Five cuts cover almost everything a home cook needs: the slice, the dice, the fine chop (or mince), the julienne and the chiffonade. Learn them with a sharp knife, a steady board and the claw grip, and prep that used to take twenty minutes starts to take ten. You do not need chef's speed or a drawer of specialist knives. You need one good cook's knife, a sensible technique and a little practice. Below you will find how to set up safely, step-by-step instructions for each cut, what each one is for, and the habits that slow most people down.
Before you cut: set up safely
Good knife work starts before the knife touches food. A few basics make cutting faster and much safer.
- Use a sharp knife. A blunt blade needs more pressure and is more likely to slip off a tomato skin or an onion and into your finger. Hone regularly and have it sharpened when it stops biting cleanly.
- Keep the board stable. Put a damp tea towel or a sheet of damp kitchen paper under your chopping board so it cannot slide around.
- Make a flat side. Round vegetables roll. Cut a thin slice off one side of a carrot, potato or onion and lay it on that flat face before you go any further.
- Use the claw grip. Curl the fingertips of your guiding hand under, so your knuckles face the blade and your fingertips are tucked away. The flat of the knife rests lightly against your knuckles, which act as a guide as you move back.
- Give yourself room. A cluttered board is where accidents happen. Scrape finished food into a bowl with the spine of the knife, not the edge, which also keeps the blade sharp.
Hold the knife with a pinch grip: thumb and index finger gripping the blade just in front of the handle, the other fingers wrapped around the handle. It feels odd at first but gives far more control than holding the handle alone.
The five cuts
1. The slice
The foundation of everything else. Keep the tip of the knife on the board and move the blade forward and down in a smooth rocking motion, rather than chopping straight down. Your claw hand moves back steadily by the same amount each time, which is what keeps slices even.
Use it for: courgettes, aubergines and tomatoes for gratins and bakes, cucumber for salads, mushrooms for a stir-fry.
2. The dice
Dicing turns a vegetable into even cubes so everything cooks at the same rate. Square off the vegetable, cut it into planks of the thickness you want, stack the planks and cut them into sticks, then line the sticks up and cut across into cubes.
For an onion, halve it through the root, peel, and lay it cut side down. Make vertical cuts towards the root without cutting through it, so the root holds the layers together. Then slice across and the dice falls away.
Use it for: onions, carrots and celery for soups and sauces, peppers for salsas, potatoes for hash.
3. The fine chop (or mince)
For garlic, ginger, chilli and herbs, where you want small pieces that melt into a dish. Roughly chop first, then place your guiding hand flat on the spine of the knife, near the tip, and rock the blade back and forth across the pile. Gather it together with the knife and repeat until it is as fine as you want.
Use it for: garlic and ginger for curries and stir-fries, parsley and mint for tabbouleh, chilli for dressings.
4. The julienne
Thin matchsticks, usually a few millimetres wide. Cut the vegetable into lengths of about 5 cm, slice them thinly, stack the slices and cut them lengthways into matchsticks. For slightly thicker batons, simply cut wider.
Use it for: carrots and peppers for stir-fries and spring rolls, cucumber and radish for salads and bowls, celeriac for slaw.
5. The chiffonade
A neat way to cut leafy herbs and greens into fine ribbons without bruising them. Stack the leaves, roll them tightly like a cigar, and slice across the roll with a sharp knife. Unroll and you have ribbons.
Use it for: basil for pasta and tomato salads, mint for yogurt sauces, spinach or kale for soups and stews.
Which cut for which job
| Cut | Rough size | Best for |
|---|---|---|
| Slice | Even rounds or half-moons | Bakes, gratins, salads, stir-fries |
| Dice | Small to large cubes | Soups, sauces, salsas, stews |
| Fine chop | As small as possible | Garlic, ginger, chilli, herbs |
| Julienne | Thin matchsticks | Stir-fries, slaws, rolls, bowls |
| Chiffonade | Fine ribbons | Basil, mint, leafy greens |
Putting it into practice
The best way to learn is to cook dishes that need the cuts. In The Healthy Kitchen, a Chickpea, Cucumber & Herb Salad is a good dicing and fine-chopping workout, an Indian Kachumber-Chana Chaat Salad rewards a small, even dice, and a Crispy Tofu & Broccoli Stir-Fry is a chance to practise slicing and julienne. The Provençal Ratatouille & White Bean Stew puts all of that to work in one pot.
Knife skills also make batch cooking far less of a chore. If you prep vegetables for the week in one session, as in our Sunday meal prep plan, even cuts mean everything cooks evenly later. Save the onion ends, carrot peelings and celery tops for homemade stock.
Common mistakes that slow you down
- Using a small knife for big jobs. A paring knife is for peeling and trimming. For most chopping, a cook's knife of around 18 to 20 cm is easier and safer.
- Chopping straight down. Pressing down crushes food and tires your wrist. Let the blade move forward as it cuts.
- Lifting the knife too high. Keeping the tip close to the board gives you more control and steadier slices.
- Uneven pieces. Mixed sizes cook unevenly, so some pieces burn while others stay raw. Take a second to square things off.
- Trying to catch a falling knife. Step back and let it fall.
- Leaving knives in the washing-up bowl. A hidden blade under soapy water is a classic cause of cuts. Wash and dry knives separately and put them away straight after.
Questions people ask
What is the most important knife for a home cook?
A good cook's knife (sometimes called a chef's knife) will handle the vast majority of jobs. Add a small paring knife for fiddly tasks and a serrated knife for bread, and most kitchens need little else.
How often should I sharpen my knife?
It depends on how much you cook and what you cut on. Many cooks hone their knife with a steel every time they use it and have it properly sharpened a few times a year. If it squashes a tomato instead of slicing it, it is time.
Which chopping board is best?
Wood and good-quality plastic boards are both kinder to knife edges than glass, marble or ceramic. Choose one large enough to work on comfortably, and consider a separate board for raw meat or fish if you cook them.
How do I stop crying when I chop onions?
A sharp knife helps, as it damages fewer cells and releases less of the irritating compound. Chilling the onion briefly and working quickly also helps. For more ideas to practise on, try the salad recipes in the finder.
