Boil the potatoes in a pot of water until tender. (For best results, cook them the day before.) Peel and let them cool completely, then cut them into ¼-inch (0.5 cm) thick slices.
1 ½ lb waxy potatoes
Peel and roughly chop the onion.
1 onion
Heat the oil and melt the butter in a large frying pan. (In Germany, clarified butter is traditionally used, but since it’s harder to find abroad, this method provides a buttery taste while maintaining a high smoke point.)
2 tablespoon neutral oil , 1 tablespoon butter
Place the potato slices in a single layer in the pan and fry until crispy, about 8–10 minutes. Avoid overcrowding the pan. If necessary, fry the potatoes in batches to ensure even crisping. Remove the potatoes from the pan and set them aside.
Add the onions and bacon to the pan and fry until the onions are translucent and the bacon is crispy.
3 ½ oz bacon cubes
In a separate bowl, crack the eggs and whisk them until smooth. Season with salt and pepper, then pour the mixture over the potatoes, onions, and bacon.
4 eggs, salt and pepper to taste
Cover the pan with a lid and cook the omelet over low to medium heat for approximately 5 minutes, or until the surface is fully set.
Serve immediately. This omelet pairs well with German pickles, beets, and a fresh salad.
