Ingredients

Scale

Main Ingredients:

  • 1 box (12 ounces / 340 grams) jumbo pasta shells
  • 1 container (15 ounces / 425 grams) ricotta cheese
  • 1 1/2 cups shredded mozzarella cheese
  • 2 cups fresh spinach (chopped)
  • 1 jar (24 ounces / 680 grams) marinara sauce

Cheese and Dairy:

  • 1/2 cup grated Parmesan cheese
  • 1 large egg

Herbs and Seasonings:

  • 2 cloves garlic (minced)
  • 1 tablespoon fresh basil (chopped)
  • 1 tablespoon fresh parsley (chopped)
  • Salt and pepper to taste
  • 1/2 cup water

Instructions

  1. Gently boil jumbo pasta shells in salted water until just tender, approximately 8-9 minutes. Drain and allow to cool slightly, preventing overcooking.
  2. Create a creamy filling by whisking ricotta, mozzarella, Parmesan, egg, chopped spinach, garlic, basil, parsley, salt, and pepper until smooth and well-integrated.
  3. Generously stuff each shell with the prepared mixture, ensuring even distribution and avoiding overfilling.
  4. Prepare the slow cooker by spreading a thin layer of marinara sauce across the bottom to prevent sticking and potential burning.
  5. Arrange stuffed shells carefully in a single layer, slightly overlapping if necessary to maximize space within the slow cooker.
  6. Pour remaining marinara sauce over shells, then rinse sauce jar with water and drizzle liquid to ensure complete shell coverage and moisture.
  7. Set slow cooker to low temperature and cook for 3-4 hours, maintaining consistent heat around 200°F until shells become tender and filling is heated thoroughly.
  8. During final 15 minutes of cooking, sprinkle additional mozzarella across the top, allowing cheese to melt and create a golden, bubbling surface.
  9. Delicately transfer shells to serving dish using a large slotted spoon, preserving structural integrity. Garnish with fresh herbs and serve immediately while warm.

Notes

  • Lightly coat shells with olive oil after cooking to stop them from clumping together during cooling and stuffing.
  • Squeeze excess moisture from chopped spinach using a clean kitchen towel to avoid watery filling and maintain shell structure.
  • Replace ricotta with cottage cheese for a lower-fat alternative that still provides creamy texture and protein.
  • Use gluten-free jumbo pasta shells and verify marinara sauce ingredients to make this recipe celiac-friendly.
