Crockpot French Onion Meatloaf with Melted Swiss Cheese

In a large bowl, combine ground beef, breadcrumbs, Parmesan cheese, milk, eggs, Worcestershire sauce, salt, and pepper. Mix until well combined.

Form the meat mixture into a loaf and place it in the crockpot.

In a skillet, melt butter over medium heat and add sliced onions. Cook until caramelized, about 20-25 minutes.

Add beef broth to the onions and cook until the liquid is absorbed. Pour the caramelized onions over the meatloaf in the crockpot.

Cook on low for 6-8 hours, or until the meatloaf is cooked through.

About 10 minutes before serving, top the meatloaf with Swiss cheese and allow it to melt.
