Instructions
- 1
Preheat your oven to 400°F and line a large baking sheet with parchment paper.
- 2
Heat 2 tablespoons of extra virgin olive oil in a large skillet over medium heat until shimmering, about 1 minute.
- 3
Add the thinly sliced onions to the hot oil and toss well to coat evenly, then lower heat to medium-low and cook for 18-20 minutes, stirring occasionally, until the onions develop a deep caramelized golden-brown color with slightly crispy edges.
- 4
Stir in the minced garlic and cook for 1 additional minute until fragrant, then take the pan off heat.
- 5
Fold in the whole grain mustard, fresh thyme, fresh rosemary, aged balsamic vinegar, and maple syrup into the onion mixture, then taste and adjust seasoning with sea salt and black pepper.
- 6
Unroll the thawed whole wheat puff pastry sheet onto a clean work surface and cut it into 12 equal squares or rectangles using a sharp knife.
- 7
Distribute approximately 1 tablespoon of the caramelized onion filling onto the center of each pastry piece, leaving a small border uncovered around the edges.
- 8
Scatter the shredded sharp cheddar cheese evenly over the filling on each pastry piece.
- 9
Use a pastry brush to apply the beaten egg wash along the borders of each pastry piece.
- 10
Fold each pastry square diagonally in half to form a triangle, then press the sealed edges firmly with the tines of a fork to create a tight seal.
- 11
Transfer the sealed pastry triangles to the prepared baking sheet, spacing them approximately 2 inches apart.
- 12
Brush the top surface of each pastry triangle with the remaining egg wash using a pastry brush.
- 13
Whisk together the grated Parmesan cheese and smoked paprika in a small bowl, then sprinkle this aromatic mixture evenly over all the pastry tops.
- 14
Bake in the preheated oven for 15-18 minutes until the pastries are puffed, golden brown, and crispy on the exterior.
- 15
Remove from the oven and allow to cool for 3-5 minutes on the baking sheet to set the structure before serving warm.
