Step 1

Heat oven to 200°F (93°C). Line a rimmed baking sheet with a cooling rack; set aside.

Step 2

Combine sweet potato, onion, garlic, cilantro and parsley in a large bowl. Add panko, cornstarch, flour, salt, pepper and ginger. Stir to combine. Stir in eggs.

Step 3

Heat 1/2 centimeter of oil over medium heat in a large non-stick skillet. Working in batches of four, spoon 1/4 cup (60 milliliters) of the mixture into the hot oil and fry until golden brown on each side, four to six minutes, flipping halfway.

Step 4

Transfer to prepared sheet, sprinkle with salt and place in oven to keep warm while frying remaining batches.
