Preheat your oven to 350°F (175°C) and grease your baking dish with butter.

Bring a large pot of salted water to a boil and cook the pasta until al dente, about 8-10 minutes. Drain and set aside.

In a skillet over medium heat, combine diced chicken with cream cheese, sour cream, and smoked paprika, cooking until the chicken is fully cooked and the mixture is creamy, about 5-7 minutes.

Fold in the cooked pasta and any diced vegetables.

Pour the mixture into the greased baking dish, spreading it evenly.

Sprinkle the shredded cheddar cheese on top and dust with more smoked paprika.

Cover with foil and bake for 25 minutes, then remove foil and bake for an additional 10 minutes or until the cheese is bubbly and golden brown.

Let it rest for 5-10 minutes before serving.
