Ingredients for Chicken and Spinach Stuffed Shells
Main Ingredients
- 1 box jumbo pasta shells (about 12–15 oz)
- 2 cups cooked chicken, shredded or diced
- 2 cups fresh spinach, chopped
- 1 cup ricotta cheese
- 8 oz cream cheese, softened
- ½ cup grated Parmesan cheese
- 2 cups shredded mozzarella cheese (divided)
- 1 egg, lightly beaten
- ¼ cup mayonnaise
- ½ small onion, finely diced
- 3 cloves garlic, minced
- 1 tablespoon Italian seasoning
- 1 tablespoon dried parsley
- Salt and black pepper to taste
- 1 jar (24–26 oz) tomato pasta sauce
Ingredient Notes
- Chicken options: Rotisserie chicken works perfectly and saves time.
- Spinach swap: Frozen spinach can be used; just thaw and squeeze out extra moisture.
- Cream cheese substitute: Greek yogurt or extra ricotta can create a lighter filling.
- Sauce options: Marinara or homemade tomato sauce both work well.
- Extra flavor: Add crushed red pepper flakes if you enjoy a little heat.
Step-by-Step Instructions
Step 1 – Cook the Pasta Shells
Bring a large pot of salted water to a boil. Add the jumbo pasta shells and cook until they are just al dente, usually about 1–2 minutes less than the package directions. Drain the shells and rinse with cool water to stop the cooking process. Set aside on a tray so they don’t stick together.
Step 2 – Prepare the Chicken Filling
In a large bowl, combine the shredded chicken and chopped spinach. If using fresh spinach, it can be added directly. The heat from baking will soften it perfectly.
Step 3 – Make the Cheese Mixture
In another bowl, mix the ricotta cheese, cream cheese, Parmesan cheese, mayonnaise, egg, Italian seasoning, parsley, salt, and black pepper. Stir until smooth and well combined.
Add the diced onion and minced garlic for extra flavor.
Step 4 – Combine the Filling
Add the chicken and spinach mixture to the cheese mixture. Stir until everything is evenly combined. Fold in about 1 cup of shredded mozzarella to create a rich, creamy filling.
Step 5 – Prepare the Baking Dish
Spread about one cup of tomato sauce across the bottom of a large baking dish. This prevents the shells from sticking and adds flavor while baking.
Step 6 – Stuff the Shells
Using a spoon, fill each pasta shell with the chicken and spinach mixture. Place the stuffed shells into the baking dish in a single layer.
Continue filling shells until all the mixture is used.
Step 7 – Add Sauce and Cheese
Pour the remaining tomato sauce evenly over the shells. Sprinkle the remaining 1 cup mozzarella cheese over the top.
Step 8 – Bake the Dish
Cover the dish with foil and bake at 375°F (190°C) for about 30 minutes.
Remove the foil and bake an additional 10 minutes until the cheese is melted and bubbly.
Step 9 – Rest and Serve
Allow the dish to rest for about 5 minutes before serving. This helps the filling set and makes the shells easier to serve.
Pro Tips for Success
- Cook shells slightly underdone so they hold their shape when stuffed.
- Use rotisserie chicken for faster preparation and extra flavor.
- Drain spinach well if using frozen to avoid watery filling.
- Don’t overfill shells to prevent the filling from spilling during baking.
- Cover while baking first to keep moisture and prevent drying.
- Let the dish rest before serving so the cheese mixture firms up.
Flavor Variations
Chicken and Spinach Stuffed Shells can easily be customized:
1. Alfredo Style
Replace the tomato sauce with creamy Alfredo sauce for a richer pasta bake.
2. Mushroom and Chicken
Add sautéed mushrooms to the filling for deeper savory flavor.
3. Extra Veggie Version
Mix in chopped zucchini, bell peppers, or broccoli.
4. Spicy Version
Add chili flakes or diced jalapeños to the filling.
5. Mediterranean Twist
Add sun-dried tomatoes and a little feta cheese for a unique flavor profile.
Serving Suggestions
This dish is satisfying on its own, but it pairs well with simple sides:
- Fresh green salad with lemon vinaigrette
- Warm garlic bread or crusty bread
- Roasted vegetables such as zucchini or carrots
- Light cucumber and tomato salad
These sides balance the richness of the cheesy pasta and create a complete meal.
