Kitchen Gadgets That Are a Total Waste of Money

The kitchen gadget industry thrives on solving problems you do not have. Every year, millions of single-purpose tools get purchased, used once or twice, and banished to the back of a drawer where they gather dust alongside that garlic press you bought in 2019.

Some of these gadgets are genuinely useless. Others solve a real problem but do it worse than the knife and cutting board already sitting on your counter. A few are outright scams that look clever in a 30-second video but fall apart under actual kitchen conditions.

Here is an honest accounting of popular kitchen gadgets that are not worth your money, your counter space, or your drawer real estate — along with what to use instead.

The Hall of Shame

Avocado Slicers

The three-in-one avocado tool — with a blade to cut, a pick to remove the pit, and a fan-shaped scooper — appears in nearly every “must-have kitchen gadgets” list. In practice, it does every one of those jobs worse than a regular knife and spoon.

The blade is too dull to cut cleanly through avocado skin, often crushing the flesh. The pit remover requires you to stab into the avocado with force, which is more dangerous than the tap-and-twist method with a chef knife. The scooper tears the flesh instead of releasing it cleanly.

Use instead: A chef knife to halve the avocado, a quick tap of the blade into the pit and twist to remove it, and a large spoon to scoop the flesh. Faster, cleaner, no extra tool to wash.

Electric Can Openers

Electric can openers were useful when manual can openers were poorly designed and hard to operate. Modern manual can openers — particularly smooth-edge models like the OXO Good Grips or Kuhn Rikon — open cans faster, more quietly, and with a safer finished edge than most electric models.

Electric can openers are also bulky, require counter space and a power outlet, and break frequently. The gears strip, the cutting wheel dulls, and the magnet that holds the lid weakens over time. When an electric can opener fails mid-can, you still need a manual opener as backup.

Use instead: A smooth-edge manual can opener ($10-15). It stores in a drawer, never needs a power outlet, and the smooth edge means no sharp lid to cut yourself on.

Banana Slicers

This yellow plastic tool cuts a banana into uniform slices in one motion. Sounds efficient until you realize that a butter knife does the same thing in about three seconds, a banana is one of the softest foods that exists, and the slicer only works on bananas of one specific diameter.

This is the canonical example of a solution looking for a problem.

Use instead: Any knife. Or your hands. Bananas break cleanly at natural segment points if you just press gently.

Egg Separators

Ceramic, silicone, or metal gadgets designed to separate egg yolks from whites by catching the yolk while the white drains through. They work, but they are no faster than the shell-to-shell transfer method that every cook already knows, and they are one more item to wash.

Use instead: Crack the egg and pass the yolk back and forth between the two shell halves, letting the white drain into a bowl below. Takes five seconds, creates no dishes, and works perfectly once you have done it twice.

Herb Scissors (5-Blade)

Five parallel blades that chop herbs in multiple cuts simultaneously. The marketing suggests this saves time on mincing herbs. The reality: the blades clog with herb matter after two or three cuts, the cuts are inconsistent because the blades cannot be individually sharpened, and cleaning five parallel blades packed with crushed basil takes longer than mincing herbs by hand.

Use instead: A sharp chef knife and the rock-chop technique. Or kitchen shears for snipping herbs directly over a dish. If you prep herbs in volume, a good food processor does the job in seconds.

Quesadilla Makers

A dedicated electric appliance that heats two flat surfaces to toast a quesadilla. It does exactly one thing that a skillet already does, takes up significant storage space, and produces worse results because you cannot control the heat or press the quesadilla flat.

Use instead: A skillet over medium heat with a second pan or plate pressing down on the quesadilla. Better browning, better cheese melt, better control, zero additional appliance to store or clean.

Garlic Peelers (Silicone Tube)

Roll a garlic clove inside a silicone tube, and the friction removes the skin. This sounds clever and technically works, but the crush-with-the-flat-of-a-knife method is faster, also loosens the skin instantly, and does not require buying or storing another single-purpose tool.

Use instead: Place the garlic clove on the cutting board, lay the flat of your chef knife over it, and press down firmly with the heel of your hand. The skin splits and slides off in one motion. Two seconds, no gadgets.

Electric Knife Sharpeners Under $30

Cheap pull-through electric sharpeners with carbide or ceramic V-shaped slots. They aggressively remove metal at a fixed angle that may not match your knife, leave a rough, toothy edge that dulls quickly, and can overheat the thin edge of the blade, affecting the steel’s temper.

The worst part: people use these on expensive knives and then wonder why their $150 chef knife performs like a butter knife after six months.

Use instead: A ceramic honing rod for regular maintenance ($15-25) and a combination whetstone (1000/6000 grit, $25-40) for periodic sharpening. We have a complete guide to sharpening knives at home if you want to learn the technique.

Spiralizers (Dedicated Countertop Models)

The spiralizer craze peaked around 2018-2020 and left a trail of bulky, hard-to-clean countertop spiralizers in kitchens everywhere. A dedicated spiralizer takes up as much space as a toaster and does one thing: make vegetable noodles.

If you eat spiralized vegetables weekly, a countertop model makes sense. For everyone else, a $10 handheld julienne peeler or a mandoline with a julienne attachment does the same job, stores in a drawer, and cleans in seconds.

Use instead: A handheld julienne peeler for occasional use, or a mandoline with a julienne blade for frequent use. If you already own a food processor, check if it has a spiralizer attachment — many do.

Gadgets That SEEM Wasteful but Actually Earn Their Keep

Not everything that looks like a unitasker is worthless. A few gadgets that get unfairly lumped into the “waste of money” category actually justify their existence:

Instant-Read Thermometer ($15-25)

The single most useful kitchen tool after your knife. Removes all guesswork from cooking proteins, baking bread, tempering chocolate, and checking oil temperature. A good kitchen thermometer pays for itself the first time it saves you from an overcooked steak or undercooked chicken.

Microplane Grater ($12-15)

Looks like a unitasker for zesting citrus, but it also finely grates hard cheese, fresh ginger, garlic, nutmeg, cinnamon sticks, and chocolate. The Microplane is a genuine multi-tasker disguised as a specialty tool. Our Microplane and grater guide covers the options.

Kitchen Scale ($15-25)

Baking by weight instead of volume is more accurate and produces more consistent results. A kitchen scale also helps with portion control, recipe scaling, and measuring ingredients that are awkward to cup-measure (like honey or peanut butter). This is a tool that improves everything you cook once you start using it.

Rice Cooker ($30-80)

Sounds like a unitasker, but a rice cooker makes perfect rice every time with zero attention, freeing up a burner and your focus for other dishes. Higher-end fuzzy logic models also handle steel-cut oats, quinoa, steamed vegetables, and even cake. Our rice cooker guide covers the full range.

The “Will I Actually Use This?” Test

Before buying any kitchen gadget, ask yourself these three questions:

1. Does this do something a knife, pan, or basic utensil cannot do? If a knife and cutting board can accomplish the same task in roughly the same time, the gadget is redundant. A food processor passes this test because it processes volumes of food in seconds. An avocado slicer fails because a knife does it better.

2. Will I use this at least once a week? Weekly use justifies drawer space. Monthly use does not. A citrus juicer makes sense if you drink fresh juice regularly. A melon baller does not make sense unless you run a catering company.

3. Can I store it easily? A Microplane slides into a drawer. A countertop spiralizer requires dedicated cabinet space. Storage difficulty correlates directly with how quickly a gadget gets abandoned. If you have to move other things to access it, you will stop using it.

If a gadget fails any of these three tests, skip it. Your kitchen will be cleaner, more organized, and more functional with fewer, better tools.

What to Buy Instead

The most useful kitchen is built on versatile fundamentals, not specialized gadgets. Here is the core toolkit that handles virtually every home cooking task:

• One excellent chef knife — the single most important tool. See our guide to knives under $200
• One paring knife — for detail work, peeling, and small cuts
• One bread knife — serrated, for bread, tomatoes, and anything with a tough skin
• A sturdy cutting board — wood or plastic, large enough to work on comfortably. Our cutting board guide covers the options
• Cast iron skillet — see our cookware comparison
• A heavy-bottomed pot — for soups, stews, boiling, and sauces
• Instant-read thermometer — eliminates guesswork on every protein
• Kitchen scale — transforms baking consistency
• Wooden spoon and silicone spatula — your two primary stirring and scraping tools
• Sheet pan and wire rack — for roasting, baking, and cooling

That list covers 95% of home cooking. Everything beyond it is either a luxury (stand mixer, food processor) or a specialty tool for specific cuisines and techniques. Buy those luxury items only when you find yourself repeatedly wishing you had one — not because a marketing video made it look essential.

The best kitchen is not the one with the most gadgets. It is the one where every tool gets used regularly and nothing hides forgotten in the back of a drawer.
