In this article, we’ll show you how to cut an onion without crying, and with step-by-step instructions, you’ll be slicing onions like a pro in no time.

Before You Start: Gather Your Tools

Before you begin to cut an onion, it’s necessary to have the right tools on hand. Here’s what you’ll need:

Sharp knife Cutting board Bowl of water

A sharp knife is essential for making precise cuts and reducing the likelihood of injury. A cutting board should be used to provide a stable surface to work on. Finally, having a bowl of water nearby can help to minimize eye irritation by washing away any airborne onion particles.

Step-by-Step Guide: How to Cut an Onion

Step 1: Prep the Onion

Begin by selecting a firm, fresh onion. Avoid any with soft spots or signs of mold. Rinse the onion under cold water and pat it dry with a clean towel. Next, cut off the root and stem ends using a sharp knife. Slice the onion in half from the top to the bottom.

Step 2: Remove the Skin

Peel off the outermost layer of skin by making a small incision near the stem end and gently pulling it away. You can use your knife to loosen any stubborn bits of skin.

Step 3: Make the First Cut

Place one half of the onion, cut side down, on the cutting board. Using a sharp knife, make a vertical cut through the onion from the top to the bottom. Avoid cutting all the way through the root end, as this will help to keep the onion together while you slice it.

Step 4: Slice the Onion

With the flat side of the onion down, make horizontal cuts across the top of the onion, holding the onion steady with your non-dominant hand. Make sure the cuts are evenly spaced, and try to cut all the way to the root end without going through it.

Finally, turn the onion so that the flat side is facing upwards and make your final cuts from the top to the bottom of the onion. Repeat with the other half of the onion.

Step 5: Store Your Onion

If you don’t need to use all of your onion right away, store the unused portion in an airtight container in the refrigerator. You can also freeze chopped onions in a freezer-safe bag to use later in recipes.
