Crock pot french onion soup

In a large skillet, melt butter. Begin to cook sliced onions and garlic.

Stir often and cook until onions are thoroughly cooked, about 20 minutes.

Transfer the onion mixture to a 5-quart Crock Pot. Add beef broth, Worchestershire sauce, 1 cup water, black pepper, and sherry (if using).

Cover and cook on low for 6 hours or on high for 3 hours.

Before serving soup, toast bread slices with a slice of Swiss or Gruyere cheese on top. Broil for 3 minutes or until cheese is light brown and bubbly.

Ladle soup into bowls.

Top with prepared toast with cheese side up.
