Ingredients

Scale

Pasta

  • 12 ounces jumbo pasta shells (about 2024 shells)

Filling

  • 1 pound ground beef
  • 1/2 cup onion, diced
  • 4 cloves garlic, minced
  • 2 cups loosely packed fresh spinach
  • 1 teaspoon basil
  • 1 teaspoon garlic powder
  • 1 teaspoon oregano
  • Salt and pepper, to taste

Sauce & Cheese

  • 2 cups marinara sauce
  • 1 cup shredded mozzarella cheese
  • 1/2 cup shredded Parmesan cheese

Instructions

  1. Preheat and Cook Pasta: Preheat your oven to 400°F (200°C). Bring 6 cups of salted water to a boil in a large pot and cook the jumbo pasta shells according to package instructions until al dente. Avoid overcooking since the shells will finish cooking in the oven.
  2. Prepare the Filling: While the pasta cooks, heat a large skillet over medium heat. Add the ground beef, diced onion, and minced garlic. Cook for 3 to 4 minutes, stirring occasionally, until the beef is fully browned and onions are softened. Add fresh spinach, basil, garlic powder, oregano, salt, and pepper. Cook for an additional 2 minutes until the spinach wilts. Stir in half of the marinara sauce to blend the flavors.
  3. Assemble the Shells: Drain the cooked pasta shells and arrange them in a 13×9-inch (or similar size) oven-safe casserole dish. Carefully fill each shell with 2 to 3 tablespoons of the beef and spinach mixture.
  4. Add Sauce and Cheese: Pour the remaining marinara sauce evenly over the stuffed shells. Sprinkle shredded mozzarella and Parmesan cheese over the top.
  5. Bake: Cover the casserole dish with aluminum foil and bake in the preheated oven for 15 minutes. Then remove the foil and broil for 1 to 2 minutes until the cheese is golden and bubbly, watching carefully to prevent burning.
  6. Serve: Remove from the oven and let the stuffed shells cool slightly before serving. Garnish with extra Parmesan or fresh basil if desired and enjoy warm.

Notes

  • Be careful not to overcook the pasta shells during boiling as they will finish cooking while baking.
  • Use fresh spinach for best texture and flavor; frozen spinach can be substituted but drain thoroughly before adding.
  • Broil at the end to get a nicely browned cheese crust, but watch closely as it can burn quickly.
  • Feel free to add red pepper flakes to the filling if you prefer a slight kick.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven.
