A quick and comforting scalloped potatoes au gratin recipe featuring nutty Gruyère cheese and a creamy sauce, perfect for family meals and holidays.
If the top browns too quickly, loosely cover with foil again to prevent burning. Let the dish rest before serving to help the sauce thicken and slices hold together. Freshly shredded Gruyère melts better than pre-shredded cheese. For gluten-free, substitute flour with cornstarch. Variations include adding ham, caramelized onions, or using cauliflower for a low-carb option.
