Creamy Cajun Chicken Shells fill 20 jumbo pasta shells with seasoned chicken, vegetables, ricotta, mozzarella, and Parmesan, then bake them under a gently spiced cream sauce. The casserole serves 6 in 50 minutes, including 20 minutes of preparation and 30 minutes in the oven.
The recipe builds flavor in layers without making the Cajun seasoning overpower the dairy. Pasta is cooked only to al dente, the chicken filling is cooled before cheese is mixed in, and the sauce is thickened enough to coat a spoon before assembly. Those controls keep the shells intact and the finished casserole creamy rather than watery.

How to Make Creamy Cajun Chicken Shells
- Prepare the pasta shells: Preheat your oven to 375°F (190°C). Bring a large pot of salted water to a boil. Cook the jumbo pasta shells according to package instructions until al dente (usually 8-10 minutes). Be careful not to overcook as they will continue cooking in the oven. Drain and arrange on a baking sheet to cool without touching each other to prevent sticking.
- Make the chicken filling: While the pasta is cooking, heat olive oil in a large skillet over medium heat. Add the chopped onion and diced red bell pepper, sautéing until soft and slightly translucent, about 5 minutes. Add the minced garlic and cook for another minute until fragrant, stirring constantly to prevent burning.
- Season and complete the filling: Add the shredded chicken to the skillet with the vegetables. Sprinkle with Cajun seasoning, paprika, salt, and black pepper. Stir well to combine and coat the chicken with the seasonings. Remove from heat and let cool slightly for about 5 minutes.
- Mix with cheeses: Transfer the chicken mixture to a large mixing bowl. Add the ricotta cheese, 1 cup of shredded mozzarella, and the grated Parmesan cheese. Mix thoroughly until all ingredients are well combined and the cheeses are evenly distributed throughout the filling.
- Prepare the creamy sauce: In a medium saucepan, melt the butter over medium heat. Whisk in the flour to create a roux, cooking for about 1 minute while stirring constantly. Gradually add the milk and heavy cream, whisking continuously to prevent lumps from forming. Add the Cajun seasoning, garlic powder, salt, and pepper. Bring to a gentle simmer and cook for 5-7 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon.
- Assemble the dish: Spread approximately half of the creamy sauce in the bottom of a 9x13-inch baking dish. Take each cooled pasta shell and fill it generously with the chicken and cheese mixture, about 1-2 tablespoons per shell depending on size. Arrange the filled shells in the baking dish, open side up, in a single layer.
- Top and prepare for baking: Pour the remaining creamy sauce evenly over the stuffed shells, making sure to cover them all. Sprinkle additional mozzarella cheese on top according to your preference. Cover the baking dish with aluminum foil, ensuring it doesn't touch the cheese topping.
- Bake: Place the covered dish in the preheated oven and bake for 20 minutes. Then remove the foil and continue baking for an additional 10 minutes until the cheese is melted, bubbly, and beginning to brown in spots.
- Serve: Remove from the oven and let the dish rest for about 5 minutes before serving. This allows the sauce to set slightly and makes serving easier. Garnish with freshly chopped parsley if desired. Serve hot, with 3-4 shells per serving.

Why the Recipe Works
Cook all 20 shells in salted water for the package time, usually 8–10 minutes, and stop at al dente because they continue cooking at 375°F (190°C). Spreading them apart on a baking sheet prevents sticking and makes each shell easier to fill without tearing.
The finely chopped half onion and diced red bell pepper need about 5 minutes in olive oil before the two minced garlic cloves are added for one minute. Add the 2 cups cooked shredded chicken and its measured seasonings, then cool the mixture for about 5 minutes. Ricotta, mozzarella, and Parmesan stay creamier when they are not stirred into a sizzling-hot skillet.

Critical Cooking Cues
For the sauce, cook equal 2-tablespoon measures of butter and flour for about 1 minute. Add 2 cups milk and ½ cup heavy cream gradually while whisking, then season and simmer 5–7 minutes. The back-of-a-spoon test is more reliable than a rigid clock: the sauce should leave an opaque coating but remain fluid enough to spread.
Place half the sauce in a 9×13-inch dish, fill each shell with about 1–2 tablespoons chicken mixture, and arrange all 20 open side up. Cover with the remaining sauce and extra mozzarella. Bake covered for 20 minutes, then uncovered for 10 minutes until bubbling and lightly browned. A 5-minute rest helps the sauce settle before serving 3–4 shells per person.
Serving, Storage, and Reheating
Parsley is optional and should be added after baking. A crisp salad or simply cooked green vegetable balances the creamy filling without changing it. Refrigerate leftovers covered, then reheat gently so the dairy sauce does not separate. For freezing, cool the assembled casserole completely and protect it closely from air; thaw in the refrigerator before reheating. If preparing ahead, keep the cooked shells separated and do not overcook them.
Recorded Recipe Tips
- Using rotisserie chicken is a great time-saver for this recipe.
- Make sure your sauce is properly thickened before pouring over the shells to prevent it from becoming too watery during baking.
- If the sauce becomes too thick, thin it with a little more milk until it reaches your desired consistency.
- This dish reheats well - cover with foil and bake at a lower temperature (325°F) until heated through, about 20 minutes.
