Mueller Pro-Series 10-in-1 Vegetable Chopper Review: Easy, Even Dicing

As an Amazon Associate I earn from qualifying purchases. Disclosure

Overview

Mueller’s Pro-Series 10-in-1 is a press-down vegetable chopper built on a 7.5-cup container: you set food on a blade grid, close the clamshell-style lid, and the pieces drop into the container underneath. Mueller sells it as the 8 Blade Original Chopper Pro (model MC-780) in four colors, and the kit pairs two dicing grids, 1/2-inch and 1/4-inch, with six more blades for straight slices, wavy slices, julienne strips and grating. It is for home cooks who prep a lot of onions, peppers and potatoes and would rather not do all of it with a knife.

Push-down choppers are everywhere, and many are hard to tell apart. What separates this one is its record in independent tests: Food & Wine calls it its top vegetable chopper, Sporked rated it 9 out of 10 as its best chopper-and-slicer combination, and in Reviewed’s head-to-head with the Fullstar, the Mueller came out ahead.

Key Specifications

Mueller Pro-Series 10-in-1 Vegetable Chopper Dicing Performance

The dicing grids are the reason to buy it, and the tests agree on two points: the pieces come out even, and pushing the lid through takes little effort. Food & Wine found the Mueller needed the least pressure of all the choppers it tested; half an onion came out in uniform pieces, and potatoes gave it no trouble. Sporked’s tester liked the strip of rubber on top of the lid, which stops a pressing hand from sliding off.

In Reviewed’s side-by-side test, sharper blades made the difference: celery that jammed in the Fullstar went through the Mueller easily, and its cuts were cleaner.

What it handles well depends on the food, and some prep never goes away: onions, carrots and garlic still need peeling, and anything wider than the grid has to be cut down first. Very thick pieces are trouble, too; in Reviewed’s test, whole baby corn jammed in the small dicer. Soft foods are hit and miss. Reviewed warns that soft ingredients can make a frustrating mess, and in its test mushrooms got stuck in the grid while tomatoes squirted across the table; SimplyCanning, testing the Fullstar, got an even tomato dice by halving and coring the tomatoes and setting them skin side down. For fibrous stalks such as celery and asparagus, Reviewed’s advice for any chopper is to push hard, though the Mueller’s sharper blades took celery easily. Garlic is the other gap: Sporked found the cloves too small for it. Because every vegetable lands in the same container, a recipe that adds ingredients at different times means emptying it between them.

Owner feedback is strongly positive across a very large number of buyers, and it centres on time saved: owners say prep goes much faster, they like having so many blade options, and they find it sturdy and easy to take apart.

Slicing, Julienne and Grating Blades

The other six blades turn the same box into a mandoline-style slicer and grater. They fit a separate blade holder, and the set covers straight slices, wavy slices, julienne strips and three grater blades for vegetables, cabbage or cheese. A safety food holder keeps small vegetables from slipping while you slice them.

This half of the kit has had less scrutiny than the dicer. Sporked tested only the chopping function of chopper-and-slicer combinations, and none of the tests we found measured the slicing or grating blades on their own. Reviewed did count the larger set of useful attachments as one reason the Mueller beat the four-blade Fullstar. Treat the slicers as a handy extra for salads, slaw and garnishes rather than a replacement for a dedicated mandoline.

Cleaning, Size and Storage

Cleanup is easier than the number of parts suggests. The blades release with the push of a button, every part can go on the top rack of the dishwasher, and Mueller includes a cleaning fork and brush for food left in the grid. That fork earns its place: Reviewed found that once food sticks in the grid, digging it out square by square takes a long time.

Storage is the real cost. Mueller lists the chopper at up to 11 inches long, 6 wide and 5 tall, and Sporked pointed out that at nearly a foot long it takes up real cabinet space, with the spare blade inserts needing a safe home of their own.

The safety details are sensible for a tool full of open blades: a blade lock, the food holder for slicing, and BPA-free, PFAS-free food-grade materials, according to Mueller.

How Does It Stack Up Against the Competition?

The Fullstar Pro Original is the Mueller’s most direct rival, another press-down dicer with a catch container; the OXO and the Kuhn Rikon chop in different ways, with a plunger and a pull cord.

Mueller Pro-Series 10-in-1 Vegetable Chopper: Worth It for Even Dicing

It’s worth having for cooks who prep several vegetables at once for a chopped salad, salsa, soup base or stir-fry, where everything is headed for the same pan or bowl anyway. Reviewed’s tester found it a quick way to get vegetables ready for fried rice, and the two grid sizes cover both a medium chop and a small dice. If you also slice vegetables or grate cheese often, those jobs come in the same box.

Look elsewhere if you mostly need garlic, herbs or a fine mince: the Kuhn Rikon Pull Chop, Sporked’s top-rated chopper, gets finer the more you pull its cord, and its 2-cup bowl is far easier to put away. The OXO Good Grips Vegetable Chopper is the simpler tool for small jobs such as mincing garlic. And weigh Reviewed’s verdict before buying any chopper: even after preferring the Mueller to the Fullstar, it concluded that unless a knife is hard for you to use, a chopper is probably more trouble than it is worth, because peeling and cutting food to fit the grid, then cleaning the attachments, made chopping by hand much faster in its test.
