Ingredients
Equipment
Method
- Preheat your oven to 200°C (390°F). Line a baking sheet with parchment paper and keep your puff pastry cold and ready.
- Cook the bacon in a skillet until crispy, then drain on paper towels and chop into small pieces. In the same skillet, caramelize the sliced onion until golden and sweet, then let it cool slightly.
- Unfold the cold puff pastry sheet onto a lightly floured surface. Using a sharp knife or pizza cutter, cut the pastry into 24 small squares, about 4×4 cm (1.5×1.5 inches).
- Arrange the pastry squares on the prepared baking sheet, spacing them about an inch apart. Keep the sheet chilled until you’re ready to fill.
- Place about a teaspoon of caramelized onion and a few bits of bacon onto the center of each square. Spread a small dab of Dijon mustard on top of the fillings.
- Using a pastry brush, lightly brush the edges of each square with the beaten egg to give a shiny, golden finish when baked.
- Sprinkle shredded cheese evenly over each filled square, then add a pinch of chopped herbs for fresh flavor. Optionally, top with sea salt or poppy seeds for crunch and visual appeal.
- Bake in the preheated oven for 15-18 minutes, until the pastry is puffed, golden, and crispy, and the cheese is bubbling.
- Once baked, remove the tray from the oven and let the bites rest for 5 minutes to set the fillings and crisp up further.
- Serve these rustic bites warm, arranged on a platter, and enjoy the flaky, cheesy, savory goodness with your favorite drinks.
