We were goofing off the last time we ate this, which is how we came up with the name Eggopotamus. Actually it was me that called it this. It's a spin off tortilla de patata.
3 medium potatoes
1 medium onion, chopped
2 T butter
1/2 t each garlic powder & onion powder
Salt & pepper to taste
Peel your potatoes, then grate them onto a plate lined with paper towels. Spread them into an even layer & press more paper towels on top of them. This gets them as dry as possible for frying. While your potatoes are drying between paper towels, crack your eggs into a bowl & whisk with spices.
In a well-seasoned cast iron skillet, melt your butter. Add onions in a layer & spread your shredded potatoes atop the onions. Sprinkle with salt & pepper. Fry on medium heat until browned on the bottom. Lay a plate on top & carefully, but quickly, flip the potatoes & onions onto the plate. Slide back into the pan. Fry until browned. Add eggs, fry until they are done on the bottom, then flip again onto a plate. Slide into pan & cook until done through. You may also put them under a low broiler rather than doing the flip if you prefer.
Cut into wedges & serve.
