There is no doubt that air fryers have become popular in Denmark. With growing demand, questions naturally arise too. One of the most frequently asked questions is: "can an air fryer replace an oven?"
There is no clear-cut answer to this, but in many cases an air fryer is preferable to an oven. In this blog post, we do our best to answer the question and provide a range of examples of when an air fryer can replace an oven.
What is an air fryer?
If the word "air fryer" is new to you, here is a brief explanation. An air fryer is a kitchen appliance that uses hot air to cook food. It works by circulating hot air around the food, allowing it to cook quickly and evenly with very little oil or fat. You can see an air fryer here.
What is the difference between an air fryer and an oven?
The biggest difference between an air fryer and an oven is the way they cook food. An oven uses a more traditional cooking method, where heat spreads evenly throughout the cavity and cooks the food from all sides. An air fryer, on the other hand, works by circulating hot air around the food so it cooks quickly and evenly with very little oil or fat.
Another major difference between an oven and an air fryer is the heating time. Air fryers are popular because they usually heat up faster than traditional ovens. An air fryer is almost fully heated as soon as you switch it on, whereas an oven can take up to 25 minutes to heat up. This also means you can save money on electricity with an air fryer, as you use the kitchen appliance for less time.
Air fryers and ovens also differ in size. Air fryers are generally smaller than traditional ovens, making them better suited to preparing smaller meals. Air fryers are also portable and easy to store, whereas ovens are usually built into kitchen units and cannot be moved.
When can an air fryer replace an oven?
An air fryer can replace an oven in many cases. There are almost no limits to what you can make in an air fryer rather than an oven, such as chips, vegetables, muffins, bread rolls and much more. We have written the blog post "10 things you didn't know you could make with an air fryer", which you can read by clicking here. The blog post gives you an idea of how many possibilities there are for replacing an air fryer with an oven.
The biggest advantage of using an air fryer instead of an oven is that it cooks faster and uses less energy than a conventional oven. These energy savings mean you can save money, as air fryers are more economical than ovens.

As most air fryers typically come in sizes of 4-8 litres, there are some natural limitations if you need to cook for many people. It is also difficult to cook several dishes at the same time in an air fryer, as food sometimes needs to be stacked due to a lack of space. An air fryer is therefore a disadvantage if you need to cook large quantities of food. Conversely, an oven is a disadvantage if you need to heat it up fully even though you are only cooking a few items.
