At the Good Housekeeping Institute Kitchen Appliances and Innovation Lab, we test thousands of products each year including hundreds of kitchen gear items from electric knives to non-stick cookware to air fryers. To find the best madoline slicers, we sliced a variety of fruits and vegetables including tomatoes, potatoes and thick-skinned eggplants and considered things like how easy each product was to use, clean, assemble the blades and adjust the thickness. We also looked at the hand protectors, non-slip feet, handles and overall safety (which is the most important factor of choosing the best mandoline).
