Air fryers have become one of the most popular kitchen appliances worldwide—and for good reason. They allow you to prepare crispy dishes with up to 80% less oil, in less time than a conventional oven. In this guide, we explain everything you need to know: what it is, how it works, how to use it, how to clean it, and what foods you can prepare with it.
What is an air fryer?
A air fryer (also called Fryer without oil ou air fryerA food processor is a household appliance that cooks food using a... high-speed circulation of hot airThis process, called rapid convection, creates a golden, crispy crust on the outside—similar to traditional frying—but without submerging the food in oil.
In a single device you can frying, baking, grilling, toasting and dehydrating It's ideal for those who want to eat healthier without sacrificing flavor and texture.
How does an air fryer work?
Inside an air fryer there is a heating element (heating element) and a powerful fan. When you turn on the appliance, the fan circulates hot air at high speed around the food placed in the basket. This constant flow of heat:
✅ Cooks food evenly on all sides.
✅ Removes moisture from the surface, creating a crispy texture.
✅ Reduces cooking time compared to a traditional oven.
✅ No need to soak in oil — a light brushing is enough for most recipes.
The result is similar to traditional frying, but with much less fat and without the intense smells of hot oil.

What can I cook in an air fryer?
An air fryer is much more versatile than its name suggests. You can prepare:
Appetizers and snacks French fries, sweet potatoes, cheese bread, empanadas, spring rolls, nuggets, chicken croquettes.
Meat and poultry Chicken (whole or in pieces), chops, hamburgers, sausages, beef.
Fish and seafood Breaded fish, shrimp, squid, tuna steaks.
Vegetables Broccoli, zucchini, eggplant, corn, onion, mushrooms.
Desserts and bakery — Cakes, donuts, croissants, cookies, caramelized bananas.
⚠️ What doesn't work well: Foods with a liquid consistency (such as very wet tempura) and very large amounts of liquid in the basket. The air fryer is not a substitute for a frying pan for stir-fries or stews.
How to Use an Air Fryer — Step by Step
1. Turn on and preheat (optional but recommended)
Some models require preheating for 2–3 minutes before adding food. Consult your model's manual.
2. Prepare the food.
Cut into uniform pieces to ensure even cooking. For extra crispiness, lightly brush with a drizzle of olive oil or cooking spray.
3. Place in the basket without overlapping.
This is the most common mistake. Food needs space for air to circulate. If you overlap them, the result will be soggy instead of crispy. Cook in two batches if necessary.
4. Set the temperature and time.
Each food has its ideal temperature. Quick guide:
🍟 French fries — 180°C, 20–25 min
🍗 Chicken (pieces) — 190°C, 20–25 min
🐟 Breaded fish — 180°C, 12–15 min
🥦 Vegetables — 180°C, 10–15 min
🍔 Hamburger — 190°C, 10–12 min
5. Shake or turn halfway through the cooking time.
Halfway through cooking, remove the basket and shake the food (or turn it over with tongs). This ensures even crispness on all sides.
6. Check before serving.
Cooking times are indicative — they may vary depending on the type of food and the quantity. Always check that it is cooked thoroughly before serving.
How to Clean an Air Fryer
Regular cleaning is essential to maintain performance and prevent smoke during cooking.
After each use:
1. Turn off and let cool completely (at least 30 minutes).
2. Remove the basket and the inner tray.
3. Wash with hot water, mild detergent, and a soft sponge. Never use metal scouring pads—they will damage the non-stick coating.
4. Most baskets are dishwasher safe — check the manual.
5. Clean the inside of the appliance with a damp cloth. Never immerse the appliance in water.
Deep cleaning (weekly or bi-weekly):
If there is accumulated grease residue on the heating element, use a soft brush after the appliance has cooled completely. Clean with a damp cloth with a little detergent and dry thoroughly.
Common Mistakes to Avoid
❌ Stack the food items in the basket. — The biggest mistake. The air doesn't circulate, and the food becomes boiled, not crispy.
❌ Do not shake halfway through. The bottom side gets more cooked than the top.
❌ Using too much water or sauce — It creates excess steam and softens the food.
❌ Not cleaning regularly — Accumulated grease residue causes smoke and bad odor.
❌ Do not use metal utensils in the basket. — They scratch the non-stick coating. Use silicone or wood.
FAQ
Is an air fryer really healthier?
Yes. Studies show that air frying can reduce the fat content of foods by 70% to 80% compared to traditional frying. This means fewer calories per meal—without sacrificing flavor.
Do you need oil to use an air fryer?
It's not mandatory. For foods that already contain natural fat (chicken with skin, hamburgers), there's no need to add oil. For vegetables or breaded foods, a thin drizzle of olive oil spray enhances crispness.
What is the ideal size for an air fryer?
For 1–2 people: 2 to 3 liters. For families of 3–4 people: 4 to 5 liters. For larger families: 6 liters or more.
Does it consume a lot of energy?
Less than a traditional electric oven. A 1400W–1800W air fryer heats up much faster and cooks in less time, resulting in lower overall energy consumption.
Is it suitable for keto or low-carb diets?
Perfect. You can prepare meats, eggs, vegetables, and low-carb snacks quickly and deliciously, without adding extra fat.
Can I use aluminum foil or parchment paper in the basket?
Yes, but be careful. Perforated parchment paper (specifically for air fryers) is the best option — it makes cleaning easier and doesn't block air circulation. Aluminum foil can be used, but never completely cover the bottom of the basket.
