1 (30 ounce) package frozen shredded hash brown potatoes, thawed (about 12 ½ cups total)
1 (14 ounce) package fully-cooked smoked sausage (such as Hillshire Farm Polska Kielbasa)
1 ½ cups grated sharp cheddar cheese (about 6 ounces total)
1 cup (8 ounces) sour cream, at room temperature
1 medium onion, very finely diced
¼ cup (half of a stick) butter, melted
¼ teaspoon ground black pepper
¼ teaspoon kosher salt
1 (10.5 ounce) can condensed cream of chicken soup
Optional garnish: sliced green onion or chopped fresh herbs such as parsley, chives, basil, or thyme

Preheat oven to 350°F (180°C). Grease a 13 x 9-inch baking dish and set aside. Cut sausage into slices, and then into quarters (so that you have small bite-sized pieces). In a large mixing bowl, stir together all of the ingredients until completely combined.
Transfer the mixture to the prepared baking dish.
Bake, uncovered, for about 40 minutes (or until hot, bubbly, and lightly browned on top).
