What is a food processor?

A food processor is a versatile kitchen appliance designed to save you time and energy when prepping meals. Each unit has a base, a plastic mixing bowl, removable blades and a lid, and they also generally come with variable speeds and a pulse function. 

You can chop and shred vegetables and even mix dough in a food processor, but they can really do just about anything related to food preparation. They slice, dice, chop, shred, grate, zest, mash, puree, mix, knead, grind and emulsify. Add a blender and you can chop nuts and spices, crush ice and blend cooled soups.

How much do they cost?

In our latest food processor reviews, models range between $49 and $1399, but we've found price isn't always an indicator of quality – some models we've recommended cost less than $300. If you're in the market for something smaller, mini food processors cost between $15 and $195.

How noisy are food processors?

There's no denying that a food processor is a noisy appliance. If you're looking for one that's quiet, it's unlikely you'll find a model you're completely happy with. We've taken noise measurements of the food processors we've tested and found that they range between 68dB and 92dB. By comparison, a typical conversation is carried out at roughly 60dB, while city traffic is measured at around 80dB. 

We consider noise readings over 70dB to be noisy and readings over 80dB to be very noisy. The quietest models we've tested still require you to raise your voice if you're having a conversation, but listening to the loudest models is like hearing a motorcycle only eight metres away.

Can you use a blender as a food processor?

These appliances are best suited to different functions. A blender is ideal for smoothies, soups and milkshakes, while a food processor is ideal for the various steps of preparing a meal, like chopping, dicing and mixing. Food processors have many attachments and manufacturers are starting to include a blending jug attachment with some models. So which one do you need?

A standalone food processor is a good choice if you have limited bench space or you already have a blender. Otherwise you might want to consider a combination food processor and blender, but they can be bulkier and hard to store.

You should also have a think about what you'll be using your food processor for. If you're an avid cook and generally prepare larger quantities of food, then one of the larger processors with all the bells and whistles will be up your alley. To get the most use out of it, these stylish and often bulky models can become a permanent fixture on your kitchen bench (but storage for all the attachments is a must).

What is a mini food processor?

If you'd only use a food processor occasionally or for smaller quantities like curries, chopped nuts, breadcrumbs and pesto, then a mini food processor that can be quickly pulled out of the cupboard is all you need. They're usually up to 1 litre in capacity, and being compact and lightweight makes them easy to store and clean.

Unlike traditional full-size food processors, mini processors don't generally have a large chute or selection of blades for tasks like shredding and slicing, which means they're unable to slice and grate. You can also use many stick blenders with a processing bowl.

Key features to look for

Storage for all the extra bits and pieces

An internal storage drawer or separate storage box keeps all the attachments together, which is a good way to protect the blades (and your fingers). Some models aren't big enough to store all the blades and attachments included with the appliance, while other containers are quite large and bulky and can take up a considerable amount of space in your cupboard.

Bowl size

The size of the food processor bowl varies from model to model, so think about what you'll be using it for and the amount of food you'll need to process. A mini processor bowl that sits inside the main food processor bowl is great for working with small quantities, making pesto and mayonnaise, and grinding nuts. A separate grinder unit can do much the same thing.

Sealed bowl

Look for a sealed bowl (i.e. one with no hole in the middle that the spindle goes into) to avoid mess and ease of pouring out the load.


A pulse function gives short bursts of power, which helps to distribute the load more evenly and create an even consistency, especially when blending smaller amounts. It can be a button or a pulse dial but we think a button is easier to use.

Processing blade

The processing blade should sit as low as possible to the bowl. This allows for food to be mixed properly and not get stuck under the blade.

Reversible blade

A reversible blade has a grating blade on one side and a slicing blade on the other – it's useful as it cuts down the number of separate blades you need to store.

Slicing/grating blades

Depending on the versatility of the food processor, many can come with a range of attachments (sometimes optional extras) that can slice or grate to various thicknesses from fine or julienne slicing blades to thick slices of cheese.

Chute sizes and double feed chutes

Different chute sizes are handy to allow for various foods to be easily pushed through with minimal cutting required. Some models come with a double feed chute – this is a standard chute with a smaller chute insert that allows for smaller or thinner foods to be guided into the food processor for better control when slicing or shredding.

Rubber feet

Rubber feet on the motor unit can help keep it stable while the machine is in use.

Chipping blade

You'll need this if you want to make chips or vegetable strips.

Beater and whisk disc attachments

You'll need these if you want to whip cream or beat egg whites.

Dough blade

Usually plastic, this is handy if you want to whip up some dough.


A number of models come with a citrus juicer. Some come with a press juice extractor for juicing other types of fruit and vegetables too.

Maximum capacity disc

Not many food processors come with this attachment, but if you're planning to use your food processor to make liquids like almond milk, then this attachment is essential. It changes the force in the processor bowl to push any liquid that rises to the top back into the bowl. With this attachment you can make the most of the maximum liquid capacity while avoiding liquid splattering out of the processor.

Blender attachment

Some food processors come with a blender attachment, but if you already have a separate blender, it's not a must-have.

Integrated scales

These are nice to have when adding ingredients. It's advisable to leave the food processor in one spot on the bench and minimise movement to prevent damaging the scales.

Mixing bowls and patisserie bowls

These can be larger than the food processor bowl and difficult to find storage for, but they're useful for mixing cake batters, doughs and pastries.

Using a food processor to reduce waste

A food processor can help to reduce the amount of processed food that you buy, which can reduce the amount of packaging you bring into the home. It can also help to reduce your food waste – here are some useful tips and ideas.

  • Stale bread can be turned into breadcrumbs, then stored in the freezer.
  • Vegetables like carrots, potatoes, onions and celery can be sliced with the slicer attachment, then blanched and frozen.
  • Herbs can be processed in a mini processor with a little oil and placed into small containers or ice cube trays and frozen.
  • Make your own pesto with any soft leaf herb – parsley is great with a bit of lemon, olive oil and garlic. You can even add any type of nut to give it a creamy texture. Store in a jar in the fridge for up to a week and drizzle on roasted vegetables, fish, chicken and any meat, or use in a salad dressing.
  • Sliced or shredded vegies can be made into pickles. This is a great way to preserve cabbage, carrots, eggplant, zucchini and cucumbers.
  • Finely chop vegetable offcuts to make vegie patties or to add to a bolognaise.
  • Leftover cuts of cheese and vegetables can be grated using the shredding attachment and shaped into vegie fritters to pan-fry.

Cleaning a food processor

Many manufacturers state the bowls and accessories are dishwasher safe, usually on the top shelf and on a lower temperature cycle. However, the dishwasher can cloud the surface of your food processor bowls and we recommend against putting any parts in the dishwasher. 

Instead, we suggest using a couple of drops of detergent with a bit of water and pulsing it through the food processor and leaving it to air dry.
