Onion Tartlets Recipe

onion tartlets recipe

Writing about food in literature in my Feasting on Romantic Comedy column for Novelicious I researched, adapted or created many recipes. My favourite recipes were those that were simple. Or ones that surprised me when I was experimenting.

These onion tartlets did both. So simple to make and tasting surprisingly delicious. I could have eaten all of them but unfortunately my husband enjoyed them, too.

Simple and Easy Recipe for Onion Tartlets


  • Large frying pan or pan with lid
  • Sharp knife
  • Baking tray covered with baking parchment
  • Pastry brush


  • One pack ready rolled puff pastry
  • Knob of butter
  • Glug of olive oil
  • About ten small onions, sliced
  • 1 tsp sugar
  • Salt
  • Fresh thyme
  • Egg


  1. Heat the pan with the olive oil and add the sliced onions. Stir in the butter, then reduce heat to low and cover with the lid. Cook for ten minutes.
  2. Remove the lid, stir in the sugar and season with the salt and cook for another ten minutes with the lid off until all the liquid has gone.
  3. Pre-heat oven to 200 degrees fan.
  4. Unwrap the pastry and divide into small rectangles with a sharp knife. You can make them as small or large as you wish. (Though, obviously, not too small!) Place onto the baking sheet/s.
  5. Place the caramelised onions in the centre of the rectangle, leaving a gap around the edge.
  6. Sprinkle with fresh thyme.
  7. Beat the egg with a fork and use a pastry brush to paint the egg around the edge of the rectangle on the pastry.
  8. Place in the oven for 20 minutes.
  9. Remove and serve warm or cold.

    They sound yummy. I make something similar, I sprinkle grated goats cheese on top of the slow cooked onions. 😉
