Vegetable Tian Recipe Ingredients
- 1 head garlic, separated into cloves with all but 1 clove unpeeled
- ⅓ cup extra-virgin olive oil
- 1 yellow squash, about 6 ounces, thinly sliced crosswise
- 1 small Japanese eggplant, about 6 ounces, thinly sliced crosswise
- 1 zucchini, about 6 ounces, thinly sliced crosswise
- 4 plum tomatoes, about 1 pound, sliced into ¼-inch thick rounds
- 1 medium red onion, thinly sliced crosswise
- Coarse salt and freshly ground pepper
- Sprigs of thyme, rosemary, oregano, or marjoram
How To Make Vegetable Tian
- Prep the oven and dish: Preheat the oven to 400°F. Peel one clove of garlic, cut it in half, and rub the cut side all over the bottom of a 2-quart baking dish. Pour 2 tablespoons of the olive oil into the bottom of the dish.
- Arrange the vegetables: Arrange the thinly sliced yellow squash, eggplant, zucchini, tomatoes, and red onion in the baking dish, alternating them in an overlapping pattern. Season with salt and pepper as you layer them.
- Add final touches: Scatter the fresh herb sprigs and the unpeeled garlic cloves over the top of the vegetables. Drizzle with the remaining olive oil.
- Bake until tender: Bake for 25 minutes. Baste the vegetables with the oil from the bottom of the pan, then continue baking for about 25 more minutes, until the vegetables are tender and browned.

Recipe Tips
- How to get perfectly cooked vegetables? The key is to slice all the vegetables to a uniform, thin thickness (about ¼-inch). This ensures they all cook evenly and become tender at the same time. A mandoline can be very helpful for this.
- Can I use different vegetables? Yes, this dish is very adaptable. Thinly sliced potatoes, bell peppers, or fennel would also be delicious additions.
- What’s the purpose of the unpeeled garlic? As the garlic roasts in the olive oil, it becomes incredibly soft, sweet, and creamy. You can squeeze the roasted garlic out of its peel and spread it on crusty bread alongside the tian.
- Can I make this ahead of time? You can assemble the entire tian in the baking dish, cover it, and refrigerate it for up to a day before baking. You may need to add a few extra minutes to the baking time.

How To Store Vegetable Tian
- Refrigerate: Store leftover tian covered or in an airtight container in the refrigerator for up to 4 days. It’s delicious served at room temperature or gently reheated in a 325°F oven.
- Repurpose: Leftover roasted vegetables are fantastic tossed into a frittata, added to a grain bowl, or layered into a sandwich with fresh mozzarella and pesto.
