Ingredients

  • 2 Tbsp olive oil
  • 1 large onion thinly sliced
  • 1 shallot thinly sliced
  • 4 large olives thinly sliced
  • 1/3 cup feta cheese crumbled
  • 4 -5 slices peppered salami
  • 1 Tbsp Pimento sauce or sliced pimentos
  • 4-5 sprigs Italian parsley
  • Flaky sea salt
  • Piment d’Espelette or black pepper
  • 1 sheet homemade puff pastry or store bought

Instructions

  • Preheat oven to 425°F and line a baking sheet with parchment paper. Drizzle the center of the parchment paper with olive oil. The size should match the dimensions of your piece of puff pastry.
  • Place the onions, shallot, olives, feta, salami, pimento sauce, and parsley decoratively over the olive oil. Sprinkle with salt, keep in mind that many of the ingredients are already salty, so do this with a light hand. Drizzle the remaining olive oil over the ingredients.

  • Drape the puff pastry over the ingredients on the parchment. Bake for about 20 minutes or until the puff pastry is caramel brown in color and evenly puffed, the center will puff last.

  • Carefully flip the tart over onto a serving tray or cutting board. If the onions and other ingredients are not fully cooked, slide the tart back onto the baking sheet, onion side up this time and return to the oven for another 5+ minutes or until the onions are golden brown on the edges.

For Mini Onion Tarts

  • Preheat oven to 400℉.
  • Divide the toppings (for the mini version I used 4 Tbsp. olive oil, thyme, olives, and tomatoes - save the cheese for later) in the bottom of 12 muffin cups.

  • Cover each with a slice of the onion.

  • Using a round biscuit or cookie cutter, cut out circles of the puff pastry (the circles should be slightly bigger than the top of the muffin cup since they will shrink in the oven) and place over the onion. Gently push the pastry over the onions, so they are a snug fit.
