When my sister was visiting, we also made this Sweet Potato Pie with Hazelnut Streusel. I haven't ever made sweet potato pie before, but I figured this was a good recipe to start out with. My sister isn't a fan of pie crust and we were looking to save time, so we made it without the crust.
It was easy and delicious. The streusel gave a nice crunch to the whole thing and we didn't miss the crust at all.
