Heat your oven to 375°F. Grab a 9x13-inch baking dish and give it a light coating of cooking spray or butter.
02 -
Bring a large pot of salted water to a boil. Add the jumbo shells and cook until they're just tender but still firm. Drain them and set aside to cool enough to handle.
03 -
In a big mixing bowl, combine the shredded chicken, chopped broccoli, ricotta, mozzarella, Parmesan, egg, and seasonings. Mix everything together until it's well blended.
04 -
Take each cooled pasta shell and spoon a generous amount of the chicken and broccoli mixture inside. Arrange the stuffed shells in your prepared baking dish with the openings facing up.
05 -
Pour the Alfredo sauce evenly over all the stuffed shells. Make sure each shell gets some sauce coverage. Sprinkle extra mozzarella on top for that perfect cheese pull.
06 -
Cover the baking dish with aluminum foil and slide it into the oven. Bake for about 25 minutes until everything is heated through.
07 -
Remove the foil and continue baking for another 10-15 minutes until the cheese on top is bubbly and starting to turn golden brown.
08 -
Take the dish out of the oven and let it rest for about 5 minutes. Sprinkle with fresh parsley if desired, then serve while still warm and gooey.
