A bowl of Italian Sausage Potato Soup with Kale is pure comfort: warm, filling, and easy to make on a busy evening. I love how the potatoes soften in the savory broth while the sausage gives each spoonful a rich, satisfying flavor. It feels special enough to share with family, yet simple enough for an ordinary weeknight.
This soup brings together mild Italian sausage, russet potatoes, chopped onion, garlic, and tender kale. Beef broth makes a deep, savory base, while half-and-half adds a gentle creaminess. Dry white wine, Italian seasoning, bay leaf, black pepper, and a pinch of red pepper flakes round out the flavor with warmth and just a little kick.
The method is straightforward: brown the sausage, soften the vegetables and seasonings, then add the wine and broth. After the potatoes turn tender, take the pot off the heat and stir in the dairy. From start to finish, the soup takes about 30 minutes, and the recipe serves 6. The wine is an ingredient in this recipe, so it is intended for adults 21 and older.
Serve Italian Sausage Potato Soup with Kale on a chilly night, or make it for a casual lunch with friends. It also works well for a potluck or family dinner, especially with bread on the side. Since it reheats easily, you can enjoy a bowl the next day, too.

Italian Sausage Tips
For the best flavor in Italian Sausage Potato Soup with Kale, choose fresh mild Italian sausage from the refrigerated meat section. Mild sausage gives the broth a savory, herby taste without making the soup too spicy. If you prefer extra heat, use hot Italian sausage or keep the mild sausage and add a little more red pepper flakes. Remove sausage casings if needed, then break the meat into small pieces as it browns. Cook it through before adding the vegetables, and drain off excess fat if the pot looks greasy.
Options for Substitutions
- Sausage: Use hot Italian sausage for more heat, or choose chicken or turkey Italian sausage for a leaner option. Cooking time may vary slightly, so make sure the meat is fully cooked.
- Potatoes: Yukon Gold potatoes can replace russets. They hold their shape well and have a naturally creamy texture.
- Kale: Swap in chopped Swiss chard or spinach. Add spinach near the end, since it wilts much faster than kale.
- Broth: Use chicken stock instead of beef broth for a milder soup. Choose low-sodium broth if you want more control over the salt.
- Dairy: Use milk instead of half-and-half for a lighter finish. For a dairy-free version, try an unsweetened, plain plant-based cooking alternative, though the flavor and texture may differ.
- Wine and herbs: If you do not want to cook with wine, leave it out and use a splash of extra broth to loosen the browned bits. You can also use dried thyme in place of some Italian seasoning.
Watch Out for These Mistakes
First, do not rush browning the sausage. Give it enough time to cook and develop golden bits on the bottom of the pot. Those browned bits add flavor when you pour in the wine. If the sausage releases a lot of fat, spoon out the extra before adding the vegetables.
Next, cut the potatoes into similar-sized pieces. If some chunks are much larger than others, the small ones may fall apart before the large ones turn tender. Check them with a fork as they cook, and avoid boiling the soup longer than needed.
Also, add the dairy after you take the pot off the heat. Boiling the soup after adding half-and-half or milk can make the dairy separate or affect the smooth texture. Stir it in gently once the potatoes are ready.
Finally, taste before adding extra salt. Sausage and broth can both contain plenty of sodium, so the recipe’s teaspoon may be more than you need with some brands. Start with the listed amount, then adjust at the end. Because this soup contains wine, serve it only to adults 21 and older.
What to Serve With Italian Sausage Potato Soup with Kale?
Italian Sausage Potato Soup with Kale pairs well with warm crusty bread or garlic toast for dipping. For a fresh contrast, serve it with a simple green salad dressed with lemon or vinaigrette. Roasted vegetables, such as carrots or green beans, also make a nice side. If you are serving a crowd, set out bread and salad so everyone can build a satisfying bowl-and-sides meal.
Storage Instructions
Store: Let the soup cool, then transfer it to an airtight container and refrigerate it within two hours of cooking. Enjoy it within 3 to 4 days. The potatoes may soften a little as they sit, but the flavor remains satisfying.
Freeze: For the best texture, freeze the soup before adding the half-and-half or milk, since dairy can separate after freezing and thawing. Store it in a freezer-safe container for up to 2 to 3 months, leaving a little space at the top for expansion. Thaw it overnight in the refrigerator, reheat it, then stir in the dairy off the heat.
Reheat: Warm individual portions in the microwave in a microwave-safe bowl, stirring partway through, until steaming hot. To reheat a larger amount, place it in a saucepan over medium-low heat and stir often. Avoid a hard boil, especially if the soup already contains dairy.

Ingredients
- 1/2 lb mild Italian sausage
- 1 onion, chopped
- 2 russet potatoes, peeled and diced
- 2 garlic cloves, minced
- 1 bunch kale, stems removed, leaves chopped bite-sized
- 4 cups beef broth (chicken stock also works)
- 1/2 cup half-and-half or milk
- 1 bay leaf
- 1 tsp Italian seasoning
- 1 tsp salt
- 1/2 tsp black pepper
- Pinch of red pepper flakes
- 1/4 cup dry white wine (Chardonnay suggested)
Step-by-Step Instructions
Step 1: Brown the Sausage and Prep the Vegetables
For adults 21 and older: This recipe contains alcohol and is intended for guests of legal drinking age. Set a large stockpot over medium heat and add the sausage. Break it into small pieces as it cooks. While it browns, peel and dice the potatoes, chop the onion, mince the garlic, and remove the kale stems before chopping the leaves into bite-sized pieces.
Step 2: Soften the Vegetables and Seasonings
Once the sausage is cooked through, add the onion and potatoes to the pot. Stir in the bay leaf, Italian seasoning, salt, black pepper, and red pepper flakes. Cook until the vegetables just begin to soften, stirring now and then. Then add the kale and cook for another 1 to 2 minutes, until it starts to wilt.
Step 3: Add the Wine
Pour in the dry white wine. Use a spoon to scrape the browned bits from the bottom of the pot and stir them into the vegetables. This step brings the savory flavor left by the sausage into the soup. If you are avoiding wine, use a splash of extra broth instead.
Step 4: Add Broth and Cook the Potatoes
Turn the heat to high and pour in the broth. Bring the soup to a boil, then keep it uncovered until the potatoes are fork-tender. Start checking after several minutes, since the cooking time depends on the size of the potato pieces and how strongly the soup is boiling.
Step 5: Finish With Dairy and Serve
Take the pot off the heat and remove the bay leaf. Stir in the half-and-half or milk until the soup looks creamy. For a richer finish, stir in a tablespoon of butter. Taste and adjust the seasoning, then ladle the soup into bowls and serve warm.
Conclusion
Italian Sausage Potato Soup with Kale is a quick, cozy meal made with savory sausage, tender potatoes, and greens in a flavorful broth. It takes about 30 minutes, serves 6, and is easy to adapt with chicken stock, spinach, or a different dairy option. Because it includes wine, serve it only to adults 21 and older. Give this soup a try on your next chilly evening, and share how it turned out or which variation you enjoyed.
