This easy spinach manicotti recipe makes six generous servings of tender pasta shells filled with creamy ricotta, spinach, mozzarella, and Parmesan, then baked under bubbling marinara sauce. With 20–25 minutes of preparation and 35–40 minutes in the oven, it is a comforting dinner that comes together in about an hour.
Every bite combines tangy tomato sauce, silky cheese filling, tender pasta, and savory Italian seasoning. Frozen chopped spinach keeps the recipe practical and consistent, while squeezing it very dry prevents a watery filling and helps the manicotti bake into a rich, satisfying casserole.

Spinach manicotti has the cozy appeal of a baked pasta casserole while still feeling special enough for a Sunday dinner or holiday table. The filling is creamy without being heavy, and the spinach adds color, flavor, and a pleasant savory balance to the cheeses.
This recipe is also wonderfully practical. It uses frozen chopped spinach, jarred marinara or spaghetti sauce, and familiar pantry seasonings, so there is no need to prepare a complicated sauce or search for unusual ingredients.
The finished dish is tender, saucy, and golden on top. Serve it with a crisp salad and warm bread for a complete meal, or pair it with simple roasted potatoes when you want a heartier spread with plenty of comforting flavor.
Ingredients You’ll Need
The ingredient list is short, but each item has an important role in creating the right texture. Ricotta forms the creamy base, mozzarella adds stretch and a golden finish, and Parmesan brings a salty, nutty note that makes the filling taste full and savory.
- Manicotti shells: Use 12 pasta shells and cook them only until just tender, usually 6–7 minutes.
- Frozen spinach: Thaw 10 ounces and squeeze it very dry. A clean kitchen towel, fine-mesh strainer, or several layers of paper towel can help remove excess moisture.
- Cheese: You will need 15 ounces of ricotta, 1 1/2 cups shredded mozzarella, and 1/2 cup grated Parmesan.
- Egg: One large egg helps bind the spinach and cheese filling.
- Sauce: Use 24 ounces of your favorite marinara or spaghetti sauce.
- Seasonings: Italian seasoning, garlic powder or one minced garlic clove, salt, and black pepper provide the familiar Italian-style flavor.

How to Make It Step-by-Step
Step 1: Heat the oven to 375°F (190°C), then lightly grease a 9-by-13-inch baking dish. Spread about 1 cup of the marinara sauce across the bottom so the shells sit on a flavorful layer and do not stick.
Step 2: Bring a large pot of salted water to a boil and cook the manicotti shells for 6–7 minutes, until just tender. Drain them carefully and cool them slightly, remembering that fully soft pasta can tear more easily and will continue cooking during baking.
Step 3: Add the ricotta, very dry spinach, egg, 1 cup mozzarella, Parmesan, Italian seasoning, garlic, salt, and pepper to a mixing bowl. Stir thoroughly until the spinach is distributed throughout and the filling looks thick, creamy, and evenly seasoned.
Step 4: Spoon the filling into a piping bag or a large zip-top bag with one corner snipped off. Pipe the mixture into each shell from both ends, or use a small spoon and gently nudge the filling toward the center without forcing the pasta.
Step 5: Place the filled shells in a single layer in the prepared baking dish. Cover them with the remaining marinara sauce, making sure the pasta is well coated, and scatter the remaining 1/2 cup mozzarella over the top.
Step 6: Cover the dish tightly with foil and bake for 25 minutes. Remove the foil and bake for another 10–15 minutes, until the sauce is bubbling around the edges and the mozzarella is melted with lightly browned spots.
Step 7: Remove the baking dish from the oven and let it rest for 5 minutes before serving. Spoon sauce over each shell and use a broad spatula to lift the manicotti carefully from the dish.
Pro Tips for Perfect Manicotti
The most important preparation detail is removing as much water as possible from the thawed spinach. Frozen spinach can hold a surprising amount of moisture, and if it goes into the filling wet, the mixture may become loose while the sauce can turn thin.
Do not boil the manicotti until completely soft. Six to seven minutes is usually enough for shells that are flexible but sturdy, and slightly firm pasta is easier to fill and less likely to split during assembly.
A piping bag is the fastest filling method, but a zip-top bag works just as well. Fill from one end, then turn the shell around and fill from the other end so the cheese mixture reaches both sides.
Keep the foil pressed snugly over the baking dish during the first 25 minutes. This traps moisture and protects the pasta, while the final uncovered bake gives the mozzarella its appealing melted and lightly browned finish.
If you are serving this meal for guests, assemble the dish earlier in the day, cover it, and refrigerate it until ready to bake. Allowing the chilled dish a little time on the counter before baking can help it warm more evenly, but always make sure the center is hot and the sauce is bubbling before serving.

Serving Ideas, Storage & Reheating
Serve two manicotti shells per person with extra marinara sauce spooned over the top. A green salad with a sharp vinaigrette cuts through the creamy filling, while garlic bread or crusty Italian bread is perfect for catching the sauce left on the plate.
Fresh herbs can be added just before serving if desired, although the recipe is complete as written. A small sprinkle of Parmesan at the table also adds a pleasant salty finish without changing the preparation.
- Refrigerating: Store cooled leftovers in a covered container or cover the baking dish tightly and refrigerate.
- Reheating: Reheat portions gently until hot throughout, adding a spoonful of sauce if the pasta looks dry.
- Serving leftovers: Let refrigerated manicotti sit briefly before reheating so the center warms more evenly.
Because the dish contains a creamy cheese filling, keep leftovers chilled and serve them while they are fresh and properly reheated. For a lighter side option, pair the manicotti with a simple salad rather than another rich casserole.

Easy Spinach Manicotti Recipe
Ingredients
Method
- Heat the oven to 375°F (190°C). Lightly grease a 9-by-13-inch baking dish and spread about 1 cup of marinara sauce over the bottom.
- Cook the manicotti shells in salted boiling water for about 6–7 minutes, or until just tender. Drain them carefully and let them cool slightly; do not overcook because they will continue cooking in the oven.
- In a large bowl, combine the ricotta, thoroughly squeezed spinach, egg, 1 cup of shredded mozzarella, Parmesan, Italian seasoning, garlic powder or minced garlic, salt, and black pepper. Stir until the mixture is evenly combined.
- Transfer the filling to a piping bag or a large zip-top bag with one corner snipped off. Fill each shell from both ends, or use a small spoon if preferred.
- Arrange the filled shells in the prepared baking dish. Spoon the remaining marinara sauce over the top and sprinkle with the remaining 1/2 cup mozzarella.
- Cover the dish tightly with foil and bake for 25 minutes. Remove the foil and continue baking for 10–15 minutes, until the sauce bubbles and the cheese melts and becomes lightly browned.
- Let the manicotti rest for 5 minutes before serving. This short rest helps the filling settle slightly, making the shells easier to serve.
Notes
Final Thoughts
This easy spinach manicotti recipe proves that a comforting baked pasta dinner does not need a long ingredient list or an elaborate cooking process. In about an hour, you can bring tender shells, creamy spinach-ricotta filling, marinara sauce, and golden mozzarella together in one bubbling dish.
Remember the three details that make the biggest difference: squeeze the spinach very dry, cook the shells only until just tender, and keep the dish covered until the final browning stage. After a five-minute rest, serve the manicotti with salad and warm bread for a meal that is inviting, filling, and delicious from the first forkful to the last.
