Detailed Directions and Instructions
Step 1: Caramelize the Onions
Heat the olive oil and butter in a large skillet over medium-low heat. Add the sliced onions with a pinch of kosher salt. Cook, stirring often, until the onions become caramelized, about 25 to 30 minutes. Lower the heat as needed to prevent burning.
Step 2: Prepare the Oven and Baking Sheet
Preheat the oven to 425°F (218°C). Line a baking sheet with parchment paper. Place the thawed puff pastry sheet on the parchment paper.
Step 3: Assemble the Tart
Spread the caramelized onions evenly over the puff pastry. Arrange the brie slices on top of the onions, followed by the apple slices. Sprinkle a pinch of salt and pepper over the apples if desired.
Step 4: Apply Egg Wash
Brush the exposed edges of the puff pastry with the egg wash.
Step 5: Bake the Tart
Bake in the preheated oven for 20 to 25 minutes, or until the pastry is golden and puffed.
Step 6: Finish and Serve
Remove from the oven and sprinkle the pomegranate arils over the tart. Drizzle with pomegranate molasses.
Step 7: Slice and Enjoy
Slice and serve warm.

Cook techniques
Caramelizing Onions
Caramelizing onions involves cooking them slowly over low to medium heat with fat (olive oil and butter) until they turn a golden brown color and develop a sweet, rich flavor. Stir them often to prevent burning and adjust the heat as necessary.
Using Puff Pastry
Puff pastry is a light and flaky pastry made by layering dough and butter. When using it, ensure it’s thawed if frozen and laid out flat on parchment paper for even baking. Brushing the edges with egg wash will give a beautiful golden finish.
Layering Ingredients
To create a balanced tart, layer the caramelized onions first for a flavorful base, then add creamy brie and thinly sliced apples for sweetness. Lightly seasoning with salt and pepper can enhance the flavors.
Baking Techniques
Bake in a preheated oven at the correct temperature to ensure even cooking. Keep an eye on the tart, and remove it once the pastry is puffed and golden, typically between 20-25 minutes.
Garnishing with Fresh Ingredients
Once the tart is baked, sprinkle fresh pomegranate arils for texture and a bright pop of color. Drizzling pomegranate molasses adds sweetness and a tangy flavor that complements the other ingredients.
