Preheat oven to 375°F (190°C).
In a mixing bowl, combine ricotta, Parmesan, eggs, salt, and pepper.
In a skillet, heat olive oil over medium heat. Add onion and garlic, sauté until translucent.
Add spinach to the skillet and cook until wilted. Remove from heat and let cool.
Spread each lasagna noodle with a layer of the ricotta mixture, followed by a layer of spinach.
Carefully roll each noodle up tightly and place in a baking dish standing on end.
Pour marinara sauce over the noodles and top with shredded mozzarella.
Cover with foil and bake for 25 minutes. Remove foil and bake for another 10 minutes or until cheese is bubbly and golden.
