A Sunday roast or roast dinner is a traditional meal of British origin. Although it can be consumed throughout the week, it is traditionally consumed on Sunday. It consists of roasted meat, roasted potatoes, mashed potatoes and accompaniments such as Yorkshire pudding, stuffing, gravy, and condiments such as apple sauce, mint sauce, or redcurrant sauce. A wide range of vegetables can be served as part of a roast dinner, such as broccoli, Brussels sprouts, cabbage, carrots, cauliflower, parsnips, or peas, which can be boiled, steamed, or roasted alongside the meat and potatoes.

British cuisine is the specific set of cooking traditions and practices associated with the United Kingdom, including the cuisines of England, Scotland, Wales and Northern Ireland. According to food writer Colin Spencer, historically, British cuisine meant "unfussy dishes made with quality local ingredients, matched with simple sauces to accentuate flavour, rather than disguise it".
