Built for Real Meal Prep

The four details that make the PrepGrid 14 last longer and work faster than the choppers already in your cabinet.

420-J2 Steel Dicing Grids

0.6mm blades hardened to 54 HRC and set deep in a reinforced collar. They stay straight on raw sweet potato and cut ripe tomato cleanly.

Shatter-Resistant 1.5L Basin

A BPA-free clear tub with measurement marks and four non-slip feet. It holds 6.3 cups of prep and grips wet counters.

Much Faster Prep

Our 4-lb chili batch took 32 minutes by hand and 3 minutes 40 seconds with the PrepGrid, including blade swaps.

Finger-Safe Slicing Guard

A clip-on hand guard with stainless prongs holds the vegetable for you, so your fingertips stay well clear of the slicer and julienne blades.

How It Works

Click in your blade

Click in your blade

Choose the 7mm or 14mm grid, or any slicer insert, and press it into the deck until the locking tabs click.

One smooth press

6 cups of soup mirepoix in under three minutes—zero onion tears

I don't hate cooking, I just hated spending 35 minutes turning onions, carrots, and a mountain of celery into tiny squares before turning the stove on. Did my whole Sunday soup prep right next to the sink in less than three minutes and didn't tear up once with my contacts in. Also, that little charcoal fork claw for flicking stuck onion skins out of the pusher grid deserves an award—one swipe under the faucet and it's spotless.

Way heavier plastic than the viral one that cracked on us

Just unpacked mine on the kitchen table and you can immediately feel the difference in the clear 1.5L tub—thick, solid walls instead of that brittle glassy plastic that spiderwebbed on our old chopper after four uses. Everything came neatly nested with the internal blade caddy, drain basket, hand guard, and all the stainless inserts. Not having loose razor-sharp grids floating around my utensil drawer is huge.

Thunks straight through raw sweet potatoes without straining my wrists

My arthritic wrists used to ache after prepping sheet-pan dinners for the family. Cheap choppers stall out on raw sweet potatoes and butternut squash, so I was nervous, but as long as you cut the potato in half so it sits flat, the leveraged lid gives you enough mechanical push to drop right through in one smooth press. The four rubber feet grip wet granite counters without skating sideways.

Dry restaurant-style pico cubes—didn't mash ripe tomatoes!

I honestly expected it to crush ripe Roma tomatoes into watery salsa mush, so my jaw dropped when neat, dry little cubes fell straight into the tub. Brought 8 cups of cowboy caviar and pico to a neighborhood barbecue and three different people asked how I had the patience to hand-dice everything into identical tiny squares.

Already paid for itself in saved grocery runs

At 50% off, this paid for itself inside two weeks simply because I stopped buying those $6 plastic tubs of pre-chopped fajita veggies and mirepoix at the grocery store. Cut our weeknight prep down from 30 minutes of knife drudgery to 4 minutes flat, so we actually make fresh chopped salads on Wednesdays instead of caving on delivery.

Super sharp 420 blades—just treat them with respect

Serious upgrade over a food processor, which always turns peppers and onions into wet baby food. Only knocking off half a point if I could because you do still have to halve big onions or Russet potatoes with a knife first so they fit inside the outer rim of the dicing grid. Once they fit the grid, though, it slices effortlessly. Watch your fingers when swapping inserts—these blades are legit razor sharp.

Mandoline slicer + hand guard actually feels safe

Regular mandolines scare me to death, so having the slicing insert click right into the top of the 1.5L catch tub with the pronged hand guard is so much cleaner and safer. Did four English cucumbers for cucumber salad in about 45 seconds and every slice stayed inside the container instead of flying across the counter.

Top-rack dishwasher safe and hasn't warped

Our previous chopper warped into a banana shape the very first time my husband put it on the top rack on normal dry. We've run the PrepGrid 14 tub and lid on the top rack (no heated dry, just normal wash) a dozen times now and everything still snaps shut tight and true. Zero clouding on the clear container either.

The inner drain basket is smarter than I realized

Didn't think I'd use the little strainer basket inside the catch tub, and now I leave it in almost every time. You can dice zucchini, bell peppers, or rinsed celery directly into the basket, lift the whole thing out to rinse under the tap, shake off the water, and dump straight into a hot skillet without oil splattering everywhere.

Rock solid on dense carrots and meal-prep potatoes

I prep 5 pounds of diced hash-brown potatoes and stir-fry carrots every Sunday. On cheaper choppers you can literally watch the metal grid bow downward before a blade pops loose. The collar on this Cosari unit doesn't budge at all—just clean, square cuts straight down into the bin.

Frequently Asked Questions

Will it cut raw carrots, potatoes and sweet potatoes without bending the blades?

Yes. Use the 14mm large-dice grid and place the vegetable flat side down. In our test, the 0.6mm hardened 420-J2 blades went through 50 raw root halves with no measurable bend.

Will it squish ripe tomatoes or soft onions?

No. The honed edges cut through tomato skin cleanly instead of bursting it, so ripe Romas come out as dry, square cubes.

Is the catch container dishwasher safe?

The 1.5L BPA-free container is safe on the top rack. It came through 15 dishwasher cycles and a 3-foot drop in our testing without cracking. Skip high-heat sanitize cycles to protect the blades.

Where do all the pieces go when I'm done?

All the blade inserts clip into a storage caddy that nests inside the 1.5L container, so the whole kit fits in a 10.8 × 4.7 × 4.5-inch space.

How hard is it to clean onion skins out of the grid?

Not hard at all. The included 9-tooth cleaning claw fits the pusher grid exactly, and one swipe under the tap clears it in about five seconds.

Does it protect my fingers on the slicing blades?

Yes. It comes with a clip-on safety hand guard with stainless gripping prongs, so your fingers stay away from the slicer, wavy and julienne inserts.
