Slow Cooker Sunday: Creamy cauliflower soup without heating up the kitchen

Need a tasty way to use up that head of cauliflower that’s been sitting in your refrigerator? This easy slow cooker soup is rich and creamy and packed full of cheddar cheese flavor, but you don’t have to slave over a hot stove to make it.

Fresh cauliflower is added to the slow cooker, along with vegetable broth, heavy cream and spices, and is simmered until the cauliflower is nice and tender. Once cooked, just use an immersion blender to blend your soup with two kinds of cheese right in the bowl of the slow cooker.

And don’t forget to top off your bowls with bacon pieces and slices of green onions.
