Place the potatoes in a large pot and cover with cold water by 1 inch. Add kosher salt, bring to a simmer, and cook until a knife slides in easily, about 15-20 minutes.
02 -
Drain the potatoes and let them cool just until you can handle them. Slice into 1/2-inch coins or chunky bite-size pieces and place in a warm mixing bowl.
03 -
Cook the diced bacon in a large skillet over medium heat until browned and crisp, about 7-9 minutes. Transfer the bacon to a plate and leave about 3 tablespoons drippings in the skillet.
04 -
Add the onion to the skillet and cook in the bacon drippings until translucent, about 3 minutes. Stir often and keep it from browning too deeply.
05 -
Stir in the chicken broth, apple cider vinegar, mustard, sugar, salt, and pepper. Simmer for 2-3 minutes, scraping up the browned bits from the skillet.
06 -
Pour the hot dressing over the warm potatoes. Add the bacon, parsley, and chives, then fold gently until coated. Rest 10 minutes before serving warm or at room temperature.
