Vitamix Food Processor on the A3500 blender base

Serious Eats / Grace Kelly

Straight to the Point

The Vitamix Food Processor (which we paired with the A3500 Vitamix blender in our testing) did a great job at all the tasks we threw at it: emulsifying mayonnaise, shredding beets, slicing potatoes, making pie dough, and blending hummus. It was also easy to clean (at least, for a food processor) and didn’t stain. However, if you’re looking for a very responsive food processor, the winners from our previous testing, the Magimix 14-Cup Food Processor and Cuisinart 14-Cup Food Processor, might be better bets.

A good food processor is an integral part of a well-stocked kitchen. These powerful machines can shred, slice, chop, pulverize, and puree, making them incredibly versatile. But they are also bulky, hard to clean, and many people wonder: do I really need one, or can I just use my blender, a grater, and a mandoline, and call it a day?

While we’ve made the argument before about why a food processor deserves a spot in your kitchen, I was curious about an offering from the maker of our favorite blender: the Vitamix Food Processor. This attachment pairs with the brand’s Ascent A-series line of blenders, as well as the Vitamix Venturist V1200, omitting the need for another bulky machine base. But could it blitz, blend, pulse, and puree as well as our favorite food processors?

The Tests

  • Mayonnaise Test: I made mayonnaise in the food processor to see if it could emulsify the mixture. 
  • Slicing Test: I used the small slicing disk to slice three peeled potatoes into 1/4-inch rounds. 
  • Shredding Test: I used the small shred disk to shred three small, peeled beets. Then, I left the shredded beets in the container for 20 minutes before washing it, to see if it stained.  
  • Dough Test: I made an all-butter pie dough to test the processor’s pulsing ability. 
  • Hummus Test: I blended the ingredients for hummus to see how smooth the food processor could get the puree. 
  • Cleaning Test: I hand-washed the food processor’s components after each test, including the slicing and shredding discs.

What We Learned

The Food Processor Was as Good as the Blender Base

The food processor doesn’t come with a motor; instead, you place it on one of the compatible Vitamix blenders from the Ascent series, or the Vitamix Venturist V1200. The “self-detect” motor base on the processor interacts with the blender base to let it know it’s not a blender jar (this limits what the base does, restricting it to on, off, and pulse; there are no speed adjustments).

I tested the food processor with the A3500, which we’ve reviewed before, and found that the base and food processor performed well in tandem. So, if you like your A-series blender base and find it easy and intuitive to use, chances are you will like using it with the food processor attachment. However, this feature is a double edged sword; if you already have one of the A-series blenders, you’re in luck and can use the food processor with it. If you don’t, you’d have to invest in a blender as well as the food processor kit—and together, it adds up; the A3500 blender plus the food processor comes out to $837. In contrast, our winners for food processors, the Magimix 14-Cup Food Processor and Cuisinart 14-Cup Food Processor, are $400 and $300, respectively. So it really depends on whether or not you already have a compatible blender to make the food processor worthwhile financially.

It Was Surprisingly Good at Emulsifying

Food processors are notorious for struggling to produce nicely emulsified mayonnaise, but the Vitamix food processor surprised us with great results.

I’m a big fan of homemade mayonnaise; pair it with some French fries, and I’m butter in your hands. But I’ve always turned to my immersion blender to make it—never my food processor (which are notorious for blending too fast and failing to emulsify the egg and oil mixture). So, I set out to see if the Vitamix food processor could turn me to the dark side. I made a batch of mayonnaise and poured oil into the feed tube pusher, which has a hole in the center for the express purpose of letting liquids slowly drizzle in, and found it did an excellent job at emulsifying the ingredients (and this was a recipe that used four egg yolks, making it ultra-prone to splitting). I was impressed with the results, and immediately set out to make French fries to dip in my mayo.

The Disks Were Easy to Use (and Performed Mostly Well)

When it came time to test the food processor’s disks, assembling them was as easy as removing the all-purpose blade and putting a disc in its place. Snap on the lid on and voila, it was ready to process. The discs did a good job at slicing potatoes and shredding beets, though I had a few quibbles: the first was that the tube where you put your ingredients was a little small, so I had to trim the edges of the potatoes and halve the beets to get them to pass through (though, to be fair, the opening is actually larger than in my Cuisinart food processor). The second was that while a majority of the potatoes were consistent in thickness (about 1/4-inch), towards the end of the slicing process the machine shot out paper thin wafers instead of the usual 1/4-inch slice. A big deal? No—but I noticed. There were also a few chunks of beet left on the top of the shredding disc when I took the lid off. 

It Wasn’t as Responsive as it Could Be

When I pulsed the processor while making pie dough, I noticed the blade spun around one or two times more after I released the pulse button. While this didn’t have any tangible effects on the resulting dough (I was a bit nervous it would overwork it and heat up the butter), a better food processor would be more responsive and stop its blade almost immediately. 

It Was (Mostly) Easy to Set Up and Clean

Like all Vitamix blenders, there are no complicated locking mechanisms involved in putting the blenders (or in this case, food processor) on the machine base; you simply place it on the four prongs sticking up. The rest of the food processor was also easy to assemble (it was pretty standard), though I did have some trouble locking and removing the lid; instead of a sliding lock feature like I’m used to on my Cuisinart, there are two tabs that snap onto the base when you push the lid down, and snap off when you remove it. A few times I really struggled and wound up lifting the whole thing off the blender base by accident. On the bright side, the food processor was surprisingly easy to clean; it also didn’t stain after grating beets, which was impressive.

The Verdict

VitamixFoodProcessorAttachment

If you have a Vitamix A-series or Venturist blender, don’t currently own a food processor, and don’t want to spend a ton of money, the Vitamix Food Processor is a solid buy that will perform well with most kitchen tasks. Plus, it’s good for small kitchens, since you can use it with your blender base. However, if you’re frequently making pie or bread dough with your food processor, you might want to invest in a more precise, responsive machine.

Is the Vitamix food processor worth it?

If you’re short on space and already have a Vitamix A-series blender (and don’t have a food processor), this food processor attachment is a solid pick. However, it’s not quite as responsive as our favorite food processors.
