How to make French Onion Soup without Wine
Cut the onion into rings, and then cut the rings in half.
Place the onions in a 4-quart crockpot. Click here for a 4-quart crockpot.
Add coarse salt, melted butter, fresh cracked black pepper, Worcestershire sauce, and thyme.
Cook on low for 7 to 8 hours until nicely brown and caramelized.
Pour the beef broth into the slow cooker and cook for at least one hour more.
While the broth is cooking, toast the 2 thick slices of crusty bread in a toaster oven.
Cut the toast into large cubes.
Shred the cheese and set aside.
When the broth is almost done, preheat the broiler to high.
Arrange two oven-safe soup bowls on a baking sheet. I use these 20 ounce oven safe bowls for French Onion Soup.
Ladle hot soup into the bowls.
Place the toasted crusty bread cubes on top of the soup.
Sprinkle each bowl with half of the cheese.
Broil until cheese is bubbly and golden, about 2 - 4 minutes.
