Key Ingredients:

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

Zucchini: I prefer small to medium-sized ones for the sweetest flavor. It adds texture and holds up well when roasted. Zucchini is a keto-friendly vegetable powerhouse.

Yellow Squash: This adds beautiful color and a mild, sunny sweetness. It perfectly balances the more earthy flavors in the dish.

Tomatoes: Go for ripe, firm tomatoes to avoid excessive juiciness. They break down and create a lovely, natural sauce. This provides incredible depth of flavor.

Potatoes (Optional, as shown): These are classic in a Provencal tian, absorbing all the juices. However, if you are strictly keto, you must omit them or swap for something else.

Parmesan Cheese: I always recommend freshly grated cheese. This is for the best melting. It adds that perfect salty, savory bite on top.

Olive Oil: A good extra virgin olive oil is key. Because it helps roast the veggies perfectly and enhances their natural flavors.

Fresh Herbs: I love fresh thyme and oregano for this recipe. However, dried herbs also work. They provide that authentic Mediterranean flavor profile.

How to Make Vegetable Tian

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

1. Preheat your oven to 400°F (200°C).
2. Next, lightly grease an oval baking dish with a little olive oil.
3. Then, prepare all your vegetables. Slice the zucchini, yellow squash, tomatoes, and potatoes (if using) into even, 1/4-inch round slices.
4. Begin layering. Stand the vegetable slices vertically in the prepared dish. For example, alternate your slices—potato, tomato, zucchini, squash. Repeat this pattern until the entire dish is packed tightly.
5. After layering, drizzle the vegetables generously with olive oil. Season well with salt, pepper, and your fresh herbs.
6. Next, cover the dish with foil. This helps steam the vegetables until they are very tender.
7. Bake for 30 minutes in your preheated oven. Then, remove the foil.
8. Sprinkle the grated parmesan and mozzarella (if using) cheese evenly over the top.
9. Return the dish to the oven, uncovered. Continue to bake for another 15–20 minutes.
10. Finally, switch the oven to broil for 2–3 minutes. This ensures the cheese is perfectly melted, bubbly, and golden. Keep a close eye on it so it doesn’t burn!
11. Remove from the oven and let it rest for 5–10 minutes. This allows the juices to settle slightly before serving.

Pro Tip: For extra depth of flavor, roast some garlic cloves whole and tuck them in between the vegetable layers.

Common Mistakes to Avoid:

• Slicing Unevenly: This leads to some veggies being undercooked while others are mushy. Use a mandoline or a sharp knife for consistent slices.
• Overcooking: Keep an eye on the timing so the vegetables retain some texture and don’t turn into a puree.
• Skipping the Foil: Baking covered at first ensures tenderness. Removing it later browns the cheese.
• Ignoring Seasoning: Vegetables require substantial salt and pepper to really pop, so don’t be shy!

Required Equipment:

• 9×13-inch Baking Dish (or oval casserole dish): This is essential for layering the vegetables neatly and baking them evenly.
• Sharp Knife (or Mandoline): Ensures you can get uniform slices, which is key for even cooking.

Caleb’s Recipe Tips

• Choose Smaller Vegetables: Select zucchini and squash with similar diameters to make the layering process simpler and visually appealing.
• Add Extra Cheese: For a true comfort food experience, add more cheese; a mozzarella-parmesan blend is particularly delicious.
• Use Dry Herbs: If you don’t have fresh herbs, use dried thyme or oregano; however, reduce the quantity as dried herbs are more potent.
• Tuck in Garlic: Slice a garlic clove and nestle pieces in between the layers for subtle, delicious flavor in every bite.
• Let It Rest: This step is crucial. Resting allows the vegetables to firm up slightly and the natural juices to redistribute, making the dish easier to serve.

Storage Instructions

This Vegetable Tian stores beautifully in the refrigerator. Transfer any leftovers to an airtight container. It will keep well for up to 3 days. Instead of freezing, which changes the texture significantly, I recommend enjoying it fresh.

When ready to eat, you can reheat it efficiently. Simply place a serving in a microwave-safe dish and heat it gently until warmed through. Alternatively, warm it in the oven at 350°F (175°C) until bubbly.

Ingredients

Scale

1/2x 1x 2x 3x

• 2 large zucchini, sliced into rounds (about 1/4 inch thick)
• 2 large yellow squash, sliced into rounds (about 1/4 inch thick)
• 4 large, firm Roma tomatoes, sliced into rounds (about 1/4 inch thick)
• 1 large Russet potato (optional, only if not seeking a low-carb recipe)
• 1 large onion, thinly sliced (optional base layer, adds lots of flavor)
• ¹⁄₄ cup extra virgin olive oil
• 1 tbsp fresh thyme leaves (or 1 tsp dried thyme)
• ¹⁄₂ tsp dried oregano
• ³⁄₄ cup freshly grated Parmesan cheese
• ¹⁄₂ cup shredded mozzarella cheese (optional for extra meltiness)
• Salt and black pepper, to taste

Instructions

1. First, preheat your oven to 400°F (200°C) and grease a 9x13 baking dish with olive oil.
2. Then, prepare all the vegetables by slicing them to a consistent thickness; this step ensures they will cook evenly.
3. Next, layer the onion slices (if using) evenly on the bottom of the baking dish to form a flavor base.
4. Then, begin tightly layering the sliced vegetables (zucchini, squash, tomatoes, and potatoes if using) in the dish, standing them vertically and alternating in a pattern.
5. After that, drizzle the olive oil generously over the vegetables and season thoroughly with salt, pepper, thyme, and oregano.
6. Cover the dish tightly with aluminum foil and bake in the preheated oven for 30 minutes.
7. Next, carefully remove the foil and sprinkle both the grated parmesan and shredded mozzarella cheese (if using) evenly over the top.
8. Then, return the dish to the oven, uncovered, and continue to bake for another 15–20 minutes.
9. Finally, for that perfect golden crust, turn the oven to broil for 2–3 minutes; monitor it closely to prevent burning.
10. Remove the tian from the oven and allow it to rest for at least 10 minutes before serving.

Note

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven until warmed through. This tian does not freeze well, as the texture of the vegetables degrades significantly upon thawing. For an extra flavor boost, try brushing the vegetables with pesto before baking.
