Ingredients

Scale

Shells and Cooking

  • Kosher salt
  • 1 (12-oz.) package jumbo shells
  • 1 tablespoon neutral oil

Vegetable & Filling

  • 1 medium yellow onion, finely chopped
  • 1 medium zucchini, chopped into 1/2″ pieces (about 2 cups)
  • 3 garlic cloves, finely chopped
  • Freshly ground black pepper
  • 2 cups ricotta cheese
  • 1/2 cup finely grated Parmesan cheese
  • 1 cup fresh or frozen corn kernels
  • 1/4 cup fresh basil leaves, finely chopped, plus whole leaves for serving
  • 1 1/2 cups shredded mozzarella cheese, divided
  • Zest and juice of 2 lemons, divided

Sauce

  • 3 cups store-bought or homemade marinara sauce

Instructions

  1. Preheat and cook shells: Arrange a rack in the center of the oven and preheat it to 350°F (175°C). Bring a large pot of salted water to a boil. Add the jumbo shells and cook, stirring occasionally, until al dente according to package instructions. Drain and set aside.
  2. Sauté vegetables: In a large skillet over medium heat, warm the neutral oil. Add the finely chopped onion and cook, stirring occasionally, until softened and translucent, about 7 minutes. Add the chopped zucchini and garlic, season with salt and freshly ground black pepper, and cook, stirring occasionally, until the zucchini is lightly browned and softened, about 5 to 7 minutes. Transfer the mixture to a large bowl and let it cool slightly.
  3. Prepare filling: To the cooled vegetable mixture, add the ricotta, finely grated Parmesan, corn kernels, chopped basil, 1/2 cup of shredded mozzarella, and the zest and juice from one lemon. Stir everything together until well combined. Season generously with salt and freshly ground black pepper to taste.
  4. Assemble shells: Spread the marinara sauce evenly on the bottom of a 13″ x 9″ baking dish. Stuff each jumbo shell with approximately 2 tablespoons of the ricotta and vegetable mixture, then neatly arrange the stuffed shells in the baking dish. Sprinkle the remaining 1 cup of shredded mozzarella cheese over the top.
  5. Bake: Bake the stuffed shells in the preheated oven until the cheese on top begins to brown and the sauce is bubbling, about 25 to 30 minutes.
  6. Garnish and serve: Once baked, top the shells with whole basil leaves and the zest of the remaining lemon. Cut the zested lemon into wedges and serve alongside. Let the dish sit for 5 minutes before serving to allow flavors to meld.

Notes

  • You can substitute frozen corn with fresh corn when in season for a sweeter flavor.
  • For a richer filling, add a bit more ricotta or a splash of cream.
  • Make sure not to overcook the pasta shells to avoid them breaking when stuffing.
  • Leftovers keep well refrigerated for up to 3 days and reheat nicely in the oven.
  • Use fresh basil for the best flavor; dried basil will not provide the same freshness.
