Pre-heat the oven on 200 C.
Use an oven dish to layer your ingredients. Start by a little tomato sauce on the bottom. Add some ricotta and mozzarella to it. Following by a layer of eggplants. Repeat the layering until all the sauce, ricotta and eggplants are used.
I like to end with a layer of eggplants, so you can see the beautiful eggplants slices on top.
Sprinkle parmesan cheese and mozzarella.
Bake for 20-30 minutes until golden brown and bubbly.
Garnish with basil.
