Preheat your oven to 375Β°F (190Β°C) and grease a 9x13-inch baking dish with butter or nonstick spray.
Peel the potatoes and cut them into 1-inch cubes. Rinse them under cold water to remove excess starch.
Place the potato cubes in a large pot, cover with water, and add 1 teaspoon of salt. Bring to a boil over medium-high heat, then reduce to a simmer and cook for 12-15 minutes, or until the potatoes are fork-tender.
Drain the potatoes well and return them to the pot. Mash the potatoes until smooth using a potato masher or hand mixer.
Stir in the sour cream, 1.5 cups of shredded cheddar cheese, butter, milk, remaining 0.5 teaspoon of salt, black pepper, and garlic powder. Mix until everything is combined and creamy.
Transfer the potato mixture to the prepared baking dish and smooth the top evenly.
If using, combine the panko breadcrumbs and Parmesan cheese in a small bowl and sprinkle the mixture over the top of the potatoes.
Bake in the preheated oven for 25-30 minutes, or until the casserole is heated through and the top is golden and bubbly.
Remove the casserole from the oven and let it rest for 5 minutes. Garnish with chopped green onions, if desired, before serving.
Serve warm and enjoy this rich and flavorful dish!
