Onion flan
Preparation time
Cooking time
Total time
This easy onion flan can be made with or without pastry. The recipe is for the filling: if you want pastry, make and blind bake this separately. A Boston pastry (flour, oil and water) works well, especially if you use rye or buckwheat flour as well as wheat.
Recipe type: Flan
Cuisine: Vegan
Serves: 4-8
  • 500 grm onion
  • 500 grm leeks
  • 2 tbsp olive oil
  • 400 grm silken tofu (one block)
  • 100 ml soya milk
  • 2 tbsp nutritional yeast (optional)
  • A good shake of nutmeg (optional)
  • Chilli flakes to taste (optional)
  • 1-2 cubes fermented tofu (optional)
  • 1 tbsp soy sauce
  • Salt and pepper
  1. Pre-heat the oven to 200C (180C fan).
  2. Trim and finely slice the onions and leeks.
  3. Heat the iol in a pan and add the onions and leeks.
  4. Cook until caramelised, 30-40 minutes depending on the heat. You want ot brown but not burn or dry out the veg.
  5. In a separate bowl or a stick-blender mixer attachment, mix tofu, milk and flavourings until smooth.
  6. When the onions are done, mix the tofu mixture into them.
  7. If using a pastry case, pour the mixture into the case and even out the top. Else pour into a well-greased or non-stick case.
  8. Cook for 30-40 minutes, or until set and golden brown on top. The longer time gives a darker more caramelised top.
  9. Remove from oven and let rest for a few minutes.
  10. Serve with salad and, if your diners are hungry, bread on the side.
