About the bake

These roasted balsamic red onion and feta tarts provide the perfect baking inspiration. These are delicious little savoury tarts and perfect to serve as a starter when entertaining at home. We walk you through the steps below to make open pastry cases from ready rolled shortcrust pastry although if you wanted to make your own pastry cases you will have to add on around 30 minutes of prep and baking time.

  1. Step 1:

    Preheat the oven to 190°C (170°C fan, gas mark 5).

  2. Step 2:

    Place the onions on a non stick baking tray, sprinkle with light muscovado sugar, oil, chillies and season well.

  3. Step 3:

    Roast in the oven for 20 minutes, remove and mix through the balsamic vinegar, and allow to cool.

  4. Step 4:

    Unroll the pastry and using a rolling pin roll out the pastry a little more to cut out four 15 cm (6 in) circles, place on a lined baking sheet.

  5. Step 5:

    Mix the onions gently with the thyme, feta and walnuts, and spoon the onion mixture evenly between the pastry circles, leaving a 2 cm (¾ in) border.

  6. Step 6:

    Bring the edges of the pastry up around the sides of the onions forming an open tart, and glaze with the beaten egg.

  7. Step 7:

    Sprinkle over some light muscovado sugar and dried crushed chillies over each tart and bake for 20 minutes until golden.

  8. Step 8:

    Top with the dressed rocket leaves and serve.
