A hotdish is a casserole dish that typically contains a starch, a meat, and a canned or frozen vegetable mixed with canned soup that must be served hot or warm. A classic example is made with ground beef, topped with tater tots, and flavored with thick condensed cream of mushroom soup sauce, but some versions in Minnesota use the official state grain wild rice, or even macaroni, in place of the potatoes. The dish originates in the Upper Midwest region of the United States, where it remains popular, particularly in Minnesota, South Dakota, Wisconsin, North Dakota, and eastern Montana. Hotdish is cooked in a single baking dish, and served hot (per its name). It commonly appears at communal gatherings such as family reunions, potlucks, and church suppers.
