Best mandoline slicers 2026

Mandoline slicers look intimidating and should always be used with care, but our tests have found that the best are not only safe, but convenient and efficient.

We put mandolines from Joseph Joseph, Lakeland, Oxo Good Grips, ProCook and more to the test, including freestanding slicers and handheld ones that you place over a bowl. Our panel of testers sliced their way through mountains of sweet potatoes and tomatoes to find out which ones have the edge.

Two mandolines impressed us enough to be named Best Buys, and one earned our Great Value recommendation, thanks to its consistent slices and budget-friendly price.

How we test mandoline slicers

We buy the bestselling mandoline slicers and put them through our robust objective tests. We also ask a panel of testers to rate the experience of using every single mandoline slicer. We don't accept freebies from product manufacturers or retailers.

We regularly revisit the mandoline slicers on sale to see if there are any popular models that need testing – when we find them, we do. 

Slicing consistency and adjustability

• We use every mandoline slicer to cut slices of hard (sweet potato) and soft (tomato) foods to assess blade sharpness and consistency.
• Every mandoline is used on a thin, medium and thick setting, provided they have these settings.
• We use a digital thickness gauge to work out the average thickness of the slices, then check how often they deviate from that average to find out which mandolines produce the most consistent slices.
• We also take into account the number of thickness settings and cutting styles.

Ease of use and cleaning

• A panel of our testers use each mandoline and judge how straightforward they are to set up, adjust and slice.
• After testing, we clean each mandoline by hand to see if food bits get lodged in any annoying little crevices.
• While some mandolines make it a breeze to hold food in the gripper and glide it back and forth over the blade, others are more fiddly and require more effort. 

Safety and build quality

• We assess how securely the blade can be locked away when you've finished using the mandoline and how much shielding the food gripper provides. We also check for any loose parts or mechanisms that might put you at risk of touching the blade by accident.
• None of the mandoline slicers we tested are unsafe, but some require much more care than others.
• Our panel of testers also judge how sturdy and well made they are.

What is a mandoline slicer?

Mandoline slicers are a kitchen tool used for slicing and julienning foods into uniform pieces. You get handheld mandolines that you place over a bowl and freestanding models with a foot to hold it up above the kitchen countertop.

There is usually a flat 'track' on top with a blade embedded into it. You hold the food using the included food gripper, so your fingers are kept away from the blade, then slide it back and forth along the track. Each time the food passes over the blade, it produces a slice that drops underneath the mandoline.

Mandolines often have multiple thickness settings that adjust the position of the blade, so you can achieve thicker or thinner slices.

Some have several different cutting options besides slicing, too. We've tested mandolines that can julienne at different thicknesses, grate foods, and cut them into waffle or crinkle cuts.

Keep your blades effective and sharp with the best kitchen knives and best knife sharpeners.

Five things we learned testing mandoline slicers

1. Most vegetables need to be cut into smaller sizes before being sliced with a mandoline. Ideally, you want a flat surface at the top and bottom before you start slicing, so it's easier to keep food firmly held in the gripper.
2. Mandolines often produce less consistent slices when tasked with producing thicker ones.
3. Some mandoline blades can be left slightly exposed when the mandoline is not in use, so you’ll need to be careful about where you store it and make sure you don't accidentally touch the blade when you pick it up.
4. Only a handful of the mandolines we tested have a slicing blade that can be removed and sharpened; the rest will become less effective when the blade starts to dull.
5. The food grippers on mandolines often leave you with a bit of vegetable left over that can’t be sliced, so you're likely to end up with a little more food waste.
