The Best Slow Cooker French Onion Soup, that is simmered in a red wine, chicken and beef stock. Topped with Gruyere cheese and scallops!
Your going to want to get yourself a set of some good quality oven proof bowls and then you will be in business to make the best french onion soup ever.
Typically people caramelize there onions on the stove for a minimum of 45 minutes or more, turning them often.
However if your pressed for time then you can let the slow cooker do that work for you and save you that hassle.
Now I don’t know about you but cutting 6 large onions is a pain, so another way to make this job easier is to allow your food processor do most of that work.
Of course your going to still peel each onion and cut diagonally before placing in the processor to slice.
But I promise you, it can be done in half the time this way and each onion will be cut perfectly too.
As long as you are using a good food processor such as the one I use and recommend below.
Traditionally french onion soup is topped with Gruyere cheese, however you can substitute for swiss which is similar in taste.
I like to use Gruyere through which can be found in most European markets. This recipe will make roughly 5 large bowls of french onion soup, or 6 small to medium.
So if you have any any leftovers “which is highly unlikely” unless it’s just you, then you can enjoy it over the next few days or share with those lucky enough to be around the kitchen with you.
To make this soup you will want to have a slow cooker and food processor which will saves you a ton of time.
Otherwise you can caramelize the onions on the stove top anywhere from 45 minutes to an hour stirring often till they caramelize to get the job done.
And slicing the onions by hand, but I much prefer using the food processor and slow cooker to get these tasks done.
Adding scallops on top the toasted bread and cheese is an option, not a requirement. But trust me it makes each bowl even that more special, I use medium sized scallops you can use small, medium or large.
More or less, totally depends on you, after all this is your soup, right? Serve hot directly from the oven and you will be in French Onion Soup heaven in no time!
