TL;DR

  • The non-slip feet and hand guard actually work, making this mandoline safer and more stable than most.
  • Slices firm vegetables like potatoes and carrots cleanly and consistently across a wide range of thicknesses.
  • The blade smushed soft vegetables like tomatoes instead of slicing them, which is a core limitation.
  • Julienne cuts require excessive force and produce inconsistent results; avoid relying on them.
  • Cleanup requires disassembling and hand-washing multiple blades and parts, which takes about five minutes.

OVERVIEW

What you need to know

The OXO Mandoline Chief is the mandoline I'd actually reach for if I'm slicing vegetables for a crowd. It's stable, the guard works, and it handles firm vegetables consistently. The blade struggles with soft foods and the julienne cuts require more force than they should, but for straight slices at various thicknesses, it delivers.

THE VERDICT

OXO Mandoline Chef Stainless Steel Slicer with Guard

“Stable and safe for firm vegetables, but the blade struggles with soft foods and the julienne cuts require excessive force. Worth it if you're slicing potatoes and carrots for crowds; skip it if you need a one-tool solution.”

I scored it 72 out of 100. The bench rubric lands it in the low-70s because the blade design excels at firm vegetables but fails on soft ones, the julienne settings are awkward, and cleanup requires disassembling multiple parts. What carries it to 72 is the stability and safety: the non-slip feet don't budge, the hand guard actually protects your fingers, and the dial adjustments are clear and easy to use. Across 3,000 Amazon reviews averaging 4.3 stars, owners consistently praise the stability and guard effectiveness, and 400+ buyers picked one up last month, which suggests it's earned enough trust to stay in regular rotation.

The real limitation is the blade itself. It slices potatoes, carrots, cucumbers, and apples cleanly and consistently. The moment I tried a tomato, the blade smushed instead of sliced. This isn't a flaw in execution; it's a design constraint of how mandoline blades work on soft foods. If you're cooking for a crowd and slicing firm vegetables, the OXO handles that job reliably. If you're hoping for a one-tool solution that replaces your knife for everything, keep looking.

The julienne blades are a weak point. Both the thin and thick settings require noticeably more force than the straight blade, and the results are inconsistent. I'd avoid relying on them. The guard's short prongs occasionally let food shift, but nothing dramatic. Cleanup is straightforward but time-consuming: you disassemble the blades and parts, hand-wash them, and reassemble. At just under $100, you're paying premium money for a tool that won't replace your knife, but if you regularly slice vegetables for crowds, it earns its counter space.

FREQUENTLY ASKED

Questions we hear every week.

Is the OXO mandoline actually sharp enough to slice soft vegetables?

No. The blade is designed for firm vegetables like potatoes, carrots, and cucumbers. Tomatoes, peppers, and other soft foods get smushed rather than cleanly sliced. If you need to slice a lot of soft vegetables, a sharp knife is still your best bet.

How does the hand guard compare to other mandolines?

The OXO's guard is one of the better ones I've tested. It holds food securely and keeps your fingers far enough away that you feel safe using it. The short prongs occasionally let food shift, but it's a minor issue compared to guards that barely grip at all.

Can you use the julienne blades regularly?

You can, but they require more force than the straight blade and the results are inconsistent. If julienne cuts are central to your cooking, look for a tool specifically designed for that. For occasional French fries or carrot sticks, the OXO works, but it's not ideal.

Is it worth $92?

If you regularly slice firm vegetables for crowds and want a stable, safe mandoline, yes. If you're hoping for a one-tool solution that handles everything from potatoes to tomatoes, no. The price is fair for what it does well, but it's not a bargain and it won't replace your knife.

How long does cleanup actually take?

About five minutes if you disassemble and hand-wash the blades and parts. The unit folds flat for storage, which is convenient, but there's no way around the fact that you're cleaning multiple pieces after each use. If quick cleanup is a priority, factor that into your decision.
