Bring a large pot of salted water to a boil. Add the lasagna noodles and cook according to package instructions until al dente. Drain, lay the noodles out on a flat surface, and pat dry with paper towels. (I suggest using a piece of parchment paper).
Preheat your oven to 350 degrees F.
In a large mixing bowl, stir together the shredded chicken, ricotta cheese, salt, Italian seasoning, onion powder, and garlic powder until well combined.
Spread about 3 ounces of the chicken mixture (1/3 to 12/ cup) over each noodle, being sure to leave 1/3 of each noodle bare. Drizzle 1 tablespoon of Alfredo sauce over the chicken filling on each noodle.
Starting at the cover end of each noodle, roll them up toward the bare end until they're all rolled up.
Add 1/2 cup of Alfredo sauce to the bottom of a 9x13 baking dish. Place each lasagna roll up into the casserole dish seam side down. Pour the remaining 1 1/2 cups of Alfredo sauce over the lasagna roll ups. Top with shredded mozzarella and Parmesan cheese.
Cover the dish with aluminum foil and bake for 20 minutes. After 20 minutes, remove the foil and continue to bake for 10 minutes or until the cheese is melted and bubbling.
Remove from the oven and let rest for 5 minutes. Sprinkle chopped parsley over the top before serving warm with extra sauce drizzled over the top, if desired.
Notes
For the chicken, you can cook 1 pound of chicken breasts or use one rotisserie chicken (discarding the skin and bones). Both options will give you about 3 cups of shredded cooked chicken.
Pro Tip: Cook some extra lasagna noodles. That way, if any of them break during the cooking/draining process, you'll have some backups.
