It’s easy to make this delicious French Onion Soup with a few simple steps in your slow cooker. Add a thick piece of crusty bread and cheese for a tasty topping! In French you say, Soupe à l’Oignon Gratinée!
It’s easy to make French Onion Soup. Did she say EASY? Yes, it can be easy, with a few simple steps and a slow cooker.
Let’s start with the onions. While most recipes state that onions cooked on the stove caramelize in 15 or even 25 minutes, you’re lucky if they are done in 45 minutes. Since caramelizing onions truly requires more time than many of us have for an average weeknight recipe, this method of “low and slow” caramelizing in the slow cooker over night will not only be a time saver, but will also produce a rich, deep savory flavor perfect for your soup starter.
Add all the remaining ingredients to the slow cooker in the morning and go on with your day!
This recipe is for an onion soup without the thick crusted topping. But if that is your preference, see our Gr8 tip below. Delicieux!
