I buy the bags of the pre shredded potatos, maybe those work better I dunno.
Heat up a few table spoons of oil in 12" fry pan. Layer potatos about 3/8" inch thick, pack them down with your spatula.
Fry till they're golden brown, then drizzle some more oil on the uncooked side. Flip entire mass. Brown other side.
Usually then I mix them up a bit to fry the inside a little bit. Remove from heat, cover with cheddar.
Mmmmm!
