Preheat oven to 400 F, option to line 2 baking sheets with parchment paper for easy clean up.
Use a sharp knife to slice the zucchini into long strips. Place zucchini in a single layer on prepared baking sheets and spray with cooking spray. Bake in preheated oven until soft, about 10-12 minutes.
Combine ricotta, eggs, 1/4 cup of parmesan, half of the mozzarella, basil, garlic, dried oregano, salt, and black pepper, in a large bowl until well incorporated.
Pour half the marinara sauce in a 12" baking dish.
Lay zucchini slices on a flat surface. Spread the cheese combo onto each zucchini strip. Roll into a spiral, and place them over the marinara, placing the side by side so they support each other as they bake.
Once you're done rolling, cover the roll ups with remaining sauce, followed by the mozzarella and parmesan. If your dish is looking really full, place it on a rimmed baking sheet before transferring to the oven.
Bake in preheated oven for 18 minutes, and enjoy!
