    I made this recipe after attending a sponsored event with the North Dakota Soybean Council, my expenses were covered on this trip. I was not compensated for my time and was not asked to create this recipe.

    How will this soup make your life easier?

    Soup is a great meal in the fall and winter when it's cold outside. Instead of feeling like you have to make a protein on the side, add the protein directly into your easy sweet potato soup.

    Make this Protein Packed Mac & Cheese, White Bean & Farro Bowl, Veggie Tacos, or Black Bean Pasta for a quick and easy vegetarian dinner.

    What makes this simple sweet potato soup so good?

    • Sweet Potatoes: use cooked ones
    • Silken Tofu: It makes your soup very silky smooth and adds protein too.
    • Onion
    • Olive Oil
    • Thyme: Fresh thyme is great, you can use dried thyme too.
    • Broth

    How do I make this instant pot sweet potato soup?

    Start making your easy sweet potato soup by preparing vegetables: scrub sweet potato, and slice it in quarters. Slice ends off the onion, and then remove outer layers from onion.

    Pour water into Instant Pot bowl. Place trivet in bowl, place sweet potato, onion, and one thyme sprig on trivet. Close lid, set vent to SEALING. Set to MANUAL, select high pressure and set timer to 15 minutes.

    Cook, then let pressure release naturally for 10 minutes (once cooking is done, let time count up to 10 minutes, then remove lid). Remove thyme sprigs.

    sweet potato and tofu in a blender

    Transfer sweet potato and onion from Instant Pot to high powered blender, or use an immersion blender in your Instant Pot bowl.

    Also add silken tofu, chicken/vegetable stock, olive oil, and salt to high powered blender (no need to chop or break anything up!).

    Select soup setting, blend. Pour your easy sweet potato soup into bowl and serve immediately with crusty bread or your favorite rice.

    Substitutions/Tips

    • Cook the whole sweet potato and onion if you'd like to use them in other recipes (highly recommend!) 
    • The onion will become really soft if cooked with the sweet potato. This is fine for soup, like this easy sweet potato soup or if you were to use the rest in a sauce-like tomato sauce.
    • Thin your easy sweet potato soup with chicken/vegetable stock, heavy cream/other cream, or milk.

    FAQ

    How do you make soup flavorful?

    You can add spices, aromatic vegetables, or a good stock to add flavor to a soup. In this easy sweet potato soup recipe, we use all three: thyme, salt, onion, and vegetable (or chicken) stock.

    How do you thicken a potato soup?

    You can add condensed milk, cream, or silken tofu to make soup thick and creamy. The tofu is a great option because it adds extra protein to soup.

    Can I use another type of squash in this soup?

    Yes, you can swap the sweet potatoes for butternut squash, acorn squash, or other squash. They may require more or less time to cook, but you can definitely swap them.

    What can I make with the leftover ingredients?

    • Sweet Potato: Swap it out for the butternut squash in this Harvest Bowl, or swap for frozen butternut squash in this Roasted Frozen Butternut Squash (bake 10+ minutes less)
    • Tofu: Protein Packed Mac & Cheese, Panko Tofu for One, Pesto Tofu for One, Honey Garlic Tofu for One, Sticky Tofu for One.
    • Onion: chop it up and add to Pumpkin Turkey Chili, Spicy Pickled Onions, Vegetarian Mushroom and Lentil Stroganoff.

      I'm confused -- is it 1/2 or 1/4 package tofu? (Different in ingredient list and instructions.)

      Adding tofu is a great idea to thicken soups! I’ve never thought of that before. I’ve been a vegetarian for nine years and never cook tofu at home bc I’ve never been a fan of the texture but this looks like great way to get in that protein! Definitely keeping it in mind!

        ohh awesome! ya, the texture is hard for me too! using silken tofu is awesome in soups/smoothies because it's all blended and you barely notice it
