Onion Tart with Rocket and Cheddar

The key to success with this tart is to make sure you have plenty of onion filling. If there’s too much egg and not enough onion you end up with an omelette instead of a tart. Make this in a tart tin or cut the pastry into an oblong and cook on a baking sheet.

For how many? Serves 4

  • 250g shortcrust pastry (see ingredients below)
  • 1 tbsp olive oil.
