    While the onion is cooking, dust bench with flour. Roll pastry out to 22cm x 32cm. Transfer to baking tray and score a 1cm border around the edge with a knife, taking care not to cut all the way through the pastry. Prick base with a fork. Brush edges with beaten egg, if using.

    Stir the mustard into the crème fraîche and spread over the base. Top with onion and apple mixture and bake for 25 minutes or until pastry is dark golden and crisp. This can be served warm or cold.


  • If you would prefer a meat option, add a couple of sliced cooked sausages to the topping. The egg is optional but makes the pastry a rich golden colour. PER SERVE Energy 577kcal, 2418kj • Protein 9g • Total Fat 37.5g • Saturated Fat 18.7g • Carbohydrate 48g • Fibre 7g • Sodium 262mg
