Ajdova kaša is a traditional dish originating from Slovenia. Although there are many variations, it's usually made with a combination of buckwheat, vegetable stock, onions, garlic, mushrooms, bay leaves, fat, parsley, salt, and pepper. The buckwheat groats are covered with the stock and slowly simmered in a pot with bay leaves and salt.

The onions are sautéed in oil or butter and mixed with the mushrooms, garlic, salt, and pepper. The mixture is cooked until the water evaporates and it's sprinkled with chopped parsley. It is then mixed with the buckwheat, and ajdova kaša is typically served with roast meat or sauerkraut.
