Ingredients for Vegetable Tian
Here’s what you’ll need to prepare this colorful casserole:
- Zucchini (2 medium) – Choose firm zucchinis with smooth skin. They add a mild sweetness and moisture to the dish.
- Eggplant (1 medium) – Go for smaller to medium eggplants with shiny skin; they tend to be less bitter.
- Tomatoes (3–4 medium ripe) – Juicy, ripe tomatoes (Roma or heirloom work best).
- Onion (1 large, optional) – Thinly sliced onion adds extra depth of flavor.
- Garlic (3–4 cloves, minced) – Fresh garlic enhances the aromatic profile.
- Olive Oil (3–4 tbsp, extra virgin) – The key to richness and proper roasting.
- Fresh Thyme (2–3 sprigs) – Gives the dish a fragrant, earthy aroma.
- Salt & Black Pepper (to taste) – Essential for seasoning.
Optional additions:
- Grated Parmesan or Mozzarella – For a cheesy golden top.
- Fresh Basil or Oregano – Adds Italian-style flavor.
- Red Pepper Flakes – For a little heat.
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a baking dish with olive oil.
Step 2: Prepare the Vegetables
- Wash zucchini, eggplant, and tomatoes.
- Slice them into ¼-inch thick rounds (keep thickness consistent for even cooking).
- If eggplant is large or bitter, sprinkle slices with salt and let them rest for 15 minutes, then pat dry.
Step 3: Arrange the Layers
- Start with alternating slices of zucchini, eggplant, and tomato.
- Arrange them in a circular pattern (shingled style) or straight rows in your baking dish.
- Continue until all slices are neatly layered.
Step 4: Add Garlic and Seasoning
- Sprinkle minced garlic evenly over the vegetables.
- Season generously with salt and pepper.
- Drizzle olive oil evenly across the top.
- Scatter thyme leaves (or place sprigs on top).
Step 5: Bake
- Cover the dish with aluminum foil.
- Bake for 30 minutes covered, then remove foil and bake another 20 minutes uncovered, until vegetables are tender and lightly caramelized on the edges.
Step 6: Optional Cheese Topping
If using cheese, sprinkle grated Parmesan or Mozzarella during the last 10 minutes of baking.
Step 7: Serve
- Allow to cool slightly before serving.
- Drizzle with extra virgin olive oil or garnish with fresh herbs before plating.
Serving Suggestions
This Vegetable Tian pairs beautifully with a variety of sides and mains:
- Crusty Bread – Perfect to soak up the juices.
- Steamed Rice or Quinoa – Adds substance and balances the flavors.
- Mashed Potatoes – Comfort food pairing.
- Grilled Chicken, Fish, or Steak – If you want a protein-rich main.
- Fresh Green Salad – Light and refreshing contrast.
Make Ahead & Storage
- Make Ahead: Slice and prep vegetables a day before. Assemble the dish, cover tightly, and refrigerate up to 24 hours before baking.
- Storing Leftovers: Store cooled leftovers in an airtight container for up to 4 days in the fridge.
- Freezing: Wrap portions tightly and freeze for up to 3 months. Thaw overnight before reheating.
- Reheating: Warm in a 350°F oven for 20 minutes (covered with foil).
Tips & Tricks for the Best Vegetable Tian
- Uniform Slicing = Even Cooking – Use a mandoline for perfect slices.
- Don’t Overcrowd – Overlapping too tightly traps steam and prevents caramelization.
- Use Seasonal Vegetables – Peak-season zucchini, tomatoes, and eggplant give the best flavor.
- Add Cheese Wisely – Parmesan adds saltiness, mozzarella gives creaminess—choose based on taste.
- Pre-Cook Dense Veggies – Lightly sauté eggplant or carrots if using, so they don’t release too much water while baking.
Recipe Variations
- Cheesy Vegetable Tian – Add mozzarella, Gruyère, or Parmesan for extra richness.
- Vegan Tian – Skip cheese; use nutritional yeast for a cheesy flavor.
- Low-Carb/Keto Tian – Skip tomatoes, use zucchini, bell peppers, and mushrooms.
- Mediterranean Tian – Add olives, feta cheese, and oregano.
- Spicy Tian – Add sliced jalapeños or sprinkle red chili flakes.
