Preheat the Oven: Preheat your oven to 350°F (175°C). Prepare a baking sheet by lining it with parchment paper or lightly greasing it with butter.
Prepare the Pastry Cups: If using mini phyllo pastry cups, place them on the prepared baking sheet. If using puff pastry shells, bake them according to the package instructions to make them crisp and golden.
Prepare the Filling: In a small bowl, combine the fresh blueberries, lemon zest, lemon juice, and honey. Gently mix until the blueberries are well-coated, creating a fresh, sweet filling.
Assemble the Bites: Place a small cube of Brie cheese into each phyllo cup. Then, spoon about a teaspoon of the lemon-blueberry mixture over the cheese. If you'd like, you can add a little sprinkle of sea salt to enhance the flavors.
Bake the Bites: Place the assembled bites in the oven and bake for 10-12 minutes, or until the Brie is melted and bubbly, and the pastry is golden brown.
Garnish and Serve: Once out of the oven, drizzle the bites with a little extra honey for a touch of sweetness and garnish with fresh thyme for an aromatic finish.
Serve immediately and watch as these delicious Lemon-Blueberry Brie Bites disappear quickly!
