Ingredients
- 2 cups cooked chicken breast, shredded or finely chopped
- 20–24 large pasta shells, cooked al dente
- 4 tablespoons butter, divided
- 4 garlic cloves, minced
- 1½ cups heavy cream
- 1 cup grated Parmesan cheese
- 1½ teaspoons Italian seasoning
- Salt and black pepper, to taste
- 2 cups shredded mozzarella cheese
- Fresh parsley or extra Parmesan, for garnish (optional)
Instructions

- Step 1: Preheat the Oven
- Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
- Step 2: Cook the Pasta Shells
- Boil salted water and cook shells until al dente. Drain and set aside.
- Step 3: Cook the Chicken
- If using raw chicken, cook in 2 tbsp butter for 6–7 minutes per side, season, and shred. For precooked chicken, just shred it.
- Step 4: Make the Garlic Alfredo Sauce
- In the same skillet, melt remaining 2 tbsp butter. Add garlic and sauté 1 minute. Add cream, bring to simmer, stir in Parmesan, Italian seasoning, salt and pepper. Simmer 2–3 minutes. Stir in shredded chicken and coat evenly. Remove from heat.
- Step 5: Stuff the Shells
- Use a spoon to fill each pasta shell with the creamy chicken Alfredo mixture. Arrange in the greased dish. Pour leftover sauce over the top.
- Step 6: Add the Cheese
- Sprinkle mozzarella evenly over the shells.
- Step 7: Bake the Dish
- Bake uncovered for 20–25 minutes until cheese is melted and golden. Optional: Broil for 1–2 minutes for a crispy top.
- Step 8: Let Cool and Serve
- Let rest 5 minutes before serving. Garnish with parsley or Parmesan, if desired.
