Rustic Tuscan-Style Sausage, White Bean, and Kale Soup

Start with a warm bowl, a crusty cheesy bite, and a feeling that you somehow unlocked a cozy little corner of Tuscany in your own kitchen. Sound good? I thought so. I first made this Rustic Tuscan-Style Sausage, White Bean, and Kale Soup on a rainy Sunday when I felt dramatic and hungry—turns out drama and hunger pair well with sausage and beans. Want something comforting that still feels kind of fancy? This is it. If you love garlicky greens, you’ll appreciate the vibe—here’s a similar take that I turn to when I want fewer carbs: garlicky sautéed swiss chard and white beans.

Why You’ll Love This Recipe

• Super comforting — the sausage, beans, and kale create a satisfying, stick-to-your-ribs bowl.
• Budget-friendly — beans and kale stretch the sausage so one pound feeds a crowd.
• Make-ahead magic — the soup tastes even better the next day, FYI.
• Versatile — you can swap sausage types, beans, or greens and still win.
• Quick-ish — it simmers mostly unattended, so you can do life while it cooks.

Ingredients You’ll Need

Ingredient

• 2 tablespoons olive oil
• 1 pound Italian sweet sausage, casing removed
• 1 medium onion, finely chopped
• 2 large carrots, finely diced
• 1 large potato, finely diced
• 2 cloves garlic, minced
• 2 bay leaves
• 2 (15 ounce) cans white cannellini beans, drained and rinsed
• 2 bunches kale, stems removed and roughly chopped
• 64 oz. good quality low-sodium chicken stock
• Kosher Salt and Freshly Ground Black Pepper, to taste
• 1 loaf baguette bread
• Gruyere and Asiago Cheese, shredded

How to Make (Step-by-Step)

STEP 1

In a large pot, heat 2 tablespoons olive oil over medium heat. Add the sausage and brown it, stirring occasionally and breaking it into smaller pieces—about 10 minutes. I like a little caramelized color here; flavor lives in browned bits, so don’t rush this.

STEP 2

Add the onion, carrots, potato, and bay leaves. Season generously with kosher salt and cook until the vegetables start to soften, about 10 minutes. Keep stirring occasionally so nothing sticks.

STEP 3

Add the garlic and beans, and cook another 2–3 minutes. Toss in the kale and cook until it slightly wilts. Pour in the 64 oz. chicken stock, taste, and season with salt and pepper. Cover with the lid.

STEP 4

Bring the soup to a boil, then reduce heat and keep at a simmer for about 45 minutes. You can simmer a bit longer—this soup forgives you. The potatoes will release starch and thicken the broth nicely.

STEP 5

The soup tastes best the second day. If time allows, cool the soup completely and refrigerate it for the following day. Reheat before serving.

STEP 6

When you’re about ready to serve, slice the baguette. Drizzle each slice with a little olive oil and season with kosher salt. Bake at 350°F for about 5 minutes until toasted. Top with grated Gruyere and Asiago cheese and broil for 2–3 minutes until melted. Don’t wander off—cheese under a broiler goes from golden to charred fast.

STEP 7

Divide the soup among bowls and top with a few slices of cheesy baguette. Honestly, that crispy, cheesy toast is the crown on this humble soup.

Method

This recipe uses a simple sauté-simmer method. Brown the sausage for depth, soften the vegetables to build sweetness, then simmer to marry flavors and thicken naturally. You get a velvety broth without heavy cream. Who knew potatoes could be so sneaky?

Pro Tips for the Best Results

• Brown the sausage well for deeper flavor. Don’t skip this.
• Use low-sodium stock so you control salt levels. You can always add more later.
• Rough chop the kale—small bits melt into the soup better and give a nice mouthfeel.
• Don’t over-broil the toast; watch the cheese like it’s a toddler with a cookie.
• Make it ahead—this soup shines after a night in the fridge. Reheat gently to avoid overcooking the kale.
• Want more body? Smash a few beans against the side of the pot to naturally thicken the stock.

Fun Variations & Topping Ideas

Variations:

• Swap sweet Italian sausage for spicy if you like a kick.
• Use white beans you cooked yourself for a creamier texture.
• Replace kale with Swiss chard or spinach for a milder green.
• Make it vegetarian by using olive oil instead of sausage and adding smoked paprika for depth.

Toppings:

• Shaved Parmesan or extra Gruyere for melty goodness.
• A drizzle of good olive oil and a few chili flakes for heat.
• Toasted pine nuts for crunch if you want to get fancy.
• A squeeze of lemon right before serving brightens the whole bowl.

By the way, if you feel like pairing soups, I sometimes serve this with a heartier side like a ham soup twist I borrowed ideas from—here’s a similar inspiration: a ham and potato soup recipe. Curious? Try both on a chilly weekend and declare yourself a soup sommelier.

Storing and Reheating

• Cool the soup to room temperature within two hours to keep it safe.
• Store in airtight containers for up to 4 days in the fridge.
• For longer storage, freeze in meal-sized portions for up to 3 months.
• Reheat gently on the stovetop over medium-low heat. Add a splash of stock or water if it thickened too much.
• Don’t microwave straight from frozen; let it thaw overnight in the fridge or use a low-power microwave setting while stirring often.

Leftover ideas

Leftovers make great lunches. You can:

• Reheat and top with a fresh drizzle of olive oil and lemon.
• Use leftovers as a sauce base for pasta—throw in cooked pasta, stir, and add grated cheese.
• Blend a cup for a thicker bisque-like lunch if you want something smoother.
• Turn the cheesy baguette into a crouton topping for salads or baked casseroles.

Frequently Asked Questions (FAQ)

Can I use kale stems?

Yes, you can. I usually remove thick stems for texture, but if you finely chop them they add flavor and nutrients. Tough stems take longer to soften, though.

Is canned beans okay?

Absolutely. Canned cannellini beans work perfectly and save time. Rinse them well to remove excess sodium.

Can I make this vegetarian?

Yes. Omit the sausage, use vegetable stock, and add smoked paprika or a splash of soy sauce for umami. Add mushrooms if you miss meaty texture.

How do I prevent over-salty soup?

Always start with low-sodium stock and season gradually. Taste as it simmers and adjust near the end.
