Preheat oven to 375 degrees Fahrenheit (190 degrees Celsius).
In a medium bowl, combine ricotta cheese, beaten egg, 1 cup of mozzarella cheese, 1/4 cup of Parmesan cheese, Italian seasoning, salt, and pepper.
Lay the cooked lasagna noodles flat on a clean surface or parchment paper.
Spread approximately 3 tablespoons of the ricotta mixture evenly over each noodle.
Place 2 mini meatballs at one end of each noodle and roll the noodle tightly around the meatballs.
Spread 1 cup of marinara sauce across the bottom of a 9x13 inch baking dish.
Arrange the rolls in the baking dish with the seam-side facing down.
Pour the remaining marinara sauce over the rolls and sprinkle with the remaining mozzarella and Parmesan cheese.
Cover the dish with aluminum foil and bake for 30 minutes.
Remove the foil and bake for an additional 15 minutes until the cheese is melted and bubbling.
