-If you don't have a
cast iron skillet (get one! haha) you can cook this in a casserole dish. Just cook the pancetta in a large skillet instead & spoon the mixture into a oven save 1½ quart casserole dish and bake as directed.
-I used a microplane to grate my parmesan cheese. It makes really fine cheese shavings. You can use whatever size grater you prefer.
