Mediterranean Baked Zucchini with Mozzarella, Cherry Tomatoes & Garlic Herbs

There are some recipes that prove simple ingredients can create the most memorable meals, and this baked zucchini casserole is one of them. Honestly, I started making this recipe during the summer when my garden seemed to produce zucchini faster than I could use it. After experimenting with different combinations, I discovered that layering fresh zucchini with mozzarella, cherry tomatoes, garlic, olive oil, and Mediterranean herbs creates something incredibly comforting.

I usually serve this alongside grilled chicken or fish, but it’s just as satisfying on its own with a slice of warm crusty bread. The zucchini becomes perfectly tender, the tomatoes burst with sweetness, and the mozzarella melts into a golden, bubbly topping that’s impossible to resist.

If you’re looking for a healthy Mediterranean-inspired recipe that’s easy enough for busy weeknights but impressive enough for guests, this one deserves a spot on your menu.

Ingredients

For the Zucchini

  • 3 medium zucchini, sliced into ½-inch rounds
  • 2 tablespoons extra virgin olive oil
  • 4 cloves garlic, minced
  • 1 teaspoon Italian seasoning
  • 1 teaspoon dried oregano
  • ½ teaspoon dried basil
  • ½ teaspoon crushed red pepper flakes (optional)
  • Salt and freshly ground black pepper, to taste

For the Topping

  • 1½ cups shredded mozzarella cheese
  • 1 cup cherry tomatoes, halved
  • ¼ cup grated Parmesan cheese
  • 2 tablespoons chopped fresh parsley
  • 1 tablespoon chopped fresh basil
  • 1 tablespoon olive oil
  • Extra black pepper, for garnish

Kitchen Equipment

  • 9×13-inch baking dish
  • Mixing bowl
  • Sharp knife
  • Cutting board
  • Measuring spoons

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C).

Lightly grease a baking dish with olive oil.

Step 2: Season the Zucchini

In a large bowl, combine:

  • Zucchini slices
  • Olive oil
  • Garlic
  • Italian seasoning
  • Oregano
  • Basil
  • Red pepper flakes
  • Salt
  • Black pepper

Toss everything together until every zucchini slice is evenly coated.

Step 3: Arrange in the Baking Dish

Lay the zucchini slices in slightly overlapping layers inside the prepared baking dish.

Scatter the halved cherry tomatoes evenly over the zucchini.

Step 4: Add the Cheese

Sprinkle the shredded mozzarella evenly over the vegetables.

Top with grated Parmesan for an extra golden finish.

Finish with a drizzle of olive oil.

Step 5: Bake

Bake uncovered for 25–30 minutes, or until:

  • The zucchini is tender
  • The tomatoes have softened
  • The cheese is melted and bubbly

For a beautifully browned top, switch the oven to broil for the last 2–3 minutes, watching carefully to prevent burning.

Step 6: Garnish and Serve

Remove from the oven and let the casserole rest for 5 minutes.

Sprinkle with fresh parsley, chopped basil, and a little freshly cracked black pepper before serving.

Cooking Tips

I usually sprinkle a little salt over the zucchini slices and let them sit for about 15 minutes before cooking. This draws out excess moisture and helps keep the casserole from becoming watery.

Use freshly grated mozzarella whenever possible—it melts much better than pre-shredded cheese.

Fresh herbs add wonderful flavor, but dried herbs work perfectly if that’s what you have on hand.

If you like extra garlic, don’t be afraid to add another clove or two. Honestly, garlic is one of my favorite parts of this dish.

For a crispier topping, add a few tablespoons of seasoned breadcrumbs before baking.
