Instructions

Prepare the Zucchini

Slice zucchini thinly and lightly salt it. Let it sit for 10–15 minutes to release excess moisture, then pat dry. Grill or lightly sauté in olive oil until just tender and slightly golden. Set aside.

Make the Béchamel Sauce

In a saucepan, melt butter over medium heat. Add minced garlic and onion, cooking until soft and fragrant. Stir in flour and cook for 1–2 minutes to remove raw taste.

Gradually whisk in warm milk, stirring continuously to avoid lumps. Cook until the sauce thickens into a smooth, creamy consistency. Season with salt, black pepper, and nutmeg.

Assemble the Parmigiana

Preheat oven to 180°C (350°F). In a baking dish, start with a thin layer of béchamel sauce. Add a layer of zucchini, followed by mozzarella, Parmigiano-Reggiano, and optional ham or pancetta.

Repeat layers until ingredients are used, finishing with béchamel and a generous topping of cheese.

Bake

Bake for 35–40 minutes until golden, bubbling, and slightly crisp on top. Let it rest for 10 minutes before serving to help it set.

Tips

Slice zucchini evenly for consistent cooking and layering.

Salt zucchini beforehand to reduce excess moisture and prevent a watery dish.

Do not overcook zucchini before baking; it should remain slightly firm.

Whisk béchamel continuously to ensure a smooth, lump-free sauce.

Use warm milk when making béchamel for easier thickening.

Layer ingredients evenly to ensure balanced flavor in every bite.

Let the dish rest before cutting to allow clean slices.

Use freshly grated nutmeg for authentic béchamel flavor.

Avoid overly thick béchamel; it should remain pourable.

Use a mix of cheeses for deeper flavor and better melt.

Bake until the top is golden and slightly crisp for best texture.

Variations

Add spinach or sautéed mushrooms for extra vegetables.

Use smoked provola or scamorza for a deeper smoky flavor.

Replace ham with grilled chicken for a protein-rich version.

Add chili flakes for a light spicy kick.

Use ricotta between layers for a creamier texture.

Add sun-dried tomatoes for a sweet-tangy contrast.

Replace mozzarella with fontina or gouda for richer melt.

Use whole wheat flour in béchamel for a nuttier flavor.

Add pesto drizzle between layers for herbal freshness.

Make it vegetarian by skipping all meats.

Top with breadcrumbs for a crispier crust.
