We eat this leek, pesto and olive tart a lot. It basically involves frying up some leeks and thyme and then piling the leeks with pesto, grated cheese, and olives on top of ready made puff pastry and popping it into the oven. We have eaten it so much I could probably make it blindfolded, it’s one of our real staples. I’ve served it with a salad, or when we are hungry with jacket potatoes too. It looks good enough to serve with friends. But if it’s just Dave and me it’s great reheated the following night – just cover it with foil and put it in the oven at 200 C for 20 minutes to heat through. If you are starving and can’t wait for the oven you can heat it in the microwave and although you’ll end up with soggy pastry, it’s still very edible. I love recipes that feed Dave and I for two nights.

The first thing I do to make this leek pesto and olive tart is to take the pastry out of the fridge and out of the box so it can come up to room temperature which makes it less lightly to tear. Then I get the leeks frying away, they take about ten minutes to become sweet and silky. I fry them in butter for the taste and a drizzle of oil to help stop the butter from burning. While they are cooking I unroll the pastry and lay it out. I always use the ready rolled pastry in baking paper which makes it easy to place the paper and pastry straight onto a large baking sheet. I cut the sides of the pastry to make a little ridge.

Then I coat the pastry inside the ridge in the pesto. Dave isn’t a fan of green pesto, so I always use red and generally sun dried tomato pesto, but it would work well with green, or with whatever pesto you have in the cupboard. The cooked leeks go on top of the pesto. Then I top with the olives and grated cheese and pop in a preheated oven. That’s it get ready for your leek, pesto and olive tart!

Once cooked, I give it ten minutes on the side to cool a little before serving as this enables the full flavour to develop.
