How to make
Cut the potatoes into very thin slices with a sharp knife and grate the onion.
Dry the potatoes atop paper towels and fry them on a medium stove in heated olive oil, while also adding in the onions and garlic. Cook about 15-20 min, until the onion caramelizes.
Beat the eggs with salt and black pepper. Add the cooled potatoes and let the mixture sit for 15-20 min.
Smear 3″ (7 cm) tortilla bowls with olive oil and distribute the mixture. Bake about 12-15 min. in a 360°F (180 °C) oven.
You can serve the tortillas right in the bowls.
