Only use for large amounts: Only roast pieces of meat over 1 kilogram in the oven. The hob is more economical for smaller amounts.
Avoid pre-heating: Many recipes say that the oven should be pre-heated. However, this is only really necessary for sensitive pastries e.g. for sponge mixtures or puff pastries. You can do without pre-heating for most dishes.
Keep the oven door closed: Do not open the oven door more often than necessary to prevent the loss of heat.
Use several shelves: In fan-assisted ovens, you can roast and bake on up to four different shelves at the same time. You can even prepare different dishes. Complete meals with vegetables, side dishes and meat can also be prepared simultaneously to make optimal use of energy.
Switch off early: Use the oven’s residual heat by switching off 5 to 10 minutes before reaching cooking time.
Built-in microwave: If a microwave is integrated into the oven, you can save time and electricity by using both at the same time.
