Why You’ll Love This Sausage Sweet Potato Soup
A cozy one-pot dinner for cool weather
There is something especially comforting about a pot of creamy soup simmering on the stove. This recipe combines sweet potatoes and Italian sausage, two ingredients that create a satisfying balance of sweet, savory, and lightly spicy flavors.
Everything cooks in one Dutch oven or large soup pot. You brown the sausage, sauté the vegetables and seasonings, simmer the sweet potatoes in broth, then finish the soup with greens and cream. That means less cleanup and a simple dinner with big flavor.
Sweet, savory, creamy, and satisfying
Sweet potatoes become tender and naturally creamy as they cook. Their mild sweetness pairs well with salty Italian sausage, smoky paprika, garlic, onion, and black pepper.
The addition of heavy cream makes the broth rich and smooth. Coconut milk also works well if you prefer a dairy-free option; it adds a subtle sweetness that complements the sweet potatoes. For the best balance, use full-fat canned coconut milk rather than the thin coconut beverage sold in cartons.
Easy enough for busy weeknights
This creamy sausage sweet potato soup takes about 45 minutes from start to finish, including chopping and simmering. To make it even faster, buy pre-diced sweet potatoes and pre-washed kale or spinach.
The recipe is also forgiving. If you have only spinach instead of kale, use spinach. If you have chicken broth instead of vegetable broth, use that. If you need a lighter soup, use turkey sausage and half-and-half instead of pork sausage and heavy cream.
Great for meal prep and freezer meals
This soup is excellent for meal prep because the flavor develops even more after a night in the refrigerator. Divide it into airtight containers for easy lunches or quick dinners during the week.
For food safety and best quality, refrigerate cooked soup promptly and use it within 3 to 4 days. Vegetable- or meat-added soups and stews can generally be frozen for about 2 to 3 months for best quality.foodsafety+1
Ingredients You’ll Need
Italian sausage: mild, hot, or turkey sausage
Italian sausage provides most of the savory flavor in this recipe. Mild Italian sausage creates a classic family-friendly soup, while hot Italian sausage brings extra spice. You can use pork sausage, chicken sausage, or turkey sausage.
If your sausage comes in casings, remove the casings before cooking. Crumble the sausage into small pieces as it browns so every bite has a little bit of savory meat.
Turkey sausage is a good lighter option, but it is usually less fatty than pork sausage. If you use turkey sausage, you may want to add an extra teaspoon of olive oil when sautéing the onion and garlic.
Sweet potatoes for natural sweetness and texture
Orange-fleshed sweet potatoes are the best choice for this creamy sausage sweet potato soup. Garnet and Jewel sweet potatoes are common options that become tender and creamy while holding their shape in the broth.
Peel the sweet potatoes and cut them into evenly sized cubes, about ¾ inch to 1 inch wide. Small, even cubes cook more quickly and ensure that every spoonful has tender pieces of sweet potato.
Do not cut them too small, or they may break apart completely during simmering. If you prefer a thicker soup, you can mash a few pieces against the side of the pot near the end of cooking.
Kale or spinach for a vegetable boost
Kale is sturdy and holds up well in hot soup. Remove the thick stems, then chop the leaves into bite-size pieces. Add kale during the final 5 to 7 minutes of simmering so it softens but still has a pleasant texture.
Baby spinach is another easy choice. It wilts very quickly, so stir it in only during the final 1 to 2 minutes of cooking. You can also use Swiss chard, but add it with the kale because it needs a little more time than spinach.
Chicken broth, garlic, cream, and seasonings
Chicken broth gives the soup a savory base, but vegetable broth works well if you prefer it. Use low-sodium broth so you can control the salt level, especially because Italian sausage can already be salty.
Garlic, onion, smoked paprika, dried thyme, and black pepper create warm, savory flavor. A small amount of red pepper flakes is optional but adds a gentle heat that pairs especially well with sweet potatoes and sausage.
Finish the soup with heavy cream for a traditional creamy texture, or use full-fat coconut milk for a dairy-free version. You can also use half-and-half for a lighter result, though the soup will be slightly less rich.
How to Make Creamy Sausage Sweet Potato Soup
Brown the Italian sausage
Heat a large Dutch oven or soup pot over medium-high heat. Add the Italian sausage and cook, breaking it apart with a wooden spoon, until browned and cooked through. This should take about 6 to 8 minutes.
If the sausage releases a large amount of grease, carefully spoon off some of it, leaving about 1 tablespoon in the pot. That remaining fat adds flavor and helps cook the onion and garlic.
If you use lean turkey sausage, the pot may look dry after browning. Add a teaspoon of olive oil before continuing to the next step.
Sauté the onion, garlic, and spices
Add the diced onion to the pot and cook for about 4 to 5 minutes, stirring occasionally, until soft and translucent. Add the minced garlic, smoked paprika, dried thyme, and red pepper flakes, if using.
Cook for about 30 seconds, stirring constantly. The spices should smell fragrant, but the garlic should not brown. This short step helps bloom the spices and gives the soup a fuller flavor.
Simmer sweet potatoes in chicken broth
Add the diced sweet potatoes to the pot. Pour in the chicken broth and use a wooden spoon to scrape up any browned sausage bits from the bottom of the pot. These browned bits add savory flavor to the broth.
Bring the soup to a gentle boil, then reduce the heat to medium-low. Cover the pot partially and simmer for 15 to 18 minutes, or until the sweet potatoes are tender when pierced with a fork.
For a thicker soup, use a potato masher to mash some of the sweet potatoes directly in the pot. You only need to mash a small portion; leave most cubes whole for texture.
Add cream and greens at the end
Once the sweet potatoes are tender, reduce the heat to low. Stir in the chopped kale and simmer for 5 to 7 minutes, until wilted and tender. If using spinach, add it during the last 1 to 2 minutes instead.
Pour in the heavy cream or full-fat coconut milk. Stir gently and warm the soup for 2 to 3 minutes. Do not bring it to a hard boil after adding cream or coconut milk.
Taste the soup and adjust with salt, black pepper, or additional red pepper flakes. Serve hot with grated Parmesan, fresh parsley, or crusty bread.
Tips, Variations, and Substitutions
Use coconut milk instead of heavy cream
Full-fat canned coconut milk is the best dairy-free substitute for heavy cream in this sausage sweet potato soup. It gives the soup body and creaminess without using dairy, and its subtle sweetness works naturally with sweet potatoes.
Shake the can before opening it so the thick coconut cream and liquid are combined. If you prefer a lighter coconut flavor, use half-and-half instead, or use ½ cup coconut milk plus ½ cup extra chicken broth.
Make it spicy with red pepper flakes
Hot Italian sausage is the easiest way to create a spicy soup. You can also add ¼ to ½ teaspoon red pepper flakes with the garlic and spices.
For a more smoky spice, add a pinch of cayenne pepper or a chopped chipotle pepper in adobo sauce. Start small, taste near the end, and add more heat only if needed. The spice becomes stronger as the soup sits.
How to thicken sweet potato soup
Sweet potatoes naturally thicken the broth as they cook. If you want a thicker, creamier soup, mash some of the cooked sweet potato cubes directly in the pot with a potato masher.
You can also use an immersion blender to blend a small portion of the soup. Blend for only a few seconds if you still want visible pieces of sausage and sweet potato. If your soup becomes too thick, add more broth a little at a time.
Use spinach if you do not have kale
Spinach is a quick and easy substitute for kale. Add it only during the last 1 to 2 minutes of cooking because it wilts almost immediately.
Swiss chard, collard greens, or finely chopped cabbage can also work. These sturdier greens need longer cooking time, so add them with the sweet potatoes or about 8 to 10 minutes before the soup is finished.
Serving, Storage, and FAQs
What to serve with sausage sweet potato soup
This creamy sausage sweet potato soup is filling on its own, but warm bread makes it even better. Serve it with sourdough, crusty French bread, garlic bread, cornbread, biscuits, or dinner rolls.
For a lighter side dish, try an arugula salad, kale salad, roasted Brussels sprouts, or a simple cucumber and tomato salad. A little grated Parmesan and fresh parsley on top of each bowl also adds a nice finishing touch.
How to refrigerate leftover soup
Let the soup cool slightly, then divide it into shallow airtight containers. Refrigerate it promptly rather than leaving it at room temperature for a long time.
Store leftover soup in the refrigerator for 3 to 4 days. Reheat it gently in a saucepan over medium-low heat, stirring occasionally. If it thickens after chilling, add a splash of chicken broth, milk, or water until it reaches your desired consistency.foodsafety+1
Can you freeze creamy sausage soup?
Yes, this sausage and sweet potato soup can be frozen. For best texture, freeze it before adding the heavy cream or coconut milk. Dairy can sometimes separate when frozen and reheated, although the soup will still be safe to eat if handled properly.
To freeze, cool the soup completely, place it in freezer-safe containers with a little space at the top, and freeze for up to 2 to 3 months for best quality. Thaw it overnight in the refrigerator, reheat gently, then stir in the cream or coconut milk before serving.foodsafety+1
Can you use regular potatoes instead of sweet potatoes?
Yes. Yukon Gold potatoes are the best regular potato substitute because they have a naturally creamy texture. Russet potatoes also work, but they break down more easily and will make the soup thicker.
Keep in mind that regular potatoes do not have the same natural sweetness as sweet potatoes. If you use them, the soup will taste more savory and less sweet. You can add extra carrots, a pinch of smoked paprika, or a little coconut milk to bring back some sweetness and depth.
