How Air Fryers Work
An air fryer is a compact countertop appliance that circulates superheated air rapidly around food using a powerful fan and heating element. This creates a crispy outer layer similar to deep-frying but uses little to no oil. The result is food that tastes fried but with significantly less fat, making it a healthier cooking alternative.
What You Can Cook in an Air Fryer
Air fryers are far more versatile than their name suggests. Beyond chips and fried chicken, you can use them for:
- Roasting vegetables (sweet potatoes, butternut, peppers, maize)
- Cooking meat (chicken wings, drumsticks, pork chops, sausages)
- Baking (small cakes, muffins, bread rolls)
- Reheating leftovers (makes food crispy again instead of soggy like a microwave)
- Grilling fish and seafood
- Toasting and dehydrating snacks
Types of Air Fryers
Basket Air Fryers
The most common design. Food goes in a pull-out basket and hot air circulates around it. Available in capacities from 2 to 8 litres. Basket models are straightforward to use and clean. For a family of 3-4, a 4 to 5-litre basket is a practical size.
Oven-Style Air Fryers
Resemble a mini oven with a front-opening door, shelves, and racks. They offer more cooking space and can cook on multiple levels simultaneously. Oven-style units often include rotisserie, dehydrating, and toasting functions. They take up more counter space but replace several appliances.
Dual Basket Air Fryers
Feature two separate baskets that can cook different foods at different temperatures simultaneously. Useful for preparing a complete meal -- for example, chips in one basket and chicken in the other -- finishing at the same time.
What to Consider When Buying
- Capacity -- 2-3 litres for 1-2 people, 4-5 litres for a family of 3-4, and 6+ litres for larger families or batch cooking.
- Power -- most air fryers range from 800W to 2,000W. Higher wattage heats faster and cooks more evenly. For the larger models, 1,500W or more is recommended.
- Temperature range -- a range of 80 to 200 degrees Celsius covers most recipes. Some models go higher for extra crispiness.
- Timer -- essential for preventing overcooking. A timer with auto-shutoff and an audible alert is standard on most models.
- Non-stick coating -- makes cleaning much easier. Check that the coating is PFOA-free for food safety.
- Dishwasher-safe parts -- baskets, trays, and racks that go in the dishwasher save time on cleanup.
Tips for Best Results
- Do not overcrowd the basket. Leave space between pieces for air to circulate, or the food will steam instead of crisp.
- Shake the basket or flip food halfway through cooking for even browning.
- A light spray of oil on food that is not naturally fatty produces a better golden finish.
- Preheat the air fryer for 3 to 5 minutes before adding food for crispier results.
- Use perforated parchment liners (air fryer-specific) to prevent sticking and make cleanup easier. Do not use regular parchment that blocks airflow holes.
