I think I’ve used my slow cooker more this month than I have all year. I go through phases using it and I’m currently on the use phase. Saturday I made these slow cooker creamy green chile chicken tacos.
Then last week I was short on time to make dinner so I made slow cooker barbecue chicken for sandwiches. I’ve also been making soup like crazy, so I figured why not make one that can be easily made in the slow cooker. No fuss, minimal dishes and a big pot of this Slow Cooker Broccoli Cauliflower Cheese Soup waiting for you to devour!

There’s probably a hundred recipes for broccoli cheese soup out there, but not as many for broccoli cauliflower cheese soup. Since I always have cauliflower in my fridge I figured combining the two was a great way to differentiate my recipe from some of the others.

Creamy, cheesy soups are ones I generally avoid at restaurants because they’re usually a calorie/fat/sodium bomb. They use excessive amounts of cheese and cream and not so much of the good for you stuff, vegetables. Then of course you have to have a sandwich, salad or at least some warm bread with it, because that bowl of soup isn’t going to keep you full.

I’m happy to report that this Slow Cooker Broccoli Cauliflower Cheese Soup is not a calorie/fat bomb, contains plenty of vegetables, is super thick and creamy like you want this soup to be and it keeps you full!
Instead of using a ton of cream, cream cheese or canned condensed soups to make this soup creamy, I used my favorite protein packed substitute, Greek yogurt! I honestly don’t know how I got by before this thick yogurt came into existence.
While there is definitely a fair amount of cheddar cheese in the soup, it’s probably not as much as you’ll find in many recipes. I used an extra sharp cheddar as a way to get more flavor without having to use as much. This soup is the perfect dinner on a cold night and I’m sure there are plenty of those headed my way. Enjoy!
I’ve got plenty of soup recipes for you to try out and they’re perfect for cold nights! Some are main dish soups, while others you’ll want to pair with protein or one of my salads.

I can not wait to make this tomorrow. My son just had his tonsils and adenoids removed and broccoli cheese soup was his only request. He loves cauliflower too so this will be vegi packed. I’ve never tried Greek yogurt and am excited to try it! Thank you so much for this recipe!
Thanks for giving the soup a try Amy! I’m sorry to hear about your son, hopefully it helps him feel better. I hope you like the Greek yogurt addition, it adds a nice creamy, rich flavor!
Can u use frozen veggies?
Hi T,
I haven’t tried this soup with frozen vegetables, but I imagine it will work just fine.
Hello! I was just wondering what kind of hot sauce you used for this soup! me and my husband are making it this week and we can not wait to try it!
Hi Alexis,
Happy to hear you guys are trying the soup, I hope you like it! My favorite hot sauce to use is Cholula, but feel free to use your favorite or whatever you have on hand. Enjoy!
Ok but how much hot sauce are we to use? it’s not in the recipe list?
The amount of hot sauce you add is up to you. I probably use a couple teaspoons, but it all depends on your tastes.
The soup recipe makes my mouth water… I’ve never tasted or used Greek yogurt for anything… Time to try it out..
We, old folks need a more healthy soup… This just may be it…
Thank you… :O)
Love the addition of cauliflower! Perfect for chilly fall evenings!

I would love a bowl of this for breakfast…this soup looks absolutely fantastic. Comforting and creamy…what a delicious recipe. xo, Catherine
Danae, You are so right–what did we do before Greek yogurt? This soup looks incredible. I can’t wait to give it a try!
I could absolutely use a bowl of this to warm up with today! It’s going to be SO cold!
I love any excuse to break out my slow cooker! I love that this soup looks so thick and creamy, just how I like it. Since the weather has cooled down a bit here, this would be great for dinner this week!
