Preheat your oven to 350°F. Lightly coat a 9x13-inch baking dish with cooking spray.
Bring a large pot of salted water to a boil. Cook the lasagna noodles until al dente, about 10 minutes. Drain and lay them flat on a clean surface or paper towel.
While the noodles are cooking, prepare the homemade Alfredo sauce. In a medium saucepan, melt ½ cup unsalted butter over medium heat. Add 3 cloves of minced garlic and cook for about 30 seconds until fragrant. Whisk in 2 cups heavy cream and 1 ½ cups grated Parmesan cheese. Bring to a simmer, whisking constantly. Let it bubble gently for 5 minutes, then turn off the heat.
In a large bowl, stir together 2 cups shredded chicken, 1 cup ricotta cheese, 1 large egg, 1 cup of shredded mozzarella cheese, ½ cup of grated Parmesan cheese, 2 teaspoons granulated garlic, 2 teaspoons Italian seasoning, 1 teaspoon kosher salt, and ½ teaspoon ground black pepper until well combined.
Spread about ¼ cup of the chicken mixture onto each lasagna noodle, then roll them up tightly.
Pour about ½ cup of the homemade Alfredo sauce into the prepared baking dish. Place the roll-ups seam-side down in the dish.
Pour the remaining Alfredo sauce evenly over the top of the rolls, ensuring they’re well-coated. Sprinkle the remaining 1 cup of mozzarella cheese across the top.
Cover with foil and bake for 15-20 minutes. Uncover and bake for an additional 10 minutes, or until the cheese is melted and golden brown.
Let the chicken lasagna roll-ups rest for 10 minutes before serving. Garnish with chopped parsley if you’d like.
