Preheat oven to 180°C (350°F). Grease a small baking dish with butter or oil.

In a medium bowl, whisk the eggs with sour cream until smooth. Season with salt and black pepper.

Assemble the casserole:
Stir in the sautéed onion and half of the shredded cheese. Pour the mixture into the prepared baking dish.

Top with cheese:
Sprinkle the remaining cheese evenly on top.

Bake:
Place in the oven and bake for 25–30 minutes, or until the casserole is puffed, golden, and set in the center.
