Ingredients

Scale

For the Tart Base

  • 1 sheet of puff pastry (store-bought or homemade)

For the Filling

  • 2 medium butternut squashes (about 2 lbs), peeled and diced
  • 2 large onions, thinly sliced
  • 2 tablespoons olive oil
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon fresh thyme (or 1/2 teaspoon dried thyme)
  • 1 cup goat cheese (or feta cheese for a tangier flavor)
  • 1/4 cup heavy cream (or a dairy-free alternative)
  • 1 egg (for egg wash)
  • Optional: A sprinkle of red pepper flakes for heat

Instructions

  1. Preheat the Oven: Preheat your oven to 400°F (200°C) to prepare for roasting the squash and baking the tart.
  2. Prepare the Butternut Squash: Toss the diced butternut squash with 1 tablespoon of olive oil, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper. Spread the squash evenly on a baking sheet and roast in the preheated oven for 25 to 30 minutes, or until tender and caramelized.
  3. Caramelize the Onions: While the squash roasts, heat the remaining 1 tablespoon of olive oil in a skillet over medium heat. Add the thinly sliced onions along with a pinch of salt and cook for about 20 minutes, stirring occasionally, until the onions are soft, sweet, and golden brown.
  4. Roll Out the Puff Pastry: On a lightly floured surface, roll out the puff pastry sheet to fit your tart pan or baking sheet. Transfer the pastry and prick the bottom with a fork to prevent bubbling during baking.
  5. Assemble the Tart: Spread the caramelized onions evenly over the puff pastry. Layer the roasted butternut squash pieces on top of the onions. Crumble the goat cheese evenly over the squash, then drizzle the heavy cream across the tart. Sprinkle with fresh or dried thyme, black pepper, and red pepper flakes if using for added heat.
  6. Brush with Egg Wash: Beat the egg and gently brush the edges of the puff pastry with the egg wash to achieve a golden crust.
  7. Bake the Tart: Place the assembled tart in the oven and bake for 25 to 30 minutes, until the puff pastry is golden and crisp, and the cheese is slightly melted.
  8. Cool and Serve: Remove the tart from the oven and allow it to cool for about 10 minutes before slicing. Serve warm or at room temperature.

Notes

  • You can substitute goat cheese with feta for a tangier flavor.
  • If you prefer a dairy-free option, use a plant-based cream alternative.
  • Adding red pepper flakes gives the tart a nice subtle heat but is optional.
  • Make sure to prick the puff pastry before baking to prevent it from puffing too much.
  • Caramelizing onions low and slow enhances their natural sweetness.
  • This tart pairs beautifully with a simple green salad or roasted vegetables.
