Tender meatballs smothered in a rich, flavorful sauce inspired by French onion soup, perfect for any gathering.
For optimal flavor, let the meatballs cook longer on low rather than high. Don't skip browning the onions for that rich flavor. Store leftover meatballs in an airtight container in the refrigerator for up to 3-4 days or freeze for up to 3 months.
