Million Dollar Chicken Alfredo Stuffed Shells Recipe

Preheat oven to 375ºF. Lightly spray a 9×13-inch baking dish with cooking spray.
Cook pasta shells al dente according to package instructions. Drain and set aside.
In a large bowl, mix chicken, cottage cheese, cream cheese, sour cream, Parmesan, 1 cup mozzarella, and dried parsley until well combined.
Stuff each shell with filling and arrange in prepared baking dish.
Pour Alfredo sauce over the shells, ensuring they are fully covered.
Sprinkle remaining 1 cup mozzarella on top.
Bake uncovered for 30–35 minutes, until cheese is bubbly and golden.
Let rest a few minutes, garnish with parsley if desired, and serve warm.
Notes
Use ricotta instead of cottage cheese if preferred.
Add spinach, red pepper flakes, or use alternate proteins for variation.
Can be assembled ahead and stored in the fridge or freezer.
