Sauerkraut can be heated on the stove in a saucepan or skillet, in a microwave in a covered, microwave-safe bowl, or in the oven in a covered casserole dish. Sauerkraut can also be mixed with baked dishes, such as potatoes, or used as a topping on a hot sandwich.
Sauerkraut is occasionally used as an ingredient in soups and stews. Pureed sauerkraut mixed with warm yogurt makes a flavorful sauce for meat and potatoes. In general, sauerkraut should be rinsed before it is used as an ingredient to prevent it from overwhelming the rest of the flavors in the dish.
