How to Make Savory Baked Mediterranean Vegetable Casserole Recipe
Step 1: Preheat and Prepare
Start by heating your oven to 400°F (200°C). This ensures it’s at the perfect temperature to roast the vegetables evenly, bringing out their natural sweetness and creating that irresistible golden finish.
Step 2: Combine Your Vegetables
In a large mixing bowl, toss together sliced zucchinis, eggplants, chopped red and yellow bell peppers, sliced red onion, and halved cherry tomatoes. Getting all these vibrant veggies combined upfront makes seasoning and tossing much easier.
Step 3: Spice and Oil
Add the minced garlic to the bowl, then drizzle the olive oil over the vegetables. Sprinkle dried oregano, basil, plus salt and pepper to taste. These ingredients will infuse the whole dish with those iconic Mediterranean flavors you crave.
Step 4: Toss to Coat
Give everything a good toss so each vegetable slice is coated evenly with the olive oil and herbs. This step is key to ensuring a consistent roast and burst of flavor in every bite.
Step 5: Transfer and Spread
Move the coated vegetables to a large baking dish, spreading them out in an even layer. Taking care to avoid overcrowding helps the vegetables caramelize beautifully while roasting.
Step 6: Bake Until Tender
Pop the dish into your preheated oven for 35 to 40 minutes. At this point, the vegetables will soften and develop lovely roasted notes — smoky, sweet, and irresistible.
Step 7: Add Feta and Olives
After baking, remove the casserole from the oven and sprinkle the crumbled feta cheese and sliced kalamata olives evenly on top. These add creamy richness and bursts of salty flavor that elevate the dish.
Step 8: Melt the Feta
Return the dish to the oven for another 5 to 7 minutes so the feta softens and blends with the roasted veggies, creating a luscious, melt-in-your-mouth texture.
Step 9: Finish with Balsamic
Take the casserole out and drizzle the balsamic vinegar all over. This adds a perfect sweet and tangy lift that brightens every bite.
Step 10: Garnish and Serve
Sprinkle chopped fresh parsley and grated Parmesan cheese on top just before serving. These finishing touches add freshness and a savory depth, making your casserole visually stunning and even more delicious.
How to Serve Savory Baked Mediterranean Vegetable Casserole Recipe

Garnishes
Fresh parsley and a generous sprinkle of Parmesan bring a pop of color and a burst of flavor that complements the warm, roasted veggies perfectly. For an extra touch, add a few more kalamata olives or a drizzle of extra virgin olive oil.
Side Dishes
This casserole makes a fantastic main or side. Pair it with crusty bread or garlic pita to soak up all the juices. It also pairs beautifully with grilled chicken, fish, or a light couscous salad for a wholesome Mediterranean-inspired meal.
Creative Ways to Present
Try serving the casserole in individual ramekins for a charming presentation. Alternatively, layer the veggies and cheeses in a clear glass baking dish so everyone can admire the colorful layers before digging in. This dish also makes a great filling for savory crepes or wraps.
Make Ahead and Storage
Storing Leftovers
Place any leftovers in an airtight container and refrigerate for up to 3 days. The flavors actually deepen over time, making it even more delicious the next day!
Freezing
You can freeze the casserole, too. Just let it cool completely, then transfer to a freezer-safe dish or bag. It will keep well for up to 2 months, letting you enjoy this Mediterranean delight whenever you want.
Reheating
To reheat, thaw overnight in the fridge if frozen, then warm in a 350°F (175°C) oven until heated through and bubbly. This helps maintain the texture and flavor far better than the microwave.
FAQs
Can I use other vegetables in this casserole?
Absolutely! Feel free to add or swap in veggies like mushrooms, carrots, or spinach. The beauty of this Savory Baked Mediterranean Vegetable Casserole Recipe is its flexibility to use whatever fresh ingredients you love or have on hand.
Is this recipe suitable for vegans?
To make this casserole vegan, simply omit the feta and Parmesan cheeses or substitute them with plant-based alternatives. The dish will still be wonderfully flavorful and satisfying.
Can I prepare this recipe ahead of time?
Yes, you can assemble the vegetables and seasonings a few hours ahead and refrigerate them until you’re ready to bake. However, it’s best to add the cheese toppings right before the final baking step for optimal texture and flavor.
What type of feta cheese works best?
Try using a good quality, crumbly feta made from sheep or goat milk for maximum flavor. Avoid overly brined or watery types, as they can make the casserole soggy.
Can I use fresh herbs instead of dried oregano and basil?
Yes, fresh herbs bring a lovely brightness when available. Use about 1 tablespoon each of chopped fresh oregano and basil instead of dried, adding them with the olive oil before tossing.
