One of my favorite things to cook during the winter is a hearty soup or stew. And this vegan Instant Pot potato soup is exactly that. Potatoes are one of the heartiest ingredients out there, and when added to a rich soup, they create a comforting and cozy meal. Vegan milk and nutritional yeast make this dish super creamy, while a unique blend of herbs and spices make it taste extra wintry.

I’m a huge fan of making soup in the Instant Pot. Using a pressure cooker allows you to get so much flavor in such a short amount of time. This dish is a winter weekday staple in my home, because it takes less than 45 minutes to make. But thanks to the Instant Pot, it tastes like it’s been cooking on your stove all day long.

Notes on Ingredients 

Here are all the ingredients you need to make this creamy, hearty, vegan soup. Check out the recipe card at the bottom of the article for the exact amounts of each ingredient. 

  • Olive oil
  • Onion – I like to use yellow onions for this recipe, but red or white onions will also work.
  • Carrots
  • Potatoes – A mixture of yellow and red potatoes is best for this soup.
  • Vegetable broth
  • Garlic
  • Salt
  • Black pepper – Be sure to use freshly-ground black pepper.
  • Celery seed
  • Paprika
  • Dry mustard
  • Thyme
  • Non-dairy milk – You can use whatever type of vegan milk you prefer, just make sure that it’s unseasoned and unsweetened. 
  • Lemon juice – Make sure you use fresh lemon juice.
  • Nutritional yeast

How to Make Creamy Vegan Instant Pot Potato Soup

Here’s how to make this quick and cozy soup. 

  • Prep. Turn your Instant Pot on to the sauté setting. 
  • Cook the onions. Add the oil and the onions to the Instant Pot, and cook for 7 minutes, while occasionally stirring, then turn off the sauté setting. 
  • Add most of the other ingredients. Place the vegetable broth, potatoes, carrots, garlic, celery seed, paprika, dry mustard, thyme, salt, and pepper in the Instant Pot. 
  • Cook. Place the lid on the Instant Pot, and set the vent to seal, then cook on high pressure for 10 minutes. When the 10 minutes are up, quick release the pressure. 
  • Blend. Take the lid off the Instant Pot, and use an immersion blender to puree the potatoes. If you don’t have an immersion blender, you can transfer the soup to a standard blender. If you want soup that’s chunkier, don’t blend all of the potatoes. 
  • Finish the soup. Add the dairy-free milk, lemon juice, and nutritional yeast to the soup. Stir to combine, then season with salt and pepper. 
  • Serve. Set the Instant Pot to the keep warm setting, and serve the soup. 

Tips for Success

Here are some things you can do to ensure that you get the most out of this soup every time you make it.

  • Use homemade broth. One of the best ways to increase the flavor in this soup is to make your own vegetable broth. Store-bought broth will make for a delicious soup, but nothing beats homemade stock. I recommend using my vegetable broth recipe that uses veggie scraps.
  • Add fun toppings. I love to put fun toppings on my soups. It’s a great way to take them to the next level, while also offering some customization. My favorite toppings for this soup are shredded vegan cheese, vegan sour cream, vegan bacon bits, chives, and green onions. But you can add whatever you’d like! 
  • Make it extra creamy. This vegan Instant Pot potato soup is already creamy, but you can make it even creamier by substituting ½ cup of the non-dairy milk with vegan sour cream.
