How do you preheat an oven?

1. Turn on your oven. The first step is to turn on your oven and set it to the desired temperature.

2. Wait for the oven to reach temperature. Most ovens will have a light that turns on when the oven is preheated. Once the light turns on, your oven is ready to use.

3. Place your food in the oven. Once the oven is preheated, you can place your food in the oven and start cooking.

Tips:

- To ensure that your food cooks evenly, make sure to preheat your oven for at least 10 minutes before cooking.

- If you are using a convection oven, you may need to preheat it for a shorter period of time, as convection ovens circulate hot air which can cook food faster.

- Always check the temperature of your oven before cooking, as some ovens may not be accurate and may run hotter or colder than the temperature setting indicates.
