Ingredients

Pasta & Cheese Filling

  • 12 ounces jumbo pasta shells dry
  • 2 cups ricotta cheese
  • 4 ounces Parmesan cheese grated
  • 1 cup frozen chopped spinach thawed
  • 1 egg
  • 1/2 teaspoon salt or to taste
  • 1/2 teaspoon pepper or to taste

For Baking

  • 24 ounces marinara sauce 1 jar
  • 2 cups mozzarella cheese shredded
  • Fresh basil chopped (for garnish)

Instructions

  • Preheat the oven to 400°F.
  • Cook the jumbo shells in well-salted boiling water until al dente.
  • Stir frequently to prevent sticking, then rinse with cold water.
  • Squeeze excess water from the thawed spinach.
  • In a bowl, mix ricotta, Parmesan, spinach, egg, salt, and pepper.
  • Transfer the mixture to a piping bag or freezer bag.
  • Snip a 1-inch opening at the tip of the bag.
  • Pour half of the marinara sauce into a 9×13-inch casserole dish.
  • Pipe about 2 tablespoons of filling into each shell.
  • Arrange stuffed shells over the marinara in the dish.
  • Pour the remaining marinara on top.
  • Sprinkle with shredded mozzarella.
  • Bake for 20–25 minutes until bubbly.
  • Broil for 2–5 minutes to brown the cheese.
  • Garnish with fresh basil and cracked pepper.

Notes

Ingredient Substitutions

  • Use cottage cheese instead of ricotta for a lighter filling.
  • Swap spinach with sautéed kale or Swiss chard.
  • Add sautéed mushrooms or cooked sausage for extra flavor.

Make-Ahead & Storage

  • Assemble up to 24 hours ahead and refrigerate.
  • Freeze unbaked shells for up to 3 months.
  • Store leftovers in the fridge for 3–4 days.

Serving Variations

  • Serve with garlic bread and a fresh green salad.
  • Add crushed red pepper flakes for a spicy kick.
  • Use a creamy Alfredo sauce instead of marinara for a richer dish.

Avoid Common Mistakes

  • Don’t overcook the pasta—overcooked shells tear easily.
  • Make sure the spinach is well drained to avoid watery filling.
  • Don’t skip broiling—it creates the perfect cheesy top.
