Ingredients for Cheesy Chicken Shells (Serves 6–8)

For the Pasta

  • 20–25 jumbo pasta shells

  • Salt (for boiling water)

For the Chicken Filling

  • 3 cups cooked chicken, shredded

  • 1 cup ricotta or cottage cheese

  • 1 cup shredded mozzarella

  • ½ cup grated parmesan

  • 1 teaspoon garlic powder

  • 1 teaspoon onion powder

  • ½ teaspoon paprika

  • Salt and pepper to taste

  • 1 tablespoon parsley (fresh or dried)

For the Creamy Cheese Sauce

  • 2 tablespoons butter

  • 2 tablespoons all-purpose flour

  • 2 cups milk (or 1 cup milk + 1 cup heavy cream for extra richness)

  • 1 cup shredded cheddar

  • 1 cup shredded mozzarella

  • ½ cup grated parmesan

  • 1 teaspoon Italian seasoning

  • ½ teaspoon salt

  • ¼ teaspoon black pepper

  • Optional: 1 teaspoon minced garlic

For Topping

  • 1 cup mozzarella or cheddar

  • Chopped parsley or basil

🍳 Instructions: How to Make Cheesy Chicken Shells

STEP 1 — Cook the Pasta

  1. Bring a large pot of salted water to a boil.

  2. Add the jumbo shells and cook them until just al dente—usually 8–9 minutes.

  3. Drain and rinse under cold water to stop the cooking.

Tip: Undercooking slightly helps the shells hold their shape while baking.

STEP 2 — Prepare the Chicken Filling

In a large bowl, combine:

  • shredded chicken

  • ricotta or cottage cheese

  • mozzarella

  • parmesan

  • garlic powder

  • onion powder

  • paprika

  • parsley

  • a pinch of salt & pepper

Mix until everything is fully combined. The filling should be creamy but firm enough to hold inside the shells.

If you want extra creaminess, add ¼ cup of cream cheese.

STEP 3 — Make the Creamy Cheese Sauce

  1. In a large saucepan, melt the butter over medium heat.

  2. Whisk in the flour to form a roux. Cook for 1 minute.

  3. Slowly pour in the milk (or milk + cream), whisking constantly.

  4. Cook until slightly thickened.

  5. Add the cheddar, mozzarella, parmesan, Italian seasoning, salt, and black pepper.

  6. Stir until the cheese melts and the sauce becomes silky and smooth.

The sauce should be creamy enough to coat a spoon, but not too thick—similar to Alfredo sauce.

STEP 4 — Assemble the Dish

  1. Spread 1 cup of the cheese sauce into the bottom of a baking dish.

  2. Fill each shell with a generous spoonful of chicken mixture.

  3. Arrange the stuffed shells into the dish in a single layer.

  4. Pour the remaining cheese sauce over the top of all the shells.

  5. Sprinkle extra mozzarella or cheddar over everything.

STEP 5 — Bake

  1. Preheat the oven to 375°F (190°C).

  2. Cover the baking dish with foil and bake for 20 minutes.

  3. Remove the foil and bake for another 10 minutes or until the top is golden and bubbly.

Optional: Turn on the broiler for 2–3 minutes for extra browning.

STEP 6 — Serve

Garnish with chopped parsley or basil.
Serve warm with garlic bread, salad, or roasted vegetables.

Tips for Perfect Cheesy Chicken Shells

1. Don’t overcook the pasta

Since shells continue cooking in the oven, leaving them slightly firm helps maintain shape and structure.

2. Use rotisserie chicken

It adds a richer flavor and saves preparation time.

3. Make it extra creamy

Add cream cheese or mascarpone to the filling.

4. For more flavor

Add sautéed onions, spinach, or sun-dried tomatoes to the filling.

5. Make it spicy

Add:

  • ½ teaspoon crushed red pepper flakes

  • diced jalapeños

  • pepper jack cheese

6. Stuff shells generously

Fill them until they are full but not overflowing—this allows them to stay intact during baking.

7. Make ahead

Assemble the dish and refrigerate for up to 24 hours before baking.

Serving Suggestions

Cheesy Chicken Shells pair beautifully with:

  • Garlic bread

  • Caesar salad

  • Roasted broccoli

  • Focaccia

  • Sautéed spinach

  • A glass of white wine (Chardonnay, Pinot Grigio)

For a full meal, serve with a side of tomato basil soup.

Variations

1. Cheesy Chicken Alfredo Shells

Replace the sauce with creamy Alfredo. Add broccoli or peas.

2. Mexican Chicken Shells

Add taco seasoning, black beans, corn, and pepper jack cheese.
Top with salsa and cilantro.

3. BBQ Chicken Shells

Use BBQ sauce in the filling and cheddar cheese on top.

4. Spinach Chicken Shells

Mix spinach and ricotta with chicken for a lighter, healthier version.

5. Buffalo Chicken Shells

Top with mozzarella.
