Preheat oven to 400 degrees Fahrenheit (200 degrees Celsius).

Place eggs, oil, and salt into a 9×13-inch (23×33-centimeter) glass or foil pan set over a baking sheet and beat with a fork to combine.

Blend onion in the food processor using the S-blade until finely

shredded, then remove and transfer to the pan. Shred potatoes

using the fine shredder blade and add them to the pan. Mix well

to combine. (I like to mix it with gloved hands so no egg pools on

the bottom.)

Place the pan in the oven and bake at 400 degrees Fahrenheit (200 degrees Celsius) for half an hour, then lower the oven temperature to 375 degrees Fahrenheit (190 degrees Celsius) and continue baking for another two hours.
