What You Can Slice With It
An onion slicer works best with firm vegetables and fruits, including:
-
Onions (yellow, red, or white)
-
Potatoes (for chips or scalloped dishes)
-
Cucumbers (for salads or pickles)
-
Zucchini or summer squash
-
Apples (for pies or snacks)
-
Carrots (if they aren’t too thick)
Avoid using it with:
-
Soft fruits like bananas or tomatoes
-
Very hard roots such as sweet potatoes or beets
-
Foods with tough cores
How to Use It Safely and Effectively
Follow these simple steps:
-
Place the slicer on a stable surface (a non-slip mat helps).
-
Trim the ends of the vegetable so it sits flat.
-
Press firmly and evenly through the blades using a pusher or the heel of your hand.
-
Rinse the slicer immediately after use, as food can get stuck between the blades.
-
Dry it thoroughly to prevent rust (metal models) or odor buildup (plastic models).
Pro tip: Sprinkle sliced onions with a pinch of salt to soften their sharp flavor and bring out natural sweetness.
Found One at a Thrift Store? Clean It First
If you bought your slicer secondhand, make sure to clean it thoroughly.
Steps to sanitize it:
-
Soak it in warm, soapy water
-
Use an old toothbrush to scrub between the blades
-
Sanitize with vinegar or a diluted bleach solution
-
Check for rust or dull blades
If the blades are damaged or unsafe, it’s best to recycle the tool safely.
