Spinatstrudel (Spinach Strudel)

1 . Stage

Preheat oven to 425 degrees F (220 degrees C). Line a baking sheet with parchment paper.

2 . Stage

Mix spinach, Parmesan cheese, cottage cheese, sour cream, shallots, 1 egg, garlic, salt, black pepper, and nutmeg together in a bowl until filling is well-mixed.

3 . Stage

Roll puff pastry onto a clean work surface, a little thinner at the edges. Transfer to the prepared baking sheet.

4 . Stage

Spoon the filling down the middle length of the pastry sheet. Crack 1 egg into a cup but do not beat it. Brush the edges of the puff pastry with egg white and close the pastry around the filling. Close the ends of the roll and carefully turn it over so the seam is on the bottom.

5 . Stage

Beat what remains of the egg; brush over the top of puff pastry and cut a few slits in the pastry.

6 . Stage

Bake in the preheated oven until the strudel is golden brown, about 30 minutes.
