Boil the potato chunks in a pot of salted water until they are fork-tender, which should take about 15 minutes. Once done, drain the potatoes and let them cool.
In a large mixing bowl, combine the cooled potatoes with the chopped bacon, shredded cheese, sour cream, mayonnaise, sliced green onions, and chopped parsley. Season with salt and pepper to your liking and stir everything together until well mixed.
Cover the bowl and refrigerate the potato salad until it’s chilled and ready to serve. This will allow the flavors to meld together beautifully.
