A mini oven is an electric oven with a small cavity. It plugs into an ordinary socket, it heats a much smaller volume than a built-in oven, and because of that it draws less to do the same small job. This guide covers a test of 18 mini ovens, from tiny toaster ovens that weigh next to nothing to worktop machines with more capacity than some people's main oven.
What follows is recorded testing, translated. Nobody at Truthful Reviews has cooked in any of these.
What a mini oven actually is
The category is broader than the name suggests. The smallest models, the ones with a toasting slot, are also sold as toaster ovens; table ovens and bake-and-grill ovens are the same idea again. All of them run from a normal socket, all of them have a loading door and, depending on size, one to four shelf positions, and all of them have a limit on how long they can run in one go — the better the build, the longer that continuous run may be.
The heating elements sit exposed at the top and bottom of the cavity. Some models add a fan for a convection setting, which spreads the heated air evenly and reaches the same degree of cooking at a lower temperature, so it uses less. The case is metal, the front is glass, and the controls sit outside on a panel or on dials.
Two element materials turned up in this test: quartz and stainless steel. Quartz elements come up to heat very fast, which is why several of these ovens need no preheating phase at all. No oven in the field used infrared elements. Convection proper — where vents circulate the warm air without a separate fan — appeared on one model here, the Rommelsbacher BGS 1400. Low-temperature cooking, which needs precise and sustained control of the cavity temperature, appeared on exactly one oven in the field: the top pick.
Size is the decision
Capacity dictates what the oven is for, and the test is blunt about the gap between the marketing photographs and reality. Small ovens of 10 to 15 litres suit one or two people and small portions; a standard frozen pizza usually will not fit. From 20 litres upwards a normal 28-centimetre pizza generally goes in. Ovens of 25 to 40 litres have several shelf positions and can take a 29-centimetre cake tin, which puts them in the territory of a genuine second oven — still far smaller than the roughly 70 litres of a conventional built-in.
The rotisserie is the clearest example. Only one oven in the whole test, the Rommelsbacher BGE 1580/E, had a cavity big enough to actually turn a chicken on the spit. Every other oven with a rotating function was too small for it.
Power tracks size. The larger machines here run 1,200 to 2,000 watts; the smallest in the test managed 800 watts. Toppings, pizzas and rolls need less; baking bread and cakes, grilling a chicken or cooking raw meat wants 1,300 to 2,000 watts.
Insulation matters at least as much as wattage, because a poorly insulated cavity simply loses what it makes. On most of the ovens tested here the insulation was not good, and the outer surfaces ran hot in use. Double-glazed front glass and double-walled doors are the things to look for. A crumb tray, which sits on the floor of the cavity and catches what falls, was rated the single most useful accessory; not one oven in the field shipped with a pizza stone.

The picks
Top pick — Rommelsbacher BGE 1580/E
The clear winner, and it is not really mini. At 48 x 39 centimetres and 34 centimetres tall with a 30-litre cavity, this is a machine that should be given a permanent spot rather than carried about. It weighs 9.5 kg, which is still manageable, and it stands solidly on its feet — not a given in this field, where several ovens wobbled.
The body is galvanised, powder-coated stainless steel with a large glass door, and to the right of it sits a big touch-sensor panel with digital programme and time displays. In the box: a rack with a separate handle, a baking tray, a rotisserie set with its own handle, a crumb drawer and a genuinely good manual with starter recipes.
Four stainless-steel elements give 80 to 230 degrees. No preheating phase was needed in testing — the cavity reached 200 degrees in three minutes, which is where the difference from a built-in oven shows most plainly. Top and bottom heat are both available and convection can be switched in with either; there are also keep-warm and defrost programmes, and this was the only oven in the test with true low-temperature cooking. Temperature setting is the one irritation: the target has to be tapped up in single steps. The convection fan is rated at 50 dB and was found pleasantly quiet — around the level of a muted conversation or quiet radio.
In use it held up against a built-in oven. A 28-centimetre springform tin fitted, and a chocolate cake and a loaf of bread were both done in the same time as in a conventional oven. A pizza at the full 230 degrees browned its base as well as a good built-in would, and noticeably faster. The three shelf positions are genuinely usable. Interior lighting comes from a 25-watt lamp, which is not standard at this size. The rotisserie was tried with a small 1.2 kg chicken, which filled the cavity — anything bigger and the spit fouls the tray and stops turning — and took just under 2.5 hours to come out crisp.
Cleaning is where the build quality pays off. The cavity has a PTFE non-stick coating, the rack and rotisserie rod are chromed steel, the crumb tray galvanised steel and the baking tray enamelled and scratch-resistant. Even after the chicken, a short soak was enough. The double-glazed door comes apart easily for cleaning.
The case is insulated, but the top and side walls still run very hot in use; the double-glazed front stays merely warm and can be handled. It is the pricier oven of the three picks, and on the test's reading the versatility justifies it.

The portable one — Tefal Toast n' Grill TL6008
The pick for anyone who wants to take the oven with them — a caravan, a holiday let, a second kitchen. It measures 43 x 28 centimetres, stands only 22 centimetres tall and weighs 3.9 kg, which for the size reads heavy in a reassuring way: it sits still and does not rattle. The retro American styling is a surprise out of the box. In the box: a manual, a crumb tray, a grill rack and a small baking pan.
It is a 2-in-1. A slider opens a two-slice toasting slot on the top; close the slot and the cavity is sealed, worked through the front door. There are two shelf positions — on one the rack is anchored to the door and slides out as it opens, on the other it has to be pulled out by hand.
Four quartz elements and 1,300 watts gave good, quick baking results, and the small cavity works efficiently on small portions. A rotary control sets the browning level for toasting; a second sets 100 to 210 degrees for the oven. Six mini pizzas, two pretzels or rolls, or two toasted sandwiches, will fit. The 12-litre cavity, with a 24 x 16 centimetre pan, will not take a whole pizza — it is a very shallow oven.
The real omission is a timer: there is none, so on oven duty you watch it yourself. Build quality is high and the quartz technology grilled well. There are no other extras, which makes it an expensive machine for what it does.

The all-rounder — Ninja Combi 12-in-1
Part mini oven, part multicooker, part air fryer, and the reason it is here is that it does all three. Ninja lists twelve programmes: combi meals, combi crisp, combi bake, rice and pasta, sear and sauté, steam, slow cook, proving, bake, reheat, air fry and grill. A rocker switch picks between "Combi Cooker" and "Air Fryer", and fourteen further options sit beneath the two.
It is genuinely compact for what it holds, and heavy at 10.5 kg. Operation is broadly intuitive, but the sheer number of combinations will overwhelm anyone new to this kind of machine. A recipe book is included; it looks enormous but is mostly basics repeated across many languages.
The honest finding is that it needs recipes written for it. Without them there is no obvious way to know which programme, how long, at what temperature, or which of the two levels to use. Combi meals — a starch, a vegetable and a meat or fish cooked together as one dish — were the highlight, and they do save time and effort.
Not everything worked first time. Sweet potato chips did not crisp: done on top, not underneath, and a second run needed the food stirred through and the grill function added at the end. The tray has no handle for shaking, so that has to be solved another way. Cakes were not faster than in a conventional oven beyond skipping the preheat, but came out pleasantly moist. Simple things for children, such as oat traybakes, worked well. It runs fairly loudly on some programmes, and the light switches itself off shortly after being turned on, which is a small efficiency.
This is not a beginner's machine. For someone willing to spend time learning it, the range of options is the whole point.

Also tested
Rommelsbacher BGS 1400 — a smaller cavity than the winner and a mirrored glass front intended to improve efficiency; it sits close to the winner on capability, but the cavity was too short to run a chicken on the spit. It was the only oven in the test using convection vents rather than a fan. Search Amazon UK · Search Amazon US
Steinborg SB-3002 — 46 x 30 x 27 centimetres, stainless body, very large mirrored front, 20-litre cavity, four stainless elements and 1,600 watts, with crumb tray, rack and baking tray supplied. Baking was very good on that power, and the interior light is a plus, but at around 5 kg it is too light to sit steadily for its size, the outer surfaces ran extremely hot, and the badly translated manual explains none of the programmes.

Severin S72054 — one of the smallest, at 31 x 35 x 20 centimetres and 3 kg, with a 9-litre cavity that suits the smallest camper; sold in white or black. The rack is fixed and slides out with the door, there is a four-position on/off switch, top and bottom heat can be run separately or together, and the 60-minute timer with a chime is a plus. Toasted open sandwiches came out well but took markedly longer than the rest of the field, and it smoked heavily on its first burn-in. Little accessory kit and little comfort for what it is.

Steinborg 305 — very light and very compact, fine for rolls or mini pizzas, and its external heat stayed within bounds compared with others. The handle came off during unpacking — it had been glued, and caught on the packaging. Controls are top and bottom heat plus dials for temperature and timer, and the timer doubles as the on switch: it cannot be turned back, so an overshoot cannot be undone, and it carries on ticking loudly even unplugged. The mains lead is very short. Search Amazon UK · Search Amazon US
Steinborg SB-3001 — the slightly bigger sister at 20 litres, a little heavier and visibly more solid, with a longer lead. The same non-reversible ticking timer-as-on-switch problem applies. Baking results were entirely fine. The interesting extra is a removable grill plate on the top surface, which adds grilling space when the cavity is full; the top gets extremely hot as a result.

Stillstern MB45-LED 2G — nearly made the recommendations. A 45-litre cavity takes a 32-centimetre pizza, there are 13 programmes including braising, grilling and rotisserie chicken, heat-up is very quick, and pizza, cake and chips all came out as intended. Extras include a recipe book. It missed out on two counts: the display carries so much that several attempts were needed to set exactly what was wanted, and the glass door opens too easily and swings well past 90 degrees, so on a flat surface it has to rest on the worktop — and that door, and the rear, run enormously hot.

Woltu BF08 — did not convince. The red metal case looks better than the oven is: a very simple build, 2.6 kg of it, which shows in how steadily it stands. The stainless elements are exposed and the whole body including the single-glazed door runs extremely hot. Continuous running is capped at 30 minutes while the oven will reach 250 degrees. The test unit arrived with no manual at all, and the crumb drawer promised online is not supplied. Defrosting is about the extent of it. Search Amazon UK · Search Amazon US
Stillstern MB60-MX 2G — a maxi-mini: 60 litres, 14 kg, room for a 40-centimetre pizza and two trays stacked at once. Cleaning is its strength, with a smooth interior and a properly removable crumb tray that clips in and out. Accessories include an air-fryer basket, which will not replace a dedicated machine but produced respectable crisp chips. It browns faster than smaller rivals, so the temperature is worth dropping a little on the upper shelves. The elements sit relatively far apart, which did not show on the dishes tested but might leave the middle of a round cake behind. Dial control is clear, the 120-minute timer ticks quietly, and the door holds in stages and can be left ajar, though the split between "function" and "selection" dials is clumsy. It knocks and crackles in use, smells strongly on first heating, and gets very hot on every outer face. The lead is short for such a large machine. Search Amazon UK · Search Amazon US
OptimumX 20 L — a classic small oven at 33.5 x 45.8 x 28.9 centimetres and 6.5 kg, 1,380 watts, two elements top and bottom, with top/bottom heat, convection and fan heat combinable. Three dials control it; the timer only reaches 60 minutes and ticks loudly, the temperature dial is too loose to set precisely while the timer dial is stiff, and the otherwise sensible scale is hard to read. The door opens to 90 degrees but the empty oven tips forward under a firm push, and the tray and rack run stiffly in their runners. A standard loaf tin only just fits. Externally it gets clearly hot top, bottom, front and back and stays comparatively moderate at the sides. The baking let it down: cake was not fluffy and chips stayed slightly soggy.

Steinborg SB-500 — sold as the Ecosa Mini Backofen; small, light and deliberately basic, with one dial for temperature and one for the timer. The timer ticks conspicuously loudly and the lead is very short. On first heating it steams and smells strongly. The manual is brief, which matters little given how few functions there are. Opening the door draws the rack part-way out, though the cavity is so tight that getting hot food out stays fiddly. Bakes and gratins sit very close under the top elements, so the surface browned strongly while the inside still needed time — a lasagne came out appetisingly dark on top with the pasta not quite done. Lower and longer is the workaround. Outer surfaces run very hot all round. Search Amazon UK · Search Amazon US
Cecotec Bake & Toast 1090 — genuinely mini: 2.77 kg, easy to move and quick to stow, with two knobs for temperature and timer and nothing else. The elements and the small internal volume eat into usable space, so it is a snack oven rather than a gratin oven; the supplied handle for lifting the rack and tray is all the more useful in a cavity that tight. The manual is a strong point, with basics, cleaning and maintenance notes and sensible starting settings. The timer ticks very loudly. The runner logic is awkward: the tray fits only in the top or bottom position, never the middle, so it always sits close to a heat source and needs watching. First-heat smell was more moderate than most. Outside it gets very hot on the top and sides and stays more contained at the rear. Despite the name there is no toasting slot or toast function — toasting here means browning bread on the rack. Search Amazon UK · Search Amazon US
Rommelsbacher BG 1805/E — would have been a recommendation had its bigger sister not already won. 42 litres, 1,800 watts, top and bottom heat, convection, defrost and rotisserie, and four shelf levels, so there is a sensible height for anything. The supplied handles make lifting hot trays much easier and the double-glazed door holds heat well; the outer surfaces warm up but at an acceptable intensity for the class. The door opens and holds in stages, which helps when checking a cake. Against it: the door stages need a firm push, the empty oven can tip forward without the counterweight of food, and the 120-minute timer has no intermediate marks between the ten-minute steps. The tick is audible but acceptable. The manual is detailed enough to get started quickly. Search Amazon UK · Search Amazon US
How they were assessed
Baking and cooking performance came first, in a practical test with standard dishes — pizza, rolls, cake and gratin — watching how evenly each oven worked and then judging whether everything was cooked through and how it tasted.
Operation was judged on whether the manual was comprehensible, whether the oven could be driven intuitively, and whether routine handling such as swapping trays was straightforward. Capacity was recorded by checking how much could be cooked at once and which sizes of baking and gratin dish would fit.
Surface temperature was then measured across the case, door, handle and underside. Finally each oven was cleaned, with the ease of cleaning the cavity and the accessories assessed alongside build quality — material, fit and any other oddities noted along the way.
The short answers
Which is the best mini oven? The Rommelsbacher BGE 1580/E. It is well built, has plenty of power and extra functions, and can serve as the main oven in a small household.
What can you cook in one? Depending on cavity size, the same things as in a conventional oven. Pizzas, gratins, rolls, nuggets and fish fingers suit them particularly well.
What is a mini oven for? Cooking for which a full-size oven would be oversized.
What is a toaster oven? A mini oven that also has a toasting function alongside the baking function.
