Ingredients
  

1 sheet of puff pastry, thawed

3 large onions, thinly sliced

2 tablespoons olive oil

1 teaspoon balsamic vinegar

1 teaspoon sugar

1 teaspoon thyme leaves (fresh or dried)

1 cup Gruyère cheese, shredded

1/2 cup ricotta cheese

Salt and pepper, to taste

1 egg, beaten (for egg wash)

Instructions
 

Begin by preheating your oven to 400°F (200°C). This will ensure that it's hot enough to create a perfectly baked tart.

    In a large skillet, pour in the olive oil and place it over medium heat. Once the oil is warm, add the thinly sliced onions. Stir occasionally to prevent sticking and to ensure even cooking.

      Allow the onions to cook for approximately 15 minutes, stirring occasionally, until they start to soften and become translucent. Then, add the sugar, balsamic vinegar, thyme, salt, and pepper to the pan. Continue cooking the onions for an additional 20-25 minutes, stirring often, until they are richly caramelized and golden brown, developing a deep flavor.

        While the onions are caramelizing, lightly flour your countertop and roll out the puff pastry to fit your tart pan. Carefully transfer the rolled pastry to the tart pan and gently press it into the edges. Use a fork to prick the bottom of the pastry to prevent it from puffing up during baking.

          In a mixing bowl, combine the shredded Gruyère cheese and ricotta cheese. Stir until well blended. Spread this creamy cheese mixture evenly across the base of the prepared pastry.

            Once your onions have reached that beautiful caramelized stage, layer them generously on top of the cheese mixture in the tart.

              To achieve a golden, glossy crust, brush the edges of the pastry with the beaten egg using a pastry brush.

                Carefully place the tart into the preheated oven and bake for about 25-30 minutes, or until the pastry is puffed and a rich golden brown.

                  Once baked, remove the tart from the oven and allow it to cool for a few minutes. This will help the flavors settle and make slicing easier.

                    Prep Time: 20 minutes | Total Time: 55 minutes | Servings: 6

                      - Presentation Tips: For an elegant finish, serve the tart warm, garnished with a light sprinkle of fresh thyme leaves and a drizzle of balsamic reduction over the top for added flavor and sophistication.
