Spinach and Ricotta Stuffed Shells: Easy Baked Pasta Recipe

These spinach and ricotta stuffed shells bring together tender pasta, a creamy green-flecked filling, bright tomato sauce, and a bubbling mozzarella topping. Each shell holds its own little pocket of cheese and spinach, so the finished dish feels a little more special than an ordinary pasta bake without needing complicated ingredients. This Italian-inspired recipe works well for a relaxed family dinner or a weekend meal with friends. Most of the preparation is simple assembly: cook the shells, mix the filling, spoon it into the pasta, and let the oven finish the job. A generous layer of sauce keeps everything moist while the exposed edges turn lightly golden. Recipe at a Glance Servings: 6, about 4 stuffed shells each Preparation time: Approximately 30 minutes Baking time: 30 to 35 minutes Resting time: 5 minutes Total time: Approximately 65 to 70 minutes Equipment: Large pot, colander, mixing bowl, and a 9 x 13 inch (23 x 33 cm) baking dish Ingredients The quantities below make enough filling for about 24 jumbo shells. Cook a few extra shells because some can split in the pot. Pasta sizes vary, so choose large shells intended for stuffing rather than small soup shells. 28 jumbo pasta shells, to allow for a few broken pieces 425 g (15 oz) ricotta cheese, drained if watery 280 g (10 oz) frozen chopped spinach, thawed and squeezed very dry 200 g (7 oz) low-moisture mozzarella, shredded and divided 50 g (about 1/2 cup) finely grated Parmesan 2 garlic cloves, finely grated 1 teaspoon dried Italian herb seasoning 1/4 teaspoon ground black pepper 1/4 teaspoon fine salt, plus salt for the pasta water 720 ml (3 cups) marinara or tomato pasta sauce 1 teaspoon olive oil, for the baking dish A few fresh basil leaves, optional For a vegetarian version, check that the Parmesan or its substitute uses vegetarian rennet. The filling here is egg-free; draining the ricotta and spinach helps it hold together without an egg. How to Make Spinach and Ricotta Stuffed Shells 1. Prepare the Oven and Baking Dish Heat the oven to 190°C (375°F), or 170°C in a fan oven. Lightly oil the baking dish and spread 1 cup of tomato sauce across the bottom. This base layer helps prevent the pasta from sticking and gives the shells moisture as they bake. 2. Cook the Pasta Just Short of Done Bring a large pot of salted water to a boil. Add the shells and cook for about 2 minutes less than the package directions, stirring gently to separate them. They should bend enough to fill but still feel firm. Drain, briefly rinse with cool water to make them easier to handle, and arrange in a single layer on a tray. 3. Remove Moisture from the Spinach Place the thawed spinach in a clean kitchen towel and squeeze firmly over the sink. Loosen it, then squeeze again. This step makes a real difference: wet spinach thins the cheese filling and can leave a watery layer beneath the pasta. Break up any tightly packed clumps before mixing. 4. Mix the Ricotta Filling Filling Filling Combine the ricotta, spinach, 100 g of mozzarella, Parmesan, garlic, dried herbs, pepper, and salt in a bowl. Stir until evenly mixed. Taste and adjust the seasoning before filling the shells, keeping in mind that the tomato sauce and cheeses already contribute salt. The mixture should be thick enough to sit on a spoon. 5. Fill and Arrange the Shells Spoon the filling evenly into 24 intact shells, using approximately 2 tablespoons per shell depending on their size. Arrange them open-side up in the sauced dish. Keep them close together without forcing them into a tight stack. If a shell tears slightly, place its split side against a neighboring shell to support it. 6. Add Sauce and Bake Spoon the remaining 2 cups of sauce around and partly over the shells, leaving some filling visible. Scatter the remaining 100 g of mozzarella on top. Cover the dish with foil, tenting it slightly above the cheese. Bake for 20 minutes, then uncover and bake for another 10 to 15 minutes, until the sauce bubbles and the center is hot. 7. Rest and Serve Let the dish stand for 5 minutes before serving. This gives the filling a moment to settle and makes the shells easier to lift out neatly. Tear the basil leaves over the top, if using, and spoon some tomato sauce onto each plate before adding the pasta. Small Details That Improve the Result Choose a thick sauce. A watery tomato sauce can dilute the filling. If yours looks thin, simmer it separately until it coats a spoon, then measure the amount needed. A smooth marinara is convenient, while a chunky sauce gives the finished dish more texture. Use low-moisture mozzarella. It melts well without releasing as much liquid as fresh mozzarella. If fresh mozzarella is what you have, drain it thoroughly and pat it dry before tearing it into small pieces. Avoid overcooking the shells. Fully soft pasta is more likely to tear during filling and lose its shape in the oven. A slightly firm shell is easier to handle and finishes cooking in the sauce. Keep the filling balanced. The spinach should run through the ricotta in small pieces rather than large clumps. Chop it more finely if needed, especially when working with whole-leaf frozen spinach. Simple Variations To use fresh spinach, start with approximately 450 g (1 lb). Wilt it in a large pan, allow it to cool, then squeeze it dry and chop finely. Its final volume may differ slightly from frozen spinach, but the filling should remain mostly creamy ricotta with spinach distributed throughout. For a little heat, add a pinch of crushed red pepper to the sauce. For a brighter filling, mix in 1/2 teaspoon of finely grated lemon zest. If you want mushrooms, cook a small handful of finely chopped mushrooms until their moisture evaporates, let them cool, and add them without overcrowding the filling. What to Serve Alongside A crisp green salad with a simple lemon and olive oil dressing adds freshness beside the rich pasta. Roasted zucchini, broccoli, or green beans also work well. If you are serving bread, keep the portions modest and use it to scoop up the tomato sauce left on the plate. For a family-style meal, bring the baking dish to the table and serve the vegetables separately so everyone can build their own plate. Frequently Asked Questions Can I Use Cottage Cheese Instead of Ricotta? Yes. Drain it first, then blend briefly if you prefer a smoother texture. Cottage cheese can be saltier and wetter than ricotta, so adjust the seasoning after mixing and make sure the filling is not loose. What If I Cannot Find Jumbo Shells? Cannelloni can hold a similar filling, but follow the package instructions for preparation and baking. Do not assume that dry, oven-ready cannelloni will cook with the same timing or amount of sauce as these partly boiled shells. Why Are the Edges Dry? The shells may have been exposed to direct heat for too long or had too little sauce around them. Keep the dish covered for the first part of baking and spread sauce into the corners as well as the center.
