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!

Crock Pot French Onion Soup Recipe Notes

• 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.
