Cook the lasagna noodles according to package instructions until al dente. Drain and set aside on a flat surface to cool.
In a large mixing bowl, combine the ricotta cheese, half of the mozzarella cheese, Parmesan cheese, chopped spinach, egg, minced garlic, Italian seasoning, salt, and pepper. Mix well until all ingredients are thoroughly combined.
Take one lasagna noodle and spread a generous spoonful of the cheese and spinach mixture evenly along the top side. Roll the noodle tightly and place it seam-side down in a greased 9x13 inch baking dish. Repeat with the remaining noodles and filling.
Pour the marinara sauce evenly over the lasagna roll ups, ensuring they are well covered. Sprinkle the remaining mozzarella cheese on top.
Cover the dish with aluminum foil and bake for 25 minutes. Then, remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden brown.
Once baked, let the roll ups sit for about 5 minutes before serving. Garnish with fresh basil leaves.
Notes
Serve the roll ups on a plate drizzled with extra marinara sauce and topped with a sprinkle of fresh basil for a pop of color.
