Ingredients
- Frozen Spinach: Frozen spinach is convenient to keep on hand and easy to thaw (see my tips below). If you want to use fresh spinach, you’ll need to first wilt the spinach in a skillet with a little olive oil over low heat. Then squeeze out all excess moisture before adding the spinach to the filling.
- Jumbo Pasta Shells: When cooking the shells, use the minimum cook time listed on the package. You don’t want to overcook the shells or they may fall apart.
- Ricotta Cheese: A classic stuffed shells ingredient.
- Cottage Cheese: Lightens up the cheese filling.
- Mozzarella Cheese: Melts wonderfully. You’ll use shredded mozzarella both in the stuffed shells filling and on top of the pasta bake.
- Parmesan Cheese: Grated Parmesan adds nutty, complex flavor.
- Italian Seasoning, Salt and Pepper: To season the cheese filling.
- Marinara Sauce: I usually use a jar of store-bought sauce to save time. If you prefer homemade, you’ll love this Marinara Sauce recipe.
To Thaw Frozen Spinach
- Refrigerator Method: Allow about 24 hours for the spinach to thaw in the refrigerator. Place the spinach in a bowl to catch any liquid.
- Microwave Method: Place frozen spinach in a bowl and thaw in 1-2 minute increments using the defrost setting of a microwave, stirring after each increment.
- Cold Water Method: Put the frozen spinach in a zip-top bag and defrost it under cold running water, or place it in a bowl of cold water (place a glass bowl on top to weigh it down), until thawed.
How to Make Stuffed Shells
Here is an overview of the steps to make this recipe. Find the full printable recipe with ingredient amounts below.
Cook the pasta shells in a pot of boiling, salted water. Then drain and place on a baking sheet to cool.
Squeeze out the spinach. Wrap it in a clean kitchen towel and squeeze out all excess liquid.
Make the spinach and cheese filling. In a mixing bowl, stir together the cheeses, Italian seasoning, salt, pepper and spinach.
Fill the pasta shells. Spread 1 cup of marinara sauce over the bottom of the baking dish. Spoon the filling into the shells and place in the baking dish.
Top with marinara sauce and mozzarella.
Bake until the shells are hot and the cheese is melted.
Then serve and enjoy! I like to serve these with Garlic Bread and an Italian Salad.
Make Ahead and Freezer Instructions
- To Freeze: Place the shells in a baking dish and top with the marinara sauce and mozzarella cheese. Once completely cool, cover the dish with a lid or wrap tightly with foil and freeze. The unbaked shells can be frozen for up to 2 months.
- To Refrigerate: You can prepare the shells in advance and refrigerate them in a covered baking dish for up to one day before baking. You may have to bake the shells for 5-10 additional minutes if they are cold from the refrigerator.
- To Bake Frozen Shells: To bake the shells frozen, directly from the freezer, add about 15-20 minutes to the covered bake time. Bake until the filling is hot and the sauce is bubbly. If you plan to freeze the shells, you may want to add some additional sauce on top to keep the shells from drying out during the longer bake time.
Stuffed Shells Recipe Variations
- To make stuffed shells with meat, cook 1 pound of ground beef or sausage in a skillet. Add half of the meat to the filling and the other half to the marinara sauce. You may want to reduce the amount of ricotta cheese and/or cottage cheese so that you don’t have too much filling.
- Not a fan of cottage cheese? You can substitute it with more ricotta cheese.
- If you don’t care for spinach you can leave it out of the recipe.
