How to Make Spinach and Ricotta Stuffed Shells

Preheat the oven to 375°F (190°C). This step is crucial to ensure that your shells bake evenly and come out bubbly and delicious.
Cook the jumbo pasta shells according to package directions until al dente. Drain them gently and set aside while you prepare the filling.
Sauté the onion in a large skillet with extra virgin olive oil over medium heat. Cook until the onion is tender and translucent, about 3-4 minutes, then add minced garlic for an additional minute.
Add the fresh spinach to the skillet and cook until it has wilted down, roughly 2 minutes. Transfer this mixture to a bowl where it will cool slightly.
Combine the spinach mixture with ricotta, both mozzarella and Parmesan cheeses, large egg, salt, and pepper. Mix everything until nicely blended, creating a rich filling.
Spread half of the marinara sauce evenly on the bottom of a baking dish. Carefully stuff each pasta shell with the cheese mixture and arrange them snugly in the dish. Pour the remaining sauce over the stuffed shells.
Bake the dish in the preheated oven for 20-30 minutes, or until the shells are heated through and the sauce is bubbling around the edges.
Serve hot, garnished with fresh basil and an extra sprinkle of Parmesan cheese if desired, to elevate the dish even more.

Optional: Drizzle some olive oil over the top for added richness before serving.

Expert Tips for Spinach and Ricotta Stuffed Shells

Drain Spinach Well: Excess moisture can lead to soggy shells. Make sure to squeeze out all water from frozen spinach before mixing.
Al Dente Pasta: Cooking the jumbo pasta shells until just firm ensures they hold up during baking without becoming mushy.
Egg Binding: Don’t skip the egg in the filling; it plays a crucial role in holding the cheese mixture together, ensuring a perfect stuffed shell every time.
Sauce Layering: Spread enough marinara sauce at the bottom of your baking dish. It not only prevents sticking but also adds moisture to the shells as they bake.
Make-Ahead Magic: These Spinach and Ricotta Stuffed Shells can be prepared up to two days in advance; just cover tightly in the fridge until you’re ready to bake.
