Ingredients

Instructions

Preparation Phase

Begin by preheating your oven to 400°F (200°C). This ensures that by the time you finish layering the vegetables, the oven will be at the perfect temperature for baking. While the oven warms up, prepare your vegetables. Wash the zucchinis and tomatoes thoroughly under cold running water to remove any dirt or residues. Pat them dry with a clean kitchen towel or paper towels to prevent excess moisture from affecting the layering process or the final texture of the gratin.

Vegetable Slicing

Using a sharp chef’s knife or a mandoline slicer for uniformity, slice the zucchini into thin, even rounds approximately 1/8 inch thick. Consistent thickness ensures even cooking and a beautiful layered appearance. Similarly, slice the tomatoes into rounds of similar thickness. Uniform slices prevent some parts from overcooking while others remain underdone and promote a harmonious texture throughout the dish.

Layering the Gratin

Choose an 8-inch square baking dish or a similar ovenproof vessel that provides enough space for layering without overcrowding. Lightly grease the dish with a small amount of olive oil or non-stick spray to facilitate easy removal and prevent sticking. Start by placing half of the zucchini slices in a neat, overlapping layer across the bottom of the dish. Ensure the slices are laid flat and slightly overlapping, resembling the tiles on a roof. Then, add a layer of half of the tomato slices on top of the zucchini, arranging them similarly in overlapping circles.

Sprinkle 1/4 cup of freshly grated Parmesan cheese evenly over the tomato layer. This cheese adds a savory umami flavor and creates a slightly crispy, golden crust when baked. Repeat the layering process: add the remaining zucchini slices followed by the remaining tomato slices, maintaining the same overlapping pattern for aesthetic appeal and even cooking.

Seasoning and Flavor Enhancement

In a small bowl, combine the minced garlic, dried thyme, salt, and pepper. Distribute this seasoning mixture evenly over the layered vegetables. The garlic will provide a pungent, aromatic base note, while thyme adds a subtle earthy flavor that complements the vegetables. Seasoning directly over the vegetables ensures each bite is flavorful and well-rounded.

Olive Oil Drizzle and Final Cheese Topping

Drizzle the 2 tablespoons of olive oil evenly across the top of the layered vegetables. The oil helps in roasting the vegetables to tender perfection and enhances the richness of the dish. Finish by sprinkling the remaining 1/2 cup of Parmesan cheese over the entire gratin, creating a crust that will turn beautifully golden and slightly crispy during baking.

Baking and Finishing

Place the prepared dish on the middle rack of the preheated oven. Bake for about 20-25 minutes, or until the vegetables are tender when pierced with a fork and the cheese topping is bubbly and golden brown. Keep an eye on the gratin during the last few minutes to prevent burning. If the cheese is perfectly melted and golden but the vegetables need a bit more time, you can extend baking by a few minutes.

Once done, carefully remove the gratin from the oven. Let it rest for 5 minutes to allow the flavors to settle and the baking juices to redistribute. Use a slotted spoon or a large spatula to serve, allowing excess liquid to drain slightly to prevent sogginess and ensure a crisp top layer.

Preparation Tips

• Slice Uniformly: For even cooking, slices should be as uniform as possible. Use a mandoline for perfect consistency.
• Pre-salt the vegetables: Optional, but lightly salting zucchini and tomatoes before layering can draw out excess moisture, preventing a soggy gratin.
• Cheese substitution: For a dairy-free version, substitute Parmesan with nutritional yeast or vegan cheese options.
• Layer neatness: Overlapping slices in an organized manner not only makes the dish look appealing but also promotes even baking.
• Adjust seasoning: Feel free to add fresh herbs like basil or oregano for additional flavor.

Nutritional Information

Tips and Tricks

• Use fresh ingredients: The flavor of ripe tomatoes and garden-fresh zucchinis elevates this dish exponentially.
• Enhance cheese flavor: Mix Parmesan with a little grated Pecorino Romano for a sharper flavor.
• Layering aesthetics: Arrange slices in concentric circles or zigzag patterns for a more artistic presentation.
• Vegetable prep: For a more intense flavor, roast the zucchini and tomatoes separately before layering.
• Make ahead: Assemble the gratin a few hours before baking; keep refrigerated until ready to bake for enhanced flavors.

Add-ons

• Chopped fresh basil or parsley sprinkled on top before serving
• Crushed red pepper flakes for a spicy kick
• Additional herbs such as oregano, rosemary, or marjoram for varied flavor profiles
• Thin slices of mozzarella or other melting cheese for extra creaminess

Side Dishes

• Grilled chicken or fish to make it a complete meal
• Crusty artisan bread or garlic bread
• Mixed green salad with vinaigrette
• Roasted potatoes or a vegetable medley

Improvements

• Layer with thin slices of eggplant or bell peppers for added texture and flavor
• Use heirloom tomatoes for a more colorful and flavorful presentation
• Incorporate a splash of balsamic vinegar or lemon juice before baking for a tangy depth
• Add a breadcrumb topping mixed with herbs and olive oil for crunch

Save and Store

Leftover gratin can be cooled to room temperature and stored in an airtight container in the refrigerator for up to 3 days. To reheat, place slices in a preheated oven at 350°F (175°C) for about 10-15 minutes until warmed through and cheese is bubbly. For best results, avoid microwaving as it can make the texture soggy and diminish flavor integrity. If preparing in advance, assemble the gratin without baking and refrigerate, then bake fresh when needed.
