Belleau Kitchen’s Caramelised Leek Tart Tatin

This may look like you’ve slaved over this dish for hours but it is in fact such an incredibly simple tart to make. By placing butter and sugar under the leeks in the pan I've eliminated the need for pre-frying, so it can all be done in the oven. The fresh lemon thyme really brings out the flavour of the leeks, but if you can’t find any, then regular thyme also works well. So simple yet it looks so stunning.

I’ve used an oblong deep dish baking tray roughly 30cm x 20cm which is slightly smaller than a regular sheet of ready rolled puff pastry.

Serves: 4
Preparation time: 20 minutes
Cooking time: 1 hr 50 minutes

Ingredients

Roughly 8 large leeks – chopped to 3cms lengths
A few knobs of butter
Olive oil
A little golden sugar
Fresh lemon thyme
A tablespoon or two of balsamic vinegar
1 sheet of ready-made puff pastry

Pre-heat the oven to 160C (140C fan)

Directions

Lay some knobs of butter in the bottom of the pan, sprinkle with a pinch or two of sugar and plenty of fresh thyme and stand your leeks on top – they should all tuck together and stand up like little soldiers. Drizzle with olive oil and place in the oven for at least an hour, so that it gently bakes and caramelises the leeks – check after 30 mins to ensure they’re not burning.

After an hour, take it out of the oven and drizzle a little balsamic over and around the leeks, then turn the oven up to 180C (160C fan) pop it back into the oven for another 15 minutes or until softened and lightly caramelised.

Take it out of the oven and set aside to cool a little, then once it's stop steaming, lay the sheet of pastry over the top, brush with egg wash or milk and pop it back into the oven for another 20 minutes or until the pastry has risen and turned golden.

Remove from the oven and set aside for a few minutes to cool, then take a knife and ensure that the edges of the pastry are loose from the pan, then place a plate or chopping board over the pan and quickly flip the whole thing upside down and remove the pan.
