Step‑by‑Step Instructions for Cheesy Spinach & Ricotta Stuffed Shells
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures that your cheesy spinach & ricotta stuffed shells will cook evenly and reach that perfect bubbly texture. While the oven warms up, gather all your ingredients and equipment, including a large pot for boiling, a mixing bowl, and a 9×13-inch casserole dish.
Step 2: Cook the Pasta Shells
In a large pot, bring salted water to a boil and add the jumbo pasta shells. Cook them until al dente, approximately 10-12 minutes, stirring frequently to prevent sticking. Once cooked, drain the shells thoroughly and rinse them under cold water to halt the cooking process and keep them firm for stuffing.
Step 3: Prepare the Filling
In a large mixing bowl, combine the ricotta cheese, grated parmesan, thawed spinach, egg, salt, and pepper. Mix well until it forms a thick and creamy filling. Ensure the spinach is well incorporated and any excess moisture is squeezed out to prevent sogginess in your stuffed shells.
Step 4: Fill the Shells
To fill each shell, use a piping bag or a freezer bag with a corner snipped off. Carefully pipe about 2 tablespoons of the ricotta mixture into each shell, making sure they’re generously stuffed but not overflowing. Set the filled shells aside as you prepare the baking dish.
Step 5: Assemble the Casserole
Spread half of the marinara sauce evenly across the bottom of the 9×13-inch casserole dish. Place the filled shells in a single layer on top of the sauce. This layer will keep the stuffed shells moist while they bake, enhancing the flavors of your cheesy dish.
Step 6: Add Sauce and Cheese
Pour the remaining marinara sauce over the filled shells, making sure they are all covered to keep them juicy during baking. Sprinkle the shredded mozzarella evenly on top. This melty layer will create a deliciously gooey finish that complements the flavors of the cheesy spinach & ricotta stuffed shells.
Step 7: Bake to Perfection
Cover the casserole dish with foil and place it in your preheated oven. Bake for 20-25 minutes or until the sauce is bubbling and the mozzarella is melted. Remove the foil for the last few minutes to allow the cheese to brown slightly, enhancing its flavor and texture.
Step 8: Garnish and Serve
Once baked, remove the dish from the oven and let it sit for a few minutes. Garnish the cheesy spinach & ricotta stuffed shells with fresh basil for a pop of color and flavor. Serve them hot, and revel in the comfort and joy that comes with every cheesy bite!

Cheesy Spinach & Ricotta Stuffed Shells Recipe FAQs
How do I choose the right jumbo pasta shells?
Absolutely! When selecting jumbo pasta shells, look for ones that are intact and free from cracks. Choose a brand that specifies “jumbo” on the package to ensure they’re large enough to hold your filling. It’s also a good idea to check the cooking times on the package, as different brands may vary slightly.
How should I store my leftover stuffed shells?
Very! Leftover stuffed shells can be stored in an airtight container in the refrigerator for up to 3 days. They store best if covered with additional marinara sauce to maintain moisture. When ready to enjoy, just reheat in the oven or microwave until heated through—approx. 10-15 minutes in the oven at 350°F (175°C) works beautifully!
Can I freeze these stuffed shells?
Absolutely! You can freeze both assembled and baked stuffed shells. For best results, wrap the dish tightly with plastic wrap or aluminum foil, ensuring no air gets in.

What if my filling is too watery?
Don’t worry, this is a common issue! If your filling ends up too watery, consider squeezing out any excess moisture from the spinach before mixing it with the other ingredients. If it’s already combined, you can try adding a tablespoon or two of grated Parmesan cheese to help thicken it up. It’s all about achieving that creamy, thick consistency that holds together beautifully!
