What makes a meatball Swedish? Like any food tradition, recipes vary from person to person—but a few key characteristics generally remain the same. Firstly, the size: small cocktail-size meatballs. And secondly, the sauce: a rich creamy, broth-based sauce. Serving Swedish Meatballs over egg noodles aren’t a key deciding factor, but it does make an extra delicious addition, perfect for soaking up the creamy gravy.
