Why does nearly every frozen food require the oven to be preheated at 400 Fahrenheit? What is it about 400 degrees that’s such a sweet spot?
The hotter the oven, the faster it transfers heat into the food. Water requires a large amount of energy to melt, and a huge amount of energy to change its temperature regardless of what state it's in. A cool oven won't melt the food fast enough to avoid drying out or overcooking the outside.
The Short Answer
The hotter the oven, the faster it transfers heat into the food. Water requires a large amount of energy to melt, and a huge amount of energy to change its temperature regardless of what state it's in. A cool oven won't melt the food fast enough to avoid drying out or overcooking the outside. A hotter oven will dump more heat into the outer layer of food, melting it faster, but the inside will probably still be frozen because the heat is still going into melting the interior, which stays its melting point until it's completely melted. This results in an overcooked exterior with an icy interior, whereupon the diner will likely curse the manufacturer for providing poor food and/or poor cooking directions. The suggested cooking temperature will likely result in adequate cooking in a wide variety of ovens, some of which might be improperly set up (rack position vs. heating elements), out of calibration, or otherwise less than ideal.
