hand can produce. For a slaw, for a large batch of pickles, for a dish where the look is the point, it is the right tool.

The OXO Chef’s Mandoline offers julienne and French-fry cuts from its dial without swapping a blade in, which is a genuine safety advantage. The Benriner gives the finest, cleanest julienne of anything in our catalog, using three interchangeable blades — and it demands the attention its own card warns about. If a mandoline would be your first, our beginner mandoline page covers which one to start on and the glove to buy with it.

A food processor with a julienne disc

The hands-off option, and the least precise. A julienne or French-fry disc pushes food through a grid at speed, which gives you a great deal of julienne very quickly with ragged ends and inconsistent lengths. For a slaw that will be dressed and for anything that gets cooked, that is completely fine. For a garnish, it is not. Our guide to blades and discs explains which machines ship a julienne disc and which sell it separately.

Which vegetable, which tool

Getting it even

Evenness matters for cooking, not for looks: strips of different thicknesses cook at different rates, and in a stir-fry that means some pieces are raw and some are collapsing. Three habits fix nearly all of it.

Make a flat face first, every time. Whether you are using a knife, a peeler or a mandoline, a vegetable that cannot roll cuts evenly.

Cut with the length, not across it. Julienne runs along the fiber of the vegetable. Cut across the grain and the strips break up, which is why carrots juliennes lengthwise hold together and ones cut across do not.

Stop before the last bit. With a knife, the final plank has nothing to hold onto; with a peeler or a mandoline, the last inch is where fingers meet blades. Keep the ends for stock. Our mandoline safety guide makes the same point rather more forcefully, because on a mandoline it is the one rule that matters.

What to do with julienne once you have it

Raw, dressed: carrot salad with lemon and oil, cucumber and daikon for a banh mi, apple and celeriac in a remoulade. This is where evenness shows most and where a peeler or a mandoline earns its place.

Stir-fried: peppers, carrots, zucchini and ginger, all julienned so they cook in the same couple of minutes. The whole reason the cut exists is that thin strips cook fast and evenly.

Fried: julienned potato is the shape of a shoestring fry, and a slightly thicker batonnet is the shape of a standard one. If fries are actually what you are after, a dedicated french fry cutter pushes a whole potato through a grid in one stroke and gives far more consistent results than any of the methods here.
