I Tested 8 Mandolines to Find Ones That Could Slice with Ease

Mandolines make it easy to slice uniform pieces of food—think French fries or rounds of zucchini for a provincial tian. (My husband also swears a mandoline is key to perfectly shaved pieces of onion for smash burgers.) A good one makes it easy to slice without a hitch—literally.

In past testing, we focused on mandolines under $50 (give or take a few bucks). This time, I expanded the lineup to see if pricer mandolines were any better. I reviewed a selection of eight mandolines and included handheld models as well as those with stands. I sliced potatoes, lemons, and tomatoes (and an extraneous cucumber because why not?) to find a mandoline that was sharp, easy to use, and a cinch to clean.

The Winners, at a Glance

The Best Mandoline

OXO Good Grips V-Blade Mandoline Slicer

$46 $39 at Amazon $46 at Target View on Webstaurant Store

This was our winner in our previous testing, and it's stood the test of time. It cleanly and effortlessly sliced (almost) everything, and I never felt like I'd cut myself using it. The only time it struggled a bit was slicing potatoes into french fries, but it still produced perfect batons. 

The Best Safety Mandoline

Dash Safe Slice Mandoline

$40 $37 at Amazon $50 at Sur La Table $35 at Samsclub.com

This safety mandoline looked like quite the complicated contraption, but it was actually easy to use (even if it did kind of work like a guillotine). I had no issues slicing tomatoes, lemons, and potatoes into paper-thin slices—and I felt safe doing so. It also did a solid job of slicing potatoes for fries, though they were a bit stumpy. 

The Best Handheld Mandoline

Microplane Adjustable Mandoline Food Slicer

$40 at Amazon $40 at Williams Sonoma $40 at Walmart

This was a sharp, no-frills mandoline that got the job done, easily slicing potatoes, tomatoes, and lemons. And, if you need to julienne produce into thin matchsticks, it does that, and it does it well. 

The Tests

• Slice Potato Test: I sliced Yukon gold potatoes into thin, medium, and thick slices using each mandoline (half the time I used a cut-resistant glove, and the other half I used the mandolines’ hand guards if they had them). If the mandolines were scary to use (read: the potatoes got stuck on the blade) during this test, I discounted them from further testing. 
• Slice Tomato Test: Since tomatoes are tricky to slice thinly with a knife, I wanted to see how the mandolines fared when slicing them into thin rounds. I only used mandolines that made it through the first round of testing. 
• Slice Lemon Test (Winners-Only): I used each of my favorite mandolines to thinly slice lemons into rounds. 
• Cutting French Fries Test (Winners-Only): After swapping out the blades or turning the adjustment knob to the thick julienne setting on our favorite mandolines, I used them to slice up potatoes into french fries. 
• Cleaning and Usability Tests: I examined how easy each mandoline was to assemble (including switching out blades) and use, as well as if it was difficult to clean. I also washed applicable mandolines in the dishwasher and noted any damage. 

What We Learned 

A Sharp Blade Was Key

As with a sharp chef's knife, a sharp mandoline blade made cutting foods effortless, with no food catching on the blade edge. This was also true for cutting french fries, which adds vertical blades to the mix (i.e. more things for your food to catch and get stuck on). What was scary was when whatever food I was trying to slice (mostly hard foods, like potatoes) got stuck on the blade. This puts you in a dangerous situation where you have to decide whether to continue to push the food through or try to wiggle it back up out of the blade. I had this issue with half of the mandolines, namely the OXO Handheld Mandoline Slicer, OXO Chef's SteeL Mandoline 2.0, OXO Good Grips Chef’s Mandoline Slicer 2.0, and Börner V Power Mandoline. Since they felt unsafe to use—and produced raggedly cut potatoes—I disqualified them from further testing. 

We Liked Mandolines with Minimal Parts

While this wasn’t a dealbreaker, two of my winners—the OXO Good Grips V-Blade Mandoline Slicer and Dash Safe Slice Mandoline—had lots of parts and were a tad tricky to reassemble after dismantling for cleaning. The OXO V-Blade, while a great mandoline, proved particularly puzzling; I had issues reattaching the multiple parts, and the user manual wasn’t helpful (I wound up watching a video on YouTube to figure it out). The Dash mandoline was easier to assemble but also had multiple parts, including a tube where you place your food, a dish where cut foods fell into, and an insert to push food against the blade. On the other hand, my favorite handheld pick from Microplane was uber simple to assemble; for example, to switch to a julienne setting, you just flip the straight-edged blade over to the julienne side and slot it in. 

Handheld vs. Kickstand Mandolines: Which Were Better?

Some mandolines have a collapsible leg that can be used to prop up the blade on a counter or table—you can slice without holding the mandoline steady with your other hand. The OXO V-Blade Mandoline was a prime example of the "kickstand" model. I tended to prefer mandolines with stands since it made it easier to focus on evenly slicing your ingredients, though I did find the handheld offering from Microplane (which was sans stand) still relatively comfortable thanks to its grippy handle. In terms of safety, kickstand mandolines are less prone to accidents, because there's no danger of them slipping in hand.

Clearly Marked Measurements Were Helpful

While being able to make micro-adjustments on the Benriner was useful, I didn’t really know what I was getting with each turn of the knob. Instead, I preferred mandolines with clearly marked measurements or markers, which gave me a better idea of how thick the results would be without wasting food. My winner, the OXO V-blade, had clearly marked lock, unlock, 1/16" (1.5mm), 1/8" (3mm), 3/16" (4mm), and 1/4" (5mm) markings, making it easy to know what results I'd get. While the Dash didn’t have measurements on the adjusting knob, it did feature numbers (one to eight) that gave you a general idea of thickness, with one being the thinnest and eight the thickest. 

Cutting Fries Was Challenging

My favorite mandolines made slicing easy, but cutting potatoes into fries was a little more challenging. While my winner from OXO cut perfectly proportioned fries, I struggled to push the spuds through the vertical blades. The Dash cut fries quite easily, though they were a little bit on the thick and short side since the chute where you place the potatoes was small, and we had to trim the potatoes to fit. The Microplane created more of a shoe-string fry cut, which wasn't what I was looking for.

While I avoided making fries with mandolines knocked out during the first round of testing, I was curious and tried an errant go at cutting fries with the OXO Chef’s Steel Mandoline 2.0 and Benriner—both were disappointing. The potatoes immediately got stuck on the vertical blades of both mandolines, making it dangerous to push the spuds through, so I had to remove the potatoes without finishing slicing them. 

Other Gear You Need to Use a Mandoline

• Mixing bowls are especially helpful when using a handheld mandoline—you can set the mandoline over the bowl and slice directly into it. You can find our top picks here.
• A roomy cutting board is ideal for slicing large batches—we've recommended our favorite wooden and plastic boards for years.
• A Y-Peeler is handy for prepping fruits and vegetables before you slice them—easily slice away tough potato skin or blemishes on an apple.
• Cut-resistant gloves will keep your hands safe, even if the mandoline slips or your fingers get too close to the blade.

The Criteria: What to Look for in a Mandoline

My favorite mandolines were sharp, deftly slicing hardy and soft ingredients. They also were easy to adjust, with clear markers indicating thickness. Finally, while I liked mandolines that were simple to assemble and clean, this wasn’t a dealbreaker. 

Our Favorite Mandolines

The Best Mandoline

OXO Good Grips V-Blade Mandoline Slicer

$46 $39 at Amazon $46 at Target View on Webstaurant Store

What we liked: This was a very sharp mandoline that cut potatoes, tomatoes, and lemons cleanly and efficiently—there was no resistance when slicing. While I did face more resistance when cutting fries, the results were the perfect thickness and had nice, clean edges. I also liked the optional fold-out stand, which made it easy to prop the mandoline up on a cutting board or over a bowl. 

What we didn’t like: The biggest peeve I had with this mandoline was that it was difficult to put together after taking it apart for cleaning; for example, to slot the blade in, you have to handle it uncomfortably close to the end of its blade. This has continued to be an annoying struggle as I've used it in long-term testing. I also found it slightly difficult to cut french fries, though the results were near-perfect. 

Key Specs 

• Thickness settings: 4
• Blade style: V-blade
• Accessories/Features: Fold-out stand, handguard
• Dimensions: 15.25 inches long; 3.13-inch-wide blade section; 1.13 inches thick
• Care instructions: Hand-wash

The Best Safety Mandoline

Dash Safe Slice Mandoline

$40 $37 at Amazon $50 at Sur La Table $35 at Samsclub.com

What we liked: This mandoline had a guillotine-like setup which we were skeptical of at first, but I wasn't surprised with how well it worked. To use it, place your food into the chute, press the insert against it, and pump the white handle attached to the blade downwards to slice. It was easy to use, and there was no chance of cutting yourself, not to mention every slice (even the thinnest) was perfectly even. It also did a surprisingly good job of slicing fries (though they were just a hair thicker than desired).

What we didn’t like: The chute and cutting areas are quite small, so you have to cut food down to fit it inside, which makes for some odd-shaped results. And while they provide a little brush for you to clean your blade, I still found it slightly difficult to clean all the nooks and crannies. 

Key Specs: 

• Thickness Settings: 8
• Blade Style: Angled
• Accessories/Features: Fold-out stand
• Dimensions: 12 inches long; 3-inch wide blade section; 1.75 inches thick
• Care instructions: Hand-wash

The Best Handheld Mandoline

Microplane Adjustable Mandoline Food Slicer

$40 at Amazon $40 at Williams Sonoma $40 at Walmart

What we liked: This handheld blade was sharp, sturdy, and shaved with consistent results. It’s a great option for someone who might not need a whole mandoline getup and just wants to thinly slice a few things now and then. It's held up nicely over long-term testing, though the blade has dulled and it would be nice if they sold replacement blades.

What we didn’t like: The thickest setting isn’t very thick, meaning if you want to use this mandoline to make French fries, you’ll get shoestring fries. The adjustment knob is also unmarked, so you’re more in the dark on what thickness your results will be. 

Key Specs: 

• Thickness settings: NA (continuously adjustable)
• Blade style: V-blade
• Accessories/Features: Handguard
• Dimensions: 14.25 inches long; 3.8-inch wide blade section; 0.8 inches thick
• Care instructions: Dishwasher-safe (though we recommend hand-washing anything with a blade)

The Competition

• OXO Good Grips Handheld Mandoline Slicer: While this handheld mandoline cut cleanly and without any resistance, the bottom plastic part wasn’t flush with the bottom of the blade. So, every time I sliced, whatever I was slicing hit that ridge. 
• Benriner Mandoline Slicer: While this was a fantastic mandoline for cutting paper-thin slices of, well, anything, it wasn’t easy to adjust; sometimes the plastic part that moves up and down got stuck. It also did terribly when trying to cut potatoes into fries—the potato got stuck, and the resulting fries had frayed edges.
• OXO SteeL Chef's Mandoline 2.0: This pricey mandoline performed poorly, and it took a lot of effort (and nerves of steel) to push a potato fully through the blade. The same thing happened when I tried making fries with it. 
• Börner V Power Mandoline: This was a clunky mandoline that couldn’t cut potatoes without them getting stuck on the blade. 
• OXO Good Grips Chef’s Mandoline Slicer 2.0: Almost identical to the OXO Chef’s SteeL Mandoline, this one performed just as badly; it was scary to use, and potatoes got stuck on the blade. 

FAQs

Can you sharpen the blades on a mandoline?

Some of the mandolines I tested do offer the option of sharpening their blades, namely the Benriner. If you have this mandoline and are interested in sharpening the blades, I recommend getting it done by a professional sharpener.

What is a mandoline good for?

Mandolines make slicing fast and accurate, and they’re great for keeping your cuts consistent. I like using them to slice up vegetables for salads, fruits for desserts (think thinly sliced apples for invisible apple cake), and eggplants for eggplant parm. Not to mention they are great for slicing up potatoes to make homemade potato chips or potato gratin. 

What is the safest way to use a mandoline?

If you’re new to using a mandoline, we recommend investing in a cut-resistant glove—it can’t hurt to be extra safe as you learn. Another option for safe cutting is using the guard that often accompanies a mandoline, though I often found them a bit clunky. During testing, I also found that a sharp blade makes slicing less dangerous—dull blades caused foods to get stuck, which meant I had to apply more pressure to push food through the blade, increasing the chance of our hand slipping and cutting ourselves.

What is the best way to clean a mandoline?

Most of the mandolines I tested were not dishwasher-safe, and I recommend careful hand washing with warm, soapy water before drying. If your mandoline is dishwasher-safe, you can go that route, though washing any parts with blades by hand will ensure their longevity.

What's the best mandoline for beginners?

Any mandoline with a safety guard is a good choice for a new cook or someone learning how to use a mandoline. The guillotine-style slicing mechanism of the Dash Safe Slice is a good option.
