Cauliflower Soup

My daughter is a little obsessed with Zupa’s Cauliflower Soup because it “doesn’t have any chunks”. The recipe for cauliflower soup I had been using up to that point is one I inherited from my Mom and it is supposed to be chunky. That’s how it was always made at my house growing up and to be quite honest, I like the chunks. But my Brookie Cookie does not and is very vocal about it.

So one day earlier this week, I tried to appease her and create a non-chunky, extra velvety cauliflower soup (in the crockpot no less!) for this daughter of mine.

You guys, I think I might like this creamy version better. The half & half, bacon and cheese might have something to do with it though. Don’t be alarmed, though! Yes, those are high-calorie ingredients, but considering how much soup this makes when you break it down per serving, it’s really not terrible. At least that’s what I keep telling myself.

Of course, you could make this on the stovetop with no crockpot, but if you are busy and have the time in the morning or mid-afternoon to get this cooking ahead of time, I’d recommend doing that. My kids are always extra whiney around 5 pm, so any time I don’t have to spend cooking is appreciated.

Bookmark or print this recipe!! You never know when it might save you on a chilly fall school night 🙂

Have a wonderful day, friends!!

Creamy Crockpot Cauliflower Soup

Cauliflower Soup is a low carb, easy and tasty dinner for those chilly nights ahead! Grab your crockpot, some bacon and this recipe.
servings 6 servings
Prep Time 20 mins
Cook Time 4 hrs
Total Time 4 hrs 20 mins


  • 1/4 cup salted butter
  • 1 large yellow onion diced
  • 3 cloves garlic minced
  • 1/2 cup all purpose flour divided
  • 8 cups chicken stock
  • 1 large head cauliflower cut into large chunks, leaves removed
  • 2 bay leaves
  • salt & pepper to taste
  • 1/2 teaspoon thyme thyme leaves, not ground thyme
  • 1 cup half & half

optional toppings:

  • grated cheddar cheese
  • cooked and crumbled bacon
  • and/or parsley


  • In a medium skillet, melt butter over medium heat. Sauté onion until brown. Add in garlic and cook another minute until fragrant. Sprinkle with 1/4 cup flour and stir to moisten the flour and cook briefly. Pour onion mixture into the bottom of a crockpot.
  • Whisk in chicken stock to crockpot and then stir in cauliflower pieces, bay leaves, salt, pepper and thyme. Cover and cook on high 3-4 hours or until fragrant and cauliflower is very tender.
  • Remove bay leaves from crockpot. Blend soup in a high powered blender until very smooth. Soup should thicken up once blended, but still be on the thinner side.
  • Measure half and half into a microwave-safe large bowl or larger glass liquid measuring cup. Whisk in remaining 1/4 cup flour until smooth. Slowly whisk in 3 cups of hot soup to the half and half. Microwave for 3 minutes, whisking every 30 seconds. This mixture should become very thick. Pour into crockpot and whisk to combine to create a creamy, thick soup. Taste and adjust seasonings. Serve with cheese, bacon and parsley.

    I’ve been craving baked potato soup (but dreading the calories!) – this solves my problem and looks delicious – can’t wait to try it!

    I Hi – I am commenting for the 11/22 giveway 🙂 I made this soup last weekend. I doubled the recipe with the intent of freezing it, but it never made it to the freezer. We loved it – even my kids. I made it with your biscuit recipe. Happy Thanksgiving!!

    I’d love to make this in the instant pot to speed things up, any chance you’ve tried that? Wondering how long I would pressure cook it for? Thanks, love your recipes!!!
