Ingredients:

For the Zucchini and Tomato Layer:

• 4 zucchini, sliced: Zucchini brings a mild, slightly sweet flavor and a tender texture, perfect for layering in this dish.
• 4 tomatoes, sliced: The acidity and juiciness of fresh tomatoes balance the richness of the cheese and other ingredients.
• 1 liter water: Used to blanch the zucchini and tomatoes, ensuring they’re tender but not overcooked.
• Salt, to taste: Enhances the natural flavors of the vegetables.
• Olive oil, for drizzling: Adds a smooth, rich flavor and helps the vegetables caramelize during baking.
• Fresh basil leaves, for garnish: Adds a fragrant and fresh finish to the dish, enhancing the flavor of the tomatoes and cheese.

For the Spinach and Cheese Filling:

• 150g spinach, chopped: Spinach adds a nutritious, earthy depth to the dish. It wilts beautifully, combining perfectly with the cheese.
• 100g cheese, grated (use any melty cheese like cheddar or gouda): This adds a creamy, rich texture that melds with the spinach, creating a luscious layer.
• 1 clove garlic, minced: Provides a subtle yet essential flavor that permeates the spinach and cheese mixture.
• Provençal herbs, to taste (or a mix of thyme, rosemary, and oregano): These herbs add a touch of Mediterranean flavor, bringing out the best in the zucchini and tomatoes.
• 200g mozzarella cheese, cubed: Melty mozzarella adds a stretchy, gooey element that makes each bite utterly satisfying.

For the Marinara Sauce:

• 1 onion, chopped: Adds a sweet and savory base to the sauce, providing depth of flavor.
• 3 cloves garlic, chopped: Garlic is essential for a robust, aromatic sauce that complements the sweetness of the tomatoes.
• 1 red pepper, chopped: Adds a slight sweetness and a bit of crunch to the sauce.
• 200g cherry tomatoes, halved: These add a burst of fresh tomato flavor and a lovely texture to the sauce.
• Vegetable oil, for sautéing: Helps soften the vegetables and bring out their flavors.
• 3 tablespoons tomato paste: Concentrated tomato flavor that thickens the sauce and gives it a rich, savory taste.
• Salt, pepper, and paprika, to taste: Seasonings that elevate the sauce, adding warmth and a hint of spice.

For Topping:

• 40g Parmesan cheese, grated: Parmesan adds a salty, nutty finish that crisps up beautifully under the broiler.

Instructions:

1. Prepare the Zucchini and Tomato Layer:
   • Blanching the Vegetables: Bring 1 liter of water to a boil with a pinch of salt. Add the zucchini slices and cook for 3-4 minutes until just tender. Be careful not to overcook them—they should be soft yet firm enough to hold their shape. Remove the zucchini with a slotted spoon and set them aside. In the same pot, blanch the tomato slices for about 2 minutes. This process helps remove excess moisture from the vegetables, preventing the dish from becoming too watery.
   • Drizzle with Olive Oil: Once blanched, place the zucchini and tomato slices on a tray and drizzle with olive oil. This will help them caramelize and develop a rich, roasted flavor during baking.
2. Make the Spinach and Cheese Filling:
   • Sauté the Garlic: Heat a drizzle of olive oil in a pan over medium heat. Add the minced garlic and sauté until fragrant—about 30 seconds to 1 minute. The garlic should turn golden but not brown, as this would make it bitter.
   • Cook the Spinach: Add the chopped spinach to the pan and cook until wilted, stirring occasionally. Spinach cooks down significantly, so don’t be alarmed by the initial volume. Season with Provençal herbs, salt, and pepper to taste. The herbs add a delightful aromatic quality that pairs well with the cheese.
   • Combine with Cheese: Remove the spinach from heat and immediately stir in the grated cheese. The residual heat will melt the cheese, creating a creamy, cohesive mixture that’s easy to spread.
3. Prepare the Marinara Sauce:
   • Sauté the Vegetables: In a saucepan, heat some vegetable oil over medium heat. Add the chopped onion and sauté until soft and translucent—about 5 minutes. The onion should be tender but not browned.
   • Add the Garlic and Red Pepper: Stir in the chopped garlic and red pepper, cooking for another 2-3 minutes until the vegetables are softened.
   • Add Cherry Tomatoes and Tomato Paste: Stir in the halved cherry tomatoes and tomato paste. The paste adds richness, while the cherry tomatoes provide bursts of fresh flavor. Cook for about 10 minutes until the sauce thickens slightly. Season with salt, pepper, and paprika to taste.
4. Assemble the Dish:
   • Layering: Preheat your oven to 180°C (350°F). In a large baking dish, start with a layer of zucchini slices, overlapping them slightly to cover the bottom of the dish. Follow with a layer of tomato slices. Next, spread a generous layer of the spinach and cheese mixture over the tomatoes. Sprinkle some cubed mozzarella on top for added creaminess. Repeat these layers until all ingredients are used, finishing with a layer of marinara sauce.
   • Top with Parmesan: Sprinkle the grated Parmesan cheese over the top. This will melt and create a crispy, golden crust during baking.
5. Bake:
   • Baking Time: Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly, and the top is golden brown. For an extra-crispy top, you can place the dish under the broiler for the last 2-3 minutes of cooking, keeping a close eye on it to prevent burning.
6. Serve:
   • Final Touches: Before serving, garnish with fresh basil leaves and a light drizzle of olive oil. The basil adds a fragrant, fresh flavor that complements the richness of the dish.
   • Serving Suggestions: This dish pairs wonderfully with a simple green salad and crusty bread. The bread is perfect for mopping up any extra sauce on your plate.

Tips and Tricks:

• Cheese Variations: Feel free to experiment with different types of cheese. Feta adds a tangy flavor, while ricotta can make the dish even creamier. For a stronger taste, try using a sharp cheddar or a blue cheese.
• Herb Substitutions: If you don’t have Provençal herbs, a mix of Italian seasoning or even fresh thyme and rosemary works well.
• Advance Preparation: You can assemble this dish up to a day ahead and store it in the refrigerator. Just bake it when you’re ready to serve.
• Leftovers and Freezing: Leftovers can be stored in the refrigerator for up to 3 days. This dish also freezes well—just cool it completely before transferring it to an airtight container. Reheat in the oven until heated through.
