Mastering the Knife: Slicing Aromatics

A knife is only as effective as your grip on the vegetable. When you control the shape, you control the final texture of your base.

Before you start

Stability is the foundation of safety.

Always create a flat surface by cutting your aromatic in half first. A rolling vegetable is a dangerous one.

  • 8-inch chef's knife
  • stable wooden cutting board
  • damp towel
Ingredients

What goes in.

  • 3Yellow onions
  • 1 headGarlic
  • 4Shallots
The key technique

Protect your fingers

Tuck your fingertips inward and use your knuckles as a guide for the blade. The blade should never rise above your knuckles.

Step by step

The method.

  1. Stabilize the onion

    Cut the stem end off but leave the root intact. Slice the onion in half through the root. This keeps the layers from sliding while you work.

  2. Radial slicing

    Place the cut side down. Aim your knife tip toward the root, radiating your cuts outward like the spokes of a wheel. This keeps the strips uniform in length.

  3. Slicing garlic

    Smash the clove with the flat of the blade to loosen the skin. Slice crosswise, keeping the knife tip on the board to create a rocking motion.

  4. Shallot precision

    Because shallots are smaller, use the 'butterfly' method: slice partially through the width without cutting through the root, then slice down the length.

Variations

Other turns to take.

The Dice

After radial slicing an onion, make two horizontal cuts into the onion body toward the root, then slice across to create uniform cubes.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Use a damp paper towel underneath your cutting board to prevent it from sliding.

Tip

Keep your knife sharp; a dull blade crushes cell walls rather than slicing them, which releases too much moisture and makes onions weep.

Tip

If you need transparently thin slices, use a mandoline, but always use the guard.

Questions

The ones that keep coming up.

Why do my onions make me cry?

You are crushing the cell walls instead of slicing them. A razor-sharp knife slices through cells cleanly, keeping the irritating compounds contained.

Should I keep the root on?

When slicing, keep the root intact until the very end. It acts as an anchor that holds the layers together while you make your cuts.
