Best Mandoline Slicer Deals: 15 Picks From $20 to $56

There are two thickness mechanisms. A dial raises and lowers the blade on a continuous scale, so you can pick any thickness. Interchangeable inserts give you fixed settings, usually three to five, and often include a julienne comb. A dial is more flexible for everyday cooking; inserts tend to hold their setting better and are less likely to slip mid-slice.

Blade material decides how long the tool stays sharp. Stainless steel blades hold an edge and resist rust; the thin wire-like blades on very cheap models dull within a few uses and start tearing tomatoes. The frame matters too: a folding plastic frame with non-slip feet is easy to store, while a stainless V-slicer on a stand is more stable for big batches but takes up a shelf.

Every mandoline should ship with a food holder or guard, and you should use it for the last third of every vegetable. The exposed blade is the whole point of the tool and the whole risk. If the guard feels flimsy or does not grip a slippery onion, that is a reason to hesitate about the model, not to skip the guard. A cut-resistant glove is a cheap belt-and-braces addition for anyone who slices a lot.

Best overall adjustable slicer

The is the pick most cooks land on: a dial for thickness, a food holder that actually grips, and a blade that stays sharp. If you want the same reliability in a set with interchangeable blades, the adds julienne and grate inserts for not much more.

Best budget adjustable slicer

The is the value pick at around twenty-five dollars, and the is a similar price with a simpler safety guard. For a touch more you get the , which feels sturdier under a heavy potato.

Best V-slicer

The classic V-shaped mandoline cuts with a straight blade and is stable over a bowl. The is the long-running name in that design. The is the heavier-duty version for volume work.

Best multi-blade chopper set

If your goal is more than slicing, the and the combine a slicer with dicing grids, so you can cube onions and peppers too. The is a popular used option if you want the grater drums included.

Best for safety-first shoppers

The leans into the guard and grip rather than blade count. The is a used pick with a treated surface, and the is a good used deal if you already trust the KitchenAid inserts.

Set the thickness before you start, not while a vegetable is on the blade. Slice with a smooth, even push rather than a sawing motion, and let the blade do the work. Stop and switch to the guard as soon as the vegetable is small, even if it feels wasteful; the last slice is not worth a fingertip. Hand-wash and dry immediately, because even stainless blades pit if left wet, and never put a mandoline in the dishwasher unless the maker confirms it is safe, since heat warps the plastic frame and dulls the blade. Store it with the blade retracted or the guard in place. If you slice a lot of produce, a good [cutting board](/g/best-cutting-board-deals-200) underneath gives the feet something to grip and keeps the blades away from your counter.

A dial mandoline produces three families of cut. Straight slices at two to three millimetres are the everyday setting for gratins, oven chips and cucumber salad; thinner slices crisp better, thicker slices hold up in a bake. A julienne comb makes matchsticks for slaw, stir-fry and shoestring fries, though soft vegetables like tomato will collapse. A grate blade handles cheese, carrots and hash-brown potato, and is the setting people forget a mandoline can do. You do not need every blade: a 2 mm slice, a 4 mm slice and one julienne comb cover almost all home cooking.

Buy an adjustable stainless mandoline with a dial and a guard that grips, spend twenty-five to forty dollars, and use the guard every time. A V-slicer is the sturdier choice for big batches, and a multi-blade chopper earns its keep only if you also want to dice. Never rush the last slice.
