The best-scalloped potato recipes are close to the traditional version but are more unique and delicious. They start with a standard base of potatoes, butter, and onions, and you can add cheese and sprinkle it with chives or cilantro to add more flavor. You can also add sausage or garlic or use a combination of all three. Try layering scalloped potatoes with a cheese sauce for a more decadent version. Once you have chosen your favorite scalloped potato recipes, you’ll have to decide which ones to try.
