Preheat oven to 200°C (400°F). Using a Y-peeler, shave zucchini into wide ribbons. Generously salt the ribbons on paper towel-lined baking sheets, layering with additional paper towels. Let drain for 15 to 45 minutes to extract moisture.

Heat olive oil in a small pot over medium heat. Sauté onion and garlic until translucent, about 5 minutes. Add marinara sauce and simmer over medium-low heat, stirring occasionally, until thickened and excess liquid evaporates, approximately 12 to 15 minutes.
03 -
In a medium bowl, mix eggs, mozzarella, ricotta, garlic powder, Italian seasoning, and 1 cup (about 85 g) of Parmesan. Season with freshly ground black pepper to taste.
04 -
Spread a thin layer of thickened marinara in a 33 x 23 cm (13 x 9 inch) baking dish. Layer two zucchini ribbons over the sauce, then one-third of the cheese mixture, followed by one-third of the remaining marinara sauce. Repeat this layering process two more times.
05 -
Arrange zucchini ribbons side by side diagonally over the final marinara layer. Lift the bottom half of every other ribbon and lay another zucchini ribbon across diagonally to form a lattice pattern. Season with black pepper and sprinkle the remaining 1/2 cup (about 43 g) Parmesan evenly over the top.
06 -
Cover the dish with foil and bake in the preheated oven for 30 minutes until the cheese is melted and zucchini tender.
07 -
Remove foil and continue baking for 15 minutes or until the top is golden brown and crisp at the edges.
08 -
Allow the dish to cool for at least 10 minutes before slicing to set the layers.
