Equipment

  • 1 9x13 casserole dish

Ingredients

  • 5 pounds russet potatoes peeled and cut into chunks
  • 8 tablespoons butter softened
  • 1 cup sour cream
  • 8 ounces cream cheese softened
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon kosher salt
  • ½ teaspoon black pepper
  • 2 cups shredded sharp cheddar cheese divided

Instructions
