Instructions
-
1
Preheat the oven to 190°C (375°F). Wash and thoroughly dry all the vegetables.
-
2
Prepare the aromatic base: peel and finely slice the onions. Sauté them in a skillet with 2 tablespoons of olive oil for 10 minutes over low heat until soft and translucent. Add the minced garlic at the end of cooking.
-
3
Spread the caramelized onions on the bottom of a gratin dish (or traditional terracotta tian). Sprinkle with thyme leaves and a few basil leaves.
-
4
Cut the zucchini, tomatoes, eggplant and remaining onion into even slices about 3 to 4 mm thick.
-
5
Arrange the slices in tight, alternating rows (zucchini, tomato, eggplant, onion) over the caramelized onion base, tilting them slightly. Fill the dish compactly.
-
6
Drizzle generously with olive oil, season with salt and pepper, and sprinkle with fresh thyme and rosemary. Tuck the unpeeled garlic cloves between the vegetables.
-
7
Cover with aluminum foil and bake for 30 minutes. Then remove the foil and continue cooking for 20 minutes uncovered so the vegetables brown on top.
-
8
Remove the tian from the oven, sprinkle with freshly chopped basil and a drizzle of olive oil. Let rest for 5 minutes before serving.
Chef's tips
Use a mandoline to cut the vegetables into perfectly even slices — that's the secret to a visually stunning tian. If the vegetables release a lot of water during cooking, switch to broil mode for the last 5 minutes to gratinate them. You can add slices of fresh goat cheese on top near the end of cooking for a more indulgent version.
Additional information
The tian is a Provençal vegetable gratin whose name comes from the earthenware dish in which it is traditionally prepared. Visually spectacular with its vegetable slices arranged in a perfect rosette, the tian is proof that simple cooking can be remarkably beautiful. It is a dish that celebrates summer and the generosity of the Mediterranean garden.
The Art of Arrangement
What sets the tian apart from a simple ratatouille is the careful arrangement of the vegetables. The slices of zucchini, tomatoes, eggplant and onions are alternated in tight rows, slightly tilted against each other, forming a regular and harmonious pattern that gives the dish all its elegance.
To achieve a visually perfect result, choose vegetables of similar diameter. This is why medium-sized zucchini and standard round tomatoes are preferable. The slices should be cut to the same thickness — about 3 to 4 mm — for even cooking and a regular appearance.
The Aromatic Base
Beneath the rows of vegetables lies a meltingly soft aromatic base that makes all the difference: a blend of caramelized onions, garlic and fresh herbs that flavors the vegetables from below during cooking. This layer also absorbs the juices released by the vegetables, forming a savory compote at the bottom of the dish.
Olive oil plays an essential role in the tian. It nourishes the vegetables, prevents them from drying out and promotes the caramelization that gives the dish its appetizing roasted flavor. Don't be shy: a good tian should be glistening and lustrous, with each vegetable slice golden and tender.
A Versatile Dish
The tian can be served as a vegetarian main course, accompanied by rice or creamy polenta, or as a side for grilled meat or fish. It is delicious hot, straight from the oven, but also at room temperature for a relaxed summer lunch. With a drizzle of balsamic vinegar and a few shavings of Parmesan, it transforms into a refined appetizer.
The tian lends itself particularly well to meal prep: prepare it on the weekend and reheat in the oven during the week. It keeps for 3 to 4 days in the refrigerator and its flavors improve over time.
