Instructions
Step 1: Prepare the Vegetables
Wash all vegetables thoroughly. Peel the potatoes and onions.
Slice the potatoes, zucchini, yellow squash, tomatoes, onion, and optional beetroot into thin rounds, about â…› inch thick. Thin, even slices help the vegetables cook evenly and create the classic layered appearance.
Step 2: Prepare the Garlic Herb Oil
In a bowl, combine the olive oil, melted butter, minced garlic, Italian seasoning, thyme, rosemary, oregano, paprika, salt, and black pepper.
Mix well until the seasoning is evenly blended into the oil and butter.
Step 3: Prepare the Baking Dish
Lightly grease the baking dish with olive oil.
Spread 2 tablespoons of the garlic herb mixture across the bottom of the dish. This adds flavor to the base and helps prevent sticking.
Step 4: Arrange the Vegetables
Arrange the vegetable slices vertically in alternating layers.
A simple pattern is potato, tomato, zucchini, onion, and beetroot. Repeat the pattern until the baking dish is completely filled.
Keep the slices tightly packed so the tian holds its shape while baking.
Step 5: Add the Seasoning
Use a pastry brush to generously coat the tops of the vegetables with the remaining garlic herb oil.
Make sure every slice is lightly coated. Sprinkle Parmesan cheese, crumbled feta, and fresh parsley over the top.
Step 6: Bake
Cover the baking dish with aluminum foil.
Bake at 375°F (190°C) for 45 minutes.
Step 7: Remove the Foil
Carefully remove the foil.
Bake for another 20–25 minutes, or until the potatoes are tender, the cheese is golden, the vegetable edges are caramelized, and the tomatoes are soft.
Step 8: Garnish and Serve
Top the baked vegetable tian with fresh dill, extra feta, and chopped parsley.
Serve immediately while hot.
Expert Tips
For even cooking, slice the vegetables as uniformly as possible. A mandoline slicer is helpful because it creates thin, consistent rounds.
Do not skip the fresh garlic. It gives the dish a deeper flavor than garlic powder and blends beautifully with the herbs, oil, and butter.
Choose firm vegetables, especially tomatoes and zucchini. Overly ripe vegetables can release too much moisture while baking.
Pack the vegetables tightly in the dish. This helps the tian keep its layered structure and gives the finished casserole its signature look.
For extra golden cheese and crisp edges, place the dish under the broiler for 2–3 minutes at the end of baking. Watch closely so the top does not burn.
Recipe Variations
For a Mediterranean version, add Kalamata olives, crumbled feta, and fresh basil.
For a cheesier version, use a blend of mozzarella, Parmesan, Gruyère, and cheddar.
For a vegan version, replace the butter with additional olive oil and use vegan cheese, or omit the cheese entirely.
For a protein version, add cooked chicken, turkey slices, ground beef, or Italian sausage between the vegetable layers.

Frequently Asked Questions
Can I make this recipe ahead of time?
Yes. Assemble the vegetables up to one day in advance, cover, and refrigerate. Bake just before serving for the best texture and flavor.
Do I have to peel the potatoes?
No. Thin-skinned potatoes such as Yukon Gold can be left unpeeled after a good scrub. Russet potatoes are often peeled for a smoother texture.
What cheese works best?
Parmesan adds savory, nutty flavor and helps create a crisp topping. Feta adds a creamy, tangy finish. Gruyère or mozzarella can also be used for a richer, meltier result.
Why are my vegetables watery?
Tomatoes and zucchini naturally release moisture during baking. To reduce excess liquid, use firm vegetables, slice evenly, avoid overcrowding, and bake uncovered during the final 20–25 minutes.
Can I make this vegan?
Yes. Replace the butter with additional olive oil and use your favorite plant-based cheese, or omit the cheese for a lighter version.
