Reasons to Love This Chickpea Flour Soup
My version of this classic tastes like classic broccoli cheese soup, but with (ahem) a few wee twists. For example, it is:
- Vegan (dairy-free, egg-free)
- No cheese (not even vegan cheese / plant-based cheese)
- Oil-free
- Grain-free
- High Protein (12.7 g per serving!)
- High Fiber (7 g per serving)
- Low-Carb
- Gluten-free
- Easy-to-make (e.g., one pot, no blending required)
Most of all, it is delicious!

Chickpea Flour: the Secret to Creamy, High-Protein Vegan Soup
Let’s get started, shall we? First, grab your magic wand.
Kidding. But I get it, this all may sound too good to be true.
But it’s not. Then again, chickpea flour is a magical ingredient in many ways. It can be used as a flour, as an egg replacement, and (drumroll) to make dairy-free cheese. Like chickpea flour feta cheese. And (inspiration for this soup) chickpea flour Cheddar cheese.
When a slurry of chickpea flour and liquid is heated (whisking along the way), it becomes thick and very creamy. No milk additions,of any kind are needed. It can be more or less thick, depending on the ratio of flour to liquid. At one extreme, cheese. At the other, the second inspiration for this recipe: French chickpea flour soup.
Ingredients
The exact amounts of each ingredient are indicated in the recipe card at the end of the post. Toggle between US Customary (volume) and Metric (weights) for preferred measurement option.
- 1 large head broccoli
- chickpea flour, (also known as garbanzo bean flour, Cecil flour, or besan)
- nutritional yeast
- tomato paste
- onion powder
- garlic power
- fine sea salt and ground black pepper
- Dijon mustard, (or mustard of choice)
- fresh lemon juice (or more, as needed)
Step by Step Instructions
Note that the complete directions are also in the recipe card below.
Step One: Prep the Broccoli
Cut off the broccoli florets; reserve the stems for another use. Finely chop the florets and set aside.

Use the florets (save the stems for something else) and chop them fine. The broccoli will need to cook in the creamy soup; fine chopping equals faster cooking. It also means you will not have to chew your soup. Who wants a jumbo hunk of broccoli on their spoon? Not me.
If big broccoli floats your boat, I suggest steaming your hunks before adding to the soup.
Note that broccoli is the only chopped vegetable in this soup. Because it is broccoli soup. No onions, no carrots, no thank you.
Step Two: Make the Chickpea Flour Base
In a medium bowl, whisk together the chickpea flour and 1 and 1/2 cups (355 mL) water until blended. Add the nutritional yeast, tomato paste, onion powder, 1 and 1/4 teaspoons salt and 1/8 teaspoon pepper until blended.

Step Three: Cook Chickpea Flour Base
Add the chickpea mixture and the remaining water to a large saucepan, whisking until smooth. Bring to a low boil over high heat, whisking along the way.
Reduce the heat to medium-low and cook, whisking occasionally, for 4 to 6 minutes longer until thickened. Whisk in the mustard.

Step Four: Add the Broccoli
Add the broccoli to the soup, cover, and reduce heat to low. Cook for10 to 15 minutes longer until the broccoli is very tender.
Add the lemon juice, as well as more salt and pepper, to taste.

Step Five: Serve
Ladle into bowls and serve!
My white bean flatbread makes a great accompaniment, especially for dunking!

Storage
Store the cooled soup in an airtight container in the refrigerator for up to three days or the freezer for up to six months.
Cauliflower Variation
Prepare as directed but use an equal amount of cauliflower in place of the broccoli.First up, prep your broccoli.
Happy eating, everyone!

I have only recently stopped eating meat, but I had to take cheese out of my cooking for my daughter-in-law, and then my granddaughter, some years ago. I have really missed it. This, however, was fantastic – absolutely hit the mark for a perfect cheesy soup! I made a double batch, and we finished off all the leftovers in a couple of days. Thank you so much for the recipe!
You are so welcome, Yvette!!:)
I have made this at least 5 times. It’s really good. Sometimes I use frozen broccoli and it is still good.
I was skeptical about this soup, but it is really great. Made it a second time tonight adding some spice to it (chiles). Appreciate what you do here!
This made it into my weekly take-to-work lunch rotation! Even if I wasn’t opting for a healthy meal, I would still gladly dig into this!
This looks easy and delicious! Did you mean to include the chickpea flour in step #2 to mix with the water?
Yes, thanks for catching my error, Shari! The change has been made 🙂
It looks like step two should mention the chickpea flour, but doesn’t? Otherwise you’re just whisking water with water 😉
Thank you! That would be a pretty thin soup:) I made the correction!
