Thaw the puff pastry in the fridge overnight, until pliable but still cold.
Refrigerator
💡Work with store-bought dough while it's cold: warm puff pastry gets sticky and won't puff in the oven, and phyllo sheets dry out fast, so keep the waiting sheets covered with a damp towel.

In a bowl, mix the mashed potato, white cheese, yellow cheese, eggs, nutmeg and fried onion, and season with salt and black pepper.

3
Preheat the oven to 180°C (355°F).
⚙ Preheating the OvenOven
💡Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
4
Lay the filling along the dough, close to the edge, and roll up into a tight log.
💡Roll tightly and leave a clear border at the far edge: a loose log opens in the oven, and the filling escapes.
5
Arrange on a baking sheet lined with parchment paper, spaced apart, and brush with beaten egg and sprinkle the sesame seeds on top.

💡Check by the cue (until…), not just the clock: every oven bakes a little differently.
