How long does it take to bake food at 450 if supposed 350?

Baking food at a higher temperature does not reduce the baking time proportionally. In fact, it can lead to uneven cooking and potential burning of the food. When baking at a higher temperature, you need to reduce the baking time to prevent overcooking.

As a general rule, for every 25 degrees Fahrenheit (14 degrees Celsius) increase in oven temperature, you should reduce the baking time by about 10%. So, if a recipe calls for baking food at 350 degrees Fahrenheit (177 degrees Celsius) for 30 minutes, you would need to bake it at 450 degrees Fahrenheit (232 degrees Celsius) for approximately 22.5 minutes.

It's important to keep a close eye on the food while it's baking and adjust the time as needed based on its appearance and doneness.
