Can you bake without an oven

Bake without preheating - cook with residual heat - energy saving tip # 4

In times of rising electricity prices, it is good to know how to use energy sensibly in the household and thus save energy costs. Opinions are divided on the subject of “Preheating the oven: yes or no?”.
While old ovens take up to 20 minutes to reach full temperature, modern ovens often only need a few minutes. With a few exceptions, preheating the oven is almost always a waste of energy. In our energy saving tip no. 4 we discuss why and how you can optimally use residual heat in the oven and on the stove.

Why preheating is mostly recommended

Hardly any recipe or preparation instructions on ready-made meals can do without the note "Preheat the oven". Why this is so is easy to explain. To a specify the specific baking time in all instructions and recipes from the full operating temperature went out. If you put a dish in the oven without preheating, the baking time is usually only extended by a few minutes, as your food will be warm, defrosted or cooked while it is being heated. Not only when the recommended temperature has been reached. How many minutes longer your oven dish will take depends on your oven. It is best to have one monitor the actual baking time examining look through the glass window. In order not to waste valuable energy in the process, you should Oven closed hold. When opening, up to 20 percent of the energy can be lost!

These dishes turn out perfectly even without preheating!

When baking without preheating, you can save up to 20 percent energy and thus a lot of money over the year. Use in baking and frying dark metal shapesas these reduce the baking time. Roasting and baking tins made of ceramic, on the other hand, extend the baking time! You can safely put the following dishes in the cold oven:

  • Aufbackbrötchen
  • Ready meals
  • Frozen meals
  • Homemade bread
  • Vegetable and pasta bakes
  • Yeast cake
  • Shortcrust cake
  • Tarts
  • cookie
  • Roasts and other meat dishes

We recommend preheating the oven for these dishes

Some dishes - especially special types of dough - need full temperature in order to rise and not collapse. Preheating is also worthwhile for dishes that are to be prepared at high temperatures in a short period of time. Before you preheat your oven, you should also empty it completely - because an empty baking sheet in the oven also consumes energy during preheating. Preheating is recommended for the following dishes:

  • Biscuit Dough
  • Choux
  • puff pastry
  • Soufflés
  • Fish dishes

If you use the circulating air instead of Top and bottom heat use, you can prepare your cakes, casseroles or roasts at a temperature 20 to 30 degrees lower and thus save around 30 to 40 percent energy.

This is how you use the residual heat when cooking and baking

Many experienced cooks know that it is worth using the oven or that Hob five to ten minutes switch off before the end of the cooking or baking timeto save energy and money. In our energy-saving tip 4, we show you even more ways in which you can optimally use the residual heat when cooking and baking.

What you can prepare with residual heat from the oven

  • Leftover bread for bread dumplings or croutons
    If you want to use old rolls or leftover bread, you can cut them into small cubes and dry them on a baking sheet in the oven while it is still warm.
  • Dry vegetables
    What works with old baked goods also works with chopped vegetables. After drying in the oven, the vegetables are stored in sealable jars and used to flavor soups and sauces.
  • Heat the water and milk in the oven
    Whether warm water for washing up or for a cup of tea or cocoa after dinner: Thanks to the residual heat in the oven, you don't have to turn on your hob or kettle.
  • bake cookies
    Even simple cookies can be baked in the oven with residual heat.
    For this, however, you should have prepared the cookies on the baking sheet and put them in the oven right away so that they become crispy.

Cook with residual heat on the hob

Here, too, there are a few tricks to save electricity and money. As in the oven, the residual heat from hotplates and ceramic hobs can be used to heat liquids such as water and milk or to warm up a dish.

Basically, when cooking - whether with residual heat or during a normal cooking process - you should make sure that the Cooking pots match the size of your hotplates or hobsso as not to waste energy unnecessarily. You can also save a lot of electricity when you cook with a tightly fitting lid. Since cooking with lids shortens the cooking and cooking times, you can save two to three times as much energy with this simple measure.


Depending on the energy efficiency of your oven and stove, you can take simple measures such as

  • Switch off the oven and stove five to ten minutes before the end of the cooking or baking time
  • Set circulating air instead of top and bottom heat
  • Keep the oven door closed
  • Use residual heat on the hob and in the oven
  • Cook with the lid on

Significantly lower the electricity demand in your kitchen and look forward to significantly lower electricity costs at the end of the year.

By the way, you can achieve the best energy balance in the kitchen if you only cook on the hob and do without the oven. But since cakes and oven-baked dishes should not be missing in a good kitchen, just take our energy-saving tip no. 4 to heart for resource-saving cooking and baking. We wish you good luck and bon appetite!
