How to Make Zucchini Tian (Naturally Healthy) Recipe
Step 1: Prepare the Zucchini and Onion
Start by thinly slicing the zucchini—aim for uniform rounds so they cook evenly. In a skillet, gently sauté your finely diced onion and minced garlic in a tablespoon of olive oil over medium heat until they’re soft, fragrant, and golden. This step ensures that the sweet and savory aromas are beautifully locked into the dish from the start. Once the zucchini is sliced, sprinkle a little salt over it and let it sit for about 10 minutes to draw out excess moisture, which you’ll collect later for the cooking liquid.
Step 2: Make the Creamy Base
Collect the zucchini juices by pressing the salted slices with your hands or using a fine sieve. Combine these juices with warmed milk in a saucepan. Then, whisk in the flour and the uncooked rice along with salt and pepper. Stir constantly over medium heat until the mixture thickens slightly. This forms the luscious, velvety sauce that will hold the layers together while allowing the zucchini to stay tender but distinct.
Step 3: Assemble and Bake
Preheat your oven to 180°C (350°F). Lightly grease a baking dish with the remaining olive oil. Arrange the zucchini slices vertically, alternating with layers of sautéed onion and garlic mixture. Pour the creamy sauce over the layered veggies, then finish by sprinkling the grated parmesan evenly on top. Pop it into the oven and bake for about 45 minutes, until the top is golden brown and bubbly. You’ll know it’s ready when the edges are slightly crisp and the rice is tender.
How to Serve Zucchini Tian (Naturally Healthy) Recipe

Garnishes
A sprinkle of fresh herbs like thyme, rosemary, or parsley brightens this dish beautifully—plus, a light drizzle of extra virgin olive oil right when it’s out of the oven adds gloss and a touch of luxurious flavor. For an extra pop of texture, some toasted pine nuts scattered on top create an irresistible crunch that complements the creamy layers.
Side Dishes
Zucchini Tian (Naturally Healthy) Recipe pairs wonderfully with light, fresh sides. A crisp green salad with lemon vinaigrette or a handful of olives and crusty whole-grain bread make great companions. If you want something heartier, serve it alongside grilled chicken or baked fish for a balanced, flavorful meal.
Creative Ways to Present
For an elegant presentation, try serving individual portions by baking the tian in small ramekins—each person gets a personal, perfectly crisped casserole. Alternatively, layer the zucchini mixture in a glass casserole dish or even in a pie crust for a zucchini tart twist that surprises and delights every time you serve it.
Make Ahead and Storage
Storing Leftovers
This zucchini dish keeps wonderfully in the refrigerator for up to 3 days. Simply cover it tightly with foil or plastic wrap to preserve moisture and prevent any fridge odors from sneaking in. When you’re ready to indulge again, reheat gently to keep the creamy texture intact.
Freezing
If you want to make this dish ahead for a busy week, you can freeze it in airtight containers for up to 2 months. It freezes best before baking—just assemble your layers in a freezer-safe dish and wrap well. When ready to eat, thaw overnight in the fridge and bake as usual, adding a few extra minutes to the cooking time.
Reheating
To bring your leftovers back to life, reheat the zucchini tian gently in a 160°C (325°F) oven until warmed through—about 15 to 20 minutes. Avoid the microwave if possible, to keep the layers from becoming too soggy and maintain that perfect tender bite.
FAQs
Can I use other vegetables in this zucchini tian recipe?
Absolutely! While zucchini is the star, feel free to mix in thin slices of eggplant, tomatoes, or bell peppers for extra color and flavor. Just be mindful of moisture content to maintain the right texture.
Is it necessary to use rice in this dish?
The rice helps to thicken the creamy base and adds substance, making the dish more filling. If you’re looking for a gluten-free option, make sure to use rice flour instead of regular flour, or adjust the thickening agent accordingly.
Can I make this recipe vegan?
Yes! Substitute the parmesan cheese with a vegan cheese alternative, and use plant-based milk instead of dairy milk. The olive oil and vegetables keep the dish naturally rich and satisfying.
How thin should I slice the zucchini?
Try to slice the zucchini about 1/8 inch thick so that it cooks evenly and layers nicely in the baking dish. Uniform slices ensure that every bite has the perfect balance of tenderness and texture.
What can I serve with Zucchini Tian (Naturally Healthy) Recipe for a complete meal?
This dish pairs beautifully with a light protein like grilled fish or roasted chicken. Adding a simple green salad or steamed grains rounds out the meal with freshness and crunch.

Description
This Zucchini Tian is a naturally healthy, comforting baked dish featuring thinly sliced zucchini layered with a savory mixture of onions, garlic, parmesan cheese, and rice. Lightly enriched with milk and warm zucchini juices, this flavorful casserole combines Mediterranean influences with wholesome ingredients to create a satisfying vegetable gratin suitable for a nutritious family meal.
Ingredients
Zucchini Tian
- 1 kg (2 lb) zucchini, thinly sliced
- 1 brown onion, finely diced (about 1 cup)
- 2 garlic cloves, minced
- 3 tbsp olive oil, divided
- 2 1/2 cups warm liquid (a combination of zucchini juices plus milk, heated)
- 2/3 cups parmesan cheese, grated
- 1/2 cup medium grain white rice, uncooked
- 2 tbsp all-purpose flour
- 2 tsp salt
- Black pepper, to taste
Instructions
- Prepare the zucchini: Rinse and thinly slice the zucchini. Place the slices in a colander, sprinkle with 1 teaspoon of salt, and let sit for about 15 minutes. This draws out excess moisture from the zucchini. Then, gently squeeze the zucchini slices to remove additional liquid and set aside the juices collected for use in the recipe.
- Sauté onion and garlic: In a medium pan, heat 1 tablespoon of olive oil over medium heat. Add the finely diced brown onion and minced garlic, cooking until softened and translucent, about 5 minutes. Remove from heat.
- Prepare the liquid base: Combine the reserved zucchini juices with warmed milk in a small saucepan. Heat gently until warm but not boiling. This mixture will be used to cook the rice and provide moisture for the dish.
- Assemble the zucchini mixture: In a large mixing bowl, whisk together the flour, salt, and black pepper. Add the grated parmesan cheese, the uncooked rice, sautéed onion and garlic, and 2 tablespoons of olive oil. Slowly add the warm zucchini juice and milk mixture to the dry ingredients, stirring until well combined.
- Layer the tian: Preheat your oven to 180°C (356°F). In a lightly oiled baking dish, arrange a layer of zucchini slices, then spread a portion of the rice and cheese mixture evenly over the zucchini. Repeat layering until all ingredients are used, finishing with a layer of zucchini on top. Drizzle a little olive oil over the top for a golden finish.
- Bake the Zucchini Tian: Place the baking dish in the preheated oven and bake for approximately 45 minutes, or until the top is golden brown and the rice is fully cooked and tender. Allow to rest for a few minutes before serving to let the flavors meld together.
Notes
- Use medium grain rice to ensure proper texture as it absorbs moisture well during baking.
- Make sure to gently squeeze the zucchini to remove excess liquid to prevent a soggy tian.
- Parmesan cheese adds a rich umami flavor, but you can substitute with Pecorino Romano if preferred.
- The warm liquid mix of zucchini juices and milk is essential to cook the rice evenly during baking.
- This dish pairs beautifully with a fresh green salad and crusty bread.
