I started making this Sweet Potato Sausage Kale Soup Recipe on a random Tuesday when I needed dinner on the table fast, and now it’s become one of those recipes I turn to almost every week in the colder months.
There’s something about the sweetness of the potatoes against the savory sausage and slightly bitter kale that just works. I promise you don’t need any fancy skills to pull this off, just one big pot and about 40 minutes. Once you try it, I have a feeling it’ll earn a permanent spot in your rotation too.
Cooking Time
- Prep Time: 15 minutes
- Cooking Time: 30 minutes
- Total Time: 45 minutes
Ingredients
- 1 pound mild Italian chicken or turkey sausage, casings removed — a leaner option that still brings plenty of savory flavor
- 1 tablespoon olive oil — for browning the sausage and softening the aromatics
- 1 yellow onion, diced — builds the flavor base for the whole pot
- 4 cloves garlic, minced — fresh garlic makes a noticeable difference here over the jarred kind
- 1 pound sweet potatoes, peeled and cubed — pick firm, evenly sized potatoes so they cook at the same rate
- ½ teaspoon dried thyme — adds a warm, earthy note that pairs beautifully with sweet potato
- 6 cups chicken broth — use a low-sodium version so you can control the saltiness yourself
- 1 bunch kale, stems removed and leaves torn — strip the tough stems out or the soup turns bitter and chewy
- ¼ cup heavy cream or full-fat coconut milk — this is what gives the broth that silky, rich finish
- ½ teaspoon salt — adjust to taste depending on how salty your sausage and broth already are
- ½ teaspoon black pepper — freshly cracked makes a noticeable difference in flavor
Note: this recipe serves 6.
Equipment You Need
- Large stockpot or Dutch oven — gives you enough room to sauté, simmer, and stir without spilling
- Wooden spoon — perfect for breaking up the sausage as it browns
- Sharp knife and cutting board — makes quick work of dicing the onion and cubing the sweet potatoes
- Ladle — for portioning the soup neatly into bowls
- Blender or immersion blender (optional) — handy if you want to puree part of the soup for extra creaminess
How to Make Sweet Potato Sausage Kale Soup Recipe?
This soup comes together in one pot from start to finish, which is exactly why I love making it on busy weeknights. You’ll brown the sausage first, build out the broth, then finish everything with the kale and cream. Here’s the breakdown step by step.
Brown the Sausage
Heat the olive oil in your stockpot over medium heat, then add the sausage and break it apart with a wooden spoon. Cook until it’s no longer pink and has a bit of golden color on the edges, about 6 to 8 minutes. Once browned, transfer the sausage to a plate and set it aside for later.
Sauté the Aromatics
In the same pot, add the diced onion and cook until it turns soft and translucent, roughly 4 minutes. Stir in the minced garlic and thyme, cooking for another minute until fragrant. Don’t rush this step, since it’s what builds the soup’s flavor foundation.
Add the Sweet Potatoes and Broth
Pour in the chicken broth and add the cubed sweet potatoes, stirring everything together. Bring the pot to a gentle boil, then reduce the heat and let it simmer uncovered for about 15 minutes, until the potatoes turn fork-tender.
Stir in the Sausage and Kale
Return the browned sausage back into the pot along with the torn kale leaves. Let everything simmer together for another 5 minutes, just until the kale wilts down and turns a deep green color.
Finish with Cream and Season
Lower the heat and stir in the heavy cream or coconut milk, letting it warm through without boiling. Season with salt and pepper to taste, give it one final stir, then ladle it into bowls while it’s still hot.
Additional Tips for Making This Recipe Better
Here’s what I’ve picked up after making this soup more times than I can count.
- I always cut my sweet potatoes into small, even cubes so they finish cooking at the same time without turning mushy.
- I like browning the sausage a little longer than feels necessary, since those crispy edges add so much extra flavor to the broth.
- I never skip tasting before adding salt, because sausage and broth can already bring plenty on their own.
- I blend about a cup of the soup separately and stir it back in when I want a creamier texture without adding more dairy.
- I always add the kale at the very end so it stays vibrant instead of turning dull and overcooked.
Common Mistakes to Avoid
- I once left the kale stems in by accident, and they stayed tough and stringy even after a full simmer.
- I rushed the onion and garlic step one time, and the soup ended up tasting flat compared to my usual batch.
- I added the cream too early once and let it boil, which caused it to separate and look curdled.
- I cubed my sweet potatoes unevenly, so some pieces turned mushy while others stayed hard in the center.
- I forgot to taste and adjust the seasoning at the end, and the soup came out blander than I wanted.
How to Serve Sweet Potato Sausage Kale Soup?
I like ladling this into wide, shallow bowls so you can really see the color contrast between the orange sweet potato, deep green kale, and browned sausage. A sprinkle of freshly cracked pepper or a few red pepper flakes on top adds a nice finishing touch.
Pair it with a warm, crusty piece of bread for dipping, or set it out alongside a lighter bowl of something like a loaded cheddar potato soup if you’re feeding a hungrier crowd that wants options. A light drizzle of olive oil right before serving also makes the bowl look that much more inviting.
Variations
- Swap the heavy cream for full-fat coconut milk if you want a dairy-free, creamy sweet potato sausage soup
- Use baby spinach instead of kale for a milder, more delicate sweet potato sausage spinach soup
- Add a can of drained white beans for extra fiber and protein if you’re after a turkey sausage kale sweet potato and white bean soup
- Stir in a cup of cooked lentils for a heartier, plant-forward lentil sweet potato sausage soup
- Swap mild sausage for spicy Italian sausage if you want more heat in every bowl
- Finish with a splash of apple cider vinegar for a little brightness that cuts through the richness

Make Ahead and Storage
You can prep the sausage, onion, and sweet potatoes a day in advance and store them separately in the fridge so dinner comes together even faster.
Once cooked, store leftover soup in an airtight container in the refrigerator, where it stays fresh for up to 4 days.
For longer storage, freeze it in a sealed container for up to 3 months, though I’d recommend leaving out the cream until you reheat it for the best texture.

- It’s easy to customize: Whether you’re craving a sweet potato kale soup coconut milk version or want to bulk it up with beans or lentils, the base recipe flexes easily.
- It reheats beautifully: This is one of those soups that tastes even better the next day once the flavors have had time to settle.
- It balances nutrition and comfort: You get hearty protein from the sausage alongside fiber and vitamins from the sweet potato and kale, all in one cozy bowl.
FAQs
Can I make this a creamy sweet potato sausage soup without heavy cream?
Yes, full-fat coconut milk works great as a dairy-free substitute and still gives the broth that rich, silky texture.
What’s the best sausage to use for this sweet potato sausage soup recipe?
Mild Italian chicken or turkey sausage works wonderfully, though you can use spicy Italian sausage if you prefer extra heat.
Can I turn this into a sweet potato sausage soup smitten kitchen style version?
Absolutely, you can blend part of the soup smooth for a thicker, more rustic texture similar to that style while still keeping the sausage and kale chunky.
How long does leftover soup actually stay good in the fridge?
It stays fresh for up to 4 days when stored in an airtight container in the refrigerator.
Can I use spinach instead of kale in this sweet potato kale soup recipe?
Yes, baby spinach works well as a substitute and wilts down even faster than kale, so just add it in during the last couple of minutes of cooking.
If you’re building out a cozy soup rotation for the season, this one pairs nicely alongside something like a white cheddar chicken soup for nights when you want to offer a second, equally comforting option at the table.
