Cauliflower Potato Soup with Peas

This creamy, vegan cauliflower potato soup with peas is chunky, hearty and full of nutrition and flavour. This recipe is gluten-free, oil-free, sugar-free and low in fat.

Equipment Needed

To make this creamy potato soup, you’ll need a:

• Stock pot. A 4-6 quart stockpot is perfect for making this soup.
• Blender or immersion blender. A Vitamix will produce the best result but any blended will work. You can also use an immersion blender right in the soup.

Ingredients Needed

This soup is easy to make with basic ingredients. Here’s what you’ll need:

1. Vegetable basics. For the base of this soup, I used onions, garlic, celery and carrot. The onion and garlic are must-haves but if you’re missing celery or carrot, you can use a bit more or less of either.
2. Vegetable broth. I used vegetable bouillon cubes but any store-bought or homemade broth works.
3. Cauliflower. You’ll need a few cups of fresh cauliflower for this soup.
4. Potato. I used russet potato in this soup but red and Yukon gold potato also work well.
5. Herbs. I used dried parsley and thyme for seasoning but you can play around with seasonings to create different flavours. Sage, rosemary and oregano all work well. You could also add a bay leaf as it simmers, just make sure you remove it before blending.

How to Make Cauliflower Potato Soup

I made this soup stovetop but it can also be made in an Instant Pot. I’ll include the Instant Pot instructions after this section. This soup is easy to make and will take less than 30 minutes from start to finish. Let’s go over the steps.

Step 1: Saute the veggies, then add the herbs.

The first step is to cook up the carrot, onion, garlic and celery for 6-7 minutes with a pinch of salt and pepper to create a flavourful base for the soup. You can saute using a few splashes of water, vegetable broth or 1 tbsp of olive oil. I used 1/4 cup vegetable broth.

After those have softened and become fragrant, stir in the dried thyme and parsley and cook for a few more minutes.

Step 2: Add the chopped cauliflower, potato and broth.

Next is to add the chopped cauliflower, peeled and cubed potato and vegetable broth. Now that you’ve added everything to the pot, you’ll simmer it, uncovered, for 15 minutes until the potato and carrot are tender.

Quick tip: I like to stock organic vegetable bouillon cubes in my pantry so I’m always ready to make soups, stews and chili.

Step 3: Blend half the soup.

Once the soup is cooked, either use an immersion blender right in the pot, or carefully scoop about half of soup into a blender. Blend until smooth then pour it back into the pot with the unblended portion.

Do I have to blend the soup?

No, blending is not required but it does create a beautifully creamy but hearty soup with bites of potato and veggies in every bite.

Step 4: Stir in the peas and serve!

The final step is to stir in 1 cup of fresh or frozen green peas and season with salt and pepper. Now the soup is ready to enjoy!

Do I have to add peas?

No, you sure don’t! If you’re not a fan of peas, you can leave them out or substitute them with corn.

Instant Pot Method

Want to make this soup in an Instant Pot? No problem! It’s super easy. Here’s how:

1. Add the carrot, onion, garlic and celery to the Instant Pot with 1/4 cup broth or water and use the “Saute” setting to cook for 6-7 minutes, stirring often.
2. Stir in the herbs and cook a few more minutes.
3. Add everything except the peas and seal the lid, making sure the Venting Knob is set to “Sealing”.
4. Press “Pressure Cook” and set the timer to 10 minutes.
5. When the timer beeps to indicate cooking has finished, carefully move the Venting Knob to “Quick Release” to let the pressure out.
6. Once the Float Valve drops, open the lid and proceed with steps 5 and 6 in the recipe card below.
