Step 1

Preheat your oven to 400 degrees F. Put your choice of oil/fat on a rimmed baking sheet and put it in the oven. As the oven heats, it will heat up the pan and the oil. The oil should get hot, but not smoke. If it smokes, take it out and discard the oil and start over. You don't want burned oil. Ew.

Step 2

Shred or grate the sweet potatoes using a box grater or a grating disk on your food processor.

Step 3

While the pan and the oil is very hot, sprinkle the grated sweet potatoes evenly on the pan. Put it back in the oven on a lower oven rack. Roast for about 10 minutes and then flip the hash browns around. If they're getting too dark too fast, put the pan on a higher rack. Roast for about 5-8 more minutes until there are a lot of dark golden brown pieces and the potatoes are cooked through.

Step 4

Remove the pan from the oven and let them cool on the pan for about 10 minutes. (This will help them to crisp up a bit more than immediately piling them into a serving dish.) Sprinkle them with a few generous pinches of salt before transferring to a serving dish.
