Ingredients for Zucchini and Eggplant Gratin

For this simple yet flavorful baked zucchini eggplant gratin with herbs, you’ll need:

• Olive oil spray (for greasing the baking dish)
• 250g zucchini (about 2 medium), sliced lengthways into 5mm thick strips
• 370g eggplant (about 1 large), sliced lengthways into 5mm thick strips
• 1⅓ cups pasta sauce (store-bought or homemade marinara)
• 1 cup mozzarella cheese, grated
• ¼ cup grated Parmesan (optional, for extra flavor)
• ½ cup panko breadcrumbs (or gluten-free breadcrumbs for a gluten-free zucchini and eggplant gratin)
• 1 teaspoon dried Italian herbs (or 1 tablespoon fresh herbs like basil, thyme, and oregano)
• 2 cloves garlic, minced
• Salt and pepper to taste

Ingredient Notes and Substitutions

• For a zucchini eggplant gratin with marinara sauce variation, use a chunky homemade marinara instead of regular pasta sauce
• If making a gluten-free zucchini and eggplant gratin, substitute panko with gluten-free breadcrumbs or crushed almonds
• For a lighter version, use part-skim mozzarella or reduce the cheese by half
• Yellow squash works beautifully as a zucchini substitute if needed

How to Make Zucchini and Eggplant Gratin – Step by Step

Step 1: Prepare the Vegetables

1. Preheat your oven to 375°F (190°C) and spray a 9×13 inch casserole dish with olive oil.
2. Slice your zucchini and eggplant lengthways into approximately 5mm thick strips.
3. Optional but recommended: Place eggplant slices on paper towels and sprinkle lightly with salt. Let sit for 10 minutes to draw out moisture, then pat dry.

Step 2: Season the Vegetables

1. Arrange the zucchini and eggplant slices on a baking sheet.
2. Lightly spray them with olive oil and season with salt, pepper, and half of the minced garlic.
3. For an optional step that adds depth, quickly pre-roast the vegetables for 10 minutes until slightly softened.

Step 3: Assemble Your Savory Zucchini Eggplant Gratin in a Casserole Dish

1. Spread ¼ cup of pasta sauce on the bottom of your prepared casserole dish.
2. Create a layer using half of the zucchini and eggplant slices, slightly overlapping them.
3. Top with half of the remaining pasta sauce and sprinkle with half of the mozzarella.
4. Add a second layer with the remaining vegetables, followed by the remaining sauce.
5. In a small bowl, combine breadcrumbs, Parmesan cheese (if using), dried herbs, remaining garlic, and a light spray of olive oil.

Step 4: Bake to Perfection

1. Sprinkle the remaining mozzarella over the top of your gratin.
2. Top with the breadcrumb mixture, distributing evenly.
3. Bake uncovered for 25-30 minutes until the cheese is bubbly and the top is golden brown.
4. Allow to rest for 5-10 minutes before serving your beautiful Zucchini and Eggplant Gratin.

Pro Tips for Making the Best Zucchini and Eggplant Gratin

• Salt your eggplant first: This draws out moisture and bitterness, resulting in a better-textured final dish.
• Don’t skip the breadcrumbs: They provide crucial textural contrast to the soft vegetables and melted cheese.
• Layer strategically: Alternate vegetables for the most attractive presentation when sliced.
• Let it rest: A 5-10 minute rest after baking allows the Zucchini and Eggplant Gratin to set up properly for cleaner serving.
• Make it your own: Add a layer of sautéed onions and bell peppers or mix in some cooked ground meat for a heartier version.
