A nostalgic French ham and cheese sandwich with melted Gruyère, creamy béchamel sauce, and a perfectly fried egg on top, perfect for brunch or cozy dinners.
If béchamel is too thick, whisk in a splash of warm milk to loosen. Use softened butter for even spreading. Watch broiler carefully to avoid burning cheese. Room temperature eggs fry more evenly. For gluten-free, use gluten-free bread and flour substitute. Vegetarian version swaps ham for mushrooms or caramelized onions.
