Assembly
In a medium bowl, add the creamy ricotta cheese.
Add the egg, the grated mozzarella cheese, the grated parmesan cheese, parsley to taste, a pinch of salt, a pinch of black pepper, mix everything very well until combined and set aside.
In a large baking dish, add the tomato sauce and spread very well.
To start assembling the lasagna, add the basil-mozzarella ravioli covering the entire sauce.
Add the creamy ricotta mixture we prepared earlier and spread it evenly.
Then, add the grated mozzarella cheese and for the next layer, add the ricotta-spinach ravioli.
Cover with another 50g of tomato sauce and add fresh basil leaves to taste.
Cover with another 100g of mozzarella cheese and make another layer with the basil-mozzarella ravioli.
Now, cover with another 50g of tomato sauce, finish by making a last layer with another 100g of grated mozzarella cheese and 50g of grated Parmesan cheese.
Wrap the baking dish in aluminum foil, take it to a preheated oven at 200° C (400° F) and bake for 35 minutes.
After this time has passed, remove the aluminum foil and let it all bake until the cheese is completely melted and browned.
Serve.
