Ingredients You’ll Need

Each ingredient in this Sausage, Fennel, and White Bean Soup Recipe plays its role beautifully—from the fragrant fennel bulb to the creamy beans and savory sausage. Here’s what you need and a few tips for picking the best stuff at the store.

• Olive Oil: Use good quality extra-virgin olive oil for the best flavor and richer aroma when sautéing.
• Italian Pork Sausage: I prefer sweet or mild Italian sausage here, but spicy works great if you like a little kick.
• Fennel Bulb: Fresh and firm bulbs are key—avoid ones that are bruised or soft.
• Yellow Onion: Adds a mellow sweetness and depth to the base of the soup.
• Garlic: Fresh garlic cloves, grated for maximum flavor infusion.
• Fennel Seeds: These amplify the fennel flavor; even a teaspoon adds that subtle anise note.
• Dry White Wine: Choose a dry white wine you’d enjoy drinking since it really boosts the soup’s complexity.
• Chicken or Vegetable Stock: Homemade or store-bought – either works, but quality counts here.
• Fresh Thyme: The herb adds warmth and freshness; dried thyme works if fresh isn’t available.
• White Beans: Cannellini or great northern beans are my favorites because they stay creamy and tender after cooking.
• Salt and Pepper: Essential for seasoning; always taste and adjust to your liking at the end.

Variations

This soup is super forgiving, which means you can easily make it your own. I’ve played around with different proteins and beans to suit what I have on hand or dietary needs.

• Swap the Sausage: I once made this with chicken sausage for a leaner dish and loved the lighter feel it gave the soup.
• Use Different Beans: Navy or garbanzo beans both work wonderfully — I like them especially when I want a bit more texture.
• Add Greens: Toss in kale or spinach at the end for extra color and nutrients.
• Go Vegan: Replace sausage with sautéed mushrooms and use vegetable stock to make this completely plant-based without losing depth.

How to Make Sausage, Fennel, and White Bean Soup Recipe

Step 1: Brown the Sausage

Start by heating olive oil in a large heavy-bottomed pot over medium-high heat. Once shimmering, add the Italian sausage—remove casings first if needed—and cook it in an even layer. Stir occasionally, breaking the sausage into bite-sized pieces with a wooden spoon. Keep going until it’s beautifully browned and cooked through, about 10 minutes. I find not crowding the pan helps get a good sear and richer flavor.

Step 2: Sauté Fennel, Onion, and Garlic

Add diced fennel bulb and onion right into the pot with a big pinch of salt and freshly cracked pepper. Sauté these together until soft and aromatic, about 5–7 minutes—this is when the kitchen starts smelling irresistible. Then stir in grated garlic and fennel seeds, cooking another 2–3 minutes until fragrant. Be careful not to burn the garlic; keep the heat moderate and stir often.

Step 3: Deglaze and Simmer

Pour in the dry white wine, letting it simmer and reduce for a few minutes. Scrape the bottom of the pot with your wooden spoon to loosen all those tasty browned bits—the secret to a deeply flavored soup. When the wine is mostly reduced but still slightly saucy, add the chicken stock, rinsed white beans, fresh thyme sprigs, and some black pepper. Bring everything to a gentle simmer, then cover and turn the heat down low. Let it cook for 20–30 minutes to marry all those flavors.

Step 4: Finish with Fennel Fronds and Season

While the soup simmers, chop some fennel fronds and finely dice a few fennel stalks to keep aside for adding freshness at the end. Once the soup’s done, discard the thyme stems and stir in the fennel fronds for a burst of brightness. Give the soup a final taste and adjust salt and pepper as you like. Serve it warm, and enjoy all those lovely layers of flavor!

How to Serve Sausage, Fennel, and White Bean Soup Recipe

Garnishes

I usually top my bowls with a sprinkle of fresh fennel fronds and a grated shave of Parmesan if I have it handy. A drizzle of good-quality olive oil or a cracking of black pepper never hurts either. These simple garnishes brighten up the bowl and make each serving look restaurant-worthy.

Side Dishes

Crusty bread or garlic baguette slices are perfect for dipping and soaking up the broth. Sometimes I serve it alongside a crisp arugula salad dressed lightly with lemon vinaigrette to add a fresh contrast to the soup’s richness.

Creative Ways to Present

For a more elegant touch at dinner parties, I like to serve the soup in rustic bowls topped with fennel fronds and a few toasted pine nuts for crunch. Setting out a few condiments like chili flakes or herb oil lets guests tailor their bowls to their taste. It’s simple but looks so thoughtful!

Make Ahead and Storage

Storing Leftovers

I store leftover sausage, fennel, and white bean soup in airtight containers in the fridge for up to 4 days. It actually tastes even better the next day once the flavors have had more time to meld, so don’t hesitate to make a big batch!

Freezing

This soup freezes beautifully. I portion it into freezer-safe containers and it keeps well for up to 3 months. Just thaw overnight in the fridge before reheating, which really helps preserve the texture of the sausage and beans.

Reheating

Reheat leftovers gently over low to medium heat on the stove to avoid overcooking the sausage or breaking down the beans. I like to add a splash of stock or water if the soup feels too thick. Stir in fresh fennel fronds or chopped herbs after reheating to refresh the flavors.
