Equipment

  • 1 9" x 13" baking dish or casserole dish

Ingredients
  

  • 4 pounds russet potatoes (choose small to medium potatoes)
  • 6 tablespoon salted butter
  • ½ cup sour cream
  • 8 oz. sharp cheddar cheese (shredded, divided)
  • 6 slices cooked bacon (chopped, divided)
  • 1 cup 2% milk
  • 1 teaspoon kosher salt
  • ½ teaspoon ground black pepper
  • 2 tablespoon chives (finely diced)

Instructions
 

  • Preheat the oven to 400°F.
  • Wash the potatoes and pierce them with a fork several times each. Roast them on the oven rack for 1 hour.
  • Remove the potatoes from the oven and allow them to cool for 5 minutes, or until you can handle them safely.
  • Slice the potatoes in half lengthwise and scoop out the potato into a large bowl.
  • Add the butter, sour cream, 5 ounces of the cheese, 4 slices of bacon, milk, salt, and pepper. Use a potato masher to mash all of the ingredients together until well combined.
  • Grease your casserole pan and add the potato mixture, spreading it out to an even layer. Sprinkle the reserved bacon and cheese over the top.
  • Bake the potatoes for 15-20 minutes, until the cheese is melted. Remove the casserole from the oven and sprinkle with the chives before serving.
