Caramelized Onion, Goat Cheese & Arugula Tart
Equipment
- 1 baking tray
Ingredients
- 2 large onions, thinly sliced
- 3 tbsp olive oil, divided
- 1 tbsp balsamic vinegar
- 1 sheet puff pastry
- 1/2 cup crumbled goat cheese
- 1 egg, beaten with 1 tbsp water optional
- 1 cup arugula
- salt and pepper to taste
Instructions
- Heat 1 tbsp of the olive oil in a skillet over low-medium heat. Add the onions, stir them to coat with the oil, and arrange them evenly in the pan. Cook for 10 minutes, stirring occasionally, until they soften, then season with a pinch of salt and pepper. Add the balsamic vinegar and stir. Continue to stir them or move them around every few minutes to ensure they are browning evenly. If the onions are burning or looking dry, reduce the heat to low. Cook them for another 30 minutes or until they are very soft and deeply caramelized. Let cool.
- Preheat the oven to 400°F. Line a baking sheet with parchment paper and lightly sprinkle it with flour. Roll out the sheet of puff pastry onto the lined baking tray into an 11×9 rectangle or any shape you want so that it is about 1/8 inch thick. If you are using pre-rolled puff pastry, feel free to leave it as is or roll it to be slightly thinner.
- Brush the pastry with the remaining olive oil and arrange the caramelized onions evenly over the top, leaving about a ½ inch border of pastry all around.
- Top with the crumbled goat cheese.
- Brush the sides of the pastry with the egg wash for a more golden brown and crispy pastry edge.
- Baked for 15-20 minutes until the edges of the pastry have puffed and the bottom is brown.
- Cool for 10 minutes, then scatter the arugula over top.
- For larger pieces, slice into 6 squares. For as maller appetizer bite, cut into 12 squares. Enjoy!
