NutriBullet NBP50100 Food Processor Review

The box holds a stainless chopping blade, a plastic dough blade, a spiralizer disc, a reversible thick slice/shred disc and a reversible thin slice/shred disc, plus the lid with feed chute, the dual-size food pusher, a blade adaptor, a recipe book and a user guide. That is a full prep kit in a machine that weighs 6 lb.

Slicing and shredding

The two reversible discs give thick and thin cuts of both slice and shred, and the wide feed chute swallows whole potatoes, blocks of cheese and several carrots at once. Carrots and cheddar come out in even shreds, cucumbers and mushrooms in clean slices, and Brussels sprouts and potatoes break down fast. Consumer Reports rates slicing and shredding excellent and chopping very good, which matches what the discs are built to do.

The dual-size food pusher

The inner pusher twists out to leave a narrow chute for slim items like carrots and zucchini, and it doubles as a channel for drizzling oil or liquid while the machine runs. The outer pusher has spikes to grip produce. Pull the chute insert out entirely and the full-width feed opens for bulky items.

The spiralizer disc

The disc sits stationary in the bowl while a small circular blade inside it rotates, which is not how most people expect a spiralizer to work. What it delivers is long, uniform curls with very little vegetable wasted, and it is quicker and more consistent than a hand-crank tool. Homes & Gardens called it the feature that stood out, and it is the one most owners would not otherwise buy separately.

Chopping, pureeing and dough

Salsa, pesto, dips, minced garlic and herbs, chopped onion, breadcrumbs, nut butter and oat flour all land in range. Pulsing gives a texture a blender cannot match, so salsa keeps body instead of turning frothy. The plastic dough blade is deliberately soft so it stays gentle on gluten: use LOW only, pulse to cut fat into flour, then run LOW to bring the dough together and add liquid through the narrow chute. Pie crust and other crumbly doughs are the sweet spot.

Living with it day to day

At 7.4 inches long, 11.5 inches wide and 15.75 inches tall, it lifts off the counter and stores on a shelf, and four suction-cup feet hold it steady while it runs. The cord wraps under the base, every attachment is top-rack dishwasher safe, and the base wipes clean. All attachments except one disc store inside the work bowl between uses, in one of two stacking arrangements. Assembly is foolproof thanks to labeled arrows and an interlock that keeps the motor off until the bowl is clicked onto the base and the lid locked.

Buyers on Amazon most often praise performance, ease of use, power, ease of cleaning and compactness, and the large majority of ratings are four or five stars.

The 450-watt motor is modest for a full-size processor, and the machine enforces strict limits to protect it. Never run it continuously for more than one minute, and leave at least a minute between cycles. After ten minutes of cumulative running the thermal cutoff trips, the unit stops and the lights flash three times: unplug it and let it rest 15 minutes.

The liquid ceiling is low. The LIQUID MAX line holds 2 cups, so this is a prep machine, not a soup machine. Overfilling leaks and can damage the bowl and lid. If soup or large-batch puree is the goal, this is the wrong machine.

Grating hard cheese is the weak spot. Shredding cheddar, Swiss or mozzarella works well once the cheese has chilled, but parmesan comes out less fine and less fluffy than from a dedicated grater, and Consumer Reports rates grating only fair. Use cold hard cheese, the thin shred disc or short pulses of the chopping blade. Soft, high-water greens are the other trouble spot: cabbage and lettuce release water and fall apart against the discs, so pulse them with the chopping blade instead.

The pulse button has a noticeable delay before the blades spin. That is a characteristic of the control rather than a fault, and running LOW for a short burst gives the same controlled chop. The machine shakes a little at medium and high speed, though the suction feet keep it planted.

Dough results are inconsistent. Some reviewers end up with a dry crumbly dough, while others get an incredibly light, fluffy, smooth ball, so treat it as a technique-sensitive job that depends on hydration, on using LOW only and on not overfilling. One disc stays out of the bowl when everything is stored. There is no mini-bowl insert, no julienne blade, no whisk attachment and no variable speed dial, only the three fixed settings. The bowl can stain after turmeric, parsley or carrots, which is cosmetic and lifts with a scrub or a baking-soda paste. The warranty runs one year, limited, on motor and parts, which is short for this class of appliance.

Buyers on Amazon are divided on durability and on size: some find it built to last and well proportioned, others find it less sturdy than expected or smaller than they pictured.

The 7-cup figure is nominal. Once the blade and the lid are in place, the usable capacity is lower, so plan on filling it less than the number suggests. The footprint is what makes it easy to live with: at 11.5 inches wide it fits a narrow stretch of counter, and at 6 lb it is light enough to move to a shelf between uses.

Matching the speed to the job is most of the battle. LOW handles kneading, spiralizing, slicing and shredding. HIGH is for fine processing and pureeing, mincing garlic and herbs, pesto, dips, nut butter and milling oats into flour. PULSE gives texture control for nuts, herbs, onions and breadcrumbs; it runs at HIGH speed and must be held down.

Respect the duty cycle: one minute on, one minute off, and after ten minutes of cumulative running, a 15-minute rest. Three flashes mean the thermal cutoff has tripped, not that the machine has failed. Keep an eye on the LIQUID MAX line and add liquid through the narrow chute of the dual-size pusher rather than pouring it into the bowl. Use LOW for dough every time, since HIGH overworks it and makes it tough, and LOW for the discs and the spiralizer.

If the machine will not start, check that the bowl is clicked onto the base and the lid locked with the arrows aligned. If the lid unlocks mid-run, the unit stops and the lights flash. Before the chopping blade goes in the dishwasher, separate it from the blade adaptor or food gets trapped between them, and never use a sanitize cycle, which warps the plastic.
