Ingredients
For the zucchini
- 4 medium zucchini (about 2 lb), sliced 1/4-inch thick
- 2 tablespoons kosher salt, for drawing out moisture
- 1 cup all-purpose flour
- 2 large eggs, beaten with 2 tablespoons water
- 1 1/2 cups plain fine breadcrumbs
- 1/2 cup grated Parmigiano-Reggiano, mixed into the breadcrumbs
- 1/2 cup vegetable oil, for shallow frying
For the tomato sauce
- 3 cups San Marzano tomatoes, hand-crushed
- 3 tablespoons extra-virgin olive oil
- 3 cloves garlic, thinly sliced
- 1/2 teaspoon kosher salt
- 8 fresh basil leaves, torn
- Pinch of sugar, if needed
For assembly
- 8 oz fresh mozzarella, torn into bite-size pieces
- 3/4 cup grated Parmigiano-Reggiano
- 10 fresh basil leaves
- 1 tablespoon extra-virgin olive oil, for drizzling
Directions
- Arrange the zucchini slices on a wire rack set over a sheet pan, sprinkle both sides with the kosher salt, and let rest for 15 minutes to draw out excess moisture. Pat completely dry with paper towels.
- Meanwhile, make the sauce: warm the olive oil in a small saucepan over medium heat, add the garlic and cook until just golden, then add the crushed tomatoes, salt, and a pinch of sugar. Simmer gently for 12 minutes, stir in the torn basil, and remove from heat.
- Set up a breading station with three shallow bowls: flour, beaten eggs, and the breadcrumb-Parmigiano mixture. Dredge each zucchini slice in flour, dip in egg, then coat thoroughly in the seasoned breadcrumbs, pressing gently to adhere.
- Heat the vegetable oil in a large skillet over medium-high heat until shimmering. Fry the breaded zucchini in batches for about 2 minutes per side, until deep golden, then transfer to a paper-towel-lined plate. You should have 18 to 20 slices.
- Preheat the oven to 400°F (200°C). Spread a thin layer of sauce in the bottom of a 9×13-inch baking dish. Arrange a single layer of fried zucchini over the sauce, top with one-third of the mozzarella, one-third of the remaining Parmigiano, a few basil leaves, and a ladle of sauce.
- Repeat the layering twice more, finishing with sauce, the last of the Parmigiano, a final drizzle of olive oil, and a few whole basil leaves on top.
- Bake uncovered for 22 to 25 minutes, until the cheese is melted, the sauce is bubbling at the edges, and the top is golden brown.
- Let the parmigiana rest for at least 10 minutes before serving so the layers set; serve warm with crusty bread or a simple green salad.
Cook’s Notes
- Salting and resting the zucchini is essential; skipping this step will make the casserole watery.
- For a lighter version, skip the frying and brush the breaded slices with olive oil, then bake at 425°F for 20 minutes until crisp before layering.
- Use whole-milk fresh mozzarella packed in water for the creamiest melt; pat it dry with paper towels first to avoid excess moisture.
- Letting the finished dish rest 10 to 15 minutes before slicing is key to clean, sturdy layers that hold their shape on the plate.
- Leftovers keep well refrigerated for up to 3 days and reheat beautifully in a 350°F oven for 12 minutes.
