Chicken & Spinach Stuffed Shells were born out of one of those evenings when I wanted something cozy but still a little special. I remember it clearly: a busy day, a fridge with odds and ends, and that familiar craving for a meal that wraps you up like a warm blanket. I had leftover chicken, a bag of spinach that needed using, and jumbo pasta shells waiting patiently in the pantry. What came out of that night was a recipe my family now requests again and again.

Step-by-Step Instructions for Chicken & Spinach Stuffed Shells
1. Cook the Pasta Shells
Bring a large pot of well-salted water to a boil and cook the jumbo pasta shells until just al dente. This step is essential for Chicken & Spinach Stuffed Shells, as overcooked shells can tear when filled. Drain the shells and lay them flat on a baking sheet to cool completely.
2. Prepare the Spinach
Heat olive oil in a skillet over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant. Add the spinach and cook until fully wilted. Lightly season with salt and pepper, then remove from heat and finely chop. Properly preparing the spinach prevents excess moisture in your Chicken & Spinach Stuffed Shells filling.
3. Make the Filling
In a large mixing bowl, combine ricotta cheese, egg, shredded mozzarella, grated Parmesan, Italian seasoning, cooked chicken, and chopped spinach. Mix gently until everything is just combined. For the creamiest Chicken & Spinach Stuffed Shells, avoid overmixing, which can make the filling dense instead of light and fluffy.
4. Assemble the Dish
Spread about 1½ cups of marinara sauce evenly across the bottom of a baking dish. Stuff each pasta shell generously with the chicken and spinach filling, then arrange them seam-side up. Proper assembly ensures every bite of your Chicken & Spinach Stuffed Shells is perfectly balanced with sauce and filling.
5. Top and Bake
Pour the remaining marinara sauce evenly over the stuffed shells and sprinkle with extra mozzarella cheese. Cover the dish loosely with foil and bake at 375°F (190°C) for 25 minutes. Remove the foil and bake for an additional 10–15 minutes, until the Chicken & Spinach Stuffed Shells are bubbly and lightly golden on top.
6. Rest and Serve
Remove the baking dish from the oven and let the Chicken & Spinach Stuffed Shells rest for about 10 minutes before serving. This resting time allows the filling to set, making the shells easier to serve and even more flavorful.

Understanding Common Stuffed Shells Pitfalls (And How to Avoid Them)
One of the most frequent mistakes when making stuffed shells is overcooking the pasta. Another is using a filling that’s too wet, which leads to watery results. With Chicken & Spinach Stuffed Shells, draining spinach thoroughly and balancing cheese ratios ensures a creamy—not soggy—dish.
What’s Really in the Filling?
The filling for Chicken & Spinach Stuffed Shells is a well-balanced combination of protein, dairy, and greens. Chicken provides substance, spinach adds freshness, and the cheeses bind everything into a rich, spoonable mixture that holds its shape after baking.
Why Chicken and Spinach Work So Well Together
Chicken and spinach are not only delicious together, they’re nutritionally complementary. The mild flavor of chicken allows spinach’s earthiness to shine, while spinach adds moisture and balance to lean protein. This pairing has long been a favorite in dishes like our internal favorite, Stuffed Chicken Spinach Rigatoni, and it works just as beautifully here.
Can You Add Spinach to Stuffed Shells?
Absolutely—and it’s one of the best upgrades you can make. Spinach enhances both flavor and nutrition without overpowering the dish. In Chicken & Spinach Stuffed Shells, it melts seamlessly into the cheese mixture, making every bite balanced and satisfying.
Helpful Tips from My Kitchen
