Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
02 -
Cook the pasta shells until just al dente, about 1–2 minutes less than the package suggests. Drain, rinse under cool water, and set aside to dry.
03 -
In a large mixing bowl, combine the diced chicken, steamed broccoli, 1 cup of shredded cheese, garlic powder, salt, and pepper. Stir in sour cream, cream cheese, or pasta water if using.
04 -
Spoon about 2 tablespoons of filling into each shell and place them snugly in your prepared baking dish.
05 -
In a separate bowl, whisk together the cream of chicken soup and milk until smooth. Stir in any optional add-ins like Dijon or dried herbs.
06 -
Pour the sauce evenly over the stuffed shells. Sprinkle with remaining cheese and any additional Parmesan if desired.
07 -
Bake uncovered for 25 minutes, until bubbly and heated through. Optionally, broil for 2–3 minutes for a golden crust.
08 -
Let the shells rest for 5 minutes before serving for the best texture and flavor.
