Ingredients:
- 12 oz (340g) Jumbo Pasta Shells
- Salt (for pasta water)
- 2 tablespoons Olive Oil (30ml)
- 1 small Yellow Onion, finely chopped
- 3 cloves Garlic, minced
- 32 oz (900g) Whole Milk Ricotta Cheese
- 10 oz (280g) Frozen Chopped Spinach, thawed and squeezed dry
- 2 cups (approx. 225g) Shredded Mozzarella Cheese, divided
- 1 cup (approx. 100g) Grated Parmesan Cheese, divided
- 1 Large Egg, lightly beaten
- 1 teaspoon Italian Seasoning
- 1 teaspoon Salt
- ½ teaspoon Black Pepper, freshly ground
- 24-32 oz (680-900g) High-Quality Marinara Sauce (about 3-4 cups)
- Fresh Basil or Parsley, chopped (optional)
Instructions:
- Bring a large pot of heavily salted water to a rolling boil. Add pasta shells and cook according to package directions but undercook slightly (al dente). Drain and rinse with cool water; spread on a baking sheet to cool.
- Thaw frozen spinach completely. Squeeze all excess water from the spinach using cheesecloth or a kitchen towel.
- Heat olive oil in a skillet over medium heat. Sauté onion until translucent. Add garlic and cook until fragrant (avoid burning). Remove from heat and let cool slightly.
- In a large bowl, combine ricotta, 1 cup mozzarella, ½ cup Parmesan, and egg. Add squeezed spinach, sautéed onion/garlic, Italian seasoning, salt, and pepper. Mix well. Taste and adjust seasoning if needed.
- Preheat oven to 375°F (190°C). Spread 1-1.5 cups marinara sauce in the bottom of the baking dish. Stuff each shell with the ricotta mixture. Arrange stuffed shells in the baking dish, open-side up. Pour remaining marinara sauce over the shells. Sprinkle remaining mozzarella and Parmesan cheese on top. Cover tightly with aluminum foil. Bake for 25 minutes.
- Remove foil. Bake for another 10-15 minutes, or until cheese is melted, bubbly, and golden brown. Let rest for 10-15 minutes before serving. Garnish with fresh basil or parsley (optional).
