No, air fryers generally use less electricity than a conventional oven for most tasks because they are smaller, heat up much faster, cook food quicker, and don't usually need preheating, leading to significant energy savings, especially for smaller meals. While they use 800-2000 watts, the shorter cooking times mean lower overall energy consumption compared to larger ovens that can use 2000-4000 watts and take longer to heat up and cook.
People are getting rid of air fryers due to small basket sizes limiting family meals, issues with peeling non-stick coatings, difficulty cleaning, safety concerns like melting components, the perception they're just small ovens, limitations on certain foods (like wet batters), and sometimes switching to cheaper, more efficient appliances like halogen ovens. Many find they outgrow basic models, leading to batch cooking, and eventually replace them with larger or different appliances.
Generally speaking, an air fryer is more likely to save money on your energy bill compared to an oven thanks to their typically lower wattage and quicker cooking times. This is especially the case if you are cooking for small groups as dinkier air fryers tend to be more energy efficient than larger models.
Air fryer disadvantages include limited capacity (requiring batch cooking), taking up valuable counter space, a learning curve for even cooking (needing shakes/turns), potential formation of harmful compounds like acrylamide if food is charred, issues with cooking wet batters, and concerns over non-stick coating safety (PTFE). They also can't perfectly replicate deep-fried taste and may be noisy.
Is it cheaper to run an air fryer than an oven? Yes, in most cases it is. Air fryers are generally cheaper to run than ovens because they use less power and cook food faster. While a standard oven might use 2,000–4,000 watts, most air fryers use around 800–2,000 watts and often don't need preheating.
Heating and cooling (HVAC) typically runs up an electric bill the most, often accounting for around 40% of energy usage, followed by water heating, large appliances like refrigerators and clothes dryers, and lighting. The biggest energy drains are systems that change air temperature (furnaces, air conditioners) and appliances that heat water (showers, dishwashers) or run for extended periods (dryers, fridges).
The "air fryer rule of 25" is a guideline for converting conventional oven recipes: reduce the oven temperature by 25°F (or 10-20°C) and decrease the cooking time by about 20-25%, checking for doneness earlier. This rule accounts for the air fryer's faster, more intense circulating heat, ensuring food cooks quickly but doesn't burn, though adjustments are always needed based on the specific food and appliance.
A high-fat food isn't going to be any healthier cooked in an air fryer than any other way. Air frying does have a few drawbacks, such as the possibility of some plastic toxins leaching into the food, depending on the materials used to make it. So, while air fryers are safe to use, don't use them exclusively.
5 Common Mistakes to Avoid When Using an Air Fryer
Yes, you can put tin foil (aluminum foil) in an air fryer for easier cleanup and to prevent sticking, but you must follow important safety rules: never let it touch the heating element, ensure it's weighed down by food to prevent it from flying around, and avoid using it with acidic foods like tomatoes or citrus to prevent chemical reactions and aluminum leaching. Always check your air fryer's manual and make sure the foil doesn't block the air vents for proper circulation.
CAN YOU PUT METAL COOKWARE IN AN AIR FRYER? Cookware that is labeled as oven-safe is usually suitable for use in a range with an air fry feature. Examples of oven-safe metals include cast iron, stainless steel and aluminum.
To bake in an air fryer, reduce the temperature of your recipe by 25°F and reduce the cook time by 20%. For example, cookies baked at 375°F for 10 minutes would be baked in an air fryer at 350°F for 8 minutes. 425°F in an oven would be 400°F in an air fryer, and so on.
Energy Consumption of Various Cooking Appliances
When you compare that to an electric oven, which uses 3.5 kWh per hour and costs $0.58 per hour, air fryers use less than half the energy. While air fryers use a little more electricity than a microwave or pressure cooker, the difference is small.
Air Fryers Reduce Taste Quality
Out of the top three reasons restaurants don't use air fryers, the taste is the leading cause. It has numerous benefits and can cook food efficiently. However, the taste can be subpar compared to other cooking methods available at the commercial level.
It's not just about fat.
There's more to air fryers than calories and crunch. Cooking with less oil also reduces acrylamide, a potentially harmful chemical that forms in starchy foods when they're cooked at high temperatures. “Air frying has been shown to lower acrylamide levels compared to deep frying,” says Dr.
Foodies are switching to healthier halogen ovens that are still small enough to sit on a kitchen worktop but have far cheaper running costs. This £29.89 Daewoo model on Amazon costs as little as 11p to run per 20-minute meal as shoppers who 'don't want to spend money on Ninja' pick it.
But here's the bit I wish I'd known – air fryers aren't always the cheapest option to run. It all depends on what you're cooking and the wattage of your machine. Do the same dish twice in a small 800W air fryer and you could actually spend more than if you'd just used the oven.
The "Air Fryer 20/20 Rule" is a guideline for converting conventional oven recipes, suggesting you reduce the cooking time by 20% and lower the temperature by 20°C (or about 20°F) to account for the air fryer's faster, more intense cooking. While a good starting point, it's essential to monitor your food and potentially shake or flip it halfway through for even cooking, as air fryer models and foods vary, notes this BBC article.
It's only when the food surface is charred or burned that the levels of acrylamide start to take off and exceed safe levels that there is any risk. What does that mean for air-fryer users? As long as you follow the manufacturer's recommendation and don't burn your food, you have absolutely nothing to worry about!
Yes, an air fryer is generally healthier than a microwave because it requires little to no oil for cooking, resulting in lower fat content in your meals. The Duronic AF34 WE double air fryer, for example, uses advanced hot air circulation to cook food evenly and healthily.
Cooking in the oven and cooking in the air fryer will generally end up with food that has the same nutrient profile since an oven and an air fryer use similar heating techniques. In this case, air-frying would not be considered a healthier alternative to baking your food in an oven.
Transfer veggies into frying compartment and fry for 15 to 20 minutes, stirring veggies every 5 to 8 minutes or so. Some veggies might need longer and some will need less – just use your judgment when you open the compartment to stir the veggies. You want the outside to be golden and crispy and the inside to be tender.
Yes, it is worth buying an air fryer for 2 people. Air fryers are efficient, compact, and ideal for preparing quick, healthy meals with minimal oil. They save time and energy, making them a practical choice for couples or small households looking for convenience and versatility in everyday cooking.
