Nutty Sweet Potato Soup with Harissa and Spinach

Nutty Sweet Potato Soup with Harissa and Spinach

Serves 8

30 minutes or fewer

Harissa is a smoky North African chili paste made from smoked chiles, olive oil, spices, and sometimes tomatoes. Heat and flavor vary from brand to brand. This recipe was made with a French-produced harissa with a mild heat and extra sweetness from tomatoes.
  • 2 Tbs. olive oil
  • 2 medium leeks, white and light green parts thinly sliced (2 cups)
  • 3 Tbs. tomato paste
  • 3 Tbs. creamy peanut butter
  • 1 ½ Tbs. harissa paste
  • 2 cloves garlic, minced (2 tsp.)
  • 1 tsp. ground turmeric
  • ¾ tsp. ground cumin
  • 2 medium sweet potatoes, peeled and sliced ¼-inch thick (5 cups)
  • 3 ½ cups low-sodium vegetable broth
  • 3 oz. spinach leaves, thinly sliced (2 packed cups)
  • Lemon wedges, for garnish

1. Heat oil in Dutch oven over medium-high heat. Add leeks, and sauté 5 to 7 minutes. Stir in tomato paste, peanut butter, harissa, garlic, turmeric, and cumin; cook 1 minute, stirring constantly. Add sweet potatoes, broth, and 1 1/2 cups water, and simmer over medium-low heat, partially covered, 20 to 25 minutes, or until sweet potatoes are tender.

2. Blend mixture with immersion blender, adding more water if soup is too thick. Bring soup back to a simmer, and stir in spinach leaves. Serve with lemon wedges.

Will make this again. Added a touch of cayenne pepper to mine to give it an added kick. We all loved it.

Excellent soup! Great flavour. I substituted kale but I wouldn't recommend it, I think spinach would be better.

OMG so delicious! I had been putting off making this, but I'm so glad I finally did. I found Harissa np and the recipe was easy to make. I used almond butter instead of PB, and added a dash of cinnamon. I spared a couple cubed sweet potatoes from the blender to add texture. I will add chickpeas next time for more protein!

I have made this a ton and everyone is always very impressed :) will def make again and I as well just made my own harissa paste, I actually keep the left overs and put it on sandwiches

This was easy to make and delicious. I had to go to a gourmet store to find harissa but it was worth it. This soup is sweet, nutty and spicy at the same time, as well as nutritious. The "hardest" work was chopping up the sweet potatoes and the leeks but you don't have to chop them too fine because it's all blended with an immersion blender anyway. This is a great warm-you-up soup now that winter's almost here.

My boyfriend and I made this recently and it was absolutely delicious! We made our own Harissa paste and used kale instead of spinach. We were blown away by how delicious such a simple soup was!

For tonight

Best soup ever! I haven't had much success finding harissa around here, so I made my own with red pepper (I'm not big spicy fan). I also substitute green onion or even regular onion for leeks. Other than that, I mostly follow the recipe. I probably add a little more onion and garlic because I love them. And as others have found, it sometimes comes out a little thick, so I add a bit of water as needed. It's great with lemon, but I also find it's lovely with a dab of sour cream (if you're not eating vegan-style). I get SO many compliments on this delicious, hearty soup!

I made this last week and followed the recipe exactly, using spicy Mina harissa. I didn't find it spicy at all, but it's an excellent soup. I had considered using kale instead of spinach, but didn't, though I think it would work well also. Initially it was too thick, but I just added water so that I had a total of 10cups of soup, and the flavor is still excellent. I tried it without lemon the first night, but added it the second and it really compliments the flavors in the soup. I will definitely make this again.

I'll make this again! It's quick, tasty and interesting. The harissa I got (DEA) is much too spicy for the amount advised here; I used just under 1 Tbsp and even that was a bit much. I also subbed collards for the spinach and liked that quite a bit.
