Detailed Directions and Instructions
Prepare the Sauce:
1. Heat olive oil in a small pot over medium-high heat. Add the finely chopped eschalots (or onion), minced garlic, bay leaf, dried thyme, and dried oregano. Sauté for 3–4 minutes until the onion becomes translucent.
2. Stir in the tomato paste and cook for 1 minute to remove its raw taste.
3. Pour in the dry white wine, increase the heat to high, and let it simmer rapidly until mostly evaporated, about 2 minutes.
4. Add the tomato passata, vegetable stock, white sugar, salt, and black pepper. Stir to combine, then reduce the heat to low and let it simmer uncovered for 20 minutes. Keep the sauce hot for assembly.
Prepare the Filling:
1. In a bowl, combine the thawed and drained spinach, ricotta cheese, shredded Parmesan, shredded cheese, beaten egg, minced garlic, nutmeg (if using), kosher salt, and black pepper. Mix thoroughly until well combined.
Assemble and Bake:
1. Preheat the oven to 200°C (400°F) or 180°C (350°F) if using a fan-forced oven.
2. Stuff each uncooked jumbo pasta shell generously with the spinach and ricotta filling.
3. Pour the hot tomato sauce into a 23 x 33 cm (9 x 13 inch) baking dish. Gently place the stuffed shells into the sauce, ensuring most are submerged; it’s okay if some parts are above the surface.
4. Cover the baking dish with a baking tray or foil and bake for 70 minutes.
5. After 70 minutes, remove the cover, sprinkle the shredded mozzarella and Parmesan cheeses over the shells, and return to the oven. Bake uncovered for an additional 15 minutes until the cheese is melted and bubbly.
6. Once baked, garnish with fresh basil and additional Parmesan cheese if desired. Serve warm.
Notes
Storage:
Leftover stuffed shells can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave.
Freezing:
These stuffed shells can be frozen before baking. Arrange them in a baking dish without sauce, cover tightly, and freeze. When ready to bake, thaw overnight in the refrigerator, then top with the sauce and bake as instructed.
Variations:

Serving Suggestions:
Serve with a side salad and crusty bread for a complete meal.

Cook techniques
Sautéing
Sautéing involves cooking food quickly in a small amount of oil over relatively high heat. In this recipe, eschalots or onion and garlic are sautéed until translucent to develop their flavors before adding other ingredients.
Simmering
Simmering is a cooking technique involving cooking food gently in liquid just below its boiling point. The sauce is simmered to allow the flavors to meld together and thicken slightly.
Mixing
Mixing involves combining ingredients thoroughly to ensure a uniform consistency. In the filling preparation, various cheeses, spinach, and seasonings are mixed together to create a rich stuffing.
Stuffing
Stuffing refers to filling a food item with a mixture. In this recipe, uncooked jumbo pasta shells are generously filled with the spinach and ricotta mixture, ensuring a hearty and flavorful bite.
Baking
Baking is a dry heat cooking method where food is cooked in an oven. The stuffed shells are baked first covered to cook through and then uncovered to brown the cheese, creating a deliciously melted top.
