Heat part of the olive oil in a pan and fry the onion with the sugar, salt, black pepper and thyme over low heat 20–25 minutes, stirring, until it is deep brown.
StoveFrying pan
💡Onion caramelizes with patience: over medium heat it reaches deep brown in about half an hour, over low heat it takes close to an hour, and over high heat it burns at the edges before it softens. A pinch of salt at the start draws out its liquid, and when it starts to stick, add a tablespoon of water and scrape the bottom.
To assemble
2
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.
3
Beat the eggs and cream and add the feta cheese and the caramelized onion.
💡The onion goes into the filling soft and golden: in the oven it won't soften any further, and raw onion releases liquid into the crust.
4
Line tartlet pans with layers of phyllo, brushing each layer with the rest of the olive oil.

5
Fill the phyllo shells with the filling.

Bake 20–25 minutes, until the filling is set and the phyllo is browned.
