Step-by-Step Instructions
Here’s how to make Onion Cottage Cheese Tart:
Prepare the Caramelized Onions:
- Cook the Onions: Heat the olive oil in a large skillet over medium heat. Add the sliced onions, sprinkle with sugar, and season with salt and pepper. Cook for about 25 minutes, stirring occasionally, until the onions are golden brown and caramelized. Set aside to cool.
Prepare the Filling:

Assemble the Tart:
- Prepare the Puff Pastry: Preheat the oven to 375°F (190°C). Roll out the puff pastry on a lightly floured surface to fit your tart pan. Place the pastry into the pan, trimming any excess dough along the edges.
- Layer the Tart: Spread the cottage cheese mixture evenly over the puff pastry. Top with the caramelized onions, spreading them out evenly.
Bake the Tart:
- Bake: Place the tart in the oven and bake for 40-45 minutes, or until the pastry is golden and crisp, and the filling is set.
- Cool and Garnish: Allow the tart to cool slightly before removing from the pan. Garnish with fresh parsley if desired, and serve warm or at room temperature.
