Equipment

  • Skillet
  • Baking sheet
  • Parchment paper
  • Knife and cutting board
  • Spoon or spatula
  • Oven

Ingredients
  

  • 2 large yellow onions, thinly sliced
  • 1 tbsp butter or olive oil
  • 1 sheet puff pastry (thawed if frozen)
  • 4 oz soft goat cheese (chèvre)
  • Salt to taste
  • Optional: fresh thyme, balsamic glaze, egg wash

Instructions
 

  • Caramelize onions: Cook sliced onions in butter/oil over low heat for 40–45 minutes, stirring occasionally until deep golden and jammy. Add a pinch of salt and optional splash of balsamic vinegar.
  • Prepare pastry: Roll out puff pastry on parchment-lined baking sheet. Score a ½-inch border around the edges with a knife (don’t cut through). Dock the center with a fork.
  • Layer toppings: Spread caramelized onions evenly over the pastry. Crumble goat cheese on top.
  • Bake: Bake at 400°F (200°C) for 20–25 minutes until pastry is golden and bubbling.
  • Cool slightly: Let rest for 5–10 minutes before slicing.

Notes

  • Use room temperature goat cheese for easier crumbling.
  • Don’t overcrowd the tart—less is more for crisp pastry.
  • Let puff pastry rest before baking to improve rise.
  • Brush edges with egg wash for a golden finish.
  • Add fresh herbs after baking for brightness.
  • Freeze unbaked tart for future use—bake directly from frozen with extra time.
  • Reheat leftovers in the oven to preserve flakiness.
