Description

This Pumpkin, Ricotta & Caramelized Onion Tart with Bacon and Sage layers creamy pumpkin-ricotta filling with sweet caramelized onions, smoky bacon, and crispy sage on flaky puff pastry. It’s a showstopping fall dish perfect for brunches, dinners, or holiday gatherings.


Ingredients

Scale
  • 6 slices bacon, chopped
  • 4 sweet onions, thinly sliced
  • Kosher salt and freshly ground black pepper, to taste
  • ½ cup apple cider
  • 2 sheets frozen puff pastry, thawed
  • 1½ cups ricotta cheese
  • 1⅓ cups pumpkin purée (not pie filling)
  • 2 cups freshly grated mozzarella cheese
  • 2 handfuls fresh sage leaves
  • 2 large eggs + 2 teaspoons water (for egg wash)
  • Grated Parmesan cheese, for topping

Instructions

  1. Preheat the oven: Set your oven to 400°F (200°C). Line two large baking sheets with parchment paper.
  2. Cook the bacon: In a large skillet over medium heat, cook the bacon until crispy. Remove with a slotted spoon and set aside, reserving about 1 tablespoon of the rendered fat.
  3. Caramelize the onions: In the same skillet, add the sliced onions and a pinch of salt. Cook slowly over medium-low heat, stirring occasionally, for about 20–25 minutes until golden brown and soft. Add the apple cider and cook for 3–4 minutes, scraping up any browned bits. Let cool slightly.
  4. Prepare the filling: In a medium bowl, mix together ricotta cheese, pumpkin purée, and 1 cup of mozzarella. Season generously with salt and pepper.
  5. Assemble the pastry: Roll out each sheet of puff pastry slightly and place on prepared baking sheets. Score a 1-inch border around the edges (don’t cut all the way through). Prick the center with a fork to prevent puffing.
  6. Layer the tart: Spread the pumpkin-ricotta mixture evenly inside the borders. Top with caramelized onions, bacon, and the remaining mozzarella.
  7. Add the egg wash: Brush the pastry edges with beaten egg mixed with 2 teaspoons of water for a golden finish.
  8. Bake: Transfer to the oven and bake for 20–25 minutes, until the pastry is golden and puffed.
  9. Crisp the sage: While baking, heat a small amount of oil or butter in a skillet over medium heat. Add sage leaves and fry for 10–15 seconds until crisp. Drain on paper towels.
  10. Finish and serve: Sprinkle the baked tart with Parmesan and crispy sage leaves. Slice and serve warm or at room temperature.

Notes

Active time: 30 minutes; Passive time: 35 minutes.

Use high-quality puff pastry for best results — brands like Dufour or Pepperidge Farm bake up beautifully.

The tart can be assembled up to a day in advance and baked just before serving.
