Slow Cooker French Onion Soup

Very Tasty French Onion Soup in Crock Pot

My Granny had French roots and she was the best at cooking this gorgeous French onion soup that smelled so good directly when opening the door. Don’t forget to finish it off the traditional way, topped with a slice of bread and melted cheese, making it one of our all time favorite comfort foods that warms us up from the inside out!

It’s a soup you can serve as appetizer of even for as a main dish! The longer you cook it the more tasty it will be. That’s where the slow cooker becomes very handy 🙂

HOW TO:

Place chopped onions, butter, and olive oil in a large skillet or pot, and cook over medium heat for 10-15 minutes, or until onions start to caramelize.
In a small bowl, whisk flour into balsamic vinegar and Worcestershire sauce and mix until smooth.
Transfer onions to slow cooker. Pour in beef broth, bay leaf, salt, pepper, and flour mixture, and stir well to combine.
Cover and cook on low for 6-8 hours, or on high for 3-4 hours.
Ladle soup into oven proof bowls, top each with 1 slice of bread and cheese, and broil, about 5 minutes or until cheese is melted and bubbly.
Garnish with chives
