Slow cooker meatloaf infused with French onion flavors from caramelized onions, onion soup mix, and melted Swiss cheese, served with rich juices for a tender, flavorful twist on classic meatloaf.
For best results, use a meat thermometer to ensure doneness. Optional: Add a teaspoon of sugar to onions while caramelizing for extra sweetness. Leftovers reheat well and can be stored in an airtight container for up to 3 days.
