Fourteen types of vegetables, each with a time and a temperature, the chart that should have come with the machine. The biggest problem with the air fryer isn't the technology, but that nobody knows how long broccoli takes in it. These times are calibrated for 1 cm pieces and a half-filled basket, and they work across all models.
Why this works
The cooking time of vegetables depends on two factors: water content and thickness. Water-rich vegetables like zucchini or mushrooms must first lose their water before they can brown, which is why they need high temperature and little time, otherwise they fall apart while still steaming. Dense root vegetables like carrots or beets have little water and a lot of structure; they need time at medium temperature so the heat reaches the center before the surface burns. These two factors result in the three groups in the chart. And because an air fryer circulates air at around 20 km/h, it dries out surfaces extremely quickly, so one tablespoon of oil per 500 g is not a question of calories, but prevents the edges from becoming leathery.
Step-by-step instructions
- 1
Cut evenly
Cut all of one type of vegetable to the same size, this is more important than the exact size itself. A cube of double thickness takes about double the time, and uneven pieces are never done at the same time. The specifications in the chart apply to the dimensions mentioned there.
- 2
Oil and season
Toss the vegetables with one tablespoon of oil per 500 g in a bowl until everything shines. An air fryer moves the air very quickly and dries out surfaces correspondingly fast, without oil the edges become leathery instead of crispy. Add salt only after cooking, except for root vegetables.
- 3
Fill basket halfway
Fill the basket halfway at most. This is the most common source of error by far: in a full basket, the air cannot get between the pieces, the steam gets trapped, and the vegetables steam instead of roasting. It is better to do two batches.

Cook and shake once
Cook according to the chart and give the basket a vigorous shake halfway through. The times are guidelines for a half-filled basket in a preheated machine, check two minutes early the first time, every machine is slightly different.
Our best tips
- Fill the basket halfway at most. This is the difference between roasting and steaming, and it is bigger than any difference between two machines.
- Mix by groups, not randomly. Broccoli and potatoes together result in either raw potatoes or burnt broccoli, anything within one row of the chart goes together.
- Preheating is worth it, three minutes are enough. A cold machine cooks for the first few minutes instead of browning, and exactly those minutes are missing at the end.
Tasty variations
With Parmesan crust
In the last three minutes, sprinkle 40 g of grated Parmesan over broccoli or cauliflower. It melts and becomes crispy, applied earlier it burns in the airflow.
As a meal prep base
Cook two types from the same time group together and refrigerate for three days. Cold in a salad or briefly reheated as a side dish, roasted vegetables hold up much better than steamed ones.

per serving
Calculated from the ingredients – how we do it
We add up reference values for every ingredient and divide by the number of servings. These assumptions are baked in:
- Reference values per 100 g – for the raw ingredient, exactly as listed.
- Tinned goods count at drained weight, bone-in meat at purchase weight: you eat about 70 per cent of a chicken thigh and leave the rest.
- Water evaporates as you cook. The energy stays in the pot, the weight does not – so the figure is per serving, not per 100 g of finished dish.
- Anything listed without a quantity – “salt and pepper” – is not counted.
A guide value, not a lab measurement: no two onions weigh the same, and fat content varies from pack to pack.
Frequently asked questions
Do the times apply to every machine?
As a guideline, yes. Machines differ in basket size and air speed, and small models with high airflow are usually two minutes faster. Check two minutes before the end the first time, from then on you know your machine.
Can I cook multiple types of vegetables together?
Within one time group, no problem. Across groups, only if you add them staggered: potatoes get a ten-minute head start, then the broccoli is added. Everything at once always results in a bad compromise.
Why aren't my vegetables browning?
Three causes, in this order: basket too full, too little oil, temperature too low. The full basket is by far the most common, steam that cannot escape keeps the surface temperature at 100 degrees, and browning only begins at around 140.
