  • 5 lb Yukon Gold Potatoes peeled and cut into quarters
  • 1/2 tsp salt
  • 1 stick salted butter softened
  • 1/2 cup sour cream
  • 1/2 cup whole milk warmed in the microwave
  • 1/2 tsp garlic powder
  • 1/2 tsp ground white pepper
  • 1 1/2 tsp salt
  • chives finely chopped
  • 10 strips bacon cooked and crumbled
  • 2 cup cheddar cheese divided in half


  • In a large pot add quartered Yukon Gold Potatoes. Cover with cold water and place on the stovetop over medium-high heat. Add ½ tsp salt and stir into water. Bring water to a boil and let potatoes cook for 18-22 minutes (depending on the size of your cut potatoes). Potatoes are done when you can easily pierce with a fork.
  • Drain potatoes and place them in a large mixing bowl. Using a hand mixer with beaters, break the potatoes up in the bowl. Add 1 stick of softened butter, garlic powder, ground white pepper, and salt. Mix with a hand mixer for 30 seconds on high.
  • Add sour cream, warmed milk, and 1/2 of the cheddar cheese to the bowl. Beat on high until no lumps remain in potatoes.
  • Lightly grease a 9x13 baking dish and preheat the oven to 375 degrees F. Add potato mixture to the baking dish. Top with remaining cheddar cheese. Place in the oven and bake for 20 minutes, or until cheese is fully melted.
  • Sprinkle cooked bacon and chives on the top of the casserole. Serve and enjoy.
