Now you can go grabbing a kitchen mandolin and rich, colorful and varied fresh vegetables: all of this is the secret to making this vegetable tian with garlic tomato sauce as delicious as you can see. That, and the Le Creuset roasting tray, new, light, resistant and fabulous for preparing all kinds of roasts.

Roasted, that is exactly what we will do with these vegetables cut and strategically placed on the tray: first, we will prepare a homemade and spaced tomato sauce, intense in flavor, which will be the base of the recipe. On top we will arrange the vegetables and, for a nice and round final touch, we will sprinkle it with cheese.

The vegetable tian is undoubtedly a classic of French gastronomy, and the one we present here is a most natural and intense tian recipe, with all the flavor thanks to the recipe for homemade and flavored tomato sauce that you will see here and that will sprinkle each bite with intense pleasure. I hope you enjoy it.

Le Creuset Roasting Tray

Ingredients (for 4-6 people)

  • 1 red onion, diced
  • 1 tbsp oil
  • 2 garlic cloves, crushed
  • 2 tablespoons dried tomato paste
  • 1 tbsp dried rosemary
  • 1 tablespoon dried oregano
  • 1/2 tbsp smoked paprika
  • 1 400g tin of chopped tomatoes
  • 2 ml of sugar
  • Sea salt
  • freshly ground black pepper
  • 1/2 lemon, grated
  • 2 green zucchini
  • 2 yellow zucchini
  • 2 eggplants
  • 2 sweet potatoes
  • 5 tomatoes
  • 30 g fresh Parmesan cheese, grated


  1. Preheat the oven to 200°C.
  2. Let's first prepare the tomato sauce. To do this, heat the oil in a Poleon Le Creuset saucepan and fry the onion over medium heat for 4-5 minutes, until it begins to soften. Then add the garlic with a pinch of salt and fry for another minute.
  3. Add the dried tomato paste, rosemary, oregano and paprika before adding all the tomatoes along with half a glass of water. Sprinkle the sugar and the lemon zest and dress before bringing to the boil for 10 minutes over medium heat, stirring occasionally, until a very thick sauce is obtained.
  4. Meanwhile, with the help of a kitchen mandolin, cut the zucchini, aubergines, sweet potatoes and tomatoes into half-centimetre slices.
  5. Put the sweet potato slices in a large bowl with a little water and put it in the microwave for two and a half minutes (we want to soften it a bit, since it is harder than the rest of the vegetables and with the time that the others require in the oven the sweet potato would be raw). Flip the slices halfway through. Then drain them well and reserve with the rest of the vegetables. In case you do not have a microwave, to soften the sweet potato you can put it in a saucepan on the fire in boiling water for 5 minutes.
  6. Let's go with the assembly of the tray. When the sauce has thickened, pour it into the base of the Ovenware Le Creuset roasting pan , distributing it well with the back of a spoon. Place the vegetables in rows, alternating each one and always following an order, until you have completely filled the tray. Depending on the diameter of the slices, you will need about four layers to fill the entire pan.
  7. Once you have everything well arranged, sprinkle the grated Parmesan on top.
  8. Put the tray in the oven for 35-40 minutes, until the vegetables have softened and the cheese is golden and crisp.
  9. Finally, take it out of the oven and let it rest for five minutes.

  • Vegetable tian is a dish on its own, which can be served as the first of a meal. Many other times it is the ideal accompaniment for meat and fish: serve a portion of tian, well arranged, on the side, as a base or topping a piece of meat or fish (either grilled or baked). You will see what a beautiful presentation you get!
  • If you choose to serve it on its own, I invite you to accompany it with a little salad: just a little arugula or spinach with cashews and a lemon vinaigrette, it will go perfectly together.
  • You can also serve it as an appetizer: pierce a few slices with toothpicks, and place them on a presenting tray to arrange in the middle of the table. You will see how quickly they disappear!
