Sweet potatoes are the heart of this soup, so grab the orange-fleshed ones—they're sweeter and creamier than the white varieties. Trader Joe's and Whole Foods usually carry the best ones, but any grocery store's produce section works. Look for firm, heavy potatoes with no soft spots. The bell peppers add color and natural sweetness—mix up red, yellow, and orange for the prettiest bowl. Roasting them first concentrates their flavor and gives that smoky depth the recipe promises. Don't skip this step—it's what makes this soup sing!
No smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close, though it won't be identical. Swapping bell peppers? Zucchini or butternut squash work in a pinch, but they change the texture. The coconut milk adds richness, but Greek yogurt or cashew cream are great dairy-free alternatives. Fresh thyme is ideal, but dried works at one-third the amount if that's what you've got. And if you're watching calories, use low-fat coconut milk—just know it won't be as creamy. The fire-roasted tomatoes? Muir Glen brand is my go-to—they're always in stock and taste amazing.
This soup tastes even better the next day as flavors meld together. Store it in an airtight container in the fridge for up to 5 days. For leftovers, I like to portion it into jars with a dollop of sour cream on top—just pop them in the microwave for 2-3 minutes to reheat. Freezing isn't recommended since the texture changes, but you can freeze the broth separately for up to 3 months if you want to make fresh soup later. The aromatics—onion, garlic, and thyme—can be prepped ahead and stored in the fridge for 3 days to save time on cooking day.

Step-by-step instructions for sweet potato and pepper soup
This smoky-spiced soup comes together in one pot with velvety richness—let's make it happen!
🔥 Step 1: Sauté the Aromatics Until Fragrant
Heat the 0.25 cup olive oil in a large pot over medium-high heat. Add the diced yellow onion and cook for 3-4 minutes until softened and translucent. Here's the thing—you want the onion to caramelize just slightly at the edges, but not brown.
Next, add the 4 minced garlic cloves and stir for 30 seconds until fragrant. That garlic aroma should fill your kitchen—this is where the soup builds its flavor foundation. Immediately add the 1 tbsp smoked paprika, 1 tsp ground cumin, 1 tsp salt, and 0.5 tsp black pepper. Stir constantly for 10 seconds to toast the spices and release their aromas—this prevents bitterness and deepens the smoky flavor.
🍳 Step 2: Roast the Sweet Potatoes and Bell Peppers
While the aromatics cook, cut the 2 lb sweet potatoes into 1-inch cubes and halve the 3 whole bell peppers lengthwise, removing stems and seeds. Toss them together on a large baking sheet with 1 tablespoon olive oil (reserve the rest for later), 0.5 tsp salt, and 0.25 tsp black pepper.
Roast at 425°F for 25-30 minutes until the sweet potatoes are tender when pierced with a knife and the bell peppers are blistered and charred in spots. You'll know they're perfect when the sweet potatoes yield slightly to pressure and the peppers have deepened in color. This roasting step caramelizes the natural sugars, creating that velvety texture we're after.
🥘 Step 3: Simmer the Soup Base
Transfer the roasted sweet potatoes and bell peppers to the pot with the sautéed aromatics. Add the 14.5 oz canned diced tomatoes and 4 cups vegetable broth. Bring to a boil, then reduce heat to medium-low and let it simmer uncovered for 15-20 minutes until the sweet potatoes are completely tender and the flavors meld.
Use an immersion blender to purée the soup directly in the pot until completely smooth—this keeps everything contained and makes cleanup easier. If you prefer texture, leave about ⅓ of the mixture unblended. Taste and adjust seasoning with more salt or pepper if needed. The soup should have a rich, smoky depth with sweetness from the roasted vegetables.
🔥 Step 4: Finish with Creamy Richness
Reduce heat to low and stir in the 0.5 cup coconut milk and 1 tbsp chopped fresh thyme. Simmer gently for 2-3 minutes—just enough to warm through without curdling the coconut milk. The soup should be silky and have a beautiful sheen from the coconut milk.
For serving, ladle the soup into bowls and top each with a dollop of 0.25 cup sour cream. The contrast of cool sour cream against the warm soup is what makes this dish truly special. Garnish with a sprinkle of smoked paprika for that final smoky touch. Serve immediately while hot—this soup tastes even better the next day, but the texture is best fresh!
Pro Tips For Making Sweet Potato And Pepper Soup
- CHAR THE ONION FIRST: I learned this the hard way—if you toss raw onion into the pot with sweet potatoes, you’ll end up with chunks of tough, undercooked onion floating in your soup. Sauté it in oil until it’s translucent and just starting to caramelize (about 5 minutes) before adding anything else. The flavor becomes deeper, and it blends into the soup instead of sitting like a mystery.
- PEEL SWEET POTATOES AFTER COOKING: Peeling raw sweet potatoes is a mess, and you’ll lose more flesh than you keep. Roast or boil them whole first, then cool slightly before peeling under running water. The skins slide off effortlessly, and you won’t waste half the potato in the trash.
- SIMMER NOT BOIL: This soup is forgiving, but if you let it boil hard, the sweet potatoes turn to mush and the peppers lose their bright color. Keep the heat at a gentle simmer—you should see tiny bubbles breaking the surface, not a rolling, aggressive boil. It’ll take 10-15 minutes longer, but the texture stays creamy and the flavors stay balanced.
- USE ROASTED PEPPERS: Fresh peppers work fine, but roasted bell peppers (jarred or homemade) add a smoky depth that changes the game. Toss a handful into the pot with the tomatoes, and you’ll get that restaurant-quality richness without extra effort. If you’re short on time, just drain them well—no need to rinse.
Storing and reheating your leftovers
Refrigerator Storage
Let your soup cool to room temperature for no more than 2 hours before transferring it to an airtight container—I love using Ball mason jars for portion control. Store it in the fridge at 40°F or below for up to 5 days.
The flavors actually intensify as the spices meld together, making it even more comforting the next day. Just give it a quick stir before reheating to redistribute any settled ingredients. 💫
Freezer-Friendly Broth
While the full soup doesn't freeze well (the texture changes), you can save the broth separately for up to 3 months. Strain out any solids and freeze the liquid in quart-sized freezer bags with 1 inch headspace for expansion.
When ready to use, thaw overnight in the fridge and use it as a base for fresh soup or other recipes. This is my go-to trick for making future batches even easier. ❄️
Stovetop Reheating
For the best texture, reheat your soup on the stovetop over medium-low heat. Pour it into a pot and add 2-3 tablespoons of water or broth to prevent sticking. Heat gently for 10-15 minutes, stirring occasionally, until it reaches 165°F.
The low heat prevents scorching while bringing out those deep, smoky flavors. Taste and adjust seasoning—you might need a pinch more salt after reheating. 🔥
Microwave Method
When you're in a hurry, the microwave works in a pinch. Transfer a single serving to a microwave-safe bowl and cover loosely with a microwave-safe lid or damp paper towel. Heat on medium power (50%) for 2-3 minutes, stirring halfway through.
If the soup looks thick, add 1 tablespoon of water or broth and stir well. This method is fastest but can make the soup slightly watery—just stir in a dollop of sour cream to restore creaminess. ⏱️
Garnish Refresh
Before serving reheated soup, always add fresh garnishes to brighten the flavors. A dollop of sour cream, a sprinkle of smoked paprika, or a few chopped fresh thyme leaves make all the difference.
I also like adding a swirl of olive oil on top—it adds richness and helps restore that restaurant-quality sheen. Presentation matters, even for leftovers! ✨
Meal Prep Tips
Prep ahead by roasting the sweet potatoes and peppers in advance and storing them separately in the fridge for up to 3 days. Keep the sautéed aromatics in a sealed container too. When you're ready to cook, just combine everything in the pot and simmer.
This cuts your active cooking time by nearly half—perfect for busy weeknights. The extra effort makes the leftovers taste even more rewarding! 💡

Frequently asked questions
Can I make this soup without roasting the sweet potatoes and peppers?
You can, but you'll miss the caramelized depth that makes this soup special. If you're short on time, sauté them in the pot with the onions for 10-12 minutes until tender. The flavor will be good, but less rich and complex than the roasted version. For best results, stick with the roasting method—it's what creates that velvety texture and smoky aroma.
What if I don't have smoked paprika?
No problem! Use regular paprika plus ½ teaspoon liquid smoke for a similar effect. If you can't find liquid smoke, try ½ teaspoon chipotle powder or 1-2 dashes of hot sauce to add a smoky kick. Just remember that these substitutes will change the flavor slightly—smoked paprika gives the most authentic depth.
How can I make this soup spicier?
Add ½ teaspoon cayenne pepper or 1 teaspoon hot sauce during the simmering step. For extra heat, stir in 1 minced jalapeño with the aromatics. If you like it really spicy, roast the jalapeño with the sweet potatoes and peppers. Always taste before serving—you can adjust the heat level to your preference.
Can I use regular potatoes instead of sweet potatoes?
Regular potatoes will work, but they won't give the same sweet, creamy texture. If you must substitute, use Yukon Gold potatoes—they're waxy and hold up better than russets. The soup will be less rich and more starchy, but still delicious. For the best flavor, stick with sweet potatoes—they're what make this soup uniquely comforting.
Is this soup kid-friendly?
Yes, but with adjustments! For little ones, skip the smoked paprika and reduce the cayenne. The natural sweetness of the roasted sweet potatoes and peppers makes this soup naturally appealing. Serve it with a side of buttered noodles or toasted bread to make it even more kid-friendly. You can also blend it extra smooth to avoid any texture issues.
