Preheat the oven to 350 degrees.
Slice the zucchini into strips with a vegetable peeler and place on paper towels to allow moisture to be absorbed.
Mix ricotta, Parmesan, mozzarella, eggs, parsley, garlic, salt and pepper into a large bowl.
Pour half the marinara sauce in the bottom of a 9x13 baking dish.
Spoon half a tablespoon of the cheese mixture onto a piece of zucchini and roll.
Place the zucchini bundles standing up into the marinara sauce.
Pour the remaining sauce around and in between the zucchini bundles, cover and bake for 20-25 minutes.
Uncover and bake for an additional 10 minutes.
