This hearty Mexican sweet potato chicken soup is loaded with veggies, lean protein and has a smoky, sweet flavor from dried guajillo Mexican peppers.
Okay, I’m going to come right out and admit something I’m kind of embarrassed about… cooking with dried peppers has always intimated me. I used to walk past them in the store and think, what the heck do people do with those things? This is naive, but I honestly thought that all dried peppers were super spicy and I had no clue how I could use them in my cooking.

How to Cook With Dried Peppers
It wasn’t until I attended a cooking demo during a yoga retreat at the Veritas Farmhouse where the chef used dried guajillo Mexican peppers in a creamy sweet potato soup that I realized they’re actually pretty easy to work with and they’re awesome for adding a unique depth of flavor and spice.
I’d never heard of guajillo Mexican peppers before, but I quickly learned that they are one of the most popular chiles used in Mexican cuisine. They’re a little on the sweeter side with a hint of tang (similar to a cranberry) and a mild smokiness. I wouldn’t consider these peppers spicy so if you’re not a huge fan of spicy foods this would likely be a good pepper to test out.
After trying the amazing soup at the retreat I decided it was officially time to conquer my unnecessary fear of cooking with dried peppers at home and ordered a bag of guajillo Mexican peppers. I remade the sweet potato soup that we had at the retreat, which was thick, rich and oh so creamy.
We enjoyed it, but I wanted to experiment with making a chunky soup with more veggies and protein so that it could be eaten as a meal. And that’s how this Mexican sweet potato soup with cauliflower, spinach and chicken came to be.

Why Eat Dried Peppers
If you’re like me and haven’t really experimented with dried peppers before I highly recommend grabbing a bag and hopping to it. They’re such a great way to add a ton of flavor and spice to a dish without adding a ton of extra calories! Plus, despite their burning taste, chili peppers have long been considered a healthy spice. They are very high in antioxidant carotenoids and rich in various vitamins and minerals (Vitamin C, Vitamin B6, Potassium and Vitamin A). Studies have even shown that chili peppers can help with pain relief and promote weight loss by reducing appetite and increasing fat burning. (Source)

Sweet Potato Chicken Soup Ingredients
- chicken breast – boneless, skinless chicken breast is seasoned and chopped into cubes for this soup.
- vegetables – yellow onion, garlic, sweet potato, baby spinach, cauliflower.
- guajillo Mexican peppers – I got mine from nuts.com!
- chicken broth – the liquid base of this soup, provides tons of flavor! You can also use vegetable broth.
- olive oil – to simmer the chili pepper puree and vegetables in.
- seasonings and spices – dried oregano, sea salt, ground pepper, cumin and cloves.
- optional toppings – avocado, radishes, cilantro, lime, etc.

How to Make Sweet Potato Chicken Soup
Season Chicken – Season chicken with oregano, 1 teaspoon sea salt and black pepper. Cut into cubes and set aside.
Rehydrate peppers – Remove the stems and dump out all the seeds from inside the peppers. Place the peppers in a saucepan with water. Bring them to a boil and simmer for about 10 minutes or until they’ve softened. That’s it! At this point they’re rehydrated and ready to be used! Be sure to save the water for the next step.
Blend – Add peppers and ¾ cup water from the saucepan into a high-powered blender. Add onion, garlic, cumin, cloves and ½ teaspoon salt and then blend until smooth.
Simmer – Add oil to a large saucepan on medium heat. Add chili pepper purée into the pan and reduce heat to medium-low. Cook, uncovered, stirring frequently, until thickened, about 10 minutes. Add broth, seasoned chicken cubes, sweet potato and cauliflower into the saucepan. Cover and simmer until chicken is tender and cooked through and sweet potatoes are fully cooked, this should take about 10-15 minutes. Stir in baby spinach until wilted and season with additional salt, if needed.
Serve – Portion soup into bowls and top with toppings of choice. I love serving mine with avocado, sliced radishes, cilantro and a lime wedge for squeezing over the top.

How to Serve Soup
This soup is a hearty enough recipe to be a meal in one! Having said that, I love eating it with my pumpkin cornbread muffins. It’s also delicious served with bread, crackers (I love my almond crackers) or even tortilla chips. It can also be served with a salad… I have a ton of salad recipes to choose from, but something light and fresh like this garlicky kale salad would be perfect.
How to Store Leftovers
Let the soup cool completely before transferring to an airtight container. Store in your refrigerator for up to 5 days. If you need to store it longer, let the soup cool completely in the fridge and then transfer to the freezer for up to 3 months.

Dried peppers can sometimes be a little dusty. I like to clean them before using them, especially if you use the soaking water as you do in this recipe. I sometimes wipe them with a damp cloth. If they are really dirty I rinse them in cold water after de-stemming, de-seeding, and de-veining them i(f you want them to be a little more mild, since a lot of the heat is in the seeds and veins). Rather than boiling the peppers, I pour boiling water over them and cover them until they soften. I think this prevents some loss of flavor. This soup sounds yummy, and the sweet potato and cauliflower are unique additions.
This soup looks amazing. I don’t like soup too spicy so these peppers sound perfect. Can’t wait to try it. Thanks for sharing.
I tried it and it’s delishes! I made a few modifications… I was trying to see if sweet potatoes could be used in a “caldo de pollo”. My mom is diabetic and am trying to find authentic Mexican recipes without so much of the carbs and starch. I knew sweet potatoes are a good super food. Instead of canned broth I cooked a chicken breast with bone in skinless. My mom insists the bone and skin give it the rich flavor but since we are health conscious now we compromised with skinless and bone in. I timed so as the chicken cooked I was able to add the veggies and the Chile purée to the pot. In addition to sweet potatoes, cauliflower, and spinach I also added chayote which is a type of squash that you normally find in authentic Mexican chicken soup (caldo de pollo). And also threw in Mexican squash. It’s like zucchini just lighter green and spotted and fatter. And I threw in the cilantro sprigs like normally with a caldo de pollo in the last 5 minutes of cooking. That cilantro cooked with the soup gives it that awesome home made flavor and scent. Mmmmm…. next time I’ll be straining the Chile purée through a hand colander to get rid of the skin. I do that when I make the purée I just don’t know why I skipped this time. And for garnish I’ll use the next time some thin sliced raw cabbage. The lime is a great addition too as it counters the sweetness of the potatoes and the avocado adds that nice creamy texture. Great recipe! I’ll definitely be adding this to the familia recipes at Casa Olvera. Thumbs up!
I am looking forward to trying this recipe. Has anyone tried using ground guajillo Chilis? I am.having a difficult time finding them in the full dried form. Thanks!
Hi, what substitute would you recommend for the chicken if you wanted the soup to be vegetarian?
Hi Britt – You could just add more veggies of your choice or chickpeas if you’re looking for something with a little protein. Let me know if you try it and how it turns out.
Do you have any recommendations for trying this in a crockpot with ground chicken?
Hey Lindsey! I haven’t made this in the crockpot before, but I’m sure it would work! Let me know if you end up trying it.
I made this for dinner tonight and it was absolutely delightful!
I had some butternut squash I had to use up and some left over black beans that I threw in the pot too! I think this can work as a great “clear out the fridge” soup.
I also added half a jalapeño to the pepper purée, because I like a bit of heat.
Looking forward to the leftovers and dropping off some for my dad on the way to work tomorrow!
So glad you enjoyed this soup, Kariee!! Thanks for making it and for coming back to leave a review. I so appreciate it. 🙂
I’ve tried a few of your recipes so far. We’ve enjoyed them all. I couldn’t make it to the hispanic market in time, so I used a few chipotles in adobo sauce. I’m excited to try it as written, but the way it came out was amazing! I’m not much of a soup person, but I loved every bite of this one. If you don’t mind dairy, a dollop of sour cream will make it out of bounds!
Yay!! So glad you loved this soup, Nick. Thanks for coming back to leave a review. I so appreciate it!
Hi! I was led here by your other post that suggests swapping out the cauliflower for broccoli stems (looking for ways to use up broccoli stems). It sounds like cauliflower would be great in this Mexican soup. Have you tried it with broccoli? They have such a different taste that I want to be sure it would substitute well.
Thanks so much.
I haven’t tried broccoli in this soup, but I bet it would work just fine!! You’ll have to come back and let me know if you try it. 🙂
I love this recipe, very flavorful and easy to make. I’m having a friend over for dinner and this is what I’m making, so good.
Woo! Happy to hear you’re a fan of this recipe, Peggy! Thanks for the review. I really appreciate it!
