Even with Mac and Cheese Mania over, I’m clearly not over cheddar cheese. I’ll never be over cheddar.

This soup takes flavorful roasted cauliflower and blends it with sharp white cheddar to create a luxuriously smooth and creamy soup. And since I live in Michigan where spring IS NEVER COMING, we’ll be eating soup until the cows come home. (SO COLD. ALL THE TIME.)

(PS: If you love the cauliflower and cheese combination, try my Parmesan Roasted Cauliflower.)

This cauliflower soup is souper easy to make (ha.ha.ha. — this is what being stuck inside does to me). And since it’s against my personal moral code to eat cauliflower without first roasting it, that is obviously a necessary step.

I feel like such a fraud writing that – it might be a bit of an exaggeration. I ate steamed/boiled frozen cauliflower tonight. I was tired. Sometimes a lady just has to dump a  bag of frozen veggies into a pan of hot water and get dinner on the table as quickly and easily as possible. As I write this, today was one of those days.

But I prefer it roasted. As with all things. I had roasted sweet potatoes and red onions for lunch today. I could live on roasted vegetables.

Roasting the cauliflower before pureeing it into the soup adds a great depth of flavor. While it isn’t completely required, it is very very very much required. I mean…recommended.

  • 1 head of cauliflower, roasted
  • 2 tablespoons unsalted butter
  • 1 medium yellow onion diced small
  • 4 cups low sodium chicken broth
  • 1 cup water (or more)
  • 6 ounces sharp white cheddar cheese, grated
  • 1/8 teaspoon cayenne pepper, more to taste
  • salt and pepper to taste


  1. Roast cauliflower. Meanwhile, melt butter in a large saucepan over medium heat. Add onions and saute until translucent or about 5 minutes. Add the roasted cauliflower, chicken broth, and one cup of water. Bring to a boil and boil until cauliflower is very soft (about 10 minutes).
  2. Carefully transfer this mixture to a blender in batches (should take 2-3 batches) and puree until smooth. Return to saucepan, add cheese and cayenne and more water if necessary to thin out the soup. Heat over medium-low heat until cheese is melted and soup is heated through. Serve immediately or cool and store in an airtight container in the fridge for 2-3 days.

Note: Cook time includes roasting cauliflower.

Verdict: I loved this cozy cauliflower soup.
Husband’s take: Honestly, not his favorite. He called it “a bowl of cheese.” He had leftovers the next day but I think he’d be fine not eating it again. Not really man food, I guess.
Changes I would make: None are necessary.
Difficulty: Pretty easy!

  5. I agree with you about the roasted vegetables- something magical happens while they are in that oven! This soup looks great. It’s hard to resist anything with white cheddar in it!

  6. Yummm that sounds perfect for the cold day here. An immersion blender is definitely on my lists of things to get.

  7. This looks so good! I am loving the sound of roasted cauliflower, yum!

  8. sounds tasty and a reason to use my immersion blender

  9. Seriously, when is the snow going to melt? We are only weeks away from spring, and I still don’t believe it’s ever coming. Until then, I’ll eat cheesy soup with you :)

  10. I would love to warm up with this cauliflower soup. I ate way too much this past weekend and this would be a good detox recipe.

  11. I disagree with your husband, I love this soup. My problem is I don’t like to use my blender just for me. I just must be getting lazy.

  12. Roasted cauliflower = yum. Raw = yuck (unless I pile 2x my bodyweight in Ranch dressing on it.)
    I love cauliflower with cheddar, especially one big bowl o’ comfort! Pinned!

  13. I am SO with you…. I will ONLY eat cauliflower if it’s roasted first….. And, umm since we are apparently in the winter that will never end, soup is SO needed. Pinning this one now! Have a great start to your week.
