Preheat your oven to 375 degrees Fahrenheit. This is an important step, ensuring that the Spinach Stuffed Shells bake evenly and thoroughly. While the oven heats, prepare your baking dish by spraying a 9X13 baking dish with cooking spray. This will prevent the shells from sticking.
Next, cook the jumbo pasta shells according to the package directions. This usually takes about 10 to 12 minutes. Once cooked, drain them and set them aside to cool slightly. Be sure to avoid overcooking; you want them al dente since they will bake further in the oven.
In a skillet over medium-high heat, add 1 tablespoon of water and the spinach. Cook until the spinach has wilted and the water has evaporated, which should take about 3 to 4 minutes. The bright green color will be a telltale sign that it’s ready to be used.
In a medium bowl, whisk together the ricotta cheese, parmesan cheese, garlic, Italian seasoning, salt, and pepper. Ensure everything is well combined. The mixture should be creamy and flavorful, with a hint of garlic that will permeate the entire dish.
Now, stir in the cooked spinach until it’s evenly distributed throughout the cheese mixture. This vibrant filling is what makes Spinach Stuffed Shells so special.
Pour 1 cup of the marinara sauce into the prepared baking dish, spreading it out evenly. This layer of sauce not only adds flavor but also keeps the shells moist while baking.
Using a spoon, stuff each shell with about 1 tablespoon of the ricotta filling and arrange them in a single layer in the pan, filling side up. It’s okay if they’re snug; the sauce will help them cook perfectly.
Once all the shells are filled, pour the remaining marinara sauce over the shells, ensuring they are well coated. This is crucial for flavor and moisture.
Sprinkle the shredded mozzarella cheese over the top of the shells. The more, the merrier! This will give you a deliciously cheesy crust once baked.
Bake for about 25 to 30 minutes, or until the cheese is bubbling and golden brown. Keep an eye on it—your kitchen will smell heavenly as it cooks!
