Preheat the oven to 375 degrees F (190 degrees C). Spray a 9x12-inch casserole dish with nonstick cooking spray.
Drain hash browns. Combine hash browns, soup, 5 ounces of shredded Colby-Jack cheese, sour cream, Greek yogurt, butter, salt, pepper, and paprika in a large bowl. Pour mixture into the prepared dish. Sprinkle remaining cheese on top.
Bake in the preheated oven until casserole is bubbling and cheese has melted, 35 to 40 minutes.
