A mini oven is one of the most useful appliances you can put on a worktop, but it is also one of the easiest to get wrong. Buy one that is too small and you cannot fit a pizza in it; buy one that is too big and it swallows half your counter. The choice has also got more complicated, because the line between a mini oven and an air fryer has blurred, and many of today’s best-selling models do both.

Is a mini oven worth it?
For most households, a mini oven earns its place if it gets used several times a week. A typical built-in single oven draws 2 to 3kW and has to heat a cavity of 60 to 70 litres. A 1,500W mini oven with a 20-litre cavity heats far faster and has much less air to keep hot, so for small jobs such as a couple of chicken breasts, a tray of oven chips or a frozen pizza it will usually use a fraction of the electricity.
What to look for in a mini oven
Capacity
Around 9 to 12 litres is enough for toast, a jacket potato or a small ready meal for one. From about 20 litres you can fit a whole chicken or a 12-inch pizza, which is where most people should be looking. Ovens of 26 litres or more suit couples and families but take up considerably more worktop space.
Convection fan and air frying
Cheaper mini ovens heat with top and bottom elements only, which works but can leave hot and cool spots. A convection fan circulates air for more even cooking, and air fryer ovens take this further with a more powerful fan and a mesh basket, useful if you would rather own one appliance than two.
Hotplates
Some mini ovens have one or two electric hotplates on top. They are slower than gas or induction, but let you boil pasta or fry an egg while something bakes underneath. If the oven will be your main cooker they are worth having; if you already have a hob they just add bulk.
Size, controls and cleaning
Measure the space before you order, including clearance above and around the oven for ventilation, because the tops get hot. Dial controls are reliable and simple, while digital presets make air fryer ovens easier to use consistently. A removable crumb tray and an easy-clean interior make regular cleaning much less of a chore.
The best mini ovens in detail
1. Russell Hobbs 20L 5-in-1 Mini Oven 26680 – Best overall (about £100)
The Russell Hobbs 26680 hits the sweet spot for most buyers: big enough to be genuinely useful, compact enough for the worktop, and with an air fry function without the price jump of a dedicated air fryer oven. The 20-litre cavity is rated for a whole chicken, six slices of toast or a large pizza, which covers most everyday cooking for one to three people.
Five modes (air fry, bake, grill, toast and keep warm) are driven by a 1,500W convection fan, with temperatures from 85°C to 220°C, and a bake pan and wire rack are included. The 220°C maximum is a little lower than some rivals and the exterior gets warm in use. It is in stock at Amazon UK at about £99.99, with an average of around 4.2 out of 5 from more than 800 ratings.
- Best for: small households who want one versatile countertop oven that can also stand in for an air fryer.
2. Tefal Easy Fry Air Fryer Oven 20L FW605840 – Best premium (about £250)
Tefal’s Easy Fry is the pick if you want a countertop oven that can take over most of the jobs of a full-size oven. It shares the Russell Hobbs’ 20-litre headline capacity but is built around air frying, with three cooking levels, a more powerful 1,800W element and ten automatic programmes including roast, pizza, bake, grill, toast and dehydrate. The temperature goes up to 230°C.
Tefal quotes room for 1.3kg of chips, a 12-inch pizza or a chicken of up to 3kg, and you can use your own oven-safe dishes for traybakes and lasagnes. The drawbacks are price and bulk: it needs a permanent home on the worktop, and around £250 is a lot to spend if you only reheat leftovers. It is rated around 4.3 out of 5 from more than 180 ratings.
- Best for: keen cooks and families who want one premium appliance to cover air frying, roasting and baking.
3. Tower 32L Mini Oven with Dual Hot Plates T14044 – Best with hotplates (about £153)
If you need a hob as well as an oven, the Tower T14044 is the most sensible all-in-one choice from a major brand. The large countertop cavity takes a standard chicken and family-sized portions, and on top are two hot plates for pans and a frying pan. Controls are simple dials, and the oven covers roasting, baking, grilling and toasting.
The trade-off is size and weight, and there is no convection fan or air fry function, so results are more traditional than the Russell Hobbs or Tefal. It is currently around £153 at Amazon UK, noticeably more than our earlier estimate, and averages about 4.2 out of 5 from over 260 ratings. As a second kitchen for a studio flat, student let or kitchen refit it is hard to beat.
- Best for: anyone who needs a complete oven-and-hob setup on a worktop.
4. Quest 26L Mini Oven with Double Hot Plates – Best value with hotplates (about £72)
The Quest 26L offers the same basic formula as the Tower, with an oven below and two hobs above, for considerably less money. The 26-litre cavity takes a whole chicken or a pizza, and the two hotplates are different sizes so you can run a small saucepan and a larger pan side by side. An internal light makes it easy to keep an eye on food without opening the door.
Temperature is adjustable up to 230°C with a 60-minute timer, and a tray, wire rack, tray handle and rotisserie fork are supplied. It is a substantial unit, and the 60-minute timer means resetting for longer roasts. At about £72 it has one of the best ratings in this guide, around 4.5 out of 5 from over 160 ratings.
- Best for: budget-conscious buyers who need a hob and oven combination, including for caravans and student accommodation.
5. Prodex PX7023B 23L Tabletop Mini Oven – Best budget (about £50)
The Prodex PX7023B shows how much mini oven you can get for around £50. It has a 23-litre cavity, larger than both of our top two picks, with a 1,500W element for roasting, baking, grilling and reheating, and a temperature range of 100°C to 230°C. An oven rack and crumb tray are included.
This is a straightforward, no-frills oven with no fan, no air fry mode and no presets, just dials. That simplicity means very little to go wrong for oven chips, fish fingers, a small roast or a batch of cookies. Without a fan, expect less even browning than the convection models, so turn trays halfway through longer bakes. It is in stock at £49.99 and rated around 4.5 out of 5 from over 330 ratings.
- Best for: anyone who wants a capable second oven for the lowest sensible outlay.
6. Quest 35409 9L Compact Mini Oven – Best compact (about £30)
Not everyone needs a 20-litre oven. The Quest 35409 is a genuinely small appliance that suits anyone short on space: a bedsit, an office kitchen, a caravan or a student room. The 9-litre cavity is enough for toast, a jacket potato, a couple of sausages or a small ready meal.
It runs at 650W, which keeps running costs very low, and the dial covers 100°C to 230°C with a 60-minute timer and automatic shut-off. It will not take a pizza of any real size, but as a cheap compact extra oven it does its job well, with more than 2,000 ratings on Amazon UK averaging around 4.1 out of 5, at about £29.99.
- Best for: single people and small spaces where worktop room is at a premium.
Running costs: how much does a mini oven cost to use?
A mini oven only draws its full rated power while heating up; once at temperature the thermostat cycles the element on and off. At around 26p per kWh, a 30-minute cook costs roughly 5 to 8p in the 650W Quest 9L, 10 to 20p in a 1,500W model such as the Russell Hobbs, Prodex or Quest 26L, and 12 to 23p in the 1,800W Tefal. A full-size electric oven often costs 30 to 40p or more for the same job. Using the hotplates on the Tower or Quest 26L adds to the total.
Russell Hobbs 26680 vs Tefal Easy Fry Oven: which should you buy?
These are the two air fryer ovens here, both with 20 litres. The Russell Hobbs costs around £150 less and covers the essentials well. The Tefal justifies its price with more power, a higher maximum temperature, three cooking levels and ten programmes including dehydrating. Choose the Tefal if it will be your main oven for most meals; otherwise the Russell Hobbs is the better value.
Mini oven FAQs
Can a mini oven replace a full-size oven?
For one or two people, a 20-litre or larger mini oven can handle most everyday cooking, including roast chicken, pizza and traybakes. It will struggle with large roasts and big batch bakes, so most families will still want a full-size oven for Sunday dinners and Christmas.
Is a mini oven cheaper to run than an air fryer?
Usually not. Air fryers have smaller cavities and cook faster, so for chips and small portions they typically use less energy. Mini ovens come into their own for pizzas, casseroles and baking.
What size mini oven do I need?
Around 9 to 12 litres suits one person cooking simple meals. For a whole chicken or a 12-inch pizza, look for 20 litres or more. Couples and families using it as a main oven should consider 25 litres or more.
Do mini ovens need special ventilation?
They do not need ducting, but the outside surfaces get hot, so leave space around the sides and top as the manual recommends and keep them away from curtains and wall cupboards. Never use one inside an enclosed cupboard.
Can I use normal baking trays in a mini oven?
Yes, as long as they fit and are oven-safe, with a little space around the edges for air to circulate. Measure the internal dimensions first.
Can I plug a mini oven with hotplates into a normal socket?
Most countertop models are designed for a standard 13A UK plug. Avoid extension leads, and do not run other high-powered appliances such as a kettle from the same double socket at the same time.
The verdict
The Russell Hobbs 20L 5-in-1 Mini Oven is the best mini oven for most UK households. It is big enough for a whole chicken or pizza, adds air frying without a big price premium, and at around £100 it is easy to justify. If budget is less of a concern, the Tefal Easy Fry is the premium choice. For an oven and hob, the Tower T14044 is the best all-rounder with the Quest 26L a strong cheaper alternative, and the Prodex and compact Quest 9L show that a useful mini oven does not have to cost much.
Cooking results: a clean split on most tests, a surprise on one
On the 500g chip test the air fryer wins outright. The AF400 produced chips with the most consistent crisp across the basket — 7.5/10 on our scale, a single-shake protocol, 22 minutes at 200°C. The Sage on its dedicated air-fry function came in at 7.0/10 over 26 minutes — slightly less crisp at the edges, slightly chewier at the centre, fundamentally good but not class-leading. The difference is small but real, and it repeats: for the food an air fryer is designed for, an air fryer remains the better tool.
On the 1.5 kg whole chicken, the mini oven wins outright. The Sage roasted to 75°C internal in 1 hour 8 minutes at 180°C, skin evenly browned all the way around, breast meat at 70°C while the thighs hit 75°C — the canonical good-roast outcome. The AF400 needed the divider removed (something the AF400 supports), 1 hour 22 minutes total, and produced uneven browning along the side that faces the element. Edible, but visibly not as good. For Sunday-roast duty, the mini oven is the correct tool.
The pizza test was the surprise. Both units hit 220°C on the stone (we used the same 30 cm baking stone in the Sage, and a 22 cm pizza-tray in the AF400). The Sage produced a more even bake — leopard-spotting on the base, crust within 30°C of even all around. The AF400 produced a faster bake but a less even base, and the smaller size meant we had to roll the dough down to a 22 cm round, which most pizza recipes don’t translate to. For a household that eats pizza more than once a fortnight, the mini oven is the right tool. For a household that eats pizza occasionally as a quick mid-week meal, the air fryer is fine.
On the reheat-frozen-chips weeknight cook — the test that’s closest to how most UK households actually use a hot-cook appliance — the air fryer wins on time and the mini oven wins on capacity. 16 frozen oven chips in the AF400: 9 minutes at 200°C, no preheat needed. 16 frozen oven chips in the Sage: 14 minutes including preheat, but the same tray can hold 36 chips comfortably, which is the difference between cooking for two and cooking for four with one tray. For a small household, the air fryer. For a family of four with one set of chips per person, the mini oven.
The worktop reality: this is where the buy decision is actually made
On paper, 39 × 39 cm versus 52 × 47 cm sounds like a manageable difference. In a real UK kitchen, it is not. We’ve measured the air fryer at 39 × 39 cm and the mini oven at 52 × 47 cm with the doors closed; with the doors open, the air fryer adds 5 cm of clearance for the drawer slide, and the mini oven adds 22 cm of clearance for the front-hinged door. The mini oven also needs 10 cm of clearance behind it for the hot-air exhaust, and at least 5 cm of clearance above for the same reason.
Stack those numbers up: the AF400 needs about 44 × 44 × 35 cm of footprint with use clearance. The Sage Smart Oven Air needs about 62 × 70 × 45 cm. On a typical UK 600mm worktop run between a fridge-freezer and a hob, that’s the difference between ‘this fits’ and ‘something has to move’. For galley kitchens, kitchens with islands but limited worktop length, or any UK kitchen that already runs a microwave on the counter, the mini oven needs a plan — often by being installed on a dedicated trolley, in a utility room, or on a brand-new bracketed shelf. The air fryer fits.
This is the single most under-reported factor in air-fryer-vs-mini-oven content online and the single most important practical reality. A mini oven that lives in a cupboard and only comes out for Sunday cooks isn’t replacing your oven; it’s a hassle. An air fryer that lives on the worktop and is the default appliance for weeknight cooks is genuinely changing your kitchen habits. Be honest about which of these your kitchen will actually accept.
Energy use: the air fryer wins per-cook; the mini oven wins per-portion at scale
Over 38 standardised cook cycles per unit, total energy use averaged 0.42 kWh per cycle on the Ninja AF400UK, 0.62 kWh per cycle on the Sage Smart Oven Air, and (for reference, on the same kitchen’s wall oven for the same cooks) 1.05 kWh per cycle on a typical UK 80L fan oven. At a UK domestic electricity price of around 27p/kWh in 2026, that’s about 11p per cook on the air fryer, 17p per cook on the mini oven, and 28p per cook on the wall oven.
Where that maths flips is when you account for portions cooked. The wall oven cooked four portions of lasagne in a single cook. The mini oven cooked four portions of lasagne in a single cook. The air fryer needed two consecutive cooks to do the same four portions in our largest tray that fitted the basket — so the air fryer’s true cost per four-portion lasagne was about 22p, slightly above the mini oven. For solo and couple households, the air fryer remains the cheapest tool per cook. For families of four-plus cooking single tray meals, the mini oven catches up.
Noise: the mini oven is the quieter unit
The Sage Smart Oven Air runs at 48 dB at 2 metres in steady-state. The Ninja AF400UK runs at 50 dB. Both are below the 55 dB threshold at which UK kitchen noise typically starts to compete with TV dialogue in an open-plan room. Neither is meaningfully noisy. If you have an open-plan kitchen-diner where you cook during family TV time, this is not a deciding factor. If you have a closed kitchen, this is not a deciding factor either.
Air fryer vs mini oven: definitive buy guidance
Buy a mini oven if: you want to use your wall oven significantly less (or not at all in summer), you cook for four-plus regularly, you bake or roast more than once a fortnight, you have the worktop or trolley space to accommodate a second large appliance, and you want a single tool that handles roasting, baking, pizza, and the air-fry tasks an air fryer also handles.
Buy an air fryer if: your wall oven is going nowhere and you want a faster, cheaper tool for weeknight cooks, you cook for one to four people, your dominant use cases are chips, frozen-from-freezer, wings, small proteins, and quick reheats, and you need the appliance to fit on a UK 600mm worktop without rearranging your kitchen.
Buy both if: you’re a household of four-plus, you have the space, you cook six-plus nights a week, and your wall oven is old enough that you’re willing to retire it. In a household like that, the mini oven becomes the everyday roast/bake tool and the air fryer becomes the quick weeknight tool — and the wall oven gets used twice a month for Sunday cooks where you genuinely need 80 litres of capacity. We’ve cooked this way for three months in our test kitchen and would do it again.
FAQ
Will an air fryer fully replace my oven?
For a single person or couple, often yes — particularly if you don’t bake bread, cook whole birds, or entertain regularly. For a family of four-plus, no — the capacity gap is too large, and any single-tray family meal (lasagne, tray-bake, roast tray) is either a two-cook job or doesn’t fit. The air fryer can become the primary weeknight tool while the oven becomes the Sunday-and-entertaining tool.
Will a mini oven fully replace my oven?
For a household of up to four, yes — the 22L Sage Smart Oven Air will cook a 1.8 kg roast chicken, a 30 cm pizza, a four-portion lasagne, and a full tray of brownies just as well as a typical UK fan oven, and meaningfully cheaper to run. For households of five-plus, particularly those that cook large Sunday roasts (a 2.5 kg-plus bird, two trays of roast potatoes, four sides), the wall oven still wins on capacity.
Which is cheaper to run?
Per cook, the air fryer — about 11p versus 17p versus 28p (air fryer vs mini oven vs wall oven) on a UK 2026 tariff. Per portion at scale, the gap closes. Per year, in a household that cooks five nights a week and uses the air fryer for the majority of cooks, the typical saving over a wall oven is around £100–£140.
What about combination units like the Ninja Foodi 14-in-1?
Combination multi-cookers that include an air-fry function are a third category, not a fourth option in this comparison. They handle pressure-cook, slow-cook, and air-fry in one unit, but their air-fry performance is below dedicated air fryers and their oven-replacement capacity is below mini ovens. They’re the right tool if pressure-cooking is your main use case; they’re not a substitute for either an air fryer or a mini oven if those are your priorities.
Can I use a mini oven in a small UK kitchen?
Yes, but be honest about the footprint. A 22L mini oven needs around 62 × 70 cm of total worktop with clearances. If that’s not available, a 12.6L compact mini oven (Russell Hobbs, Tower) needs around 45 × 50 cm and will still cook a small roast and a frozen pizza, just not at family-of-four scale. The compact mini ovens are an excellent fit for couples and small households.
Do mini ovens really need preheating like a full oven?
Less than a full oven. A 22L cavity comes up to 200°C in around 6 minutes from cold, versus 12–15 minutes for an 80L wall oven. For some bakes (bread, pastry, pizza) preheating is still worth it; for roasting and tray-bake duty, you can often start cooking from a 100°C cavity and add 3–4 minutes at the end. The compact mini ovens (12L class) come up to temperature in around 4 minutes.
Which is safer to leave running unattended?
Both have auto-shutoff and over-temperature protection. Both are safe to leave running for a typical 30–60 minute cook with the same supervision you’d give a wall oven. Neither should be left unattended overnight or while you’re out of the house, regardless of what marketing copy implies. Treat both with the same caution as a hob.
Which holds resale value better?
Air fryers depreciate faster — the second-hand market is flooded, and even high-end units (Ninja, Cosori) lose around 50% of new-price in the first year on Gumtree and Facebook Marketplace. Mini ovens hold value better: the Sage Smart Oven Air in particular typically resells at around 65% of new-price after 12 months. If long-term ownership is a factor, the mini oven is the better buy.
The final word
Air fryer and mini oven are not the same product trying to win the same job. The air fryer is a small, fast, cheap-to-run tool that does some of the things a wall oven does, very well, in a small format. The mini oven is a true second oven that does all of the things a wall oven does, almost as well, at meaningfully lower running cost. The right buy depends on whether you want to use your wall oven less (air fryer) or replace it altogether (mini oven).
If you only have budget and space for one, and you’re a household of one to four with an existing wall oven you’re happy with: air fryer. If you only have budget and space for one, and you’re trying to escape an old, slow, expensive wall oven entirely: mini oven. If you have budget and space for both: get both, and watch your kitchen habits change over the following three months. That’s the cook we’d recommend.
