Set your oven to 375°F (190°C) to warm up.
Boil the lasagna noodles following the package instructions until tender but firm. Drain and spread them flat on a baking sheet so they don’t stick.
In a large mixing bowl, stir together the shredded chicken, ricotta, half of the Parmesan, minced garlic, egg, Italian seasoning, salt, and pepper until well blended.
Evenly spread the chicken mixture along each noodle, then roll each one up carefully but firmly.
Pour 1 cup of marinara sauce on the base of a 9x13 inch baking pan.
Arrange the rolled noodles with the seam side facing down in the baking dish. Spoon the remaining marinara sauce over the rolls.
Sprinkle the shredded mozzarella and the leftover Parmesan cheese evenly over the top.
Cover the dish with aluminum foil and bake for 20 minutes. Then, remove the foil and continue baking for another 10 minutes until the cheese on top is bubbling and golden.
Before serving, sprinkle chopped fresh parsley over the roll-ups for a bright finish.
