This dish is as visually appealing as it is delicious—the large pasta shells act as little vessels for a flavorful and creamy stuffing, nestled in a vibrant red marinara sauce and topped with melted cheese.

How to Serve

Recipe Tips

• Use fresh spinach for the best flavor; if using frozen, ensure it is fully thawed and squeezed dry.
• Don’t overcook the pasta shells—they will continue cooking in the oven.
• Assemble ahead of time: Stuff shells and refrigerate for up to 24 hours before baking.
• For extra flavor, add sautéed mushrooms, roasted red peppers, or zucchini to the filling.

Variations

1. Meat Option: Add cooked ground beef, sausage, or turkey to the ricotta filling.
2. Cheese Variations: Use goat cheese or feta for a tangy twist.
3. Spicy Variation: Add crushed red pepper flakes to the filling or sauce.
