Energy-efficient cooking
Did you know you can save both time and money by changing the way you cook? With energy prices rising, we reveal the cost saving you could make by air frying your food, along with some tips to keep your bills low.
Do air fryers use a lot of electricity?
- You can cook enough burgers for 4 people in your AF400UK or AF451UK in just 12 minutes, for no more than 6p of electricity*
- You can cook 0.5kg of frozen French fries in your AF400UK or AF451UK in just 14 minutes, for only 6p of electricity*
- Air Frying for 20 minutes using an AF400UK or AF451UK only costs 9p of electricity*
- The AF300UK and AF400UK cook up to 75% faster than fan ovens**
Does an air fryer use more electricity than an oven?
You can save up to 75% on your energy bill with Ninja Air Fryers***.
Wondering if it’s cheaper to cook in an air fryer than an oven? The amount of energy used to cook at home will depend on the appliance, foods and the functions selected.
For example, large ovens may be able to cook bigger foods, cook more at once and be well-insulated, while newer appliances may have a broader range of functions and features for reduced cook times.
However, their size may mean more energy is required to get them to temperature and more energy could be lost if access to the food is needed during cooking.
- Plug-in meters allow you to measure the energy consumption of appliances with accessible sockets. Careful use of domestic smart meters may allow you to approximate your oven’s energy use.
Energy Saving Tips
Turn appliances off when not in use
Some appliances may have a standby mode, but this can still use a small amount of energy. To ensure no electricity is being used, turn appliances off at the plug.
Choose an appropriate appliance each time
For maximum efficiency, make sure you select the right appliance for the food type, portion size and length of cooking time needed. For example, if you have a small air fryer or countertop cooker, there’s no need to heat up your whole oven to cook a single portion.
Defrost food before cooking
Defrosting food before cooking can reduce the amount of energy and time required to cook it, as cooking from frozen tends to take longer – although this may not be suitable for all food types, so check packaging carefully.
Frequently Asked Questions
Energy efficient kettle usage
Only boil the amount of water you need: Prevent using energy to boil water you won’t use by only filling the kettle or saucepan with the amount you need - providing it is above the kettle’s ‘minimum fill’ line. Regularly descale your kettle: A build-up of limescale can affect kettle performance, so descale your kettle regularly, especially if you live in a hard water area. Consider a temperature-control kettle: A variable temperature kettle gives you greater control over your water’s final temperature, perfect if you don’t need it at 100 degrees every time. Ninja kettles also offer a ‘hold temp’ feature which keeps you water at your chosen temperature for up to 30 minutes – so there’s no need to reboil.
Energy efficient hob usage
Use a lid on pans: It might sound simple, but remembering to put a lid on your pan stops heat escaping during cooking and speeds up cooking time. Select the best hob ring for your pan: Using an appropriately sized hob ring for your cookware helps to avoid wasting heat and use only the energy you need. Boil water in a kettle: Although it varies based on the type of energy your hob uses, it can be cheaper to boil water in a modern, energy efficient kettle, rather than on the hob, as long as you only boil the amount you need.
Energy efficient oven usage
Keep the oven door closed while cooking:
Opening your oven while cooking allows heat to escape, lowering the internal temperature. It then takes more energy for the oven to heat back up to your selected temperature.
Utilise carry-over cooking: For some recipes, you can turn the oven off a few minutes early and leave the food inside to continue cooking with the residual heat. Baking cakes and bread require precision cooking, but other recipes allow more leeway. Always ensure food is cooked to a food-safe temperature before eating.
Cook in bulk or batches: Batch cooking helps to make the most of the energy you have already used to heat up your appliance, by cooking more than one portion and saving it for later. One-pot meals such as cottage pies, curries, stews and lasagne are great for cooking in bulk and tend to freeze well.
How much energy do other Ninja appliances use?
The wattage for all Ninja appliances can be found in the Tech Specs section of each product on our website and is published on our packaging, although please note that when the product is in use, the wattage and energy
usage will vary based several factors, e.g. which cooking mode is used, what food you are cooking, whether the appliance has been opened during cooking, and more.
