A steam oven is an oven with steam function. Instead of using a fan oven function, these ovens use steam. You won't need any oil or butter anymore, which makes preparing dishes a lot healthier. On top of that, you retain the flavor and vitamins. What should you keep in mind when you want to buy a steam oven? Firstly, you have to consider the steaming method. This can be partial or full-fledged. When the oven uses partial steam, it only releases steam at the beginning of the baking process. You can use it to make lasagnas, pizzas, cakes, and bread without making them dry. With full-fledged steam, you can prepare entire dishes. Steam is used throughout the entire baking process.
