Whether you’re staring down a cold, gray afternoon and want something that warms you from the inside out, or you’re meal prepping on Sunday and need a lunch that actually holds you until dinner — this chicken sweet potato soup is the answer.
It’s a creamy, hearty soup with tender shredded chicken, sweet potato chunks, and kale in a velvety, garlicky broth that tastes like it simmered all day. It comes together in about 50 minutes, and it’s better on day two.
The trick is building the creaminess. Instead of heavy cream, this soup uses a combination of blended cottage cheese and a small amount of cream cheese stirred in at the very end. The result is a rich, velvety broth that tastes indulgent but delivers real protein instead of just fat.
The best part is that it’s genuinely better on day two. The flavors meld overnight, the sweet potatoes absorb more broth, and the whole thing thickens into something even more satisfying. Make it on Sunday, and you’ve got lunch or dinner handled through Wednesday.
Two things decide whether this turns out velvety or thin and separated, and neither is optional.
Brown the chicken first, then remove it. Searing the chicken builds a deeply savory flavor base that simmering raw chicken can’t replicate. The browned bits left in the pot become the foundation of the entire soup.
Add the dairy over low heat and never let it boil. Cottage cheese and cream cheese both separate when they hit a hard boil. Reduce the heat to low, stir the dairy in slowly, and warm it gently. This is the single most important step for a smooth, velvety finish.
Everything else is forgiving, flexible, and takes about 15 minutes of actual work.
Why This Recipe Works
Browning the chicken builds a real flavor foundation. Searing the chicken in the pot before adding liquid gives you deeply caramelized, savory flavor that becomes the backbone of the entire soup. Simmering raw chicken in broth tastes fine. Browning it first tastes like something you’d order at a restaurant.
Chicken thighs stay juicy and forgiving. Unlike breasts, thighs hold up through the two-stage simmer without drying out. They also add more flavor to the broth. If you prefer breasts, the recipe includes a note on how to adjust.
Tomato paste adds depth and umami. Cooking it with the spices for 1–2 minutes before adding liquid develops a deeper, richer flavor than simply dumping it into the broth.
Sweet potatoes add natural sweetness and body. As they simmer, they release starch that naturally thickens the broth. Their natural sweetness balances the savory chicken and garlic.
Blended cottage cheese replaces heavy cream with real protein. A cup of cottage cheese blended until completely smooth gives you the same creamy body as heavy cream with a fraction of the fat and about 24 grams of protein. Once it’s blended into the broth, nobody can tell it’s there.
A small amount of cream cheese gives you that velvety, chowder-like texture. Cottage cheese alone can be slightly grainy in a hot broth. A few ounces of cream cheese melted in at the end gives you a smoother, richer finish.
Kale adds substance without turning to mush. Lacinato kale holds its texture better than spinach and adds a slightly earthy flavor that balances the sweet potato. Add it at the very end so it stays bright green.
Lemon juice and Parmesan rind add depth and brightness. The Parmesan rind simmers in the broth and adds savory depth. A squeeze of lemon juice at the end brightens the whole pot and keeps it from tasting heavy.
It’s genuinely better on day two. The flavors meld overnight, the sweet potatoes absorb more broth, and the soup thickens slightly.
Creamy Chicken Sweet Potato Soup
This creamy Chicken Sweet Potato Soup is hearty, comforting, and packed with tender shredded chicken, sweet potatoes, and kale in a rich, garlicky broth. Instead of relying on heavy cream, the soup gets its creamy texture from blended cottage cheese and a small amount of cream cheese.
The result is a cozy, satisfying soup that's high in protein without tasting like a "healthy" substitute.
Ingredients
For the Soup:
- 1½ lbs boneless, skinless chicken thighs
- 1 tbsp olive oil
- 1 medium yellow onion, finely diced
- 3 celery stalks, diced
- 3 cloves garlic, minced
- 2 tbsp tomato paste
- 1 tsp smoked paprika
- 1 tsp dried thyme
- 1 tsp dried oregano
- ½ tsp red pepper flakes, optional
- 1½ tsp kosher salt, divided
- ½ tsp black pepper
- 6 cups low-sodium chicken broth
- 1 Parmesan rind, optional but recommended
- 2 medium sweet potatoes (about 1½ lbs total), peeled and cut into ½-inch cubes
- 1 bay leaf
- 3 cups chopped lacinato kale, stems removed
For the Creamy Finish:
- 1 cup 2% or full-fat cottage cheese
- 4 oz full-fat cream cheese, softened and cut into small cubes
- ½ cup whole milk
- 1 tbsp fresh lemon juice
For Serving:
- Fresh parsley, chopped.
- Freshly grated Parmesan
- Crusty bread, optional
Instructions
1. Brown the chicken. Pat the chicken thighs dry with paper towels. Season both sides with ½ teaspoon of kosher salt and black pepper.
Heat the olive oil in a large Dutch oven or heavy-bottomed soup pot over medium-high heat. Add the chicken in a single layer. If necessary, work in two batches rather than crowding the pot. Sear for 3–4 minutes per side, until nicely browned. The chicken does not need to be cooked through yet. Transfer it to a plate.
Don't worry if the chicken sticks slightly to the bottom of the pot. Those browned bits will add flavor to the soup.
2. Cook the vegetables. Reduce the heat to medium. Add the onion and celery to the same pot. Cook for 5–6 minutes, stirring occasionally, until the onion is translucent and the celery softens. Add the garlic and cook for 30 seconds.
3. Build the flavor base. Add the tomato paste, smoked paprika, thyme, oregano, red pepper flakes, and the remaining 1 teaspoon kosher salt. Cook for 1–2 minutes, stirring constantly. The tomato paste should darken slightly and coat the vegetables.
This short step matters because it develops deeper flavor than adding the tomato paste directly to the broth.
4. Add the broth and sweet potatoes. Slowly pour in the chicken broth while scraping the bottom of the pot with a wooden spoon. Add the Parmesan rind, bay leaf, and sweet potatoes. Bring the soup to a gentle simmer.
5. Simmer the chicken and sweet potatoes. Return the browned chicken and any juices from the plate to the pot. Reduce the heat to medium-low. Cover partially and simmer gently for 15–18 minutes, or until the thickest part of the chicken reaches 165°F on an instant-read thermometer. The sweet potatoes should be tender when pierced with a fork but should still hold their shape.
Don't rely on the cooking time alone to determine whether the chicken is done. Chicken pieces vary in thickness, so temperature is the reliable endpoint.
6. Remove and shred the chicken. Transfer the cooked chicken to a clean cutting board. Remove and discard the Parmesan rind and bay leaf. Let the chicken rest for a few minutes, then shred it into bite-sized pieces. Don't shred it too finely — larger pieces make the soup more satisfying.
7. Blend the cottage cheese. While the chicken rests, add the cottage cheese to a blender or food processor. Blend for 60–90 seconds, scraping down the sides once or twice if necessary. Continue blending until the cottage cheese is completely smooth and has the consistency of thick cream.
Don't skip this step. Blending is what prevents the soup from having noticeable cottage-cheese curds.
8. Temper the cream cheese. Place the softened cream cheese in a medium heatproof bowl. Ladle about ½ cup of the hot broth from the soup into the bowl. Whisk vigorously until the cream cheese is completely smooth. Add another ½ cup of broth and whisk again. This creates a smooth cream-cheese mixture that you can incorporate into the soup without large lumps.
9. Add the creamy finish. Reduce the soup to LOW heat. Slowly stir in the tempered cream cheese mixture. Then stir in the blended cottage cheese and milk. Heat gently for 2–3 minutes, stirring occasionally. Do not bring the soup to a hard boil after adding the dairy.
The soup should become noticeably creamy and slightly thicker. If it seems too thick, add ¼ cup more chicken broth at a time until it reaches your preferred consistency.
10. Add the kale and chicken. Return the shredded chicken to the pot. Add the chopped kale. Simmer gently for 2–3 minutes, just until the kale is tender and bright green. Turn off the heat.
11. Add the lemon juice and adjust. Stir in the fresh lemon juice. Taste the soup. If it tastes heavy, add another 1–2 teaspoons lemon juice. If it tastes flat, add a small pinch of salt. For more heat, add another pinch of red pepper flakes.
The lemon is important — it balances the richness of the creamy broth and makes the sweet potatoes taste sweeter without adding sugar.
12. Serve. Ladle the soup into bowls. Top with fresh parsley and a little freshly grated Parmesan. Serve with crusty bread if desired.
Notes
Protein per Serving: High-protein — about 28–32g depending on chicken and dairy brands
Nutrition note: Nutrition will vary depending on the chicken, cottage cheese, cream cheese, broth, and other ingredients used. For the most accurate nutrition information, calculate the recipe using your specific products.
Make-ahead: Cool leftovers promptly and transfer them to shallow airtight containers. Refrigerate and use within 3–4 days. When reheating, warm gently on the stovetop over medium-low heat, stirring occasionally. If the soup has thickened considerably, add a splash of chicken broth. For food safety, reheat leftovers to 165°F.
Freezer: For the best texture, freeze the soup before adding the creamy finish. Prepare the soup through the step where you shred the chicken, then cool it completely. Freeze the broth, vegetables, and chicken in airtight freezer-safe containers.
When ready to eat, thaw overnight in the refrigerator and reheat gently. Once hot, prepare and add the blended cottage cheese, tempered cream cheese, milk, and lemon juice as directed above. This gives you a smoother result than freezing and thawing the finished dairy-based soup.
Recipe Notes
The chicken. Chicken thighs are recommended because they stay more tender and forgiving during simmering than chicken breasts. If you prefer chicken breasts, use boneless, skinless breasts of similar total weight and begin checking their temperature earlier. Cook until the thickest part reaches 165°F.
The sweet potatoes. Cut them into approximately ½-inch cubes. Keep the pieces relatively small and uniform. Large pieces may remain firm while smaller pieces become overly soft.
Don’t boil the creamy soup. Once you add the cottage cheese and cream cheese, keep the heat low. A vigorous boil isn’t necessary and can make the finished soup look less smooth.
Suppose your soup is too thick. Add warm chicken broth ¼ cup at a time until you reach the desired consistency. The soup will thicken somewhat as it cools and as the sweet potatoes release more starch.
Suppose your soup is too thin. Don’t immediately add more dairy. Let the soup sit for 5–10 minutes first. If it’s still thinner than you’d like, simmer it gently uncovered for a few minutes before adding any additional dairy.
If the dairy separates, remove the pot from the heat immediately. Whisk in 2 tablespoons of warm broth until the soup comes back together. The soup will still taste good — it just may not look as glossy.
Tips for the Best Chicken Sweet Potato Soup
Brown the chicken first, then remove it. This is the single most important step for deep flavor. The browned bits left in the pot become the foundation of the entire soup.
Use chicken thighs, not breasts. Thighs stay juicy through the simmer and shred beautifully. Breasts work, but they dry out faster and add less flavor to the broth.
Don’t skip the tomato paste. It adds depth and umami that makes the soup taste slow-simmered instead of quick. Cooking it with the spices for one to two minutes blooms the flavor.
Add a Parmesan rind if you have one. It simmers in the broth and adds savory depth. This small step makes a noticeable difference. If you don’t have one, add an extra ¼ cup of grated Parmesan at the end.
Blend the cottage cheese completely smooth. Blend for a full 60–90 seconds in a food processor or blender. Any visible curds make the soup grainy.
Temper the cream cheese. Cold cream cheese dropped into hot broth curdles. Whisk it with a ladle of hot broth first, then stir it back into the pot. This is the most important step for a smooth, velvety finish.
Add the dairy over low heat and never let it boil. High heat is what causes dairy to separate. Low and slow is the way.
Cut the sweet potatoes into even ½-inch cubes. Uneven pieces cook unevenly. Large pieces stay firm while small pieces turn to mush.
Add the kale at the very end. Two to three minutes is enough to wilt it while keeping it bright green. Any longer and it turns gray and mushy.
Finish with lemon juice. A tablespoon brightens the whole pot and keeps the rich, creamy broth from tasting heavy. This is not optional.
Taste before serving and adjust. Balance salt, acid, and heat at the end. Taste and add more salt, lemon juice, or red pepper flakes as needed.
The soup thickens overnight. What looks brothy on day one will be thicker on day two. Add a splash of broth when reheating.

Frequently Asked Questions
How much protein is in each serving?
About 28–32 grams per serving, depending on whether you use chicken thighs or breasts and the specific dairy brands. Most of it comes from the chicken (about 22–26g per serving), with the rest from the cottage cheese and cream cheese.
Can I use chicken breasts instead of thighs?
Yes. Breasts are leaner but dry out faster. Use boneless, skinless breasts with a similar total weight, and start checking the temperature earlier. Cook until the thickest part reaches 165°F. About 30–34g protein per serving.
Can I make this without cottage cheese?
Yes. Use ½ cup of heavy cream instead. The soup will be richer, and the protein will drop to about 22–26g per serving.
Can I make this dairy-free?
Yes. Skip the cream cheese and use unsweetened coconut milk instead of the milk and cottage cheese. The soup will be less creamy but still good—about 24–28g protein per serving.
Why did my soup turn out grainy?
The cottage cheese wasn’t blended smooth enough, or the cream cheese curdled. Blend the cottage cheese for a full 60–90 seconds, temper the cream cheese with hot broth before adding it, and never let the soup boil after the dairy goes in.
Why did my soup turn out thin?
The sweet potatoes didn’t release enough starch, or you added too much broth. Simmer for 5 extra minutes to reduce, or blend half the soup with an immersion blender to thicken it.
Can I use frozen kale?
Yes. Add frozen kale during the last 5 minutes of cooking. The texture will be softer, but the flavor is still good.
Can I make this in an Instant Pot?
Yes. Brown the chicken using the sauté function, then add everything except the dairy and kale. Cook on high pressure for 10 minutes, then let it sit for a 10-minute natural release. Shred the chicken, then stir in the tempered cream cheese, blended cottage cheese, milk, and kale over low heat.
Is this recipe gluten-free?
Yes, as written, but check your broth, Parmesan rind, and any packaged ingredients to confirm.
Can I double this recipe?
Yes. Use a larger pot and double all ingredients. The cook time stays roughly the same.
How long does this last in the refrigerator?
Up to 3–4 days in an airtight container.
Can I eat this cold?
Yes, though it’s much better warm. The broth thickens significantly when cold.
