Creamy Cajun Chicken Shells is the comforting family meal I pull out when I want full-bodied flavor and a bit of a crowd-pleaser on the table. Jumbo pasta shells cradle a savory chicken and cheese filling, with a creamy Cajun-spiced sauce blanketing every bite. You get the best of both worlds—Italian creamy cheese comfort and that unmistakable depth of Louisiana seasoning.
I first made these shells after discovering half a rotisserie chicken in my fridge and a craving for something that would brighten up a cold evening. It only took one tray for my family to declare it an instant classic that now rotates regularly at our table.
Ingredients
- Twenty jumbo pasta shells: creates the ideal soft pocket for stuffing and looks impressive
- Two cups shredded cooked chicken: use leftover roast or rotisserie for easy prep and flavor
- One tablespoon olive oil: ensures vegetables become tender and fragrant when sautéed
- Half a finely chopped onion: brings gentle sweetness and depth
- One diced red bell pepper: gives color and mild bite with natural sweetness
- Two cloves minced garlic: sharpens all the background flavors
- One teaspoon Cajun seasoning: find a blend with paprika and just a hint of heat
- Half a teaspoon paprika: rounds out the smoky profile and deepens color
- Quarter teaspoon salt: pulls every flavor element forward
- Quarter teaspoon black pepper: gives a gentle background kick
- One cup ricotta cheese: adds smoothness and subtle tang
- One cup shredded mozzarella cheese: brings the gooey stretch you expect in stuffed pasta
- Half a cup grated Parmesan cheese: sharpens and amplifies the savory taste
- Two tablespoons butter: forms the classic base for a silky sauce
- Two tablespoons all-purpose flour: thickens the sauce just right
- Two cups milk: aim for whole milk to keep it creamy
- Half a cup heavy cream: this is your ticket to true rich decadence
- One teaspoon Cajun seasoning: boosts the Cajun experience in every drop of sauce
- Quarter teaspoon garlic powder: doubles down on garlic’s presence
- Salt and pepper to taste: finetune the sauce to your liking
Instructions
- Preheat and Prepare the Pasta:
- Cook the shells in well-salted boiling water until just shy of al dente so they will not tear when stuffed. Drain and lay them in a single layer to cool.
- Sauté the Vegetables:
- Warm olive oil in a skillet over medium heat. Add onion and red bell pepper and stir gently for five minutes. Let them soften and sweeten without browning. Add minced garlic and keep stirring for about one minute so the garlic turns fragrant but does not toast.
- Mix the Filling:
- Combine shredded chicken with the sautéed vegetables directly in the skillet. Sprinkle with Cajun seasoning paprika salt and black pepper. Mix well off the heat so the spices envelop all the ingredients.
- Combine with Cheeses:
- Transfer the spicy chicken mixture to a bowl. Immediately add ricotta mozzarella and Parmesan cheeses. Stir just enough to create a rich cohesive filling but do not overwork it so the filling stays light.
- Make the Creamy Cajun Sauce:
- Melt butter in a saucepan over medium heat until foamy but not browned. Sprinkle in flour and whisk steadily for one minute. Gradually pour milk and cream while whisking to create a smooth base. Add Cajun seasoning garlic powder salt and pepper. Stir frequently and let it simmer until thickened four to seven minutes.
- Stuff the Shells and Assemble:
- Spread half the sauce into the bottom of a baking dish so the shells do not stick. Gently stuff each cooled pasta shell with filling using a spoon. Line them up snugly in the pan.
- Finish and Bake:
- Pour the remaining sauce over each shell ensuring nothing dries out. Top with an extra layer of mozzarella if you love a golden cheesy finish. Cover with foil and bake for twenty minutes. Remove the foil and bake ten minutes more until the cheese bubbles and browns beautifully.
- Serve:
- Let the dish rest on the counter for five minutes. Sprinkle with chopped parsley before serving for a fresh color contrast and bright herbal finish.

The way Cajun seasoning lifts every creamy bite makes this dish a favorite in my house. I will never forget the first time I tried doubling the spice for an extra kick and how quickly everyone begged for seconds—nothing beats seeing empty plates scraped clean.
Storage Tips
Creamy Cajun Chicken Shells keep perfectly in the refrigerator in a sealed container for three days. For freezing, wrap the entire baking dish tightly in plastic and foil or portion into airtight containers. To reheat, cover with foil and use a low oven or microwave in short bursts so the sauce stays luscious and does not split.
Ingredient Substitutions
If you cannot find jumbo shells, manicotti tubes are sturdy and hold plenty of filling. Use rotisserie chicken or even leftover turkey for ease and extra flavor. For a lower-lactose version, reach for lactose-free cheese blends and dairy-free milk alternatives like oat milk which still create a velvety sauce with just a bit of extra thickening.
Serving Suggestions
These stuffed shells shine right out of the oven with a big bowl of leafy green salad and a tangy vinaigrette. Roasted asparagus or sautéed spinach also pair nicely. For a heartier meal, add garlic bread or focaccia to catch any sauce left on the plate.
Cultural Context
This recipe fuses the classic Italian comfort of stuffed shells with the bold tradition of Cajun flavors rooted in Louisiana cooking. By using rich cheeses and familiar pasta, you get the satisfaction of Italian-American favorites. The Cajun seasoning and peppers celebrate a regional American style that is vibrant and full of spirit.
Seasonal Adaptations
In spring substitute in mild green onions for regular onions for a lighter flavor. Summer bell peppers fresh from the market give the filling even more sweetness. For fall or winter try adding a small amount of sautéed mushrooms for a hearty twist.

Friends and family always ask for this recipe after sharing a meal, even those who say they do not like spicy food. My cousin requested this as her birthday dinner after one memorable bite. It always gets rave reviews for taste and melt-in-your-mouth texture.
