Off heat, add sharp cheddar cheese, salt, and optional cayenne pepper until smooth.
Arrange half of the potato slices on the baking tray. Pour half the cheese sauce over it.
Arrange the rest of the potatoes and cover with the rest of the sauce.
Sprinkle the surface with additional grated cheese.
Cover with foil and bake for 45 minutes, then uncover and bake for a further 15-20 minutes until golden and crisp.
Serve hot, garnished with green onions if desired. Every bite of these scalloped potatoes will remind you of the comfort and joy of family gatherings. Savor this creamy, cheesy masterpiece and let it take you back to those precious days at grandma’s house.
