For enhanced flavor, consider browning the meatballs in a skillet before baking. This adds a rich, caramelized crust. If Gruyere cheese is unavailable, Swiss cheese can be used as a substitute. Adjust the amount of French onion soup mix to your preference for a more or less intense onion flavor. The sauce can be made ahead of time and reheated gently before serving.
