Air Fryer Uses: What an Air Fryer Is Really For (7 Jobs)
Quick answer
An air fryer is used to cook food with fast-moving hot air instead of a pot of oil. Frying is only one of its jobs. The control panel on an Instant Vortex names seven: air fry, roast, bake, grill, reheat, dehydrate and proof dough. Together they run from 32 °C for rising dough to 205 °C for chips. It is closer to a small fan oven than to a fryer.
What is an air fryer actually used for?
Most people buy one thinking it is a fryer without oil. That is one job out of seven.
The fastest way to see what the machine is really for is to read its own control panel. Instant lists seven named programmes on the Vortex Air Fryer Oven, each with its own temperature range. Here they are exactly as the manual prints them.
| Job | Default | Lowest | Highest | What it is for |
|---|---|---|---|---|
| Air Fry | 205 °C | 82 °C | 205 °C | Chips, nuggets, wings, cauliflower bites |
| Roast | 193 °C | 82 °C | 205 °C | Poultry, vegetables, potatoes |
| Bake | 185 °C | 82 °C | 205 °C | Breads, cakes, pastries, buns |
| Grill | 205 °C | 205 °C | 205 °C | Top-down heat, melting cheese |
| Dehydrate | 49 °C | 35 °C | 79 °C | Dried fruit, dried vegetables |
| Reheat | 138 °C | 49 °C | 182 °C | Leftover fries and pizza |
| Proof | 32 °C | 32 °C | 42 °C | Letting yeast dough rise |
Look at the spread. The lowest setting is 32 °C, which is barely warm. The highest is 205 °C. No fryer needs that range. An oven does.
If you are still at the earlier question of how the thing works at all, we answer that separately in What is an air fryer and is it worth it.
The 7 jobs, one at a time
1. Air frying (82 °C – 205 °C)
Hot air moves fast around the food so the outside dries and crisps. This is the job the machine is named after. Instant lists fries, cauliflower bites, wings and nuggets for it. In an Indian kitchen it is the one that turns frozen samosas, aloo tikki and bhindi crisp without a kadai of oil.
2. Roasting (82 °C – 205 °C)
Instant describes roasting as giving food "a deliciously tender inside and browned outside". Whole chicken pieces, paneer cubes, gobi, sweet potato and bell peppers all sit here. Philips puts chicken drumsticks at 180 °C for 18–21 minutes and mixed vegetables at 180 °C for 15–20 minutes.
3. Baking (82 °C – 205 °C)
Instant calls this using "the air fryer as your own 'mini oven'". Philips backs it up with real numbers: muffins at 160 °C for 15–17 minutes, cake at 160 °C for 35–45 minutes, homemade bread at 160 °C for 40–50 minutes. For cake and bread Philips says to use the baking accessory, and to keep bread dough flat so it does not touch the heating element as it rises.
4. Grilling (205 °C)
Instant says grilling "cooks using direct top-down heating" and gives melted cheese as the example. It runs at one fixed temperature. This is the setting for browning a top, not for cooking something through.
5. Reheating (49 °C – 182 °C)
Instant's words: "Bring the crisp and crunch back to leftover fries or pizza, in just a few minutes." This is the job most Indian homes use every single day and never think of as a feature. Last night's pakoras go back to crisp instead of going soft in a microwave.
6. Dehydrating (35 °C – 79 °C)
"Dehydrating uses low heat over a long period of time to safely dry out food items, like dried fruit, jerky and dried veggies," says Instant. It runs for up to 72 hours. This is where dried methi, curry leaves, mango slices and homemade banana chips come from.
7. Proofing dough (32 °C – 42 °C)
Instant: "Allow your dough to rest and rise, and let the yeast do its job for airy loaves of bread." It holds a warm, steady 32–42 °C for 30 to 40 minutes. In a cold north Indian winter that is the difference between dough that rises and dough that sulks.
Seven jobs, one box, one plug point. That is the real answer to what an air fryer is for. If you want the dish-by-dish version instead, we keep that in 25 Indian air fryer recipes.
What Philips’ own food table says
Programme names are one thing. Real times and temperatures are another.
The Philips NA220 and NA221 manual sold with Indian air fryers carries a full food table. Philips notes that "these settings are suggestions", because ingredients differ in origin, size, shape and brand. Still, it is the closest thing to an official starting point you will find.
| Food | Amount | Time (min) | Temperature | Philips’ note |
|---|---|---|---|---|
| Thin frozen fries (7×7 mm) | 200–500 g | 14–25 | 180 °C | — |
| Homemade fries (10×10 mm) | 200–500 g | 30–33 | 180 °C | — |
| Frozen chicken nuggets | 200–500 g | 10–20 | 200 °C | — |
| Frozen spring rolls | 200–500 g | 10–20 | 200 °C | — |
| Hamburger (about 150 g) | 1–2 pieces | 12–16 | 150 °C | — |
| Meat loaf | 400–600 g | 35–45 | 150 °C | Use the baking accessory |
| Meat chops without bone (about 190 g) | 1–2 pieces | 16–20 | 200 °C | Shake, turn or stir halfway |
| Chicken drumsticks (about 125 g) | 2–6 pieces | 18–21 | 180 °C | Shake, turn or stir halfway |
| Chicken breast (about 160 g) | 1–4 pieces | 18–21 | 180 °C | — |
| Whole fish (300–400 g) | 1 piece | 23 | 200 °C | — |
| Fish fillet (about 200 g) | 1–3 pieces | 21–23 | 200 °C | — |
| Mixed vegetables, roughly chopped | 200–500 g | 15–20 | 180 °C | Shake, turn or stir halfway |
| Muffins (about 50 g) | 1–7 pieces | 15–17 | 160 °C | — |
| Cake | 400–600 g | 35–45 | 160 °C | Use the baking accessory |
| Pre-baked bread or rolls (about 60 g) | 1–5 pieces | 6–10 | 200 °C | — |
| Homemade bread | 400–600 g | 40–50 | 160 °C | Use the baking accessory. Keep the dough flat |
| Breakfast | 3 eggs, 2 toasts | 10 | 160 °C | Cook the eggs first for 5 minutes, then add the toasts |
Notice what is in that table. Cake. Muffins. Homemade bread. Eggs and toast together as one breakfast setting. A manufacturer does not print baking times for a machine meant only for chips.
Philips also says to shake, turn or stir the food halfway for larger amounts, so the hot air can reach every side.
What an air fryer is NOT used for
This is where most kitchen mistakes happen. Both manuals are blunt about it.
- Anything wet. Philips: "This is an Airfryer that works on hot air. Do not fill the pan with oil, frying fat or any other liquid." So no dal, no curry, no gravy, no batter that pours.
- Oil in the pan. Philips: "Do not fill the pan with oil as this may cause a fire hazard." Instant: "DO NOT pour oil into the cooking container. If needed, spray food."
- Deep frying. Instant states it outright: "DO NOT use this appliance for deep frying foods."
- Light, loose items and loose paper. Philips: "Never use light ingredients or baking paper in the appliance." The fan will lift them onto the heating element.
- An overfilled pan. Philips: "Never put any amount of food that exceeds the maximum level indicated in the pan." Instant warns that overfilling can push food into contact with the element.
- Foil over the accessories. Instant: "DO NOT cover the accessories or any part of the appliance with foil."
Foil is the one people argue about most, because some uses are fine and some are not. We went through it case by case in can you use aluminium foil in an air fryer.
Two more lines worth knowing. Philips asks for at least 10 cm of free space behind, beside and above the machine. Instant asks for 13 cm all round, and says not to run it for more than 60 minutes in any 2-hour window.
Do you have to preheat it?
Almost every article online tells you to preheat for three to five minutes. Your manual may disagree.
The Philips NA220 and NA221 manual says it in four words: "Preheating of the appliance is not necessary." It sits right in the caution box on the Airfrying page.
Other models are built differently. The Instant Vortex has a Preheat button, and its Reheat programme notes that "there's no preheating time" once it starts. So the honest answer is that this is a per-model instruction, not a universal rule.
Read the booklet that came in your box before you follow a blog. That includes this one. The rest of the first-day routine is in how to use an air fryer for the first time.
Is it actually healthier? The honest answer
The oil saving is real, and it is large.
A 2024 study in Frontiers in Nutrition cooked the same potatoes three ways and printed exactly how much oil each method took. The air fryer arm used 2 teaspoons, 10 g, of sunflower oil for every 250 g of potatoes. The deep-fry arm used 500 mL of sunflower oil to cover the same 250 g. The oven arm used the same 10 g as the air fryer.
That is the part you can trust. Now the part the internet gets wrong.
The same study measured acrylamide, the compound that forms when starchy food browns. The result went the other way. The highest level was in the air-fried potatoes at 12.19 ± 7.03 µg/kg, followed by deep frying at 8.94 ± 9.21 µg/kg and oven frying at 7.43 ± 3.75 µg/kg. The authors then add the line that matters: the difference between the cooking methods was not statistically significant.
So the fair reading is that air frying is a low-oil method, not a proven low-acrylamide one. Anyone telling you it cuts acrylamide is going further than this study does.
One thing in the study did work. Soaking the potato strips in water before cooking lowered acrylamide in all three methods, and for deep frying that drop was statistically significant. The European Food Safety Authority says the same: soaking potato slices in water can cut acrylamide in crisps by up to 40 per cent.
Two more practical lines, both from manuals and both about the same thing. Philips says do not fry fresh potatoes above 180 °C, and to make sure food comes out "golden yellow instead of dark or brown". EFSA notes that acrylamide forms above 120 °C in starchy, low-moisture food. Golden, not brown, is the rule.
We dug into that whole question on its own page: is air-fried food safer than deep-fried. And the parts of the machine nobody advertises are in 8 honest air fryer problems.

Air fryer uses in Marathi, Telugu and Bengali
Readers reach this page in more than English. There is no old Indian word for the appliance, so every language simply spells the English name in its own script.
- Marathi — एअर फ्रायरचा वापर, meaning the use of an air fryer. Same seven jobs as the table above.
- Telugu — ఎయిర్ ఫ్రమైయర్ ఉపయోగాలు, meaning air fryer uses.
- Bengali — এয়ার ফ্রায়ারে কি কি রান্না করা যায়, meaning what can be cooked in an air fryer. The Philips food table above is the direct answer.
- Hindi — एयर फ्रायर, used as it is.
Do you even need one?
Be honest about which of the seven jobs you will actually use.
If the answer is reheating and the odd batch of chips, a small model is plenty. If it is baking and roasting for a family, you want capacity, and you are really shopping for a small oven. We compare that choice in what an air fryer costs to run each month in rupees, because running cost surprises more people than the sticker price does.
InstaCuppa does not make an air fryer. If you want one, the honest thing we can do is point you at the air fryer listings on Amazon India and tell you to read the manual before the reviews.
What we do make is for the opposite problem: small, quick cooking for one or two people, where pulling out a full appliance is too much work.

Frequently asked questions
What is the use of an air fryer?
It cooks food with fast-moving hot air instead of a pot of oil. On the Instant Vortex control panel that one machine does seven jobs: air fry, roast, bake, grill, reheat, dehydrate and proof dough. The settings run from 32 °C for dough all the way to 205 °C for frying and grilling.
What is the purpose of an air fryer?
To get a fried texture with a spoon of oil instead of a pan of it. In one peer-reviewed study the air fryer arm used 2 teaspoons (10 g) of sunflower oil per 250 g of potatoes. The deep-fry arm used 500 mL of oil to cover the same potatoes.
What is the function of an air fryer?
A heating element at the top gets hot and a fan pushes that hot air down and around the food. The dry moving air pulls moisture off the surface, so the outside browns and crisps. It is the same idea as a fan oven, in a much smaller box.
Can I cook everything in an air fryer?
No. Philips is direct about it: "This is an Airfryer that works on hot air. Do not fill the pan with oil, frying fat or any other liquid." So no dal, no curry, no gravy. Philips also says "Never use light ingredients or baking paper in the appliance." Instant adds "DO NOT use this appliance for deep frying foods."
Do I need to preheat my air fryer?
Check your own manual. The Philips NA220 and NA221 manual states plainly: "Preheating of the appliance is not necessary." Other models are built differently. The Instant Vortex has a Preheat button, and its Reheat setting says "there's no preheating time".
Is air frying healthier than deep frying?
It uses far less oil, and that part is solid. The health claim beyond oil is weaker than the internet suggests. A 2024 Frontiers in Nutrition study found the highest acrylamide in the air-fried potatoes, not the deep-fried ones, though the difference between methods was not statistically significant.
Can an air fryer replace an oven?
For small batches, often yes. Instant markets its Bake setting as "your own 'mini oven'" and Philips lists cake, muffins and homemade bread in its own food table. The limit is size, not ability. A 4 L drawer holds 400–600 g of cake batter, not a full tray.
What can I NOT put in an air fryer?
Oil, fat or any liquid in the pan. Loose light items such as dry leaves of spinach, which the fan will blow into the element. Baking paper on its own, which Philips bans outright. Foil that covers the accessories, which Instant bans. And food piled above the MAX line in the pan.
