How to Make French Onion Soup in a Slow Cooker

Cris here.  I LOVE me some Crock Pot French Onion Soup. So when a reader wrote me to ask for a crock pot French onion soup recipe I suddenly realized we didn’t have one on the site! Today we are remedying that!

  • The recipe we use in my house is an adapted version from Gooseberry Patch’s 101 Slow Cooker Recipes with my mom’s cheesy garlic bread on top!
  • This recipe calls for 3 cups of onions sliced. I had 3 medium to large onions and that easily made 3 cups. I loved using my food processor to slice the onions VERY quickly. Little known fact about me… I used to HATE food processors. THIS one totally made me change my tune.  I love how easy it is to use.
  • I crocked this up in my Cuisinart Multi-Cooker which has a browning setting that allowed me to sauté my onions in the until before switching it over to slow cook.
  • If you don’t have a multi-cooker you can just cook your onions in a skillet and then transfer to any 4-6 quart slow cooker.
  • Looking for more recipes? Our Recipe Finder can help you find exactly what you need.
  • Check out all our favorite recommendations for cookbooks, slow cookers and low carb essentials in our Amazon Influencer Shop.
  • As with any of our recipes, carb counts, calorie counts and nutritional information varies greatly. As a result, your nutritional content depends on which products you choose to use when cooking this dish. The auto-calculation is just an automated estimate and should NOT be used for specific dietary needs.
  • All slow cookers cook differently, so cooking times are always a basic guideline. Recipes should always be tested first in your own slow cooker and time adjusted as needed.

Instructions

  • Melt 1/4 cup butter in a skillet and cook onions until soft.

    Is there a substitution for sherry? I’m really not a fan.

      We haven’t tried this with a substitution, but think replacing the 1/4 cup of sherry with 1/4 cup additional broth might work well. If you give it a try, let us know how it goes!

    Soup had a good flavor even though I didn’t add sherry since I didn’t have any. I wish I read the comments before making the soup. It tasted a little too sweet for me. it doesn’t need the sugar. Next time I will make it without. Very easy to make. Thank you ?

    Can you cook this on low for up to 8 hours? Or is it best to cook it on high?

    There are so many types of onions…what types do you suggest to use or does it not matter? Do some produce a stronger flavor?

      Hi Claudia-

      We used sweet yellow onions. I would imagine that different onions will likely bring out different flavors.

      Enjoy!

    I have prepared this recipe. I didn’t care for the addition of the sugar. Yes, the addition of sugar helps to carmelize the onions, but I prefer the soup without the sugar.

      Hi Virginia- Thanks for the feedback. We used sweet onions in our soup so the added sugar really didn’t bother us, but this is very good to know for folks who would prefer not to add the sugar.
