Soups & Stews
This sweet potato and sausage soup recipe delivers the perfect balance of smoky sausage, velvety sweet potatoes, and aromatic spices that warm your kitchen and soul. The secret lies in slow simmering, which allows flavors to meld into a rich, hearty broth that's as comforting as it is delicious.
I've perfected this recipe over years of testing, ensuring every spoonful is packed with deep, savory notes and just the right amount of sweetness.

Ingredients for sweet potato and sausage soup
Sweet, smoky, and packed with comforting flavors—this soup is all about that crispy celery top.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 lbs | Peeled and cubed, about 6 cups |
| Smoked Sausage 🌭 | 1 ½ lbs | Kielbasa or andouille, sliced into rounds |
| Celery Stems 🧅 | 4 whole | With leaves reserved for topping |
| Yellow Onions 🧅 | 2 whole | Thinly sliced, about 2 cups |
| Celery Leaves 🌿 | 1 cup | For crispy topping, chopped |
| Garlic Cloves 🧄 | 4 cloves | Minced for deep flavor |
| Paprika 🌶️ | 2 tbsp | Smoked variety for richness |
| Ground Cumin 🌿 | 1 tbsp | Toasted for warmth |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh |
| Chicken Broth 💧 | 6 cups | Low-sodium preferred |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For sautéing, fruity variety |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Heavy Cream 🥛 | ½ cup | Optional for richness |
The sausage is the star here—Kielbasa or andouille brings the perfect smoky depth, but any smoked sausage will work. Costco or Trader Joe's usually have great options at a good price. For the sweet potatoes, orange-fleshed, firm varieties hold up best during cooking. The celery leaves? Don't skip them—they add that addictive crunch on top. If you can't find fresh celery leaves, baby spinach or parsley work in a pinch, but nothing beats the real deal for that crispy texture.
No smoked sausage? Substitute with chicken sausage or even crispy bacon bits for a different flavor profile. The paprika is non-negotiable for that smoky flavor—Penzeys or Gourmet Garden have great smoked varieties. Running low on chicken broth? Vegetable broth works too, just add a splash of soy sauce for umami depth. The heavy cream is optional, but if you add it, full-fat gives the best richness. For a vegan version, swap the cream for coconut milk.
This soup tastes even better the next day—3-4 days in the fridge, sealed tightly. Freezes beautifully for up to 3 months—just thaw overnight in the fridge. I always make a double batch because it disappears fast. The celery leaves crisp up best when toasted fresh, so save those until serving. Store the broth and cooked ingredients separately if prepping ahead, then reheat gently to preserve that velvety texture.

Step-by-step instructions for sweet potato and sausage soup
This smoky, comforting soup delivers rich depth from the sausage and paprika while topping it with crispy celery leaves.
Sauté the Sausage and Aromatics
Heat the 0.5 cup extra-virgin olive oil in a large Dutch oven over medium heat. Add the 1.5 lbs smoked sausage in even slices and cook for 5-6 minutes, stirring occasionally, until the sausage releases its oils and begins to brown. This is where the deep, smoky flavor develops.
Remove the sausage with a slotted spoon and set aside. In the same pot, add the 2 whole yellow onions and 4 whole celery stems (chopped into ½-inch pieces). Cook for 5-7 minutes until the onions soften and become translucent. Add the 4 cloves garlic cloves and cook for 30 seconds until fragrant. The garlic should sizzle but not burn—this ensures a sweet, aromatic base.
Toast the Spices and Add Sweet Potatoes
Reduce the heat to medium-low and add the 2 tbsp paprika, 1 tbsp ground cumin, and 1 tsp dried thyme. Stir constantly for 1 minute until the spices release their aroma and the paprika deepens in color. This step builds the soup's signature smoky depth.
Add the 2 lbs sweet potatoes (cubed) and stir to coat evenly in the spiced oil. Pour in the 6 cups chicken broth and bring to a gentle boil. Once boiling, reduce the heat to low, cover, and let it simmer for 20-25 minutes until the sweet potatoes are fork-tender. You'll know they're ready when they collapse easily under gentle pressure.
Blend for Creamy Texture
Return the cooked sausage to the pot and stir to combine. Use an immersion blender to blend the soup until smooth and creamy. If you prefer a chunkier texture, blend only half the soup and leave the rest as-is. The soup should coat the back of a spoon with a velvety consistency.
Stir in the 0.5 cup heavy cream (if using) and season with 1.5 tsp salt and 0.5 tsp black pepper. Taste and adjust the seasoning—this is where the soup's balance comes together. The cream adds richness, but don't skip it if you prefer a lighter broth.
Prepare the Crispy Celery Topping
While the soup simmers, heat 1 tablespoon extra-virgin olive oil in a small skillet over medium-high heat. Add the 1 cup celery leaves and cook for 2-3 minutes until they wilt slightly and begin to crisp at the edges. This topping is the secret to adding texture and freshness.
Transfer the crispy celery leaves to a paper towel-lined plate to drain any excess oil. The leaves should be vibrant green with slightly crisp edges—this contrast elevates the soup's heartiness.
Serve with Crispy Topping
Ladle the soup into bowls and top each serving with the crispy celery leaves. The contrast of the warm, creamy soup with the cool, crispy topping makes every bite exciting. Serve immediately while the celery leaves are still crisp.
For extra depth, garnish with a sprinkle of paprika or a drizzle of the reserved sausage oil. This soup tastes even better the next day, so double the batch if you can—it's perfect for meal prep or sharing with friends.
Pro Tips For Making Sweet Potato And Sausage Soup
- CRISP THE SAUSAGE FIRST: Toss the sliced smoked sausage in a cold, dry skillet over medium-high heat—no need to wait for it to warm up. I learned this the hard way: rushing the sausage into a hot pot with onions just makes it greasy and unevenly browned. Let it render and crisp for 3-4 minutes first, then pull it out and set aside. That golden crust adds depth the soup desperately needs.
- PEEL AND CUBE POTATOES EVENLY: Sweet potatoes vary in size, and that’s a disaster for even cooking. Cut them into ½-inch cubes—no smaller, or they’ll turn to mush—and peel them just before cooking if you’re worried about browning. I skip this when I’m lazy, but the dish is noticeably better when every piece hits the same texture. (Pro move: Toss the cubes in a tiny bit of oil while they wait—keeps them from sticking.)
- SWEAT ONIONS AND CELERY LOW: Start onions and celery stems in the pot over medium-low heat—yes, even if you’re impatient like me. High heat burns them before they soften, and you’ll end up with bitter, charred bits. A good rule: If you’re sweating, not sizzling, you’re on the right track. This takes 8-10 minutes, but it’s the foundation for flavor. (Celery leaves? Save them for garnish—they add freshness at the end.)
- PUREE HALF THE SOUP: After simmering, blend about half the soup until smooth—don’t overdo it. This isn’t a puree; it’s just to thicken and round out the texture. I was skeptical until I tried it: the contrast of creamy and chunky makes every spoonful better. Use an immersion blender for ease, or transfer a ladleful to a regular blender, then stir it back in. (Skip this if you prefer rustic texture, but your future self will thank you.)
Flavor customization for sweet potato and sausage soup
Spice Level Boost
For a kick, add ½ tsp cayenne pepper when toasting the spices—it cuts through the sweetness beautifully. I like to balance it with 1 tsp honey stirred in at the end for a sweet-spicy contrast.
If you prefer heat, swap smoked sausage for spicy andouille and add 1 tsp hot sauce to the broth. 🌶️
Creamy Variations
Skip the heavy cream for a lighter version by stirring in ½ cup coconut milk after blending. For extra richness, try ¼ cup Greek yogurt instead—it adds tang without heaviness. If you love cheesy soups, fold in ½ cup shredded sharp cheddar at the end for a Southern-inspired twist.
Protein Swaps
Replace sausage with diced chicken thighs for a lighter option—just marinate them in 1 tbsp smoked paprika and 1 tsp garlic powder before cooking. For vegetarian, use crumbled tempeh or lentils (½ cup cooked) to mimic the meaty texture.
The celery leaves still add that perfect crunch to any version. 🥗
Sweetness Control
Reduce sweetness by roasting the sweet potatoes at 400°F for 20 minutes before adding to the soup—this caramelizes their natural sugars. For balance, add 1 tbsp apple cider vinegar to the broth.
If your sweet potatoes are extra sweet, increase the smoked paprika to 2.5 tbsp to deepen the savory notes.
Herb Infusions
Brighten the soup with 1 tbsp fresh rosemary when toasting the spices—it pairs wonderfully with the smoky flavors. For a Mediterranean twist, add 1 tsp dried oregano and finish with chopped fresh parsley.
If you love fresh herbs, stir in 2 tbsp chopped chives just before serving for a bright finish. ✨
Texture Twists
For extra heartiness, stir in ½ cup cooked quinoa or diced potatoes at the end. If you love crunch, toast ½ cup pepitas in a dry skillet until golden and sprinkle on top.
For a rustic touch, serve with crusty bread croutons—just toss cubes of baguette with 1 tbsp olive oil and ½ tsp garlic powder, then bake at 375°F for 8-10 minutes.

Frequently asked questions
Can I make this soup without an immersion blender?
Transfer about half the soup to a blender (don't fill past the halfway mark), blend until smooth, then return to the pot. For a rustic texture, leave some chunks unblended. Just be careful—hot soup creates steam pressure. Always vent the blender lid or use the tamper.
How do I adjust the recipe for a slow cooker?
Brown the sausage and sauté the onions/celery first in a skillet. Transfer everything to your slow cooker, add the broth and spices, then cook on low for 6-7 hours or high for 3-4 hours. Skip the initial simmer time—the slow cooker does all the work. Blend at the end for creaminess. The flavors develop even deeper this way!
What's the best way to reheat leftovers?
Gently reheat on the stove over medium-low heat until just warm (about 5-7 minutes). Stir frequently to prevent scorching. For microwave reheating, cover with a damp paper towel and heat in 30-second intervals, stirring between each. Never reheat to boiling—this can make the soup watery.
Can I use regular potatoes instead of sweet potatoes?
You can try, but the flavor and texture will be different. Regular potatoes will make the soup less sweet and more starchy. If you must substitute, use Yukon Gold potatoes (they hold up better) and add 1 tsp cinnamon to mimic sweet potato's natural sweetness. The celery topping still works beautifully!
Why does my soup taste too sweet?
Sweet potatoes naturally concentrate sweetness when cooked down. Balance it by adding ½ tsp apple cider vinegar or 1 tsp smoked paprika to deepen savory notes. For extra depth, stir in 1 tbsp tomato paste when sautéing the aromatics. The celery leaves' bitterness also helps cut sweetness when served on top.
