Steam Cooker vs. Steam Oven: That's the difference

Steam cookers vs. steam ovens: If you want to cook food particularly gently, these are essentially the two types of appliance to choose from. We’ll pit them against each other – and highlight the pros and cons of both options for you.

Key Points

    The choice between a steam cooker and a steam oven depends on individual cooking habits and kitchen equipment

    Steam cookers are designed specifically for steam cooking

    Steam ovens offer both cooking and baking functions

    Crispy dishes turn out perfectly only in a steam oven

How it works: Steam Cooker vs. Steam Oven

Steam cooking refers to the gentle preparation of foods such as vegetables, fish, and meat using water vapor at temperatures between 30 and 100 °C. The food is steamed without fat, and most of the vitamins and minerals are preserved.  

 

This method of preparation can be carried out using two different types of equipment. There are a few differences between steam cookers and steam ovens: 

 

Steam cooker

  • The classic steam cooker has multiple levels and a heating element at the bottom. It is filled with water and heated so that the rising steam circulates around the food and cooks it. As a built-in steam oven, it can be integrated into the kitchen, much like an oven. 

 

  • Depending on the model, two technical principles are used. In internal steam generation, the appliances heat the water directly in a tray at the bottom of the cooking chamber. With external steam generation, the process takes place outside the cooking chamber, and the steam is directed into the chamber.  

 

  • There are also steamers with a water tank or a direct water connection. 

 

Steam oven

  • When a steam cooker is combined with a conventional oven, the result is called a steam oven.  

 

  • With these combination appliances, you can steam food as needed and bake with or without added moisture: This method makes dishes especially crispy, tender, and juicy. Baking with a burst of steam is called "steam baking." 

 

  • Steam ovens are also available with a water tank or a permanent water connection—this detail is usually not a deciding factor when choosing between a steam cooker and a steam oven. 

 

For example, the BORA X BO is a steam oven with a permanent water connection. Like the BORA multi-drawer, we designed it with a focus on consistent convenience.

    Steam Cooker vs. Steam Oven: Advantages and disadvantages in detail

    When choosing between a dedicated steam cooker and a combination steam oven, individual cooking habits and space requirements play a decisive role. Our comparison highlights the key features of both systems to help you make your decision.

      What can I cook in a steam oven compared to a steam cooker?

      While a conventional steam cooker specializes in gently cooking vegetables, fish, and side dishes using steam, a steam oven significantly expands the range of cooking options to include the following:

       

      • Steam baking: The combination of hot air and moisture ensures professional results—bread comes out crispy, and roasts stay juicy. 

       

      • Traditional baking: all the features of a conventional oven for cakes, casseroles, and pizza. 

       

      • Special features: High-end models offer sous-vide cooking, reheating (gentle warming), defrosting, and sterilization. This also applies to steam-only cookers in this category. 

       

      With a steam oven, you can prepare the same dishes as in a steam cooker—and more. This combination appliance can completely replace a separate steamer. 

        Decision-making guide: Steam Cooker vs. Steam Oven

        Strictly speaking, the question isn't usually "steamer vs. steam oven." After all, an oven is a standard feature of any kitchen. So the real question is rather: Would a steam oven or a combination of two separate appliances be a better solution for you?

         

        Steam ovens allow you to bake with added moisture, a process known as "steam baking." However, this isn't necessarily a deciding factor—there are also standard ovens with this feature.

         

        This leaves two key factors to consider when deciding between a steam cooker and a steam oven:

        Available space

        Ultimately, it all comes down to what your top priority is. Once that’s decided, the question of whether to choose a steam cooker or a steam oven answers itself. If you choose the second option, the focus shifts to installing the steam oven correctly.

          Cooking characteristics

          With a combination of an oven and a steamer as standalone appliances, you can bake and steam different dishes at the same time. This is not possible with every combination unit.

            “A dedicated steam cooker is an excellent specialised appliance, but the modern steam oven is the Swiss Army knife of the kitchen. It doesn’t just replace two appliances; through the precise combination of moisture and heat, it takes cooking to a whole new level. A roast browns perfectly on the outside in the steam oven whilst remaining juicy on the inside – the result is a taste experience that is almost impossible to achieve any other way.”

            Frequently Asked Questions About Steam Cookers and Steam Ovens

            Standard ovens are not designed for steam cooking. If you don't want to buy a steam cooker or a steam oven, a steamer insert for pots is a good alternative. This is the simplest method of steam cooking.

            A steam oven offers three functions in one while taking up relatively little space: Steam cooking, conventional baking, and "moisture-assisted baking"—that is, baking with added moisture. This ensures that a wide variety of foods turn out perfectly—juicy, tender, and/or crispy, just the way you like them.

            Both types of appliances typically use the standard niche height of 45 or 60 cm. However, the steam oven saves space overall, since it replaces the traditional oven. If you have a separate steam oven, you will definitely need a second cabinet space for the additional oven. 

            Generally speaking, yes. In a steam-only cooker, the only things that usually build up are moisture and limescale. In a steam oven, the baking and roasting functions can cause burnt-on residue to build up, which is more difficult to remove. However, high-quality combination units such as the BORA X BO typically usually feature automatic cleaning programs using hot steam and special cleaning cartridges, which significantly reduce the effort required. 

            High-quality steam ovens typically cost about twice as much as standard steam cookers in the same quality class because they combine a steam function and an oven in a single appliance. The exact difference depends heavily on the brand, features, and installation type. However, when you consider the total cost of the kitchen, this difference is put into perspective: Since the steam oven completely replaces a traditional oven, there is no need to purchase a second major appliance. Compared to buying two separate devices, the bundle can often be up to a third cheaper.
