I have a fresh farm raised Turkey that calls for cooking at 325 degrees but I also want to bake a stuffed butternut squash in the same oven where the recipe calls for ithe stuffed squash to bake for 2 hours at 375 degrees. I am assuming that the stuffed squash could cook longer at the lower temperature, but since I have never made this dish before and it IS Thanksgiving with lots of people , I’d like to have an idea of how much longer? Thanks!
The way to approach this is to ask how much hotter 375 degrees is than 325 degrees from the starting temperature of the food, then use that factor to multiply the time.
Doing the calculations, if your food starts out at room temperature (assuming 65 degrees) then (375 - 65)/(325 - 65) = 1.1923, or 1.2 rounded up a tiny bit. So 120 minutes * 1.2 = 144, in other words 2 hours and 24 minutes. It's a rough calculation, but I've used it pretty successfully.
