This tomato tart with caramelised red onions is very simple to prepare and makes the most of the different varieties of tomatoes in season. The sweet caramelised onions bring out the natural flavour of the tomatoes to give a delicious and crowd-pleasing tart that is the perfect dish for al fresco lunches or a late summer dinner party starter. Once you’ve made your caramelised onions, which can be prepared in advance, this tomato tart couldn’t be easier to prepare. Ready made puff pastry can be bought in most supermarkets and is much less of a hassle than making your own. The all-butter varieties give the best results, but pastry made with margarine can be used to make this recipe suitable for vegans.
British tomatoes are in season from June until October, and this tomato tart is a great way to use up a surplus of seasonal tomatoes. Our recipe for delicious slow roasted tomatoes is another great way to celebrate this healthy and flavour packed ingredient. For more ideas with tomatoes have a look at our tomato recipe collection.
