Heat a cast iron skillet over low heat and add EVOO and crushed garlic, followed by a splash of water. Once the garlic bubbles, add the passata.
Add salt and pepper and cook the sauce on a low flame for at least 10 minutes (20 minutes at most) and set it aside.
Bring a large pot of water to a rolling boil and add 1 tablespoon of sea salt. Drop in the gnocchi and let it cook for a few minutes until it floats on the surface. Once cooked, collect the gnocchi with a strainer.
Put the sauce back on the stove, mix in the cooked ricotta gnocchi, and gently mix everything. Switch off the stove.
Cut Buffalo mozzarella into cubes and mix half of them into the sauce alongside pecorino cheese.
Add basil, stir it again, and top with the remaining Buffalo mozzarella.
Preheat the oven to 180 degrees C - 356 degrees F.
Put your cast iron skillet in the oven under the grill and bake for 5 to 8 minutes until the cheese melts with a nice crust on the top.
Serve on a plate, and enjoy!
