Key Ingredients

Jumbo Pasta Shells

Jumbo shells are the base of this recipe and make it easy to hold the creamy Cajun chicken filling. Cooking them just until al dente helps them stay firm enough to stuff and bake without falling apart.

Chicken

Cooked chicken keeps this recipe simple and hearty. You can use chopped chicken breast, shredded chicken, leftover baked chicken, or rotisserie chicken to save time.

Cajun Seasoning

Cajun seasoning gives the filling its bold, savory flavor. It brings warmth, spice, and depth that balances the creamy Alfredo sauce.

Alfredo Sauce

Alfredo sauce keeps the stuffed shells creamy and rich. It goes into the filling and over the top, helping the shells stay moist while they bake.

Cheese

Ricotta, mozzarella, and Parmesan create a creamy, cheesy filling with great texture. Ricotta makes the filling smooth, mozzarella adds meltiness, and Parmesan adds salty richness.

Equipment Needed

Large pot for boiling the jumbo shells

Colander for draining the pasta

9×13 baking dish for assembling and baking the stuffed shells

How to Make Cajun Chicken Alfredo Stuffed Shells

Step 1: Prep the Ingredients

Boil the jumbo shells in salted water until they are just al dente. Drain them and let them cool slightly so they are easier to handle. Chop or shred the cooked chicken and measure out the cheeses, Alfredo sauce, and seasonings before assembling.

Step 2: Build the Flavor

Warm the chicken in a skillet with olive oil, Cajun seasoning, garlic powder, onion powder, black pepper, and smoked paprika. This step helps the seasoning coat the chicken before it gets mixed into the cheese filling.

Step 3: Cook Until Tender or Done

Mix the seasoned chicken with ricotta, mozzarella, Parmesan, egg, and a little Alfredo sauce. Spread Alfredo sauce in the bottom of a baking dish, stuff each shell with the filling, then place the shells in the dish. Cover with more Alfredo sauce and cheese, then bake until the sauce is bubbling and the filling is hot.

Step 4: Finish and Serve

Remove the foil near the end of baking so the cheese on top can melt and turn lightly golden. Let the shells rest for a few minutes before serving so the filling sets slightly. Garnish with parsley, extra Parmesan, or a light sprinkle of Cajun seasoning.

Tips for the Best Results

Cook a few extra shells in case some tear while boiling.

Do not overcook the pasta because soft shells are harder to stuff and can break during baking.

Use rotisserie chicken as a shortcut when you want to save time.

Taste your Cajun seasoning before adding extra salt because some blends are saltier than others.

For extra creamy shells, add another 1/2 cup of Alfredo sauce over the top before baking.

Let the stuffed shells rest for 5 minutes before serving so they hold together better.

Make Ahead, Storage, and Reheating

Make Ahead:

You can assemble the stuffed shells up to 24 hours ahead of time. Cover the baking dish tightly and refrigerate until you are ready to bake. If baking straight from the refrigerator, add 10 to 15 extra minutes to the covered baking time.

Storage:

Store leftovers in an airtight container in the refrigerator for up to 4 days. Keep the shells covered so the pasta does not dry out.

Freezing:

These stuffed shells freeze well. Assemble them in a freezer-safe baking dish, cover tightly with plastic wrap and foil, and freeze for up to 2 months. Thaw overnight in the refrigerator before baking for best results.

Reheating:

Reheat individual portions in the microwave with a spoonful of Alfredo sauce or a splash of milk to keep them creamy. To reheat a larger portion, cover with foil and bake at 350°F until warmed through.
