What Is A Steam Oven?

A steam oven is a kitchen appliance that uses the power of steam to cook food. Unlike traditional ovens that rely on dry heat (air), a steam oven uses moist heat (steam) to cook food, which can result in more flavorful and nutritious meals.

One of their main benefits is that it can help to retain the nutrients and vitamins in the food, as the moist heat can prevent the loss of water-soluble nutrients.

Additionally, steam cooking can help to preserve the natural flavours and textures of food, which can lead to more delicious meals. 😋

How Does A Steam Oven Work?

At its core, a steam oven’s primary tool is water. Here’s a simple breakdown of how it works:

  1. Water Reservoir: Steam ovens come equipped with a water reservoir or tank. Some high-end models might even be directly plumbed into a water source.

  2. Heating Element: Once the oven is activated, the heating element begins to heat the water.

  3. Steam Production: As the water heats up, it turns into steam, which then fills the oven cavity.

  4. Circulation: Fans or natural convection circulate this steam around the food, ensuring even cooking.

It’s pretty simple really! 😃

However, steam isn’t just hot air. It brings several benefits to the cooking process.

Pros Of Steam Ovens

  • Retains nutrients. Steam cooking can help to retain the natural vitamins and nutrients in food, as it cooks food without the need for excess oil or fat.

  • Enhances flavours. Steam cooking can help to enhance the natural flavours of food, resulting in more delicious and flavorful meals.

  • Versatile. Steam ovens can be used to cook a wide variety of foods, from vegetables and fish to meats and grains.

  • Healthier cooking option. Steam cooking is a healthier cooking option as it uses moist heat to cook food, without the need for added fats or oils.

  • Preserve texture. Steam cooking can help to preserve the natural textures of food, preventing overcooking and resulting in more tender and juicy meats and vegetables.

  • Energy efficient. Steam ovens can be more energy efficient than traditional ovens, as they can cook food more quickly and at lower temperatures, saving both time and energy.

  • Easy to clean. Steam ovens are typically easy to clean, as the moist heat can help to loosen and remove food debris and grease from the oven walls and racks.

  • Reheating leftovers. Using the steam or steam-combi setting is a fantastic way to reheat food. Bringing food back to life without drying it out.

Cons Of Steam Ovens

  • Higher cost. Typically, steam ovens will be more expensive than traditional ovens.

  • Learning curve. They may require a bit of a learning curve, as cooking times and temperatures may need to be adjusted to accommodate the different cooking methods.

  • Water and maintenance. Steam ovens require a water source, which can add to the maintenance and upkeep of the appliance. The presence of water and steam may also require more frequent cleaning and maintenance.

  • Limited browning. Steam cooking typically does not allow for the same browning or crisping that can be achieved with hot-air cooking methods, which may be a drawback for some dishes.

  • Size. Pure steam or compact steam ovens are usually smaller than your average-size built-in oven. So you may not be able to fit large amounts or multiple trays in to cook at once.

The Different Types of Steam Ovens

Here’s where things can get a little bit ‘technical’ and somewhat confusing as there are different types of steam ovens.

I’ve broken them down into the four main types below:

Pure Steam Oven

A pure steam oven uses only pure steam to cook food. Unlike other types of steam ovens, pure steam ovens do not use any external heating elements or microwaves to cook food.

Instead, they rely solely on high-pressure steam to cook food quickly and efficiently. They are typically a more compact size than regular ovens.

Full Steam Oven

A full steam oven is an appliance that can exclusively use steam to cook food, use steam alongside regular oven cooking or just be used as a standard oven.

The full-steam setting is ideal for cooking vegetables, fish, and other delicate foods that benefit from gentle, moist heat. While the ability to use other regular multifunction oven cooking makes them very versatile appliances.

Steam-Assisted Oven

A steam assist oven (sometimes called an oven with steam function or a combination steam oven) is an oven that uses a small amount of steam to help cook food more evenly and prevent it from drying out.

However, they are not able to use full (pure) steam to cook food.

These ovens typically have a water reservoir that releases steam during the cooking process but also use traditional dry heat cooking methods to create a crisp exterior on foods. Steam-assisted ovens are ideal for cooking roast meat, poultry, and baked goods that require a crispy exterior.

Combi Microwave Oven With Steam Function

A combi steam oven combines the features of both a full steam oven and a convection oven. These ovens offer the ability to use steam cooking, dry heat cooking, or a combination of the two, depending on the cooking needs of the user.

In addition, some combi steam ovens also offer the ability to use microwave technology, which can help to speed up cooking times. Combi steam ovens are versatile and can be used for a wide variety of cooking tasks. However, they are typically a compact size and smaller than a steam-assisted oven.

Key Features to Look for When Buying a Steam Oven

Purchasing a steam oven? These are the important features I would focus on:

  • Capacity and Size: Match the oven’s size to your kitchen space and cooking needs. Consider if it’s large enough for big family meals or compact for smaller kitchens.

  • Pre-set Cooking Programs: Seek ovens that offer pre-set programs. This feature simplifies cooking by auto-adjusting the temperature and time for various dishes.

  • Water Source: Decide between a Water Tank (manual refill) or a Plumbed-in Model (direct water connection). While tanks are more portable, plumbed models eliminate the need for refills.

  • User-friendly Controls and Display: Opt for an intuitive interface. Clear displays and easy-to-navigate controls enhance your cooking experience.

Are Steam Ovens Worth it?

Whether or not a steam oven is worth it depends on your individual cooking needs and preferences. Essentially, it boils (or steams) down to this:

Your Cooking Style: Perfect for delicate foods like fish and veggies which benefit from moisture retention. Not as necessary if you mainly roast or bake with dry heat.

Your Budget: Typically pricier than traditional ovens. Evaluate if you’ll use its unique features enough to justify the cost.

Your Kitchen Space: Requires adequate space. If limited, weigh its benefits against the footprint it’ll occupy.

In essence, while steam ovens are great at preserving moisture and nutrients, conventional ovens offer a broader range of cooking styles.

However, if you frequently cook delicate foods and are looking for a versatile and convenient cooking appliance, a steam oven may be worth the investment.


Can a steam oven be used as a regular oven?

Yes and No. Whether a steam oven can be used as a regular oven will depend on the type/model you purchase.

Some steam ovens are equipped with a combination cooking mode. This allows the user to use both steam and/or dry heat to cook food.

However, pure, steam-only steam ovens are designed to cook food using only steam.

Are Steam Ovens energy-efficient?

Steam ovens can be energy efficient for certain types of cooking, but the specific energy savings will depend on the model and how it is used.

Steam ovens can sometimes be more energy efficient compared to traditional ovens. As steam ovens use moisture to cook food, they can help to retain moisture and reduce the cooking time for certain types of food. This can result in energy savings, as the oven does not need to be heated for as long as a traditional oven would.

Final thoughts…

So there you have it, everything you need to know about steam ovens!

From perfectly cooked vegetables to deliciously moist cakes, steam ovens offer a unique way to prepare a variety of foods.

While they may not be for everyone, steam ovens can be a great addition to any kitchen for those looking to experiment with new cooking techniques and flavours.

So why not give it a try? Your taste buds (and your stomach) will thank you!
