What Is a Steam Assist Oven?

A steam assist oven is a built-in oven that combines traditional heat with added steam during cooking. Instead of relying on dry heat alone, it introduces moisture into the oven cavity to help food cook more evenly and stay tender inside while still browning on the outside.

If you enjoy baking bread, roasting meat, or cooking dishes that can easily dry out, a steam assist oven can make a noticeable difference to texture, flavour, and overall results.

Important: A steam assist oven is not the same as a full steam oven. It still works as a normal oven, but gives you the option to add steam when a recipe benefits from extra moisture.

How Does a Steam Assist Oven Work?

A steam assist oven uses conventional heating elements or fan cooking, then adds controlled bursts of steam at key stages of the cooking process. This helps maintain moisture inside the food while still allowing the outer layer to crisp and brown.

Main Benefits of a Steam Assist Oven

Better moisture retention for juicier meals
Improved baking results with better rise and crust
More even cooking from centre to edge
Better reheating without drying out leftovers

Tip: Steam assist is ideal for bread, roast meats, baked dishes, and reheating food while keeping it soft and flavourful.
