Peel and chop the potatoes into roughly 1-inch cubes.
Place the potato cubes in a large pot and cover with cold water. Add 1 teaspoon of salt to the water.
Bring the water to a boil over medium-high heat, then reduce to a simmer. Cook the potatoes for 15-20 minutes or until fork-tender.
While the potatoes cook, preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch casserole dish.
Drain the cooked potatoes and return them to the pot. Add the butter, milk, sour cream, garlic powder, 1/2 teaspoon salt, and black pepper.
Mash the potatoes using a potato masher or electric mixer until smooth and creamy.
Stir in 1 1/2 cups of shredded Gouda cheese until evenly incorporated.
Transfer the mashed potato mixture to the prepared casserole dish and spread it evenly.
Sprinkle the remaining 1/2 cup of shredded Gouda cheese over the top.
Bake the casserole in the preheated oven for 20-25 minutes, or until the top is golden and bubbly.
Remove from the oven and let cool for 5 minutes. Garnish with chopped chives, if using, before serving.
