How to make Patate alla Pizzaiola

- Begin by peeling the potatoes, cover with salted water in a large sauce pan. Bring to a boil and cook until slightly underdone (about 25 minutes). That is, when you pierce the center of the potatoes with a sharp knife there is some resistence. Set aside and let cool slightly.

- While the potatoes boil, prepare a basic tomato sauce. Heat olive oil in a medium sized sauce pan, add garlic and let cook for 30 seconds. Pour in tomato passata, a little water and let simmer for 30 minutes. Add salt, to taste, and if you have, fresh basil leaves.

- Cut the mozzarella into cubes or shred it, if you prefer.

- When the potatoes are cool enough to handle, slice them into ¼ inch slices.

- Preheat oven to 350 degrees F. Lightly coat the bottom of a 9 x 13 casserole dish with the prepared tomato sauce (about 3 spoonfuls). Top with sliced potatoes to cover the bottom of the dish.

- Lightly season with salt, olive oil (about 1 tbsp.) and 1 teaspoon oregano. Then top with ½ of the cubed mozzarella and 1 tbsp. grated Parmigiano cheese.

- Top with ½ of the remaining tomato sauce.

- Continue with another layer of potatoes, salt, olive oil, oregano and grated cheese. This time top with the remaining tomato sauce before adding the rest of the mozzarella, and if you like, a little extra oregano on top.

- Bake for 30 minutes or until the cheese is completely melted and bubbling. Serve hot.

You'll notice that I lightly sauced my potatoes. This is personal preference as I don't like my potatoes drowning in sauce, however if you prefer you may double the amount of tomato sauce.
