This varies depending on your personal preference, but I recommend frying a country ham slice for 2.5 minutes on each side as a minimum. This of course depends on the heat output of your own stovetop. Once it’s brown on the outside, it’s ready to serve. You can fry your country ham for a little longer if you wish. For a really crispy finish, consider frying each side for 4 minutes instead. Don’t fry it for any longer than that, and keep a mental note of how long you cooked it for so you can adjust the timings to suit your taste better next time.
