Pečena raca punjena heljdinom kašom is a traditional meat dish originating from Međimurje. The dish is usually made with a combination of a whole duck, salt, pepper, oil, pork fat, carrots, celery, garlic, onions, and buckwheat. The duck is stuffed with a mixture of buckwheat, duck liver and hearts, carrots, celery, garlic, and onions.

It is then seasoned with salt and pepper, rubbed with oil, and placed in a baking dish with pork fat. The stuffed duck is roasted for about two hours or until the skin becomes crispy. Once done, the roasted duck is left to rest and it's then sliced into individual portions.
