Easy and delicious: la tarte au thon

La tarte au thon, the tuna tart, is one of those dishes that you can just assemble in five minutes and simply leave to cook in the oven. If you combine this with the fact that it is delicious, it is clearly a favourite in our house!

There are about the same number of tartes au thon recipes as the number of French households but trust me I’ve tried many, played with ingredients and proportions and this recipe is A.M.A.Z.I.N.G.!

You may then wonder… but what is the difference between a quiche and a tart? Firstly, there are eggs in the quiche filling whilst there are none in the tart. Secondly, a quiche will always be savoury whilst tarts can be either sweet or savoury.

    Oh, my husband is going to LOVE you. He used to live in France for a while (in St Nazaire) back in the 90s and when we first met, he’d tell me about this tuna tart that he had once that he loved! I’ll have to surprise him and make it for him!
