ingredients

  • 8 ounces large pasta shells
  • 15 ounces ricotta cheese
  • 1 1/2 cups shredded skim-milk mozzarella cheese, divided
  • 3/4 cup fresh grated parmesan cheese, divided (plus extra for serving)
  • 1 large egg
  • 2 tablespoons olive oil
  • 3 garlic cloves, minced
  • 5 cups chopped fresh baby spinach
  • 1/4 cup chopped fresh basil
  • 1 teaspoon kosher salt
  • 1/2 teaspoon freshly ground black pepper
  • 1 (24 ounce) jar Muir Glen Classic Marinara Sauce

Method

  • Step 1

    Preheat the oven to 350°F.

  • Step 2

    Cook the pasta shells according to the package directions until al dente. Drain, rinse with cool water, and set aside.

  • Step 3

    Heat olive oil in a large skillet over medium-high heat. Add minced garlic and cook until fragrant, about 1 minute.

  • Step 4

    Add baby spinach and sauté until wilted, about 3-5 minutes. Remove from heat and let cool slightly.

  • Step 5

    In a large mixing bowl, combine ricotta cheese, 1 cup mozzarella, and ½ cup parmesan cheese with the egg. Stir until smooth.

  • Step 6

    Add chopped basil, kosher salt, and black pepper. Fold in the cooked spinach and garlic. Transfer the mixture to a piping bag (or use a zip-top bag with a corner cut).

  • Step 7

    Spread half of the marinara sauce in the bottom of a 2.5-quart baking dish.

  • Step 8

    Pipe the cheese filling into each cooked pasta shell and arrange them in a single layer over the sauce.

  • Step 9

    Spoon the remaining marinara sauce over the stuffed shells, filling in any gaps. Sprinkle with the remaining ½ cup mozzarella cheese.

  • Step 10

    Cover the baking dish with aluminum foil and bake on the middle rack for 25 minutes.

  • Step 11

    Remove the foil and bake for an additional 15-20 minutes, until the sauce bubbles and the cheese is melted.

  • Step 12

    Remove from the oven and sprinkle with the remaining ¼ cup parmesan cheese. Let the dish rest for 5 minutes before serving.
