Roasted Cheese or Grilled Cheese is a snack made by placing cheese on slices of bread and melting the cheese under a grill. It is a simple meal, popular in the United Kingdom. When prepared correctly, the cheese covers the bread exactly so there are no bitter burnt edges.
Roasted Cheese consists of toast, either buttered or not, with cheese on one side. Further toppings are optional; the most basic being chopped onions (raw or grilled with the cheese), brown sauce or ketchup. Pickled cucumber, Branston pickle, fried tomatoes, fried eggs, Worcestershire sauce and baked beans are also common. Another common variation is to add something to the toast before applying the cheese, such as tomato, or a thin layer of spread Marmite, Vegemite (in Australia), cream spread, mustard or tomato ketchup.
Recipe books and internet articles tend to elaborate on the basics, adding ingredients and specifying accompaniments to make more interesting reading. Consequently, published recipes seldom deal with the most basic form of the dish and frequently refer to the similar dish of Welsh rarebit as "posh cheese on toast".
Cheddar cheese is most commonly used for Roasted Cheese, as this is a particularly good cheese for toasting. Lancashire dairies, in conjunction with a "National Roasted Cheese Day", have promoted Lancashire cheese as the best cheese to use. In Scotland the dish is always referred to as roasted cheese or 'melted cheese', where the bread need not be toasted before applying the cheese.
