Ingredients

  • 1 12-ounce box jumbo pasta shells
  • 1 tablespoon olive oil
  • 2 shallots finely minced
  • 2 cloves garlic minced
  • 1 16-ounce package frozen chopped spinach, thawed and thoroughly squeezed dry
  • 16 ounces whole milk ricotta cheese
  • 1 large egg
  • ¾ cup grated Parmesan cheese divided
  • 2 tablespoons fresh parsley finely chopped
  • ¼ teaspoon freshly grated nutmeg
  • 1 teaspoon kosher salt
  • ½ teaspoon freshly ground black pepper
  • 1 23- to 24-ounce jar marinara sauce, plus extra if desired
  • 1 8-ounce ball fresh mozzarella, grated
  • Fresh basil leaves for serving

Instructions

  • Preheat the oven to 375°F (190°C).

Boil the pasta

  • Bring a large pot of generously salted water to a boil. Cook the pasta shells until just al dente according to package directions. Drain and toss lightly with a drizzle of olive oil to prevent sticking.

Make the ricotta stuffing

  • While the pasta cooks, heat the olive oil in a small skillet over medium heat. Add the shallots and cook until softened, about 3 minutes. Add the garlic and cook for another 30 seconds, until fragrant. Remove from the heat.
  • In a large mixing bowl, combine the spinach, ricotta, egg, ½ cup of the Parmesan cheese, parsley, nutmeg, salt, pepper, and the shallot-garlic mixture. Stir until well combined.

Assemble

  • Spread about 1 cup of marinara sauce over the bottom of a 9 x 13-inch baking dish.
  • Fill each shell generously with the ricotta mixture and arrange them snugly in the baking dish.
  • Spoon the remaining marinara sauce evenly over the shells.

Bake

  • Cover the dish tightly with foil and bake for 25 minutes.
  • Remove the foil and sprinkle the shells with the grated mozzarella and the remaining ¼ cup Parmesan cheese.
  • Return to the oven and bake uncovered for 10 to 15 minutes, until the cheese is melted and lightly golden.

Serve

  • Let the shells rest for 5 minutes before serving.
  • Garnish with fresh basil and additional Parmesan, if desired.

Notes

For the best texture, be sure to squeeze as much moisture as possible from the thawed spinach before mixing the filling.
These stuffed shells can be assembled up to a day in advance and refrigerated until ready to bake. If baking from cold, add 5–10 minutes to the covered baking time.
