These Feta and Caramelized Onion Tarts are a savory delight featuring a flaky homemade crust filled with sweet, deeply caramelized red onions and a creamy, tangy mixture of feta and cream cheese. The addition of balsamic vinegar, honey, and brown sugar enhances the onion’s natural sweetness, while fresh parsley adds a bright finish. Perfect as an appetizer or light meal, these tarts combine rich flavors with a crisp texture for a satisfying bite.

  • Total Time: 1 hour 15 minutes
  • Yield: 8-10 small tarts

Ingredients

For the crust:

  • 1¾ cups all-purpose flour
  • ½ cup butter, cold and cubed
  • 1 teaspoon salt
  • 1 teaspoon sugar
  • 3-6 tablespoons ice water

For the filling:

  • 1 tablespoon olive oil
  • 6 medium red onions, sliced
  • 1 tablespoon balsamic vinegar
  • 3 tablespoons light brown sugar
  • 1 tablespoon honey
  • Salt and pepper, to taste
  • 6 ounces feta cheese, crumbled
  • 2 ounces cream cheese, softened
  • 1 egg
  • 2 tablespoons fresh parsley, chopped

Instructions

  1. Prepare the crust: In a large bowl, combine the all-purpose flour, salt, and sugar. Cut in the cold, cubed butter using a pastry cutter or fingers until the mixture resembles coarse crumbs. Gradually add the ice water, one tablespoon at a time, mixing until the dough just comes together. Form the dough into a disk, wrap in plastic wrap, and refrigerate for at least 30 minutes to chill.
  2. Caramelize the onions: Heat the olive oil in a large skillet over medium-low heat. Add the sliced red onions and cook slowly, stirring frequently, until they become soft and golden brown, about 25-30 minutes. Add the balsamic vinegar, light brown sugar, and honey, stirring well to coat. Continue to cook for another 5 minutes until the mixture is thick and sticky. Season with salt and pepper to taste, then remove from heat and let cool completely.
  3. Make the filling: In a mixing bowl, beat together the feta cheese, cream cheese, and egg until smooth and well combined. Stir in the chopped fresh parsley.
  4. Assemble the tarts: Preheat the oven to 375°F (190°C). Remove the chilled dough from the refrigerator and roll out on a lightly floured surface to about 1/8 inch thickness. Cut into small rounds or squares to fit your tart pans or a baking sheet. Place the dough pieces on parchment-lined baking sheets or tart pans. Spread a layer of the caramelized onion mixture evenly onto each piece of dough, then spoon the cheese mixture over the top.
  5. Bake: Bake the tarts in the preheated oven for 20-25 minutes, or until the crust is golden and the filling is set and slightly browned on top.
  6. Serve: Remove from the oven and allow to cool slightly. Garnish with extra fresh parsley if desired, and serve warm or at room temperature.

Notes

  • For a crispier crust, chill the dough thoroughly before rolling out and baking.
  • If you prefer a milder onion flavor, use yellow onions instead of red.
  • The tarts can be made in advance and reheated gently in the oven before serving.
  • These tarts pair well with a light green salad and a crisp white wine.
