I used a 23cm diameter deep flan tin for this tarte but use what you have.
Roll out your flour, line the tin and blind bake the pastry case for about 15minutes
Remove your baking beans and cook for another 5 minutes
Reduce the oven temperature to 180c/160c fan/gas 5
In a dry pan fry the lardons until golden then add the onions, cook for a further 5 minutes or until the onions turn transparent
Allow mixture to cool slightly
Once your pastry case is partially cooked (blind baked) you can start layering the tarte.
Start with a layer of potato, season then sprinkle with lardon/onion mixture and a layer of chives and grated cheese
Continue layering until you reach the top of the pastry. Don’t go too high, you’ll need to leave a bit of space for the eggs to rise.
Whisk the eggs into the milk until combined then pour mixture onto the filling until it reaches the same level as your last layer.
Sprinkle with a final bit of grated cheese then bung it in the oven for about 25-30 minutes or until eggs are puffed up and golden
Serve either warm or cold with a crisp green salad tossed with yummy French dressing and have a glass of your favourite wine at hand
