My dear Husband loves Crockpot French Onion Soup.Every time we take a cruise he looks forward to the evening they serve French Onion Soup.
Since we sadly do not have a cruise on our schedule right now I figured I would try my hand at making his favorite soup.
Well you know I had to give it my own spin and make it in the crockpot.
So without further ado...Crock Pot French Onion Soup
One of the best things about this slow cooker French Onion Soup Recipe is how easy it is to make. The only thing you do that is not in the slow cooker is cooking the onions to make caramelized onions on the stovetop. You can also do this in your slow cooker if you have one that is a multi-cooker.
This crockpot soup recipe only takes a few ingredients including sliced onions, butter, sugar, and broth. When the slow cooker French Onion Soup is done, you will want a few bread slices and good cheese to broil over the top to finish it off.
This recipe always makes me laugh and shake my head at the same time. It brings back memories of my husband and I taking off for an unplanned road trip to Glacier National Park a few years ago.
We randomly decided mid day to hop in the car and drive to Montana for the weekend. As we were pulling into Missoula to get gas I remember that I had started crockpot French Onion Soup that morning for dinner.
I had to call our amazing neighbor and ask if she would stop by and turn off the slow cooker. She was more than happy to stop in and find dinner ready for her.
Now when we travel she always asks if there is going to be dinner waiting for her in the crockpot when she stops to check on the house.
Ingredients
- Unsalted Butter
- Onions
- Sugar
- Beef broth/Vegetable Broth
- French bread/Baguette slices
- Gruyere cheese or Swiss cheese
Optional - Bay leaf, fresh thyme sprigs, Worcestershire sauce, sherry, brown sugar
Bread - We like to use a crusty bread that will hold up to floating in the soup.
Equipment Needed
vegetable chopper - This is a huge time saver for chopping onions.
Crockpot - We suggest using a crockpot that has a digital timer that automatically switches the slow cooker to warm after a set amount of time. This helps make sure your soup cooks perfectly and you don't have to stress about what time it is going to be done.
Soup Bowls or French Onion Soup Bowls
Recipe Tips
The hardest part of this entire recipe is chopping up the onions. They always make me tear up and have red eyes for a while. Let me know if you have any ideas on helping stop crying from onions.
Amazon sells French Onion Soup Bowls that look great! They also have this set of French Onion soup bowls with handles that look fun.
When you put the soup bowls in the oven to toast the bread and cheese make sure to put them on a baking sheet. This will make it a lot easier to remove them from the oven.
What are the best onions to use for French Onion Soup?
I like to use regular white onions for Slow Cooker French Onion Soup. Sweet onions tend to make the soup a bit too sweet for us.
Can you make Vegetarian Slow Cooker French Onion Soup?
Yes, You can switch out the beef stock for vegetable stock to make this an epic Vegetarian Crockpot Soup.
