Ingredients

  • 1 pound chicken breast, cooked and shredded
  • 1 box jumbo pasta shells
  • 1 tablespoon Cajun seasoning
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon paprika
  • 1/2 teaspoon oregano
  • 1/2 teaspoon thyme
  • 1/4 teaspoon cayenne pepper
  • 1 can diced tomatoes, drained
  • 1 cup heavy cream
  • 1 cup shredded mozzarella cheese
  • Salt and pepper, to taste

Ingredient Notes & Swaps

  • Chicken: Rotisserie or leftover grilled chicken works great here.
  • Seasoning: Adjust cayenne for more or less heat. Homemade Cajun seasoning gives you full control over the spice blend.
  • Cheese: Mozzarella keeps it melty and mild, but you could add pepper jack or smoked gouda for more kick.
  • Cream: Swap in half-and-half for a lighter sauce, or use a Cajun Alfredo if you’re feeling adventurous.

Instructions

  1. Preheat oven to 350°F. Lightly grease a 9×13 baking dish.
  2. Cook pasta shells according to package directions until al dente. Drain and set aside.
  3. Season the chicken: In a large bowl, combine shredded chicken with Cajun seasoning, garlic powder, onion powder, paprika, oregano, thyme, cayenne pepper, salt, and pepper. Mix well.
  4. Stuff the shells: Fill each cooked shell with the seasoned chicken and arrange in the prepared baking dish.
  5. Make the sauce: In a separate bowl, combine drained diced tomatoes and heavy cream. Mix and pour evenly over the stuffed shells.
  6. Add cheese: Sprinkle shredded mozzarella over the top.
  7. Bake: Cover with foil and bake for 25–30 minutes until hot and bubbly.
  8. Serve hot, garnished with parsley if desired.

Tips for Success

  • Don’t overcook the pasta—it should be slightly firm so it holds its shape during baking.
  • Shred chicken finely for easy stuffing and better flavor distribution.
  • Add a spicy topping: A drizzle of hot sauce or sliced jalapeños makes a great final touch.
  • Make ahead: Assemble the dish up to 24 hours ahead, refrigerate, and bake when ready.

Serving Suggestions & Pairings

These creamy Cajun shells are rich, so balance them with crisp or refreshing sides:


Storage & Leftovers

  • Refrigerate leftovers in an airtight container for up to 3 days.
  • Freeze before or after baking—just be sure to cover tightly.
  • Reheat in the oven at 325°F until warm, or microwave single servings with a splash of cream to revive the sauce.
