Delicious little morsels, full of flavour and texture. Can you stop at one?

Makes: 36 tartlets


  • 1 1/2 cup (215g) plain flour
  • good pinch of salt
  • 125g cold butter, cut into 1cm cubes
  • 1 egg yolk
  • 2 tspn – 1 tbspn ice cold water
  • 2 tbspn extra virgin olive oil
  • 2 onions, thinly sliced
  • 1 tspn brown sugar
  • 1/4 cup thickened cream
  • 2 eggs, lightly beaten
  • 50g blue cheese, finely crumbled
  • parsley leaves, to garnish


  1. Pre-heat oven to 220°C (200°C fan forced).
  2. Process flour, salt and butter in a food processor until mixture is of a crumbly consistency. While the motor is running, add the egg yolk and enough water to allow the mixture to form a ball. Knead lightly on a floured board to form a smooth ball. Flatten slightly and wrap in plastic wrap. Refrigerate for 30 minutes or until required.
  3. Meanwhile, heat oil in a large non-stick frying pan. Add onions and cook over low heat for 15 minutes or until golden brown. Add sugar and continue to cook for a further 2 minutes. Remove from heat and allow to cool.
  4. Place cream, eggs and blue cheese into a mixing bowl and mix to combine.
  5. Roll out dough between two sheets of baking paper to a 1-2mm thickness. Using a 5 1/2cm round fluted cutter, cut dough into rounds and line a  Mini Tartlet Pan, pressing the dough into the corners and sides of the pan using a small ball of dough. Re-roll remaining dough cuttings into a ball, cover with plastic wrap and refrigerate until required.
  6. Place a small amount of onions into the base of the tartlets. Pour 1-2 teaspoons of egg mixture over onions and bake for 12 – 15 minutes or until golden. Allow to cool and garnish with parsley leaves.
  7. Once the pan has cooled completely, repeat with remaining ingredients.
  • Oh wow! These look and sound amazing! Will definitely try these for my next party!


  • Yum, onion and blue cheese makes my mouth water ! I would probably use lentil flour instead of plain flour to make it gf and a richer in nutrients. I’m not keen on using sugar, but that’s easy to leave out :)


  • Mmmm onions and blue cheese are 2 of my favourites !


  • These sound so gourmet and indulgent :)


  • I’m not a fan of blue cheese but could easily replace it with something else. I love the idea of these.


  • Great choice of ingredients! I love blue cheese!!


  • These look so tantalising and simple to make.


  • Ooh yummy, these look so nice.


  • I already have the silicone moulds! What cute little moulds of yumminess. Can’t wait to try these.


  • I’ve only just started using silicone moulds and now wish I’d started sooner. I think with this recipe I’m going to be quite popular. Thanks


  • I love baking with silicone molds, it’s very practical, easy clean and non-stick indeed.

    • I love onion blue cheese tarts too :) !!


  • I’ll be trying this.


  • Bianca, these tarts sound incredibly tasty…


  • I do have silicone bakeware but I don’t often use it. I love these tartlets. Imagine I could replace the blue cheese though – I can’t stand the smell of it.


  • I never realised that Silicone was such a big deal! I didnt particularly like it. It never washed well for me
