Air Fryer Comparisons
Should you use the air fryer, the oven, the microwave or a deep fryer? And which type of air fryer suits you? Here’s how they compare on results, speed and UK running costs β so you can pick the right tool for each job.
Quick Answer: Air Fryer, Oven, Microwave or Deep Fryer?
Use the air fryer for anything you want crisp in small to medium quantities β chips, chicken, roast veg, frozen food and reheated leftovers. It’s usually faster than the oven and, for a typical UK meal, costs around a third as much to run. Use the oven for large batches and big joints, the microwave for soups, rice and sauces, and a deep fryer only if you regularly cook wet-battered food.
How the Appliances Compare
| Air fryer | Conventional oven | Microwave | Deep fryer | |
|---|---|---|---|---|
| Best for | Crispy food in smallβmedium amounts | Large batches, joints, baking trays | Soups, rice, sauces, fast reheating | Wet batters, large fried batches |
| Crispiness | Very good | Good, slower | Poor β food goes soft | Excellent |
| Preheat | About 3 mins | 10β15 mins | None | Several minutes to heat the oil |
| Oil needed | Little or none | Some | None | Litres |
| Typical meal cost (UK) | About 15p | About 45p | Low for small portions | Plus the cost of the oil |
| Clean-up | Basket and drawer | Trays and oven | Minimal | Oil disposal and a greasy unit |
Running costs are based on our worked example at the OctoberβDecember 2026 Ofgem price cap. See the full maths in Air Fryer vs Oven: Real UK Running Costs.
Air Fryer vs Oven
An air fryer heats a much smaller space with a powerful fan, so it preheats in minutes and usually cooks faster. That’s why a typical meal costs roughly a third as much β often a 25β30p saving each time. The oven still makes sense when you’re cooking for a crowd, roasting a large joint or filling several trays at once, because you’d otherwise be cooking in batches.

Air Fryer vs Microwave
For reheating, it depends on the food. The air fryer brings back crispness to pizza, chips, fried chicken and pastry; the microwave makes those soggy but is far quicker for soups, stews, rice and anything with a lot of liquid. Many kitchens use both. Read Air Fryer vs Microwave: Which Should You Actually Use? and use the Leftover Reheat Guide for air fryer reheating times.
Air Fryer vs Deep Fryer
An air fryer uses a fraction of the oil, is far easier to clean and removes the risk of a pan of hot oil. A deep fryer still produces the best results with wet batters (like battered fish) and is faster for large quantities. For most households, the air fryer covers nearly everything they used to deep fry. See Air Fryer vs Deep Fryer: What Each Is Actually Better At, and the Oil Usage Calculator to compare oil use for your favourite foods.
Which Type of Air Fryer?
Once you’ve decided an air fryer is right for you, the main choices are size, basket vs oven-style, and single vs dual-zone. Our Best Air Fryers buying guide covers each in detail with a size guide and budget table. In short:
- 1β2 people: a 2β4L single basket.
- 3β4 people: 5β7L, or a dual-zone model to cook a main and a side together.
- 5+ people or batch cooking: 8L+ dual-zone or an oven-style air fryer with racks.
We compare by size, type and features rather than ranking brands. Ninja, Cosori, Tower, Philips, Salter and supermarket own brands are all widely sold in the UK β decide what size and type you need first, then compare models at your budget.
Frequently Asked Questions
Is an air fryer cheaper to run than an oven?
Yes, for most meals. At current UK prices our worked example puts a typical air fryer meal at about 15p against around 45p in a conventional oven.
Can an air fryer replace an oven?
For many smaller households it can handle most everyday cooking. You’ll still want an oven for large roasts, big batch bakes and cooking for a crowd.
Is an air fryer healthier than a deep fryer?
It uses far less oil, so air-fried versions of fried foods are generally much lower in fat. Our air fryer vs deep fryer comparison looks at where each one wins.
Is an air fryer better than a microwave for reheating?
For crispy foods, yes. For soups, rice and saucy dishes the microwave is quicker and works just as well.
