Best Mini Oven 2026: 10 Countertop Ovens Ranked by Litres

Forty-five litres is the sweet spot on this page. It is enough for a small roasting tin or a full tray of chips, and it stops well short of the 60-litre machines that take over a worktop run. Behind that cavity sits 2000W and a ceiling of 230C, which works out at roughly 44 watts for every litre of oven. By contrast the NETTA 45L further down has the same capacity with about 1,450W once its hotplates are accounted for.

Crucially, this is one of only two listings here that publish a convection function, and the only one that pairs the fan with a rotisserie. A fan matters more than the spinning spit does: it circulates air so a tray browns evenly instead of needing a turn halfway. The housing is stainless steel with double glazing and protective grounding, and a baking tray comes in the box.

Its 4.4 stars rest on 3,232 ratings, and that is the point. It is the one large review pool on this page that is not shared with sibling models, which makes it the most tested machine here by a wide margin. Two honest caveats. At GBP 149.95 it is almost forty pounds dearer than anything else on the list. And the spec table reads 56D x 40.5W x 35H, making it the only oven here published as deeper than it is wide, so measure for roughly 56cm across the front before you commit.

Sixty litres for GBP 109.99 works out at about GBP 1.83 a litre, and the comparison that makes the point is on this very list. The Cooks Professional at number nine costs exactly the same GBP 109.99 and gives you twenty-eight litres. Same money, thirty-two litres more cavity, which is the difference between a big toaster oven and a genuine second oven for a bird or a full tray in December.

Meanwhile it publishes what most rivals here leave blank: 2500W, a range of 100C to 230C, a 60-minute timer, an oven light and double insulation. It even labels its dimensions axis by axis, H 39.7cm x W 64.5cm x D 47cm, which no other listing on the page bothers to do. It is also one of only two here to claim convection, although its own bullet says that is unlike other mini ovens, and the TZS at number one sits on the same results page publishing a fan of its own.

The cost is counter space, and it is not small. At 64.5cm wide and 47cm deep it claims about 0.30 square metres of worktop, and the external box works out at roughly 120 litres for a 60-litre cavity, so half of what you make room for is casing rather than oven. Its 4.2 over 623 ratings is a step below the TZS in both score and sample.

If the room has no hob in it at all, this changes the shopping list. A bedsit, a caravan, an annexe or a holiday let needs one appliance that boils a pan and roasts a tray, and this is the largest oven among the hotplate models here: 45 litres underneath, an electric grill, and two integrated burners on the lid. The 120-minute timer is twice what most rivals on this page offer, which matters on a slow roast where a 60-minute timer means getting up to reset it.

However, the arithmetic on this listing is worth reading before you buy. Bullet three advertises a high-power 2850W total output. Bullet two, one line above it, gives the split: an 800W burner and a 600W burner. Take those away and roughly 1,450W is left for the oven and the grill, which is fifty watts less than the 1,500W NETTA quotes for its own 30-litre oven with no hotplates at all. Per litre of cavity that is about 32 watts against 50, so it heats a bigger space with less to do it. It is a cooking station first and an oven second.

Two more things to weigh. At 58.1cm wide and 41cm tall it is the tallest machine on this page, taller even than the 60-litre pair, and the burners sit on the lid, so anything in the cupboard above has to clear a pan as well as the case. And its 4.2 from 1,230 ratings is the identical figure shown on NETTA's 35-litre and 30-litre models, three different sizes with one shared pool rather than a verdict on this one.

For a student room or a single household, this is the practical size. Thirty litres handles toast, jacket potatoes, a tray of chips and reheating, and at 51cm wide by 38.6cm deep the table top mini oven sits on a normal worktop without a rethink of where the kettle goes. Behind it is 1500W, which comes to 50 watts a litre, the joint-highest heat-to-capacity ratio on this page and a good deal more than the 32 you get from the NETTA 45L above.

Meanwhile it does something several rivals here do not: it publishes both ends of its temperature range, 100C to 230C. That 230C ceiling is the same figure given by every listing on this page that publishes one at all, so the useful information is the floor. Its spec table also lists it as insulated, although no bullet on the listing explains what that means in practice.

Two reasons it is fourth rather than higher. There is no fan claim anywhere on the listing, so trays want turning halfway, and no timer duration is published at all, which on a small oven is a real omission. Its 4.4 over 505 ratings also happens to be the identical figure shown on the 60-litre Prodex at number six, so treat it as one shared pool rather than 505 verdicts on this oven.

At GBP 57.99 this is the cheapest oven on the page, some GBP 91.96 below the dearest, and it still gives you thirty litres. It is also physically modest with it: 48.6cm wide, 37cm deep and just 32cm tall, which makes it the shortest machine here and one of the easiest to slide under a wall cupboard.

The genuinely interesting number is the temperature floor. HOMCOM publishes 60C to 230C, and nothing else on this page goes anywhere near that bottom end. The Cooks Professional stops at 90C, while the Prodex 30L and the Igenix both floor out at 100C, a full forty degrees higher. For holding a plate warm or proving dough, that is the one axis where the cheapest small oven on the list leads outright. The door is double-layer glass and the wire rack, baking pan and tray handle are dishwasher safe.

By contrast, the listing never publishes a wattage anywhere, in the title, the bullets or the spec table, so heat-up time is a guess. Its Special feature field is catalogue filler that simply restates the title and the capacity. And 90 ratings at 4.2 stars is an early sample rather than a settled verdict. The one line about what fits inside, up to 8 slices of bread or 12 chicken wings, is HOMCOM's own measure of one rack, not a standard anyone else reports.

This is the most cavity per pound on the page: GBP 99.99 for sixty litres, about GBP 1.67 a litre, ten pounds under the Igenix at number two. And on the published data the two are the same box. Both list 47D x 64.5W x 39.7H centimetres, to the millimetre, and both list sixty litres. Both model numbers even carry the same four digits, IG-7161 and PX-7161-B, while Prodex's own thirty-litre is a PX7030B, a number that encodes its capacity. There is nothing in 7161 that says sixty.

However, the ten pounds buys information. The Igenix listing publishes 2500W, a range of 100C to 230C, a 60-minute timer, an oven light and double insulation. This one publishes sixty litres, an aluminium baking tray, and the words all-in-one, versatile functionality and sleek black finish. No wattage, no temperature range, no timer duration, although the spec table does list Timer as a special feature with nothing anywhere to say how long it runs.

In practice that means the fan, the light and the 2500W you are picturing come from the other listing, not this one. If it is the same machine you save a tenner; if it is not, you have bought a 60-litre oven with no published power figure. Its 4.4 from 505 ratings is also the identical count shown on the 30-litre Prodex, so that is a shared pool too.

This is the narrower version of the machine at number three, and the reason to choose it is width rather than price. At 53.1cm across and 37.5cm deep it asks for five centimetres less worktop than the 45-litre model, which in a small kitchen can be the whole argument. You still get a 35-litre oven, an electric grill, two integrated hotplates and the same 120-minute timer, and NETTA publishes a weight of 10.8kg, one of only two ovens on this page that publish one at all.

However, ten pounds more buys the 45-litre version with ten more litres inside, so whenever the space allows, that is the better buy. Per litre this works out at about GBP 2.57 against GBP 2.22 for its bigger brother, and oven-only rivals at this money give you far more cavity again.

The power figure needs care here. The listing quotes 2850W as a combined output and, unlike the 45-litre model, never breaks out what the two hotplates take, so what the oven itself draws is simply not published. No temperature range is given either. And the 1,230 ratings at 4.2 are the same pool shown on the other two NETTA ovens on this page, which makes the score a family average rather than a report on this size.

This is the compact oven for people who will move it. At 49.8cm wide and 32.8cm deep it takes the least worktop of anything here, and at 7.2kg it is the lightest weight published on the page, which makes it the realistic choice for a campervan or for going back in a cupboard between uses. Two more litres than the 28-litre Cooks at number nine, in noticeably less space.

Its 1500W is also the number that exposes the headline finding. Thirty litres on 1500W is 50 watts a litre, and this oven has no hotplates sharing that supply. NETTA's own 45-litre station, once its 800W and 600W burners are subtracted from the advertised 2850W, is left with about 1,450W. In other words the small, cheap oven is the more powerful one.

It sits eighth on value rather than on merit. GBP 69.99 is five pounds more than the Prodex at number four for the same thirty litres and the same 1500W, with a lower 4.2 score and only a 60-minute timer. NETTA publishes adjustable heat from 100C but never says where it stops, so the ceiling is unknown. And the 1,230 ratings are the family pool again, shared with the 35-litre and 45-litre models.

There are two good reasons this one is here. It fits an oven, a large hob and a small hob into 49cm of width, the least frontage any cooker replacement on this list asks for, and it publishes a 90C floor, the second lowest here, which is useful for holding food warm. Its 4.5 stars are the joint-highest score on the page.

By contrast the value is the weakest on the list. GBP 109.99 for twenty-eight litres works out at about GBP 3.93 a litre, the dearest capacity here by some way, and the same GBP 109.99 buys the Igenix with sixty litres, while GBP 99.99 buys the NETTA with forty-five litres and two hotplates. The footprint is not as thrifty as the width suggests either: 49cm by 39cm is more worktop than the HOMCOM and NETTA 30-litre ovens on this page, both of which hold more food.

The listing is also quieter than the price implies. No wattage is published at all, and although the spec table lists a timer and a bullet mentions precision timing, no duration appears anywhere. The line about a smaller footprint helping to save on electricity compared with a full oven is the maker's claim with no figure attached to it. The 4.5 rests on 101 ratings, the third thinnest sample on the page. The title reads Mini Portable Oven, yet no weight is published to tell you how portable that is.
