Ingredients

Caramelized Onions

  • 2 sweet onions, thinly sliced
  • 2 tablespoons olive oil
  • 2 tablespoons butter
  • Kosher salt, to taste

Tart Base and Toppings

  • 1 sheet puff pastry, thawed if frozen
  • 2 apples, thinly sliced
  • 8 ounces brie cheese, thinly sliced

Finishing Touches

  • 1 egg + 1 tablespoon water, beaten together for egg wash
  • ⅓ cup pomegranate arils
  • Pomegranate molasses, for drizzling


Instructions

  1. Caramelize the onions: Heat the olive oil and butter in a large skillet over medium-low heat. Add the thinly sliced onions with a generous pinch of kosher salt and stir frequently. Cook the onions slowly for about 25 to 30 minutes until they become caramel-colored and soft. Adjust heat as needed to avoid burning, ideally cooking them over low heat to develop rich flavor. The onions don’t have to be fully caramelized since they’ll continue cooking in the oven.
  2. Prepare the oven and pastry: Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper and place the sheet of thawed puff pastry on top. (Optional: create a decorative twisted border using an extra sheet of puff pastry cut into strips and twisted around the edges.)
  3. Assemble the tart: Spread the caramelized onions evenly over the puff pastry sheet. Layer the brie cheese slices over the onions, then arrange the thin apple slices on top. Optionally, sprinkle a pinch of salt and freshly ground black pepper over the apples. Brush the exposed edges of the puff pastry with the egg wash to ensure a beautiful golden crust.
  4. Bake the tart: Place the tart in the preheated oven and bake for 20 to 25 minutes, or until the puff pastry is golden brown and puffed up. Keep an eye on the tart to prevent burning and maintain a flaky crust.
  5. Add finishing touches and serve: Once baked, remove the tart from the oven. Immediately sprinkle the pomegranate arils over the tart and drizzle with pomegranate molasses for a burst of color and tangy sweetness. Slice and serve warm for the best flavor and texture. Leftovers can be reheated in a low oven for a few minutes but are best enjoyed fresh.

Notes

  • Use sweet onions like Vidalia or Walla Walla for the best caramelized flavor.
  • Thaw puff pastry completely before baking to ensure proper puffing.
  • Adjust the thickness of apple slices to your preference; thinner slices will cook more evenly.
  • Brie rind is edible and adds flavor; slice the cheese thinly along with the rind.
  • Keep a close watch while caramelizing onions to prevent burning, as caramelization is key to flavor.
  • Serve the tart warm for optimal taste, but it can be served at room temperature.
  • Pomegranate molasses adds a tangy sweetness; substitute with balsamic glaze if unavailable.
