Preheat Oven: Preheat your oven to 375°F (190°C). Greasing the baking dish with butter prevents the potatoes from sticking and adds a rich, buttery flavor.

Layer Potatoes: Arrange the thinly sliced potatoes evenly in the prepared baking dish. Ensuring the slices are uniform helps them cook evenly.

Add Herbs: Sprinkle chopped parsley and spring onion evenly over the potatoes. These fresh herbs add a pop of color and a burst of flavor that complements the potatoes and eggs.

Prepare Egg Mixture: In a bowl, whisk the eggs and season with salt, black pepper, and paprika. Whisking ensures the eggs are well mixed and the seasonings are evenly distributed.

Pour Over Potatoes: Pour the egg mixture evenly over the layered potatoes. The eggs will seep through the layers, binding the ingredients together as they cook.

Add Cheese: Sprinkle the shredded mozzarella cheese on top. As the dish bakes, the cheese will melt and form a deliciously golden crust.

Bake: Bake in the preheated oven for 25-30 minutes, or until the eggs are set and the cheese is melted and golden brown. The baking time ensures the potatoes are tender and the eggs are fully cooked.

Serve: Remove from the oven and let cool slightly before serving. This brief cooling period helps the dish set, making it easier to slice and serve.
