Thermomix flan patissier aka custard tart a la French – simply deliiiicious!

This Thermomix recipe for flan patissier (French custard tart) makes a tart that is simply exquisite, firm yet creamy, we just can’t get enough of it in our family.

After dozens of failed or second best attempts at flan patissier (sometime without a Thermomix), I am so glad I have found this recipe.

I am looking forward to hearing about how you get on with it. Feel free to leave a comment below.

  11. Pour the cream mixture into the pastry case and bake for 30 minutes at 180C.
  12. Let cool down for at least 2 to 3 hours before tasting. Good luck with that part of the recipe!!

I sometimes add raisins, prunes or other dried fruits before pouring the mixture into the pastry. Tastes just as good and kids love the surprise effect!

Delicious. Bon appetit x
