1 teaspoon salt

½ teaspoon black pepper

½ teaspoon garlic powder

1 ½ cups shredded cheddar cheese

2. Drain and return potatoes to the pot or a mixing bowl.

3. Add butter, cream cheese, sour cream, milk, garlic powder, salt, and pepper. Mash or beat until smooth.

Add a layer of caramelized onions or sautéed garlic for an extra flavor boost.
