Oblique Cut

What Is an Oblique Cut?

The oblique cut, also called a roll cut, is a knife technique used mainly for long, tapered vegetables such as carrots and parsnips. Each piece is cut on an angle, and the vegetable is rotated between cuts to create pieces with alternating sloped surfaces. The cut produces an attractive shape and exposes more surface area for cooking and sauce coating.

How to Make a Roll Cut

1. Trim and peel the vegetable as required, then place it securely on a stable cutting board.
2. Hold the knife at an angle and make the first diagonal cut.
3. Rotate the vegetable approximately a quarter turn.
4. Make the next diagonal cut at the same angle and distance from the previous cut.
5. Continue rotating and cutting until the vegetable is portioned into even pieces.

Why Chefs Use the Oblique Cut

The angled surfaces create an attractive presentation and increase the exposed surface area compared with a straight cylinder cut. This can help the pieces cook evenly and allows sauces or glazes to cling to more of the vegetable. Consistent size remains important for even cooking.

Common Mistakes

• Changing the angle or rotation inconsistently, which creates irregular pieces.
• Cutting pieces too large or too small for the cooking method.
• Using a dull knife or an unstable board, which reduces control.
• Rotating the vegetable away from the blade path rather than keeping a safe guide-hand position.

Chef’s tip: Practise with a carrot of even thickness and keep the knife angle and rotation consistent. The goal is a series of similar pieces, not simply diagonal slices.
