Non-Toxic Rice Cookers: Which Pots Are Uncoated?

A stainless-steel rice cooker can still have a nonstick-coated pot. If you want the rice to touch uncoated steel, start with Aroma’s Select Stainless models, the Tatung TAC-11KN, or the Instant Pot Duo 6QT you may already own. Choose by the amount of rice you normally cook, then check whether a replacement pot is available. A working appliance does not need replacing just because another one has a different cooking surface.

• Usually cooking a small batch? The Aroma ARC-753SG takes 1–3 dry rice-measuring cups of white rice. It has a 304 stainless pot and one cook switch.
• Need more than three dry measures? The larger Aroma ARC-757SG takes 2–7 rice-measuring cups of white rice, with the same simple controls. Its two-measure minimum matters if you also make smaller batches.
• Need larger batches and a steamer? The silver US Tatung TAC-11KN(UL) holds up to 11 dry rice-measuring cups and heats through a separate outer water pot. It needs a different measuring routine from an ordinary one-pot cooker.
• Already have a Duo 6QT or a suitable lidded saucepan? Try its rice instructions first. You may not need another appliance.

The main trade-off is cleanup: uncoated steel can hold onto a layer of rice. It also has no nonstick layer to wear away. Neither feature proves that the whole cooker will last longer, so the pot, replacement parts and your cooking habits all belong in the decision.

Which cooker fits the rice you make?

“Six cups” can mean six cups of cooked rice or six measures of dry rice. Those are very different machines. Aroma’s supplied measure is three-quarters of a standard US cup; use that measure with its fill lines. The white-rice ranges below come from its manuals, not a conversion from the appliance’s quart capacity.

Model	Rice capacity	What changes the choice
Aroma ARC-753SG / SGB	1–3 dry white-rice measures; up to 6 cooked cups	Smaller batches; Cook/Warm switch
Aroma ARC-757SG	2–7 dry white-rice measures; up to 14 cooked cups	More room, but a two-measure minimum
Tatung TAC-11KN	Up to 11 dry rice measures / 22 cooked cups	Water goes in both the rice pot and the outer heating pot
Instant Pot Duo 6QT	Six-quart vessel, not six dry cups of rice	Pressure-cooking fill limits and rice-specific instructions apply
Cuckoo CRP-LHTAR0609F	Up to 6 dry rice measures / 12 cooked cups	Induction and pressure functions; verify the complete model number

Brown rice needs its own water and capacity guidance. Do not carry a white-rice maximum into a brown-rice recipe or equate the table’s capacities with servings. If brown rice is your everyday staple, check the manual’s instructions and the controls you want before choosing on pot material alone.

Aroma Select Stainless: pick the size before the color

The ARC-753SG and black ARC-753SGB share a small-capacity stainless-pot design; the ARC-757SG is the larger option. Both sizes use a 304 stainless cooking pot, a glass lid and a Cook/Warm switch rather than separate white- and brown-rice buttons. Choose the small one if one dry measure is your normal batch. Buying the larger cooker for occasional guests means accepting its larger minimum the rest of the time.

Aroma catalogs replacement pots for both sizes, but both were out of stock when checked on September 9, 2026. That makes them replaceable in principle, not a guaranteed quick repair. Check the 753 spare pot or 757 spare pot before relying on parts availability. The stainless inner pot is not intended for use on a stovetop.

Tatung TAC-11KN: larger batches with indirect heating

Tatung specifies SUS304 stainless for the inner pot, its lid, the steamer rack and the outer heating pot. Water in that outer pot supplies the indirect heat; water mixed with rice in the inner pot serves a separate purpose. Follow both measurements in the instructions. The included steaming rack is useful if the cooker will handle more than rice.

For a US kitchen, check that the listing is the 120-volt TAC-11KN(UL), not an imported version. Tatung’s US support says it does not service Taiwan-spec imports. Ask support to confirm the current spare-pot part and capacity before ordering a replacement. A cataloged ten-cup replacement does not preserve an eleven-cup capacity.

Instant Pot Duo 6QT: use the rice function you already have

The Duo 6QT has an 18/8 stainless inner pot with a tri-ply base and a rice program. It is a pressure multicooker, not a direct substitute for every dedicated rice cooker’s settings. Check your manual for the rice type, minimum liquid, expanding-food fill limit and pressure release. Time under pressure is not the total time from adding ingredients to opening the lid.

If you already have one, start there. If its pot needs replacing, the six-quart Instant Pot stainless inner pot on Amazon is a separate purchase from a new cooker. Check its compatibility list against your full model number; it does not fit Duo Evo Plus. Six-quart pots are not universally interchangeable.

Cuckoo: one letter changes the inner pot

The CRP-LHTAR0609F combines induction and twin-pressure cooking with an included three-ply uncoated stainless pot. The similar CRP-LHTR0609F, without the A, comes with an Xwall-coated pot. The names are close enough that checking the photo or “stainless” in a retailer’s title is not sufficient.

Cuckoo also sells a CRI-HAC0610N stainless replacement pot for specified models, including LHTAR. Its listing showed stock on September 9. It is not compatible with LHTR. This is an option for someone who wants those cooking functions, not a reason to replace a simpler cooker that already meets their needs.

Other stainless and clay options

Buffalo Classic KWBSC10-II: Buffalo specifies an uncoated clad-stainless pot and white-rice, brown-rice, porridge and soup programs. Its “five-cup” product label does not clearly identify the dry/cooked basis on the page checked, so confirm the manual before comparing it with Aroma’s capacities. See the Buffalo Classic five-cup model on Amazon.

Elite Gourmet ERC2010B: the manufacturer describes a food-grade stainless pot and five dry cups / ten cooked cups. It does not state the steel grade. Confirm availability and a compatible spare before treating it as an alternative to the leading picks.

Tayama TRSC-10R: retailer specifications describe a removable stainless pot and steaming function. A current manufacturer manual and replacement-pot route were not available in the sources checked. That is a reason to ask the seller for those details, not evidence that the cooker is unsafe.

VitaClay VF7700-6: the maker specifies an unglazed Zisha clay pot. Unglazed clay is different from ceramic nonstick coating, but its material name alone does not establish food-contact safety. Its model manual says to keep liquid in the pot, let it cool before washing and hand-wash rather than use a dishwasher. Choose it only if that gentler handling fits your kitchen.

What the coated models disclose

The other models weighed for this page cook on a coating. Zojirushi’s NS-ZCC10 and NS-TPC10, Cuckoo’s CR-0675F and Aroma’s ARC-914SBD pair a nonstick or ceramic surface with an undisclosed pot base. Cuckoo’s CRP-DHSR0609FD uses an X-Wall Diamond coating; Tiger’s JAX-T18U, PFAS nonstick over aluminum; Panasonic’s SR-HZ106, a fluorine and diamond hard-coating; Dash’s DRCM200, a nonstick containing PTFE. Hamilton Beach’s 37548MN and GreenPan’s Bistro 8-Cup are ceramic nonstick over a base neither maker states. Caraway’s Petite Cooker is a coated stovetop pot rather than a rice cooker. A coating is a preference, not a defect; the shortlist above is limited to bare pots.

Uncoated, ceramic and PFAS-free mean different things

The surface inside the pot matters more than the finish on the appliance. A stainless outer shell, inner lid or pot exterior can sit alongside a coated rice-contact surface. Check each named component. An uncoated pot also does not mean that the lid, steam path, seals and utensils are plastic-free.

• Uncoated stainless: rice touches steel, with no nonstick layer over it. Expect a different cleaning routine.
• Ceramic nonstick: a coating, not a solid ceramic or clay vessel. Our Place’s rice cooker, for example, uses a ceramic nonstick inner pot and a stainless inner lid. The maker describes its cooking surfaces as made without PFAS, PTFE and PFOA; it is still a coated choice.
• PFOA-free: this does not by itself mean PTFE-free, PFAS-free or uncoated. Those claims are not interchangeable.
• PFAS-free: check the exact claim and the parts it covers. Zojirushi’s NS-TPC10 is described as PFAS-free on food-contact surfaces but still has a nonstick cooking pan.

If you prefer nonstick cleanup, a disclosed ceramic-coated model may fit that preference. It should not be presented as bare steel, and the coating still needs care. Our Place and GreenPan both sell ceramic-coated rice cookers; neither brand’s use of “non-toxic” establishes a longer appliance life. Look for a model-specific spare pan before buying.

Does a coating mean you need a new cooker?

No. The FDA describes negligible PFAS migration from authorized polymerized nonstick cookware coatings. That is not a certification of any particular appliance, but it does not support treating every coated rice cooker as dangerous. Follow your manufacturer’s care guidance, check any applicable recall, and ask about a damaged pot before deciding to replace the machine.

Stainless steel is not universally suitable, either. It commonly contains nickel; Health Canada advises people with a nickel allergy not to use nickel-containing cookware. The 18/8 and 18/10 guide explains the grade labels. Neither label means nickel-free.

Changing the pot material is also not an arsenic-removal method. The FDA’s rice guidance concerns the rice and cooking method: excess-water cooking followed by draining can reduce inorganic arsenic, but also removes nutrients from enriched rice. Rinsing alone has little effect on arsenic. A new cooker should not be sold as a solution to a different problem.

Check parts before replacing the whole cooker

A usable base with a damaged removable pot may need a part, not a replacement appliance. Match the complete model number and get the manufacturer’s compatibility confirmation. Diameter and quart capacity alone are not enough. Aroma specifically warns that its stainless pots are generally not a conversion for cookers supplied with nonstick pots.

Check the lid and other routinely replaced parts at the same time. Aroma’s pot listings show why “replacement available” needs a stock check; Tatung’s import restrictions show why buying the right regional model matters. A warranty is useful backup, but its length is not a prediction of how long a cooker will last.

When repair is no longer practical, ask your local waste provider about the electrical base, separate metal pot and packaging individually. Accepted recycling materials vary by local program. Do not put an appliance in the curbside bin because part of it is steel.

A saucepan may be enough

A suitable pot with a close-fitting lid can cook rice without adding another electrical appliance. Use the instructions for your rice variety and cooking method rather than one universal rice-to-water ratio. If stovetop rice already works for you, keep that routine. A dedicated machine earns its counter space when its capacity and hands-off cooking solve an everyday problem.

Living with a stainless pot

Start with the supplied measuring cup and the manual’s chart for your grain. Rinsing, soaking and water ratios vary; more water is not a universal fix for sticking. Aroma’s manuals warn that extended warming can dry rice and increase sticking. A Cook/Warm switch does not mean the cooker shuts off after dinner.

Let the pot cool, soak stuck rice and clean it as the manufacturer directs. Do not immerse the electrical base. Aroma permits its removable pot in the dishwasher’s top rack or hand washing; that does not establish dishwasher compatibility for a different cooker. Pressure models also need their seals and valves maintained according to the manual.

Before ordering, check the appliance’s footprint and clearance for opening the lid, not just its rice capacity. If a listing is unclear about the cooking surface or a replacement part, ask the maker. Missing information is a reason to pause, not proof that the pot has a coating.

Buy for your usual batch

For one to three dry measures of white rice, start with the small Aroma. If you regularly need four to seven, compare the ARC-757SG with Tatung’s larger capacity and different steaming setup. Keep a suitable Duo or saucepan in service if it already does the job. A correctly sized cooker with an obtainable spare pot is a more useful goal than the strongest claim on the box.

The same use-first approach applies to the plastic-free electric kettle and slow cooker decisions: check the food-contact parts, then whether the appliance is needed. For changes beyond the countertop, start with the zero-waste kitchen guide.

Rice cooker questions

Is a stainless steel rice cooker non-toxic?

An uncoated stainless inner pot avoids a nonstick cooking layer. That does not establish the safety of the whole appliance or make it nickel-free. Check the pot, lid and other food-contact parts, and follow the maker’s care instructions. A stainless exterior alone tells you little about the surface touching the rice.

Which rice cookers have a stainless steel inner pot?

Aroma Select Stainless ARC-753SG/SGB and ARC-757SG, Tatung TAC-11KN, Instant Pot Duo 6QT, and Cuckoo CRP-LHTAR0609F have stainless cooking pots. Check the full model number and included pot. A different cooker from the same brand may have a coated surface.

Is the Zojirushi inner pot nonstick?

The NS-ZCC10 and NS-TPC10 both have nonstick cooking pans. Zojirushi describes the NS-TPC10’s food-contact surfaces as PFAS-free, including PTFE and PFOA. It is still a coated pan, not a bare stainless alternative. Do not use a PFOA-free claim on another model as a substitute for that model’s full coating disclosure.

Does Aroma make a stainless inner pot?

Yes. Select Stainless ARC-753SG/SGB and ARC-757SG use 304 stainless cooking pots. The ARC-914SBD is different: Aroma describes its pot as ceramic-coated. Aroma sells model-specific spare pots, but they are not a general stainless upgrade for its coated cookers. Check compatibility and stock before ordering.

Are aluminum rice cooker pots safe?

The answer depends on the pot’s construction, cooking surface and condition, not the word aluminum alone. Aluminum may sit beneath a coating or within a layered pot rather than touching the rice. Follow the exact model’s instructions for care and damaged surfaces. The aluminum cookware guide explains the material separately.

Does Cuckoo make a stainless steel rice cooker?

Yes. CRP-LHTAR0609F includes an uncoated three-ply stainless pot. CRP-LHTR0609F, without the A, has an Xwall-coated pot and cannot take the CRI-HAC0610N stainless replacement. Cuckoo lists other compatible models for that separate pot; check the included configuration rather than assuming every Cuckoo cooks on the same surface.

Is the Instant Pot a rice cooker?

The Duo 6QT is a pressure multicooker with a rice program and an 18/8 stainless inner pot. If you own one, follow its rice instructions before buying a dedicated machine. Check your model’s grain, liquid, fill-limit and pressure-release guidance. Its six-quart volume is not a six-cup dry-rice capacity.

Does rice stick in a stainless steel rice cooker?

It can. Use the model’s measuring cup and grain-specific water instructions, avoid leaving rice warming longer than needed, and soak stuck rice before cleaning. Expect more cleanup than with a nonstick surface.
