Ingredients

  • 7 russet potatoes large, peeled and quartered
  • 8 Tablespoons cream cheese at room temperature
  • ½ Cup sour cream
  • ¼ Cup milk
  • 2 Tablespoons butter at room temperature
  • 1 Teaspoon garlic powder
  • ½ Teaspoon salt
  • ½ Teaspoon black pepper
  • ¾ Cup sharp cheddar cheese shredded
  • 8 Slices bacon cooked and chopped
  • green onions chopped for optional garnish

Instructions

  • Preheat the oven to 350°F and spray a 9 x 13-inch baking dish with nonstick cooking spray. Set aside.
  • Add potatoes to a large pot and fill with cold water. Bring to a boil and cook for 15 to 20 minutes or until you can easily pierce a potato using a fork.
  • Drain and transfer them back into the pot.
  • Add the cream cheese, sour cream, milk, butter, garlic powder, salt, and pepper to the potatoes, and mash until smooth and fluffy.
  • Add the potato mixture to prepared baking dish. Top with cheddar cheese and bacon.
  • Cover and bake for 10 minutes. Uncover and cook for an additional 10 to 15 minutes, or until the cheese is melted.
  • Garnish with chopped green onions before serving, if liked.

Notes

Crispy bacon: For the best texture, cook the bacon until it's extra crispy before adding it to the casserole. The crunch contrasts perfectly with the creamy potatoes.
Don’t overmix: Once you’ve added the cream cheese, sour cream, and other ingredients, avoid overmixing. Overworking or over-mashing the potatoes can make them gluey instead of light and fluffy.
Prep ahead: You can assemble the loaded mashed potatoes in advance and bake them when ready to eat.
Check seasoning: You must add enough salt and pepper to get the best flavor possible. Add a little chicken broth to the potato cooking water for extra flavor.
Freshly grate cheese for best results: I recommend using a cheese grater and grating the cheddar cheese from the block instead of buying pre-packaged shredded cheese. It will melt easier and isn’t filled with preservatives and anti-caking agents.
