The Prep Cuts Every Home Cook Should Know
A practical guide to the 8 fundamental knife cuts that speed up weeknight cooking. Covers dice, julienne, chiffonade, brunoise, and more, with the specific board and blade setup that makes each one easier.
Eight cuts handle 90% of home cooking. Master the dice, the julienne, the mince, the chiffonade, the brunoise, the bias cut, the rough chop, and the batonnet, and you can prep any recipe faster than the time it takes to preheat your oven.
Most home cooks know two cuts: the rough chop and the "I hope this is small enough." The gap between those and proper technique is not talent. It is knowing what cut the recipe actually calls for, why it matters for cooking time and texture, and having a board and blade setup that makes each one repeatable.
What are the 8 essential prep cuts?
These are the cuts professional kitchens drill into every new cook on day one.
| Cut | Dimensions | Best For | Knife Motion |
|---|---|---|---|
| Rough chop | Irregular, 1-2" pieces | Stocks, soups, roasting | Push cut, fast |
| Dice (medium) | 1/2" cubes | Salsas, stir-fries, sauces | Push cut, measured |
| Small dice | 1/4" cubes | Mirepoix, stuffings, grain salads | Push cut, precise |
| Julienne | 1/8" x 1/8" x 2-3" sticks | Stir-fry, salads, garnish | Push cut from planks |
| Brunoise | 1/8" cubes | Sauces, vinaigrettes, fine garnish | Cross-cut julienne |
| Chiffonade | Thin ribbons | Basil, mint, leafy herbs | Roll and slice |
| Bias cut | 1/4" diagonal slices | Scallions, celery, carrots | Angled push cut |
| Batonnet | 1/4" x 1/4" x 2-3" sticks | French fries, crudites | Push cut from planks |
The dice is the one you will use five nights a week. The julienne is the one that impresses people. The chiffonade is the one that takes 10 seconds and makes a plate look finished. Learn the dice first and branch out from there.
Why does cut size actually matter?
Because cooking is heat transfer, and heat transfer depends on surface area.
A 1-inch potato cube takes roughly 25 minutes to cook through in a 400-degree oven. A 1/2-inch cube of the same potato takes 12 to 15 minutes. A 1/4-inch dice takes 8 minutes. If you mix sizes in the same pan (which most home cooks do by default), some pieces burn while others stay raw in the center.
Consistent cuts are not about presentation. They are about everything in the pan reaching the same doneness at the same time. This is the single biggest difference between a home-cooked dish that tastes composed and one that tastes like a collection of ingredients that happened to be in the same pot.
A stable, flat cutting board is what makes consistent cuts possible. If the board wobbles, your knife angle shifts with every stroke. The cuts come out uneven not because your hand is unsteady but because the surface under the food is not level.
How do you dice an onion properly?
Peel the onion and cut it in half through the root. Lay one half flat (cut side down) on the board. Make 3 to 4 horizontal cuts toward the root, stopping about 1/2 inch from it. Then make vertical cuts from the top, parallel to the root lines, again stopping short. Finally, cross-cut from the opposite end. The root holds everything together while you work.
This is the technique every cooking show demonstrates but rarely explains: the root is your clamp. If you cut the root off first, the onion falls apart and you spend twice as long chasing pieces around the board.
The board requirement here is non-negotiable: it must be flat and it must not slide. The horizontal cuts put lateral force on the onion, and if the board shifts, the onion shifts, and your parallel cuts lose their spacing. A heavy board with rubber feet eliminates the problem.
What is the difference between julienne and batonnet?
Size. That is it. Both are rectangular sticks cut from planks.
A batonnet is 1/4 inch by 1/4 inch by 2 to 3 inches. It is the cut you use for French fries, crudites, and any application where you want uniform sticks that hold their shape during cooking.
A julienne is half that: 1/8 inch by 1/8 inch by 2 to 3 inches. It is the cut for stir-fry vegetables, salad garnishes, and anything that needs to cook in under 2 minutes.
The method is the same for both. Square off the vegetable (cut a thin slice from each side to create flat faces). Cut lengthwise into planks at your target thickness. Stack 2 to 3 planks and cut lengthwise again into sticks.
The board surface matters here because you are stacking thin planks and running a blade through them. An end-grain surface grips the food slightly, preventing the stack from sliding. A slick plastic board lets the planks shift mid-cut, and your julienne turns into an inconsistent mess.
How do you chiffonade herbs without bruising them?
Stack 6 to 8 leaves (basil, mint, sage). Roll them tightly into a cigar shape. Slice across the roll with a sharp knife using a single clean push cut, not a sawing motion.
The key word is sharp. A dull knife crushes the herb cell walls instead of slicing them, releasing enzymes that turn the cut edges black within minutes. This is why restaurant basil stays green and home-cooked basil turns dark: it is not the variety, it is the blade.
The board surface contributes too. A hard surface like glass or ceramic causes the blade to bounce slightly on each stroke, tearing the delicate leaves instead of cutting them. An end-grain wood surface absorbs the blade's energy cleanly, producing a single smooth cut through the roll.
What is a brunoise and when do you use it?
A brunoise is a 1/8-inch cube. You make it by cross-cutting a julienne. It is the finest standard dice in classical technique.
Use it for vinaigrettes (finely diced shallot), compound butters (minced herbs and aromatics), and any sauce where you want the flavor of the aromatic without visible chunks. A brunoise-cut carrot in a consomme dissolves into the broth. A rough-chopped carrot does not.
This is the cut that separates careful prep from fast prep. You cannot brunoise on a board that moves. The cuts are too small and too precise. Your guiding hand is doing fine motor work, curled into a claw grip with knuckles forward, and any shift in the board translates directly into uneven cubes.
A 17-inch end-grain maple board gives you the surface area and stability for 20 minutes of brunoise work without repositioning.
Which knife should you use for each cut?
Chef's knife (8 to 10 inches): The default for everything. Dice, julienne, batonnet, rough chop, mince. If you own one knife, this is it.
Paring knife (3 to 4 inches): Detail work. Peeling, trimming, tournet (turned vegetables, which you will probably never need at home). Too small for board work.
Nakiri (6 to 7 inches): The flat-profiled Japanese vegetable knife. Excellent for push cuts and tall vegetables like cabbage. Cannot rock, so it does not mince well.
Santoku (5 to 7 inches): The Japanese all-purpose knife. Shorter than a chef's knife with a flatter profile. Good for people with smaller hands who find an 8-inch chef's knife unwieldy.
Every one of these knives performs better on an end-grain hardwood surface than on plastic, bamboo, or glass. The blade-friendly surface preserves the edge between sharpenings, which means your knife stays sharp enough for precision work longer.
How do you practice knife cuts without wasting food?
Buy a 5-pound bag of potatoes and a bundle of carrots. That is your practice kit for under $4.
Potatoes are the ideal practice vegetable: they hold their shape, they have enough resistance to feel like real prep, and they are cheap enough that imperfect cuts go into soup or hash without guilt. Cut a potato into planks, then into batonnets, then dice the batonnets. Save everything. Potato soup does not care about uniformity.
Carrots are harder (literally and technically). Their cylindrical shape rolls on the board, which forces you to create a flat face first. That single preliminary cut, slicing a thin strip off one side to create a stable base, is the most important habit in knife work. It applies to every round vegetable and fruit: zucchini, cucumbers, eggplant, apples.
Practice 10 minutes before you start cooking dinner. In two weeks your cuts will be visibly more consistent. In a month they will be automatic.
Does the cutting board height affect your cut quality?
Yes. The ideal cutting height puts your elbows at roughly 90 degrees when your hands rest on the board surface. Too low and you hunch, losing control of the blade's arc. Too high and you cannot apply consistent downward pressure.
Standard kitchen counters are 36 inches. A 1.75-inch-thick cutting board brings the work surface to about 37.75 inches, which works for people between 5'6" and 6'2". If you find yourself leaning over the board or reaching up to it, the height is wrong and no amount of technique will fix the inconsistent cuts that result.

Ready to put these cuts to work?
Consistent knife cuts are not a professional flex. They are the reason food cooks evenly, sauces come together, and plates look intentional. The knife does the cutting. The board makes it possible. Start with a surface that stays flat, stays put, and works with your blade, and the technique follows. Explore boards built for real prep work at Bevel & Bond.
