Ingredients and Their Roles

For the Stuffed Shells:

• 20 jumbo pasta shells – The perfect vessel for holding the rich filling. They become tender when boiled and hold their shape well in the oven.
• 2 cups cooked, shredded chicken – Adds lean protein and a savory base. Rotisserie chicken is a convenient and flavorful choice.
• 1 ½ cups ricotta cheese – Provides creaminess and helps bind the filling together. It creates that classic stuffed-shell texture.
• 1 cup chopped fresh spinach – Adds color, nutrients, and a subtle earthy flavor that balances the richness of the cheeses.
• 1 cup shredded mozzarella cheese (plus more for topping) – Melts beautifully, adding stretch and gooey texture to both the filling and topping.
• ¼ cup grated Parmesan cheese – Adds a salty, nutty punch and depth to the flavor.
• 1 egg – Acts as a binder to hold the filling together during baking.
• 1 teaspoon garlic powder – Enhances the savory flavor of the filling without overpowering.
• ½ teaspoon salt – Seasoning to bring all the flavors together.
• ½ teaspoon black pepper – Adds mild heat and balances the richness.

For Assembly and Baking:

• 2 cups marinara sauce – A tangy, slightly sweet tomato sauce that coats the shells and adds moisture during baking.
• 1 cup shredded mozzarella (for topping) – Creates that irresistible golden, bubbling cheese topping.
• Chopped fresh basil or parsley (optional, for garnish) – Adds freshness and a burst of color before serving.

Step-by-Step Instructions

Step 1: Boil the Pasta Shells

Bring a large pot of salted water to a boil. Cook the jumbo pasta shells until just al dente, about 9–10 minutes. Be careful not to overcook; they’ll finish cooking in the oven. Drain and lay them out on a baking sheet to cool slightly without sticking.

Step 2: Make the Chicken and Spinach Filling

In a large bowl, combine the shredded chicken, ricotta cheese, chopped spinach, 1 cup mozzarella, Parmesan, egg, garlic powder, salt, and pepper. Mix until well blended and creamy.

Pro Tip: If using fresh spinach, sauté it briefly in a bit of olive oil until wilted, then squeeze out any excess moisture before chopping.

Step 3: Prepare the Baking Dish

Preheat the oven to 375°F (190°C). Spread 1 cup of marinara sauce on the bottom of a 9×13-inch baking dish. This prevents the shells from sticking and adds flavor from the bottom up.

Step 4: Stuff the Shells

Using a spoon, fill each shell with 1 to 2 tablespoons of the chicken and spinach mixture. Arrange the stuffed shells snugly in the baking dish over the marinara sauce.

Step 5: Top and Bake

Once all the shells are filled and arranged, pour the remaining 1 cup of marinara sauce over the top. Sprinkle with the remaining 1 cup of shredded mozzarella.

Cover the dish loosely with foil and bake for 25 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and slightly golden.

Step 6: Garnish and Serve

Remove from the oven and let rest for 5 minutes. Garnish with chopped fresh basil or parsley before serving.

Pro Tips for Perfect Stuffed Shells

• Don’t overcook the shells. Slightly undercooked shells will hold up better during baking and won’t fall apart.
• Use quality marinara. A good sauce makes a big difference in overall flavor. Go homemade or pick a trusted store-bought brand.
• Double the batch. These stuffed shells freeze beautifully. Make one for now, and save one for later — your future self will thank you.
• Let it rest before serving. Just 5 minutes allows the cheese to set slightly and makes serving easier.
