Prepare the zucchini: Cut the zucchini into even wedges. Sprinkle with 1 teaspoon salt and let them rest for a few minutes, until a little moisture appears on the surface.
Make the coating: In a shallow bowl, combine the breadcrumbs, cornmeal, paprika, garlic powder, 1 teaspoon salt, black pepper, and coriander.
Coat the zucchini: Roll each zucchini wedge in the seasoned breadcrumb mixture, pressing lightly so the coating sticks to the surface.
Arrange on the pan: Place the coated zucchini in a single layer on a parchment-lined baking sheet.
Bake the zucchini: Bake at 400°F (200°C) for 25 minutes, until the zucchini is tender and the coating is lightly golden.
Add the mozzarella: Remove the baking sheet from the oven and sprinkle the shredded mozzarella evenly over the zucchini.
Finish baking: Return the pan to the oven and bake for another 5 minutes, until the mozzarella is melted and lightly golden on top.
Serve: Serve warm, while the cheese is melted and the coating has its best texture.
