    Creamy Broccoli Cauliflower Soup

    Published Mar 15, 2022 · Modified Aug 29, 2022 · by Alexis Joseph · 144 Comments

    Cozy up with a bowl of thick and creamy Broccoli Cauliflower Soup! Packed with veggies, this easy soup makes the ultimate lunch. Dairy free!

    bowl of yellow soup with spoon

    Last weekend I had the best produce in all the land at my fingertips thanks to our lovely CSA box. With the brightest head of cauliflower and broccoli staring at me with puppy dog eyes, I knew a cozy soup was on the horizon.

    My trusty Immune Boosting Soup has totally been my jam lately. And ok fine, this Creamy Tortilla Soup. Amidst all my beloved soup recipes, lately I've been craving the creamy, umami goodness that is this satisfying soup.

    Since so many dairy-free soups call for cashews, I wanted to make a recipe that tasted creamy and cheesy sans having to blend cashews separately or add cheese. Mission accomplished!

    How to make broccoli cauliflower soup

    The creaminess in this recipe comes not from whole milk or cream or cheese, but a simple roux! This traditional method of using flour to thicken (plus cauliflower and potato) lends a super flavorful soup you're guaranteed to slurp up and smile.

    No specialty appliances required.

    1. Cook all the veggies--onion, garlic, carrots, broccoli, cauliflower, and potato. Stir in flour.
    2. Add broth, milk, nutritional yeast. Simmer until veggies are tender then stir in lemon juice for a nice pop.
    3. Blend half the soup, leaving some chunky for texture. Devour!

    Key ingredients

    • olive oil: fat for sautéing our veggies is a must.
    • onion and garlic: aromatics to lay our flavor foundation.
    • broccoli and cauliflower: the cruciferous stars of our soup show! I like fresh but frozen would work just as well. You could also use all broccoli or all cauliflower.
    • potato: the starch helps thicken the soup and add classic broccoli soup flavor! I used two small red potatoes because that's what I had. Yukon or russet are fine, too---no need to peel. Just scrub them really well to get the dirt off.
    • nutritional yeast: cheezy umami flavor. So good. You could also use 1 cup of shredded cheddar cheese.
    • vegetable broth: the liquid gold that brings everything together.
    • milk: I like cashew for creaminess, but almond, soy, or cow's milk all work great. I don't love the flavor of coconut milk here.
    • lemon juice: a pop of brightness in a soup is everything! Don't skip the acid.

    How to serve

    I love a good garnish, don't you?!

    • crunchy croutons or hunks of bread
    • a pinch of ref pepper flakes
    • a drizzle of extra virgin olive oil for ultra richness
    • a sprinkle of fresh parsley.
    • a handful of parmesan or cheddar

    bowl of soup with bread

    How to store

    This soup gets will keep stored in an air-tight container in the refrigerator for up to 4 days.

    Can you freeze this soup?

    You bet. So easy to pull out of the freezer when you haven't thought of lunch!

    1. Place completely cooled soup in a freezer baggie.
    2. Tightly seal bag and remove as much air as possible. Lay the bag flat in the freezer for easy storage.
    3. Once the soup is frozen, you can thaw it overnight in the refrigerator and then reheat contents over the stove or in the microwave.

      This is amazing! Will definitely be a new go-to in the colder months. I made this cooking blender (Pampered Chef brand) and it was wonderful. In order to fit it in the blender I simply halved the recipe. I added everything in at one time at the beginning and it made a creamy version of the above recipe. I also subbed whole milk for the non-dairy alternatives in the recipe sine it's what I had on hand. I can't recommend this enough!

      I made this for my family and they loved it! It was just what we needed in January. The potato I used was fairly large so it was pretty dominant in the consistency and flavor. I would use smaller one next time. I also used whole milk and sharp cheddar (instead of nutritional yeast). Would definitely make this again!

      Sooo good! My grocery store was out of literally everything day after new years, so I subbed fresh for frozen broccoli, frozen cauliflower rice and 1 cup coconut milk for half and half.

      Also skipped the potato and ran out of veg broth but subbed water with Trader Joe’s everything but the chicken seasoning. Seems to be a pretty forgiving recipe. Definitely adding to the rotation

      5 stars with these adaptations to suit my taste 🙂
      • adding lots of dried mixed herbs, chilli flakes and a bit of turmeric along with the onion at the beginning
      • skipping the flour and extra salt
      • adding a tin of chickpeas along with the veggies
      • cooking for 1 hour as that's how long it took for the cubed potato to soften

      I probably make this soup every two weeks and it’s easily gone in 3 days—I’m not even vegan, it’s just THAT good. && My friends love it too—and oh boy, is it hard to share!!! I’m even investing in an immersion blender because I make it so much and it’ll make the recipe a little quicker to make.

      But regardless, This recipe is SUPER easy to make! I always keep nutritional yeast and cashews stocked just for this recipe. To add a little extra creaminess, I blend a handful of cashews with the unsweetened almond milk that I use. If I don’t have cauliflower then I just substitute it for more broccoli

      This recipe is really good for a cold day like we have today. I made a few swaps because I didn't have all the ingredients.

      Instead of nutritional yeast ( I forgot to buy more this week) , I put a little bit of mizo. (so I didn't put lemon because the mizo already has a tanginess to it. )
      I didn't have fresh cauliflower and broccoli, so instead I put frozen ones.
      And to add to the creaminess, I blended about 1/4 of the mix once it was cooked, it makes it a really nice.

      Thank you for this nice recipe. Simple ingredients and so yummy.

      Absolutely THE BEST vegan broccoli “cheese” soup! I love that the creamy base comes from potato and the flour (although I use arrowroot starch and sweet potato and it’s amazing). I can’t have cashews so it’s nice to see a vegan recipe without them! Love following your blog and all the recipes are delicious!

        I'm so glad it can fill a void for cashew-less recipes. Thanks for letting me know you loved it, Liana!

      I changed the seasonings to fit my own palette (almost tripled the nutritional yeast). I didn't add the carrots since I just had my wisdom teeth removed and wanted something less crunchy. Overall, good recipe!! I like this one better than the one on the Whole Foods website.
