An air fryer is a small oven with a strong fan, so it suits small, crisp meals; an oven suits crowds, bakes and big roasts. Pick what you are cooking and how many portions, and see which fits.
Neither makes food healthier by itself. General information, not medical advice.
An air fryer is a small oven with a strong fan. It heats less space, so it is quick for small amounts of food and uses less energy for them. An oven holds much more and bakes things an air fryer cannot. Neither one makes food healthier on its own: calories come from the food and the oil you add, not from the machine.
So the useful question is not "which is better?" but "which fits this meal?" Tell the picker what you are cooking and for how many people.
An air fryer cooks by blowing hot air around food in a small chamber. A small space warms up quickly and needs little energy, which is why one published UK comparison put a 600 g chicken breast at roughly a third cheaper in an air fryer than in an electric oven. The same source says the oven can be the better value when you cook for a group, because it cooks a lot in one go.
Running costs depend on your energy prices, your appliances and how full they are, so treat any figure as an example and not a promise.
Not by itself. Both use dry heat, and both need only a spoonful of oil for most foods. Our air fryer oil guide shows how much oil actually changes the calories. One thing worth knowing is that starchy foods such as potatoes and bread form a substance called acrylamide when they brown at high heat. Food safety bodies advise aiming for golden rather than dark brown, and they do not find that air fryers clearly beat ovens on this, so watching the colour matters more than the machine.
Whichever you use, check that meat is cooked through; our safe temperature guide lists the numbers.
Air fryer for small, crisp meals. Oven for crowds, bakes and big roasts. Many kitchens are happiest with both.
An oven bakes bread, cakes and lasagne, holds large roasts, and cooks several trays at once. If you cook for four or more most nights, or you bake, the oven is the tool to rely on. An air fryer is an extra, not a replacement, unless your cooking is mostly for one or two people.
If you have a medical condition, are pregnant or breastfeeding, have or had an eating disorder, or take medication, talk to a doctor or dietitian before changing how you eat. This guide is general information, not medical advice.

A compact single basket for one or two people cooking small, crisp meals, which is where an air fryer beats the oven. You cook in rounds if you feed more.
A bigger basket holds a family portion or a small whole chicken in one go, so you reach for the oven less often.
Two stacked baskets cook a main and a side at once, which suits larger households that want to use the oven less.
