Step-by-Step Instructions

1. 1.Prepare the Pastry Sheets

   Open the package of ready-made pastry sheets. Roll them up and cut them into small strips, then separate them into individual pieces. Set aside.

2. 2.Prepare the Spinach Filling

   In a bowl, combine the spinach, a drizzle of olive oil, and a pinch of salt. Press and mix the spinach well with your hands for a few minutes until it wilts. Add the crumbled feta cheese and mix thoroughly.

3. 3.Prepare the Milk Mixture

   In a separate measuring cup or bowl, combine the milk, eggs, 50ml of olive oil, and a pinch of salt. Whisk well until all ingredients are fully combined.

4. 4.Assemble the Burek

   Line a baking tray with parchment paper. Spread about one-third of the cut pastry strips evenly on the bottom of the tray. Pour a portion of the milk mixture over the pastry to soften it. Spread half of the spinach and feta filling over this layer. Add another third of the pastry strips, pour more milk mixture, and then spread the remaining spinach filling. Finally, cover with the last third of the pastry strips and pour the remaining milk mixture evenly over the top.

5. 5.Add Butter and Bake

   Place small pieces of butter evenly over the top layer of the burek. Preheat your oven to 180°C (350°F). Bake the burek for approximately 30 minutes, or until golden brown and cooked through. Baking time may vary depending on your oven.

6. 6.Serve

   Once baked, remove the burek from the oven and let it cool slightly. Cut it into squares and serve warm. Enjoy!
