Can You Dice Onions On OXO Good Grips V Slicer?

Short answer: Yes, the OXO Good Grips V-Blade Mandoline Slicer can be used to dice onions, but it would require extra steps because it primarily slices, no dice.

The OXO Good Grips V-Blade Mandoline Slicer is a versatile kitchen tool, designed for slicing various fruits and vegetables, including onions. Although its main function is to create uniform slices, with a bit of extra cutting after slicing, you can achieve a diced result. Please note that for perfect cubes or a true dicing effect, you may need a dedicated dicing tool or to use a knife.

Efficient Slicing: The V-Blade Mandoline Slicer is designed to create perfectly even slices, juliennes, and crinkle cuts more quickly than using a knife and cutting board.

Ideal for Soft Fruits and Vegetables: This slicer is especially useful for softer fruits and vegetables like tomatoes, plums, or peaches.

Non-Stick Design: The textured ridges on top of the mandoline help prevent food from sticking, which is particularly beneficial when slicing stickier vegetables like potatoes, beets, or radishes.

Easy Blade and Thickness Adjustment: The Mandoline Slicer makes it easy to switch between blades and adjust slice thicknesses, from as thin as 1/16 of an inch to as thick as 1/4 inch. All blades are stored securely underneath the mandoline for convenient access.

Safety Features: The food holder, equipped with four metal tines, ensures your fruits and vegetables are held securely while slicing, and more importantly, keeps your fingers away from the blade. The non-slip feet enable quick slicing without the mandoline moving around.

French Fry Blade: The Mandoline Slicer includes a french fry blade that can be swapped in to cut perfect sizes for french fries.

Easy Cleaning: While the blades require hand washing, the body, and food holder are dishwasher safe (top rack).

Can You Dice Onions On OXO Good Grips V Slicer?

While the OXO Good Grips V-Blade Mandoline Slicer is an excellent tool for slicing a variety of fruits and vegetables, including onions, it’s not explicitly designed for dicing. Dicing typically involves cutting food into cubes, which requires a second cut perpendicular to the slices. The OXO slicer can provide the initial thin, uniform slices, but the second cut to turn these slices into dice would need to be done manually with a knife. So, in essence, while it can aid in the process, it won’t directly dice onions.

Can you dice with a mandolin?

Typically, a mandoline is used for slicing, not dicing. However, some mandolines come with attachments that allow for julienne cuts, which can be used as a first step to dicing. You would then need to use a knife to cut the julienne strips into dice. It’s important to note that the size of the dice would be determined by the thickness setting on the mandoline.


While the OXO Good Grips V-Slicer is an excellent tool for achieving uniform slices and julienne cuts, it’s not specifically designed to dice onions. To dice an onion with this slicer, you would first have to use the julienne blade to make long, thin strips, and then manually cut those strips into smaller pieces using a knife. However, this process may not provide the precision and uniformity typically associated with diced onions. It’s important to note that while mandoline slicers like the OXO Good Grips V-Slicer add great convenience and speed to many kitchen tasks, for tasks such as dicing, a good chef’s knife might still be the most effective tool.
