Crock Pot French Onion Soup Recipe Notes
- 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.
