Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

• 2 medium zucchini
• 2 medium potatoes (Yukon Gold or red)
• 2 medium tomatoes
• 1 medium eggplant
• 2 tablespoons olive oil
• 1 onion, finely chopped
• 2 garlic cloves, minced
• 1 teaspoon dried thyme (or a few sprigs of fresh thyme)
• Salt and pepper to taste
• 1/3 cup grated Parmesan or Gruyère cheese (optional)

Directions

1. Preheat oven to 375°F (190°C).
2. Lightly grease a medium baking dish or cast iron pan with olive oil.
3. In a skillet over medium heat, sauté the chopped onion and minced garlic in 1 tablespoon olive oil until soft and translucent, about 5 minutes. Spread this mixture over the bottom of the baking dish.
4. Using a mandoline or sharp knife, slice the zucchini, potatoes, tomatoes, and eggplant into uniform 1/8-inch thick rounds.
5. Arrange the sliced vegetables upright in the baking dish in a repeating pattern (zucchini, potato, tomato, eggplant), forming concentric circles or rows, depending on the shape of the dish.
6. Drizzle the remaining tablespoon of olive oil evenly over the vegetables. Season generously with salt, pepper, and thyme.
7. Cover the dish with foil and bake for 35 minutes.
8. Remove the foil, sprinkle with grated cheese if using, and continue baking uncovered for 25–30 minutes, until the vegetables are tender and the top is golden and bubbling.
9. Let rest for 10 minutes before serving. Garnish with fresh thyme if desired.

FAQs

Can I prepare the tian in advance?

Yes, you can assemble the tian a few hours or even a day in advance. Cover and refrigerate, then bake when ready to serve.

What’s the best way to slice the vegetables evenly?

A mandoline slicer is ideal for creating uniform, thin slices that cook evenly.

Can I freeze vegetable tian?

Freezing is not recommended as it may affect the texture of the vegetables after thawing.

What should I serve with this dish?

It pairs well with roast chicken, grilled fish, or a simple green salad for a light, balanced meal.

Can I use different vegetables?

Absolutely. Feel free to incorporate yellow squash, leeks, or even beets for variety.

How do I prevent the potatoes from undercooking?

Ensure the slices are thin and even. You can also parboil the potatoes briefly before layering if desired.

Is this dish vegan without cheese?

Yes, it becomes entirely plant-based when the cheese is omitted or replaced with a vegan alternative.

Can I cook this at a higher temperature to save time?

A slower bake helps the vegetables soften and caramelize evenly. A higher temperature may cause uneven cooking or burnt edges.

What is the origin of the name “Tian”?

“Tian” refers both to the dish itself and the type of earthenware vessel traditionally used to cook it in Provence, France.

Can I use canned tomatoes instead of fresh?

Fresh tomatoes are recommended for texture and appearance. Canned tomatoes are too soft and will not hold their shape.
