Tips
Cool leeks before assembly to prevent pastry from becoming soggy.
Keep 3cm border clear so edges can puff up and crisp properly.
Check tart at 18 minutes; oven temperatures vary.
Good to Know
Cover and refrigerate up to 2 days. Reheat in 160C oven for 10 minutes.
Assemble tart (through cheese and filling stage) up to 4 hours ahead. Fold pastry edges and bake just before serving.
Serve warm or at room temperature. Pairs with simple green salad.
Common Mistakes
Do not skip cooling leeks to avoid soggy pastry base.
Do not overfill beyond the 3cm border to avoid filling leaking and preventing edge puffing.
Do not use cold leeks straight from pan to avoid uneven cheese melting.
