Preparing the Filling and Pasta
The most important step in this recipe is handling the spinach correctly. After thawing it completely, place the greens in a clean kitchen towel and wring out as much water as physically possible. If you skip this step, the excess water will pool at the bottom of your baking dish, resulting in a watery, bland sauce. The greens should feel dry to the touch before mixing.
In a large bowl, combine the dry spinach, ricotta cheese, one cup of the mozzarella, the Parmesan, egg, minced garlic, Italian seasoning, salt, and pepper. Stir the mixture vigorously until it is completely uniform. Meanwhile, boil the jumbo shells in a large pot of heavily salted water. You want to cook them for two minutes less than the package instructions indicate. They should still be slightly tough, as they will finish cooking in the oven. Drain the shells and lay them flat on a baking sheet to cool slightly so they do not stick together.
Assembling and Baking Your Shells
To begin assembly, spread one cup of marinara sauce evenly across the bottom of a 9×13 inch baking dish. This prevents the pasta from sticking and burning. Using a standard spoon or a piping bag, generously fill each cooled shell with the ricotta mixture and place them open-side up in the baking dish. They should fit snugly together.
Once all the shells are arranged, pour the remaining marinara sauce directly over the top of the pasta, ensuring the edges are coated so they do not dry out in the oven. Sprinkle the remaining cup of shredded mozzarella evenly over the dish. Bake covered with aluminum foil at 375 degrees Fahrenheit for 25 minutes. Remove the foil and bake for an additional 10 minutes until the cheese on top is bubbling and lightly golden brown.
Ingredient Variations and Creative Additions
If you are searching for dinner ideas no chicken involved but want to alter the flavor profile slightly, this recipe is incredibly adaptable. For those looking at health easy dinner recipes, you can mix half a cup of finely diced, sautéed zucchini or mushrooms directly into the cheese filling to increase the vegetable volume.
While this is traditionally a pasta dish, if you need no pasta dinner ideas for a low-carb diet, you can use this exact same spinach and ricotta filling to stuff large, hollowed-out portobello mushroom caps or halved bell peppers instead. Simply adjust the baking time depending on the vegetable base you choose.
FAQ
Can I use fresh spinach instead of frozen?

Can I prep this meal ahead of time?

Why did my shells tear while boiling?

Can I freeze the leftovers?
Yes, baked shells freeze wonderfully. Let the dish cool completely, then store individual portions in airtight containers in the freezer for up to three months. Reheat them in the microwave or oven.
What can I serve with this dish?
A crisp green salad with a bright vinaigrette helps cut through the heavy richness of the cheese. A slice of warm, crusty garlic bread is also perfect for soaking up any leftover marinara sauce.
