Air Fryer vs Oven for Chips: Taste, Cost and Time Compared
Chips are the dish that started the air fryer craze, and they are the fairest way to settle the debate. The honest answer is that it depends on how many you are cooking. For a portion or two, the air fryer is faster and cheaper. For a family sized batch, the oven pulls ahead. Here is how they compare on the three things that matter most.
| For two portions of chips | Air fryer | Oven |
|---|---|---|
| Cooking time | About 23 minutes, little or no preheat | About 33 minutes, preheat included |
| Energy used | Around 0.29 kWh | Around 0.86 kWh |
| Cost | About 7p | About 23p |
| Taste and texture | Crisp with little oil, can undercook on the base | Crisp and even when spread out, scored marginally higher |
| Capacity | Two to three portions per batch | Full trays, several portions at once |
| Best for | One or two portions, speed, low cost | Families and cooking other dishes at the same time |
Time: the air fryer wins for small portions
An air fryer is a compact fan oven, so it reaches temperature in moments and rarely needs a separate preheat. That is where most of its speed comes from. In Which?’s test, two portions of chips took about 23 minutes in the air fryer against about 33 minutes in the oven, with the oven figure including its preheat.
The picture changes with quantity. An air fryer can only hold so much, so feeding several people means cooking two or three batches back to back, and that quickly adds up. An oven heats a large tray of chips in a single run, so once you are cooking for the whole table it can finish the lot in less total time. If a slow preheat is your sticking point, our guide on why an oven takes so long to heat up is worth a look, as a healthy modern oven should be up to temperature within minutes.
Cost: cheaper by the portion, closer by the batch
Running cost comes down to wattage multiplied by time. An air fryer draws less power and runs for less time on a small load, so it costs noticeably less. In the same Which? test, those two portions of chips cost about 7p in the air fryer and about 23p in the oven, with the air fryer using roughly a third of the energy.
That advantage holds only while portions are small. Once you would need several air fryer batches to match one oven tray, the oven can work out the same or cheaper overall, because it cooks far more for each unit of energy. The other cost to remember is the air fryer itself, which is an extra purchase a built in oven does not require.

Taste and texture: closer than you might expect
Air fryers have a reputation for crispier chips, and the intense circulating air does give a good crunch with very little oil. In controlled testing, though, the gap is smaller than the hype suggests. Which? found the two methods produced similar chips, and the oven actually scored marginally higher for consistency, while the air fryer left a few chips on the base undercooked.
The real lesson is that technique matters more than the appliance. Both crisp beautifully in a single layer and both cook unevenly when crowded. An air fryer needs a shake or two during cooking, and oven chips need spreading out and turning. Get those right and the difference on the plate is small.
Capacity: the deciding factor
This is what settles most kitchens. Air fryer baskets are small, and manufacturers often recommend filling them only halfway, which works out at roughly two to three portions of chips. That is perfect for one or two people, but limiting if you are cooking for a family or want chips alongside something else in the same appliance.
An oven gives you the room to cook a large tray of chips, or chips on one shelf and another dish on the next. When you are feeding several people, that space is exactly what makes the oven the more practical and often the more economical choice.
How to get the best chips from each
In an air fryer
- Cook around 190 to 200 degrees
- Keep to a single layer and do not exceed the fill line
- Shake the basket once or twice during cooking
- Allow roughly 15 to 25 minutes depending on the chip
In an oven
- Preheat to 200 to 220 degrees
- Spread on a hot tray in a single layer so they crisp rather than steam
- Turn once halfway through
- Use the fan or air fry setting for extra crispness
The middle ground: an oven with air fry
You do not always have to choose. Many modern ovens include an air fry or strong fan setting that circulates hot air for the same crisping effect, with the capacity of a full oven behind it. Our guide on air fry mode in ovens explains how it works and when it is worth using, and how a fan oven works covers the airflow both appliances rely on.
The verdict
- For one or two portions, the air fryer is faster and clearly cheaper, costing around a third of the oven for a small batch of chips.
- Taste is closer than the hype suggests. In testing the results were similar, with the oven marginally ahead on consistency.
- Capacity is the deciding factor. The air fryer manages two to three portions, while the oven handles a full tray.
- For families or cooking several things at once, the oven is more practical and can be cheaper overall.
- An oven with an air fry setting offers the best of both, crisp chips with full capacity.
Frequently asked questions
For a small portion, clearly yes. Testing found two portions cost about 7p in an air fryer against about 23p in an oven. The gap narrows once you cook enough to need several air fryer batches, where the oven can be cheaper overall.
They crisp well with very little oil, but in controlled tests the results were close to the oven, which even edged ahead on consistency. Spreading the chips out and turning or shaking them matters more than which appliance you use.
For a small portion, yes, mainly because there is little or no preheat. An oven cooks a much larger quantity in one go, so for a big batch it can be quicker overall than running several air fryer loads.
Usually two to three portions per batch, as makers often advise filling the basket only halfway. For more than that you cook in batches or switch to the oven.
Yes. Many ovens have an air fry or strong fan setting that circulates hot air for similar crisping, with far more room than an air fryer basket. A preheated tray and a single layer help too.
The cooking times, energy use and costs for chips come from the independent air fryer vs oven test by Which?, the UK consumer body.
