Sweet Potato Hash Browns

Combine sweet potato, shallot, garlic, 1 tablespoon oil, salt and pepper in a large bowl.

Heat 1 tablespoon oil in a large cast-iron skillet over medium-high heat. Form three 1/2-cup sweet potato patties in the pan, flattening them with a spatula. Cook the patties, turning once and lowering heat to medium if the pan gets too hot, until nicely browned on both sides, 6 to 8 minutes total. Transfer to a baking sheet and cover to keep warm (or keep in a 200 degrees F oven). Repeat with the remaining 1 tablespoon oil and the remaining sweet potato mixture.
