Slow Cooker Cauliflower Soup topped with bacon, cheese and chives is the perfect comfort-food, and it’s keto-friendly. Just add all the ingredients to your crockpot and go!
Cauliflower is a perfect, low-carb swap in recipes! Mashed Cauliflower, Cauliflower Fried Rice, and Cauliflower Buffalo Wings are just a few favorites in our house. But my favorite cauliflower dish of all time may be this easy cauliflower soup.
And though my instant pot has been getting more and more attention lately, I’m making this cauliflower and leek soup in the slow cooker.
Why?
I love the fact that you can just dump everything into the crockpot in the morning, and then have dinner waiting for you in the evening. It’s especially useful if you work during the day, or if you’re out and about with the kids, or if you have a potluck to attend.
This is one of those magical slow cooker recipes where there’s no browning or extra steps required. You just throw everything into the pot and let it cook away. You can even add everything to the slow cooker insert the night before, stick it in the fridge, and put it in the crockpot the next morning. That makes things extra easy!
Then, when you get home, just use an immersion blender to blend it to that amazing, creamy consistency, and stir in some heavy cream and cheddar cheese.
I love using sharp cheddar cheese in this recipe. And Cabot makes one of my favorites! They have so many varieties to choose from, but I’m using their New York Extra Sharp Cheddar Cheese in this recipe. However, if you’d like a spicy soup, try swapping it out for their pepper jack. For a pop of color, I topped the bowls with some shredded Cabot Medium Cheddar Cheese.
