Learn how controlled moisture and heat work together to improve texture, protect nutrients, and refine the way food cooks.
The way food cooks is largely determined by how heat is transferred. In traditional ovens, dry air surrounds the food, which can lead to uneven cooking and moisture loss. Steam cooking works differently. By introducing moisture into the oven, heat is transferred more efficiently, helping ingredients cook evenly while retaining their natural structure and nutrients.
How steam transfers heat through food
Before understanding the benefits of steam cooking, it helps to look at how heat moves around food inside the oven. The way heat is transferred plays a key role in how evenly food cooks, how much moisture it retains, and how its texture develops.
Dry heat: Circulating hot air
In a conventional oven, heat is transferred through hot, dry air that circulates around the food. While this method is effective, dry air is less efficient at transferring heat, which can lead to slower, less even cooking.
As hot air moves across the surface, it also draws moisture out of the food. This is what creates browning and crispness, but it can also increase the risk of drying out, especially with longer cooking times.
Steam heat: Moisture in motion
Steam cooking introduces water vapour into the oven cavity, creating a humid environment where heat is transferred more efficiently. Because steam carries more energy than dry air, it surrounds the food and delivers heat more evenly across its surface.
At the same time, the presence of moisture reduces evaporation from the food itself. This helps ingredients retain their natural texture, while still allowing the desired finish to develop when combined with heat and airflow.
What happens to food during steam cooking
Steam cooking isn't just about adding moisture to food, it’s a dynamic process where heat and humidity interact with food at different stages to influence texture, structure, and moisture retention.
- Steam generation: As the oven heats, water is converted into steam, creating a humid environment around the food from the start. This helps reduce early moisture loss from the surface.
- Heat transfer: Steam carries heat more efficiently than dry air, allowing it to circulate evenly around the food. This supports more consistent cooking from edge to centre.
- Moisture retention: The presence of steam slows down evaporation during cooking, helping food retain its natural moisture. This results in more tender textures and less dryness.
- Surface development: Steam allows the surface of food to develop more gradually during cooking. This supports better rise in baking and balanced browning without excessive moisture loss.
How Electrolux steam functions work
Electrolux steam ovens are designed with dedicated functions that combine steam and heat in different ways, depending on what you’re cooking.
- SteamRoast uses steam throughout the cooking process alongside hot air, making it ideal for roasting meats and larger dishes while retaining moisture.
- SteamBake introduces a touch of steam during baking to help dough rise more effectively, creating richer colour, crispier crusts, and a soft, well-structured interior.
This tailored approach allows you to match the cooking method to the dish, giving you greater control over both texture and finish. To understand how these principles translate into everyday cooking, explore our guide to using SteamRoast and SteamBake.
The power of steam cooking
Steam cooking changes the way energy interacts with food; shifting from a dry, extractive process to one that is more balanced and controlled.
Heat is transferred more efficiently for even cooking
Steam carries more thermal energy than dry air, allowing heat to circulate more effectively around food. This helps it cook more evenly from edge to centre, reducing hot spots and preventing the exterior from overcooking before the inside is ready.
Moisture is retained to protect texture and structure
During cooking, steam slows the evaporation of moisture from within the food. This helps maintain its natural structure, resulting in more tender proteins, softer baked goods, and textures that don’t dry out or toughen.
Nutrients are better preserved during cooking
Since steam cooking reduces moisture loss and supports more even heat distribution, it helps limit the breakdown of delicate, water-soluble nutrients. This allows food to retain more of its nutritional value, along with its natural colour and flavour.
A more controlled environment leads to more consistent results
By combining heat with controlled humidity, steam creates a more stable cooking environment. This balance allows food to cook more evenly and predictably, making it easier to achieve consistent results across different dishes.
4 Misconceptions about steam cooking
Despite its benefits, steam cooking is often misunderstood. Many of these misconceptions come from associating steam with basic or limited cooking methods, rather than the controlled, modern approach used in today’s ovens.
1. Steam cooking makes food soggy
This is one of the most common assumptions, but in practice, steam is carefully controlled throughout the cooking process.
Rather than saturating food, steam works alongside heat and airflow to maintain moisture where it’s needed. This helps prevent food from drying out, while still allowing surfaces to develop the desired finish like a crisp crust or a well-browned exterior.
2. Steam is only suitable for simple or bland dishes
Steam cooking is often associated with plain vegetables or basic meals, but its role is much broader.
By helping ingredients retain their natural moisture and structure, steam actually enhances flavour and texture. It supports everything from roasted meats to baked goods, allowing dishes to develop depth while maintaining balance.
3. Steam replaces traditional cooking methods
Steam doesn’t replace dry heat, but it does work well with it.
Modern steam ovens like Electrolux steam ovens combine heat, steam, and airflow to create a more controlled cooking environment. This means you can still achieve familiar results like browning and crispness, while benefiting from improved moisture retention and consistency.
4. Steam cooking is complicated to use
While the science behind steam cooking is advanced, using it is straightforward.
With dedicated functions designed for different cooking styles, it becomes easier to achieve the result you’re aiming for without needing to adjust techniques or overcomplicate the process.

Frequently asked questions when choosing integrated kitchen appliances
-
Why does steam cook food more evenly than dry heat?
Steam transfers heat more efficiently than dry air, allowing it to surround food and deliver energy more consistently. This helps reduce temperature differences between the outside and centre, resulting in more even cooking.
-
How does steam help retain moisture in food?
In a steam cooking environment, the surrounding humidity slows down evaporation from the food itself. This helps ingredients retain their natural moisture, preventing them from drying out during cooking.
-
Does steam cooking affect the texture of food?
Yes. By reducing moisture loss, steam helps maintain the natural structure of ingredients. This can result in more tender proteins, softer baked goods, and textures that are closer to their intended outcome.
-
How does steam help preserve nutrients?
Many vitamins are sensitive to heat and moisture loss. Because steam cooking reduces evaporation and supports more even heat distribution, it can help limit nutrient breakdown and preserve more of the food’s natural nutritional value.
-
Can steam cooking still create browning and crispness?
Yes. When combined with heat and airflow, steam allows surfaces to develop gradually. This means food can retain moisture internally while still achieving a crisp or well-browned exterior.
