This is the ultimate hands-off comfort food. A creamy, cheesy mixture coats frozen hash browns, which cook low and slow in your crockpot until perfectly tender and bubbly. It's a forgiving, versatile dish perfect for busy weeknights or feeding a crowd.
For a vegetarian version, use cream of mushroom soup. Do not thaw the hash browns, as this will make the casserole soggy. Avoid cooking on HIGH, as low heat prevents the dairy from separating. Taste the mixture before cooking and adjust salt if needed, as soups and cheeses vary in saltiness.
