The short answer
Buy the Zojirushi NS-TSC10 if you want the best rice of any cooker that ships a basket. Zojirushi lists a steaming basketin the box alongside the measuring cup, spatula and spatula holder, the cooker has a Steam setting on the panel, and it is a Micom fuzzy-logic machine at 610 W — so the rice is not a compromise you accepted to get the tray. Buy the Tiger JAX-T10U if the point is to cook dinner and the rice in one appliance at the same time: its tacookplate is the only tray here that was designed for synchronous cooking rather than retrofitted onto a rice cooker, and it is made in Japan at 641 W. Buy the Aroma ARC-994SGif you want the steam function that is actually documented — Aroma is the only maker of the four that prints a step-by-step “Steam & Cook” procedure in its own manual, and the only one honest enough to publish the limit that comes with it. It is also the cheapest machine here by a wide margin. Buy the Instant Pot Duo if you would rather have a stainless steamer rack in a pressure cooker that also makes rice, and you are willing to give up fuzzy-logic rice to get seven other functions.
Why “has a steam function” is the wrong thing to shop on
Nearly every rice cooker sold today has the word Steam somewhere on the panel or the box, and the word on its own tells you almost nothing. A rice cooker is a steam appliance: it boils water in a sealed pot. Pressing Steam usually just runs the element for a time you set instead of stopping when the water is gone. So the question that decides a purchase is not whether the machine can steam. It is whether the manufacturer gives you the three things that make steaming useful.
- Is the tray actually in the box?This is the one buyers get caught by, because listings describe the function and photograph the accessory without ever saying it is included. All four cookers here ship a tray or rack — that is the entry requirement for this page, and it is why the field is four machines rather than fourteen.
- Can it steam and cook rice at the same time? This is the feature worth paying for and the one least often documented. Steaming broccoli in a rice cooker instead of a saucepan saves you a pan. Steaming chicken and broccoli above rice that is cooking underneath itsaves you a pan, a burner and a timing problem — it is a whole weeknight dinner from one appliance. Two of the four cookers here document that procedure. The other two document the tray and leave you to work it out.
- How much does the tray actually hold, and what is it made of? Here the documentation runs out across the board. Not one of these four manufacturers publishes a tray volume or a tray material on its product page, so this page does not print one either. That gap is the finding, and a page that filled it with estimates would be making up the single number you most wanted.
How we ranked them
Entry requirement: the manufacturer states that a tray, basket or rack comes with the cooker. Then, in order: whether the maker documents steaming and cooking simultaneously, then how good the rice is underneath it (because a steamer tray does not change the fact that you bought a rice cooker), then what the published documentation supports, then price. As everywhere on this site, we have cooked in none of these machines— every figure comes from the manufacturer's own product page or manual, cited on each card, and every pick carries a real disqualifying con. The full rubric is in our methodology. Prices move, so we do not print them in prose; the live price sits on each card.

1. Zojirushi NS-TSC10 — the best rice that comes with a basket
The Zojirushi NS-TSC10wins because it is the only cooker here where the tray is an addition to a genuinely excellent rice cooker rather than the reason you tolerated a mediocre one. Zojirushi's own product page lists the accessories as a steaming basket, a rice measuring cup, a nonstick rice spatula and a spatula holder, and the panel carries Steam and cake settings that the otherwise-superior NS-ZCC10 Neuro Fuzzy does not have. Underneath that it is a Micom fuzzy-logic machine: the microcomputer adjusts heat through the cook instead of running a fixed timer, which is the whole reason a $200 rice cooker beats a $30 one. It draws 610 W, the lowest of any Zojirushi we cover, and holds 5.5 cups uncooked.
Two honest limits. First, Zojirushi does not publish a numbered procedure for steaming a dish while rice cooks beneath it — the basket and the Steam setting are both documented, the combination is not, so treat simultaneous cooking here as something you will work out rather than something the manual walks you through. Second, this is the made-in-China Zojirushi, not the made-in-Japan one: if Japanese manufacturing is specifically why you are buying the brand, the NS-ZCC10 is the model that has it and it does not come with a basket. That is the trade this page exists to surface. The interior pot is nonstick and will wear before a stainless multicooker pot does.
2. Tiger JAX-T10U — the only tray built for the job
Every other tray on this page is a steamer that happens to sit in a rice cooker. Tiger's tacook plate is the opposite: the JAX-T10Uwas designed around synchronous cooking, where a dish steams on the plate while rice cooks in the pot below from the same 641 W element. Tiger publishes the wattage, the 1.0 L / 5.5-cup capacity, ten named auto-cook settings and that the cooker is made in Japan. If the reason you searched for a rice cooker with a steamer basket is “I want one appliance to make dinner,” this is the machine that was actually engineered for that sentence, and it is the one we would pick for it.
The limit is capacity, and it is a real one. The tacook plate steams a portion of protein or vegetables, not a second course— think two chicken thighs or a bowl of broccoli, not dinner for four. Tiger's US documentation is also thinner than Zojirushi's: the inner pot material is not clearly published, which on a machine at this price is a fair thing to want. And it is Micom rather than induction, so the rice is very good without being the best on this site — induction against fuzzy logic is where that difference gets argued properly.
3. Aroma ARC-994SG — the documented one, and the cheap one
The Aroma ARC-994SG is third on rice quality and first on honesty, and if your budget is tight it is the pick. Aroma lists a Steam Trayin the manual's parts identification, describes the Steam program as steaming “healthy sides and main courses using the included steam tray,” and then does the thing none of the others do: it prints a numbered Steam & Cookprocedure — measure and rinse the rice, add it to the inner pot, load the tray, lower it in, close the lid, select White Rice, Brown Rice or Steam — and attaches a published caution to it:
“Do not attempt to cook more than 2 cups of uncooked rice when steaming and cooking simultaneously.”
That single sentence is worth more than any marketing claim on this page. It tells you the feature is real, it tells you the machine was tested doing it, and it tells you the constraint — on a 4-cup cooker, simultaneous steaming costs you half your rice capacity. Nobody else publishes a number like that, which is why the cheapest machine here ranks third rather than fourth. It also adds Slow Cook (2 to 10 hours), Sauté-then-Simmer, Oatmeal and a 15-hour delay timer, on a ceramic-coated nonstick pot, at 450 W — the lowest draw of anything on this page.
The cons are the ones you would expect at the price. It is sensor logic rather than true fuzzy logic, so the rice is good rather than excellent; the pot is coated and will eventually wear; and 4 cups uncooked (8 cooked) is the smallest capacity here before you even apply the 2-cup simultaneous-cooking limit. If you cook for more than two people and want to steam at the same time, this is the wrong machine and the Tiger or the Zojirushi is the right one.
4. Instant Pot Duo — the stainless rack, and the other seven functions
The Instant Pot Duo earns a place here on a technicality that turns out to matter: Instant Brands states that it “includes a stainless steel steamer rack,” and it is the only stainlesssteaming accessory on this page — nothing to scratch, nothing to flake, dishwasher-safe like the 18/8 tri-ply pot it sits in. Steam is one of the seven named functions, and the Duo also publishes the figures almost nobody else does: 1,000 W, 6 qt / 5.7 L, and a 10.2–11.6 psi high working pressure on the manual. If what you want is one machine that steams, pressure-cooks, slow-cooks, sautés and makes rice, this is the cheapest well-documented way to get it.
It is fourth because of the rice, not the rack. A multicooker makes good rice; a fuzzy-logic cooker makes better rice, and that gap is the honest center of rice cooker versus Instant Pot. A rack is also not a basket: it is a trivet designed to lift a dish or a bowl out of the water, so loose vegetables need a heatproof dish or a bowl on top of it rather than going straight on. And at 1,000 W it draws more than twice the Aroma, which only matters if you steam most days — what a rice cooker actually costs to run does that arithmetic.
Steaming above cooking rice: what actually happens in the pot
Worth understanding before you buy, because it explains both why the feature works and why the makers attach limits to it. A rice cooker holds its pot at boiling until the free water is gone. The steam that would otherwise condense on the lid and drip back is, when you put a tray in the path, condensing on your food instead — which is why steaming above rice costs you no extra energy and barely any extra time. The two constraints follow directly from that.
First, the drip goes down. Whatever you steam above rice will drip onto it: chicken juices, fish, anything marinated. Sometimes that is the point and sometimes it ruins a pot of plain rice, so the rule of thumb is to steam things you would happily have flavored the rice with, and to steam the rest in a separate run. Second, the tray steals headroom. Rice expands to roughly double its dry volume and needs space above it to boil without the lid; a tray sitting in that space is why Aroma caps simultaneous cooking at 2 cups of uncooked rice in a 4-cup machine. Expect roughly half the rated rice capacity when the tray is in, on any cooker, whether or not the maker prints the number.
Third, and this one is not in any manual: steamed food is done when it is done, and rice is done when the cooker says so. They are rarely the same moment. Vegetables want five to ten minutes and a white-rice cycle wants thirty-something, so the practical technique is to start the rice, let it run, and add the tray partway through — which is exactly the sequencing how to steam vegetables in a rice cooker works through step by step for a cooker you already own.
Who should skip this category entirely
If steaming is the main event rather than a bonus, a rice cooker is the wrong appliance and we would rather say so than sell you one. A dedicated stacking steamer gives you two or three tiers and far more volume than any tray on this page, and a pressure cooker steams faster and holds more. Steaming vegetables in an Instant Pot covers that route, and which kitchen appliance you need is the honest starting point if you have not settled on a category. If what you would put on the rack is meat rather than vegetables, the best pressure cookers for meat is the page to read instead — pressure, not steam, is what makes a cheap cut tender.
If what you actually want is the best rice and you will never use a tray, buy the outright best rice cookerand ignore this page — the top of that list does not include a basket and does not need to. And if you are cooking for one or two in a small kitchen, the best small rice cookers ranks the same field on footprint, where the Aroma also does well.
What we would buy
Best rice, basket included: the Zojirushi NS-TSC10. One-appliance weeknight dinners: the Tiger JAX-T10U, for the tacook plate and the documentation behind it. Tight budget, or you want the procedure in writing: the Aroma ARC-994SG, remembering the published 2-cup ceiling when the tray is in. You would rather have a pressure cooker: the Instant Pot Duo, with a stainless rack and seven functions, accepting that the rice is a step down.
