Flavor notes and swaps

This version uses whole-milk ricotta for a creamy filling and mozzarella for that perfect pull. If you prefer a tangier filling, swap half the ricotta for a bit of shredded Parmesan or a small amount of shredded pecorino. For a meatier version, serve over a ragu or stir cooked ground beef or turkey into the sauce before arranging the shells. To keep things lighter, use part-skim ricotta and reduce the topping mozzarella, though whole-milk ricotta gives a richer texture.

Step-by-step instructions

The directions below follow the original order and ingredients exactly, rewritten into clear, step-by-step instructions. Read through once before starting so everything flows smoothly.

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish or a similar-sized casserole dish. Set it aside.
2. Bring a large pot of salted water to a rolling boil. Add the 12 jumbo pasta shells and cook them until they are just al dente—tender but still with a bit of bite—so they hold their shape when filled. This usually takes about 8–10 minutes, but check the package and taste a shell a minute or two early to avoid overcooking.
3. When the shells are al dente, drain them gently in a colander and rinse briefly under cool running water to stop the cooking. Place the shells on a clean kitchen towel or a baking sheet in a single layer so they don’t stick together while you prepare the filling.
4. In a medium mixing bowl, combine the 15 oz. whole-milk ricotta, 1 large egg, and ¾ cup shredded mozzarella. Add the 1 ½ cups roughly chopped fresh spinach, the ½ teaspoon Italian seasoning, 1 clove minced or grated garlic, ½ teaspoons salt, and ¼ teaspoon black pepper. Stir everything together until evenly mixed. The egg will help bind the filling and the spinach will wilt slightly into the cheese mixture.
5. Pour 1 jar of pasta sauce into the bottom of the prepared baking dish and spread it into an even layer. This creates a flavorful base so the shells bake in sauce rather than stick to the dish.
6. Using a spoon or small spatula, fill each cooled jumbo pasta shell with a generous scoop of the ricotta-spinach mixture. Aim to fill each shell fully so every bite has a creamy center. Place each filled shell, seam side up, into the sauce in the baking dish. Arrange them in a single layer so they bake evenly. If some filling remains, you can add a little to the sauce or save for another use.
7. Once all 12 shells are arranged in the dish, spoon any remaining sauce over the tops as needed so the shells are partly covered and won’t dry out during baking. Sprinkle the remaining ½ cup shredded mozzarella evenly over the shells for a melty, golden top.
8. Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes. This covered time allows the filling to heat through and the flavors to meld without over-browning the cheese.
9. After 20 minutes, remove the foil and bake uncovered for an additional 5–10 minutes, or until the cheese on top is fully melted and starting to brown slightly. Keep an eye on the oven during these last few minutes so the cheese reaches a golden, bubbly finish without burning.
10. Remove the baking dish from the oven and let the shells rest for about 5 minutes. This short rest helps the filling set slightly so the shells are easier to serve. Sprinkle chopped Italian parsley over the top for a fresh, herbaceous finish.
11. Serve the Stuffed Pasta Shells warm from the dish. They pair beautifully with a simple green salad and some crusty bread to mop up any extra sauce.

Storage and reheating

Leftovers keep well. Cover the baking dish tightly with plastic wrap or transfer shells to an airtight container and refrigerate for up to 3–4 days. To reheat, place portions in a microwave-safe dish and heat until warmed through, or reheat in a 350°F (175°C) oven until heated and bubbly, about 15–20 minutes. If the shells dry out while reheating, add a splash of extra pasta sauce or a tablespoon of water before warming.

Make-ahead tips

• Assemble the filled shells in the baking dish, cover tightly, and refrigerate for up to 24 hours before baking. When ready to bake, remove from fridge, add the topping mozzarella, and bake as directed—adding an extra 5 minutes to the covered baking time if the dish is cold.
• Freezing: Arrange the filled shells in a freezer-safe dish, cover tightly, and freeze. Bake from frozen at 375°F (190°C), covered, for about 40–50 minutes, then uncover and bake until the cheese melts and the dish is heated through.

Troubleshooting

• SHELLS STICK TOGETHER: Make sure shells are arranged in a single layer to cool, and rinse them briefly under cool water after draining to stop cooking and prevent sticking.
• FILLING TOO RUNNY: If your ricotta mixture seems watery, drain the ricotta in a fine sieve for a few minutes or press a clean kitchen towel gently around the filled shells to absorb excess moisture before baking.
• CHEESE NOT BROWNING: If you like a golden top, remove the foil for the last 5–10 minutes of baking or broil for 1–2 minutes while watching closely to avoid burning.
