Instructions

1. In a large, heavy-bottom pot (I always use my dutch oven for soups) heat the oil over medium heat.
2. Add the onions and cook for 3-5 minutes until translucent but not browned. Add the garlic and ginger and continue to cook for another minute. Add the turmeric, paprika, chili powder, cumin, red pepper flakes, cinnamon and salt and stir to combine with the onions. Stir in the tomato paste and cook for another minute.
3. Add the sweet potatoes, tomatoes and vegetable stock and stir to combine. Bring soup to a boil then reduce heat to medium-low and let simmer for 25-30 minutes until sweet potatoes are very tender.
4. Stir in kale and let cook for another 3-5 minutes until kale is wilted and very tender.
5. Add the lime juice and peanut butter and stir until well combined. Season soup with additional salt, lime or red pepper flakes if needed.
6. Serve immediately or refrigerate in an airtight container for up to 4 days.

HOW TO MAKE THIS PCOS-FRIENDLY SPICY PEANUT SOUP…

This soup is great served right away and also REALLY great to make for the week because hanging out in the fridge for a day or two allows the flavours to mingle and get to know each other. I think I might even like this soup the best at about the 2 days mark. 

Don’t let the long-ish list of ingredients fool you here! This spice combination is totally worth it and using both tomatoes and tomato paste gives this soup a depth of flavour that is a chef’s kiss emoji times 100. 

PRO TIP: If tomato paste isn’t something that you use all that often, take the remainder of the can and freeze it into 1-tablespoon portions so it doesn’t go to waste. And that way you can easily bump up the flavour and richness of another future recipe. 

My next nugget of advice for this recipe is to take the time to uniformly chop the sweet potatoes. Aim for 1 cm cubes at the most because the smaller and more uniform the sweet potatoes are… A) your soup will cook more evenly, and B) the soup will have a much better texture – I’ve tried this soup with a super rustic cut potato and it’s just not the same with bigger chunks of the potato. Stick with a 1-cm sweet potato cube, please!

Any type of tomato will work here as long as they are chopped (unlike the sweet potato, it doesn’t make that much of a difference if your tomatoes aren’t all that uniform). I usually always have cherry or grape so I love those here but really any tomato will 

do the trick, even drained diced tomatoes from a can will work in a pinch.

The peanut flavour in the spicy sweet potato peanut soup recipe comes from peanut butter. I always have a jar of smooth peanut butter on the go and that’s what I used here. I am definitely, 100%, will always be a smooth PB gal so something like crunchy peanut butter barely ever makes it into my kitchen. With that said, I haven’t tried this soup with anything but smooth. I’m sure the crunchy PB would give this soup much more texture and maybe even more peanutty flavour so if you do make it with the crunchy type of peanut butter please let me know in the comments.

Most of the spice in this spicy soup comes from the ginger and red pepper flakes. The spice level of this soup as it’s written is rather mild so if you like things super spicy you can add a pinch (or 2… or 3) of cayenne into the pot with the other spices OR stir in a couple of dashes of hot sauce or some extra red pepper flakes to your liking.

And what’s a healthy, wintery soup recipe without some greens, right? My kale of choice these days is the black kale variety (aka Tuscan kale, black cabbage, dino kale). It’s a little bit more delicate (if kale or other cruciferous vegetables could ever be described as delicate) but any kale will do. Or more like any green will do – give spinach, chard or collards a try.

SWEET POTATO PEANUT SOUP RECIPE FREQUENTLY ASKED QUESTIONS

Is Spicy Sweet Potato Peanut Soup PCOS-Friendly? Is it healthy?

Yes and yes! 

This soup uses some amazing (and both nutritious and delicious) PCOS-friendly ingredients (read: real, whole foods that will not only give your body the nutrients it needs but will work to help keep your blood sugar nice and stable too). 

Not all soup recipes are PCOS-friendly so if you’re scrolling Google or Pinterest looking for a cozy soup recipe make sure to read through the ingredients list – my PCOS-Friendly Foods Cheat Sheet can be so helpful in determining whether a recipe or ingredient is PCOS-friendly or not. 

Is this soup really spicy?

This soup is definitely on the mild side of spicy. The heat from the ginger-chili powder-red pepper flake combo is beautifully balanced with the sweetness from the sweet potato and creaminess from the peanut butter and acid from the fresh lime so although there is some heat there it’s not overpowering. 

If you do like really spicy things, feel free to add cayenne pepper, hot sauce or extra red pepper flakes to your pot. 

Can I freeze this soup?

I don’t think this soup freezes all that well do to the sweet potatoes and would not recommend this one for the freezer. Keep it in the fridge and enjoy it within 4 days. 

What to serve this Sweet Potato Soup with?

This soup can be an awesome side dish or appetizer for any dinner or lunch – serve it beside any protein and vegetable to add some cozy deliciousness to your plate.

Want to turn it into a complete meal? I wilt in some extra greens and top it with shredded or chopped cooked chicken for more fibre and protein.  

MORE ABOUT THIS SWEET POTATO SOUP WITH PEANUT BUTTER AND KALE…

If soup was a love language, I think it’d be mine. 

There usually isn’t a week that goes by that I don’t have some sort of soup/stew/bowl-of-deliciousness simmering away on the stove (or in the Instant Pot!), especially in the wintery months. 

But I think what I love about soup is that the possibilities are endless and there are so many different variations and opportunities to make each pot unique or suited to what ingredients you have on hand. 

…AKA soups are really easy and no-fuss and super customizable to what you like and/or have on hand at any given time. 

Here are some substitutions or variations to try to make this soup your own: 

• Super Spicy: go heavier on the red pepper flakes or add cayenne pepper or some of your favourite hot sauce to the pot.
• More Veggies: wilt in an extra handful of greens or add some bell pepper.
• Toppings: top each bowl with extra lime, cilantro, chopped peanuts, red pepper flakes, a drizzle of full-fat coconut milk or shredded cooked chicken.

YUM!
