I first whipped this up on a chilly evening and my whole family was hooked after one bite. Now whenever I want to impress with comfort food but do not want to fuss, this is what I reach for.

Instructions
- Preheat and Prepare the Pasta:
- Cook the jumbo shells according to the package until just tender. Drain the shells with care and lay them out so they do not stick. Preheat your oven to 375 degrees Fahrenheit so the baking dish is ready to go in.
- Sauté the Vegetables:
- Set a skillet over medium heat and add olive oil. Drop in the finely chopped onion and diced bell pepper. Let them soften for five minutes so their flavors sweeten. Add minced garlic for just a minute at the end to wake up its aroma but avoid burning.
- Mix the Filling:
- Add shredded cooked chicken straight into the skillet with the veggies. Sprinkle Cajun seasoning paprika salt and pepper over everything. Toss well so every shred of chicken picks up those warm spicy notes. Turn off the heat and let it sit for a bit so the flavor soaks in.
- Combine with Cheeses:
- Spoon chicken and veggies into a bowl. Add ricotta mozzarella and Parmesan. Blend until smooth and creamy so every scoop slides easily into your shells later.
- Make the Creamy Cajun Sauce:
- In a clean saucepan melt the butter gently over medium heat. Whisk in the flour and keep stirring for a minute until it thickens just slightly and smells toasty. Gradually pour in milk and cream whisking constantly so it turns silky. Sprinkle in Cajun seasoning garlic powder salt and pepper. Keep heating and stirring for about five to seven minutes until the sauce is thick enough to coat a spoon.
- Stuff the Shells and Assemble:
- Spread half of the sauce into the bottom of a large baking dish. Use a spoon to fill each shell with cheese chicken mixture and arrange them closely in the dish on top of the sauce.
- Finish and Bake:
- Pour the remaining sauce over the shells making sure they are well covered. Sprinkle more mozzarella on top so you get a beautiful crust. Cover with foil and bake for twenty minutes. Remove foil and bake for ten more until you see golden cheese and bubbling sauce.
- Serve:
- Let everything rest several minutes when finished baking so the sauce sets up and the flavors have time to marry. Garnish with parsley for a fresh bright contrast if you like.

Tastes just as good the next day and makes super leftovers. One of my favorite things is how the Cajun seasoning turns simple chicken and pasta into bold southern comfort. I still remember serving this at a family party and watching everybody go back for more saying the balance of creamy and spicy was perfect.
Storage Tips
This dish keeps well in your fridge covered for three days and does not dry out. When reheating use gentle heat either in the oven or microwave so the sauce stays creamy. If you want to freeze some for later let the pan cool then tightly cover with foil. Defrost overnight in the fridge and reheat gently so nothing separates or curdles.
Ingredient Substitutions
Manicotti works if you cannot find jumbo shells just be careful not to over-stuff them. Try rotisserie chicken for convenience and pulled texture. For dairy-free tweaks use a tofu based ricotta alternative or a mild plant cheese and almond milk for the sauce. You might want to add a pinch more seasoning since some alternatives are less rich.
Serving Suggestions
Serve these shells with a crisp salad or simple steamed broccoli to cut the richness. A piece of crusty bread or garlic toast soaks up all that amazing sauce. A glass of dry white wine or just sparkling water works great on the side to keep your palate fresh.
Cultural Context
This recipe is a beautiful mashup of spicy Cajun flavors and classic Italian comfort food. The technique of stuffed shells is pure Italian but the seasoning and creamy heat are straight from the American South. It gives you depth and brightness all in one hearty family dish.

Let the finished shells rest a few minutes after baking to keep the filling and sauce set for easy serving. For even more flavor try swapping in pepper jack cheese for extra heat.
