Description

This classic Italian Manicotti recipe features pasta shells stuffed with a creamy three-cheese and spinach filling, topped with marinara sauce and melted mozzarella cheese, then baked until bubbly and golden. It’s a comforting dinner favorite that is freezer friendly and perfect for family meals.


Ingredients

Pasta

  • 12 dried manicotti shells

Cheese Filling

  • 15 ounces ricotta cheese
  • 1 large egg
  • 1 cup frozen chopped spinach, thawed and squeezed dry
  • 1 cup shredded mozzarella cheese (from 2 1/2 cups divided)
  • 1/2 cup finely grated Parmesan cheese
  • 2 cloves garlic, minced
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon kosher salt
  • 1/8 teaspoon freshly ground black pepper
  • Dash of crushed red pepper flakes
  • Pinch ground nutmeg (optional)

Sauce and Topping

  • 25 oz jar marinara sauce, divided (can use homemade marinara)
  • 1 1/2 cups shredded mozzarella cheese (remaining from 2 1/2 cups)
  • 2 tablespoons freshly chopped basil, for garnish


Instructions

  1. Preheat Oven: Preheat your oven to 375 degrees F to prepare for baking the manicotti.
  2. Cook Pasta Shells: Bring a large pot of salted water to a boil. Add the manicotti shells and cook them for 2 minutes less than the package directions state, so that they are slightly undercooked and easy to fill. Avoid overcooking since they’ll finish baking in the oven.
  3. Drain and Cool Shells: Drain the cooked shells in a colander and rinse with cold water to stop the cooking. Lay the shells out in a single layer on a clean towel or cooling rack to prevent sticking.
  4. Prepare Filling: In a medium bowl, combine ricotta cheese, egg, thawed spinach (well drained), 1 cup mozzarella, Parmesan, minced garlic, Italian seasoning, kosher salt, black pepper, crushed red pepper flakes, and optional nutmeg until thoroughly mixed.
  5. Fill Shells: Using a piping bag or a gallon freezer bag with a corner snipped off, pipe the cheese mixture evenly into each manicotti shell carefully to avoid tearing.
  6. Assemble Baking Dish: Lightly grease a 9×13-inch baking dish. Spread 1 cup of marinara sauce evenly on the bottom. Arrange the filled manicotti in a single layer over the sauce.
  7. Add Sauce and Cheese Topping: Pour the remaining marinara sauce over the manicotti. Sprinkle the remaining 1 1/2 cups shredded mozzarella evenly across the top.
  8. Cover and Bake: Lightly grease a piece of foil to prevent sticking and cover the dish tightly. Bake in the preheated oven for 30 minutes until heated through.
  9. Uncover and Finish Baking: Remove the foil and continue baking for an additional 5 minutes to allow the cheese to bubble and melt fully.
  10. Broil for Golden Cheese: For a golden brown top, switch the oven to broil and bake for 1 to 2 minutes, watching carefully to prevent burning.
  11. Rest and Garnish: Remove from the oven and sprinkle with freshly chopped basil. Let the manicotti rest for 10 minutes before serving to set.

Notes

  • Usually, an 8 oz box of manicotti shells contains more than 12 shells; cook extra shells to account for any that break while boiling but only fill and bake 12.
  • Make sure to squeeze the frozen spinach thoroughly to avoid watery filling.
  • Using a piping bag makes filling the shells easier and less messy.
  • This dish can be made ahead and frozen before baking; increase baking time slightly when cooking from frozen.
