Ingredients for bean and bacon soup recipe slow cooker
Six simple ingredients create this smoky, hearty slow-cooker masterpiece—no fancy prep needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Cannelini Beans (Dry) 🥜 | 1 ½ cups | Rinsed before cooking (about 15 oz dry) |
| Thick-Cut Bacon 🥓 | 12 oz | Chopped into 1/2-inch pieces |
| Yellow Onion 🧅 | 1 whole | Diced into 1/2-inch pieces |
| Carrot 🥕 | 3 whole | Peeled and chopped into 1/2-inch slices |
| Celery Stalks 🧅 | 3 whole | Chopped into 1/2-inch pieces |
| Tomato Paste 🍅 | 2 tbsp | Squeeze tube preferred for ease |
| Worcestershire Sauce 🍶 | 1 tbsp | Classic or vegetarian version |
| Bay Leaves 🌿 | 2 whole | Removed before serving |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh thyme leaves |
| Chicken Broth 💧 | 4 cups | Low-sodium preferred |
| Water 💧 | 2 cups | For broth consistency |
| Salt 🧂 | 1 ½ tsp | Adjust to taste at the end |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening broth |
The bacon is where all the magic happens. Thick-cut bacon from Costco or Trader Joe's gives you the best crispy edges, but any good-quality bacon works. Chop it yourself—pre-chopped often has too much fat. The cannellini beans? Dry beans save money and taste better than canned, but if you're short on time, use no-salt-added canned beans (drained and rinsed). For the broth, low-sodium chicken broth is a must—you'll be adding plenty of salt at the end. Look for brands like Swanson or Pacific Foods at the grocery store.
No Worcestershire sauce? Substitute with 1 tbsp soy sauce plus 1/2 tsp smoked paprika—it's not identical, but it gets you close. Fresh thyme is ideal, but dried works at one-third the amount. The tomato paste can be a squeeze tube from Trader Joe's (no waste!) or a small can. If you're using canned beans, rinse them thoroughly to remove any sodium. For extra depth, add a 1/2 tsp of smoked paprika to the slow cooker with the bacon.
This soup tastes even better the next day—make a double batch if you can. Store in an airtight container in the fridge for 4-5 days or freeze for 3 months. To reheat, just warm on the stove or microwave until bubbly. The bacon stays crispy if you scoop it out before serving, then add it back in at the end. For a quick lunch, serve with crusty bread or crackers—the broth soaks right in.

Step-by-step instructions for slow-cooker bean and bacon soup
Here's how to make this hearty soup with layers of smoky bacon flavor and tender beans.
Cook the Bacon and Sauté the Vegetables
Start by placing the chopped 12 oz thick-cut bacon in a large skillet over medium heat. Cook for 8-10 minutes, stirring occasionally, until the bacon is golden brown and crispy. Use a slotted spoon to transfer the bacon to paper towels to drain, leaving the rendered fat in the skillet.
In the same skillet, add the diced 1 whole yellow onion, chopped 3 whole carrots, and chopped 3 whole celery stalks. Cook for 5-6 minutes, stirring frequently, until the vegetables begin to soften and the onion becomes translucent. You want them to caramelize slightly for deeper flavor.
Build the Soup Base in the Slow Cooker
Transfer the cooked vegetables and bacon fat to your slow cooker. Add the 2 tbsp tomato paste, 1 tbsp Worcestershire sauce, 2 whole bay leaves, and 1 tsp dried thyme. Stir everything together to combine the flavors and distribute the tomato paste evenly.
Next, add the 1.5 cups cannellini beans (dry)—they don’t need to be pre-soaked—and pour in the 4 cups chicken broth and 2 cups water. Sprinkle in the 1.5 tsp salt and 0.5 tsp black pepper. Give it one more stir to ensure all ingredients are well incorporated.
Cook Until Tender and Flavorful
Place the lid on the slow cooker and cook on low heat for 6-7 hours or high heat for 3-4 hours. This long cook time allows the beans to soften completely and the flavors to meld together beautifully. The soup should be thick and hearty, with the beans falling apart easily when pressed with a spoon.
About 30 minutes before the soup is done, stir in the 1 tbsp all-purpose flour. This helps thicken the broth slightly and adds a subtle richness. Taste the soup and adjust the seasoning if needed—you may want to add more salt or pepper to your liking.
Finish and Serve
Once the soup is fully cooked, remove the 2 whole bay leaves with a slotted spoon. Return the bacon to the slow cooker and stir gently to distribute it throughout the soup. Let the soup sit for 5 minutes before serving to allow the flavors to settle.
Serve the soup hot, garnished with extra bacon bits if desired. Each bowl should be packed with smoky, savory flavor, tender beans, and a rich broth that’s perfect for chilly days. Pair it with crusty bread to soak up every last drop of that delicious soup!
Pro Tips For Making Bean And Bacon Soup Recipe Slow Cooker
- CRISP THE BACON FIRST: I learned this the hard way—cooking bacon straight in the slow cooker makes the soup greasy and uneven. Sear the thick-cut bacon in a skillet until crispy, then transfer it to paper towels to drain. That smoky, crunchy bite? Worth the extra 5 minutes.
- SOAK BEANS OVERNIGHT: Skipping the soak with cannellini beans leads to tough, mealy texture in the soup. Toss them in a bowl with plenty of water (about 4 cups per pound) and a pinch of salt, then let them sit for 12 hours. Drain and rinse before adding to the slow cooker—your future self will notice the difference.
- CHOP VEGETABLES UNIFORM: I used to eyeball the onion, carrot, and celery sizes, but that’s how you end up with mushy chunks and crunchy bits. Cut them into ½-inch pieces—small enough to melt into the soup but big enough to keep their shape. Consistency ensures every bite has the same hearty texture.
- USE BROTH, NOT WATER: Water makes the soup bland, but low-sodium chicken or vegetable broth adds depth. For a richer flavor, use 4 cups of broth instead of water—just skip adding extra salt. The bacon and beans already bring enough saltiness; let the broth handle the base.
Flavor customization for this dish
Spicy Kick
For a bold twist, add ½ tsp cayenne pepper or 1 tbsp hot sauce when you stir in the flour at the end. I love using Tabasco for its tangy heat or Frank's RedHot for a smoother burn.
If you're sensitive to spice, start with ¼ tsp cayenne—you can always add more later. 🌶️
Smoky Depth
Enhance the smokiness by adding ½ tsp smoked paprika with the tomato paste, or swap Worcestershire sauce for 1 tbsp liquid smoke (like Colman's). For extra richness, cook the bacon with 1 tsp brown sugar to caramelize it deeper. The slow cooker will amplify these flavors beautifully.
Creamy Texture
For a velvety finish, stir in ½ cup coconut milk or ¼ cup sour cream during the last 30 minutes of cooking. I recommend full-fat coconut milk for the best mouthfeel. This works especially well if you prefer a milder, more comforting soup. The creaminess balances the smoky bacon perfectly.
Herb Variations
Swap thyme for 1 tsp rosemary or ½ tsp oregano for a Mediterranean twist. Fresh herbs like parsley or cilantro add brightness—just stir them in at the very end.
For a rustic touch, add 1 sprig fresh sage when cooking the bacon. Each herb brings a unique depth to the broth.
Vegetable Boost
Add 1 diced potato (peeled, ½-inch cubes) or 1 cup chopped kale with the carrots and celery. Potatoes thicken the soup naturally, while kale adds earthy sweetness. If using kale, remove stems and chop leaves into ¼-inch ribbons for even cooking. 🥕
Protein Swaps
For a vegetarian version, replace bacon with 12 oz smoked tofu (cubed) or ½ lb mushrooms (sautéed with the onions). Use vegetarian Worcestershire sauce and add 1 tsp soy sauce for umami. The slow cooker will keep the tofu tender while developing rich flavors—just stir occasionally to prevent sticking.

Frequently asked questions
Can I use canned beans instead of dry?
Yes! Use 2 (15 oz) cans of no-salt-added cannellini beans, drained and rinsed thoroughly. This saves 6-8 hours of cooking time. Just add them with the broth—they’ll warm through perfectly in the slow cooker. For best flavor, choose brands like Great Northern or Bush’s beans.
How do I keep the bacon crispy?
Cook the bacon in a skillet first until fully crispy, then transfer it to paper towels to drain. Add it back to the soup just 5 minutes before serving—this prevents it from getting soggy. For extra crunch, broil the soup for 2 minutes with the lid off right before serving.
Can I make this soup in an Instant Pot?
Sauté the bacon and veggies first, then add everything else and pressure cook on high for 20 minutes. Let the pressure release naturally for 10 minutes before opening. The Instant Pot version cooks 4x faster but requires stirring the flour in at the very end to avoid clumping.
Why does my soup taste bland?
Slow cookers can dilute flavors—always use low-sodium broth and season generously at the end. For extra depth, add 1 tsp smoked paprika with the tomato paste or a splash of apple cider vinegar (just 1 tsp) to brighten the broth. Taste as you go and adjust salt/pepper gradually.
How long will leftovers keep?
Store in an airtight container in the fridge for 4-5 days or freeze for 3 months. To reheat, warm on the stove over medium-low heat until bubbly—never microwave directly from frozen. The flavors actually improve overnight as they meld further!
