How to make it
- Heat the olive oil in a saucepan over medium heat, add the minced garlic and cook for about 1 minute until fragrant, then pour in the blended tomatoes and oregano, season with salt and pepper, and simmer for 20 minutes until thickened.
- Squeeze the thawed spinach hard to remove as much water as possible, then chop it roughly.
- In a bowl, beat the eggs, then mix in the ricotta, the spinach, half the parmesan, the nutmeg and a good pinch of salt and pepper to make the filling.
- Preheat the oven to 190 C (375 F) and spread a thin layer of tomato sauce over the base of a baking dish.
- Layer in lasagna sheets, then a third of the ricotta-spinach filling, a spoonful of sauce and a scatter of mozzarella, and repeat to build three layers, finishing with sheets topped with the remaining sauce, mozzarella and parmesan.
- Cover the dish tightly with foil and bake for 30 minutes, then remove the foil and bake for a further 15 to 20 minutes until bubbling and golden on top.
- Let the lasagna rest for 10 minutes so it sets before cutting into squares and serving.
