Tips & Substitutions

For a creamier texture, consider using Greek yogurt instead of sour cream. You can also substitute the cream of mushroom soup with a homemade version or a different cream soup for variety. If you're short on time, pre-cooked frozen potatoes work well. To enhance flavor, add garlic powder or herbs like thyme to the potato layers.
