Creamy Slow Cooker Cauliflower Potato White Bean Soup

by Kaitlynn Fenley

My slow cooker cauliflower potato white bean soup is easy to prep and made in a crock pot. This creamy white bean soup pairs perfectly with crusty sourdough bread for a warm autumn meal.

Slow Cooker Cauliflower Potato and White Bean Soup

The ingredients in this crock pot creamy white bean soup are simple. Here are the most important ingredients, and some tips on what kinds of main ingredients to buy:

  • Cannellini beans: For this recipe, we use already cooked Cannellini beans, also known as white kidney beans, in a can, drained, and rinsed. The beans are added at the end after all the other ingredients are blended for a creamy texture.
  • Chicken Broth: Any broth will do in this recipe. I enjoy the flavor of chicken broth, but vegetable broth works well also.
  • Rosemary and Garlic: It’s important to use fresh rosemary in this recipe. It is much more flavorful than dried. I also use fermented garlic in this recipe, but you can use fresh garlic if that’s what you have.
  • Sauerkraut: Most of our blog readers know that I am a HUGE fan of adding sauerkraut to soups, stews, and braises for the best flavor. In this recipe, you’ll want to use plain sauerkraut or garlic sauerkraut.
  • Green onions: I cook with green onions often, but you can use any type of onion or even leeks in this recipe.

Healthy Cauliflower Potato White Bean Soup

I use my instant pot on the slow cooker setting when I make this soup. You can adjust the cooking time on this soup between 6 and 8 hours. Depending on your work hours, this is a great recipe to throw in the slow cooker in the morning so it’s ready for dinner as soon as you get home! You can cook for 8 hours if that suits your workday better, so the soup is still nice and hot for dinner.

Crock Pot Creamy White Bean Soup

If you eat meat, you can customize this recipe with more protein. I suggest adding in some chicken if you’d like. To keep things vegetarian add in tempeh instead.

Another great recipe from Cultured Guru!
I saw this on your blog about a year or two ago and I finally made it. It’s crazy how creamy it turned out…. and yet the recipe doesn’t call for any cream!! And so flavorful and satisfying on that cold day. I just wish I had some sourdough bread to go along with it. Learning how to make sourdough bread is still on my bucket list and I know it’s covered in your online course. I’ll get to that someday. Anyhow, this is definitely a “keeper” recipe and I’ll be making it again. Thank you for posting it!
