Do you leave the oven on or off once is preheated?

The best practice is to turn off the oven once it has preheated.

- Reasons to turn the oven off includes:

- Safety: Leaving the oven on unnecessarily increases the risk of accidents, such as burns or fires, especially if you have children or pets in the house.

- Energy Efficiency: Keeping the oven on consumes energy even when it's not in use. Turning it off saves energy and reduces electricity bills.

- Consistent Cooking: Some recipes may require a specific oven temperature. By turning off the heat, you can better maintain the desired temperature and ensure even cooking.

- Reduced wear and tear: Constantly leaving the oven on can shorten the lifespan of the appliance's heating elements and other components. Turning it off helps extend the oven's life span.

- Avoiding Overheating: Leaving the oven on for too long can lead to overheating, which can damage the oven and potentially cause a fire.

Overall, it's recommended to turn off the oven once it has preheated unless the recipe specifically states otherwise or if you plan on using it immediately.
