Tuscan White-Bean Soup With Chicken Sausage and Kale

When a pot of soup has tender beans, browned sausage, soft vegetables, and a broth thick enough to cling lightly to your spoon, it doesn’t need much else to feel like a complete dinner. This Tuscan White-Bean Soup With Chicken Sausage and Kale has that comforting, slow-cooked feel without keeping you at the stove all evening.

Cannellini beans make the broth naturally creamy, while Italian chicken sausage adds plenty of savory flavor. Kale gives the soup some freshness and texture, and a little lemon at the end keeps the whole pot from tasting too heavy.

The practical trick is simple: mash part of the beans before adding them. They thicken the broth beautifully without flour or heavy cream.

Ingredients

For the Soup

• 1 tbsp extra-virgin olive oil (15 mL)
• 1 lb mild Italian chicken sausage (454 g), raw, casings removed if using links
• 1 medium yellow onion, diced, about 1 cup (150 g)
• 2 medium carrots, peeled and diced, about 1 cup (130 g)
• 2 celery ribs, diced, about 3/4 cup (90 g)
• 4 garlic cloves, minced
• 2 tbsp tomato paste (33 g)
• 1 tsp dried Italian seasoning
• 1/4 tsp crushed red pepper flakes
• 1/2 tsp kosher salt, plus more to taste
• 1/2 tsp freshly ground black pepper
• 1 can (14.5 oz/411 g) diced tomatoes with their juices
• 6 cups low-sodium chicken broth (1.4 L)
• 2 cans (15 oz/425 g each) cannellini beans, drained and rinsed, about 3 cups or 500 g drained
• 5 packed cups chopped Tuscan or curly kale, tough stems removed, about 5 oz (140 g)

Cannellini beans work especially well because they’re creamy enough to mash into the broth while still holding their shape when left whole. Great Northern beans are a good alternative if that’s what you already have.

For Finishing

• 1 tbsp fresh lemon juice (15 mL)
• 1/3 cup finely grated Parmesan cheese, about 1 oz (30 g), plus more for serving if desired

Add the lemon and Parmesan after the soup finishes simmering. The lemon brightens the broth, while Parmesan adds savory depth without making the soup feel heavy.

How to Make This Recipe

Step 1: Brown the Chicken Sausage

Heat the olive oil in a 6-quart Dutch oven or large heavy-bottomed soup pot over medium-high heat. Add the chicken sausage and break it into small, bite-size crumbles with a wooden spoon. Cook for 6–8 minutes, stirring occasionally, until lightly browned with no pink remaining and the sausage reaches 165°F in the center.

Pro Tip: Give the sausage a little time against the hot surface before stirring. Moving it constantly prevents good browning and leaves fewer flavorful browned bits on the bottom of the pot.

Step 2: Cook the Vegetables

Add the onion, carrots, and celery to the sausage and reduce the heat to medium. Cook for 5–7 minutes, stirring occasionally, until the onion looks translucent and the carrots begin to soften around the edges. Stir in the garlic, tomato paste, Italian seasoning, red pepper flakes, salt, and black pepper. Cook for another minute.

Pro Tip: Let the tomato paste cook until it changes from bright red to a slightly deeper brick-red color. That short cooking time gives the broth a richer, less sharp tomato flavor.

Step 3: Add the Broth and Beans

Pour in the diced tomatoes and 5 1/2 cups of the chicken broth. Scrape the bottom of the pot with a wooden spoon to loosen the browned bits. Place 1 cup of the cannellini beans in a bowl with the remaining 1/2 cup broth and mash until mostly smooth. Stir the mashed beans and remaining whole beans into the soup.

This mashed-bean step is what gives the soup body. If all the beans go in whole, the broth will stay noticeably thinner.

Step 4: Simmer the Soup

Bring the soup to a gentle boil, then reduce the heat so it maintains a steady simmer. Cook uncovered for 12–15 minutes, stirring occasionally. The carrots should be easy to pierce with a fork, the whole beans should feel creamy inside, and the broth should lightly coat the back of a spoon.

Avoid letting the soup boil aggressively. A hard boil can break down the beans too quickly and leave the vegetables softer than you want.

Step 5: Add the Kale and Finish

Stir in the chopped kale and simmer for 5–7 minutes, until the leaves are tender but still have some texture. Turn off the heat, then stir in the lemon juice and Parmesan. Taste before adding more salt because the sausage, broth, and cheese already contribute seasoning.

Pro Tip: If the soup looks thicker than you like, stir in 1/4 to 1/2 cup extra chicken broth before serving.

Expert Tips for Better Results

• Use a heavy-bottomed Dutch oven or soup pot so the sausage and tomato paste brown evenly without scorching.
• Dice the carrots and celery fairly small, about 1/4 inch, so they become tender within the short simmering time.
• Rinse canned beans well before using them so the broth stays clean-tasting and you can control the salt more easily.
• Remove the thick kale stems before chopping because they take much longer to become tender than the leaves.
• Add the Parmesan after turning off the heat to help it melt smoothly into the broth.
• If the finished soup is thinner than you prefer, mash another 1/2 cup beans against the side of the pot and simmer for 2–3 more minutes.

Variations

• For more heat, use hot Italian chicken sausage and increase the crushed red pepper flakes to 1/2 tsp.
• Replace cannellini beans with two 15-oz cans of Great Northern beans using the same method.
• Use 5 oz baby spinach instead of kale, adding it during only the final 2–3 minutes of cooking.
• Add 1 tsp finely chopped fresh rosemary with the garlic and reduce the dried Italian seasoning to 1/2 tsp for a more herbal flavor.
• For a dairy-free version, omit the Parmesan and finish each bowl with a small drizzle of extra-virgin olive oil and a little extra lemon juice.

Serving Suggestions

• Serve with toasted sourdough or crusty Italian bread for soaking up the creamy bean broth.
• Pair the soup with a simple arugula salad dressed with lemon vinaigrette for a fresh contrast.
• Finish each bowl with freshly grated Parmesan and cracked black pepper.
• Add a small spoonful of basil pesto on top for an extra herbal note.
• Serve alongside sparkling water with lemon or unsweetened iced tea for an easy weeknight meal.

Storage and Reheating

• Refrigerator: Cool the soup promptly and store it in an airtight container for up to 3–4 days.
• Freezer: Freeze in individual portions or freezer-safe containers for up to 2–3 months.
• Thawing: Thaw overnight in the refrigerator for the most even texture.
• Stovetop: Reheat over medium-low heat for 5–8 minutes, stirring occasionally, until steaming hot and reaching 165°F.
• Microwave: Heat individual portions in 60–90 second intervals, stirring between each interval until evenly hot.
• If the soup thickens in storage, stir in a splash of chicken broth or water while reheating.
