Recipe Information
Ingredients
- 2 tablespoons Butter
- 1 tablespoon Olive oil
- 3 large Yellow onions
- 1 teaspoon Sugar
- 0.5 teaspoon Salt
- 2 teaspoons Fresh thyme leaves
- 1 sheet Store-bought puff pastry
- 1 large Egg
- 1 tablespoon Heavy cream
- 0.25 cup Crumbled goat cheese (optional)
Instructions
Preheat your oven to 400°F (200°C).
Slice the large yellow onions into thin rings.
In a large skillet, heat the butter and olive oil over medium heat until melted.
Add the sliced onions, sugar, and salt to the skillet, stirring to coat the onions evenly.
Cook the onions on medium-low heat, stirring occasionally, for about 25-30 minutes, until deeply golden and caramelized. Add the fresh thyme leaves in the last few minutes of cooking. Remove from heat and set aside.
On a lightly floured surface, roll out the puff pastry sheet to smooth out creases. Use a 2.5-inch round cutter to cut out circles of dough. Re-roll scraps if needed to get more circles.
Place the pastry circles onto a parchment-lined baking sheet.
Whisk the egg and heavy cream together to make an egg wash. Lightly brush the edges of each pastry circle with the egg wash to promote a golden crust.
Place about 1 tablespoon of the caramelized onion mixture in the center of each pastry circle. If desired, sprinkle a small amount of crumbled goat cheese on top.
Bake the tartlets in the preheated oven for 15-20 minutes, or until the pastry is puffed and golden brown.
Remove from the oven and let cool slightly before serving. Serve warm or at room temperature.
