cheesy potato soup with ham

i made this soup last month, when we had an abnormally rainy and cold day smack in the middle of the summer. now that fall has shown up with rain and cooler temperatures, it's a great time to bring soup back in the regular rotation. this soup is rich and creamy from the potatoes and cheese and perfectly salty with the ham. if you want a meatless meal, simply omit the ham. the only thing i will do differently next time: top with crispy bacon.
