Warm Church-Supper Upside Down Onion Tarts
Ingredients:
| Ingredient | Quantity |
| Large onions, thinly sliced | 2 |
| Olive oil | 2 tbsp |
| Butter | 1 tbsp |
| Brown sugar | 1 tbsp |
| Salt and pepper | To taste |
| Puff pastry | 1 sheet |
| Fresh thyme leaves (optional, for garnish) | For garnish |
Step-by-step Directions:
-
Prep the Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
-
Caramelize the Onions: Heat the olive oil and butter in a skillet over medium heat. Add the sliced onions and cook, stirring occasionally, until they are deep golden brown and caramelized (about 20/25 minutes).
-
Season: Sprinkle the brown sugar over the onions, season to taste with salt and pepper, and stir well. Cook for another 5 minutes to fully melt and integrate the sugar.
-
Assemble: Roll out the puff pastry on a lightly floured surface to fit your baking sheet. Spread the sweet caramelized onions evenly over the pastry.
-
Bake: Place the tart in the oven and bake for 20/25 minutes, or until the puff pastry is beautifully golden brown and crispy.
-
Flip and Serve: Remove from the oven and let it cool for just a few minutes. Carefully invert the tart onto a serving platter so the caramelized onions end up on top. Garnish with fresh thyme leaves if using, slice, and serve warm.
