It has been freezing in my apartment lately, and all I’ve wanted is to eat rich, warm soup. Usually, my go-to low carb vegan soup is my faux-tato leek soup, but I had approximately zero leeks in my house and somehow even less desire to go out to the store. So, I decided to make a low carb vegan creamy broccoli soup. Who doesn’t love a good broccoli soup? Typically you see more broccoli cheddar type soup recipes out there, but in the interest of keeping this keto-friendly, I opted to leave out any dairy-free cheddar substitutes and use nutritional yeast for that cheesiness instead.
In addition to being vegan, and thus dairy free, this soup is also sugar free, soy free, gluten free and paleo! It’s also AIP friendly if you substitute the cashew cream for coconut milk, which is pretty awesome, as vegetarian and vegan auto-immune recipes are kind of hard to come by!

This recipe is pretty simple and is made entirely out of common ingredients. The one outlier might be nutritional yeast, as it isn’t that typical in non-vegan cooking. Nutritional yeast is high in protein and B vitamins and gives a somewhat cheesy taste to whatever you add it to. While similar nutritionally, nutritional yeast is different from brewer’s yeast or baker’s yeast and the three cannot be substituted for each other.
I usually buy my nutritional yeast online in bulk, but you can also find it in most grocery stores. I usually find it in the health food aisle, but also often see the Bob’s Red Mill brand in the baking aisle of my local grocery store. And of course, any health food store should carry it.

Notes on Making Vegan Low Carb Creamy Broccoli Soup
- You will note that this recipe calls for celery… do not panic. The end result doesn’t at all have a celery taste. However, if you’re somehow morally opposed to celery (I get it), you could definitely use an equivalent amount of broccoli or cauliflower in its place. Keep in mind that this will increase the amount of net carbs in the total recipe.
- To make this recipe nut-free, you can simply replace the cashew cream with canned coconut milk (low fat or full-fat, it’s really up to your preference). I like the coconut milk from Trader Joe’s, as it’s affordable and doesn’t contain any fillers.
- You will also notice that I use onion and garlic powders instead of the fresh version of these aromatics. I like to use pantry staples wherever possible lately, as I’m a girl on a budget. I also find that the powdered spices pack more flavor for fewer carbs.
- I have used both a Vitamix and an immersion blender to blend this soup and both produce smooth results.
- To calculate net carbs – subtract the grams of fiber from the total grams of carbohydrates in the recipe. Net carbs for this recipe: 12g total carbs – 5.3g fiber = 6.7g net carbs
- While I strive to provide accurate nutrition information, there are variations across brands and types of ingredients. So, if you’re using other brands than those mentioned, your macros may be different. All nutrition info is calculated from the USDA values for each ingredient, unless a brand is specifically mentioned (or no generic listing is available), and are for information purposes only!

Use the plant-based ingredients specified in the recipe and check packaged products for hidden dairy or allergen ingredients.
What can I serve alongside it?
Pair it with the vegan keto rolls or another simple low-carb side.





Sounds yummy! Why would someone be morally opposed to eating celery? Is there something I don’t know or is it a joke? lol! Thanks!
Haha, I can’t believe I just saw this now – sorry for the extreme delay! It’s just a joke, because I’m a little bit of a weirdo. :D
Hi I don’t have celery in the house or cauliflower any suggestions on what I could use for substitutes for these?
Hi! You could use more broccoli instead, or even leeks (though they are a bit higher in sugar). Frozen spinach would be another option that is low carb and would still taste delicious!
This is delicious! Definitely going to be making it regularly :) needed a low carb vegan soup!
Thank you, Jenna! I’m so glad you liked it!
Sooooo yum!
Thank you!! :D
per serving 1/4 of a cup?
Oh! Per 1/4 of a recipe :) It’s a little more than a cup.
We seriously have made this so many times. Great and super easy!
I’m so glad to hear this, Tricia! Thank you for sharing!:D
I’m allergic to celery (believe it or not – lettuce, too). Sigh… Do you think I could substitute cucumber for the celery? I’ll probably try it – just thought I would ask ya’ though. Thanks.
I believe it! I’m not sure how cucumber would turn out with this. Maybe cauliflower or broccoli instead? I’m curious though – how did the cucumber work?
What can you use instead of coconut cream as I have bad effects from this ingredient
Hi Ellen, good question! You could substitute in any unsweetened non-dairy milk for the coconut cream. The soup won’t be quite as creamy, but will still be delicious!
Going to make this tonight for my vegan dinner guests. Thanks for the recipe!
I hope everyone enjoyed it, Tammi! :)
Does it taste like coconut?
Hi, Liz! This pretty much depends on what brand of coconut milk you use. I’ve noticed that some are more “coconutty” than others. When I make it with the Target brand (Simply Balanced), it doesn’t taste like coconut, though. I hope this helps! :)
This soup is brilliant, delicious and I’ve made it least 4 times lol. It freezes really well too. Also, I love your cookbook. I just bought it. Thank you for the wonderful recipes!
I made this tonight and it was delicious! I would like to make it a little thicker though – do you think I decrease the liquids or add another cup of broccoli?
I only found this recipe four days ago and I’ve already made it twice. I just throw in a bag of frozen broccoli and zucchini mix, then whatever low-carb vegetable scraps that I need to use up. It’s filling, healthy, delicious, and is great hot or cold.
It’s especially delicious with a splash of pickle juice and a bit of Riviera plain coconut milk kefir. Very versatile, thank you for this recipe!
Hi Liz, I really appreciate this recipe. Very simple, and fast to put together.
My husband has had Covid all week. And I think I’m getting it also. so I really appreciate that I didn’t have to chop an onion and garlic.
I did forget the nutritional yeast at the end. I put some TJs gluten free savory crackers on top to give it some crunch. Well, I did the best I could. Thank you very much. There’s one serving more and I’ll try that with the nutritious yeast tomorrow for lunch (four servings is 3 servings for us. )
Very cold snd stormy in So Cal. I wanted something warming. Thanks
I’m glad you enjoyed the recipe, and hope your husband feels better soon!
This was excellent! We just had it for the first time. A rainy day in Southern California (one of the few! ) We gave it a 10!! I’m so glad it’s dairy free AND low carb! Thank you very very much
But it must have cooked down or something . We each had 1 1/2cups of soup. I measured. There’s only about 1 Cup left! Yet your recipe says 4 servings of 1 1/2 cup each. And we really had only two servings
Maybe it’s because I used a pound of FROZEN broccoli? Would that change things?
Thank you again. Hubby put crushed tortilla chips in his, and loved it
Hi Judy, I’m so glad you liked it! It sounds like you might be onto something and that the frozen broccoli didn’t put out as much liquid as the fresh. I’ll put a note in the recipe about this and make sure to suggest adding a little water if using frozen broccoli. Thanks for letting me know. :)
Just a comment for budget conscious people– We eat about 4.5 lbs of food a day, and the best strategy is to reduce price per pound. Usually onions are cheaper than any of the other ingredients here, so budget-wise, sauteeing an onion with the celery over onion powder is likely to save on budget in the long run. I have this cooking in an instant pot right now- was called away unexpectedly, and looking forwards to eating it on my return!
