When people ask Alex and me how to get started eating more vegetables, we often say, “Start with soup!” Why? Soups are usually simple to put together, and a delicious way to eat a lot of vegetables at once. Soups hit the big three for us: they’re healthy, tasty, and easy to make. And this vegan sweet potato soup recipe with harissa is absolutely that. The soup is made creamy using peanut butter, and topped with crunchy peanuts and that bright red harissa, it’s visually stunning too. Also: soups are also easy for toddlers to eat, which makes them kid friendly enough for our son Larson! Keep reading for this sweet potato soup recipe and more harissa recipes.

How to make this vegan sweet potato soup recipe

This vegan sweet potato soup recipe is nourishing, delicious, and can easily fit into your everyday life. It works for a weeknight meal or an evening entertaining friends, and is served with harissa, a North African red pepper paste (see below). To get maximum flavor out of this soup, onion and garlic are sauteed together, then cooked with sweet potato and spices like cumin and turmeric.

The magic ingredient? Peanut butter. It gives a creamy, savory undertone to the soup while keeping it vegan. To get maximum nutrients, we added some cooked spinach that’s stirred in at the end and wilted for about 1 minute. Topped with crunchy peanuts, this sweet potato soup is a tasty way to get a variety of nutrients that help fight off the winter blues.

What is harissa?

Harissa is a North African red pepper sauce that adds a rainbow of flavor to the dish. It’s not so much spicy as flavorful, if you buy the mild variety as we did. But, you can also buy a spicy variety that really kicks it up a notch! You can find harissa at most grocery stores in the International aisle.

Creamy Sweet Potato Soup


  • Author: a Couple Cooks
  • Prep Time: 10 minutes
  • Cook Time: 35 minutes
  • Total Time: 45 minutes
  • Yield: 4 to 6 1x

Description

This sweet potato soup recipe is full of flavor! Peanut butter and spices help form a deliciously creamy soup base.


Ingredients

Scale
  • 1 yellow onion
  • 3 cloves garlic
  • 2 pounds sweet potatoes
  • 2 tablespoons olive oil
  • ¼ cup tomato paste
  • ¼ cup creamy peanut butter
  • 1 teaspoon ground turmeric
  • 1 teaspoon ground cumin
  • 4 cups vegetable broth
  • 1 ½ cups water
  • ½ teaspoon kosher salt
  • 4 cups packed baby spinach leaves, washed (or chopped standard spinach leaves)
  • Mild harissa
  • ½ cup crushed peanuts

Instructions

  1. Dice 1 onion and mince 3 cloves garlic. Peel the sweet potatoes, then slice them into 1/4-inch thick rounds.
  2. In a large, heavy-bottomed pot, heat 2 tablespoons olive oil over medium high heat. Add the onion and sauté for 5 to 7 minutes, until soft.
  3. Stir in ¼ cup tomato paste, ¼ cup peanut butter, garlic, 1 teaspoon turmeric, and 1 teaspoon cumin, and cook 1 minute, stirring constantly.
  4. Add sweet potatoes, 4 cups vegetable broth, and 1 ½ cups water. Simmer over medium-low heat for 20 to 25 minutes until sweet potatoes are tender.
  5. Once sweet potatoes are soft, blend the mixture with an immersion blender (or transfer to a blender). Stir in ½ teaspoon kosher salt. Bring soup back to a simmer, and stir in the spinach leaves. Heat until wilted, about 1 minute.
  6. To serve, garnish with a dollop of harissa and sprinkle with crushed peanuts.

Notes

You can substitute kale or chard for the spinach in this recipe; just cook the soup until the greens are tender (kale and chard take slightly longer to cook than spinach).

Harissa is a North African chili sauce that brings an integral flavor profile to the soup. Ours was a purchased mild red pepper harissa; spicy blends are also available if you’re looking for additional heat.

    1. You’re correct — noted in the recipe! Not sure whether harissa is available at Trader Joe’s, but it seems like a product they would carry. We got ours at Fresh Market. Hope you enjoy!
