2 tablespoons olive oil

2 tablespoons unsalted butter

1 teaspoon sugar

1 teaspoon salt

1 cup ricotta cheese

1 cup shredded mozzarella cheese

Instructions
 

Preheat the Oven: Preheat your oven to 400°F (200°C).

    Caramelize the Onions: In a large skillet, heat the olive oil and butter over medium heat. Add the thinly sliced onions, salt, and sugar.

Remove from heat and set aside to cool slightly.

          Layer the Onions: Spoon the caramelized onions over the ricotta layer, spreading them out evenly. Finally, sprinkle the shredded mozzarella cheese over the top.

            Bake: Bake the tart in the preheated oven for 20-25 minutes, or until the pastry is golden brown and the cheese is bubbling.

              Finish and Serve: Remove the tart from the oven, and let it cool for a couple of minutes. Drizzle lightly with balsamic glaze, if desired, for added flavor. Slice into wedges and serve warm or at room temperature.
