Caramelised onion tart

Caramelised onion tart

This Caramalised onion tart is a simpler version of a quiche, just with fewer ingredients. This can be served hot or cold with a nice green salad and mayonnaise. To save some time the Shortcrust pastry can be bought ready made or if you are unorganised as me, it is easy to make. A variety of white/red onions and shallots can be added to this recipe for variation but I find the simpler the recipe the less food shopping I have to do.


  • 200g Plain flour
  • 100g Butter
  • 2 Onions, peeled and sliced
  • 1 tsp Dried Thyme
  • 3 Eggs
  • 150ml Milk
  • 100g Chedder cheese
  • 1 garlic clove, peeled and diced
  • 2 tbsp Sugar


  1. First make the dough, rub the butter and flour together until it resembles fine breadcrumbs.
  2. Add approx 2 tbsp of water and mix in until well combined.
  3. Cover and leave aside in the fridge for about 30 minutes.
  4. Next fry the onions until soft and add in the garlic and sugar in the last few minutes to caramalise.
  5. Then preheat the oven to 180 degrees, grease a flan dish and roll out the dough until it is slightly larger.
  6. Place the dough into the flan dish, press down and trim off excess.
  7. Put some grease proof paper and baking beans on top and pop into the oven for about 15 minutes.
  8. Remove the paper and beans, brush some milk on top of the pastry and pop back into the oven for about another 5-10 minutes until lightly golden.
  9. Once cooked place in the onions and garlic mixture and spread evenly on base.
  10. Then beat the eggs, thyme, cheese and milk and pour over the onions.
  11. Pop back into the oven for another 20-25 minutes until golden on top.
