Five mini ovens I'd plug in before turning the main one on this summer
Late June, the kitchen tiles still warm from yesterday, and firing up the main oven for one tray of veg feels mad. Five mini countertop ovens from about £34 up to £114, picked for what actually goes through a real UK kitchen between May and September.
I'm typing this in a top-floor flat with all the windows open and the kettle decisively off. Late June, the kitchen tiles still warm from yesterday, and the thought of putting the proper oven on to roast a tray of veg feels — well, mad. Two hours of 200°C residual heat sitting in a room you also have to eat in is not a summer plan.
So I've been pulling mini countertop ovens out of the catalogue and asking which ones I'd actually plug in instead. Not as a backup. As the appliance you reach for between May and September, when the main one is doing more damage than dinner.
How I picked these
A mini oven on a worktop has to earn its space. The filter is short:
Capacity that matches a real meal. Nine litres handles toast and a single chicken thigh. Twenty fits a pizza. Thirty fits a small roast. Picture the thing you cook most, then add 20%.
A temperature range that goes both directions. Most mini ovens top out at 230°C, which is fine. The thing to check is the floor. Anything that won't drop below 100°C struggles to prove dough or gently reheat.
A timer that actually cuts the power. Not just an alarm. Sixty minutes of auto-off means you can put the laundry on while the fish bakes.
A handle on the tray. Sounds picky, but it's the single best test of whether the engineers have ever cooked anything. If you need a tea towel to drag a hot tray out, the oven is already in the wrong place on the worktop.
Five picks below, roughly £34 up to £114, capacities from 9 to 36 litres. There is no single best one; the right mini oven depends on the kitchen you've got and what you're actually cooking. Each pick is the answer to a different question.
1. The "just enough" pick — 9L Mini Countertop Oven, about £34
This is the one for the single person, the student, or the second-bedroom-turned-office where you'd rather not trek down to the kitchen for a slice of toast. Nine litres sounds tiny because it is — a 750W draw, two rack positions, a tray small enough to look like a doll's house roasting dish. But it does the basics properly: a 100-230°C range, a sixty-minute auto-off, a brushed-steel finish that wipes clean. For the price of three takeaways, it's a sensible bit of kit.
The honest caveat is capacity. You're not feeding two people a proper meal out of this — it's a one-portion oven, full stop. The silver casing also picks up fingerprints in raking light, so if it's going to sit in a sunbeam, plan for a quick wipe-down. For desk-side reheating, a flatmate's room, or the bedsit you swore would be temporary, it earns its plug.
2. The everyday workhorse — 21L Mini Countertop Oven in Grey, about £57
The 21-litre is the size most people end up wanting. It'll take a ten-inch pizza, four slices of toast laid flat, or a tray of roast veg for two. Independent top and bottom heating elements is the spec to notice here — you can pick top-only for grilling, bottom-only for baking, or both for everything else. The little metal handle on the tray sounds trivial and is anything but: means you can pull a tray of crisping chicken out without doing the awkward tea-towel grab.
The caveat is the dial set. There's no remote, no preset programmes, no LED display — just two physical dials and a switch. If you want digital, jump to pick five. But for a backup oven that lives on the worktop and gets used three or four times a week, the analogue feel is honestly a feature, not a bug. Fewer things to go wrong, fewer beeps to silence, no firmware update at 11pm.
3. The hosting upgrade — 30L Mini Electric Oven, about £77
Step up to thirty litres and the calculus shifts. You can fit eight slices of bread, a dozen chicken wings, or a small whole chicken — proper meal territory, not just supplementary. The temperature range is the standout: it drops to 60°C, which is the difference between an oven you can prove dough in and one you can't. Three heating modes, a double-glazed door that genuinely cuts the surface temperature, and the same sensible 60-minute timer. This is the one to buy if the main oven is shared, awkward to reach, or always full of someone else's meal-prep.
The footprint is bigger — you need clear worktop, roughly 50 cm wide, and clear space above for the steam. The brushed-silver look also dates a bit in a cream kitchen. But for the family hosting Sunday lunch in a small flat, or the holiday-let owner who needs a backup that can actually roast something, the £20 jump over the 21L is well worth it.
4. The studio-flat all-in-one — 36L Mini Oven with Dual Hot Plates, about £94
This one earns its own category. A 36-litre oven cavity (big enough for a 12-inch pizza or a small whole chicken) with two electric hot plates built into the top — basically a tabletop cooker for any kitchen that doesn't have a built-in hob. Think: a London studio with a kitchenette, a converted garage flat above a takeaway, a static caravan, or that awkward annexe your parents call "the granny flat". 2600W total draw, three rack heights, a black stainless finish that hides smudges better than the silver options. For a kitchen without a proper hob, it's the kit that turns it into a working kitchen.
What you give up is headroom on the circuit: with the oven on full and both rings going, you can trip the breaker on a single 13A spur, so don't have the kettle on at the same time. The hot plates also take a while to come up to temperature — they're not induction-quick. But for less than the price of a decent induction hob on its own, you get hob, oven and grill in one box. It's a proper flat-saver.
5. The splurge — 20L Cream 7-in-1 Mini Oven, about £114
This is the one you buy if the oven is going to live on a visible worktop and you actually want to look at it. The cream-and-chrome retro finish is a proper bit of design — it'd sit just as happily in a Smeg-heavy Wirral kitchen as in a Hackney rental. Seven cooking modes, with fan-assisted air-fry being the one that matters: you genuinely can ditch a separate air fryer and a toaster for this single appliance. The 360° hot air circulation does what it says — chips come out evenly crisp, not pale on one side. A 90-230°C range, so it'll also gently warm croissants without scorching them.
The price is the obvious caveat. At £114 it's twice the workhorse 21L, and you're paying meaningfully for the looks. The 20-litre cavity is also slightly smaller than the 21L pick despite costing more, so don't buy it for capacity. Buy it because you want one nice multi-tool sitting on the worktop instead of three ugly black plastic boxes. For the right kitchen, that trade is sensible.
Plug socket position. Most of these have a 1.25-1.5 m cable. Hold a tape measure to the spot it's going and check it reaches a free socket — not one already being used by the kettle. Mini ovens pull 1500-2600W; sharing a circuit with another high-draw appliance trips breakers.
Clearance above. Steam needs somewhere to go. Don't tuck one under a wall cupboard — you'll warp the cupboard door and shorten the oven's life. Six inches of clear space above the vent is the sensible rule.
Worktop heat. The base does get warm, even with insulated feet. A sheet of slate or a silicone trivet underneath is cheap insurance for a wood or laminate top.
Tray dimensions. If you've already got a favourite roasting tin, check it actually fits before ordering. The 21L picks take a 25 x 20 cm tray; the 30L and 36L will swallow a standard 30 cm tin.
The verdict
If you only buy one and want a sensible all-rounder, get the 21L grey workhorse — it's the size most people end up using and the price is honest. If your kitchen is a kitchenette and you've genuinely got no hob, the 36L combo with hot plates changes what's possible in that space. And if you're going to look at the thing every day on a visible worktop, spend the £114 on the cream 7-in-1; you'll use it more because you'll like seeing it.
