Pour can of French Onion soup into the bottom of your mini (2-quart) crock pot.
Place the block of cream cheese on top of the soup then add sour cream. No need to stir.
Place the lid on and set the crock pot on low for about 2 hours.
When done, remove lid and stir well using a whisk.
You will need to whisk it really well for several minutes to get it nice and smooth and remove any bigger lumps.
Top with chopped green onions.
You can keep it warm in the crock pot (just keep the lid on) and have guests help themselves.
The pot I am using here is a 2-quart pot. Perfect for dips like this! If you try to use a bigger slow cooker, it will burn. So if you don't have a mini crock pot, just heat this all up on your stove and stir until combined. Whisk well to remove lumps.
This cream cheese was not softened beforehand. I just took it straight out of the fridge and added it in.
I make this with the Campbell's brand of French Onion Soup. Other brands might not always be as thick as Campbell's soup. If this happens, you may have to add in more cream cheese to gt a thicker dip.
Serve with Fritos or Pita Chips or whatever chip you love!
