How to Make Spinach and Ricotta Stuffed Shells

Step 1: Cook the Pasta Shells

Bring a large pot of salted water to a boil. Add the jumbo shells and cook them just until al dente, usually about 8 to 10 minutes. You don’t want them too soft, since they’ll finish cooking in the oven.

Once they’re cooked, drain the pasta and gently lay the shells out on a baking sheet or plate to cool slightly. This keeps them from sticking together and makes them easier to fill later.

Step 2: Prepare the Ricotta Filling

In a large mixing bowl, combine the ricotta cheese, half of the mozzarella, the Parmesan, and the egg. Stir until everything is evenly mixed and creamy.

In a skillet over medium heat, warm the olive oil. Add the minced garlic and sauté for about 30 seconds, just until it becomes fragrant. Add the chopped spinach and cook until wilted. This takes about 2 to 3 minutes if you’re using fresh spinach or 1 to 2 minutes if using frozen.

Let the spinach mixture cool for a minute or two, then fold it into the ricotta filling. Season everything with Italian seasoning, a pinch of salt, and some black pepper to taste.

Step 3: Preheat the Oven and Prepare the Baking Dish

Preheat your oven to 375°F, or 190°C. While it heats up, spread about one cup of marinara sauce across the bottom of a 9×13 inch baking dish. This layer helps prevent the shells from sticking and keeps the bottom moist.

Step 4: Stuff the Shells

Use a spoon or small spatula to fill each shell with about two tablespoons of the ricotta-spinach mixture. Don’t overfill them, just enough so that the shell closes comfortably around the filling.

Place the stuffed shells in the prepared baking dish with the open side facing up. Nestle them close together in a single layer.

Step 5: Add Sauce and Cheese

Spoon the remaining marinara sauce over the stuffed shells, making sure they’re nicely covered but not drowning in it. Sprinkle the remaining mozzarella cheese over the top for that perfect cheesy crust.

Step 6: Bake

Cover the dish with foil and bake for 20 minutes. Then, remove the foil and bake for another 10 minutes, or until the cheese is melted and starting to turn golden. You’ll see the sauce bubbling at the edges, and the smell will be irresistible.

Step 7: Let It Rest and Serve

Once the shells are out of the oven, let them sit for about five minutes before serving. This gives everything a chance to settle and makes it easier to scoop them out cleanly.

Garnish with fresh basil if you have some on hand, and serve hot. These are delicious with a simple salad or a side of garlic bread.

Helpful Tips

• Undercook the pasta slightly so it holds its shape while baking
• Use full-fat ricotta for a richer, creamier filling
• Don’t skip the resting step after baking, it helps the flavors come together
• You can prep this dish ahead of time and refrigerate it unbaked, just add a few extra minutes when baking
• Double the recipe and freeze half for a future dinner, it’s one of the easiest freezer meals to reheat

Storing and Reheating

Leftovers can be stored in an airtight container in the refrigerator for up to four days. Reheat individual portions in the microwave or warm the entire dish in a 350°F oven, covered with foil, until heated through.

If you want to freeze it, assemble the stuffed shells but don’t bake them. Cover the dish tightly with foil and freeze for up to two months. When you’re ready to eat, thaw it overnight in the fridge, then bake as directed.
