Cook jumbo pasta shells in a large pot of salted boiling water according to package directions until al dente. Drain and set aside to cool so they are firm enough to stuff.
02 -
Heat olive oil in a large skillet over medium heat. Add onion and bell pepper, sauté for 5 minutes until softened. Stir in minced garlic and cook for 1 minute until fragrant.
03 -
Combine shredded chicken with sautéed vegetables. Add Cajun seasoning, paprika, salt, and black pepper. Stir thoroughly, then remove from heat and cool for several minutes.
04 -
In a mixing bowl, blend the cooled chicken mixture with ricotta, mozzarella, and Parmesan cheeses until smooth and uniform.
05 -
Melt butter in a saucepan over medium heat. Add flour, whisking continuously for 1 minute. Gradually pour in milk and heavy cream, whisking to prevent lumps. Season with Cajun seasoning, garlic powder, salt, and black pepper. Simmer, stirring, until the sauce thickens and coats the back of a spoon, about 5–7 minutes.
06 -
Spread half of the prepared cream sauce over the bottom of a 9 x 13-inch baking dish. Fill each pasta shell with the chicken-cheese mixture and arrange shells in a single layer over the sauce.
07 -
Pour remaining sauce evenly over the filled shells. Sprinkle with extra mozzarella cheese. Cover tightly with aluminum foil and bake at 375°F (190°C) for 20 minutes. Uncover and bake for an additional 10 minutes until the top is golden and the dish is bubbling.

Allow the baked shells to rest for several minutes before serving. Garnish with freshly chopped parsley for brightness.
