Preheat your oven to 375°F (190°C).
Peel the russet potatoes and chop them into small, evenly-sized cubes, about 1 inch in size.
Place the potato cubes in a large pot, cover them with water, and bring to a boil over medium-high heat. Cook for 10–15 minutes, or until the potatoes are tender and easily pierced with a fork.
While the potatoes are boiling, heat a skillet over medium heat and lightly spray it with non-stick cooking spray. Add the diced onion and sauté until soft and translucent, about 3–4 minutes. Remove from heat and set aside.
Drain the cooked potatoes thoroughly and return them to the pot. Mash them lightly with a potato masher, leaving some texture for a rustic casserole.
Add the low-fat sour cream, 1 cup of shredded cheddar cheese (reserve the remaining 0.5 cup for topping), chicken or vegetable broth, sautéed onions, garlic powder, salt, and pepper to the mashed potatoes. Stir until the mixture is well combined and creamy.
Lightly grease a 9x13-inch baking dish with non-stick cooking spray. Spread the potato mixture evenly in the dish.
Sprinkle the reserved 0.5 cup of shredded cheddar cheese evenly on top of the casserole.
Bake in the preheated oven for 25–30 minutes, or until the cheese on top is melted and slightly golden.
Remove from the oven and let the casserole rest for 5 minutes before serving. Garnish with chopped chives or green onions if desired.
