Preheat your oven to 350°F (175°C). Gather all ingredients and equipment.

Coarsely grate your sweet potatoes and soak them in cold water for about a minute to release excess starch.

Squeeze out as much moisture as possible from the grated sweet potatoes using a kitchen towel.

In a medium bowl, combine the drained grated sweet potatoes, chopped onions, eggs, flour, salt, and pepper. Mix until cohesive.

Heat a large skillet over medium heat and add cooking oil, allowing it to heat for about 2 minutes.

Scoop heaping tablespoons of the mixture into the skillet and flatten each scoop with a spatula.

Cook each potato patty for 3-4 minutes until golden brown and then flip to cook the other side.

Transfer the cooked hash browns to a baking sheet and place in the oven for an additional 10-12 minutes.
