This is a frozen pie and yes... Put into a 375 oven while
still frozen and cook for 65-75 minutes.
My homemade pies cook for less time, like you are thinking.
This frozen pie was ok but had a bit of an off-taste,
like the oil used had gone rancid. Won't buy those again.
Might make a sweet potato pie next time soon.
I use the old Betty Crocker recipe then add
50% more spice. I like a spicy pie.
