Bulgarian-Style Potato Gratin

Combine the cottage cheese and butter, then whip with a mixer.

Season the cheese mixture with salt and pepper.

Peel the potatoes and slice them into rounds.

Arrange a single layer of potato slices on the bottom of a baking dish.

Spread the cheese mixture evenly over the potatoes.

Continue layering, making sure the final top layer is potatoes.

Tightly cover the dish with foil and bake in a preheated oven at 200°C (400°F) for 45 minutes.

Whisk together the eggs, yogurt, salt, and pepper.

Remove the dish from the oven, pour the egg and yogurt mixture over the top, and sprinkle with grated hard cheese.
