This bacon tart recipe is the perfect Autumn lunch. We love a good puff pastry tart recipe because of the ease and speed to make them, but this bacon and leek tart recipe takes it one step further with sweet caramelised leeks and crispy bacon. The secret to this bacon onion tart recipe is our deliciously smokey Double Smoked British Bacon, which gives this tart recipe with bacon a glorious depth to the flavour. Give this Autumn tart recipe a try for your next easy but delicious lunch.
