Step-by-Step Guide to ‘Ui in Halve Ringen Snijden’
Here’s how to slice an onion into half rings in a clean and controlled way:
1. Peel the Onion
Begin by removing the dry, papery outer skin of the onion. Cut off the stem end (the top) but leave the root end intact this helps keep the layers together while cutting.
2. Slice the Onion in Half
Place the onion on your cutting board with the root end facing one side. Using a sharp knife, slice the onion in half vertically from the root end to the top. This gives you two equal halves that each display a crescent-shaped pattern of layers.
3. Position the Onion Half
Lay one half flat-side down on the board for stability. Make sure the root end is pointing away from your knife hand.
4. Begin Slicing
Hold the onion with a claw grip fingers curled under to avoid cutting yourself. Start slicing from the top end toward the root, making parallel cuts that are as thick or thin as needed. Most half rings are between 1 to 3 millimeters thick depending on the desired texture and use.
5. Stop Before the Root
Once you reach the end close to the root, stop slicing. Discard the root or save it for making broth. Repeat with the other half of the onion.
Tips for Perfect Half-Ring Onions
Keep Your Knife Sharp
A dull knife crushes the onion’s cells, causing excessive tears and uneven cuts. A sharp knife glides through the layers and keeps your slices neat.
Use Uniform Motion
Slice with a smooth rocking motion, maintaining even pressure. Don’t saw through the onion, which can produce jagged or uneven rings.
Chill the Onion First
If you’re sensitive to the sulfur compounds that cause eyes to sting, chill the onion in the fridge for 15 minutes before cutting. This slows the release of irritating compounds.
Control the Thickness
Thinner slices cook faster and are ideal for raw dishes. Thicker slices hold their structure during grilling or long simmering.
Culinary Applications for Half-Ring Sliced Onions
Onions sliced in half rings are incredibly versatile. Here are some creative uses in everyday cooking:
Raw in Salads and Sandwiches
Red or sweet onions cut into fine half rings add crisp texture and zing to salads. Soaking them in cold water for 10 minutes can reduce harshness.
Caramelized for Toppings

In Pickles

In Curries and Stews

Storing Half-Ring Onions
If you have sliced more onion than needed, storing it properly will preserve its freshness:
- Place slices in an airtight container.
- Refrigerate and use within 35 days.
- Avoid storing near fresh fruit, as onions can absorb their aromas.
Safety and Hygiene
Always wash your hands, knife, and cutting board after cutting onions to prevent cross-contamination, especially if you plan to work with raw ingredients like meat or fruit afterward.
Avoiding Tears
Besides chilling the onion, you can try cutting near a running fan or slicing under a kitchen hood vent to disperse onion fumes. Wearing kitchen goggles is also an option for frequent cooks.
