Spinach Stuffed Shells Ingredients
For the Shells
Jumbo Pasta Shells The sturdy architecture of this dish; choose high-quality shells to avoid breakage.
For the Filling
Frozen Chopped Spinach A nutritious and flavorful base; can be replaced with an equal amount of fresh spinach after cooking and draining.
Ricotta Cheese Adds creaminess and binds the filling; opt for cottage cheese as a lower-fat alternative, draining excess liquid first.
Shredded Mozzarella Cheese Essential for both filling and topping; a mix of Italian cheeses is a tasty alternative.
Grated Parmesan Cheese Brings a salty, nutty punch; nutritional yeast can mimic this flavor for a vegan twist.
Egg Acts as a binder for the filling; omit for vegan stuffed shells, but be mindful of cohesion.
Chopped Fresh Basil Infuses fresh, aromatic flavor; dried basil can be used, just halve the amount.
Salt Elevates overall taste; adjust according to your preference.
Garlic Powder Adds a subtle garlic taste; substitute fresh minced garlic for an extra kick (1 clove = 1.5 tsp).
For the Sauce
Marinara Sauce A flavorful moisture-rich base; feel free to use your favorite commercial brand or homemade for a personal touch.
These Spinach Stuffed Shells not only come together with these wholesome ingredients but also promise a delightful experience with each mouthful!
How to Make Spinach Stuffed Shells
Preheat your oven to 350 °F (175 °C) and spray a 9 x 13 inch baking dish with cooking spray, ensuring it s ready for those delicious stuffed shells!
Layer half of the marinara sauce evenly across the bottom of the prepared baking dish, creating a cozy base for your shells to nestle into.
Cook the jumbo pasta shells according to the package instructions until they re al dente; this usually takes about 8-10 minutes. Drain and let them cool under cold water to prevent sticking.
Squeeze the excess liquid from the thawed spinach and toss it into a large bowl. Add the ricotta, 1 ½ cups mozzarella, Parmesan, egg, chopped basil, salt, and garlic powder. Mix until everything is well combined and creamy!
Stuff each cooled shell with about 2 tablespoons of the spinach filling, arranging them open-side up in the baking dish. Take your time; these shells deserve some love!
Pour the remaining marinara sauce over the stuffed shells and sprinkle the remaining mozzarella on top, ensuring an irresistible cheesy crust!
Cover the dish with foil and bake for 30 minutes. For the last 5-10 minutes, remove the foil to let the cheese crisp up nicely, making it golden-brown and inviting.
Optional: Garnish with fresh basil leaves for an added pop of color and flavor.
