Instructions
Preparation
Preheat the oven to 375°F (190°C).
Cook the jumbo shells in salted boiling water according to package instructions until al dente. Drain and let cool slightly.
In a large bowl, combine ricotta, cooked chopped spinach, half the mozzarella, Parmesan, egg, garlic powder, onion powder, salt, and pepper. Stir until smooth and evenly mixed.
Spoon the ricotta mixture into each shell (about 2 tablespoons per shell) and place the filled shells seam-side up in a single layer in a baking dish.
Pour marinara sauce evenly over the shells. Sprinkle the remaining mozzarella on top.
Baking
Cover the dish tightly with aluminum foil and bake for 25 minutes.
Remove the foil and bake an additional 10 minutes, until the cheese is bubbly and lightly golden.
Let cool for 5-10 minutes before serving.
Notes
For lighter version, use part-skim ricotta and low-moisture mozzarella. Add fresh herbs for brightness. To increase greens, use a mix of spinach and finely chopped kale or chard. Excess moisture in spinach can lead to watery filling.
