Instructions

1. Preheat your oven to 400°F (200°C). This will ensure that your Mini Sausage Onion Brie en Croute bakes evenly and achieves a golden-brown color.
2. Thaw the puff pastry according to package instructions. Typically, this takes about 30 minutes at room temperature. Once thawed, roll it out on a lightly floured surface to a thickness of about 1/8 inch.
3. In a skillet over medium heat, add a small amount of oil and sauté the finely chopped onion until it becomes translucent and slightly caramelized, about 5-7 minutes. Stir occasionally to prevent burning.
4. In a large mixing bowl, combine the cooked and crumbled sausage with the sautéed onions. Mix well to ensure the sausage and onions are evenly distributed.
5. On a clean surface, cut the puff pastry into squares or circles, depending on your preference. Each piece should be large enough to encase a portion of the sausage and onion mixture along with a slice of Brie cheese.
6. Place a small spoonful of the sausage and onion mixture in the center of each pastry square or circle. Top with a slice of Brie cheese, allowing some of the cheese to overlap the edges of the pastry.
7. Carefully fold the pastry over the filling to create a pocket. Pinch the edges together to seal, ensuring that no filling escapes during baking. You can use a fork to crimp the edges for a decorative touch.
8. Transfer the filled pastries to a baking sheet lined with parchment paper. Brush the tops with the beaten egg to give them a beautiful golden color when baked.
9. Bake in the preheated oven for 20-25 minutes, or until the pastries are puffed and golden brown. Keep an eye on them to prevent over-browning.
10. Once baked, remove the pastries from the oven and let them cool for a few minutes. Serve warm as an appetizer or snack, and enjoy the delightful combination of sausage, onion, and creamy Brie wrapped in flaky pastry.
