Non-Toxic Rice Cookers: Which Pots Are Uncoated?

The best non-toxic rice cookers cook in an uncoated stainless steel pot, so the rice never sits on a nonstick coating. For one to three cups of dry rice, that is Aroma’s Select Stainless ARC-753; for two to seven, the ARC-757SG. The Buffalo Classic adds brown-rice and porridge programs to a clad stainless pot. If you already own an Instant Pot Duo, its 18/8 stainless pot and rice program may make a new appliance unnecessary.

Check the surface that touches the rice, not the body or the outside of the pot: Cuckoo’s Xwall pot, for one, is stainless outside and nonstick inside. A coated pot in good condition is no reason to replace a cooker that works, and when one wears through, Zojirushi, Cuckoo and Instant sell the pot on its own.

Uncoated Stainless Steel Rice Cookers Compared

Each cooker below cooks in a stainless steel pot with no nonstick coating, by its maker’s description. Capacities use the rice-measuring cup that comes in the box; Aroma’s holds 180 ml, three-quarters of a US cup.

Aroma Select Stainless ARC-753 and ARC-757SG

The ARC-753 is the small one: one to three cups of dry white rice, up to six cups cooked, in a 304 stainless pot under a glass lid. One switch starts it, and it drops to Warm on its own when the water is gone. It draws 300 W and carries a one-year warranty. The black ARC-753SGB was $35.45 on Amazon (Oct 2026), and Aroma lists the ARC-753 at $45.

The ARC-757SG puts the same pot design in a 14-cup (cooked) size. Its manual asks for at least two cups of dry rice and allows up to seven, so it suits regular large batches rather than a cup at a time. It draws 500 W and was $55 at Aroma and on Amazon (Oct 2026).

Aroma lists spare stainless pots for both sizes, at $15 and $20, but both were out of stock at Aroma in September and again in October 2026; Aroma says many restocks take six to eight weeks. Both product pages carry California’s short Prop 65 warning, “Cancer and Reproductive Harm,” which names no chemical or part, a wording California’s rules still allow on products made and labeled before 2028. Ask Aroma if that matters to you.

Buffalo Classic KWBSC10-II

The Buffalo is the small uncoated cooker with programs: white rice, brown rice, porridge and soup, plus Keep Warm. Buffalo describes the 1-liter pot as patented clad stainless steel that “does not contain an unhealthy chemical coating,” and it warrants the inner pot for three years and the outer pot for one. It was $139 on Amazon and $149 at Buffalo (Oct 2026).

Buffalo sells it as a five-cup cooker without saying whether that means dry or cooked rice, so compare it with the Aroma ARC-753 by pot size: 1 liter against the ARC-753’s 1.2 quarts, about 1.1 liters.

Instant Pot Duo 6QT

The Duo 6QT’s standard pot is 18/8 stainless with a tri-ply bottom, and rice is one of its seven cooking functions. It is a 1,000 W pressure cooker, so rice follows pressure-cooking rules: use the manual’s grain chart and fill lines. If yours works, start there. New, it was $109.99 at Instant and on Amazon (Oct 2026).

What Touches the Rice: Steel, Ceramic, PTFE, Clay or Glass

A rice cooker cooks by boiling. Aroma describes the cycle: a heated plate brings the water in the pot to a rolling boil until the grain absorbs it, and a sensor touching the pot switches the cooker to Keep Warm once the temperature climbs past boiling; Aroma puts Keep Warm at 158°F to 194°F as a general guide. The pot’s surface, and the lid above it, are in contact with hot rice and steam for the whole cook and every hour on Warm.

PTFE, the nonstick sold as Teflon, is the coating to understand first, and Zojirushi says its products use it. The FDA authorizes PFAS-based nonstick coatings for pots and pans, citing studies that show negligible amounts of PFAS can migrate from the coating to food. The heat risk sits far above boiling: Singapore’s food agency puts the start of PTFE fumes past 260°C (500°F) and the coating’s breakdown past 350°C (662°F). Its other warning is about damage, since a scratched or worn coating can shed PFAS and micro- and nanoplastics into food, and the agency advises replacing nonstick cookware once the coating visibly deteriorates.

Ceramic nonstick is a coating too, not a solid ceramic pot. Our Place’s rice cooker uses one and says it is made without PFAS, PTFE, PFOA, lead or cadmium; Aroma’s ARC-914SBD and Instant’s spare aluminum pot have ceramic-coated interiors without a comparable list. Read the labels closely. Zojirushi’s FAQ says all of its rice cookers’ nonstick pans are PFOA-free, so a PFOA-free pan can still be a PTFE pan. The same labels show up on air fryer baskets, and our non-toxic air fryer guide sorts those by what the food sits on.

Clay is the other uncoated route. VitaClay’s rice cookers use an unglazed Zisha clay pot; VitaClay says the cooker is “FDA, CA Prop 65 and RoHS laboratory tested” without publishing results, and that the pot needs liquid in it to cook. The FDA’s lead warnings for pottery concern glazes and decorations, which can leach lead into food when the pottery isn’t made properly, and Health Canada advises against cooking in glazed ceramic bought outside Canada or labeled with a lead or cadmium warning. Our non-toxic slow cooker guide covers VitaClay and glazed crocks in more detail.

Among these cookers, glass shows up only as the lid. Aroma’s Select Stainless cookers have glass lids, and Elite Gourmet’s ERC2010B has a vented tempered-glass lid over its stainless pot. None of the cookers in the table cooks in a glass pot.

The parts in the steam vary by model. Zojirushi says every surface that touches food on the NS-TPC10 is free of PFAS and BPA. Pressure cookers add a gasket: Instant’s sealing ring is food-safe silicone, and Cuckoo’s seal is rubber packing. Aroma and Buffalo don’t describe the materials of the steam vent, so ask them if that part matters to you.

Stainless steel has its own caveats. The 304 grade in most of these pots is 18/8, about 8% nickel, and Health Canada advises people allergic to nickel not to use cookware that contains it; our 18/8 vs 18/10 guide explains what the grade numbers say. Wash a new pot before the first use: Aroma’s manuals say to wash the inner pot and accessories in warm, soapy water, then rinse and dry them thoroughly.

Dry Cups, Cooked Cups and Quarts

“Six cups” can mean six cups of cooked rice or six of dry, a whole size class apart. Rice cookers measure in the cup that comes with them, and on the Aroma models the cooked maximum is twice the dry one. The Aroma ARC-753 takes one to three cups of dry rice, the ARC-757SG two to seven. An Instant Pot is measured differently again: six quarts is the size of the pot.

The minimum matters as much as the maximum. A cooker bought for guests can mean cooking at least two cups in the ARC-757SG on ordinary nights. Aroma’s sizing advice puts 3- and 6-cup (cooked) models with people cooking for themselves, 8-cup models with households of two or three, and 12-cup models with four or five. Brown rice takes more water than white, and each manual has its own chart for it, so check the brown-rice limits before relying on a white-rice maximum.

Fuzzy Logic or a Simple Switch

A one-switch cooker such as the Aroma Select Stainless has no program to choose: it heats until the water is gone, and the rise in temperature flips it to Warm. A fuzzy-logic cooker adjusts as it goes. Our Place describes sensors in the lid and base that monitor steam and heat and change the temperature in real time; Zojirushi says its Neuro Fuzzy models make fine adjustments to temperature and heating time; Aroma’s Sensor Logic cookers soak the grain at a lower temperature, cook at around boiling and finish with a burst of heat.

The catch is the pot. Zojirushi’s NS-ZCC10 and NS-TPC10, Our Place’s rice cooker and Aroma’s ARC-914SBD all pair their programs with nonstick or ceramic-coated pans. Among the uncoated cookers here, the Buffalo and the Instant Pot have programs. If you mostly cook white rice, a switch does the job; if brown rice or porridge is a daily staple, look at the cookers with those settings.

Keep the Rice Cooker You Own

Wear on a coated pot is a reason to replace the pot, not the cooker. Zojirushi tells owners that small scratches won’t affect the rice as long as the pan isn’t peeling, and that a peeling pan should be replaced; Aroma says discoloration and scratches on its inner pots are usually cosmetic, though its warranty doesn’t cover cosmetic damage. Spare pots for popular models:

Rice cooker you may own	Pot it ships with	Replacement pot (Oct 2026)
Zojirushi NS-ZCC10	Nonstick pan	Pan B201, $69.85 (Zojirushi)
Zojirushi NS-TPC10	Nonstick pan sold as free of PFAS, including PTFE	Pan B688, $86.60 (Zojirushi)
Cuckoo CRP-PHTR0609F	Xwall nonstick pot	Stainless CRI-HAC0610N, $99.99, or Xwall pot, $89.99 (Cuckoo)
Instant Pot Duo 6QT	18/8 stainless pot	Stainless pot, $40.33 (Amazon); $39.99 at Instant, sold out
Aroma ARC-753 / ARC-757SG	304 stainless pot	$15 / $20 (Aroma), both out of stock

Two of those swaps change the surface. Owners of Cuckoo’s CRP-PHTR0609F, which ships with the Xwall nonstick pot, can move to the stainless CRI-HAC0610N, which Cuckoo lists for that model and the CRP-OHTR0609F; it has 304 stainless inside, an aluminum core and 439 stainless outside. For an Instant Pot, the six-quart Instant Pot stainless inner pot on Amazon replaces a damaged steel pot or Instant’s ceramic-coated spare; Instant says it fits most six-quart models but not the Duo Evo Plus. Aroma says most of its models sold with a nonstick pot can’t take a stainless one, so ask with your model number before ordering.

The smaller parts wear out too. Instant suggests a new sealing ring every 12 to 18 months ($9.99, Oct 2026) and notes that the silicone can absorb odors; Cuckoo suggests new rubber packing every couple of years ($14.99, out of stock in October 2026); Zojirushi sells inner lid sets and steam caps. The ARC-757SG’s glass lid ($8) was out of stock along with the pots.

A Saucepan May Be Enough

A stainless saucepan with a lid already cooks rice without a coating, a cord or counter space. Consumer NZ, New Zealand’s consumer group, timed and metered both: its rice cookers took 18 to 57 minutes to cook two cups of jasmine rice, most over 30, while ceramic cooktops took 20 to 25. Cooking rice three times a week for a year cost NZ$5.11 on the cooktops on average against NZ$7.35 in the rice cookers (August 2023).

Consumer NZ’s advice is to learn the appliances you have before buying another that may end up in landfill, and it expects a cooktop to outlast a benchtop appliance. A rice cooker earns its counter space when hands-off cooking, keep-warm or a large batch solves a problem you have most days. One limit: the pot from a rice cooker isn’t a saucepan, and Aroma’s manuals say not to put theirs on a stovetop or burner.

Energy: Cooking Versus Keeping Warm

Japan’s Agency for Natural Resources and Energy calls cutting keep-warm time the biggest single energy saving with a rice cooker. Its 2025 guide works from Energy Conservation Center Japan measurements and 2012 catalog averages for induction cookers that hold 5.5 to 8 rice cups: 158 Wh to cook a batch and 16.5 Wh for every hour on Warm. Ten hours on Warm uses more electricity than the cooking did, while three minutes of reheating in a microwave uses 35 Wh. The agency’s guidance is to keep rice warm for no more than about four hours, to cook twice rather than hold rice for seven or eight hours or more, and to unplug the cooker when it isn’t in use.

That matters most on a one-switch cooker. The Aroma Select Stainless drops to Warm by itself and stays there; its manual says to turn it off by unplugging it.

Living With a Stainless Pot

Expect some sticking and plan for it. Aroma’s manuals call for rinsing rice in a bowl of water rather than a strainer, filling to the line for the number of cups, and stirring in an extra half to one cup of water if the rice will sit on Warm for more than 20 minutes; they also say food shouldn’t stay on Warm for more than 12 hours. Rinsing won’t do much about arsenic: the FDA says it has a minimal effect on the arsenic in cooked rice and washes added nutrients off enriched white rice, while cooking rice in excess water and draining it cuts inorganic arsenic by 40 to 60 percent but strips those nutrients too.

To clean, let the pot cool, then soak it. Aroma allows hand washing or the top rack of a dishwasher, and Instant’s stainless pot is dishwasher-safe.

When It Wears Out

A rice cooker is an electrical appliance, and the EPA notes that electronics generally can’t go in a curbside recycling bin. Rice cookers are also on the not-accepted list of Best Buy’s in-store recycling program (Oct 2026), which leaves the decision to your city. In Fort Collins, Colorado, small kitchen appliances count as scrap metal: they go to drop-off sites rather than the curbside cart, and the city suggests donating working ones first.

If the base fails before the pot, a stainless pot can stay in the kitchen as a mixing bowl, or be recycled as scrap metal if your city accepts it.

Rice Cooker Questions

Is a stainless steel rice cooker non-toxic?

As far as the cooking surface goes, yes: an uncoated stainless pot takes the nonstick coating out of the question, provided the pot itself is uncoated and not just the body. It doesn’t make the cooker plastic-free, since the lid, steam vent and gasket sit in the steam and can be plastic or silicone, and stainless steel contains nickel, which matters if you have a nickel allergy.

Which rice cookers have a stainless steel inner pot?

Aroma’s Select Stainless ARC-753 and ARC-757SG, the Buffalo Classic and the Instant Pot Duo come with uncoated stainless pots. Elite Gourmet’s ERC2010B also has a stainless pot, but Elite doesn’t state the steel grade. Match the full model number, since the same brands sell coated models.

Which rice cookers have no Teflon or PFAS?

Any cooker whose pot is uncoated stainless steel or unglazed clay, including every model in the table above and VitaClay’s clay cookers. Among nonstick cookers, Zojirushi sells the NS-TPC10 as free of PFAS, including PTFE, and Our Place says its ceramic nonstick is made without PFAS and PTFE. A “PFOA-free” label alone doesn’t rule out PTFE.

Is the Zojirushi inner pot nonstick?

Yes. Zojirushi says its products use PTFE and that all of its rice cookers’ nonstick pans are PFOA-free. The NS-TPC10 is the exception: Zojirushi describes every surface that touches food on that model as free of PFAS, including PTFE, and of BPA. Replacement pans for both are in the keep-your-cooker table above.

Does Aroma make a stainless inner pot?

Yes, in its Select Stainless line: the ARC-753 and ARC-757SG cook in 304 stainless pots. Its digital Sensor Logic cookers, such as the ARC-914SBD, use ceramic-coated pots, and Aroma says most of its models sold with a nonstick pot can’t switch to a stainless one.

Is the Instant Pot a rice cooker?

It’s a pressure cooker with a rice program. The Duo 6QT cooks in an 18/8 stainless pot, so it makes rice without a coating; follow its manual’s grain chart and fill lines rather than a rice cooker’s cup markings. The six quarts describe the pot, not a rice capacity.

Is the Our Place rice cooker non-toxic?

It cooks in a ceramic nonstick pot that Our Place says is made without PFAS, PTFE, PFOA, lead or cadmium, under a stainless steel inner lid ($139 at Our Place, Oct 2026). That makes it a coated pot rather than an uncoated one: Our Place lists what the coating is made without, not what it is made of, and says to keep metal utensils, steel wool and abrasive cleaners off it.

Are aluminum rice cooker pots safe?

In the cookers covered here, aluminum sits under a coating or inside a layered pot rather than touching the rice: Instant’s spare ceramic pot is aluminum underneath, and Cuckoo’s stainless spare has an aluminum core between steel layers. Health Canada says the evidence linking aluminum to Alzheimer’s disease is conflicting and that acidic or salty food helps aluminum move from cookware into food. If the coating on an aluminum pot wears through to the metal, replace the pot. The aluminum cookware guide covers the metal itself.

Does rice stick in a stainless steel rice cooker?

Some, yes. Use the maker’s measuring cup and water lines, keep rice on Warm briefly or add water as Aroma’s manuals suggest, and soak the pot before washing it.
