Preheat oven to 375°F. Bring a large pot of salted water to a boil and cook jumbo pasta shells according to package directions until al dente. Drain thoroughly and arrange the shells on a baking sheet to cool completely.

Heat olive oil in a skillet over medium heat. Sauté finely chopped onion and diced red bell pepper for about 5 minutes until softened. Stir in minced garlic and cook for 1 minute until fragrant.
03 -
Add shredded chicken to the skillet along with Cajun seasoning, paprika, salt, and black pepper. Mix well so spices evenly coat the chicken. Remove from heat and allow the mixture to cool for several minutes.
04 -
In a large bowl, fold together the chicken mixture with ricotta, mozzarella, and Parmesan cheese until fully incorporated.

Melt butter in a saucepan over medium heat. Whisk in flour and cook for 1 minute to form a roux. Gradually stream in milk and heavy cream, whisking constantly to avoid lumps. Season with Cajun seasoning, garlic powder, salt, and black pepper. Simmer, whisking frequently, 5-7 minutes until slightly thickened.
06 -
Spread half the Cajun cream sauce on the bottom of a 9x13-inch baking dish. Stuff each cooked shell generously with the chicken and cheese filling, placing shells seam-side up over the sauce in a single layer.
07 -
Pour remaining Cajun sauce evenly over the stuffed shells. Sprinkle additional shredded mozzarella cheese evenly across the top for extra coverage.
08 -
Cover the baking dish with foil and bake for 20 minutes. Remove foil and continue baking for 10 minutes until sauce is bubbling and cheese turns golden brown.

Allow baked shells to rest for several minutes before serving. Garnish with chopped fresh parsley if desired.
