Spinach and Ricotta Stuffed Shell Recipe:
How to Make the Butternut Squash Sauce
Roast Vegetables:
1. Preheat your oven to 180°C.
2. Use a large bowl and toss cubed butternut squash, onion, and garlic in the olive oil mixture.
3. Place butternut squash mixture on a baking sheet. Season with salt and pepper.
4. Roast for 30-40 minutes or until soft and slightly caramelized.
Blend Sauce:
5. Combine the roasted vegetables, tomato paste, nutmeg, stock (or water), and cream in a blender. Blend until smooth. (Add more stock or water if needed)
6. Season with salt and pepper. Set aside.
Chef's Tips:
- Blend while warm for a smoother sauce.
- Work in batches if needed.
Cook the pasta shells:
7. Bring a large pot of water to a rolling boil. Generously season the water with salt.
8. Cook the jumbo shells in salted water until just under al dente, according to package directions. Drain and set aside.
How To Make Spinach and Ricotta Mixture
Sauté Spinach:
9. Heat olive oil over medium heat in a skillet. Sauté garlic until soft.
10. Add spinach and cook until wilted. Let cool.
Make Ricotta Filling:
11. In a mixing bowl, combine spinach, ricotta, mozzarella, Parmesan, and egg. Season.
Assemble and Bake:
12. Preheat the oven to 190°C (375 degrees F).

- Place your Stuffed Shells in a microwave-safe dish, making sure they're evenly arranged.
- Add a splash of water or add a spoonful of extra pasta sauce.
- Cover the container to lock in heat and prevent splattering.
- Start by microwaving them for a couple of minutes, keeping an eye on progress. This might take 2-3 minutes.
- If they're not fully reheated, continue in fifteen-second intervals until they reach the perfect temperature.
Air Fryer:
This method offers a unique twist to reheat your Stuffed Shells, providing a satisfyingly crispy finish.
- Preheat your air fryer to a gentle 95°C (200°F) for about 5 minutes.
- Place a sheet of foil in the fryer basket, creating a secure surface for your shells.
