How much can I expect to pay for a steam oven?

Steam ovens can be pricey and range in price from $2000 right up to over $7000. 

Do you need a steam oven?

For most cooks, a combination steam oven shouldn’t replace a conventional electric oven, because you can get better cooking results in a standard oven, or one with the added moisture settings, at a much lower cost.

But if you’re frequently steaming foods – particularly in larger volumes or multiple dishes such as rice, fish, veggies and/or puddings – a combi-steam oven may be a useful choice. A standalone steam oven to complement your existing electric multifunction oven is also worth considering.

The downside of any steam oven is the high level of maintenance needed to keep the water/steam system free of bacteria and mould. For less frequent steaming, the stovetop steamer or microwave will get the job done without leaving a hole in your hip pocket – or eating up too much of your free time. 

What size do I need?

Options are compact (about 45cm high by 60cm wide), or full size (about 60 x 60cm). Selection will depend on your available space, and how much steam and combi-steam cooking you do. Multi-shelf cooking in some models isn't recommended – reducing versatility. Check such recommendations before buying.

Which is your type?

There are three types of steam oven:

  • The standalone steam oven – which only steams
  • The 'true' combination steam oven has typical multifunctional baking, combination steam/convection modes, and steam only settings
  • A typical multifunction electric oven with an added moisture function. These inject bursts of steam into the oven during normal baking at appropriate cooking phases to help keep in moisture.

Steam only

Standalone steam ovens can steam large quantities of food over multiple shelves without fusing flavours. For example, you can steam fish, veggies, rice and pudding at the same time, and pretty quickly too. But you can’t brown food, which limits the versatility of these ovens.

Combination steam and convection ovens

These are the latest designs to infiltrate the showroom. As their name suggests they combine the benefits of steam cooking with all the necessities of a multifunction convection oven. A ‘true’ combination steam oven has typical multifunctional baking, combination steam/convection and steam-only settings. These tend to have water tanks (very few can be plumbed in) and some have condensation collection reservoirs.

A convection oven with a burst of steam, anyone?

Often, the cheaper option is a typical multifunction electric oven with an added moisture function. Some have a water tank and a drain and tube for emptying condensation water, while others draw water through a siphoning tube that you place in a glass of water. These don’t have steam-only settings, but simply inject bursts of steam into the oven during normal baking at appropriate cooking phases to help retain moisture. 

What to check in store

  • Water tank A larger water tank means less interruption while steam cooking. One that you can access without opening the oven door prevents heat and steam loss – and minimises the risk of scalds from escaping steam. Make sure it’s easy to fill and replace. The steaming system will need to be flushed through and descaled periodically, depending on how often you use it and water hardness.
  • Condensation Some have condensation tanks that need to be removed, emptied and replaced, others you drain by inserting a tube into the drain hole while water flows into a container you hold below it, and another type need the oven cavity sponged out after each use from an indented collection cavity in the base. On the other hand, some have no condensation tank or collection cavity – you just wipe dry the interior after each use. But we've found this may not be an ideal design, as moisture still seems to remain within the system, which isn't ideal for baking some dishes, including meringues. There are also plumbed-in options, but these require a fair bit of maintenance including descaling and regularly flushing the lines to prevent mould growing, and they’re more expensive to buy and install.
  • Comprehensive instructions and cooking guidelines There's lots to learn about combination-steam cooking, and good guidelines can help a great deal. It can only take 30 seconds to ruin a steamed dish, so accurate guidelines mean significantly less trial and error and more fun in the kitchen.
  • Controls Clear and intuitive controls and labelling are even more important with combi-ovens due to all the extra options available. It's worth trying them out in a store, where possible, to get a better idea of whether they're easy to use and understand
  • Cooking demonstrations on using a steam oven can help you get the most out of your new kitchen appliance.
