Italian Sausage and White Bean Soup takes me back to my grandmother’s farmhouse kitchen on cold winter evenings, where the smell of simmering sausage and herbs filled every corner of the house. She always said that the best soups are built in layers, starting with properly browned meat and ending with a splash of something bright to wake everything up.
In my Midwest kitchen, I’ve adapted her techniques into this hearty one-pot wonder that feeds a crowd without keeping me tied to the stove all evening. There’s something deeply satisfying about watching Italian sausage brown and release its flavorful oils, then building a soup around those rich flavors. The white beans add creaminess and protein, while the Tuscan kale wilts into tender ribbons that soak up the savory broth. I love how this Italian Sausage and White Bean Soup comes together in one pot, which means less cleanup and more time enjoying the meal with family. The secret ingredient is that splash of red wine vinegar at the end, something my grandmother taught me decades ago. It brightens all the flavors and makes this soup taste like you’ve been cooking all day. My grandchildren request this regularly during fall and winter months, especially when served with crusty bread for dunking. Your kitchen’s about to become the coziest room in the house.

Understanding Your Ingredients
Italian Sausage forms the flavorful foundation of this soup. In my kitchen, I prefer using a combination of mild and spicy sausage for complexity, though you can use chicken, turkey, or pork sausage based on preference.
Sweet Onion provides a mellow sweetness that balances the savory sausage and forms the aromatic base of the soup.
Carrots and Celery create the classic mirepoix foundation that adds depth and subtle sweetness to the broth.
Garlic brings essential savory notes that make Italian cooking so irresistible. I always use fresh minced garlic rather than jarred for the best flavor.
Italian Seasoning and Poultry Seasoning combine to create that signature Italian-American flavor profile with oregano, basil, thyme, and sage notes.
Flour thickens the broth slightly, creating a more substantial, stew-like consistency that coats the back of your spoon.
Gold Potatoes add heartiness and help make this a complete meal in a bowl. I prefer gold potatoes because their delicate skin is edible and their creamy texture holds up well in soup.
Chicken Broth forms the liquid base that carries all these flavors. I always choose low-sodium broth so I can control the seasoning myself.
White Beans contribute protein, fiber, and a creamy texture that makes this soup satisfying. You can use cannellini, great northern, navy, or small white beans interchangeably.
Heavy Cream adds richness and creates that silky texture that makes this soup feel restaurant-special.
Tuscan Kale wilts beautifully into the soup, adding nutrition and that classic Italian touch. Betty prefers Tuscan kale for its tender texture and mild flavor.
Red Wine Vinegar is the secret ingredient that brightens all the flavors at the end, cutting through the richness and making every spoonful more interesting.
Betty’s One-Pot Technique
Step 1. Betty always starts by heating a large soup pot or Dutch oven over medium-high heat, then adding the Italian sausage and breaking it up with a wooden spoon as it cooks. Once browned and fully cooked, remove it to a paper towel-lined plate, leaving behind 1-2 tablespoons of that flavorful grease.
Step 2. I’ve found that adding the onion, carrots, and celery to that rendered fat and sauteing for 4-6 minutes until softened builds incredible depth of flavor as the vegetables pick up all those browned bits from the bottom of the pot.
Step 3. After years of making this soup, I learned that adding the garlic and all the seasonings and stirring for about 60 seconds lets the spices bloom in the fat, enhancing their aroma and flavor significantly.
Step 4. Through trial and error, I learned that tossing in the flour and stirring to coat all the vegetables creates the base for a slightly thickened, more substantial broth.
Step 5. The key I discovered is adding the potatoes and chicken broth, bringing everything to a boil, then reducing to a simmer for 20 minutes until the broth thickens and the potatoes become fork-tender.
Step 6. My family prefers when I stir in the white beans, Tuscan kale, cream, and cooked sausage, letting the kale wilt down into tender ribbons that soak up all that delicious broth.
Step 7. Through trial and error, I learned that finishing with 2 tablespoons of red wine vinegar and adjusting the seasoning with salt and pepper creates that bright, balanced flavor that makes this Italian Sausage and White Bean Soup unforgettable.
Step 8. Betty always serves this hot with plenty of Parmesan cheese, fresh cracked pepper, chopped fresh herbs, and a hunk of crusty bread for dunking.
Keeping This Soup Fresh
I typically store leftovers in an airtight container in the refrigerator for up to 4 days. One thing I’ve noticed is that the potatoes absorb broth as it sits, so adding a splash of chicken broth when reheating brings it right back to life.
Betty’s freezing method works beautifully for this soup. Freeze it for up to 3 months in freezer-safe containers or bags, but wait to add the red wine vinegar until serving for the brightest flavor. The beans, sausage, and vegetables all freeze exceptionally well.
For the best texture, I reheat individual portions in the microwave for 2-3 minutes or warm the whole pot in a saucepan on the stovetop over medium heat, stirring occasionally. The flavors actually deepen overnight, making day-two bowls even more delicious than the first serving.

FAQs
Betty’s solution is swapping the sausage for plant-based sausage or an extra can of beans, and using vegetable broth instead of chicken broth for a completely vegetarian version.
Many home cooks find success with substituting fresh spinach, regular curly kale, or Swiss chard, though cooking times may vary slightly. Spinach wilts almost instantly.
I recommend soaking 1 cup dried beans overnight and cooking them until tender before adding to the soup. This takes extra time but gives you control over texture and reduces sodium.
