Ingredients for 15 bean soup with italian sausage
Fifteen beans, smoky sausage, and a simmering pot of winter comfort—this is your new go-to stew.
| Ingredient | Amount | Notes |
|---|---|---|
| Italian Sausage 🌭 | 1 ½ lb | Sweet or spicy, casings removed |
| Dried Beans (15 Varieties) 🌱 | 3 cups | Soaked overnight, drained |
| Vegetable Broth 💧 | 6 cups | Low-sodium preferred |
| Tomato Paste 🍅 | ½ cup | Smooth, not chunky |
| Onion 🧅 | 1 whole | Yellow or red, chopped |
| Garlic Cloves 🧄 | 4 cloves | Minced for depth |
| Carrots 🥕 | 2 medium | Peeled, chopped into chunks |
| Celery Stalks 🧅 | 3 whole | Chopped, includes leaves |
| Bay Leaves 🌿 | 2 whole | Dried, removed before serving |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, chopped |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |

The sausage is non-negotiable here. Sweet or spicy Italian—whatever you prefer, just make sure it’s high-quality. Costco or Trader Joe’s have great options, but any local butcher will have a fresh batch. Look for good marbling and avoid anything that smells overly processed. The beans? Dried is best—canned is a pinch, but dried gives you that authentic texture. Soak them overnight in plenty of water (I use a big bowl), then drain and rinse before adding to the pot. Pro tip: if you’re short on time, quick-soak them in boiling water for 2 minutes, then let sit for an hour. The broth matters too—low-sodium vegetable broth keeps the flavor balanced without making the soup taste bland.
No Italian sausage? Spicy chorizo or smoked sausage works in a pinch, but the flavor will shift. Short on dried beans? Mix canned beans (drained and rinsed) with dried—just reduce the canned amount by half. The tomato paste can be swapped for crushed tomatoes (1 cup), but paste gives you that deeper, concentrated flavor. Fresh herbs are ideal, but dried thyme at one-third the amount gets you close. Want more depth? Add a splash of red wine—it cooks off but leaves behind incredible flavor. The carrots and celery can be swapped for potatoes or sweet potatoes if you want extra heartiness, but keep the ratio similar.
This soup tastes even better the next day—honestly, that’s when it shines. Store in the fridge for up to 5 days or freeze for 3 months. I like to portion it into containers so I can grab a bowl anytime. The beans soften more overnight, and the flavors meld into something truly special. If you’re making a big batch, double the broth and beans—it’s worth it. And save those bay leaves and thyme stems for stock! Toss them in a freezer bag with veggie scraps for future broths.

Step-by-step instructions for 15 bean soup with Italian sausage
Here’s how to create a rich, smoky stew that bursts with flavor and texture.
Sauté the Sausage and Vegetables
Heat the 2 tablespoons olive oil in a large Dutch oven over medium-high heat. Add the 1.5 lb Italian sausage, breaking it into bite-sized pieces as it hits the pan. Cook for 5-6 minutes, stirring occasionally, until the sausage is deeply browned and beginning to crisp. This step develops that irresistible smoky depth we’re after.
Push the sausage to one side of the pot and add the chopped onion, chopped carrots, and chopped celery stalks. Cook for 5 minutes, stirring frequently, until the vegetables soften slightly and the onion becomes translucent. Here’s the thing—don’t rush this step. Properly caramelized vegetables form the flavor foundation of this soup.
Add Aromatics and Build the Base
Stir in the 4 cloves minced garlic and cook for 30 seconds until fragrant—you’ll smell that wonderful garlic aroma filling your kitchen. Add the 0.5 cup tomato paste, stirring constantly for 2 minutes until it darkens slightly and coats the vegetables. This creates a rich, slightly sweet base that balances the hearty flavors.
Pour in the 0.5 cup red wine (if using) and scrape up any browned bits from the bottom of the pot. Let it simmer for 3 minutes until the wine reduces by half. The alcohol will cook off, leaving behind concentrated flavor. If you’re skipping the wine, add 1 cup vegetable broth instead to maintain moisture.
Simmer with Beans and Seasonings
Add the 3 cups drained dried beans, 6 cups vegetable broth, 2 whole bay leaves, and 1 tablespoon chopped fresh thyme. Bring to a boil, then reduce heat to low and cover partially. Let it simmer for 1.5 hours, stirring occasionally, until the beans are tender but still hold their shape. This long simmering time is crucial—it allows all the flavors to meld together beautifully.
About 30 minutes into cooking, add the 1.5 teaspoons salt and 0.5 teaspoon black pepper. Taste and adjust seasoning if needed. The beans should be absorbing all that rich flavor from the sausage and vegetables. If the soup looks too thick, add ½ cup water to reach your desired consistency.
Finish and Serve
Remove the 2 whole bay leaves and discard them. Stir in the sausage mixture from earlier, ensuring everything is well combined. Let the soup simmer uncovered for an additional 10-15 minutes to allow any excess moisture to evaporate and the flavors to concentrate.
Taste and adjust seasoning one final time. Ladle the soup into bowls and garnish with 0.25 cup chopped fresh parsley. The bright green parsley adds a fresh contrast to the rich, smoky flavors. Serve immediately with crusty bread to soak up every last drop of that hearty broth.
Pro Tips For Making 15 Bean Soup With Italian Sausage
- Brown the Sausage First: DESCRIPTION: Don’t just toss those sausage links into the pot raw—sizzle them in a dry skillet over medium-high heat until deeply browned, about 3-4 minutes per side. That crust locks in flavor and keeps the soup from tasting like bland, undercooked meat. (Yes, even if you’re tempted to skip it.)
- Soak Beans in Cold Water: DESCRIPTION: Dump all 15 bean varieties into a large bowl, cover with cold water, and let them sit for at least 2 hours—or overnight if you’re planning ahead. Warm water speeds up soaking but can leach out starches, making your soup gummy. Cold water keeps them firm and flavorful.
- Simmer, Don’t Boil: DESCRIPTION: Once everything’s in the pot, keep the heat low enough that only tiny bubbles break the surface—no rolling boil. High heat turns beans mushy and makes the broth cloudy. A gentle simmer (about 15-20 minutes after boiling starts) keeps them intact and the broth clear.
- Stir in Tomato Paste Late: DESCRIPTION: Wait until the beans and sausage have simmered for 45 minutes before adding that tomato paste—otherwise, it’ll burn before the beans soften. Mix it into a little broth first, then stir it in. This ensures it blends smoothly without scorching. (Trust me, burnt tomato paste tastes like regret.)
Make-ahead tips for this recipe
Overnight Prep
The key to making this soup ahead of time is starting with soaked beans. Place 3 cups dried beans in a large bowl and cover with plenty of water (about 2 inches above the beans). Let them soak overnight—this ensures they cook evenly and reduces the total simmering time.
I like to use a glass bowl so I can see the water level. Drain and rinse the beans before adding them to the pot the next day. 🌱
Freezer-Friendly
This soup freezes beautifully, making it perfect for batch cooking. After simmering, let it cool completely, then transfer to airtight containers or heavy-duty freezer bags. Leave 1 inch of headspace for expansion. Label with the date and freeze for up to 3 months.
When reheating, thaw overnight in the fridge, then warm on the stovetop over low heat with a splash of broth to restore moisture. ❄️
Portion Control
For easy reheating, divide the soup into quart-sized containers before freezing. This way, you can grab a single portion without thawing the entire batch. I like to store them in glass Pyrex containers because they reheat evenly and are microwave-safe.
Just pop one in the microwave for 3-4 minutes on 50% power, stirring halfway through. 🍲
Make-Ahead Broth Boost
If you’re prepping for a crowd, make a big pot of broth first and store it separately. Use 8 cups broth instead of 6, then freeze the extra in 1-cup portions.
When you’re ready to cook, just thaw one portion and add it to the simmering soup to maintain the right consistency. This trick saves time and ensures your soup stays flavorful even after reheating. 💡
Day-Old Flavor
Honestly, this soup tastes even better the next day. The flavors deepen as the beans absorb more of the smoky sausage and aromatic broth. If you’re prepping for a meal, cook it the night before and let it sit overnight in the fridge.
The texture becomes creamier, and the seasoning balances perfectly. Just reheat gently on the stove to preserve all that rich flavor. 💛
Slow Cooker Hack
For ultimate convenience, use a 6-quart slow cooker to make this soup ahead of time. Sauté the sausage and vegetables as directed, then transfer everything to the slow cooker with the beans and broth.
Cook on low for 6-8 hours or high for 3-4 hours. The slow cooker does all the work while you’re out, and the results are just as flavorful. Perfect for busy weeknights! ⏰

Frequently asked questions
Can I substitute Italian sausage for another type?
Yes! For a milder flavor, try mild chorizo or smoked sausage. If you prefer spicier, spicy Italian sausage or Calabrese sausage work well. Just adjust the heat level to your taste—remove some of the seasoning if needed.
How do I make this soup vegetarian?
Swap the sausage for 1.5 cups of mushrooms (cremini or portobello) or 1 can of lentils (drained and rinsed). Add 1 teaspoon smoked paprika for depth, and boost the broth with 1 extra bay leaf and 1 teaspoon liquid smoke (optional). The texture will be just as hearty!
Why do my beans turn mushy?
Overcooking is the most common cause. Beans should be tender but still hold their shape—check them at 1 hour of simmering. If using canned beans, reduce cooking time to 30-45 minutes and avoid high heat. Also, never skip soaking dried beans—it prevents uneven texture.
Can I use canned beans instead of dried?
Use 2 (15 oz) cans of mixed beans (drained and rinsed) for every 1 cup dried. Since canned beans cook faster, reduce the simmering time to 45-60 minutes and add them in the last 30 minutes of cooking. The flavor will still be rich, just slightly less textured.
What’s the best way to reheat leftovers?
Gently reheat on the stovetop over low heat with a splash of broth or water to restore moisture. Avoid microwaving—it can make the beans rubbery. For best results, stir occasionally and heat until just simmering (10-15 minutes). The soup tastes even better reheated!
