Here is my recipe for zucchini and tomato flan—colorful and delicious, perfect for a summer meal with friends or family.

It’s a vegetarian and gluten-free recipe, since we’ll only be using cornstarch as a thickener.

You can serve this flan as an appetizer, as a side dish with grilled meat or fish, or even as a main course with a salad.

It’s easy to make and truly delicious.

Enjoy, and thank you in advance for your comments!

Flan de courgettes : instructions

  • 1
    Wash the zucchini and cut them into small cubes, without peeling them.
  • 2
    Rinse the tomatoes, blanch them for 30 seconds in boiling water, and peel them.
    Cut them in half, remove the flesh and seeds, then dice them into small cubes.
    Set the vegetables aside (you can mix them together).
  • 3
    In a small bowl or mixing bowl, pour in the milk, stir in the cornstarch, then add the eggs.
    Add the crème fraîche, cheese, herbs, salt, and pepper, and mix again.
  • 4
    Moisten a sheet of parchment paper (to make it easier to handle).
    Line the bottom and sides of a flan pan or individual ramekins with it.
    Note: The parchment paper will allow you to remove your flans from the pans very easily, ensuring a neat presentation and convenient serving. If you don’t have parchment paper, be sure to butter the bottom of your pans well.
  • 5
    First, layer the zucchini, then the tomatoes, and repeat for two more layers. Then
    pour the liquid mixture over the top.
  • 6
    Bake in a preheated oven (220°C) for 10 minutes. Then
    lower the temperature to 180°C and bake for another 40 minutes.
    Remove from the pan and enjoy warm or at room temperature.

    Très bonne recette, ce flan aux courgettes !

    Les propositions sont très larges (en plat principal, ça doit aller, mais en accompagnement ça fait vraiment beaucoup).
    Et je n’ai pas pu les démouler joliment comme sur la photo. 50min à 225°C comme indiqué, mais le flan n’avait pas suffisamment de consistance pour conserver la forme du moule.

      Merci Micka pour tes commentaires détaillés ! J’ai revu la recette et procédé à pas mal d’adaptations et simplifications, car cela fait longtemps que je l’avais publiée. En particulier j’ai réduit la proportion de lait, qui devait rendre le flan trop liquide en effet. Quant aux proportions globales, cela dépend effectivement de la place qu’occupe ce flan dans le repas, selon qu’on le serve en accompagnement, plat principal ou entrée. Mais il vaut mieux qu’il y en ait un peu plus que pas assez en tous cas 😋
