In your slow cooker, add the diced bacon, chicken broth, potatoes, and onion.

Place lid on top and cook low for 6-7 hours or high for about 4 hours.

Once the potatoes are tender and done, cook the bacon grease (or butter) in a small saucepan over medium heat.

Whisk in the flour and continue stirring for about 1 minute.

Slowly pour in the evaporated milk and continue to simmer for about 3-4 minutes, or until mixture gets really thick.

Pour milk mixture immediately into slow cooker and stir to combine.

Add in the cheese, sour cream, salt, and pepper stirring once more until all is well combined.

Serve with toppings of choice!
