Vegetable Knife Skills and Prep

Proper prep is about consistency, not speed. By cutting vegetables into uniform shapes, you ensure they hit the heat at the same time and soften evenly. Start with a flat base, keep your fingers tucked, and let the weight of the knife do the work.

Before you start

Stability is your primary goal.

If a vegetable rolls on the board, it is dangerous. Always trim a small side off to create a flat, stable surface before you begin chopping.

  • Chef's knife
  • Large wooden or plastic cutting board
  • Bench scraper

The key technique

Protect your fingertips

Curl your non-cutting hand into a claw, pressing your fingertips against the vegetable while your knuckles act as a guide for the blade. This keeps your nails away from the edge.

Step by step

The method.

  1. Clear your space

    Wipe your cutting board with a damp paper towel before placing it down; this prevents it from sliding while you work.

  2. Establish the anchor

    For round vegetables like onions or potatoes, slice a thin piece off one side to create a stable base that sits flush against the board.

  3. Consistent sizing

    Aim for uniform pieces. If pieces vary in size, the small ones turn to mush while the large ones stay raw.

  4. Gather and clear

    Use your bench scraper to clear the board periodically, keeping your workspace clean so your knife always has a clear path.

Variations

Other turns to take.

The Baton

Cut vegetables into rectangular sticks roughly 2-3 inches long for roasting or crudité.

The Dice

Cut batons into equal, bite-sized cubes for even cooking in soups or stir-fries.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Sharpen your knife regularly; a dull blade requires more pressure and is more likely to slip.

Tip

Keep your board dry when prepping dry ingredients like onions to prevent them from sliding around.

Tip

Store prepped vegetables in airtight containers with a damp paper towel if you are not cooking them immediately.

Questions

The ones that keep coming up.

How do I stop my eyes from stinging when cutting onions?

Use a very sharp knife to make clean slices rather than crushing the cells, and keep the onion cold by storing it in the refrigerator.
