Convection ovens have an additional heating element and include a fan that blows the heat around more efficiently. Convection ovens cook faster than traditional ovens, but there are pros and cons of the convection oven.
Convection ovens can cook some food in half the time it takes in a traditional oven.
Convection ovens take some time to learn proper use. You will need to experiment with familiar recipes by shortening cooking time or decreasing temperature. While you are learning, you can expect some recipes to be over or undercooked.
Once you learn the quirks of your model, your convection oven will cook food at a higher quality than traditional ovens. Meats tend to be more tender and juicier, pie crusts more evenly baked and vegetables caramelized perfectly.
Convection ovens start around $100, but these aren't usually true convection ovens, because they lack the third heating element. To get a high-quality, true convection oven, you will spend $1,000 to $2,500, which is significantly higher than many traditional ranges.
Convection ovens heat more evenly than traditional ovens, leading to uniform baking, especially with cookies and pizza crust.
