Tepsi böreği is a popular type of Turkish börek, essentially a savory pastry made by layering sheets of phyllo pastry with a filling. The filling can be almost anything, but typically it will be either seasoned ground beef or lamb with onions or potatoes, spinach, or cheese.
Each layer of pastry is brushed with melted butter or oil before adding the filling and the next layer. Once the pastry is assembled, it can be brushed with an egg wash or yogurt. Tepsi böreği can be cooked two ways, either in the oven or on the stove, in which case, the pastry should be flipped so it bakes on both sides.
This recipe shows the classic preparation of tepsi böreği that has a spinach filling. The recipe is adapted from the gastronomy book Turkish Cuisine With Timeless Recipes.
