What Can You Use a Food Processor For?

Every task a food processor does comes down to one of five parts. Match the job to the part and the rest is technique.

The S-blade for chopping, pureeing and mixing

The metal multipurpose blade sitting low in the bowl handles chopping, mincing, pureeing, emulsifying and mixing. It also grinds meat, nuts and grains, and cuts butter into flour for pastry. Most owners use this blade for the large majority of their jobs.

The shredding disc for cheese and vegetables

A shredding or grating disc turns out cheese, potatoes for latkes and hash browns, carrots, cabbage for coleslaw, zucchini, broccoli stalks, chocolate and Brussels sprouts. The disc cuts the food as it passes down the feed tube, so the result is even and fast.

The slicing disc for thin, uniform slices

A slicing disc, often reversible or adjustable for thickness, gives you potatoes for gratin and chips, cucumbers for pickles, radishes, apples, pepperoni and salami, shaved sprouts and packed greens. Feed orientation matters here: how you stand an item in the tube decides how it comes out.

The dough blade for pastry and bread

A plastic, blunt dough blade, or the S-blade on machines without one, mixes pie and pastry dough, pasta dough, pizza dough, bread dough, biscuits, scones and cookie dough. The blunt edge folds and stretches rather than cuts, which is what gluten needs.

The dicing kit, on some models only

A dicing kit produces uniform cubes, and only machines fitted with one can do it. Without a kit, a food processor gives a coarse chop, not a precise dice, and dicing is still best done by hand.

The interchangeable discs and the feed tube in the lid are what make a machine a food processor rather than a chopper. A chopper does the S-blade jobs only.

Chopping is the job most owners reach for first, and the one most often done badly. Onions, garlic, mirepoix, nuts, herbs in quantity, breadcrumbs, cauliflower rice, oat and nut flour and energy-ball mixtures all come out well when you work in short bursts.

Cut the food into ½ to 1 inch pieces first, and fill the bowl no more than half full. Then pulse about one second at a time: 10 to 20 quick pulses gives you a chopped onion. Scrape down the sides between pulses so the pieces at the top come back under the blade.

Pulsing beats running because continuous running pins the food against the bowl walls through centrifugal force, and the blade spins in a pocket of its own making. The result is uneven, with paste at the bottom and whole chunks at the top.

Two limits are worth knowing before you start. A food processor gives a coarse chop, not a precise dice, so anything that needs clean cubes is knife work. And in a full-size bowl, a handful of nuts or a single onion just rattles around the wide base; a mini processor or a knife handles small quantities better.

Slicing and shredding are where a food processor saves the most time, because the discs do in seconds what a box grater does in minutes. Grated cheese, potatoes for latkes and hash browns, carrots, cabbage for coleslaw, zucchini, broccoli stalks and chocolate all go quickly. So do sliced potatoes for gratin and chips, cucumbers, radishes, apples, cured meats, shaved sprouts and packed greens.

Use the right feed tube

The large tube takes whole potatoes, onion halves and cabbage wedges. The small tube takes carrots, zucchini and celery, which would otherwise wobble. Trim items to fit the tube, apply steady pressure with the pusher, and never use your fingers.

Chill what smears and warm what crumbles

Shred cold food. Chill soft cheese before shredding it, and bring hard cheese such as Parmesan to room temperature so it crumbles cleanly instead of shattering. Pack leafy greens tightly and stand them upright in the tube so the disc catches them evenly.

Spray the parts before you start

A light coat of vegetable oil spray on the feed tube, the disc and the bowl before shredding stops cheese and sticky vegetables from gumming up the disc. It also makes the wash-up far quicker, because cheese fat sticks to the disc hub and the lid crevices, which is the recurring complaint about the food processor.

One limit has no workaround: soft cheese does not shred in any food processor, because the disc smears it instead of cutting it.

The S-blade makes hummus, pesto, salsa, dips, dressings, mayonnaise, aioli, hollandaise, nut butter, baby food, tomato sauce and sorbet from frozen fruit. Fill the bowl no more than two-thirds full for a puree, run on high for 30 seconds to a minute, and scrape down the sides once or twice along the way.

For an emulsion, drizzle the oil through the feed tube while the machine runs, so it goes in slowly enough to bind. Order matters for sauces: process the hard ingredients first, such as nuts and garlic, scrape the bowl, then add the soft ingredients and the oil.

For sorbet, process 3 to 4 cups of frozen fruit on low, then freeze the result for 1 to 2 hours.

Why the texture stays coarse

The wide bowl and flat blade never create the vortex a blender jar does, so the puree stays coarser and less even than a blender's. For a chunky dip, spread or dressing, that is exactly the point. For a silky result, it is not.

Keep the liquid low

The bowl seals at the lid and around the blade spindle, so thin liquid can work its way under the blade and onto the base. Keep liquid to about a quarter to a third of the bowl, or to the bowl's max line if it has one.

Never process hot food

Heat and steam build under the locked lid, and processing hot liquid is the most common cause of serious burns from a food processor. Let the food cool first, every time.

A food processor makes pie and pastry dough, pizza dough, pasta dough, bread dough, biscuits, scones, cookie dough and cake batter, and it cuts butter into flour faster and more evenly than your fingertips can.

Use the dough blade, or the S-blade, and run the machine on low. Bread dough is kneaded in 1 to 3 minutes. Pizza dough comes together in seconds, roughly 45 seconds in the machine against about 10 minutes by hand. Pie crust is a matter of quick pulses plus ice water, stopped as soon as the dough holds together.

Use cold or frozen butter for pie dough, so the heat from the spinning blade does not melt it before the flour coats it.

Two limits apply. High-hydration doughs can overload the motor, so keep wet doughs to the recipes the machine is built for. And a food processor is not a stand mixer: it mixes and kneads dough, but it does not whip cream or beat egg whites to the volume a mixer does.

Most of the disappointment with a food processor comes from asking it to do a blender's job or a knife's job.

• Thin liquids, smoothies, juice and large batches of soup. The bowl is not watertight and the puree is coarse. A processor-blender combo is the exception, because it adds a sealed blender jar.
• Mashing cooked white potatoes. The blade ruptures the cells and releases starch, and the potatoes turn gluey.
• Hot food and hot liquid. The texture turns gummy, and the steam under the locked lid is a burn risk.
• Fully frozen meat and rock-hard frozen items. They damage the blade and the plastic. Partially frozen meat is fine, and actually easier to slice cleanly. Do not process ice unless the model is rated for it.
• Whole spices and coffee beans. The grind comes out coarse, and hard spices scratch and cloud the bowl.
• Bones, and an overloaded bowl. Both strain the motor and the blade.
• Citrus zest on its own. Limonene in the peel clouds plastic, so combine zest with other ingredients instead.
• A precise dice. Without a dicing kit you get a coarse chop.
• Small quantities in a big bowl. They rattle around instead of meeting the blade; use a mini processor or a knife.
• Wet, sticky, staining foods. Turmeric and carrot stain the bowl. Rub it with oil afterwards, and soak a turmeric-stained bowl in warm soapy water for 30 minutes.

These are the numbers that decide whether a job comes out right.

• Cut food to ½ to 1 inch before processing.
• Fill the bowl no more than half full for chopping and no more than two-thirds full for puree.
• Keep liquid to a quarter to a third of the bowl, or to the max line.
• Pulse about one second at a time for chopping; run continuous high for 30 seconds to a minute for a puree.
• Use low speed for doughs and batters, and high for most chopping and all slicing and shredding.
• Underprocess. You can always pulse more, never less, and cauliflower rice goes gluey once it is overworked.
• Scrape down the sides between pulses.
• Seat the bowl on the base before filling it, or the blade will not sit flush.
• Wash and dry produce first, so you are not adding water to the bowl.
• Keep your hand away from the blade, and do not soak it loose in a sudsy sink where you cannot see it.
• Store the blade inside the bowl between uses.
• Process dry jobs before wet ones, and rinse the parts immediately, so you wash them once.

One rule of thumb settles most of it: if you eat it with a fork or a spoon, it belongs in the food processor; if you drink it or pour it, the blender; if you spread it, either works but the texture differs.

A mini chopper does the S-blade jobs only, with no slicing or shredding discs. A blender is the answer for thin liquids, silky purees and large batches of soup. A combo machine, one motor base with a blender jar and a processor bowl, suits someone who wants a single appliance for both.

The reason food processors gather dust is setup and cleanup, not capability. Washing the bowl, the lid, the blade and the disc after a five-second job is a real cost, and for a quick meal for one, a knife still wins.

Owners tend to fall into two groups. The batch cook shreds cheese, makes dips, hummus and pesto, and kneads dough every week, and the machine earns its counter space. The weeknight cook finds that the washing outweighs the time saved, and the machine stays in the cupboard.

There is a middle ground: a mini processor for small jobs, or a full-size machine kept out on the counter and used in batches rather than for single tasks. A few habits tip the balance. Spray the disc and bowl with oil before shredding. Process dry jobs before wet ones. Rinse the parts the moment you finish. Store the blade in the bowl so assembly is one step.

If you slice, shred, knead or want chunky texture regularly, a food processor earns its place. If it is only small chopping, it does not.

A heated all-in-one processor is a food processor bowl on a heated base, with guided recipes on a screen. On top of every prep job above, it can saute, steam, simmer, stir and slow-cook, and it weighs ingredients as it goes.

It is the same machine with the cooking step added, not a different category. The chopping, slicing, shredding, pureeing and kneading work exactly as they do on a standard processor; the cooking functions are extra, and they mean one bowl goes from raw ingredients to a finished dish without a second pot.
