Albanian Byrek with Slow-Roasted Meat and Cheese

Method

1. Preheat oven to 180°C (350°F). In a large oven-safe skillet, heat olive oil and brown the ground beef and lamb together over medium-high heat.
2. Once browned, add the onion and cook until softened, about 5 minutes. Stir in the beef broth, salt, pepper, paprika, cumin, and garlic powder.
3. Cover the skillet and simmer for 45 minutes, allowing the meat to slowly roast in its own juices, tenderizing the mixture.
4. After 45 minutes, stir in the feta cheese and let it melt into the mixture. Remove from heat and let cool slightly.
5. Roll out the puff pastry and cut into a large rectangle. Spread the meat and cheese mixture over the pastry, leaving a 1-inch border.
6. Fold the edges of the pastry over the filling and brush with the beaten egg.
7. Bake for 25-30 minutes until golden brown and crispy.
8. Check that the ground meat reaches 71°C (160°F) throughout before serving.
