Vegetables are the biggest challenge for us as parents: preparing them in a tasty and appetising way to win children over is not always easy. The Three-colour flan can be a winning idea as it contains some of children’s favourite vegetable ingredients, namely potatoes, pumpkin and carrots.

Given the richness of potatoes and pumpkin in carbohydrates, as well as the presence of cheese and egg, the Three-colour flan can be eaten as a one-course meal, quenching even the most insatiable appetites.

Furthermore, you can also use this wonderful dish as a side dish or, why not, a main course to propose during a dinner with friends with vegetarian preferences, perhaps combined with a Ratatouille.

Steam the pumpkin and thinly sliced courgettes with a little oil and salt. Once the pumpkin is cooked, repeat the operation with a potato masher, add the carrots, a little Parmesan cheese, salt to taste, and complete the mixture with some mashed potatoes.
  2. Form a layer of courgettes on the bottom of an oven-proof dish and sprinkle with the remaining Parmesan cheese. Cover everything with the pumpkin mixture, press well and top with a layer of mashed potatoes.
  3. Dust the surface with a little breadcrumbs, put a few tufts of butter on top and bake au gratin in the oven at 200°C for about 20 minutes, until a nice crust has formed. Serve the flan warm or lukewarm.
