A tender pastry crust topped with sweet roasted onions and just a hint of herbs make this French onion tart a party favorite. A sprinkle of thyme and a handful of Parmesan pair deliciously with caramelized onions.


  1. Preheat Oven to 400F
  2. On a sheet pan drizzle some Della Terra Extra Virgin Olive Oil, Della Terra 25 year Balsamic, salt, black pepper, fresh thyme and grated Parmesan. Place sliced white pearl onions on top.
  3. Then cover with a rectangle cut of puff pastry dough and press down on all sides. It should look like a pop tart. Then brush with some egg wash (1 egg mixed with 1 tbsp of water) and place in the over until golden brown, roughly 20 mins.
  4. Flip them over and serve with whatever garnishes you want.
